Those deeper ways of listening

How humans and animals communicate with each other has more than an edge of mystery to it!

We sleep with our bedroom door open to the main run of the rest of the house. Generally, all six dogs sleep in our bedroom unless it is a very warm night when some of them may choose the cooler tiled surface of the kitchen floor.

Cleo, our female German Shepherd, has a bit of a sensitive stomach and it is not unknown for her to need to be let outside in the middle of the night. Just a couple of nights ago her need for a ‘poo’ break came at 02:40!

But the point of this is that no matter how deeply I am sleeping, all it takes is a short, quiet whimper next to my side of bed and I am instantly awake. I need no time at all to know that Cleo has to be let outside from our bedroom door that opens out onto the deck. A few minutes later I hear her feet padding along the wooden boards of the deck and she is let back in to the bedroom.

Thus this demonstrates how well I understand her and in turn how well she acutely listens to me.

Just look at this photograph.

The connection, the intensity, of her attention towards me. And this was just from me pointing the camera at her and ‘click, clicking’ my tongue.

Moving on!

My introduction today was inspired by an article that I recently read on the Care2 site and that I want to share with you. Here it is.

Can Humans Understand When Animals Are in Distress?

By: Laura Burge   August 13, 2017

About Laura   Follow Laura at @literarylaura

Have you ever jumped at the sound of birds fighting or a squirrel screaming? Heard an animal make a sound somewhere nearby that made your heart race?

More than one hundred years ago, Darwin suggested that there was a universal understanding of certain animal vocalizations — a way of expressing emotion that went all the way back to the Earth’s earliest animals. Now, researchers are re-examining that theory, and they’re making some interesting headway.

In a study published in the journal “Proceedings of the Royal Society B: Biological Sciences,” researchers decided to explore the idea that animal vocalizations, including distress calls, might be recognizable across different species — and even into different animal classes.

Earlier research delved into whether or not humans could detect which emotion, or signal, another mammal was using, but this study is the first to examine other vertebrates as well. Amphibians and reptiles joined the club, and, perhaps surprisingly, humans did pretty well determining what these animals were trying to communicate.

The researchers primarily looked into whether or not people listening to certain animal sounds would be able to detect the level of arousal — high or low — that an animal expressed vocally. High arousal indicates an animal in distress, expressing desperate or negative screams, who might be calling out because of a fight, a predator in the area or another perceived danger. Scientists believe that these sounds are part of an old signaling system.

Researchers asked 75 college-aged individuals to listen to sounds from nine different species. In order to account for language differences, these people included English, German and Mandarin speakers.

Scientists collected 180 recordings of animal vocalizations, reflecting high or low levels of excitement, such as “the sounds of frogs in competition for mates, monkeys reacting to danger or ravens confronted by a dominant bird,” and included humans in that list, instructing actors to react neutrally or with different, heightened emotions while speaking Tamil.

The 75 people were then asked to identify which vocalization out of paired sounds from the same species represented the higher level of arousal.

In this study, the results showed that people identified the correct “emotion,” roughly speaking, better than expected by chance. Here is how the accuracy broke down across species:

  • Humans: 95 percent correct
  • Giant panda: 94 percent correct
  • Hourglass tree frog: 90 percent correct
  • African bush elephant: 88 percent correct
  • American alligator: 87 percent correct
  • Black-capped chickadee: 85 percent correct
  • Pig: 68 percent correct
  • Common raven: 62 percent correct
  • Barbary macaque (monkey): 60 percent correct

It seems strange that people were less able to identify the distress call of a monkey than a frog, but Harold Gouzoules, a bioacoustician and animal behavior expert at Emory University, posits that the monkey calls may have sounded less extreme in intensity than those of the other species, making it harder to tell the difference.

“Our study shows that humans are naturally able to recognize emotional arousal across all classes of vocalizing animals,” said Piera Filippi, who studies the evolution of cognition and communication at the Vrije University Brussels in Belgium.

This doesn’t mean that humans should feel confident in interpreting animal emotions or body language in general, though. Those behaviors can vary greatly, and humans are prone to misinterpretation and anthropomorphism. You wouldn’t, for example, want to assume a wolf baring its teeth is simply smiling at you.

