Dogs and play, and the lessons for us humans.

Part One of a stunningly interesting essay from Professor Marc Bekoff.

As a newbie yet-to-be published author I am technically at the stage of having a completed draft that Jeannie and a close friend are proof-reading. Then after corrections, it is going to be released to some ‘beta’ readers who will give me some early feedback. (Too scary to even think of just now!)

OK, with that admission out of the way, let me move on to my ‘draft’ chapter on play; in Part Four of the book. In researching what is known about the way that dogs play and what lessons there are for us humans, I came across an essay by Marc Bekoff, Ph.D. Marc is Professor Emeritus of Ecology and Evolutionary Biology at the University of Colorado, Boulder. His essay had been published in May on the website of Psychology Today. It was incredibly interesting and full of material for the book!

Within a few minutes of me sending Professor Bekoff an email requesting permission to include quotations in my ‘draft’ chapter, he had responded in the affirmative. I had also sought his permission to publish the essay here on Learning from Dogs. Again, a very quick, positive reply.

Thus with Marc Bekoff’s generous permission, here is his essay in full. (I’ve taken the decision to split this long essay into two parts.)

Finally, Professor Bekoff includes numerous ‘html’ links within his essay to other materials. I’ve cheated by saving quite some time adding those links but have underlined the linked phrase in question, apart from the very early chapters that do have ‘html’ links. Please go to the site of the original essay to explore further those links.

Butts and Noses: Secrets and Lessons from Dog Parks (Part One)

Dog parks are gold mines of information about the behavior of dogs and humans

Post published by Marc Bekoff Ph.D. on May 16, 2015 in Animal Emotions

I love going to dog parks. So, too, do dogs and their people. Dog parks are a fascinating recent and growing cultural phenomenon. Indeed, I go rather often to what I call my field sites, for that’s what they are, to study play behavior and other aspects of dog behavior including urination and marking patterns, greeting patterns, social interactions including how and why dogs enter, become part of, and leave short-term and long-term groups, and social relationships. I also study human-dog interactions and when I study how humans and dogs interact I also learn a lot about the humans. For example, I often hear how happy people are that their dogs are free to run here and there or free to be dogs when they’re at the dog park. Often, they say this while they’re constantly calling them back to them even when the dog is simply sniffing here or there or looking for a friend. They also call them to break up play when they think it’s gotten out of hand. You call this free?

Two works to which I often go when thinking about social dynamics at dog parks are Matthew Gilbert’s book titled Off the Leash: A Year at the Dog Park and Sonoma State University’s Patrick Jackson‘s essay called “Situated Activities in a Dog Park: Identity and Conflict in Human-Animal Space.” Linda Case writes about Dr. Jackson’s study and she is not a fan of dog parks because she feels they’re not safe and because “Dog park people frequently behave badly by not being responsible dog owners and by being inconsiderate and uncaring towards other people and their dogs.” We really need empirical studies on the safety issue. After having spent countless hours at dog parks I’ve never entertained drawing this conclusion, but there aren’t any detailed data on this topic of which I’m aware. However, on occasion, but hardly regularly, I’ve marveled at just how inconsiderate a very few people can be. But, as part of the gossip network among the other people, I often hear that a given person behaves like this even in non-dog park situations. On a few ocassions I’ve had a rather inconsiderate person ask me why their dog has bad manners and rather than get involved I call attention to some interesting dog-dog interactions.

Most people realize that “dogs are in” and countless scientific and popular essays (see also New Directions in Canine Behavior, Julie Hecht’s “Dog Spies,” and essays written for Psychology Today by writers including Mark Derr, Stanley Coren, Jessica Pierce, and yours truly) and books have been published in the past decade or so about these fascinating mammals. The bottom line is that a plethora of detailed data — and the database is rapidly increasing — clearly show that dogs are thinking, clever, and feeling sentient beings, and viewing them as sort of robotic machines is incredibly misleading and academically corrupt (please see this essay). This does not mean that they are “doggy Einsteins,” however, ample data from numerous different research groups around the world clearly show that dogs are rather complex and incredibly interesting mammals who deserve a good deal of further study. Perhaps even René Descartes would consider changing his views on nonhuman animals (animals) as unfeeling machines given the enormous amount of empirical evidence on sentience in animals.

