Recovery from addiction is a complex and emotionally taxing process that involves much more than simply abstaining from substance use. It necessitates a holistic approach to healing, which often includes medical treatment, psychotherapy, lifestyle changes, and, for many people, the support of loved ones.
Another source of support that is increasingly recognized for its therapeutic benefits is the companionship of pets. Whether it’s a dog, a cat, or even a bird, pets offer emotional sustenance, non-judgmental companionship, and numerous practical advantages. In this article from Learning from Dogs, we delve into how the presence of a pet can be a transformative experience.
It’s All About a Good Routine
Establishing a stable routine is a cornerstone of addiction recovery. A routine not only provides structure to the day but also instills a sense of responsibility and purpose. Owning a pet naturally requires a routine for feeding, exercise, and care.
This routine can help an individual in recovery stay focused and reduce the void or emptiness often cited as a relapse trigger. Technologies like automated pet feeders can further support this routine, ensuring that your responsibilities are met even when you’re dealing with emotional ups and downs.
Pets Just Make You Feel Better
PsychCentral notes that interacting with pets has been scientifically shown to improve emotional health. Simple actions such as petting a dog or cat trigger the release of “feel-good” hormones like oxytocin, reducing stress and elevating mood.
These emotional benefits are invaluable, especially during the psychologically taxing phases of withdrawal and detoxification. Mental health tracking apps can provide real-time data on your emotional state, often reflecting an improvement correlated with increased time spent with your pet.
Pet-Friendliness and Rehab
Selecting the appropriate rehab facility is an essential step toward a successful recovery journey. An important criterion to consider is the availability of pet-friendly options or the incorporation of pet therapy in the facility’s treatment approach.
Many centers, including local resources for treatment and recovery, are increasingly acknowledging the multifaceted therapeutic advantages that pets can offer and are thus integrating them into their treatment regimens. Specialized online platforms provide comprehensive data about such pet-amicable facilities, empowering individuals to make a well-informed decision.
Diverting from Destructive Urges
Engaging with pets can provide a crucial distraction from cravings and negative thoughts. Whether it’s going for a walk, playing fetch, or simply cuddling on the sofa, these activities require engagement that diverts attention away from destructive patterns. There are even interactive pet toys available now, controlled via smartphone apps, that can keep both the pet and the owner engaged, further reducing idle time that might otherwise lead to cravings.
Pets Make You Social
HABRI points out that owning a pet often encourages social interaction, which can be particularly beneficial during recovery. Whether it’s through meeting other dog owners during walks or engaging in community pet events, these interactions foster a sense of community and belonging. These newly formed social connections can be a significant supportive element in staying sober. Social platforms and apps for pet owners offer a virtual space to connect, share experiences, and seek advice, contributing to a broader support system.
Enhancing Self-Image
Successfully caring for a pet significantly boosts self-esteem and self-worth. Taking responsibility for the well-being of another life generates a sense of accomplishment and purpose, which are foundational in rebuilding one’s life after addiction. Virtual training modules and online courses offer valuable insights into pet care, further increasing competence and confidence in this area.
The journey through addiction recovery is seldom straightforward. It’s a path fraught with challenges, emotional turbulence, and setbacks. However, the simple act of caring for a pet offers an unmatched emotional and practical support system that aids significantly in the recovery process. From establishing routine and boosting emotional well-being to providing a sense of purpose, the benefits are multi-layered and profound. As you navigate through the trials of addiction recovery, the companionship of a pet can become one of your most significant sources of comfort, strength, and hope.
Learning from Dogs serves as a reminder of the values of life and the power of unconditional love – as so many, many dogs prove each and every day. Read more informative articles today!

How To Style Your Home for a Successful Sale As a Pet Owner
By Penny Martin

Selling a home is a pivotal moment, and it’s often laden with challenges, especially for pet owners. Pets are integral to many families, yet their presence in a home can affect its market appeal. The key to success lies in presenting a home that is inviting to a broad range of buyers, creating a balance where your pet-friendly environment is subtly perceptible but not overtly dominant. This comprehensive guide, presented by Learning From Dogs, delves into effective strategies for preparing your home for sale, ensuring it is welcoming and appealing to potential buyers while accommodating your pets in an understated manner.
Refurbish Pet-Caused Damages
Initiate the home staging process by addressing any visible pet-related damage. This includes repairing scratched floors, restoring torn carpets, and replacing chewed baseboards or door frames. Undertaking these repairs is essential, as it enhances the aesthetic appeal of your home and demonstrates to potential buyers that the property has been meticulously cared for. This attention to detail not only increases the home’s visual appeal but also instills confidence in buyers about the overall maintenance of the property. It’s also a good idea to take proactive measures that will prevent your pet from exhibiting destructive behaviors in your new place.
Deep Cleaning for a Pristine Look
The importance of a thoroughly cleaned home cannot be overstated. This means going beyond the usual cleaning routine to focus on eradicating pet hair, dander, and any trace of pets. Consider the benefits of a professional cleaning service to ensure a comprehensive and meticulous result. A spotlessly clean home not only presents well but also communicates a sense of pride and care in property maintenance. It’s a visual reassurance to buyers that the home has been well-loved and looked after.
Market Research for Competitive Edge
Conducting thorough market research is a pivotal step in the home-selling process. Investigate how comparable homes in your locality are presented in the market. Pay close attention to their staging techniques, pricing strategies, and how they highlight their homes’ best features. This research will arm you with knowledge and insights, enabling you to position your home competitively in the market. Understanding the local real estate landscape helps in making informed decisions about how to best showcase your home to attract the right buyers.
Eliminating Pet Odors
Neutralizing pet odors is a critical aspect of home staging. Utilize air purifiers, scented candles, and specialized odor-neutralizing products to ensure your home smells inviting. Regularly airing out the house also plays a crucial role in maintaining a pleasant and fresh atmosphere. Remember, the olfactory experience can greatly influence a buyer’s first impression, so a fresh-smelling home is key to creating a positive and lasting impact.
Stowing Away Pet Supplies
During property viewings, it’s advisable to temporarily remove all visible pet supplies, including food bowls, toys, beds, and litter boxes. You can also do this with personal items such as family photos. This tactic helps potential buyers focus on the space itself without distractions. Creating an environment where buyers can easily envision their own life and belongings in the space is crucial for forming an emotional connection with the property.
Clearing Out Pet Furniture
Consider storing or temporarily replacing pet-specific furniture, such as cat trees, dog beds, and pet crates, as well as large pieces of your own furniture. This not only declutters the space but also allows potential buyers to appreciate the full potential and size of each room. Clearing these items creates an impression of more space and versatility, appealing to a wider range of buyer preferences.
Selecting Pet-Friendly Fabrics
Switch to fabrics that are less prone to trapping pet hair and odors. Opt for easy-to-clean furniture covers that complement your home’s decor. Neutral tones and textures can make a significant difference, as they help potential buyers envision their own furniture and style in the space. This subtle change can enhance the overall appeal of your home, making it more attractive to a diverse group of buyers.
Navigating the home-selling journey as a pet owner requires a strategic and thoughtful approach. By implementing these tailored strategies, you can ensure your home is showcased as a welcoming, pet-neutral space, appealing to a broad spectrum of buyers. A well-prepared, immaculately clean, and thoughtfully staged home increases the likelihood of attracting serious buyers and achieving a successful sale. Remember, the goal is to present a home that resonates with buyers’ aspirations, creating an environment where they can easily envision building their future.