Naturally, much remains to be studied in the effort to understand a wider range of animal emotions. Filippi hopes to repeat the experiment, but with the black-capped chickadees taking the place of the college-aged humans in interpreting the distress calls. It will be interesting to see if this understanding between humans and other animals goes both ways.

Could there be a beneficial reason for animals to understand each other’s distress calls? What do you think?

Just so long as too many different animals don’t all sound out distress calls at the same time around here!

 

Why Dogs Are Friendly

Yes, we know that they are but the science as to why this is nonetheless is fascinating!

Inevitably when you think about my cultural roots you would not be surprised to hear that I use the BBC News website as a key source of staying in touch with the world. But very rarely would I think of sharing a news item with you via these pages.

One of those rare exceptions greeted my eyes back on July 20th. It was an article published by Helen Briggs of the BBC under the Science & Environment news classification. I can’t imagine any reason why I can’t republish it here.

Why dogs are friendly – it’s written in their genes

By Helen Briggs – BBC News, 20 July 2017

Some wolves are more sociable than others.

Being friendly is in dogs’ nature and could be key to how they came to share our lives, say US scientists.

Dogs evolved from wolves tens of thousands of years ago.

During this time, certain genes that make dogs particularly gregarious have been selected for, according to research.

This may give dogs their distinctive personalities, including a craving for human company.

“Our finding of genetic variation in both dogs and wolves provides a possible insight into animal personality, and may even suggest similar genes may have roles in other domestic species (maybe cats even),” said Dr Bridgett vonHoldt of Princeton University.

The researchers studied the behaviour of domestic dogs, and grey wolves living in captivity. They carried out a number of tests of the animals’ skills at problem-solving and sociability.

Captive wolves gave humans only brief attention.

These showed that wolves were as good as dogs at solving problems, such as retrieving pieces of sausage from a plastic lunchbox.

Dogs, however, were much more friendly. They spent more time greeting human strangers and gazing at them, while wolves were somewhat aloof.

DNA tests found a link between certain genetic changes and behaviours such as attentiveness to strangers or picking up on social cues.

Similar changes in humans are associated with a rare genetic syndrome, where people are highly sociable.

Dr Elaine Ostrander of the National Institutes of Health, who was a co-researcher on the study, said the information would be useful in studying human disease.

“This exciting observation highlights the utility of the dog as a genetic system informative for studies of human disease, as it shows how minor variants in critical genes in dogs result in major syndromic effects in humans,” she said.

Wolves playing at Yellowstone.

Dogs were domesticated from wolves between 20,000 and 40,000 years ago.

New story for domestication of dogs

This process began when wolves that were tolerant of humans sneaked into hunter gatherer camps to feed on food scraps.

Over the course of history, wolves were eventually tamed and became the dogs we know today, which come in all shapes and sizes.

The finding of genetic changes linked to sociability in dogs shows how their friendly behaviour might have evolved.

“This could easily play into the story then of how these wolves leave descendants that are also ‘friendlier’ than others, setting the path for domestication,” said Dr vonHoldt.

The research is published in the journal, Science Advances.

Return to Predators!

The critical value of predators.

Not so long ago there was some discussion about how important it was for the natural way of things to include predators. I mentioned how this had been the topic of a post published some time ago in this place.

It was back in February, 2014 and I have republished it today.

The consequences of the reintroduction of wolves to Yellowstone National Park.

I have two people to offer my thanks to for today’s post: Suzann and Ginger. Both of them within hours of each other sent me an email recommending the following video. So, without further ado, here is that video. (Oh, would you believe this. The video was released on February 13th, 2014 and, at the time of me writing this post, has been viewed 1,453,345 times! Wow!)

When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable “trophic cascade” occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix.

If you want to read more on a general level, then my post on the 11th January, 2014, An echo in the hills! may be worthwhile. It included this from William Ripple, of Oregon State University:

Top dogs keep ecosystems in order

Many of these large carnivore species are endangered and some are at risk of extinction, either in specific regions or entirely. Ironically, they are vanishing just as we are learning about their important ecological effects, which is what led us to write a new paper in the journal Science to document their role.

From a review of published reports, we singled out seven species that have been studied for their important ecological role and widespread effects, known as trophic cascades. These are the African lion, leopard, Eurasian lynx, cougar, gray wolf, sea otter and dingo.

