So if we are discussing feelings, as we are today, there is no better place to start than by me expressing my feelings of joy and love that I feel for, and still receive from, my gorgeous Jean. I know five years at our stage of life is far fewer than for many married couples but, nevertheless, they have been beautiful years and I wish for many more.

I had been pondering these last few days as to what I would write for today. For I wanted to celebrate our anniversary yet wanted a broader theme; so to speak.
There couldn’t have been a better answer to that ponder than a recent video that was presented by TED Talks. It was a talk by Carl Safina about what is going on inside the brains of animals: What are animals thinking and feeling? Or in the fuller words of that TED Talk page:
What’s going on inside the brains of animals? Can we know what, or if, they’re thinking and feeling? Carl Safina thinks we can. Using discoveries and anecdotes that span ecology, biology and behavioral science, he weaves together stories of whales, wolves, elephants and albatrosses to argue that just as we think, feel, use tools and express emotions, so too do the other creatures – and minds – that share the Earth with us.
Safina is very qualified to speak on the subject as his bio on that TED Talk page reveals. However, I couldn’t find a YouTube link for that TED Talk but could find two videos that are very good alternatives.
The first is a short video of Safina promoting his book Beyond Words: What Animals Think and Feel.
The second is a much longer video that is Safina’s presentation at the recent Ransom A. Myers Lecture. If you can spare the time, then do watch it. You will not be disappointed.

Last but not least! A photograph taken two days ago by yours truly reflecting my feelings of wonder at being alive in this world!
A video on YouTube raises some fundamental questions about our changing climate.
Let me say straight away that my belief in Anthropogenic Global Warming (AGW) is based on instinct, and not on me understanding the science, simply because I am not a scientist; far from it! As I share on this blog:
Paul Handover is a child of the post-war era in Great Britain having been born in London a few months before the end of WWII. After a rather shaky attempt at being educated, including 2 years studying for a Diploma in Electrical Engineering, Paul’s first job was as a commercial apprentice at the British Aircraft Corporation. He then joined the sales desk of British Visqueen, a polythene film and products manufacturer located in Stevenage, Hertfordshire, and part of ICI Plastics Division. In 1968, he travelled out to Sydney, Australia and became part of the sales team at ICIANZ’s Inorganic Chemicals Division.
I am a fundamentally a retired salesman/entrepreneur with a very out-of-date knowledge of electrical engineering and radio communications (G3PUK), and now struggling to be an author. 😉
Plus, my generally sceptical view of how countries are governed, my awareness of a terrible lack of integrity in politicians, plays to those instincts of mine that humanity is, indeed, responsible primarily for our changing climate. And there is no shortage of supporting evidence!
A very quick web search found this NASA site that included the following graph and text (in part):
This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution. (Credit: Vostok ice core data/J.R. Petit et al.; NOAA Mauna Loa CO2 record.)
The Earth’s climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era — and of human civilization. Most of these climate changes are attributed to very small variations in Earth’s orbit that change the amount of solar energy our planet receives.
Scientific Consensus
Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities, and most of the leading scientific organizations worldwide have issued public statements endorsing this position.
Click here for a partial list of these public statements and related resources.
However, a dear and close friend of nearly 40 years, Dan Gomez, is sceptical and simply says to me: “Paul, follow the money!” Dan is a very widely-read person and a great thinker.
Plus, among our wonderful neighbours there is a couple, Dordie and Bill, that we get on with extremely well. Bill is a sceptic of AGW and recently sent me the link to the following video.
Please watch it. If you have evidence that all or many of the facts on this video are incorrect then I would love to hear from you.
For this is way too important for the truth not to be widely promoted.
With seventeen pets here at home Jean and I should live forever!
Another Saturday and another gentle post about the power of our wonderful pets. (Oh, and who, as I did, missed the fact that yesterday was not only a Friday the Thirteenth but the third one this year!)
Anyway, back to the plot!
Last Monday, Mother Nature Network published an item about how good pets are for our health. It seemed the perfect item to share with all of you this Saturday.

11 studies that prove pets are good for your health
Check out the ways your 4-legged friends enhance your physical and emotional health.
By: Sidney Stevens, November 9, 2015.
Pets strengthen our hearts, calm our nerves and a whole lot more. (Photo: Juanedc.com /flickr)
If you have pets you already know the joy and love they bring to your life. Now science is confirming just how good they really are for you — both mentally and physically.
How do they help? One theory is that pets boost our oxytocin levels. Also known as the “bonding hormone” or “cuddle chemical,” oxytocin enhances social skills, decreases blood pressure and heart rate, boosts immune function and raises tolerance for pain. It also lowers stress, anger and depression.
No surprise then that keeping regular company with a dog or cat (or another beloved beast) appears to offer all these same benefits and more. Read on to discover the many impressive ways a pet can make you healthier, happier and more resilient.
1. Pets alleviate allergies and boost immune function
One of your immune system’s jobs is to identify potentially harmful substances and unleash antibodies to ward off the threat. But sometimes it overreacts and misidentifies harmless stuff as dangerous, causing an allergic reaction. Think red eyes, itchy skin, runny nose and wheezing. You’d think that having pets might trigger allergies by kicking up sneeze-and-wheeze-inducing dander and fur. But it turns out that living with a dog or cat during the first year of life not only cuts your chances of having pet allergies in childhood and later on but also revs up your immune system and lowers your risk of eczema and asthma. In fact, just a brief pet encounter can invigorate your disease-defense system. In one study, petting a dog for only 18 minutes raised immunoglobulin A (IgA) levels in college students’ saliva, a sign of robust immune function.
2. Pets up your fitness quotient
This one applies more to dog owners. If you like walking with your favorite canine, chances are you’re fitter and trimmer than your non-dog-walking counterparts and come closer to meeting recommended physical activity levels. One study of more than 2,000 adults found that regular dog walkers got more exercise and were less likely to be obese than those who didn’t walk a dog. In another study, older dog walkers (ages 71-82) walked faster and longer than non-pooch-walkers, plus they were more mobile at home.

