A Good Samaritan was hiking a narrow, slippery trail on Lookout Mountain in Phoenix, Arizona, and was very focused on his hike until something caught his eye. He was about half a mile up the mountain and a little off the beaten path when he caught a glimpse of light reflecting off of something — and was shocked to realize it was a pair of amber eyes.
The eyes belonged to a very scared dog huddled up in a tiny hole in the side of the mountain. She was completely blending in with her surroundings, and if she hadn’t had such piercing eyes, the hiker may not have noticed her. He had no idea how she’d managed to get up there, but it was clear that she’d been stuck for a while and might not be able to last much longer.
The Good Samaritan quickly contacted the Arizona Humane Society (AHS), who sent two emergency animal medical technicians, Tracey Miiller and Ruthie Jesus, out to help while he waited with the pup until they arrived. The dog was definitely scared but seemed open to getting help.
“This Good Samaritan waited probably almost two hours, and then we found this incredible dog, who incidentally is literally the same color as the dirt,” Jesus said in a press release. “She blends in so much, the complainant told us that he wanted to call her Bright Eyes because when he hiked past her, that was literally the only thing he saw was her amber bright eyes staring back at him.”
After a quick and careful assessment on the side of the mountain, the technicians determined that Bright Eyes was dangerously dehydrated with cut-up paws and a wound on her rear end.
“She was really sweet and letting me pet her head, but she absolutely did not want to come out of that den, so I kind of had to just sort of pull her out,” Jesus said.
She was definitely too weak to walk with her rescuers down the mountain, so the technicians took turns carrying her until they reached the ambulance. Bright Eyes was calm the whole time, so grateful to finally be safe.
“She actually really just relaxed and seemed to enjoy being carried down the mountain,” Jesus said. “But it was a very teeny-tiny rocky trail that was pretty slick, and so Tracey and I took turns carrying her down the mountain, and she was just an absolute angel. She knew we were getting her to safety.”
It’s still a mystery as to how or why Bright Eyes ended up on the mountain in the first place, but the important thing is someone found her and now she’s getting the care she needs.
“We were so elated to be able to get her,” Jesus said. “She was just so dehydrated. I think she’d probably been up there several days and that was probably her last day, and this Good Samaritan really just saved her life.”

Frankly, there’s nothing more to add to this account. For it captured all that so many people do for dogs.
Although I was born in London in 1944, as a result of an affair between my father and mother, my father had two daughters with his wife, Maud, and Rhona and Corinne, for they were their names, took me under their wing. In the 50s Maud, Rhona and Corinne all moved to Devon and I started going regularly to Totnes. When I started driving I usually stopped for a break close by Stonehenge so the site has a special interest to me.
So when I saw this article in The Conversation it had to be shared.

Stonehenge may have aligned with the Moon as well as the Sun
When it comes to its connection to the sky, Stonehenge is best known for its solar alignments. Every midsummer’s night tens of thousands of people gather at Stonehenge to celebrate and witness the rising Sun in alignment with the Heel stone standing outside of the circle. Six months later a smaller crowd congregates around the Heel stone to witness the midwinter Sun setting within the stone circle.
But a hypothesis has been around for 60 years that part of Stonehenge also aligns with moonrise and moonset at what is called a major lunar standstill. Although a correlation between the layout of certain stones and the major lunar standstill has been known about for several decades, no one has systematically observed and recorded the phenomenon at Stonehenge.
This is what we are aiming to do in a project bringing together archaeologists, astronomers and photographers from English Heritage, Oxford, Leicester and Bournemouth universities as well as the Royal Astronomical Society.
There is now an abundance of archaeological evidence that indicates the solar alignment was part of the architectural design of Stonehenge. Around 2500 BC, the people who put up the large stones and dug an avenue into the chalk seemed to want to cement the solstice axis into the architecture of Stonehenge.
Archaeological evidence from nearby Durrington Walls, the place where scientists believe the ancient people who visited Stonehenge stayed, indicates that of the two solstices it was the midwinter one that drew the largest crowd.
But Stonehenge includes other elements, such as 56 pits arranged in a circle, an earthwork bank and ditch, and other smaller features such as the four station stones. These are four sarsen stones, a form of silicified sandstone common in Wiltshire, that were carefully placed to form an almost exact rectangle encompassing the stone circle.
Only two of these stones are still there, and they pale in comparison to their larger counterparts as they are only a few feet high. So what could their purpose be?

Lunar standstill
The rectangle that they form is not just any rectangle. The shorter sides are parallel to the main axis of the stone circle and this may be a clue as to their purpose. The longer sides of the rectangle skirt the outside of the stone circle.