Thank you, Penny.
Hopefully this will be on interest to our readers. I, certainly, found it so. Plus, I was more than grateful for the LfD references in the article. Once again, thank you, Penny.
So here we are, 2024, and the year when I become 80! However, I still have eleven months before that happens. Like an amazing number of people, I do not really think long about this New Year but there are plenty that do.
Here is an article that explains much more. It is from The Conversation.

What winter solstice rituals tell us about indigenous people
On the day of winter solstice, many Native American communities will hold religious ceremonies or community events.
The winter solstice is the day of the year when the Northern Hemisphere has the fewest hours of sunlight and the Southern Hemisphere has the most. For indigenous peoples, it has been a time to honor their ancient sun deity. They passed their knowledge down to successive generations through complex stories and ritual practices.
As a scholar of the environmental and Native American religion, I believe, there is much to learn from ancient religious practices.
Ancient architecture
For decades, scholarshave studied the astronomical observations that ancient indigenous people made and sought to understand their meaning.
One such place was at Cahokia, near the Mississippi River in what is now Illinois across from St. Louis.
In Cahokia, indigenous people built numerous temple pyramids or mounds, similar to the structures built by the Aztecs in Mexico, over a thousand years ago. Among their constructions, what most stands out is an intriguing structure made up of wooden posts arranged in a circle, known today as “Woodhenge.”
To understand the purpose of Woodhenge, scientists watched the sun rise from this structure on winter solstice. What they found was telling: The sun aligned with both Woodhenge and the top of a temple mound – a temple built on top of a pyramid with a flat top – in the distance. They also found that the sun aligns with a different temple mound on summer solstice.
Archaeological evidence suggests that the people of Cahokia venerated the sun as a deity. Scholars believe that ancient indigenous societies observed the solar system carefully and wove that knowledge into their architecture.
Scientists have speculated that the Cahokia held rituals to honor the sun as a giver of life and for the new agricultural year.
Complex understandings
Zuni Pueblo is a contemporary example of indigenous people with an agricultural society in western New Mexico. They grow corn, beans, squash, sunflowers and more. Each year they hold annual harvest festivals and numerous religious ceremonies, including at the winter solstice.
At the time of the winter solstice they hold a multiday celebration, known as the Shalako festival. The days for the celebration are selected by the religious leaders. The Zuni are intensely private, and most events are not for public viewing.
But what is shared with the public is near the end of the ceremony, when six Zuni men dress up and embody the spirit of giant bird deities. These men carry the Zuni prayers for rain “to all the corners of the earth.” The Zuni deities are believed to provide “blessings” and “balance” for the coming seasons and agricultural year.
As religion scholar Tisa Wenger writes, “The Zuni believe their ceremonies are necessary not just for the well-being of the tribe but for “the entire world.”
Winter games
Not all indigenous peoples ritualized the winter solstice with a ceremony. But that doesn’t mean they didn’t find other ways to celebrate.
The Blackfeet tribe in Montana, where I am a member, historically kept a calendar of astronomical events. They marked the time of the winter solstice and the “return” of the sun or “Naatosi” on its annual journey. They also faced their tipis – or portable conical tents – east toward the rising sun.
They rarely held large religious gatherings in the winter. Instead the Blackfeet viewed the time of the winter solstice as a time for games and community dances. As a child, my grandmother enjoyed attending community dances at the time of the winter solstice. She remembered that each community held their own gatherings, with unique drumming, singing and dance styles.
Later, in my own research, I learned that the Blackfeet moved their dances and ceremonies during the early reservation years from times on their religious calendar to times acceptable to the U.S. government. The dances held at the time of the solstice were moved to Christmas Day or to New Year’s Eve.
Today, my family still spends the darkest days of winter playing card games and attending the local community dances, much like my grandmother did.
Although some winter solstice traditions have changed over time, they are still a reminder of indigenous peoples understanding of the intricate workings of the solar system. Or as the Zuni Pueblo’s rituals for all peoples of the earth demonstrate – of an ancient understanding of the interconnectedness of the world.
I make no apologies for returning to the subject of scams and fakes. Because the advances in the equipment we have for viewing the internet are growing appreciably, and quickly.
We should include scams in this topic. Just a couple of days ago I had a text on my cell-phone that purported to have come from the United States Post Office, the USPS, and at first I was taken in. Luckily I left it for a while and then discovered it was a scam.