Based on field research, my Oregon State University co-author Robert Beschta and I documented the impact of cougars and wolves on the regeneration of forest tree stands and riverside vegetation in Yellowstone and other national parks in western North America. Fewer predators, we found, lead to an increase in browsing animals such as deer and elk. More browsing disrupts vegetation, reduces birds and some mammals and changes other parts of the ecosystem. From the actions of the top predator, widespread impacts cascade down the food chain.

Similar effects were found in studies of Eurasian lynx, dingoes, lions and sea otters. For example in Europe, absence of lynx has been closely tied to the abundance of roe deer, red fox and hare. In Australia, the construction of a 3,400-mile dingo-proof fence has enabled scientists to study ecosystems with and without dingoes which are closely related to gray wolves. They found that dingoes control populations of herbivores and exotic red foxes. The suppression of these species by dingoes reduces predation pressure, benefiting plants and smaller native prey.

In some parts of Africa, the decrease of lions and leopards has coincided with a dramatic increase in olive baboons, which threaten crops and livestock. In the waters off southeast Alaska, a decline in sea otters through killer whale predation has led to a rise in sea urchins and loss of kelp beds.

Predators are integral, not expendable

We are now obtaining a deeper appreciation of the impact of large carnivores on ecosystems, a view that can be traced back to the work of landmark ecologist Aldo Leopold. The perception that predators are harmful and deplete fish and wildlife is outdated. Many scientists and wildlife managers now recognise the growing evidence of carnivores’ complex role in ecosystems, and their social and economic benefits. Leopold recognised these relationships, but his observations were ignored for decades after his death in 1948.

Human tolerance of these species is the major issue. Most would agree these animals have an intrinsic right to exist, but additionally they provide economic and ecological services that people value. Among the services documented in other studies are carbon sequestration, restoration of riverside ecosystems, biodiversity and disease control. For example, wolves may limit large herbivore populations, thus decreasing browsing on young trees that sequester carbon when they escape browsing and grow taller. Where large carnivore populations have been restored – such as wolves in Yellowstone or Eurasian lynx in Finland – ecosystems appear to be bouncing back.

I am impressed with how resilient the Yellowstone ecosystem is, and while ecosystem restoration isn’t happening quickly everywhere in this park, it has started. In some cases where vegetation loss has led to soil erosion, for example, full restoration may not be possible in the near term. What is certain is that ecosystems and the elements of them are highly interconnected. The work at Yellowstone and other places shows how species affect each another through different pathways. It’s humbling as a scientist to witness this interconnectedness of nature.

My co-authors and I have called for an international initiative to conserve large carnivores in co-existence with people. This effort could be modelled after a couple of other successful efforts including the Large Carnivore Initiative for Europe, a non-profit scientific group affiliated with the International Union for the Conservation of Nature, and the Global Tiger Initiative which involves all 13 of the tiger-range countries. With more tolerance by humans, we might be able to avoid extinctions. The world would be a scary place without these predators.

Starting Out on The Meditation Journey

If meditation really works then we want to engage in it.

Those who watched the video that was the central component of yesterday’s post will not have missed the references by Ted Meissner that scientific, double-blind evidence shows that meditation offers benefits for us humans.

Both Jean and I are especially interested in learning more and, hopefully, finding an appropriate meditation group in our nearest town, Grants Pass.

We would also welcome feedback and advice from any of you good people who have trod this path before.

For example, when one conducts a quick internet search into the different forms of meditation there are dozens of websites that are returned in the search findings. Almost choosing one website at random, the Visual Meditation website declares there are 7 Types of Meditation.  As in:

  • Transcendental Meditation (TM)
  • Heart Rhythm Meditation (HRM)
  • Kundalini
  • Guided Visualization
  • Qi Gong
  • Zazen
  • Mindfulness

To my uneducated eye, not one of those types seems to accord with the type supported by the American Meditation Society:

OUR MISSION

  • To provide instruction in meditation as taught by the founder of AMS, Gururaj Ananda Yogi.
  • To preserve and share the universal teachings of Gururaj with integrity and wisdom.
  • To provide a place where those who wish to unfold the inner self may do so in the company of other like-minded people.

Back to the plot! For this post is about the science.