It is these longer sides that are thought to align with the major lunar standstill. If you marked the position of moonrise (or set) over the course of a month you would see that it moves between two points on the horizon. These southern and northern limits of moonrise (or set) change on a cycle of 18.6 years between a minimum and a maximum range – the so-called minor and major lunar standstills, respectively.
The major lunar standstill is a period of about one and a half to two years when the northernmost and southernmost moonrises (or sets) are furthest apart. When this happens the Moon rises (and sets) outside the range of sunrises and sets, which may have imbued this celestial phenomenon with meaning and significance.

The strongest evidence we have for people marking the major lunar standstill comes from the US southwest. The Great House of Chimney Rock, a multi-level complex built by the ancestral Pueblo people in the San Juan National Forest, Colorado, more than 1,000 years ago.
It lies on a ridge that ends at a natural formation of twin rock pillars – an area that has cultural significance to more than 26 native American tribal nations. From the vantage point of the Great House, the Sun will never rise in the gap between the pillars.
However, during a major standstill the Moon does rise between them in awe-inspiring fashion. Excavations unearthed preserved wood that meant researchers could date to the year episodes of construction of the Great House.
Of six cutting dates, four correspond to major lunar standstill years between the years AD1018 and AD1093, indicating that the site was renewed, maintained or expanded on consecutive major standstills.
Returning to southern England, archaeologists think there is a connection between the major lunar standstill and the earliest construction phase of Stonehenge (3000-2500 BC), before the sarsen stones were brought in.
Several sets of cremated human remains from this phase of construction were found in the southeastern part of the monument in the general direction of the southernmost major standstill moonrise, where three timber posts were also set into the bank. It is possible that there was an early connection between the site of Stonehenge and the Moon, which was later emphasised when the station stone rectangle was built.
The major lunar standstill hypothesis, however, raises more questions than it answers. We don’t know if the lunar alignments of the station stones were symbolic or whether people were meant to observe the Moon through them. Neither do we know which phases of the Moon would be more dramatic to witness.
A search for answers
In our upcoming work, we will be trying to answer the questions the major lunar standstill hypothesis raises. It’s unclear whether the Moon would have been strong enough to cast shadows and how they would have interacted with the other stones. We will also need to check whether the alignments can still be seen today or if they are blocked by woods, traffic and other features.
The Moon will align with the station stone rectangle twice a month from about February 2024 to November 2025, giving us plenty of opportunities to observe this phenomenon in different seasons and phases of the Moon.
To bring our research to life, English Heritage will livestream the southernmost Moonrise in June 2024, and host a series of events throughout the year, including talks, a pop-up planetarium, stargazing and storytelling sessions.
Across the Atlantic, our partners at the US Forest Service are developing educational materials about the major lunar standstill at Chimney Rock National Monument. This collaboration will result in events showcasing and debating the lunar alignments at both Stonehenge and at Chimney Rock.
It is about Whale songs and is just a fabulous sound!
Last Friday there was an item on the BBC about whale song. It appears I can publish the article for you all. It is my choice over my regular Sunday Picture Parade. I hope you agree! Update: The track just 26 seconds long cannot be reproduced in this post.

Whale song mystery solved by scientists
21 February 2024, By Helen Briggs and Victoria Gill,Science correspondents, BBC News
Humpback whale breaching near Bering Island, Kamchatka, Russia – Olga Filatova, University of Southern Denmark
Scientists have worked out how some of the largest whales in the ocean produce their haunting and complex songs.
Humpbacks and other baleen whales have evolved a specialised “voice box” that enables them to sing underwater.
The discovery, published in the journal Nature, has also revealed why the noise we make in the ocean is so disruptive for these ocean giants.
Whale song is restricted to a narrow frequency that overlaps with the noise produced by ships. “Sound is absolutely crucial for their survival, because it’s the only way they can find each other to mate in the ocean,” explained Prof Coen Elemans, of the University of Southern Denmark, who led the study.
“[These are some] of the most enigmatic animals that ever lived on the planet,” he told BBC News. “They are amongst the biggest animals, they’re smart and they’re highly social.”
Humpback whale song (For whatever reason the track cannot be listened to on this blog. That is a great shame as the song is magnificent. So please go to the BBC website for this; the link is https://www.bbc.com/news/science-environment-68358414 )
Baleen whales are a group of 14 species, including the blue, humpback, right, minke and gray whale. Instead of teeth, the animals have plates of what is called baleen, through which they sieve huge mouthfuls of tiny creatures from the water.
Exactly how they produce complex, often haunting songs has been a mystery until now. Prof Elemans said it was “super-exciting” to have figured it out.

