The point at which the sun reaches its farthest point north of the equator is the Summer Solstice, well it is for the Northern Hemisphere. This occurs annually on June 20 or June 21, depending on your time zone.
Here in Southern Oregon, the moment of the Summer Solstice will be at 2:43 PM or 14:43 PDT on Saturday, i.e. today! For the United Kingdom it will be at 22:43 BST on the same day or 21:43 GMT/UTC.
A quick web ‘look-up’ finds that the word solstice is from the Latin solstitium, from sol (sun) and stitium (to stop), reflecting the fact that the Sun appears to stop at this time, albeit momentarily.
At the ancient stone circle of Stonehenge in Southern England, the prehistoric monument that took Neolithic builders an estimated 1,500 years to erect, for many years the Druids have celebrated the Solstice and, undoubtedly, will be doing so again.

There’s a good article over at EarthSky on this year’s Solstice. I would like to quote a little from it:
At the June solstice, Earth is positioned in its orbit so that our world’s North Pole is leaning most toward the sun. As seen from Earth, the sun is directly overhead at noon 23 1/2 degrees north of the equator, at an imaginary line encircling the globe known as the Tropic of Cancer – named after the constellation Cancer the Crab. This is as far north as the sun ever gets.
All locations north of the equator have days longer than 12 hours at the June solstice. Meanwhile, all locations south of the equator have days shorter than 12 hours.
and
Where should I look to see signs of the solstice in nature? Everywhere. For all of Earth’s creatures, nothing is so fundamental as the length of the day. After all, the sun is the ultimate source of almost all light and warmth on Earth’s surface.
If you live in the Northern Hemisphere, you might notice the early dawns and late sunsets, and the high arc of the sun across the sky each day. You might see how high the sun appears in the sky at local noon. And be sure to look at your noontime shadow. Around the time of the solstice, it’s your shortest noontime shadow of the year.
If you’re a person who’s tuned in to the out-of-doors, you know the peaceful, comforting feeling that accompanies these signs and signals of the year’s longest day.
Is the solstice the first day of summer? No world body has designated an official day to start each new season, and different schools of thought or traditions define the seasons in different ways.
In meteorology, for example, summer begins on June 1. And every schoolchild knows that summer starts when the last school bell of the year rings.
Yet June 21 is perhaps the most widely recognized day upon which summer begins in the Northern Hemisphere and upon which winter begins on the southern half of Earth’s globe. There’s nothing official about it, but it’s such a long-held tradition that we all recognize it to be so.
It has been universal among humans to treasure this time of warmth and light.
For us in the modern world, the solstice is a time to recall the reverence and understanding that early people had for the sky. Some 5,000 years ago, people placed huge stones in a circle on a broad plain in what’s now England and aligned them with the June solstice sunrise.
We may never comprehend the full significance of Stonehenge. But we do know that knowledge of this sort wasn’t limited to just one part of the world. Around the same time Stonehenge was being constructed in England, two great pyramids and then the Sphinx were built on Egyptian sands. If you stood at the Sphinx on the summer solstice and gazed toward the two pyramids, you’d see the sun set exactly between them.
How does it end up hotter later in the summer, if June has the longest day? People often ask:
If the June solstice brings the longest day, why do we experience the hottest weather in late July and August?
This effect is called the lag of the seasons. It’s the same reason it’s hotter in mid-afternoon than at noontime. Earth just takes a while to warm up after a long winter. Even in June, ice and snow still blanket the ground in some places. The sun has to melt the ice – and warm the oceans – and then we feel the most sweltering summer heat.
Ice and snow have been melting since spring began. Meltwater and rainwater have been percolating down through snow on tops of glaciers.
But the runoff from glaciers isn’t as great now as it’ll be in another month, even though sunlight is striking the northern hemisphere most directly around now.
So wait another month for the hottest weather. It’ll come when the days are already beginning to shorten again, as Earth continues to move in orbit around the sun, bringing us closer to another winter.
And so the cycle continues.
Indeed, so the cycle continues as it has for time immemorial!
Yesterday, (it was actually the 22nd February, 2014!) I published a post and called it Dogs and wolves – fascinating research. Then blow me down in yesterday’s online BBC News, there was an article headlined: Dogs’ brain scans reveal vocal responses This is how it opened.
Dogs’ brain scans reveal vocal responses
By Rebecca Morelle, Science reporter, BBC World Service
Pet dogs took part in the MRI scanning study.
Devoted dog owners often claim that their pets understand them. A new study suggests they could be right.
By placing dogs in an MRI scanner, researchers from Hungary found that the canine brain reacts to voices in the same way that the human brain does.