Why do dogs do this and that? Canine confidential

“Why do dogs do this and that?” The purpose of this short essay, that can be conceived as a field guide to the extremely interesting and largely unknown world of the fascinating dogs with whom we share our lives, is to provide some lessons in dog behavior from observations and questions arising from visits to various dog parks, especially around Boulder, Colorado where I live. I see myself as “a naturalist in a dog park” and aim to show here, via a series of questions, what we know and don’t know about many different aspects of dog behavior. Dogs are often called social catalysts – icebreakers or lubricants — for social interactions with other dogs and they often open the door for pretty frank and wide-ranging conversations among familiar and unfamiliar humans. It always amazes me how dogs free up humans to talk about things they might be more reluctant to share in other venues including what they really think about their human “BFF’s — best friends forever” — and the infamous “3 p’s,” namely, pee, poop, and puke. Often when I get home and look at my notes I view them as “canine confidential.” So, what follows is a sampler of many “why” questions, including why dogs hump, why they sniff butts, genitals, and ears, why they play, and why they organize themselves the ways they do. There are also many “what” questions such as “What do they know?”, “What are they thinking?”, and “What are they feeling?” in different contexts. The list of questions is endless and I’m sure those that follow can easily mutate in many, many more.

People who are lucky enough to share their world with a dog often think they know it all. And, while they do know a good deal about what their canine buddy is thinking and feeling and what they want and need, there really are large gaps in the scientific database. As I mentioned above, there are numerous anecdotes about why dogs do this or that, and, taken together, they form their own pool of data. However, while the claim that “the plural of anecdote is data” applies in some cases, many mysteries still loom in what we actually know about the world of dogs.

Furthermore, often there is no single “right” answer to a question — even some of the most commonly asked queries — and that’s just fine. Dogs compose a highly variable group of mammals — I often say “the dog” doesn’t really exist — so it’s not surprising that just when we think we have a solid handle on what they’re thinking and feeling and why they do what they’re doing an exception or three arises. Surely, the early experience of individual dogs influences their later behavior. So, while we know a lot, people are often amazed by how little we know and that hard and fast answers can’t be given to some common questions.

Visiting dog parks can be wonderful educational experiences. Visits, some lasting hours on end each and every day, can be myth breakers and icebreakers, and also provide information about why dogs are doing this or that. People are always asking questions about why their dog is doing something and really want to know what we know. They also freely offer advice to other people about why their dog is doing something and how they can treat various problems such as shyness, aggressiveness, and why dogs ignore what their human is asking them to do. And, as I wrote above, dogs also are icebreakers – “social catalysts” the academics call them — and get people to talk with one another and to talk about things.

The questions below range from interests about basic dog behavior such as why do dogs stick their noses where they do, and why they play, bark, pee, eat turds, and roll on their back, to more lofty questions about whether dogs have a theory of mind and whether they know what they look like and if they know who they are. A good number of questions deal with dogs’ butts and noses, hence the title of this brief essay (motivated, of course, by the famous rock group, Guns N’ Roses). Butts and noses — including other “private parts” – figure into a number of the questions below. We all know dogs put their noses in places where we couldn’t imagine there would be anything of interest, and also place their active snouts, often on their first introduction, to other dogs and humans, in places that make us rather uneasy. We don’t greet friends or strangers by immediately licking their mouth or with a genital sniff or slurp. There also are many general questions that don’t center on anatomical features that figure largely in the world of the dog. I’ll answer each question briefly with what we know from various types of research, with some stories where they’re available, and note where we really need more information. It’s entirely possible that I have missed a given study (or studies) and I apologize for the oversights and look forward to hearing from readers.

While we know a lot about dogs, there are holes in the database, so the future is chock full of exciting research. Readers will discover that what we often take to be the gospel about dog behavior frequently isn’t all that well supported by published empirical research or even detailed observations. While good stories are interesting and can serve to stimulate more “controlled” research, in and of themselves they don’t constitute “data” as do detailed and more focused studies (I’ll suggest below that studies in dog parks may be more “ecologically relevant” than studies in laboratories and help to settle on-going debates among different research groups). In some ways, then, this essay is sort of a myth-buster and a fun way not only to learn about dogs but also to stimulate further research about dogs and dogs and humans. So, here we go.

Our beautiful bees.

Incredible, intimate portraits of bees.

While Jean and I no longer attend meetings of the Southern Oregon Beekeepers Association, the meetings are a little too far away for us, I still subscribe to their email updates. Thus that’s how I was informed of a most incredible set of photographs on the National Geographic website. Here’s how the article opens:

Researchers take advantage of photography technology developed by the U.S. Army to capture beautiful portraits of bees native to North America.