3. Pets dial down stress
When stress comes your way, your body goes into fight-or-flight mode, releasing hormones like cortisol to crank out more energy-boosting blood sugar and epinephrine to get your heart and blood pumping. All well and good for our ancestors who needed quick bursts of speed to dodge predatory saber-toothed tigers and stampeding mastodons. But when we live in a constant state of fight-or-flight from ongoing stress at work and the frenetic pace of modern life, these physical changes take their toll on our bodies, including raising our risk of heart disease and other dangerous conditions. Contact with pets seem to counteract this stress response by lowering stress hormones and heart rate. They also lower anxiety and fear levels (psychological responses to stress) and elevate feelings of calmness.
4. Pets boost heart health
Pets shower us with love so it’s not surprising they have a big impact on our love organ: the heart. Turns out time spent with a cherished critter is linked to better cardiovascular health, possibly due to the stress-busting effect mentioned above. Studies show that dog owners have a lower risk of heart disease, including lower blood pressure and cholesterol. Dogs also benefit patients who already have cardiovascular disease. They’re not only four time more likely to be alive after a year if they own a dog, but they’re also more likely to survive a heart attack. And don’t worry, cat owners — feline affection confers a similar effect. One 10-year study found that current and former cat owners were 40 percent less likely to suffer a heart attack and 30 percent less likely to die of other cardiovascular diseases.
5. Make you a social — and date — magnet
Four-legged companions (particularly the canine variety that pull us out of the house for daily walks) help us make more friends and appear more approachable, trustworthy and date-worthy. In one study, people in wheelchairs who had a dog received more smiles and had more conversations with passersby than those without a dog. In another study, college students who were asked to watch videos of two psychotherapists (depicted once with a dog and once without) said they felt more positively toward them when they had a dog and more likely to disclose personal information. And good news for guys: research shows that women are more willing to give out their number to men with a canine buddy.

6. Provides a social salve for Alzheimer’s patients
Just as non-human pals strengthen our social skills and connection, cats and dogs also offer furry, friendly comfort and social bonding to people suffering from Alzheimer’s and other forms of brain-destroying dementia. Several canine caregiver programs now exist to assist at-home dementia patients with day-to-day tasks, such as fetching medication, reminding them to eat and guiding them home if they’ve wandered off course. Many assisted-living facilities also keep resident pets or offer therapy animal visits to support and stimulate patients. Studies show creature companions can reduce behavioral issues among dementia patients by boosting their moods and raising their nutritional intake.
7. Enhances social skills in kids with autism
One in nearly 70 American kids has autism (also known as autism spectrum disorder, or ASD), a developmental disability that makes it tough to communicate and interact socially. Not surprisingly, animals can also help these kids connect better to others. One study found that youngsters with ASD talked and laughed more, whined and cried less and were more social with peers when guinea pigs were present. A multitude of ASD animal-assisted therapy programs have sprung up in recent years, featuring everything from dogs and dolphins to alpacas, horses and even chickens.

8. Dampens depression and boosts mood
Pets keep loneliness and isolation at bay and make us smile. In other words, their creature camaraderie and ability to keep us engaged in daily life (via endearing demands for food, attention and walks) are good recipes for warding off the blues. Research is ongoing, but animal-assisted therapy is proving particularly potent in deterring depression and other mood disorders. Studies show that everyone from older men in a veterans hospital who were exposed to an aviary filled with songbirds to depressed college students who spent time with dogs reported feeling more positive.
9. Defeats PTSD
People haunted by trauma like combat, assault and natural disasters are particularly vulnerable to a mental health condition called post-traumatic stress disorder (PTSD). Sure enough, studies show that the unconditional love — and oxytocin boost — of a pet can help remedy the flashbacks, emotional numbness and angry outbursts linked to PTSD. Even better, there are now several programs that pair specially trained service dogs and cats with veterans suffering from PTSD.
10. Fights cancer
Animal-assisted therapy helps cancer patients heal emotionally and physically. Preliminary findings of an on-going clinical trial by the American Humane Association shows that therapy dogs not only erase loneliness, depression and stress in kids fighting cancer, but canines can also motivate them to eat and follow treatment recommendations better — in other words participate more actively in their own healing. Likewise, new research reveals a similar lift in emotional well-being for adults undergoing the physical rigors of cancer treatment. Even more astounding, dogs (with their stellar smelling skills) are now being trained to literally sniff out cancer.
11. Puts the kibosh on pain
Millions live with chronic pain, but animals can soothe some of it away. In one study, 34 percent of patients with the pain disorder fibromyalgia reported pain relief (and a better mood and less fatigue) after visiting for 10-15 minutes with a therapy dog compared to only 4 percent of patients who just sat in a waiting room. In another study, those who had undergone total joint replacement surgery needed 28 percent less pain medication after daily visits from a therapy dog than those who got no canine contact.

When I was setting this post up and copying across all the many links I was aware that there was a mountain of information out there. You may want to take some time and explore those links. For example, the link to HABRI- Human-Animal Research Initiative looks incredibly interesting. Then there was the link to the work being undertaken by the American Humane Association, that link being to this video that I am presenting here to close off today’s post.
Wherever you are in the world look after yourself and care for all those lovely pets out there. Love them so dearly!
What is happening in beautiful Indonesia is beyond imagination.
I am indebted to John Zande for introducing me to the word kakistocracy, that he explained means: “government by the worst persons; a form of government in which the worst persons are in power.”
For what is happening in Indonesia could well be an awful example of kakistocracy in action.
Like numerous others I knew that there were fires burning in Indonesia and that it was all somehow caught up in illegal logging, but knew little over and above that. And that is the crux of the title of a recent essay from George Monbiot: Nothing to See Here. It really is a “must read” essay and is republished below with Mr. Monbiot’s very kind permission. As with most of his essays, they are published in the Guardian newspaper. In this case, the Guardian version includes photographs that vividly underline the terrible situation out there. I agonised about copying them from the Guardian article, without explicit permission to so do, but have nevertheless done so on the basis of this story needing to make the maximum impact on readers. The photographs are inserted in Monbiot’s essay very closely to the format that is presented in the Guardian article.