No, you’re not that good at detecting fake videos − 2 misinformation experts explain why and how you can develop the power to resist these deceptions
By
Sam Wineburg Professor of Education and (by courtesy) History, Stanford University
Michael Caulfield Research Scientist, Center for an Informed Public, University of Washington
Someone tracking the conflict raging in the Middle East could have seen the following two videos on social media. The first shows a little boy hovering over his father’s dead body, whimpering in Arabic, “Don’t leave me.” The second purports to show a pregnant woman with her stomach slashed open and claims to document the testimony of a paramedic who handled victims’ bodies after Hamas’ attack in Israel on Oct. 7, 2023.
Even though these videos come from different sides of the Israel-Hamas war, what they share far exceeds what separates them. Because both videos, though real, have nothing to do with the events they claim to represent. The clip of the boy is from Syria in 2016; the one of the woman is from Mexico in 2018.
Cheap but effective fakes
Recent headlines warn of sophisticated, AI-driven deepfakes. But it is low-tech cheap fakes like these that fuel the latest round of disinformation. Cheap fakes are the Swiss army knife in the propagandist’s tool belt. Changing a date, altering a location or even repurposing a clip from a video game and passing it off as battlefield combat require little know-how yet effectively sow confusion.
The Israel-Hamas war has unleashed a flood of fake videos on social media.
The good news is that you can avoid being taken in by these ruses – not by examining the evidence closely, which is liable to mislead you, but by waiting until trusted sources verify what you’re looking at. This is often hard to do, however.
In the largest survey of its kind, 3,446 high school students evaluated a video on social media that purported to show election fraud in the 2016 Democratic primary. Students could view the whole video, part of it or leave the footage to search the internet for information about it. Typing a few keywords into their browsers would have led students to articles from Snopes and the BBC debunking the video. Only three students – less than one-tenth of 1% – located the true source of the video, which had, in fact, been shot in Russia.
Your lying eyes
Why were students so consistently duped? The problem, we’ve found, is that many people, young and old alike, think they can look at something online and tell what it is. You don’t realize how easily your eyes can be deceived – especially by footage that triggers your emotions.
When an incendiary video dodges your prefrontal cortex and lands in your solar plexus, the first impulse is to share your outrage with others. What’s a better course of action? You might assume that it is to ask whether the clip is true or false. But a different question – rather, a set of related questions – is a better starting place.
Do you really know what you’re looking at?
Can you really tell whether the footage is from atrocities committed by Russian forces in the Donbas just because the headline blares it and you’re sympathetic to the Ukrainian cause?
Is the person who posted the footage an established reporter, someone who risks their status and prestige if it turns out to be fake, or some random person?
Is there a link to a longer video – the shorter the clip, the more you should be wary – or does it claim to speak for itself, even though the headline and caption leave little room for how to connect the dots?
These questions require no advanced knowledge of video forensics. They require you only to be honest with yourself. Your inability to answer these questions should be enough to make you realize that, no, you don’t really know what you’re looking at.
Patience is a powerful tool
Social media reports of “late-breaking news” are not likely to be reporting at all, but they are often pushed by rage merchants wrapping an interpretation around a YouTube video accompanied by lightning bolt emojis and strings of exclamation points. Reliable reporters need time to establish what happened. Rage merchants don’t. The con artist and the propagandist feed on the impatient. Your greatest information literacy superpower is learning to wait.
If there are legs to the video, rest assured you’re not the only one viewing it. There are many people, some of whom have mastered advanced techniques of video analysis, who are likely already analyzing it and trying to get to the bottom of it.
You won’t have to wait long to learn what they’ve found.
“The Future of Democracy” is, for me, incredibly interesting.
I haven’t a clue as to how long I have been listening to the annual Reith Lecture on BBC Radio 4. It has been many years.
As Wikipedia explains:
The Reith Lectures is a series of annual BBCradiolectures given by leading figures of the day. They are commissioned by the BBC and broadcast on Radio 4 and the World Service. The lectures were inaugurated in 1948 to mark the historic contribution made to public service broadcasting by Lord Reith, the corporation’s first director-general.
Reith maintained that broadcasting should be a public service that aimed to enrich the intellectual and cultural life of the nation. It is in this spirit that the BBC each year invites a leading figure to deliver the lectures. The aim is to advance public understanding and debate about issues of contemporary interest.
Wikipedia
From the BBC’s History of the BBC.
As the BBC explains on the BBC Sounds website:
Released On: 29 Nov 2023
Available for over a year
This year’s BBC Reith Lecturer is Ben Ansell, Professor of Comparative Democratic Institutions at Nuffield College, Oxford University.
He will deliver four lectures called “Our Democratic Future,” asking how we can build a politics that works for all of us with systems which are robust to the challenges of the twenty first century, from climate change to artificial intelligence. In this first lecture, recorded at New Broadcasting House in London in front of an audience, Professor Ansell asks whether we are in a ‘democratic recession’, where longstanding democracies are at risk of breakdown and authoritarianism is resurgent. And he examines how resilient democracies are to the challenges of artificial intelligence, social media and if they can effectively address core challenges from climate change to inequality.
The Reith Lectures are presented by Anita Anand and produced by Jim Frank. The Editor is China Collins. Reith Co-ordinator is Brenda Brown. The series is mixed by Rod Farquhar and Neil Churchill.