Text by Jane J. Lee

Photography by Sam Droege, USGS

Bees are the workhorses of the insect world. By transferring pollen from one plant to another, they ensure the next generation of the fruits, nuts, vegetables, and wildflowers we so enjoy.

There are 4,000 species of North American bees living north of Mexico, says Sam Droege, head of the bee inventory and monitoring program at the U.S. Geological Survey (USGS).

Only 40 of them are introduced species, including the European honeybee. (See “Pictures: Colored Honey Made by Candy-Eating French Bees.”)

Most of the natives are overlooked because “a lot of them are super tiny,” Droege says. “The bulk of the bees in the area are about half the size of a honeybee.”

The native species also go unnoticed because they don’t sting, he adds. They quietly go about their business gathering pollen from flowers in gardens, near sand dunes, or on the edges of parks.

The bee pictured above is a species of carpenter bee from the Dominican Republic known as Xylocopa mordax. It nests in wood or yucca stems, and is closely related to the U.S. species that chews through the wood in backyard decks.

Trust me when I say that to view these images, and more, in their breathtaking beauty you need to go here and revel in what you see and read. Plus, in the text above I didn’t include the many links that are in the Nat Geo site’s version – so go there!

The natural world is so deserving of man’s care and protection.

On your bike, Mrs. H.!

My dear wife takes to cycling.

Like most young boys I was on a bicycle at a very young age. Then once sufficiently old to drive a motor car that was the end of bike riding for almost forever. Except that a few months ago the argument for anaerobic exercise as a means of delaying the worst of all the ailments that come with an ageing body (and mind!) convinced me to get back on a bike. That was made a lot easier because a small group of close neighbours ride three times a week and that seemed an opportunity not to be missed.

Those same neighbours supported, and recommended, a local bike shop in Grants Pass and I have ‘borrowed’ this picture of the store from their website.

Views of the interior of Don's Bike Center, Grants Pass, Oregon. — Views of the interior of Don’s Bike Center, Grants Pass, Oregon.

Having now been riding an average of 35 miles a week for the last ten or twelve weeks, I can vouch for the benefits it is providing.

Logically, therefore, it was going to be much better if Jean could come with me, and the rest of the riding group, each week. But there was a small challenge: Jean had never ridden a bike in her life. Horses, yes! Bicycles, no!

Eric over at the bike centre lent Jean a two-wheeler to try but very quickly it was clear that Jean would not easily develop the confidence to ride on our local roads. The next suggestion from Erik was a tricycle! Not one that was designed in the days of Noah and his Arc but a modern model of the ‘recumbent’ design. In particular, one manufactured by Sun Bicycles. Here’s an image of the trike from the Sun’s website.

Thus it came about that last Friday Jean and I went over to Don’s Bike Center to collect her new bike.

Eric at the store checking that the bike was properly set up for Jean.

Then once home it was time for Jean to learn a number of very new skills. At first just by riding around our turning circle in front of the house.

Then trying out our quarter-mile driveway that includes a couple of steep gradients; well steep for a cycle rider!

Another view of Jean getting to know her new bike here at home.

Then, deep breath, time to put on the safety helmet and go for a short ride on Hugo Road, our local road that runs past our property.

Slightly blurred image as I had the camera in my hand as I was riding behind Jean.

So all’s well that ends well!

Jean coming up the road towards the driveway entrance!

I will embarrass Jean by saying to my dear readers that Jean is already getting familiar with riding her trike and it won’t be too long before our riding group will be increased by one Mrs. Handover on her bike!

The things we do to stay healthy in our increasing years!

Sharing Ideas.

There’s no limit to learning.

I can’t recall how but recently I came across an online source of analysis, ideas and research that calls itself The Conversation. In their folder How we’re different, (in part) they explain:

The Conversation US launched as a pilot project in October 2014. It is an independent source of news and views from the academic and research community, delivered direct to the public.

Our team of professional editors work with university and research institute experts to unlock their knowledge for use by the wider public.

Access to independent, high quality, authenticated, explanatory journalism underpins a functioning democracy. Our aim is to promote better understanding of current affairs and complex issues. And hopefully allow for a better quality of public discourse and conversation.