Emotionally charged sounds, such as crying or laughter, also prompted similar responses, perhaps explaining why dogs are attuned to human emotions.
Lead author Attila Andics, from the Hungarian Academy of Science’s Eotvos Lorand University in Budapest, said: “We think dogs and humans have a very similar mechanism to process emotional information.”
Eleven pet dogs took part in the study; training them took some time.
During the approximately 18–32 thousand years of domestication [1], dogs and humans have shared a similar social environment [2]. Dog and human vocalizations are thus familiar and relevant to both species [3], although they belong to evolutionarily distant taxa, as their lineages split approximately 90–100 million years ago [4]. In this first comparative neuroimaging study of a nonprimate and a primate species, we made use of this special combination of shared environment and evolutionary distance. We presented dogs and humans with the same set of vocal and nonvocal stimuli to search for functionally analogous voice-sensitive cortical regions. We demonstrate that voice areas exist in dogs and that they show a similar pattern to anterior temporal voice areas in humans. Our findings also reveal that sensitivity to vocal emotional valence cues engages similarly located nonprimary auditory regions in dogs and humans. Although parallel evolution cannot be excluded, our findings suggest that voice areas may have a more ancient evolutionary origin than previously known.
The canine brain reacted to voices in the same way that the human brain does.
“There were 12 sessions of preparatory training, then seven sessions in the scanner room, then these dogs were able to lie motionless for as long as eight minutes. Once they were trained, they were so happy, I wouldn’t have believed it if I didn’t see it.”
For comparison, the team looked at the brains of 22 human volunteers in the same MRI scanners.
The scientists played the people and pooches 200 different sounds, ranging from environmental noises, such as car sounds and whistles, to human sounds (but not words) and dog vocalisations.
The researchers found that a similar region – the temporal pole, which is the most anterior part of the temporal lobe – was activated when both the animals and people heard human voices.
“We do know there are voice areas in humans, areas that respond more strongly to human sounds that any other types of sounds,” Dr Andics explained.
“The location (of the activity) in the dog brain is very similar to where we found it in the human brain. The fact that we found these areas exist at all in the dog brain at all is a surprise – it is the first time we have seen this in a non-primate.”
Emotional sounds, such as crying and laughter also had a similar pattern of activity, with an area near the primary auditory cortex lighting up in dogs and humans.
Likewise, emotionally charged dog vocalisations – such as whimpering or angry barking – also caused a similar reaction in all volunteers,
Dr Andics said: “We know very well that dogs are very good at tuning into the feelings of their owners, and we know a good dog owner can detect emotional changes in his dog – but we now begin to understand why this can be.”
However, while the dogs responded to the human voice, their reactions were far stronger when it came to canine sounds.
They also seemed less able to distinguish between environmental sounds and vocal noises compared with humans.
About half of the whole auditory cortex lit up in dogs when listening to these noises, compared with 3% of the same area in humans.
Commenting on the research, Prof Sophie Scott, from the Institute of Cognitive Neuroscience at University College London, said: “Finding something like this in a primate brain isn’t too surprising – but it is quite something to demonstrate it in dogs.
“Dogs are a very interesting animal to look at – we have selected for a lot of traits in dogs that have made them very amenable to humans. Some studies have show they understand a lot of words and they understand intentionality – pointing.”
But she added: “It would be interesting to see the animal’s response to words rather than just sounds. When we cry and laugh, they are much more like animal calls and this might be causing this response.

The video presents the first study to compare brain function between humans and any non-primate animal. Scientists at MTA-ELTE Comparative Ethology Research Group in Hungary found that dogs and humans use similar neural mechanisms to process social information in voices. The fact that dogs can be trained to lie motionless during fMRI tests opens up the space for a new branch of comparative neuroscience.
The first study to compare brain function between humans and any non-primate animal shows that dogs have dedicated voice areas in their brains just as people do. Dog brains, like those of people, are also sensitive to acoustic cues of emotion, according to a study in the Cell Press journal Current Biology.
The findings suggest that voice areas evolved at least 100 million years ago, the age of the last common ancestor of humans and dogs, the researchers say. It also offers new insight into humans’ unique connection with our best friends in the animal kingdom, perhaps explaining how our two species have lived and worked together so effectively for tens of thousands of years.
“Our findings suggest that dogs and humans not only share a similar social environment, but they also use similar brain mechanisms to process social information,” said Atilla Andics of MTA-ELTE Comparative Ethology Research Group in Hungary. “This may help the successfulness of vocal communication between the two species.”