Developing a Effective Dog Training Philosophy: Techniques and Strategies
Dog training philosophy refers to the underlying principles and beliefs that guide how dog owners train and interact with their furry companions. Different dog owners have different philosophies when it comes to training their dogs, and each approach can have a significant impact on the dog’s behavior and well-being.
In this article, we’ll explore the different dog training philosophies and the benefits and drawbacks of each approach.
Positive Reinforcement
Positive reinforcement is a popular dog training philosophy that involves rewarding desired behaviors with treats, praise, or other positive stimuli. The idea is to encourage dogs to repeat behaviors that lead to positive outcomes while discouraging behaviors that lead to negative outcomes.
Positive reinforcement is a humane and effective way to train dogs. It builds trust and strengthens the bond between the owner and the dog. It’s also an enjoyable and rewarding experience for both the dog and the owner.
One potential drawback of positive reinforcement is that it can be time-consuming. Owners must be patient and consistent in rewarding desired behaviors, and it may take longer for some dogs to learn new behaviors than others.
Punishment-Based Training
Punishment-based training is a dog training philosophy that involves punishing undesirable behaviors with negative stimuli, such as physical correction or verbal scolding. The idea is to discourage dogs from repeating behaviors that lead to negative outcomes while encouraging behaviors that lead to positive outcomes.
Punishment-based training can be effective in stopping unwanted behaviors quickly. However, it can also have negative consequences for the dog’s emotional well-being. Dogs that are punished frequently may become fearful or aggressive, and their trust in their owners may be damaged.
Moreover, punishment-based training can result in a negative relationship between the owner and the dog. Dogs may learn to fear their owners, which can lead to a breakdown in communication and a lack of trust.
Dominance-Based Training
Dominance-based training is a dog training philosophy that is based on the belief that dogs are pack animals that instinctively seek to establish a social hierarchy. The idea is to assert dominance over the dog and establish the owner as the pack leader.
Dominance-based training can be effective in certain situations, such as when dealing with aggressive dogs. However, it can also be harmful to the dog’s emotional well-being. Dogs that are subjected to dominance-based training may become fearful, anxious, or aggressive, and their trust in their owners may be damaged.
Moreover, the concept of dominance in dog behavior has been debunked by many dog behaviorists and trainers. While dogs do live in social groups and establish hierarchies, the idea that dogs constantly seek to establish dominance over their owners is not supported by scientific evidence.
Relationship-Based Training
Relationship-based training is a dog training philosophy that is based on the belief that dogs are social animals that thrive on positive interactions with their owners. The idea is to build a strong, positive relationship between the owner and the dog, which will lead to a well-behaved and happy dog.
Relationship-based training is a humane and effective way to train dogs. It emphasizes positive reinforcement and building a strong bond between the owner and the dog. It also encourages owners to understand their dog’s behavior and to communicate effectively with their furry companion.
One potential drawback of relationship-based training is that it can be time-consuming. It requires a significant amount of effort and dedication on the part of the owner to build a strong relationship with their dog. Moreover, some dogs may require more time and effort to establish a strong bond with their owner.
Balanced Training
Balanced training is a dog training philosophy that combines elements of positive reinforcement, punishment-based training, and dominance-based training. The idea is to use a variety of training methods to achieve the desired behavior in the dog.
Balanced training can be effective in certain situations, such as when dealing with complex behavior issues. However, it can also be confusing and overwhelming for dogs. They may not understand what behavior is being rewarded or punished, and their trust in their owner may be compromised.
Moreover, balanced training can lead to a lack of consistency in the training approach, which can confuse the dog and make it difficult for them to learn new behaviors.
Conclusion
In conclusion, there are different dog training philosophies, and each approach can have a significant impact on the dog’s behavior and well-being. Positive reinforcement and relationship-based training are generally considered to be the most humane and effective ways to train dogs. Punishment-based and dominance-based training can have negative consequences for the dog’s emotional well-being and may damage the relationship between the owner and the dog.
Balanced training can be effective in certain situations, but it requires a significant amount of skill and knowledge to implement properly. Moreover, it can be confusing and overwhelming for dogs, and their trust in their owner may be compromised.
As a dog owner, it’s essential to understand the different dog training philosophies and choose the approach that best suits your dog’s needs and personality. It’s also essential to seek the advice of a professional dog trainer or behaviorist if you’re experiencing issues with your dog’s behavior. A trained professional can help you identify the underlying causes of your dog’s behavior and develop a training plan that will address those issues effectively.
In the end, the goal of dog training should be to build a strong, positive relationship between the owner and the dog. When dogs are well-trained, happy, and healthy, they make wonderful companions and enrich our lives in countless ways. By choosing the right dog training philosophy and approach, you can help your furry friend become the best possible version of themselves.

As I said at the beginning, I hope republishing this text is alright. Because I think it is a very good article from a very useful website.
Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth.
To astronomers, the wavelength of light a galaxy emits is longer the faster the galaxy is moving away from us. The farther away the galaxy is, the more its light has shifted toward the longer wavelengths on the red side of the spectrum – so the higher the “redshift.”
Because the speed of light is finite, fast, but not infinitely fast, seeing something far away means we’re looking at the thing how it looked in the past. With distant, high-redshift galaxies, we’re seeing the galaxy when the universe was in a younger state. So “high redshift” corresponds to the early times in the universe, and “low redshift” corresponds to the late times in the universe.
But as astronomers have studied these distances, they’ve learned that the universe is not just expanding – its rate of expansion is accelerating. And that expansion rate is even faster than the leading theory predicts it should be, leaving cosmologists like me puzzled and looking for new explanations.
Dark energy and a cosmological constant
Scientists call the source of this acceleration dark energy. We’re not quite sure what drives dark energy or how it works, but we think its behavior could be explained by a cosmological constant, which is a property of spacetime that contributes to the expansion of the universe.
Albert Einstein originally came up with this constant – he marked it with a lambda in his theory of general relativity. With a cosmological constant, as the universe expands, the energy density of the cosmological constant stays the same.
Imagine a box full of particles. If the volume of the box increases, the density of particles would decrease as they spread out to take up all the space in the box. Now imagine the same box, but as the volume increases, the density of the particles stays the same.
It doesn’t seem intuitive, right? That the energy density of the cosmological constant does not decrease as the universe expands is, of course, very weird, but this property helps explain the accelerating universe.
A standard model of cosmology
Right now, the leading theory, or standard model, of cosmology is called “Lambda CDM.” Lambda denotes the cosmological constant describing dark energy, and CDM stands for cold dark matter. This model describes both the acceleration of the universe in its late stages as well as the expansion rate in its early days.
Specifically, the Lambda CDM explains observations of the cosmic microwave background, which is the afterglow of microwave radiation from when the universe was in a “hot, dense state” about 300,000 years after the Big Bang. Observations using the Planck satellite, which measures the cosmic microwave background, led scientists to create the Lambda CDM model.
Fitting the Lambda CDM model to the cosmic microwave background allows physicists to predict the value of the Hubble constant, which isn’t actually a constant but a measurement describing the universe’s current expansion rate.
But the Lambda CDM model isn’t perfect. The expansion rate scientists have calculated by measuring distances to galaxies, and the expansion rate as described in Lambda CDM using observations of the cosmic microwave background, don’t line up. Astrophysicists call that disagreement the Hubble tension.
The universe is expanding faster than predicted by popular models in cosmology. NASA
The Hubble tension
Over the past few years, I’ve been researching ways to explain this Hubble tension. The tension may be indicating that the Lambda CDM model is incomplete and physicists should modify their model, or it could indicate that it’s time for researchers to come up with new ideas about how the universe works. And new ideas are always the most exciting things for a physicist.
One way to explain the Hubble tension is to modify the Lambda CDM model by changing the expansion rate at low redshift, at late times in the universe. Modifying the model like this can help physicists predict what sort of physical phenomena might be causing the Hubble tension.
For instance, maybe dark energy is not a cosmological constant but instead the result of gravity working in new ways. If this is the case, dark energy would evolve as the universe expands – and the cosmic microwave background, which shows what the universe looked like only a few years after its creation, would have a different prediction for the Hubble constant.
But, my team’s latest research has found that physicists can’t explain the Hubble tension just by changing the expansion rate in the late universe – this whole class of solutions falls short.
Developing new models
To study what types of solutions could explain the Hubble tension, we developed statistical tools that enabled us to test the viability of the entire class of models that change the expansion rate in the late universe. These statistical tools are very flexible, and we used them to match or mimic different models that could potentially fit observations of the universe’s expansion rate and might offer a solution to the Hubble tension.
The models we tested include evolving dark energy models, where dark energy acts differently at different times in the universe. We also tested interacting dark energy-dark matter models, where dark energy interacts with dark matter, and modified gravity models, where gravity acts differently at different times in the universe.
But none of these could fully explain the Hubble tension. These results suggest that physicists should study the early universe to understand the source of the tension.
We take it for granted! Of that I am sure. But the question of how oxygen first came to be built up in our atmosphere is fascinating. There was a recent article written by Elizabeth Swanner, who is Associate Professor of Geology, Iowa State University that was published in The Conversation. It makes for a very interesting read.