We aim to help rebuild trust in journalism. All authors and editors sign up to our Editorial Charter. All contributors must abide by our Community Standards policy. We only allow authors to write on a subject on which they have proven expertise, which they must disclose alongside their article. Authors’ funding and potential conflicts of interest must also be disclosed. Failure to do so carries a risk of being banned from contributing to the site.

The Conversation launched in Australia in March 2011 and the UK in May 2013.

So with no further ado, and within the terms of The Conversation, may I share:

What does it mean to preserve nature in the Age of Humans?

Ben A Minteer, Arizona State University and Stephen Pyne, Arizona State University

Is the Earth now spinning through the “Age of Humans?” More than a few scientists think so. They’ve suggested, in fact, that we modify the name of the current geological epoch (the Holocene, which began roughly 12,000 years ago) to the “Anthropocene.” It’s a term first put into wide circulation by Nobel-Prize winning atmospheric chemist Paul Crutzen in an article published in Nature in 2002. And it’s stirring up a good deal of debate, not only among geologists.

The idea is that we needed a new planetary marker to account for the scale of human changes to the Earth: extensive land transformation, mass extinctions, control of the nitrogen cycle, large-scale water diversion, and especially change of the atmosphere through the emission of greenhouse gases. Although naming geological epochs isn’t usually a controversial act, the Anthropocene proposal is radical because it means that what had been an environmental fixture against which people acted, the geological record, is now just another expression of the human presence.

It seems to be a particularly bitter pill to swallow for nature preservationists, heirs to the American tradition led by writers, scientists and activists such as John Muir, Aldo Leopold, David Brower, Rachel Carson and Edward Abbey. That’s because some have argued the traditional focus on the goal of wilderness protection rests on a view of “pristine” nature that is simply no longer viable on a planet hurtling toward nine billion human inhabitants.

Given this situation, we felt the time was ripe to explore the impact of the Anthropocene on the idea and practice of nature preservation. Our plan was to create a salon, a kind of literary summit. But we wanted to cut to the chase: What does it mean to “save American nature” in the age of humans?

We invited a distinguished group of environmental writers – scientists, philosophers, historians, journalists, agency administrators and activists – to give it their best shot. The essays appear in the new collection, After Preservation: Saving American Nature in the Age of Humans.

Getting the chronology right, it turns out, matters less than we might think. The historian J R McNeill recounts the difficulty in fixing a clear start date for the Anthropocene. (Should it coincide with the late Pleistocene megafaunal extinctions? The rise of agriculture? The birth of the industrial era in the 19th century? The mid-20th century uptick in carbon emissions?) Wherever we peg it, McNeill argues, the future of nature preservation in America will increasingly be shaped by environmental traditions more congruent with notions of a human-driven world.

It’s a view shared by ecologist Erle Ellis. We’ve simply “outgrown” nature, Ellis argues, and so we have to become more comfortable within the “used and crowded planet” we’ve made. Andrew Revkin, author of the Dot Earth environmental blog for the New York Times, sounds a similar theme, arguing that the whole idea of “saving” a nature viewed outside the human presence is an anachronism. What we need instead, he suggests, is to focus on restoring a bipartisan politics able to cope with the challenges of living in and managing a human-driven world.

But all this talk of a more human-driven world and a species that is now “too big for nature” is dismissed by wilderness activist Dave Foreman, who spies a dark future awaiting us if we continue on the current path. Foreman condemns the vision of the “Anthropoceniacs” who he argues are promoting nothing less than the technological takeover of life on the planet. We need to remind ourselves, he writes, “that we are not gods.”

The need for humility courses throughout After Preservation. But it’s joined by an equally strong plea for pragmatism and more intelligent control. As science journalist Emma Marris writes, the desire to restrain ourselves in nature may ironically prove self-defeating if it means we can’t intervene to prevent present and future species extinctions. The biologist Harry Greene echoes this view with his manifesto to “rewild” the Anthropocene by actively introducing cheetahs, elephants, camels and lions to North America as proxies for the long-lost megafauna of the Pleistocene. It’s a rebooting of the wilderness idea – or maybe a wilderness 2.0 – for the technological age.

Regardless of how the Anthropocene debate plays out, environmental science and policy experts Norm Christensen and Jack Ward Thomas remind everyone how hard it is to implement whatever we want on the ground without unexpected consequences. Thomas, a former chief of the US Forest Service, describes how the unpredictability of ecosystems can result in cases in which the preservationist agenda becomes complicated as ecosystems change in surprising ways (for instance, when an unplanned growth in the barred owl population starts to displace the protected northern spotted owl in the Pacific Northwest).