The following video seemed worthy of sharing with you.

I watched the first 10 minutes before deciding it should be shared. By the time this post is published Jean and I will have watched it to the end. [20:45 yesterday evening. Jean and I have just finished watching the Bob Roth video below. It was both fascinating and very helpful!!]

The Aspen Institute

Published on Jun 26, 2016

Published studies have documented the many physical and mental health benefits of meditation, including decreased pain, better immune function, less anxiety and depression, a heightened sense of well-being, and greater happiness and emotional self-control. Google Scholar turns up almost 700,000 research documents on meditation, among them imaging studies that show increased activity in brain regions associated with attention, a higher volume of grey matter, and lessened amygdala response to emotional stimuli. What actually happens in the brain when we meditate? Why is meditation so nourishing to the mind, body and spirit?

Perri Peltz, Interviewer
Bob Roth

But a search of the YouTube website using the search term “meditation science” brought up many other links to shorter videos.

I selected the following (2:23 mins) because it is presented by Ferris Jabr who is an Associate Editor with Scientific American magazine.

Bottom line to my way of thinking is that this is something worth committing to once we know much more about engaging in meditation.

Your experiences most welcomed.

(And, of course, when it comes to chilling out for hours regularly each day then there’s another thing we can learn from our beloved dogs! No better demonstrated than by Brandy yesterday morning in the following photograph!)

Give the Mexican Wolf a single chance!

Picking up on Annie

Remember Kristin’s guest post just two days ago? Annie’s Second Chance?

I’m sure you do.

Well the reason I am using that connection is because I want to share with you an email that was received yesterday.

Paul

The Mexican gray wolf (also called lobo) is the rarest subspecies of gray wolf in the world.  With just 113 individuals in the wild, this federally endangered species needs your voice now.

Tell the U.S. Fish & Wildlife Service (USFWS) to draft a science-based recovery plan for endangered lobos!

Despite recommendations by the US Fish and Wildlife Service’s own scientists, they have released a highly politicized Draft Mexican Wolf Recovery Plan, which we fear will lead these severally endangered wolves to extinction.

Ask the USFWS to revise their Draft Mexican Wolf Recovery Plan to protect endangered lobos instead of protecting special interests.

The draft recovery plan ignores science, gives special interests controlling power over recovery, and outlines criteria which will prematurely remove Endangered Species Act protections from the wolf.

Already plagued by mismanagement, poaching, and declining genetic diversity, the Mexican wolf needs your help more than ever.  We only have until the close of the comment period on August 29th to generate opposition to this flawed plan. Please submit your comment today to ask the US Fish and Wildlife Service to draft a recovery plan that’s based on science, not politics!

Thank you for your commitment to wildlife and wild places.

Sincerely,

What to see in the night sky in August

You all understand that this blog, while predominantly about our special doggie friends, never hesitates to wander away from matters canine if I think it will be enjoyed by all you good people.

You will also all appreciate that August is the month where in the USA, on August 21st, there will be a total eclipse of the sun.

The reasons why I didn’t hesitate to republish a recent post that was presented on Mother Nature Network.

What to see in the night sky in August

While the total solar eclipse is the highlight, there are other celestial fireworks to look forward to this month.

Michael d’Estries   August 1, 2017.

Welcome to August, a month defined by loud cicadas, pool parties, humidity and children fretting about an impending return to school. When it comes to celestial happenings, however, there is no larger star this month that our own moon. From a partial lunar eclipse to the first coast-to-coast solar eclipse in almost a century, the moon will be the cause of most eyeballs drifting towards the heavens over the next several weeks.

Below is a small sampling of some of the night and day celestial events to look forward to this month. Wishing you all clear skies!

The rise of the full Sturgeon Moon (Aug. 7)

The full Sturgeon Moon is so-named for the fish that are easily caught in August and early September. (Photo: Paul Kline/flickr)

August’s full moon, nicknamed the Sturgeon Moon, will rise for the U.S. Eastern Seaboard on the evening of Aug. 7 at 8:05 p.m.

The Sturgeon Moon gets its name from the species of fish native to both Europe and the Americas that is easily caught this time of year. Other nicknames include the Corn Moon, Fruit Moon and Grain Moon. In countries experiencing winter, such as New Zealand, native Māori called this full moon “Here-turi-kōkā” or “the scorching effect of fire is seen on the knees of man.” This reference is to warm fires that glow during the Southern Hemisphere’s coldest month.