He and his colleagues carried out experiments using larynxes, or “voice boxes”, that had been carefully removed from three carcasses of stranded whales – a minke, a humpback and a sei whale. They then blew air through the massive structures to produce the sound.
In humans, our voices come from vibrations when air passes over structures called vocal folds in our throat. Baleen whales, instead, have a large U-shaped structure with a cushion of fat at the top of the larynx.
This vocal anatomy allows the animals to sing by recycling air, and it prevents water from being inhaled.

The researchers produced computer models of the sounds and showed that baleen whale song is restricted to a narrow frequency which overlaps with noise produced by shipping vessels.
“They cannot simply choose to, for example, sing higher to avoid the noise we make in the ocean,” explained Prof Elemans.
His study demonstrated how our ocean noise could prevent whales from communicating over long distances. That knowledge could be vital for the conservation of humpbacks, blue whales and other endangered giants of the sea.
It also provides insight into questions that researchers have been asking for decades about these eerie songs, which some sailors used to attribute to ghosts or mythical sea creatures.
Whale communication expert Dr Kate Stafford, from Oregon State University, called the study “groundbreaking”.
“The production and reception of sound is the most important sense for marine mammals, so any studies that elucidate how they make sounds has the potential to move the field forward,” she told BBC News.

The research also paints an evolutionary picture – of how the ancestors of whales returned to the oceans from the land, and the adaptations that made it possible to communicate underwater.
The way so-called toothed whales produce sound is better understood, because the animals are easier to study. These marine mammals, which include dolphins, orcas, sperm whales and porpoises, blow air through a special structure in their nasal passages.
Dr Ellen Garland, from the Sea Mammal Research Unit at the University of St Andrews, said: “I’ve always wondered exactly how baleen whales – especially humpbacks, which my research is focused on – actually produce the variety of sounds they do.
“Studying large whales is extremely challenging at the best of times, but trying to uncover how they produce sound when you may not even be able to see them underwater while vocalising is an added level of difficulty, so these researchers have been very creative.”
Dr Stafford added that the mammals’ ability to make such complex vocal signals was “remarkable” and highlighted “how special these animals are”.

There! I do hope you all agree that this was very worthwhile. Plus, you all got to listen to those twenty-six seconds of the very beautiful sound.
As 99% of you know, Jean, my wife, has Parkinson’s Disease. One of the characteristics of the disease is the effect it has on sleeping; Jean frequently has a bad night. Plus, our two dogs, Cleopatra and Oliver sleep in the bedroom on dog beds.
But if I was on my own I would find it difficult not to encourage our dogs to sleep on our double bed. That’s my assessment, at least! Over to The Conversation on the topic.

Could sharing a bedroom with your pets be keeping you from getting a good night’s sleep?
Sleeping with your dog in the same room could be negatively affecting your sleep quality, according to my team’s recently published research in Scientific Reports.
We recruited a nationally representative sample of more than 1,500 American adults who completed questionnaires assessing their sleep habits. Overall, about half of the participants reported co-sleeping with pets – defined in our study as sleeping in the same room with your pet for at least part of the night.
Next, our research team compared the sleep habits of people who did and didn’t co-sleep with pets. Our analyses revealed that participants who co-slept with pets had poorer sleep quality and more insomnia symptoms than those who did not. These findings persisted even after accounting for demographic differences between these groups. When considering pet type, we found evidence for a negative effect on sleep when co-sleeping with dogs but no evidence for a negative effect on sleep when co-sleeping with cats.
Surprisingly, 93% of people in our study who co-slept with their pets believed that their pets had either a positive or neutral overall effect on their sleep. Although more research is needed, these findings could suggest that most people are unaware of the potential negative effects their pets may have on their sleep.
However, our study fills an important knowledge gap by indicating that co-sleeping with pets can affect sleep quality. Good sleep is a pillar of health and wellness. Even though pets may have an overall positive effect on mental health, it is possible that some of this benefit may be undermined if they are also causing you to lose sleep at night.
Although some people report that co-sleeping with their pets can provide them with a sense of comfort or intimacy, it is important for people sharing a bedroom with their pets to be aware of their potential to serve as a source of nighttime noise, heat or movement that can disrupt your ability to fall or stay asleep.
What still isn’t known
Survey-based studies like ours are unable to prove that co-sleeping with pets causes disrupted sleep, although there is some evidence suggesting that this could be the case.
It probably isn’t realistic for most people to just stop co-sleeping with their pets. So, what should someone do to improve their sleep if they already share a bed with their pets?
Some expert tips include choosing a mattress that is large enough for you and your pets, washing and changing your bedding regularly, and establishing and maintaining a consistent bedtime routine with your pets. Further research is needed to identify more specific habits and routines that pet owners can adopt to ensure a good night’s sleep when sharing the bedroom with their pets.