Nothing to See Here
30th October 2015

In the greatest environmental disaster of the 21st Century (so far), Indonesia has been blotted out by smoke. And the media.
By George Monbiot, published in the Guardian 30th October 2015.
I’ve often wondered how the media would respond when eco-apocalypse struck. I pictured the news programmes producing brief, sensational reports, while failing to explain why it was happening or how it might be stopped. Then they would ask their financial correspondents how the disaster affected share prices, before turning to the sport. As you can probably tell, I don’t have an ocean of faith in the industry for which I work.
What I did not expect was that they would ignore it.
A great tract of the Earth is on fire. It looks as you might imagine hell to be. The air has turned ochre: visibility in some cities has been reduced to 30 metres. Children are being prepared for evacuation in warships; already some have choked to death. Species are going up in smoke at an untold rate. It is almost certainly the greatest environmental disaster of the 21st Century – so far.
[NB: The video that is embedded in the Guardian version is without sound. I have added one that is also a Greenpeace video, with sound, further on in the post.]
And the media? It’s talking about the dress the Duchess of Cambridge wore to the James Bond premiere, Donald Trump’s idiocy du jour and who got eliminated from the Halloween episode of Dancing with the Stars. The great debate of the week, dominating the news across much of the world? Sausages: are they really so bad for your health?
What I’m discussing is a barbeque on a different scale. Fire is raging across the 5000-kilometre length of Indonesia. It is surely, on any objective assessment, more important than anything else taking place today. And it shouldn’t require a columnist, writing in the middle of a newspaper, to say so. It should be on everyone’s front page.
It is hard to convey the scale of this inferno, but here’s a comparison that might help: it is currently producing more carbon dioxide than the US economy. In three weeks the fires have released more CO2 than the annual emissions of Germany.

But that doesn’t really capture it. This catastrophe cannot be measured only in parts per million. The fires are destroying treasures as precious and irreplaceable as the archaeological remains being levelled by Isis. Orang utans, clouded leopards, sun bears, gibbons, the Sumatran rhinoceros and Sumatran tiger, these are among the threatened species being driven from much of their range by the flames. But there are thousands, perhaps millions, more.
One of the burning islands is West Papua, a nation that has been illegally occupied by Indonesia since 1963. I spent six months there when I was 24, investigating some of the factors that have led to the current disaster. At the time, it was a wonderland, rich with endemic species in every swamp and valley. Who knows how many of those have vanished in the past few weeks? This week I have pored and wept over photos of places I loved, that have now been reduced to ash.
Nor do the greenhouse gas emissions capture the impact on the people of these lands. After the last great conflagration, in 1997, there was a missing cohort in Indonesia of 15,000 children under the age of three, attributed to air pollution. This, it seems, is worse. The surgical masks being distributed across the nation will do almost nothing to protect those living in a sunless smog. Members of parliament in Kalimantan (Indonesian Borneo) have had to wear face masks during debates. The chamber is so foggy that they must have difficulty recognising each other.
It’s not just the trees that are burning. It is the land itself. Much of the forest sits on great domes of peat. When the fires penetrate the earth, they smoulder for weeks, sometimes months, releasing clouds of methane, carbon monoxide, ozone and exotic gases like ammonium cyanide. The plumes extend for hundreds of miles, causing diplomatic conflicts with neighbouring countries.
Why is this happening? Indonesia’s forests have been fragmented for decades by timber and farming companies. Canals have been cut through the peat to drain and dry it. Plantation companies move in to destroy what remains of the forest to plant monocultures of pulpwood, timber and palm oil. The easiest way to clear the land is to torch it. Every year, this causes disasters. But in an extreme El Niño year like this one, we have a perfect formula for environmental catastrophe.
The current president, Joko Widodo, is – or wants to be – a democrat. But he presides over a nation in which fascism and corruption flourish. As Joshua Oppenheimer’s documentary The Act of Killing shows, leaders of the death squads that helped murder around a million people during Suharto’s terror in the 1960s, with the approval of the West, have since prospered through other forms of organised crime, including illegal deforestation.
They are supported by a paramilitary organisation with three million members, called Pancasila Youth. With its orange camo-print uniforms, scarlet berets, sentimental gatherings and schmaltzy music, it looks like a fascist militia as imagined by JG Ballard. There has been no truth, no reconciliation; the mass killers are still greeted as heroes and feted on television. In some places, especially West Papua, the political murders continue.
Those who commit crimes against humanity don’t hesitate to commit crimes against nature. Though Joko Widodo seems to want to stop the burning, his reach is limited. His government’s policies are contradictory: among them are new subsidies for palm oil production that make further burning almost inevitable. Some plantation companies, prompted by their customers, have promised to stop destroying the rainforest. Government officials have responded angrily, arguing that such restraint impedes the country’s development. That smoke blotting out the nation, which has already cost it some $30 billion? That, apparently, is development.
Our leverage is weak, but there are some things we can do. Some companies using palm oil have made visible efforts to reform their supply chains; but others seem to move slowly and opaquely. Starbucks, PepsiCo, Kraft Heinz and Unilever are examples. Don’t buy their products until they change.
On Monday, Widodo was in Washington, meeting Barack Obama. Obama, the official communiqué recorded, “welcomed President Widodo’s recent policy actions to combat and prevent forest fires”. The ecopalypse taking place as they conferred, that makes a mockery of these commitments, wasn’t mentioned.
Governments ignore issues when the media ignores them. And the media ignores them because … well there’s a question with a thousand answers, many of which involve power. But one reason is the complete failure of perspective in a deskilled industry dominated by corporate press releases, photo ops and fashion shoots, where everyone seems to be waiting for everyone else to take a lead. The media makes a collective non-decision to treat this catastrophe as a non-issue, and we all carry on as if it’s not happening.
At the climate summit in Paris in December, the media, trapped within the intergovernmental bubble of abstract diplomacy and manufactured drama, will cover the negotiations almost without reference to what is happening elsewhere. The talks will be removed to a realm with which we have no moral contact. And, when the circus moves on, the silence will resume. Is there any other industry that serves its customers so badly?
A quick web search will offer endless pictures of this great tragedy but I will leave you with three; two showing the extent of the smoke and one that is much more an intimate photograph of the suffering animals.