Partial lunar eclipse (Aug. 7 & 8)

As a kind of consolation prize for missing out on this month’s total solar eclipse over North America, those living on the continents of Africa, Asia and Australia will bear witness to a partial lunar eclipse. Spectators in Europe will catch the tail end of the eclipse as the moon rises around 7:10 p.m. on Aug. 7.

This phenomenon occurs between two to four times a year when the moon passes through a portion of the Earth’s shadow. Because the shadow cast is more than 5,700 miles wide, lunar eclipses last much longer than solar eclipses. In some instances, totality can occur for as long as 1 hour and 40 minutes. As a reference, maximum totality for the Aug. 21 solar eclipse will top out a mere 2 minutes and 42 seconds. The longest, at over 7 minutes, won’t take place until the year 2186.

This month’s partial lunar eclipse is the last of the year. Next year, total lunar eclipses will take place in January and July.

Perseid meteor shower (Aug. 12)

Regarded as one of the best celestial light shows of the year, the Perseid meteor shower occurs from July 17 to Aug. 24 and peaks on the evening of Aug. 12.

The shower, sometimes creating as many as 60 to 200 shooting stars per hour, is produced as Earth passes through debris left over from the orbit of Comet Swift-Tuttle. This 16-mile-wide periodic comet, which completes an orbit around the sun every 133 years, has been described as “the single most dangerous object known to humanity.” This is because every instance of its return to the inner solar system brings it ever closer to the Earth-moon system. Though astronomers believe the comet bears no threat for at least the next 2,000 years, future impacts cannot be ruled out.

If the comet were to hit Earth, scientists believe Swift-Tuttle would be at least 27 times more powerful than the asteroid or comet that wiped out the dinosaurs. For now, you can take in the beauty of the debris from this harbinger of doom by looking north towards the constellation Perseus. Because the moon will be three-quarters full, you’ll need to search out a nice dark sky to escape any light pollution from urban environments.

Total solar eclipse (Aug. 21)

By far the biggest celestial event in ages, Aug. 21 marks the first time since June 1918 that a total solar eclipse will race from coast to coast across the United States. Cities and towns along the 72-mile-wide path of totality are preparing for an influx of visitors, with millions of Americans expected to drive to view the rare phenomenon. Those outside totality will still experience a show, with partial solar eclipses happening over much of North America. Regardless, everyone will want to invest in a pair of special solar eclipse glasses to avoid ruining your eyesight.

Total solar eclipses occur when the new moon moves between the Earth and the sun and casts its shadow on the planet. This shadow is comprised of two concentric cones –– the larger penumbra, which from Earth only shows the sun partially blocked, and the much smaller umbra, which blocks the sun completely. It is within this latter cone that totality will occur, giving spectators on the ground what’s considered by many to be a “once-in-a-lifetime” experience.

The Great American Eclipse will actually first start out in the Pacific (at this point, it will actually, unbelievably rise while completely eclipsed!), making landfall on the Oregon community of Lincoln Beach at 10:16:01 a.m. (PDT). From there, the moon’s shadow will continue to race across the U.S. The point of greatest eclipse, where the axis of the moon’s shadow passes nearest to the center of Earth, will take place in Hopkinsville, Kentucky and last 2 minutes and 40.1 seconds. In celebration of the event, the town has temporarily renamed itself “Eclipseville,” and expects anywhere from 55,000 to 150,000 tourists to visit in advance of Aug. 21.

The next total solar eclipse over the U.S. will take place on April 8, 2024.

New moon (Aug. 21)

Fresh after wowing the U.S. during the day with its solar theatrics, August’s new moon will give way to dark skies for the next several nights. This is the perfect opportunity to grab a blanket and head outside into the still-warm summer evenings to enjoy the heavens in all their glory. With some remnants of the Perseids still visible, it will also offer a chance to catch some of the faintest shooting stars.