A layered lake is a little like Earth’s early oceans − and lets researchers explore how oxygen built up in our atmosphere billions of years ago

Little Deming Lake doesn’t get much notice from visitors to Itasca State Park in Minnesota. There’s better boating on nearby Lake Itasca, the headwaters of the Mississippi River. My colleagues and I need to maneuver hundreds of pounds of equipment down a hidden path made narrow by late-summer poison ivy to launch our rowboats.
But modest Deming Lake offers more than meets the eye for me, a geochemist interested in how oxygen built up in the atmosphere 2.4 billion years ago. The absence of oxygen in the deep layers of Deming Lake is something this small body of water has in common with early Earth’s oceans.
On each of our several expeditions here each year, we row our boats out into the deepest part of the lake – over 60 feet (18 meters), despite the lake’s surface area being only 13 acres. We drop an anchor and connect our boats in a flotilla, readying ourselves for the work ahead.

Deming Lake is meromictic, a term from Greek that means only partially mixing. In most lakes, at least once a year, the water at the top sinks while the water at the bottom rises because of wind and seasonal temperature changes that affect water’s density. But the deepest waters of Deming Lake never reach the surface. This prevents oxygen in its top layer of water from ever mixing into its deep layer.
Less than 1% of lakes are meromictic, and most that are have dense, salty bottom waters. Deming Lake’s deep waters are not very salty, but of the salts in its bottom waters, iron is one of the most abundant. This makes Deming Lake one of the rarest types of meromictic lakes.

The lake surface is calm, and the still air is glorious on this cool, cloudless August morning. We lower a 2-foot-long water pump zip-tied to a cable attached to four sensors. The sensors measure the temperature, amount of oxygen, pH and amount of chlorophyll in the water at each layer we encounter. We pump water from the most intriguing layers up to the boat and fill a myriad of bottles and tubes, each destined for a different chemical or biological analysis.
My colleagues and I have homed in on Deming Lake to explore questions about how microbial life adapted to and changed the environmental conditions on early Earth. Our planet was inhabited only by microbes for most of its history. The atmosphere and the oceans’ depths didn’t have much oxygen, but they did have a lot of iron, just like Deming Lake does. By investigating what Deming Lake’s microbes are doing, we can better understand how billions of years ago they helped to transform the Earth’s atmosphere and oceans into what they’re like now.

At Deming Lake, my colleagues and I pay special attention to the water layer where the chlorophyll readings jump. Chlorophyll is the pigment that makes plants green. It harnesses sunlight energy to turn water and carbon dioxide into oxygen and sugars. Nearly 20 feet (6 meters) below Deming’s surface, the chlorophyll is in cyanobacteria and photosynthetic algae, not plants.
But the curious thing about this layer is that we don’t detect oxygen, despite the abundance of these oxygen-producing organisms. This is the depth where iron concentrations start to climb to the high levels present at the lake’s bottom.
This high-chlorophyll, high-iron and low-oxygen layer is of special interest to us because it might help us understand where cyanobacteria lived in the ancient ocean, how well they were growing and how much oxygen they produced.
We suspect the reason cyanobacteria gather at this depth in Deming Lake is that there is more iron there than at the top of the lake. Just like humans need iron for red blood cells, cyanobacteria need lots of iron to help catalyze the reactions of photosynthesis.
A likely reason we can’t measure any oxygen in this layer is that in addition to cyanobacteria, there are a lot of other bacteria here. After a good long life of a few days, the cyanobacteria die, and the other bacteria feed on their remains. These bacteria rapidly use up any oxygen produced by still photosynthesizing cyanobacteria the way a fire does as it burns through wood.
We know there are lots of bacteria here based on how cloudy the water is, and we see them when we inspect a drop of this water under a microscope. But we need another way to measure photosynthesis besides measuring oxygen levels.
Long-running lakeside laboratory
The other important function of photosynthesis is converting carbon dioxide into sugars, which eventually are used to make more cells. We need a way to track whether new sugars are being made, and if they are, whether it’s by photosynthetic cyanobacteria. So we fill glass bottles with samples of water from this lake layer and seal them tight with rubber stoppers.
We drive the 3 miles back to the Itasca Biological Station and Laboratories where we will set up our experiments. The station opened in 1909 and is home base for us this week, providing comfy cabins, warm meals and this laboratory space.
In the lab, we inject our glass bottle with carbon dioxide that carries an isotopic tracer. If cyanobacteria grow, their cells will incorporate this isotopic marker.
We had a little help to formulate our questions and experiments. University of Minnesota students attending summer field courses collected decades worth of data in Itasca State Park. A diligent university librarian digitized thousands of those students’ final papers.
My students and I pored over the papers concerning Deming Lake, many of which tried to determine whether the cyanobacteria in the chlorophyll-rich layer are doing photosynthesis. While most indicated yes, those students were measuring only oxygen and got ambiguous results. Our use of the isotopic tracer is trickier to implement but will give clearer results.