In this Thursday, March 1, 2012, Indonesian veterinarian Yenni Saraswati, top center, of Sumatran Orangutan Conservation Programme (SOCP) examines the condition of an injured Sumatran orangutan found by environmental activists at a palm oil plantation in Rimba Sawang village, Aceh province, Indonesia. Conservationists say fires in an Indonesian swamp forest may have killed a third of the rare Sumatran orangutans living there and all of them may be lost this year. Binsar Bakkara, Associated Press.
Monbiot wrote: “Those who commit crimes against humanity don’t hesitate to commit crimes against nature.”
One cannot avoid reflecting that this would not have happened if there hadn’t been, “government by the worst persons; a form of government in which the worst persons are in power.”
Procrastination is the art of keeping up with yesterday.
Can’t claim credit for the sub-heading; it was taken from BrainyQuote.
However, the reason I went looking for a quotation on procrastinating was that I’m doing research for a fairly “heavy” post for tomorrow, and was looking for something quick and easy for today.
My blog folder came up with an essay from The Conversation website that is rather fun. It is republished here on Learning from Dogs within the terms of The Conversation.

The psychological origins of procrastination – and how we can stop putting things off
October 7, 2015
Authors: Elliot Berkman, Assistant Professor, Psychology, University of Oregon, and Jordan Miller-Ziegler, PhD Candidate in Psychology, University of Oregon.
“I love deadlines,” English author Douglas Adams once wrote. “I love the whooshing noise they make as they go by.”
We’ve all had the experience of wanting to get a project done but putting it off for later. Sometimes we wait because we just don’t care enough about the project, but other times we care a lot – and still end up doing something else. I, for one, end up cleaning my house when I have a lot of papers to grade, even though I know I need to grade them.
So why do we procrastinate? Are we built to operate this way at some times? Or is there something wrong with the way we’re approaching work?
These questions are central to my research on goal pursuit, which could offer some clues from neuroscience about why we procrastinate – and how to overcome this tendency.
To do, or not to do
It all starts with a simple choice between working now on a given project and doing anything else: working on a different project, doing something fun or doing nothing at all.
The decision to work on something is driven by how much we value accomplishing the project in that moment – what psychologists call its subjective value. And procrastination, in psychological terms, is what happens when the value of doing something else outweighs the value of working now.
This way of thinking suggests a simple trick to defeat procrastination: find a way to boost the subjective value of working now, relative to the value of other things. You could increase the value of the project, decrease the value of the distraction, or some combination of the two.
For example, instead of cleaning my house, I might try to focus on why grading is personally important to me. Or I could think about how unpleasant cleaning can actually be – especially when sharing a house with a toddler.
It’s simple advice, but adhering to this strategy can be quite difficult, mainly because there are so many forces that diminish the value of working in the present.
The distant deadline
People are not entirely rational in the way they value things. For example, a dollar bill is worth exactly the same today as it is a week from now, but its subjective value – roughly how good it would feel to own a dollar – depends on other factors besides its face value, such as when we receive it.
The tendency for people to devalue money and other goods based on time is called delay discounting. For example, one study showed that, on average, receiving $100 three months from now is worth the same to people as receiving $83 right now. People would rather lose $17 than wait a few months to get a larger reward.
Other factors also influence subjective value, such as how much money someone has recently gained or lost. The key point is that there is not a perfect match between objective value and subjective value.
Delay discounting is a factor in procrastination because the completion of the project happens in the future. Getting something done is a delayed reward, so its value in the present is reduced: the further away the deadline is, the less attractive it seems to work on the project right now.
Studies have repeatedly shown that the tendency to procrastinate closely follows economic models of delay discounting. Furthermore, people who characterize themselves as procrastinators show an exaggerated effect. They discount the value of getting something done ahead of time even more than other people.
Not only can completing a project be devalued because it happens in the future, but working on a project can also be unattractive due to the simple fact that work takes effort.
This leads to the interesting prediction that people would procrastinate more the harder they expect the work to be. That’s because the more effort a task requires, the more someone stands to gain by putting the same amount of effort into something else (a phenomenon economists call opportunity costs). Opportunity costs make working on something that seems hard feels like a loss.
Sure enough, a group of studies shows that people procrastinate more on unpleasant tasks. These results suggest that reducing the pain of working on a project, for example by breaking it down into more familiar and manageable pieces, would be an effective way to reduce procrastination.
Your work, your identity
When we write that procrastination is a side effect of the way we value things, it frames task completion as a product of motivation, rather than ability.
In other words, you can be really good at something, whether it’s cooking a gourmet meal or writing a story, but if you don’t possess the motivation, or sense of importance, to complete the task, it’ll likely be put off.
It was for this reason that the writer Robert Hanks, in a recent essay for the London Review of Books, described procrastination as “a failure of appetites.”
The source of this “appetite” can be a bit tricky. But one could argue that, like our (real) appetite for food, it’s something that’s closely intertwined with our daily lives, our culture and our sense of who we are.
So how does one increase the subjective value of a project? A powerful way – one that my graduate students and I have written about in detail – is to connect the project to your self-concept. Our hypothesis is that projects seen as important to a person’s self-concept will hold more subjective value for that person.
It’s for this reason that Hanks also wrote that procrastination seems to stem from a failure to “identify sufficiently with your future self” – in other words, the self for whom the goal is most relevant.
Because people are motivated to maintain a positive self-concept, goals connected closely to one’s sense of self or identity take on much more value.
Connecting the project to more immediate sources of value, such as life goals or core values, can fill the deficit in subjective value that underlies procrastination.
ooOOoo
So there; glad that’s clear for us all.
Mustn’t delay – I need to write down a list of all the things I’m not doing today!
Asteroid 2015 TB145 will pass by Planet Earth – just!
Back in my old country, Halloween is not celebrated in the same style that it is here in America. The Brits tend to favour the evening of November 5th and Guy Fawkes Night. That evening, Bonfire Night, sees fireworks parties in many places.
However, if one starts to think of the dimensions and distances of outer space then our planet is just being spared the firework show to beat all other shows.
I’m referring to Asteroid TB145, a huge asteroid, that will pass Earth at 310,000 miles (498,896 km) or 1.3 times the Earth-moon distance.
UPDATE OCTOBER 30, 2015. A newly found asteroid of notable size – known as asteroid 2015 TB145 – will safely pass Earth on October 31, 2015, according to clocks in North America. It should be visible moving in front of the stars, with the help of a telescope, tonight (October 30). It is the biggest known asteroid that will come this close to Earth until 2027. The asteroid – found as recently as October 10 – will fly past Earth at a safe distance, or about 1.3 times the moon’s distance. Closest approach to Earth will be October 31 at 1 p.m. EDT (1700 UTC). Translate to your time zone here.
Paul Chodas, manager of the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory, Pasadena, California, said:
The trajectory of 2015 TB145 is well understood. At the point of closest approach, it will be no closer than about 300,000 miles – 480,000 kilometers or 1.3 lunar distances. Even though that is relatively close by celestial standards, it is expected to be fairly faint, so night-sky Earth observers would need at least a small telescope to view it.
So how big is this asteroid?
Scientists are continuing to estimate the size at 1,300 feet (400 meters) wide.
If the size is correct, the new found asteroid is 28 times bigger in diameter than the Chelyabinsk meteor that penetrated the atmosphere over Russia in February, 2013. An incoming asteroid’s potential to do damage on Earth depends on various factors, including its size, its angle of entry, and the point on Earth over which it enters the atmosphere. The shock wave from the 2013 Chelyabinsk meteor broke windows and did other damage to some 7,200 buildings in six Russian cities. Some 1,500 people were injured seriously enough to seek medical treatment, mainly from broken glass from windows.
For those of you that want to catch a glimpse of TB145, then:
Asteroid position at 3:50 a.m. ET (0750 UTC) Point a Go To computerized telescope to HIP 24197 or SAO 94377) a naked-eye star with a magnitude of 5 in Orion. At 3:50 a.m. ET on October 31 (Saturday morning), the space rock passes close to this star. The asteroid will appear as a slowly moving ‘star’ passing very close to this star. By this time the asteroid should appear to move faster because it will be closer to Earth than earlier on the night of October 30. This illustration shows a half degree field of view (about the size of a full moon). A pair of double stars visible in this area should confirm you are pointing at the correct direction. Alternatively, you can point your telescope to these coordinates: RA 05h 11m 41.6s / DEC +16º 02′ 44.5″. Illustration by Eddie Irizarry using Stellarium.
Full details and answers to most of your questions may be found here.
All I can say is I hope the number crunchers have got their sums right!
If not, then it’s goodnight from her and goodnight from me.
It was nice knowing you all!
P.S. If you think this is all a bit far-fetched, then this video sent to me by Dan Gomez will bring you down to earth.
I feel a little guilty at just dropping this full article in your path, and running away, so to speak, but yesterday was one of those days where Jean and I were “full on” for most of the day, and then out from the house from 4pm onwards.
It doesn’t lessen the interest, in my humble opinion, of this essay, that was recently published by The Conversation, and is republished within their terms.