The Research Brief is a short take about interesting academic work.
Coming back to Jean and me at least we have a pretty regular routine with us going to our bedroom around 7pm to 8pm. In the morning over our daily coffees I always ask Jean what sort of night she had. Yesterday morning Jean replied that she had had a poor night. My judgement is that Jean has roughly one in two poor nights.
A riveting history of counting and calculating from the time of the cave dwellers to the late twentieth century, The Universal History of Numbers is the first complete account of the invention and evolution of numbers the world over. As different cultures around the globe struggled with problems of harvests, constructing buildings, educating their citizens, and exploring the wonders of science, each civilization created its own unique and wonderful mathematical system.
Dubbed the “Indiana Jones of numbers,” Georges Ifrah traveled all over the world for ten years to uncover the little-known details of this amazing story. From India to China, and from Egypt to Chile, Ifrah talked to mathematicians, historians, archaeologists, and philosophers. He deciphered ancient writing on crumbling walls; scrutinized stones, tools, cylinders, and cones; and examined carved bones, elaborately knotted counting strings, and X-rays of the contents of never-opened ancient clay accounting balls. Conveying all the excitement and joy of the process of discovery, Ifrah writes in a delightful storytelling style, recounting a plethora of intriguing and amusing anecdotes along the way.
Now to that article on The Conversation.

From thousands to millions to billions to trillions to quadrillions and beyond: Do numbers ever end?
Why don’t numbers end? – Reyhane, age 7, Tehran, Iran
Here’s a game: Ask a friend to give you any number and you’ll return one that’s bigger. Just add “1” to whatever number they come up with and you’re sure to win.
The reason is that numbers go on forever. There is no highest number. But why? As a professor of mathematics, I can help you find an answer.
First, you need to understand what numbers are and where they come from. You learned about numbers because they enabled you to count. Early humans had similar needs – whether to count animals killed in a hunt or keep track of how many days had passed. That’s why they invented numbers.
But back then, numbers were quite limited and had a very simple form. Often, the “numbers” were just notches on a bone, going up to a couple hundred at most.
How numbers evolved throughout the centuries.
When numbers got bigger
As time went on, people’s needs grew. Herds of livestock had to be counted, goods and services traded, and measurements made for buildings and navigation. This led to the invention of larger numbers and better ways of representing them.
About 5,000 years ago, the Egyptians began using symbols for various numbers, with a final symbol for one million. Since they didn’t usually encounter bigger quantities, they also used this same final symbol to depict “many.”
The Greeks, starting with Pythagoras, were the first to study numbers for their own sake, rather than viewing them as just counting tools. As someone who’s written a book on the importance of numbers, I can’t emphasize enough how crucial this step was for humanity.
But there was a problem. Although the Greeks could mentally think of very large numbers, they had difficulty writing them down. This was because they did not know about the number 0.
Think of how important zero is in expressing big numbers. You can start with 1, then add more and more zeroes at the end to quickly get numbers like a million – 1,000,000, or 1 followed by six zeros – or a billion, with nine zeros, or a trillion, 12 zeros.
This brief history makes clear that numbers were developed over thousands of years. And though the Egyptians didn’t have much use for a million, we certainly do. Economists will tell you that government expenditures are commonly measured in millions of dollars.
Also, science has taken us to a point where we need even larger numbers. For instance, there are about 100 billion stars in our galaxy – or 100,000,000,000 – and the number of atoms in our universe may be as high as 1 followed by 82 zeros.
Don’t worry if you find it hard to picture such big numbers. It’s fine to just think of them as “many,” much like the Egyptians treated numbers over a million. These examples point to one reason why numbers must continue endlessly. If we had a maximum, some new use or discovery would surely make us exceed it.
The symbols of math include +, -, x and =.
Exceptions to the rule
But under certain circumstances, sometimes numbers do have a maximum because people design them that way for a practical purpose.
A good example is a clock – or clock arithmetic, where we use only the numbers 1 through 12. There is no 13 o’clock, because after 12 o’clock we just go back to 1 o’clock again. If you played the “bigger number” game with a friend in clock arithmetic, you’d lose if they chose the number 12.
Since numbers are a human invention, how do we construct them so they continue without end? Mathematicians started looking at this question starting in the early 1900s. What they came up with was based on two assumptions: that 0 is the starting number, and when you add 1 to any number you always get a new number.
These assumptions immediately give us the list of counting numbers: 0 + 1 = 1, 1 + 1 = 2, 2 + 1 = 3, and so on, a progression that continues without end.
You might wonder why these two rules are assumptions. The reason for the first one is that we don’t really know how to define the number 0. For example: Is “0” the same as “nothing,” and if so, what exactly is meant by “nothing”?