That afternoon, we’re back on the lake. We toss an anchor; attached to its rope is a clear plastic bag holding the sealed bottles of lake water now amended with the isotopic tracer. They’ll spend the night in the chlorophyll-rich layer, and we’ll retrieve them after 24 hours. Any longer than that and the isotopic label might end up in the bacteria that eat the dying cyanobacteria instead of the cyanobacteria themselves. We tie off the rope to a floating buoy and head back to the station’s dining hall for our evening meal.
Iron, chlorophyll, oxygen
The next morning, as we wait for the bottles to finish their incubation, we collect water from the different layers of the lake and add some chemicals that kill the cells but preserve their bodies. We’ll look at these samples under the microscope to figure out how many cyanobacteria are in the water, and we’ll measure how much iron is inside the cyanobacteria.
That’s easier said than done, because we have to first separate all the “needles” (cyanobacteria) from the “hay” (other cells) and then clean any iron off the outside of the cyanobacteria. Back at Iowa State University, we’ll shoot the individual cells one by one into a flame that incinerates them, which liberates all the iron they contain so we can measure it.

Our scientific hunch, or hypothesis, is that the cyanobacteria that live in the chlorophyll- and iron-rich layer will contain more iron than cyanobacteria that live in the top lake layer. If they do, it will help us establish that greater access to iron is a motive for living in that deeper and dimmer layer.
These experiments won’t tell the whole story of why it took so long for Earth to build up oxygen, but they will help us to understand a piece of it – where oxygen might have been produced and why, and what happened to oxygen in that environment.
Deming Lake is quickly becoming its own attraction for those with a curiosity about what goes on beneath its tranquil surface – and what that might be able to tell us about how new forms of life took hold long ago on Earth.
I thought it very worthwhile to repeat this, plus a real treat at the end of the post!
Scamming in all its forms has only got worse in the last couple of years, since I parted with $9,000 in 2021!
As a direct result of that error, I changed my bank, installed a VPN at home (Proton), changed my email account to ProtonMail, and also changed my calendar (also to Proton).
But I still do not take it as important as it is. I guess because it is not my first thought whenever I come across an unfamiliar email.