Andics and his colleagues trained eleven dogs to lay motionless in an fMRI brain scanner. That made it possible to run the very same neuroimaging experiment on dog and human participants — something that had never been done before. They captured both dogs’ and humans’ brain activities while they listened to dog and human sounds, ranging from whining or crying to playful barking or laughing.
The images show that dog and human brains include voice areas in similar locations. Not surprisingly, the voice area of dogs responds more strongly to other dogs, while that of humans responds more strongly to other humans. The researchers also noted striking similarities in the ways the dog and human brain processes emotionally loaded sounds. In both species, an area near the primary auditory cortex lit up more with happy sounds than unhappy ones. Andics said they were most struck by the common response to emotion across species.
There were some differences too: in dogs, 48 percent of all sound-sensitive brain regions respond more strongly to sounds other than voices. That’s in contrast to humans, in which only three percent of sound-sensitive brain regions show greater response to non-vocal versus vocal sounds.
The study is the first step to understanding how it is that dogs can be so remarkably good at tuning into the feelings of their human owners. “This method offers a totally new way of looking at neural processing in dogs,” Andics said. “At last we begin to understand how our best friend is looking at us and navigating in our social environment.”
Although this is the second time this has been shown it is so remarkable, and there may well be many who have not seen it!
I have been having some tiny problems mainly with the Apple Photos app and the good folks over at Ugly Hedgehog were incredibly helpful. This led to me taking my machine into Dick Webster Computers here in Grants Pass for a potential upgrade.
So I am going to republish some earlier posts for the next two days, which I hope will be long enough to come to a conclusion about whether this machine may be upgraded or whether I am looking at a new iMac.
Footnote:
I called in to Dick Webster, a good, local computer repair shop, earlier today. Took my iMac with me.
They told me that that particular iMac cannot have the RAM upgraded to 16GB but they could install a SSD. However, they looked up the Apple Photos app and said there were a number of complaints from others that it was freezing.
I was told to save my money, the iMac was perfectly good and to choose a photo editing application that supplied my needs.
My only outstanding query is whether all the relevant software programs, i.e. the photo editing apps, will run without any bother on 8GB.
We haven’t had a recall for some time but here’s one from Health Canada.
ooOOoo
Carnivora Dog and Cat Food Recall
June 15, 2020 — Health Canada is recalling Carnivora Fresh Frozen Patties for Dogs and Cats due to a possible contamination with E. coli O157.
E. coli O157 is a particularly dangerous strain of bacteria that can cause serious and life-threatening illness in both pets and humans after eating or handling the affected food.
What’s Recalled?
The recall includes 6 varieties of Carnivora brand raw pet food.
Approximately 1,803 packages of the affected products were sold nationwide in Canada between January 13, 2020 and June, 2020.
As of June 12, four cases of illness related to the recalled product have been reported.
About E. Coli Bacteria
E. coli O157 is a bacteria that can cause serious, sometimes life-threatening illness.
Some people infected with E. coli O157 do not get sick at all, though they can still spread the infection to others.
Common symptoms observed after infection include nausea, vomiting, headache, mild fever, severe stomach cramps, and watery or bloody diarrhea.
Most symptoms end within five to ten days.
Pregnant women, those with weakened immune systems, young children and older adults are most at risk for developing serious complications and might need hospitalization.
There is no real treatment for E. coli infections, other than monitoring the illness, providing comfort, and preventing dehydration.
People should contact their health care provider if symptoms persist or worsen with time.
What to Do?
Health Canada advises consumers to stop using any of the affected pet food products and contact the retailer where it was purchased from for a full exchange or refund.
U.S. citizens can report complaints about FDA-regulated pet food products by calling the consumer complaint coordinator in your area.
So soon after we welcomed Sheena, Ruby had a severe downturn.
Ruby had had one operation for the removal of a mast cell tumor back in February but we were advised by the vet that almost certainly it would grow back. Late on Saturday Ruby became very tired and went off her food and Jean and I were discussing having to take her to be put down on Monday (today).
Then overnight Saturday it was clear that her breathing was very laboured and on Sunday she was weak and struggling. It was time.
Being a Sunday we had no option other than to go to the Southern Oregon Veterinary Specialty Center, or SOVSC. We called them and they asked a few questions about Ruby and then told us to come straight over. They are at Biddle Road, Central Point and it took us 45 minutes to get there.
A little bit from their website:
Outstanding Team
Our team includes board certified specialists and highly trained doctors and staff, who have been chosen for their skill and expertise, as well as their compassion and dedication to veterinary medicine.
Then a couple of photographs from us.
oooo
Jeannie saying goodbye.
Ruby was the last of Jean’s Mexican rescues. She will be sorely missed!