The second might seem even more strange. After all, we can easily show that adding 1 to 2 gives us the new number 3, just like adding 1 to 2002 gives us the new number 2003.
But notice that we’re saying this has to hold for any number. We can’t very well verify this for every single case, since there are going to be an endless number of cases. As humans who can perform only a limited number of steps, we have to be careful anytime we make claims about an endless process. And mathematicians, in particular, refuse to take anything for granted.
Here, then, is the answer to why numbers don’t end: It’s because of the way in which we define them.
Now, the negative numbers
How do the negative numbers -1, -2, -3 and more fit into all this? Historically, people were very suspicious about such numbers, since it’s hard to picture a “minus one” apple or orange. As late as 1796, math textbooks warned against using negatives.
The negatives were created to address a calculation issue. The positive numbers are fine when you’re adding them together. But when you get to subtraction, they can’t handle differences like 1 minus 2, or 2 minus 4. If you want to be able to subtract numbers at will, you need negative numbers too.
A simple way to create negatives is to imagine all the numbers – 0, 1, 2, 3 and the rest – drawn equally spaced on a straight line. Now imagine a mirror placed at 0. Then define -1 to be the reflection of +1 on the line, -2 to be the reflection of +2, and so on. You’ll end up with all the negative numbers this way.
As a bonus, you’ll also know that since there are just as many negatives as there are positives, the negative numbers must also go on without end!
Hello, curious kids! Do you have a question you’d like an expert to answer? Ask an adult to send your question to CuriousKidsUS@theconversation.com. Please tell us your name, age and the city where you live.
And since curiosity has no age limit – adults, let us know what you’re wondering, too. We won’t be able to answer every question, but we will do our best.
This article was written for those a great deal younger than I am. But, to be honest, it is a fascinating account of something so utterly basic to humans and human cognition.
I shall be 80 in November and I find myself thinking about death more often than I did a few years ago. As an example of how my mind has changed, yesterday I was contemplating renewing my subscription to the Free Inquiry magazine and wondering if I should renew it for two or three years? In other words will I still be alive in three years time? Silly but it is the truth. And that is not taking into account that I go to the Club Northwest two days a week and try and bike ride another two or three times a week.
Then let us not get into the topic of whether I will die before Jean or the reverse. That is an enormous subject and, thank goodness, where we live in Oregon one has the choice to die: “Two states, Oregon and Washington, currently have statutes providing a procedure for a terminally ill patient to request medication to end his or her life. These laws are sometimes referred to as “death with dignity” or “physician-assisted suicide” laws.“
All of which is an introduction to a recent article published in The Conversation that I republish below:

Loneliness can kill, and new research shows middle-aged Americans are particularly vulnerable
Middle-aged Americans are lonelier than their European counterparts. That’s the key finding of my team’s recent study, published in American Psychologist.
Our study identified a trend that has been evolving for multiple generations, and affects both baby boomers and Gen Xers. Middle-aged adults in England and Mediterranean Europe are not that far behind the U.S. In contrast, middle-aged adults in continental and Nordic Europe reported the lowest levels of loneliness and stability over time.
We used survey data drawn from over 53,000 middle-aged adults from the U.S. and 13 European nations from 2002 to 2020. We tracked their reported changes in loneliness every two years across the midlife years of 45 to 65. This span provided us data from the so-called silent generation of people born between 1937 and 1945; baby boomers, born between 1946 and 1964; and members of Generation X, born between 1965 and 1974.
Our study makes clear that middle-aged Americans today are experiencing more loneliness than their peers in European nations. This coincides with existing evidence that mortality rates are rising for working-age adults in the U.S.
We focused on middle-aged adults for several reasons. Middle-aged adults form the backbone of society by constituting a majority of the workforce. But they also face increasing challenges today, notably greater demands for support from both their aging parents and their children.
Loneliness is considered a global public health issue. The U.S. surgeon general released an advisory report in 2023 documenting an epidemic of loneliness and a pressing need to increase social connection. Other nations, such as the U.K.and Japan, have appointed ministers of loneliness to ensure relationships and loneliness are considered in policymaking.
You can be lonely even when surrounded by people.
What still isn’t known
Why are middle-aged Americans exceptional when it comes to loneliness and poorer overall mental and physical health?
We did not directly test this in our study, but in the future we hope to zero in on the factors driving these trends. We think that the loneliness Americans are reporting compared to peer nations comes down to limited social safety nets and to cultural norms that prioritize individualism over community.
Individualization carries psychological costs, such as reductions in social connections and support structures, which are correlates of loneliness. Relative to the other nations in our study, Americans have a higher tendency to relocate, which is associated with weak social and community ties.