New DNA analysis says your pooch’s ancestors were Central Asian wolves
October 20, 2015
Author: Laura Shannon, Postdoctoral Research Associate in Biological Sciences, Cornell University
Dogs’ origin story goes something like this: sometime between 16,000 and 30,000 years ago, there were some stressed-out hungry wolves whose hunting territory had been encroached upon by humans. Luckily, these wolves were resourceful and they noticed human beings have a tendency to leave delicious things lying around. Scavenging leftovers seemed significantly easier than going out and hunting, so they hung around the people.
Wolves make unnerving neighbors. However, some are less unnerving than others. The humans were a lot more inclined to tolerate the proximity of less aggressive, more people-oriented wolves. As an added bonus, other predators are less likely to harass you when you are surrounded by wolves. So the people and the nicest wolves came to an agreement – the people tolerated and fed the tamest and most helpful wolves.
Smart, tame wolves have smarter, tamer wolf cubs, and so over time the wolves became more and more pleasant to have around. Obviously, friendly, helpful wolves hanging around people and eating leftovers aren’t really wolves; we have a word for those things – they’re dogs.
That’s biologists’ reasonable guess for how dogs came about. We have some idea when it all happened, but it’s been harder to figure out where. Who first took in scavenging gray wolves and turned them into dogs?
Dogs still know a good thing when they see it – warmth and food with people ‘round the campfire. Camping image via http://www.shutterstock.com.
However, the oldest dog bones anyone has found are from the other end of Eurasia, all the way in Northern Europe. Furthermore, the mitochondria of modern dogs are closely related to the mitochondria of ancient European wolves.
Finally, Middle Eastern wolves share the most genetic sequences with today’s dogs, which makes it seem like maybe Middle Eastern wolves are the ancestral wolf population.
All these threads of evidence broadly agree that dogs are from somewhere in Eurasia. But my colleagues and I wanted to narrow that down a bit – and to do that, we decided we needed DNA from as many dogs as possible for our new study.