Look for Earth’s shadow (All year)

Ever wonder what causes the beautiful bands of color in the eastern sky at sunset or the western sky at sunrise? The dark blue band stretching 180 degrees along the horizon is actually the Earth’s shadow emanating some 870,000 miles into space. The golden-red portion, nicknamed the “Belt of Venus,” is Earth’s upper-atmosphere illuminated by the setting or rising sun.

Now that you know about this phenomenon, choose a night or morning sometime to try and pick it out. You’ll need a western or eastern horizon that’s fairly unobstructed to get a clear view of our planet’s huge curved shadow.

Looking ahead to September

On Sept. 15, the Cassini spacecraft will end its 20-year mission to Saturn with a dramatic death dive into the ringed planet. (Photo: NASA)

As fall beckons, the biggest event next month will be the dramatic death dive of the Cassini spacecraft into Saturn. Taking place on Sept. 15, Cassini will make discoveries about Saturn right up until its fiery conclusion, with unprecedented photos and data captured and transmitted during its final moments.

ooOOoo

It is going to be quite a month!

Oh, and for those of you that want to know the timings of the eclipse over North America there is a useful reference site here, from which I republish the following table.

Eclipse Start & End: Local Time for US States

The eclipse will begin over the Pacific Ocean at 15:46 UTC, which corresponds to 8:46 am Pacific Time. It will reach the coast of Oregon at Lincoln City, just west of Salem, at 9:04 am local time. The eclipse will reach its maximum point here at 10:17 am.

From here, the Moon’s central shadow will move inland. The following table shows when the Moon will begin to move in front of the Sun and the moment it completely covers the Sun, as seen from some locations along the central path of the eclipse. All times are local.

Visiting the Vet – Jefferson’s heart!

Welcome to August!

July 13th. 11:00 The second case that I sat in on was Linda bringing in Jefferson.

Jefferson is an eight-year-old long-haired male Dachshund. Linda had decided to bring her dog into Lincoln Road because recently Jefferson had started coughing but only when he was pulling on his leash.

Linda added that Jefferson seemed to be chewing on a number of pine cones just now.

Jim examined Jefferson. First examining the dog’s lymph node and then listening to either side of the dog’s chest.

While everything sounded fine on Jefferson’s right side, Jim detected a very small heart murmur when listening to Jefferson’s left side.

Jim also noted that the lymph node was prominent but not enlarged. Dogs can get lymphoma.

Nothing arose to give cause for concern but in view of the chewing of pine cones, Jim thought that giving Jefferson an injection of ‘Lepto’ would be no bad thing.

11:20 All done!

I subsequently did a web search on ‘Lepto’ and came across this on the Vetstreet website: (in part)

It’s scary to think that a fun stroll through the woods or swim in a favorite watering hole can lead to a terrible illness, but it can –– for you as well as your dog. Leptospirosis is caused by a bacteria spread through soil, water, and the urine of infected animals, and if not caught early it can be deadly. There is a vaccine available for the most common subtypes of the bacteria that infect dogs, but it’s not always a recommended part of the routine vaccination protocol. Ask your veterinarian if the leptospirosis vaccine is right for your dog.

Overview

Leptospirosis is a potentially serious disease caused by the bacterium Leptospira interrogans. It affects dogs but can also infect a wide variety of domestic and wild animals as well as humans.

The organism is usually spread through infected urine, but contaminated water or soil, reproductive secretions, and even consumption of infected tissues can also transmit the infection. Introduction of the organism through skin wounds can also occur. Common carriers of the organism include raccoons, opossums, rodents, skunks, and dogs.

Help Stop the use of dogs for medical testing!

Sometimes I wonder about the human race!

Sorry for the outburst above but in the last ten minutes I read this over on Lady Freethinker’s blog: Sign: Pass Bill to Ban Cruel VA Medical Testing on Dogs It made me very angry!

It has to be shared with all you good people.

Sign: Pass Bill to Ban Cruel VA Medical Testing on Dogs

Posted by Nina Jackel | July 27, 2017

Every year in the U.S., tens of thousands of dogs are tortured and killed in gruesome medical experiments. They may be sliced, burned, mutilated, electrocuted or force-fed poisonous chemicals. Many of these experiments are carried out by the Department of Veteran’s Affairs (VA). But there is new hope for dogs brutalized in VA testing.