One of the reasons why we chose countries from across Europe is that they differ dramatically from the U.S. when it comes to social and economic opportunities and social safety nets. Social and economic inequalities likely increase one’s loneliness through undermining one’s ability to meet basic needs. Generous family and work policies likely lessen midlife loneliness through reducing financial pressures and work-family conflict, as well as addressing health and gender inequities.
Our findings on loneliness in conjunction with previous studies on life expectancy, health, well-being and cognition suggest that being middle-aged in America is a risk factor for poor mental and physical health outcomes.
The Research Brief is a short take on interesting academic work.
And on yesterday afternoon, the Sunday, I went for a bike ride of 22 miles. I loved the ride especially as I listened to music all the way; I have a portable speaker that clips near the front handlebars and plays tracks from my iPhone.
Then there was an article in March from the University of Bristol: “Happiness can be learnt, but we have to work at it – study finds.“
It reads:
Press release issued: 11 March 2024
We can learn to be happy, but only get lasting benefits if we keep practising, a first-of-its-kind study has revealed.
The team behind the University of Bristol’s ‘Science of Happiness’ course had already discovered that teaching students the latest scientific studies on happiness created a marked improvement in their wellbeing.
But their latest study found that these wellbeing boosts are short-lived unless the evidence-informed habits learnt on the course – such as gratitude, exercise, meditation or journaling – are kept up over the long-term.
Senior author Professor Bruce Hood said: “It’s like going to the gym – we can’t expect to do one class and be fit forever. Just as with physical health, we have to continuously work on our mental health, otherwise the improvements are temporary.”
Launched in 2018, the University of Bristol’s Science of Happiness course was the first of its kind in the UK. It involves no exams or coursework, and teaches students what the latest peer-reviewed studies in psychology and neuroscience say really makes us happy.
Students who took the course reported a 10 to 15% improvement in wellbeing. But only those who continued implementing the course learnings maintained that improved wellbeing when they were surveyed again two years on.
Published in the journal Higher Education, it is the first to track wellbeing of students on a happiness course long after they have left the course.
Professor Hood said: “This study shows that just doing a course – be that at the gym, a meditation retreat or on an evidence-based happiness course like ours – is just the start: you must commit to using what you learn on a regular basis.
“Much of what we teach revolves around positive psychology interventions that divert your attention away from yourself, by helping others, being with friends, gratitude or meditating.
“This is the opposite of the current ‘selfcare’ doctrine, but countless studies have shown that getting out of our own heads helps gets us away from negative ruminations which can be the basis of so many mental health problems.”
Professor Hood has distilled the Science of Happiness course into a new book, out on March 10. ‘The Science of Happiness: Seven Lessons for Living Well’ reveals an evidence-informed roadmap to better wellbeing.
The other paper authors are fellow University of Bristol academics Catherine Hobbs and Sarah Jelbert, and Laurie R Santos, a Yale academic whose course inspired Bristol’s Science of Happiness course.
The challenge in deciding what is best for our forests.
As a great many of you already know, we live in a rural area in Southern Oregon. It is a beautiful place and we look out to the East upon Mount Sexton. But locally a great many houses are built on rural sites with the local forest just yards away.
In the U.S., wildland firefighters are able to stop about 98% of all wildfires before the fires have burned even 100 acres. That may seem comforting, but decades of quickly suppressing fires has had unintended consequences.
However, fuel accumulation isn’t the only consequence of fire suppression.
Fire suppression also disproportionately reduces certain types of fire. In a new study, my colleagues and I show how this effect, known as the suppression bias, compounds the impacts of fuel accumulation and climate change.
What happened to all the low-intensity fires?
Most wildfires are low-intensity. They ignite when conditions aren’t too dry or windy, and they can often be quickly extinguished.
The 2% of fires that escape suppression are those that are more extreme and much harder to fight. They account for about 98% of the burned area in a typical year.
The author and colleagues discuss changing wildfire in Montana and Idaho’s Bitterroot Mountains. By Mark Kreider.
In our study, we used a fire modeling simulation to explore the effects of the fire suppression bias and see how they compared to the effects of global warming and fuel accumulation alone.
Fuel accumulation and global warming both inherently make fires more severe. But over thousands of simulated fires, we found that allowing forests to burn only under the very worst conditions increased fire severity by the same amount as more than a century’s worth of fuel accumulation or 21st-century climate change.
The suppression bias also changes the way plants and animals interact with fire.
By removing low-intensity fires, humans may be changing the course of evolution. Without exposure to low-intensity fires, species can lose traits crucial for surviving and recovering from such events.