Modern dogs cover the globe
Dogs are found almost everywhere people are, and over time we have bred them to do everything from guarding livestock to going fishing. The breeds we’ve created come in many shapes and sizes, ranging from tiny Chihuahuas to giant Great Danes. The vast majority of these breeds are less than 200 years old and come from Europe. But these purebred dogs or even mixes of these breed dogs are the minority of dogs on the planet.
Most dogs are free-ranging village dogs, which live around and among people but aren’t necessarily what you’d think of as pets. You can learn more about ancient dogs by studying these village dogs (as compared to studying breed dogs) because village dogs have more genetic diversity; the number of different versions of the same genes in village dogs is higher than it is in breed dogs.
All dogs were formed from a select group of wolves, and therefore have a subset of the genetic diversity found in wolves. But breeds were formed from a subset of dogs so they have only a further subset of the diversity found in dogs.

Tracing the trail through DNA sequences
Members of our lab traveled to collect blood or spit from dogs in a variety of locales, and collaborators sent us fluids from places to which we didn’t manage to travel. Village dogs are fairly easy to find for researchers carrying food. In total, we extracted DNA from the fluids of 549 dogs from 38 countries spanning the majority of the globe as well as 4,676 purebred dogs. Our lab at Cornell is conveniently located in the same building as a veterinary hospital, so most of our purebred dogs were patients.
Once we had our samples, we then determined each dog’s genotype at about 180,000 distinct points in the genome. This is the largest data set anyone has used to address the question of dog origins so far.
We were looking for a very specific pattern of historical genetic diversity. When a select group of wolves became dogs, those dogs contained only the genetic diversity present in that subset of wolves. When people took some of the dogs and moved on to new regions of the globe, or traded dogs with people in other regions, they took only a subset of the total dogs, and by extension a subset of the total diversity.
Therefore, we expect the original population of dogs to be the most diverse. There would be a gradient of decreasing diversity in all populations as they move away from the center of origin.
And this is the pattern we observed when we compared the genetics of dogs from different populations. Dogs from Central Asia, Mongolia and Nepal are the most diverse, with genomes that correspond to the early, original variation in the population right after domestication happened. When we look at the same DNA markers in dogs from neighboring regions, diversity decreases. It decreases further corresponding to the location’s increasing distance from Central Asia. This is the pattern we would expect if the people who first took in scavenging gray wolves and turned them into dogs were located in Central Asia.

Looking at the largest data set of dogs amassed so far, we observe a very clear signal that most dogs alive today descended from dogs in Central Asia. However, we only looked at dogs alive right now. We have no information about historical populations of dogs that have no living descendants. Furthermore, the patterns of diversity we observe are reflective of the origins of dogs but also of everything that has happened to dog populations since domestication.
Other research groups are extracting DNA from bones of ancient dogs, and these sequences will provide exciting new insights from time points closer to domestication. However, ancient DNA studies are limited by the availability of ancient dog bones – which is affected by many factors other than the distribution of historic populations; for instance, some environments are more conducive to the preservation of bone and DNA than others, some regions have been more extensively investigated by archaeologists than others, and so on. If we see similar patterns in ancient and modern dogs, that will add clarity to the history of dogs and the people who love them.

Ultimately, it doesn’t matter one hoot, in a non-scientific sense, from where our dogs are descended. Just that they did evolve.
For human life without our dogs would be unthinkable.
The vastness of the seas and the immensity of their influence over all of us.
This is an introduction, a rather long one I’m warning, to a republication of a recent post by Patrice Ayme. An introduction that offers a deeply personal memory of the Atlantic ocean.
Many years ago, I spent 5 years living on a boat; a wonderful heavy-displacement ocean-going yacht of a type known as a Tradewind 33.
My home for five years – Tradewind 33: Songbird of Kent.
There is a place in my mind to which I can so easily travel; a memory of a dark night out in the Atlantic ocean one time in the Autumn of 1969. But first let me set the scene from almost fifty years ago.
The call of the open ocean
Those first few hours were utterly absorbing as I went through the whole business of clearing the yacht harbour at Gibraltar and heading out to the South-West hugging this unfamiliar coastline of Southern Spain. It was tempting to move out to deeper waters but the almost constant flow of large ships through the Straights of Gibraltar soon quashed that idea. Thankfully, the coastal winds were favourable for me and my single-masted sailing yacht.
After such a long time sailing in the relatively confined waters of the Mediterranean, it was difficult for me to imagine that in a few hours time the southern-most point of Spain would pass me by and the vastness of the Atlantic ocean would be my home for the next few weeks.
Soon the city of Tarifa was past my starboard beam and the Spanish coastline was rapidly disappearing away to the North-West. The horizon ahead of me was already approaching 180 degrees of raw, open ocean. There was just a flicker of a thought that whispered across my mind: “Oh Paul, what have you gone and done” as slowly but persistently the coastlines of Spain to the North and of Africa to the South became more and more distant and fuzzy. It was at 15:30 that I made an entry in my yacht’s log: “No land in sight in any direction!”
Now was the time to make sure that my bunk was made up, flashlights to hand, and my alarm clock ready and set. Alarm clock? Set to go off every twenty minutes during the night! For this was the only way to protect me and my yacht from being hit by one of those gigantic container ships that seemed to be everywhere. It took at least twenty minutes from the moment a ship’s steaming lights appeared above the horizon to crossing one’s path!
It was in the early hours of my first morning alone at sea, when once again the alarm clock had woken me and I was looking around an ocean without a single ship’s light to be seen that more of Les’ words (see footnote) came to me. I remembered asking Les: “What’s the appeal of sailing?” Les replied without a moment’s hesitation: “It’s the solitude. When you’re out at sea on your own, there’s no government or bankers to worry about. You’re not responsible to anyone but yourself.”
Yes, I could sense the solitude that was all around me but it was an intellectual sense not an emotional one. That would come later. Inside, I was still afraid of what I had let myself in for.
Remarkably quickly however, the pattern of solo life aboard a thirty-three-foot yacht became my world. Frankly, it staggered me as to how busy were my days. Feeding myself, navigating, trying to forecast the winds, staying in touch with other yachties via the short-wave radio, keeping the boat tidy and a zillion other tasks meant the first few days and nights just slipped by.
But it was a sight on my fourth night at sea that created the memory that would turn out to remain with me for all my life. The memory that I can go to anytime in my mind.
That fourth night I was already well into the routine of waking to the alarm clock, clipping on my harness as I climbed up the three steps that took me from my cabin into the cockpit, scanning the horizon with my eyes, checking that the self-steering had the boat at the correct angle to the wind and then, if no ships’ lights had been seen, slipping back down into my bunk and sleeping for another twenty minutes. Remarkably, I was not suffering from any long-term tiredness during the day.
It was a little after 3am that fourth night when the alarm clock had me back up in the cockpit once again. Then it struck me.
Songbird was sailing beautifully. There was a steady wind of around ten knots from the south-east, almost a swell-free ocean, and everything set perfectly. Not a sign of any ship in any direction.
Then I lifted my eyes upwards. There was not a cloud in the night sky, not a single wisp of mist to dim a single one of the million or more stars that were above my head. For on this dark, moonless night, so far removed from any shore-based light pollution, the vastness, yet closeness of the heavens above was simply breath-taking. I was transfixed. Utterly unable to make any rational sense of this night splendour that glittered in every direction in which I gazed. This dome that represented a vastness beyond any meaning other than a reminder of the magic of the universe.
This magic of the heavens above me that came down to touch the horizon in all directions. Such a rare sight to see the twinkling of stars almost touching the starkness of the ocean’s horizon at night. A total marriage of this one planet with the vastness of outer space.
I heard the alarm clock go off again and again next to my bunk down below. But I remained transfixed until there was a very soft lightening of the skyline to the east that announced that another dawn was on its way.
I would never again look up at the stars in a night sky without being transported back to that wonderful night and the memory of a lonely sea and sky.
I did warn you it would be a long introduction!