Much of the discussion of the Anthropocene must hinge on values. But many of our authors conclude that it also needs grounding in a deeper and more nuanced understanding of history. As historians Donald Worster and Curt Meine point out, even if purist notions of the wilderness may no longer be realistic in the Anthropocene, it would be a grave mistake to jettison our environmental traditions and the commitment to protecting as much wildness as we can.

Even so, many suggest that nature conservation will have to evolve in order to reflect a more diverse constituency, an urban population not well served by the older preservationist values and images. Or, as ecologist Michelle Marvier and The Nature Conservancy’s Hazel Wong sum it up, “Move over, Grizzly Adams.”

The debate wasn’t settled at the end of After Preservation but we didn’t expect it to be. The argument has deep roots, as the writer and climate activist Bill McKibben reminds us in his coda to the book. And in one way or another, pragmatists and preservationists have been at odds since the birth of the American conservation movement in the late 19th century. The Anthropocene debate is only the most recent replaying of this enduring struggle.

What way forward? We think John McPhee probably got it about right nearly forty years ago in his memorable portrait of modern Alaska, Coming into the Country:

Only an easygoing extremist would preserve every bit of country. And extremists alone would exploit it all. Everyone else has to think the matter through – choose a point of tolerance, however much the point might tend to one side.

Our hope is that After Preservation will help us choose that point of tolerance as we puzzle through the environmental ethos of the Anthropocene. We’ve little choice: it’s going to be a challenge confronting the meaning and work of nature preservation for some time to come.

“No matter what people tell you, words and ideas can change the world.” Robin Williams

Protecting the brain.

The joys of growing ever more old!

Last Saturday, in a humorous post called Cognitive Ageing, I wrote:

Or put another way: I can remember everything except the things I forget.

Like many others of my age, the short-term memory is not as sharp as it used to be (not that I can remember when that was! 😉 )

Today’s post is to pass on a recommendation for a programme called Lumosity. It was recommended to me by my local doctor and I signed up in February of this year. Clearly, it is impossible to know, in a scientific way, how much good it has done me but instinctively I feel it has made a strong, positive difference. Let me quote from their website:

The Science Behind Lumosity

Neuroplasticity: how the brain is capable of change

Scientists have historically believed that once a person reaches adulthood, their cognitive abilities are immutable. But beginning in the early twentieth century, that theory has been contested by evidence suggesting that the brain’s abilities are in fact malleable and plastic. According to this principle of neuroplasticity, the brain is constantly changing in response to various experiences. New behaviors, new learnings, and even environmental changes or physical injuries may all stimulate the brain to create new neural pathways or reorganize existing ones, fundamentally altering how information is processed.

One of the most dramatic examples of neuroplasticity at work comes from a 2000 brain scan study on London taxi drivers (Maguire et al., 2000). In order to earn a license, London taxi drivers typically spend about two years learning to navigate the city’s serpentine streets. What mark, the study’s researchers wondered, did this long, rigorous period of training leave on taxi drivers’ brains? Under the scrutiny of fMRI scans, 16 male taxi drivers in this study were revealed to have larger hippocampuses than a control group of 50 healthy males of similar ages. And the longer the time spent as a taxi driver, the larger the hippocampus tended to be. As a brain area involved in memory and navigation, the hippocampus likely changed in response to the taxi drivers’ experiences.

Most instances of neuroplasticity-based changes in the brain are much more subtle. But in recent decades, it’s cases like that of the London taxi drivers that have inspired certain members of the scientific community to pursue the next logical step in research: rather than passively waiting to see how the brain might respond to circumstances, is it possible to direct that capacity for change, targeting improvements in specific key abilities?

The science of cognitive training seeks to answer this question. In 2013 alone, 30 cognitive training studies were registered on the government database ClinicalTrials.gov. Lumosity scientists, with the help of outside collaborators, contribute to this research effort: so far, 7 peer reviewed studies have been published using Lumosity as a cognitive training tool for diverse populations, including healthy adults, cancer survivors, elderly people, and children with a genetic disorder.

Maguire, E. A., Gadian, D. G., Johnsrude, I. S., Good, C. D., Ashburner, J., Frackowiak, R. S. J., & Frith, C. D. (2000). Navigation-related structural change in the hippocampi of taxi drivers. Proceedings of the National Academy of Sciences of the United States of America, 97(8), 4398-4403.