In contrast, low-intensity fires free up space and resources for new growth, while still retaining living trees and other biological legacies that support seedlings in their vulnerable initial years.
By quickly putting out low-intensity fires and allowing only extreme fires to burn, conventional suppression reduces the opportunities for climate-adapted plants to establish and help ecosystems adjust to changes like global warming.

Suppression makes burned area increase faster
As the climate becomes hotter and drier, more area is burning in wildfires. If suppression removes fire, it should help slow this increase, right?
In fact, we found it does just the opposite.
We found that while conventional suppression led to less total area burning, the yearly burned area increased more than three times faster under conventional suppression than under less aggressive suppression efforts. The amount of area burned doubled every 14 years with conventional fire suppression under simulated climate change, instead of every 44 years when low- and moderate-intensity fires were allowed to burn. That raises concerns for how quickly people and ecosystems will have to adapt to extreme fires in the future.
With conventional fire suppression, the average fire size will increase faster as the planet warms than it would under a less aggressive approach. Mark Kreider
The fact that the amount of area burned is increasing is undoubtedly driven by climate change. But our study shows that the rate of this increase may also be a result of conventional fire management.
The near total suppression of fires over the last century means that even a little additional fire in a more fire-prone future can create big changes. As climate change continues to fuel more fires, the relative increase in area burned will be much bigger.
To address the wildfire crisis, fire managers can be less aggressive in suppressing low- and moderate-intensity fires when it is safe to do so. They can also increase the use of prescribed fire and cultural burning to clear away brush and other fuel for fires.
These low-intensity fires will not only reduce the risk of future extreme fires, but they also will create conditions that favor the establishment of species better suited to the changing climate, thereby helping ecosystems adapt to global warming.
Coexisting with wildfire requires developing technologies and approaches that enable the safe management of wildfires under moderate burning conditions. Our study shows that this may be just as necessary as other interventions, such as reducing the number of fires unintentionally started by human activities and mitigating climate change.
The article makes a great deal of sense and presents a solution that may not be our first thought. But especially the message is fundamentally important, and please watch the video because it very clearly presents the benefits of the solution.
So we want more low-intensity fires! Please! Or to say it another way, we want more prescribed fires.
I was born in London in November, 1944. Exactly six months before the Second World War ended in April, 1945.
Thus it was of great interest to me that yesterday Jean and I listened to a BBC Radio 4 programme about the letters that were exchanged between two great Jewish men: Einstein and Freud, in 1932. The programme was called Why War? The Einstein-Freud Letters.
The programme ends with offering the listener a fundamental choice, which I won’t spoil for you now. But to me it is an extension of my post (or Patrice’s post) that I published recently on March 19th.
I believe, and hope, you can listen to it by clicking on this link. Here also is the text that is at that link:
In 1932 the world-famous physicist Albert Einstein wrote a public letter to the founder of psychoanalysis, Sigmund Freud. Einstein, a keen advocate of the League of Nations and peace campaigner, asked Freud if he thought war and aggression was forever tied to human psychology and the course of international relations: could we ever secure a lasting world peace?
Einstein’s letter is deeply prescient, as is Freud’s extraordinary response. The exchange was titled ‘Why War?’. The two thinkers explore the nature of war and peace in politics and in all human life; they think about human nature, the history of warfare and human aggression and the hope represented by the foundation of the League of Nations (precursor to the UN) and its promise of global security and a new architecture of international law.
At the time of their exchange, Freud is in the last great phase of his career and has already introduced psychoanalysis into the field of politics and society. Einstein, the younger of the two, is using his huge international profile as a physicist for political and pacifist intervention.
For Einstein, future world security means a shared moral understanding across the global order – that humankind rise above the ‘state of nature’ never to devolve into total war again. He wrote to Freud, as ‘a citizen of the world…immune to nationalist bias…I greatly admire your passion to ascertain the truth. You have shown how the aggressive and destructive instincts are bound up in the human psyche with those of love and the lust for life. At the same time, you make manifest your devotion to the goal of liberation from the evils of war…’ Is it possible, Einstein asks Freud, to make us ‘proof against the psychoses of hate and destructiveness?’. Freud’s answer is fascinating and quite unexpected.
The exchange of letters was sponsored by the International Institute of Intellectual Cooperation, an organisation promoting global security by using prominent thinkers, drawing on multiple fields of knowledge (from science to psychology, politics and law) to achieve a new language for international peace, following the lessons learned from the Great War of 1914-18.
But even as Einstein wrote to Freud in the summer of 1932, the Nazi party became the largest political party in the German Reichstag. Both men felt a sense of apprehension about what was coming; both were pacifist, both Jewish, both would be driven into exile (both Einsteinian physics and Freudian psychoanalysis were denounced by the new regime). The letters were finally published in 1933 when Hitler came to power, suppressed in Germany, and as a result never achieved the circulation intended for them.