My first mistake was not to check the incoming email address. It was mahaliashomakerxhv928@gmail.com
I telephoned the number given and told the person that I wanted to cancel this membership. Indeed that I had never subscribed for this membership in the first place.
I spoke with ‘Adam’. I was then asked to go to a webpage where I filled in a Refund Application Order form. I filled in my details including the refund amount and my bank details: Sort Code & Account Number.
I then submitted the form and imagine my surprise when a few minutes later I was informed that I had received the sum of $10,000. I quickly checked our bank account online and there was the $10,000 credit in our checking account.
My second mistake was me not examining the total in our accounts. I have the facility to show the total funds in our accounts. Why I didn’t do that I can not explain.
Then it was back on the telephone and Adam also was surprised (later I realised that this was a feigned surprise and all part of the scam) and said could I go to the bank and fill in an International Wire Transfer for the amount of $9,500. Adam also said that he would give me the details of the person in Thailand that was to receive the funds, and could I say this was for a medical operation because it would save ‘Norton’ the taxation.
My third mistake was not to discuss this with Jeannie and to assume that it was just a harmless error.
The details came through and I went to our bank in Grants Pass. I got to the bank a little after 09:00. I saw a staff member of the bank and explained what I needed to do. The bank member queried this and said that it sounded like a scam. I lied and said I knew the woman in Thailand and wanted to go ahead. That was what I had been instructed to say.
My fourth mistake was not listening to the woman at the bank. (And I still thought that the ‘Norton’ funds were in my account.)
The International Wire Transfer was completed and I signed it. I also asked the balances on our two accounts. It was about $10,000 less than I expected and I queried it but was told that there had been a transfer from my savings account to my checking account of $10,000 for Norton. I thought that this was still a little low but that I could check it carefully once I got home. I had a thirty-minute window to change my mind.
Mistake number five, a huge mistake, was while at the bank not to ask them carefully to go through all my transactions that day because that would have revealed that the receipt of $10,000 that I had seen online had mysteriously disappeared. Indeed had never been received. That would have enabled me to stop the wire transfer within the thirty-minute window.
I returned home and found out the truth. I had been scammed out of $9,500.
The strange thing was that ‘Adam’ of the billing department of so-called Norton kept ringing me throughout the day to say that the funds would be sent back to me and gave me the details of three wires and that the funds would be back in my bank account on Monday, 9th August!
Later that morning I rang Kevin Dick who manages our investments and told him the tale. He said that there was a huge amount of scamming about and that I should make three phone calls: to the bank and report the fraud; to the Sheriff’s office and report the fraud; and to my insurance company. The first two were done straight away. Kevin also told me to close my bank accounts and amend my email address. Alex, my son, said to use my Proton mail account and straight away I started to make the change.
A person from the humanists group that we belong to said also to inform The Daily Courier.
On Monday morning Ryan of ‘Norton’ called me at 07:15 and said that Adam Prescott was no longer with the firm. Ryan said that their General Manager, Ron Cooper, would call me shortly. Ron did indeed call me and said that they would return the money but that the minimum cheque they could write was $30,000. I was then told that in advance of me receiving the money I would have to pay a small amount to them. At this point I put the phone down for it was clearly a second attempt to steal more funds from me.
Finally we went back to the bank on Monday morning. We were informed that there was never a credit of $10,000 but that a clever switch of the money from one account to another made it look as though the money had been credited. The event had been reported to the bank’s fraud department.
On Tuesday morning, the 10th August, the bank said that as well as our two accounts being locked out from us and that only cheques and cash withdrawals would be honoured for the time being, the fraud department had made the decision to issue us with a ten-day notice to terminate our accounts. In other words, within ten days the bank would no longer want us as customers. Since then I have done much research and found out via the Forbes website that this was more to do with the bank being ultra conservative than anything else. Indeed Kevin said that he had spoken with his IT department and they thought that it was strange that my ex-bank had terminated us so quickly. The IT department thought that the teller at the bank realised that she had been partly culpable.
However the bank did recommend another bank to go to in Grants Pass.
I have since reset my iMac and changed my email address.
It is a most humiliating affair. I have beaten myself up several times over and have at last understood the frame of mind that I had gotten myself into.
To explain that, first of all I thought that I needed to stop the billing urgently and because it was early on a Friday morning thought that the best thing to do was to call immediately.
Secondly, during the call that scammers spoke to me in friendly tones and quietly complimented me on my integrity. I am sure that this ‘spoke’ to my psychological fear of rejection that I have had since I my father died in 1956.
Then in the morning of the 11th August I received a call from a regular contact at the English company who manage my UK SIPP. He wanted to check if I had tried to log on at 09:00 UK time and I replied that there was no way that was me for that UK time was 01:00 Pacific time. There were apparently three attempts to log on. Unsuccessfully as it turned out and my SIPP account is temporarily closed as a result.
The scammers are very thorough in their crooked craft!
Now as of Thursday, the 12th August, we are pretty much out of the grim shadow of this event. We have new accounts at The People’s Bank here in Grants Pass. I have changed my email address and yesterday afternoon I decided that the only safe way of protecting myself was to get another iMac. I was speaking to the sales department of Apple and mentioned the scam and the woman immediately said I should speak with their Technical Support and transferred me. Then I was helped via screen sharing to go through many pages deleting unnecessary files and other stuff. And the helpful woman found another item of malware that was deleted and removed. She spent 54 minutes getting me properly cleaned out and then forwarded an email with all the links for me to do the same process at a later date. It was a superb experience.
So that is it.
Now watch these two YouTube videos. The first is just 5 minutes long and is important to all who use computers and want to be protected against scammers. (NB: This first video is now not included.)
and then watch this slightly longer video from Jim
Be safe! Please!
An addendum dated Saturday, 14th August, at 7am Pacific Time.
Only to say that I also posted my scamming report on Ugly HedgeHog under their General Chit Chat forum. Of the many responses that came in I wanted to post here two of them.
The first from ‘Stanikon’:
Sorry you had to go through this. Your first clue should have been the grammar and phrasing of the original email. That would have given it away. Legitimate companies go to great lengths to make sure their grammar, phrasing and language are correct. I have avoided several scams by paying attention to that so there is some value in being slightly OCD.
and the second from ‘Red6’:
The safest thing to do in these situations is simply not to open the email. I receive on a daily basis, emails telling me that the items I ordered are being shipped, my subscription to something has been renewed etc, etc. 99.9% of these are scams and nothing bad will happen if you just delete them. Older working people often have the fear that there’s a bill out there that has not been paid and they are afraid of getting a bad credit report. So they aggressively try to send someone money for something they cannot even recognize. If it is a true debt, you will be reminded of it several times before any reports are made.
I follow several simple rules in preventing scams. There are many more but this will take care of most of them.
1. Examine the sender’s email address, if you do not recognize it then DO NOT OPEN and DELETE immediately. Most of these scammer’s email addresses will not have the company name in the email address OR it will be combined with other names. Most will not have the .com, .org, etc but will be gmail, Hotmail, or other generic URL. Many of these scammers “broadcast” their emails to everyone on a purchased email list not knowing whether some or valid or not. If you open or reply to these it verifies your email as valid and active and worthy of more attention. Also, if it is an unknown email address, it could be a carrier of a virus or some other bad computer/software infection.
2. If you do get involved with something that does not feel right and you take it to the bank – TRUST THE BANK if they tell you it is suspicious. They see these things every day and develop a feel for them. I received a cashier’s check for something I sold on craigslist. I took it to the bank to deposit and the bank rep immediately recognized the cashier’s check as a fake. She even called the bank the check was supposed to be drawn on and they checked the records and told her that it was counterfeit. You trust your bankers, credit union, etc with your money every day so trust them when they tell you something does not seem right.
3. Scammers know that many older people do NOT like to use credit cards. So a lot of their dealings involve checks, bank transfers, and other forms of older less secure payment methods that older citizens are comfortable with. I NEVER, NEVER send money for something I purchase or order online unless it is through a credit card. In fact, I rarely buy ANYTHING anymore that does not go on the credit card. They are safer, quicker, and easier. If somehow you do get something on your bill that you did not authorize, the credit card company will investigate and go after the person or company that charged you. This is one more safety step that protects the consumer. This does not always apply to debit cards. Debit cards are issued by individual banks or credit unions and some have policies in the fine print that they do NOT have the same policies as the big credit card companies and may not forgive or relieve the user for bad charges made to their debit card.
4. Just do not believe anyone or any company that says they sent you a huge refund or overpayment or some amount of money by mistake. That rarely happens. It is even rarer if they also tell you to return the money to some foreign address, email, or wire transfer. When in doubt, wait for a week or so before you do ANYTHING. If they sent you the check, transfer etc, wait to see if it clears or is valid. We are conditioned by TV and movies that we need to act immediately in situations such as this. This is rarely the case. Take time to see what happens. During this cooling-off period check them out, research the internet to see if others have experienced this scam. It is almost a sure thing that if you are being scammed, others have been also and it has been reported somewhere with law enforcement agencies or on websites on the internet. Check them out before acting. Or better yet, do nothing for a while and most likely they will just go away. Much like the telephone scammers, they make their money on volume, calling as many as possible in the least amount of time. Scammers will not waste time working on you for days, they have thousands of other emails, accounts to call. Remember, they are after the fastest, easiest targets – the low-hanging fruit.
If it is a true mistake or debt you owe then most likely you will receive some official correspondence in regards to the debt. A good example is the IRS and Social Security phone scams in the past couple of years. You get a call from the IRS or Social Security informing you that you may have committed fraud and law enforcement is on their way to arrest you. But if you arrange repayment with their representative, an arrest can be avoided. The IRS and Social Security NEVER take action without first sending several official US Postal letters to you. If you are still inclined to send money to someone in a foreign country then discuss it with your bank and listen.
Hope this helps.