Congress has recently introduced the Preventing Unkind and Painful Procedures and Experiments on Respected Species Act (PUPPERS act) to ban cruel experiments on dogs by the VA. For the dogs’ sake, it is crucial that this legislation pass.

The bill follows haunting exposés by the White Coat Waste Project, which reveal VA labs committing atrocities such as inducing heart attacks in puppies, and giving dogs methamphetamine before killing them so their brains could be dissected.

Since the shocking abuse was exposed, progress has already been made. On July 26, the House passed an amendment to defund experiments like this for the next fiscal year. The amendment now awaits approval by the Senate. Defunding is an excellent step — but the next step is to ban the cruelty permanently.

Sign the petition to urge congress to pass the PUPPERS act to end VA torture of dogs for good, and then take action to ban ALL cruel experiments on animals.

Please go here to sign the petition.

Jean and I have signed.

Please, please, please add your name to this petition.

Thank you!

We are of the stars!

I so relate to this item from EarthSky News!

Long-term readers of this place will possibly recall that between April, 1989 and June, 1994 I lived on a Tradewind 33 sailing yacht Songbird of Kent. I have written before about those days.

Songbird of Kent. My home for five years.

When sailing at night when the sky is clear it is impossible not to feel deeply connected to the stars above one’s head.

My logbook for Songbird of Kent reports that at noon on Wednesday, 1st June, 1994, I departed the yacht harbour at Horta in The Azores bound for Plymouth, South-West England. Plymouth was 1,257 nautical miles (2,329km/1,447 statute miles) from Horta.

The logbook has an entry for the 6th June.

0400 Lat. 43 deg 25 minutes North, Long 22 deg 3 minutes West. Engine Off. Still no wind but must sleep after 19 hours of helming. 840 miles to run. Wind 2 knots from SW. Baro 1027 mb, Viz Good.

The visibility was wonderful and seeing the stars up in the night sky all around me, as in all 360 degrees about me, practically down to the horizon on this moonless night is an image still etched in my mind.

That’s why I want to republish this article that appeared on the blog EarthSky News yesterday.

We are galaxy stuff

By in Space | July 27, 2017

A new study – based on supercomputer simulations – reveals that each one of us may be made in part from matter that passes from one galaxy to another.

This image shows M81 (bottom right) and M82 (upper left), a pair of nearby galaxies where intergalactic transfer – transfer of materials between galaxies – might be happening. Image via Fred Herrmann.

Sagan famously said that we are made of star stuff. He meant the carbon, nitrogen and oxygen atoms in our bodies, as well as atoms of all other heavy elements, were created inside stars. Yet Sagan’s expression of this idea, which quickly became a cornerstone of popular culture, might not take the concept far enough. According to astrophysicists at Northwestern University, our origins are much less local than previously thought. In fact, according to their analysis – which they say is the first of its kind – we’re not just star stuff. We’re galaxy stuff.

This study is being published on July 26, 2017 (July 27 in the U.K.) by the peer-reviewed journal Monthly Notices of the Royal Astronomical Society.

The Northwestern researchers found that up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter. That is, atoms of carbon, nitrogen, oxygen and so on in our bodies may be created not just by stars in our own Milky Way galaxy, but by stars in far-flung galaxies.

They arrived at this conclusion using supercomputer simulations. The study required the equivalent of several million hours of continuous computing.

The simulations show that supernova explosions eject great quantities of gas from galaxies, which causes the atoms made inside stars to be transported from one galaxy to another via powerful galactic winds. According to their statement, intergalactic transfer is a newly identified phenomenon, which, they say, requires supercomputer simulations in order to be understood. According to these astrophysicists, this understanding is critical for knowing how galaxies evolve … and hence for knowing our own place in the universe.

Daniel Anglés-Alcázar is a postdoctoral fellow in Northwestern’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA). He led the study, and he said:

It is likely that much of the Milky Way’s matter was in other galaxies before it was kicked out by a powerful wind, traveled across intergalactic space and eventually found its new home in the Milky Way.

Given how much of the matter out of which we formed may have come from other galaxies, we could consider ourselves space travelers or extragalactic immigrants.

Space is vast. Galaxies are located at almost inconceivable distances from each other. So, Alcázar and his team said, even though galactic winds propagate at several hundred kilometers per CIERA second, the process of intergalactic transfer occurs over billions of years.