Featuring readings from the Einstein–Freud letters and contributions from historians of warfare and psychoanalysis, war journalism and global security, this feature showcases the little-known exchange between two of the 20th century’s greatest thinkers, ‘Why War?’ – a question just as relevant in today’s world.
Contributors include historian of war and peace Margaret MacMillan, BBC chief international correspondent Lyse Doucet, defence and security expert Mark Galeotti, historian of international relations Patrick O Cohrs, author Lisa Appignanesi, who has written on Freud and the history of psychoanalysis, and Faisal Devji, historian of conflict and political violence in India and the Middle East.
Readings are by Elliot Levey (Einstein) and Henry Goodman (Freud)
At first sight, the above title goes without saying. But then one quickly realises that not everyone, by far, has the circumstances that are ideal for dogs.
Thus, it is an important guest post from Penny.

Canine Contentment: Effortless Ways to Please Your Pooch
Enhancing your dog’s quality of life goes beyond just fulfilling their basic needs. It’s about creating a fulfilling environment that nurtures both their physical and mental well-being, ensuring they lead a happy and healthy life. By adopting a few straightforward strategies, you can make a significant impact on your furry companion’s daily life. In today’s post on the Learning From Dogs blog, we delve into practices that promise to elevate your dog’s overall happiness and strengthen the bond you share.
Diversify Playtime
Traditional fetch is a classic game, but expanding your play sessions to include interactive toys, agility courses, and the teaching of new tricks can significantly stimulate your dog’s mind and body. These activities are not just fun; they challenge your dog, keeping them mentally sharp and physically fit. An engaged dog is a happy dog, and by incorporating variety into your playtime, you ensure their days are filled with anticipation and excitement.
Upgrade Their Living Space
A nurturing environment for your dog goes beyond daily walks and playtime; it extends into the realm of maintaining a safe and secure home. Leveraging a home maintenance and repair app can be a game-changer for pet owners, offering an efficient way of covering repair and maintenance. These digital tools simplify the process of arranging service appointments. Furthermore, they connect homeowners with skilled professionals, ready to provide estimates for any necessary work, keeping the living space both comfortable and safe for your furry friend.
Plan for Daily Exercise
Tailoring daily exercise to match your dog’s breed and energy level is crucial for their overall well-being. Incorporating at least 30 minutes of brisk walking or running into their routine plays a pivotal role in maintaining physical fitness and mental alertness. This practice acts as a fundamental pillar of health, warding off boredom and potential behavioral problems, thereby securing a state of contentment and optimal health for your pet. Moreover, this commitment to regular physical activity reinforces your bond with your dog, highlighting the shared experiences that enrich your relationship.
Socialize Regularly
Socialization introduces your dog to new experiences and fellow canines, crucial for their emotional development. Visits to dog parks, pet-friendly stores, or arranging doggy playdates offer your dog a chance to develop social skills and enjoy a variety of experiences. Such outings enrich your dog’s life, offering new sights, sounds, and smells to explore, keeping their days interesting and fulfilling.
Consistent Training Sessions
Consistent training sessions are crucial for both teaching your dog new skills and enhancing the bond between you and your pet. By employing positive reinforcement methods, you not only make learning enjoyable for your dog but also significantly strengthen your relationship. Keeping the training sessions regular and brief ensures your dog’s mental stimulation is high and reaffirms their status as a cherished family member. The technique of positive reinforcement turns each training encounter into an anticipated and joyous occasion, underscoring the pleasure found in the learning process.
Mealtime Enrichment
Transforming mealtime into a game satisfies your dog’s natural foraging instincts. Puzzle feeders, snuffle mats, or hiding treats around the house can turn a routine meal into an exciting adventure. This not only enriches their daily routine but also provides mental stimulation, keeping their minds sharp and engaged.
Provide a Cozy Retreat
Ensuring your dog has a comfortable resting area is essential for their sense of security and well-being. Spending time each day on calm interactions, such as petting or grooming, reinforces their feeling of love and security. A dedicated space for rest and the assurance of your love helps them feel safe and cherished, fostering a deep sense of well-being.
Adopting these strategies not only improves your dog’s physical and mental health but also enhances the bond you share, making each moment together richer and more meaningful. Each practice, from diversifying playtime to ensuring a comfortable living space, plays a vital role in your dog’s overall happiness. By investing time and love into your dog’s well-being, you ensure they lead a fulfilling life, full of joy and love. Embrace these strategies and witness the transformation in your dog’s life, knowing you’re providing the best care and affection possible.