Non-Linear Cold Blob Rising Over North Atlantic
The reason life survived on Earth for so long, and blossomed into animals, and now mind, is that the planet is equipped with homeostatic mechanisms (homeo means similar in Greek, and stasis, standing still). However, those mechanisms tend to be geological.
Human civilization is now having an impact on the biosphere of a violence probably never seen before. The changes are faster than what geology, or even life, can accommodate.
Some will brandish the impact of the Yucatan asteroid, and claim that was worse; however that’s just a theory: the biosphere was clearly under stress at the time from the Deccan Traps eruptions, and had been under that stress for hundreds of thousands of years, if not millions. At its worst, the Asteroid was just the straw which broke the Camel’s back.
2015 will be the warmest year since the end of the Eemian, 115,000 years ago. So why are record low temperatures appearing just south of Iceland? Yes, record lows, lower than ever recorded.
While The Rest Of Planet Is At Record Warmth, Off Iceland, Record Colds Are Achieved!
That was fully expected, and a demonstration of Non-Linearity of the incipient global warming. A phenomenon is linear when it looks like a line. Global warming is not going up like a line, as some places are warming at a rate ten times higher than the average, and some regions are cooling (and some are cooling spectacularly, off Iceland and some seas around Antarctica, for reasons related to warming).
The Dryas events were extremely fast and pronounced cooling events which happened several times during the period 10,000 years to 15,000 Before Present. Some lasted around a millennium, others, just a century. They vanished as fast as they came. They are named after a tundra flower, the Dryas. In Scandinavia forests were replaced by tundra graced with Dryas (hence the name). In Britain, average temperature collapsed to minus 5 degree Celsius, and glaciers formed at elevation.
These spastic events of drastic cooling, while, overall, de-glaciation was going on, long remained a mystery. Overall, the great glaciation which had brought glaciers down to New York, was on its way out, the planet was globally, irresistibly warming. So why would temperatures collapse in some places around Greenland by 15 degrees Celsius? The solution to the Dryas events’ spastic glaciation riddle? The same as always! Warming is non-linear.
What’s the theory? The details are uncertain, but we know that the Gulf Stream (aka the North Atlantic “Conveyor”) shorted, literally: analyses of deep sea sediments have shown this. The conveyor sends an enormous current of warm tropical waters northward.
When the warm tropical waters become very cold between Iceland and Spitzbergen, they sink to the bottom of the sea, and head south. This sinking, plus the pushing by trade winds in the tropics, is what provides the energy of the Gulf Stream.
However, if the warm tropical waters are capped by a very cold, but light sweet(er) water lid, they will get cold early, and sink before Iceland. This is what happened in the Dryas events.
And It Is Happening Again, Albeit On A Smaller Scale.
Was it in response to a sudden influx of fresh water from Lake Agassiz and deglaciation in North America, and Greenland? Sudden freezing there would have removed the freshwater lid, hence the brutal switchback to warming after the brutal cooling. By the way, the sea level rising speed responded quickly, by a factor of three. After the typical Dryas cooling, oceanic rise rebounded to 18 millimeter per year right away (this shows that those who expect a slow rise of sea level rise are deluding themselves, or, more to the point, are trying to delude us!)
Nowadays a Dryas-like mechanism would have to rest on the melting of Greenland alone (that’s the only place with significant ice). This is, of course, insufficient, but summer 2015, cool and rainy over the northern North Atlantic is evidence that the effect is on. Scientific analysis confirms it. See: “Exceptional Twentieth Century Slow Down of Atlantic Ocean Overturning Circulation” (Nature, 23 March, 2015).
The exact nature of what is going on at this point is a matter of debate among experts. What is sure is that something is going on.
The Atlantic Conveyor Is A Subtle Thing, Yet Dominates Glaciation In The Arctic.
A similar situation beckons in Antarctica, where ice shield melting creates a freshwater lid all around which in turn freeze, extending the ice cap in the Austral winter.
When considering nonlinearity, subtlety and surprises are of the essence. This is true in physics, as it is in psychology, history, or politics.
And the morality in all this? The USA has played god. The European Union made a honest to goodness effort to reduce CO2 emission, while the USA, paying lip service to the opposite of what it was doing went right ahead, with its factory, the Plutocratic Republic of China, to use and abuse fossil fuels as never before.
So now what? Is god still American, as usual? At first it seems so: the USA started to frack massively and massive amounts of fossil fuels were extracted from the USA’s generous soil. When American companies tried the same in Poland, it failed: the underground god (Pluto?) did not cooperate: Polish soil is adverse to fracking.
Here comes the punchline: sea level has been rising fast along the Eastern seashore of the USA. Actually, three to four times faster than the world average. That’s more than one centimeter per year.
Why? Imagine a traffic jam. Or rather a crash ahead: things come to a halt, cars, water piles up behind. Maybe the Washington politicians will soon have to learn to swim, and not just against the tide of world public opinion.
The USA is going to be punished with its own instruments. Meanwhile 20 countries formed the V20, a group of twenty countries whose existence is immediately threatened by global warming, although they caused it not.