Clearly, without trying it out yourself, it’s difficult for me to convey the nature of the ‘games’ that are provided.

What I can do is to republish a review that appeared on the website MD-Health.

Does Lumosity Work?

Lumosity was designed by several leading neuroscientists, which adds an air of credibility to this popular site, and combines the perks of social networking with brain training technology that supposedly makes your brain function at a higher level. But do these brain training games really work? There is plenty of evidence to support and contract the claims made by this popular gaming website, so it is important to look at the facts before making this determination.

What is Lumosity?

Lumosity is a webpage that features several different brain training games. Players are encouraged to create a profile that allows them to track their progress and play certain games that target mental flexibility, memory, problem solving, speed and attention. The idea is that performing these tasks regularly will help “train” your brain to function more effectively.

How Does Lumosity Work?

The web page explains that Lumosity is based on neuroplasticity, which treats the brain like a muscle that needs to adapt when it is presented with new challenges. The idea here is that if you present your brain with harder challenges, the portion of your brain meant to help solve them will grow larger and more functional. Previously it was believed that neuroplasticity was only available in children with brains that were still developing, but recent science leads researchers to believe that this skill is also available for adults.

Lumosity depends on two basic elements when users create their training program. First, users need to use the program regularly. This is similar to creating a daily routine at your local gym to work and tone your muscles. Your routine will not be as effective if you do not stick with it. The second part of this training program depends on users using many different types of games. There are 35 different games available on Lumosity in addition to many different skill levels within these games. Players should use a variety of different games and increase the difficulty level over time to help ensure that they are continuing to challenge the mind. Creating your initial profile gives the player an opportunity to see what weaknesses they have so they can create a routine that is ideal for their situation.

Is Lumosity Effective?

There are several scientific studies that lead scientists to believe that the brain training activities at Lumosity do have an effect on the brain. A study at the University of Michigan found that adults that used brain training games for a regular amount of time saw an improvement in test scores for dual attention asks and memory games in multiple tests. A similar study at Brown University also saw adults exceeding expectations in brain performance after using brain training games to aid in their work. These programs were found to boost the working memory which helps users keep track of tasks they are currently performing.

The thing to remember when analyzing these results is that they came from laboratory conditions. These adults used Lumosity games for hours every day for several months. Users that do not work on a similar schedule will not see these types of results. There is a great deal of evidence that supports the idea that brain training games can help grow and develop the mind, but not necessarily any evidence that Lumosity and the brain training games available here are more effective than other training games that are on the market elsewhere. In general, keeping the mind active and challenging your mind to learn more advanced tasks and ways of thinking are healthy and can help you perform tasks more effectively, and if Lumosity helps you accomplish this, then it can be seen as a positive asset.

There was a review published in The Guardian newspaper back in April, 2013 from which this extract is offered:

According to the website for Lumosity, which devised these games and is one of the best-known internet providers of brain training, setting aside a few minutes each day to complete the above tasks can make you feel “smarter, sharper, and brighter”. By factoring in a mental workout in the same way that we might go to the gym to exercise, we get cleverer and our IQ rockets.

That, at least, is the idea. And there are lots of people who buy it. In recent years, brain training has become a multimillion-pound business with companies such as Jungle Memory, Nintendo and CogniFit developing a wide range of user-friendly neuroscientific puzzles for the average punter. Lumosity itself has grown by 150% year-on-year since its launch in 2005 and now reaches more than 35 million people worldwide. In January alone, the company’s mobile app was downloaded nearly 50,000 times a day and its revenue hit $24m (£16m).

Co-founded by Michael Scanlon after he abandoned his neuroscience PhD at Stanford University, California, the business also has an extensive research programme that studies the effects of computerised cognitive training as well as conducting experiments over the web.

I can also republish another article from the Lumosity website:

The Science Behind Lumosity

The scientific roots of the Lumosity program

Research has found that certain types of activities may impact the brain more than others (Mechelli et al., 2004; Gaser and Schlaug, 2003; Draganski et al., 2006). It’s believed that as an activity is repeated, the brain tends to fall back on the same set of existing neural pathways. To continue changing, the brain must be exposed to novel, adaptive experiences that challenge it to work in new ways.