As always, this new research built on earlier studies. Northwestern’s Claude-André Faucher-Giguère and his research group, along with a unique collaboration called Feedback In Realistic Environments (FIRE), had developed numerical simulations that produced realistic 3-D models of galaxies. These simulations followed a galaxy’s formation from just after the Big Bang to the present day.

Anglés-Alcázar then developed state-of-the-art algorithms to mine this wealth of data. In this way, he and his team were able to quantify how galaxies acquire matter from the universe.

The scientists say the prediction of intergalactic transfer can now be tested. The Northwestern team plans to collaborate with observational astronomers who are working with the Hubble Space Telescope and ground-based observatories to test the simulation predictions.

Bottom line: Supercomputer simulations suggest that each one of us may be made in part from extragalactic matter. Hence, we are galaxy stuff.

Visiting the Vet – Hyperthyroidism

Lady Jessica isn’t feeling too well.

09:50 July 13th, 2017.

Jessica Louise is a 14-year-old cat that normally lives happily outside. But in recent times ‘Jessie’ has become very thin despite constantly eating and has now preferred to be inside the home even accounting for the fact of there being dogs in the house.

Jim’s pretty certain that he is looking at a cat with a hyperthyroid thyroid gland. No question that a blood test is needed and the blood sample is taken without delay.

The results are soon back and confirm that Jessie’s T4 readings of >8.00 mg/dL are very high, indeed beyond the upper limit of their testing equipment. Jim explains that the normal range for T4 is between 0.80 – 4.70 mg/dL.

The puzzled look on my face is seen by Jim and he takes a few minutes out to explain what a blood test accomplishes.

There are three parts to the blood test:

  1. The Complete Blood Count (CBC), that is the cellular part of the test.
  2. The chemistry of the blood, measuring the condition of the kidneys, liver, electrolytes, diabetic status as in blood glucose level, and more.
  3. The optional Part, a test for T4 Total Thyroxine level.

A very quick web search found this from which one reads:

Your dog or cat’s T4 (Total T4) is a useful screening test to detect an under-active thyroid gland (hypothyroidism) in dogs or an over-active one (hyperthyroidism) in cats. But total T4 levels are a considerably more accurate way to diagnose an overly active thyroid gland in your cat than an under-active thyroid gland in your dog.

Jim prescribes Methimazole. Once again, back at my desk a quick web search for Methimazole For Cats finds:

What is Methimazole?

Methimazole is used to treat hyperthyroidism in cats. It has largely replaced propylthiouracil in this treatment process since it has a lower incidence of adverse side effects. Methimazole requires a prescription from your veterinarian, and is sold per tablet.

(This is only one of many products found online!)

Jim weighs Jessie and finds that she is 4lbs 12 oz. Her weight should be in excess of 8 lbs.

The clinic protocol is that Jessie should not be seen until at least 45 days has elapsed. But Dr. Jim underlines that Jessie should be brought back in to the clinic before then if there is no weight gain soon or, especially, if Jessie continues to lose weight.

10:05 All done.

Good people, may I ask for your assistance.

Best explained by sharing part of a recent email sent to Yvonne D. who has offered her help with my book project. In past times, Yvonne was a Veterinary Technician.

Dear Yvonne,

My Visiting the Vet theme on Learning from Dogs has awakened within me the interest and passion to write my second book. Or, to put it more accurately, to switch away from the present theme that I have been struggling to get stuck into for months.

I spoke with Russel Codd at the clinic and he is really keen to support me.

The overall idea that is forming in my mind is to write a book that alternates, chapter by chapter, between observing the medical and clinical goings-on at a number of vet clinics in town, including specialist processes, surgery, cardiac, etc., and chapters that look deeply into the many different relationships that individuals have with their pets; primarily with dogs and cats.

I want to get into the ‘mindset’ of people who have pets in their lives across the whole range of feelings of those said people. From those who love their pets practically without any limit, to the homeless people (almost 100% men) whom one sees with a dog or two in tow alongside the highway. But also exploring those who seem so hateful. E.g. our pet sitter knows a man who threw his elderly dog away in some local woods. What causes someone to be like this? I want to find out!!

The book will be called: Of Pets, and Of People.

With very kind wishes,

Paul