Exploring the range of emotions felt and displayed by our dogs.
Like so many bloggers, I subscribe to the writings of many others. Indeed, it’s a rare day when I don’t read something that touches me, stirring up emotions across the whole range of feelings that we funny humans are capable of.
Such was the case with a recent essay published on Mother Nature Network. It was about dogs and whether they are capable of complex emotions. Better than that, MNN allow their essays to be republished elsewhere so long as they are fully and properly credited.
Exactly what emotions do dogs feel, and are they capable of all the same emotions as humans? (Photo: Pressmaster/Shutterstock)
Joy, fear, surprise, disgust, sadness. These are the basic emotions dogs feel that are also easy enough for humans to identify. But what about more complex emotions?
Many dog owners are convinced their dogs feel guilty when they’re caught misbehaving. In the same way, many owners are sure their dogs feel pride at having a new toy or bone. But it gets tricky when you assign these sorts of emotions to a dog. These are definitely emotions felt by humans, but are they also felt by dogs?
(see footnote)
Why we question the presence of complex emotions is wrapped up in the way we get to those emotions. The American Psychological Association explains, “Embarrassment is what’s known as a self-conscious emotion. While basic emotions such as anger, surprise or fear tend to happen automatically, without much cognitive processing, the self-conscious emotions, including shame, guilt and pride, are more complex. They require self-reflection and self-evaluation.”
Essentially we’re comparing our behavior or situation to a social expectation. For instance, guilt comes when we reflect on the fact that we’ve violated a social rule. We need to be aware of the rule and what it means to break it. So, can dogs feel guilt? Well, exactly how self-reflective and self-evaluative are dogs?
Among humans, children begin to experience empathy and what are called secondary emotions when they are around 2 years old. Researchers estimate that the mental ability of a dog is roughly equal to that of an 18-month-old human. “This conclusion holds for most mental abilities as well as emotions,” says Stanley Coren in an article in Modern Dog Magazine. “Thus, we can look to the human research to see what we might expect of our dogs. Just like a two-year-old child, our dogs clearly have emotions, but many fewer kinds of emotions than found in adult humans.”
In other words, if 18-month-old children can’t yet experience these emotions, and dogs are roughly equal to them in cognitive and emotional ability, then dogs can’t feel these self-reflective emotions either. At least, that’s what researchers have concluded so far.
Is that guilt or fear?
This little puppy might feel guilty for chewing on clothes, or he could just be worried about getting in trouble. The two aren’t the same emotion. (Photo: InBetweentheBlinks/Shutterstock)
The evidence for primary emotions like love and happiness in dogs abounds, but empirical evidence for secondary emotions like jealousy and guilt is sparse. And this is partially because it’s difficult to create tests that provide clear-cut answers. When it comes to guilt, does a dog act guilty because she knows she did something wrong, or because she’s expecting a scolding? The same expression can come across as guilt or fear. How do we know which it is?
“In wolves, it is thought that guilt-related behaviors serve to reinforce social bonds, as in primates, by reducing conflict and eliciting tolerance from other members of the social group. The same could be true of dogs, though their social groups would primarily include humans. The problem is that the display of the associated behaviors of guilt are not, themselves, evidence of the capacity to emotionally experience guilt… It may still be some time before we can know for certain whether dogs can experience guilt, or whether people can determine if a dog has violated a rule prior to finding concrete evidence of it.”
Guilt, and other secondary emotions, are complicated. That’s exactly why cognitive awareness and emotional capacity in dogs is still a topic under study. In fact, it’s an area that has grown significantly in recent years. We may discover that dogs have a more complex range of emotions than we’re aware of today.
Dogs are highly social animals, and social animals are required to navigate a range of emotions in themselves and those around them to maintain social bonds. It wasn’t so long ago that scientists thought that dogs (and other non-human animals) didn’t have any feelings at all. Perhaps our understanding of dog emotions is simply limited by the types of tests we’ve devised to understand their emotions. After all, we’re trying to detect a sophisticated emotional state in a species that doesn’t speak the same language.
There’s a lot we don’t know
Dogs experience a range of emotions, but researchers are still trying to figure out exactly what those emotions are. (Photo: Hysteria/Shutterstock)
Marc Bekoff makes the argument for leaving the possibility open. In an article in Psychology Today he writes, “[B]ecause it’s been claimed that other mammals with whom dogs share the same neural bases for emotions do experience guilt, pride, and shame and other complex emotions, there’s no reason why dogs cannot.”
Keeping the possibility open is more than just an emotional animal rights issue. There is a scientific basis for continuing the research. A recent study showed that the brains of dogs and humans function in a more similar way than we previously thought.
Scientific American reports that “dog brains have voice-sensitive regions and that these neurological areas resemble those of humans. Sharing similar locations in both species, they process voices and emotions of other individuals similarly. Both groups respond with greater neural activity when they listen to voices reflecting positive emotions such as laughing than to negative sounds that include crying or whining. Dogs and people, however, respond more strongly to the sounds made by their own species.”
Until recently, we had no idea of the similar ways human and dog brains process social information.
So do dogs feel shame, guilt and pride? Maybe. Possibly. It’s still controversial, but for now, there seems to be no harm in assuming they do unless proven otherwise.