Drawing on this idea, Lumosity is designed to give each person a set of exercises that challenge their cognitive abilities.

Lumosity “games” are based on a combination of common neuropsychological and cognitive tasks, many of which have been used in research for decades, and new tasks designed by an in-house science team. Working with experienced game designers, Lumosity neuroscientists have transformed these tasks into over 40 challenging, adaptive games.

Lumosity’s game-based training program is designed to expose your brain to gradually increasing levels of challenges, adapting game difficulty to your individual ability level. As your scores increase, you may encounter new or more difficult games. Modelled from the concept of a physical personal trainer, Lumosity pushes you to operate at the limits of your abilities and stay challenged.

Lumosity is not expensive and while it is impossible to be objective about the positive difference it is giving me I wouldn’t give up on it.

Now where did I leave my car keys???

We all have a story to tell.

Featuring David Isay and StoryCorps.

Jean and I were late back home on Wednesday evening and after our evening meal only had half-an-hour or so before it was time for bed.

We browsed some of the talks on TED (we don’t have TV) and noticed one that sparked our interest: Everyone around you has a story the world needs to hear. This is how the talk was introduced on TED.

Dave Isay opened the first StoryCorps booth in New York’s Grand Central Terminal in 2003 with the intention of creating a quiet place where a person could honor someone who mattered to them by listening to their story. Since then, StoryCorps has evolved into the single largest collection of human voices ever recorded. His TED Prize wish: to grow this digital archive of the collective wisdom of humanity. Hear his vision to take StoryCorps global — and how you can be a part of it by interviewing someone with the StoryCorps app.

It was a remarkable and fascinating talk and, thanks to YouTube, I’m able to share it with you.

I have no doubt that after watching Dave Isay’s talk you will want to go to the StoryCorps website.

Will return to this another day.

The Secret Life of Dogs.

Dogs watch us all the time and read our body language like a sixth sense.

Dogs watch us all the time and read our body language like a sixth sense. They also smell our bodies for changes.

Max smelt cancer in Maureen before any medical scans could pick it up. Dogs do this naturally and can be trained to pick up on tiny volatile chemicals given off by cancerous tumors. They can even be taught to alert diabetics to low blood sugar levels.

This dog can smell cancer

This is Frankie, a German shepherd mix. He can sniff out thyroid cancer in patients’ urine samples with 88% accuracy, according to a new study.

A trained scent dog accurately identified whether patients’ urine samples had thyroid cancer or were benign (noncancerous) 88 percent of the time, according to a new study by researchers at University of Arkansas for Medical Sciences (UAMS). The results were presented March 6 at the Endocrine Society’s annual meeting in San Diego.

Approximately 62,450 new cases of thyroid cancer will be diagnosed in the US this year, and around 1,950 Americans will die from the disease.

Techniques used to diagnose thyroid cancer include fine-needle aspiration biopsy, which involves the patient having a thin needle inserted into the thyroid gland in the neck to obtain a tissue sample. Donald Bodenner, MD, PhD chief of endocrine oncology at UAMS is the study’s senior investigator. Bodenner said:

Scent-trained canines could be used by physicians to detect the presence of thyroid cancer at an early stage and to avoid surgery when unwarranted.

Study-coauthor Arny Ferrando previously “imprinted,” or scent-trained, a rescued male German Shepherd-mix named Frankie to recognize the smell of cancer in thyroid tissue. Ferrando, who noted that dogs have at least 10 times more smell receptors than humans, said:

Frankie is the first dog trained to differentiate benign thyroid disease from thyroid cancer by smelling a person’s urine.

In this study, 34 patients gave a urine sample before they went on to have a biopsy of suspicious thyroid nodules and surgery. The surgical pathology result was diagnosed as cancer in 15 patients and benign thyroid disease in 19. These urine samples were presented one at a time to Frankie to sniff. Frankie had been trained to alert to a cancer sample by lying down, and turning away from a benign sample to alert the absence of cancer.

The dog’s alert matched the surgical pathology diagnosis in 30 of the 34 study samples, the investigators reported.

Bottom line: A new study by University of Arkansas for Medical Sciences (UAMS) researchers presented March 6, 2015 at the Endocrine Society’s annual meeting in San Diego described Frankie, a trained scent dog that accurately identified whether patients’ urine samples had thyroid cancer or were benign 88 percent of the time.

Turning over a beautiful leaf!

Yet another wonderful item sent across to me by neighbours Dordie and Bill.