All very sound advice and as relevant today as it was when first published.
Finally, for something completely different; have a look at the recent Hunter’s Moon as featured on YouTube.
For most of us these days old age is part of the scene (and I am classifying old age as being over 70 years). Here are a few facts from the website of the World Health Organization.
Key facts
Worldwide obesity has nearly tripled since 1975.
In 2016, more than 1.9 billion adults, 18 years and older, were overweight. Of these over 650 million were obese.
39% of adults aged 18 years and over were overweight in 2016, and 13% were obese.
Most of the world’s population live in countries where overweight and obesity kills more people than underweight.
39 million children under the age of 5 were overweight or obese in 2020.
Over 340 million children and adolescents aged 5-19 were overweight or obese in 2016.
Obesity is preventable.
What are obesity and overweight Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.
Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person’s weight in kilograms divided by the square of his height in meters (kg/m2).
Adults
For adults, WHO defines overweight and obesity as follows:
overweight is a BMI greater than or equal to 25; and
obesity is a BMI greater than or equal to 30.
BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.
World Health Organisation
This is the link for anyone who wants to use the BMI Calculator.
Now this is not a post about obesity or being overweight. It is a post taken from The Conversation about staying as healthy as one can in one’s older years.

Steep physical decline with age is not inevitable – here’s how strength training can change the trajectory
Raise your hand if you regularly find yourself walking up a flight of stairs. What about carrying heavy bags of groceries? How about picking up your child or grandchild? Most of us would raise our hands to doing at least one of those weekly, or even daily.
As people age, it can become more and more difficult to perform some physical tasks, even those that are normal activities of daily living. However, prioritizing physical fitness and health as you get older can help you go through your normal day-to-day routine without feeling physically exhausted at the end of the day.
It can also help you continue to have special memories with your family and loved ones that you might not have been able to have if you weren’t physically active. For example, I ran two half-marathons with my dad when he was in his 60s!
I am an exercise physiologist who studies how people can use resistance training to improve human performance, whether it be in sports and other recreational settings, in everyday life, or both. I am also a certified strength and conditioning specialist. My career has given me the opportunity to design exercise programs for kids, college athletes and elderly adults.
Staying physically active as you get older doesn’t need to include running a half-marathon or trying to be a bodybuilder; it could be as simple as trying to get through the day without feeling winded after you go up a flight of stairs. Although our muscles naturally get weaker as we age, there are ways we can combat that to help improve quality of life as we get older.

Muscle loss and chronic disease
One of the most important parts of exercise programming, no matter who I am working with, is proper resistance training to build muscle strength. Some amount of age-related loss of muscle function is normal and inevitable. But by incorporating resistance training that is appropriate and safe at any ability level, you can slow down the rate of decline and even prevent some loss of muscle function.
In one of our team’s previous studies, we saw that otherwise healthy individuals with sarcopenia had issues delivering vital nutrients to muscle. This could lead to greater likelihood of various diseases, such as Type 2 diabetes, and slow down recovery from exercise.
Recent estimates suggest that sarcopenia affects 10% to 16% of the elderly population worldwide. But even if a person doesn’t have clinically diagnosed sarcopenia, they may still have some of the underlying symptoms that, if not dealt with, could lead to sarcopenia.
Strength training is key
So the question is, what can be done to reverse this decline?
Recent evidence suggests that one of the key factors leading to sarcopenia is low muscle strength. In other words, combating or reversing sarcopenia, or both, may be best done with a proper resistance-training program that prioritizes improving strength. In fact, the decline in muscle strength seems to occur at a much faster rate than the decline in muscle size, underscoring the importance of proper strength training as people age.
Typical age-related changes in muscle strength and size with and without strength training. Zachary Gillen
Continuing to regularly strength train with moderate to heavy weights has been shown to be not only effective at combating the symptoms of sarcopenia but also very safe when done properly. The best way to make sure you are strength training properly is to seek out guidance from a qualified individual such as a personal trainer or strength and conditioning specialist.
Despite the clear benefits of strength training, it’s been shown that only about 13% of Americans age 50 and older do some form of strength training at least twice a week.
Finding what works for you
So how does a person properly strength train as they age?
The National Strength and Conditioning Association, a leading organization in advancing strength and conditioning around the world, states that for older adults, two to three days per week of strength training can be incredibly helpful for maintaining healthy muscle and bone and combating a number of chronic conditions.
The organization recommends that these workouts involve one to two exercises involving multiple joints per major muscle group, with six to 12 repetitions per set. These are done at an intensity of 50% to 85% of what’s known as one-repetition maximum – the most weight you could handle for a single repetition – with the exception of body weight exercises that use one’s own body weight as the resistance, such as pushups.
I would also recommend resting for about two to three minutes between sets, or even up to five minutes if the set was challenging. For older adults, particularly those age 60 and older, the National Strength and Conditioning Association guidelines suggest that a program like this be performed two to three days per week, with 24 to 48 hours between sessions.
An example of a strength training routine for older adults based on the National Strength and Conditioning Association guidelines
There are a great variety of exercises that could be done interchangeably in a strength training program like this.
The guidelines above are only one example out of many options, but they provide a framework that you can use to build your own program. However, I would highly recommend seeking out a professional in the field to give specific exercise programming advice that can be tailored to your own needs and goals as you age.
Following such a program would give your muscles an excellent stimulus to enhance strength, while also allowing enough recovery, a very important consideration as people age. You might think it looks like a huge time commitment, but an exercise routine like this can be done in less than an hour. This means that in less than three hours of strength training per week you can help improve your muscle health and reduce the risk of getting sarcopenia and associated health issues.
It’s also important to note that there is no one right way to do resistance training, and it needn’t involve traditional weight equipment. Group classes like Pilates and yoga or those that involve circuit training and work with resistance bands can all produce similar results. The key is to get out and exercise regularly, whatever that entails.
My wife, Jean, was diagnosed with Parkinson’s Disease (PD) in December, 2015. Many of you know that.
Fortunately at our local Club Northwest there was a group of PD sufferers who twice a week held a ‘Rock Steady Class’ under the instruction of a professional coach; Jean joined the group. It was a brilliant move for Jean and she gets a huge amount of care from being with them.
Luckily for me having to drive Jean into Club Northwest it made sense for me to sign up to a fitness class at the same time so I am put through a regular fitness routine under the coaching of Bruce. Plus I try and go bike riding three times a week.
In other words, we both try and stay as fit as we can.