Delicate Leaf Cuttings By Omid Asadi

My name is Omid Asadi and I currently live in Manchester, United Kingdom. I created this work with carving and cutting techniques on actual fallen leaves using a craft knife and a needle. I always try to create pieces with a message, not just beautiful art. Some of these messages or ideas come from my world view, poems, stories, global problems and philosophy. I’m also inspired by other artists’ and designers’ works.

Here’s the man in action.

Omidintro — I use a craft knife or scalpel and needle. It is not like a paper cutting because each part needs a certain pressure to cut. If I make a mistake, I destroy maybe hundreds of hours of work.

Leaf's Mind. I’m very attentive to beautiful fallen leaves. Suddenly, I started SEEING them, not simply looking at them. — **Leaf’s Mind.**

Carriage. I believe that we look at many things everyday, but don’t SEE them. For example, apples had been falling from trees for thousands of years, but only Isaac Newton truly saw that and, thanks to him, our lives have changed forever. — **Carriage.**

Feeding the souls of man and dog!

A most fabulous idea of sharing poetry in the wild.

One of the great advantages of having a dog, or nine, is that there are endless opportunities to go walking with them.

The other day, Jean and I became aware of the most wonderful idea: The Stanza Stones Walk. Here’s how that walk is explained on the website:

THE STANZA STONES PROJECT

The Stanza Stones Walk: An Alternative devised by Mick Melvin.

A fifty mile upland walk from Marsden to Ilkley visiting the six Stanza Stones carved with poems written by Simon Armitage.

Why create an alternative walk?

I have created this walk as an alternative to the 47 mile trail created by the team working with the Ilkley Literature Festival, not because it is my intention to denigrate the walk which was produced by the team. Far from it, the trail which they created is a fine outing and one that will satisfy the desires of most people wishing to visit the Stanza Stones.

My purpose was to devise an upland walk linking the stones which did not stick to recognised footpaths or to existing well-known walking trails. This has not always been possible, since I felt that it was necessary to follow the Pennine way or Millennium Way on occasions, in order to visit significant places of interest i.e. Blackstone Edge.

In addition I believe that considering the walk was motivated by literature, it should visit the places that inspired some of the area’s finest writers, Haworth and Mytholmroyd. My objective is to create six more circular walks to each of the stones which will be suitable for a day’s walking. These walks will be posted on the site as I complete them.

The seven Stanza Stones, each carved with a poem written by the poet Simon Armitage, are at locations which in general follow the Pennine watershed. The Stanza Stones project, which started at Ilkley Festival in August 2010, is focused on poems specially written by Simon stirred by his response to the Pennine Watershed and the relationship between the landscape and language of Yorkshire. The seven stones will form a permanent moorland trail across the watershed from Ilkley to Marsden the home town of the poet. The Stanza Stones poems are reproduced here by kind permission of Simon Armitage.

Isn’t that an incredibly wonderful idea!

Here’s a photograph of one of the stones bearing Simon Armitage’s poetry.

Blackstone Edge

The third Stanza Stone has now been completed at Cow’s Mouth Quarry near Blackstone Edge. The quarry is situated about 20 minutes walk along the track (Pennine Way) which starts at the White House pub. The Pub is on the A58 road between Halifax and Littleborough just beyond Blackstone Edge Reservoir. As you approach the quarry from the White House, watch for a small stone arched bridge spanning the catch water drain on you right about 75 yards before the crags. The path from the bridge affords a close up view of the face carrying the carving. The poem can also be seen from the main path if you continue along the gravelled track. A circular walk can be made if you continue on the track, taking the right turn to White Holme Reservoir returning to Blackstone edge and the White House on a good path over Byron Edge.

RAIN

Be glad of these freshwater tears,
Each pearled droplet some salty old sea-bullet
Air-lifted out of the waves, then laundered and sieved, recast as a soft bead and returned.
And no matter how much it strafes or sheets, it is no mean feat to catch one raindrop clean in the mouth,
To take one drop on the tongue, tasting cloud pollen, grain of the heavens, raw sky.
Let it teem, up here where the front of the mind distils the brunt of the world.

Whether or not you will ever have the chance to enjoy this walk, do go across to the Stanza Stones website and just revel in the poetry and the nature.

You can find out more about the poet, Simon Armitage, here on The Poetry Foundation’s website.

Surely a walk to feed the souls of both man and dog!
