I have two dog and I can say this is true on so many levels. Oh the cute looks they give me for more treats! Thou I do resist they still try. Yes both of them are spoiled for sure. In any event this article is from interestingengineering.com and written by Grant Currin:
"Scientists have figured out one of the big reasons that dogs are — in scientific terms — impossibly cute.
Researchers compared the facial muscles in dogs to those in wolves. They found that domesticated dogs have far more "fast-twitch" muscles than their close canine cousins. These muscle fibers contract quickly, allowing dogs a greater degree of short-term control over their facial expression.
That comes in handy when a pooch wants to ask for a morsel of food but, sadly, doesn't have the words.
Co-author Anne Burrows says the findings "suggest that having faster muscle fibers contributes to a dog’s ability to communicate effectively with people." The researchers presented their findings Tuesday at the Experimental Biology 2022 meeting in Philladelphia.
Humans and dogs really do have a special connection
Humans and dogs go way, way back. Researchers aren't sure when humans first started breeding especially friendly wolves, but it was probably more than 30,000 years ago. Researchers in Siberia recently found the 18,000-year-old remains of a puppy that might be the earliest dog ever uncovered (though it could also be a wolf).
Whenever their shared history began, humans and dogs have grown a bond sets the pair apart.
"Dogs are unique from other mammals in their reciprocated bond with humans," Burrows says. That relationship "can be demonstrated though mutual gaze, something we do not observe between humans and other domesticated mammals such as horses or cats."
In other words, dogs and humans can easily capture the other's attention — and find deep meaning — just from their facial expressions. That kind of communication across species is incredibly rare.
Humans changed canine facial muscles to more closely match our own
For this new study, the researchers compared the ratio fast-twitch and slow-twitch muscle fibers in certain facial muscles. Fast-twitch muscle fibers can contract quickly, but it doesn't take long for them to grow tired. In humans, sprinters tend to have more fast-twitch muscles in their legs. Slow-twitch muscles aren't as responsive, but they're more efficient and don't tire nearly as quickly. These are more common in marathon runners.
They analyzed fibers from two muscles (the orbicularis oris muscle and the zygomaticus major muscle) in gray wolves and several breeds of dogs.
The results were stunning. Muscles from the dogs' faces contained between 66 percent and 95 percent fast-twitch fibers. For wolves, that number was just 25 percent. Conversely, dogs had just 10 percent slow-twitch fibers in their faces while wolves averaged 29 percent.
Burrows says the findings say a lot about what humans desired in dogs.
“Throughout the domestication process, humans may have bred dogs selectively based on facial expressions that were similar to their own," she says. "[O]ver time dog muscles could have evolved to become ‘faster,’ further benefiting communication between dogs and humans.”
These results are another piece in the puzzle
This research isn't the first evidence that explains how dogs became so darn cute.
A few years ago, Burrows and other researchers reported evidence that dogs have a special muscle that enables them to raise their eyebrows in that special puppy dog sort way. They also compared the behavior of dogs and wolves, finding that dogs raise their eyebrows more often and far more intensely than wolves do.
Those facial movements make adult dogs look more like puppies and resemble "an expression that humans produce when sad," the authors write. "We hypothesize that dogs with expressive eyebrows had a selection advantage and that 'puppy dog eyes' are the result of selection based on humans’ preferences," they said.
As for the dogs, they're still waiting on that morsel of food."

I have lost a lot of faith with the Medical Community and the Governments over the last several years, but there are a few good things that can raise above the corruption and the pushing of drugs a new approach to heal people. The following is from www.gaia.com and written by Hunter Parsons that does not involve any drug or pushing an ineffective so called vaccine that the drug company is not held accountable in any way but they use sound! The use of sound can regrow bone tissue! Here is the story:
"The future of regenerative medicine could be found within sound healing by regrowing bone cells with sound waves.
The use of sound as a healing modality has an ancient tradition all over the world. The ancient Greeks used sound to cure mental disorders; Australian Aborigines reportedly use the didgeridoo to heal; and Tibetan or Himalayan singing bowls were, and still are, used for spiritual healing ceremonies.
Recently, a study showed an hour-long sound bowl meditation reduced anger, fatigue, anxiety, and ...
Not a fan of a Defense Agency studying Anti-Gravity and other Exotic Tech, but if the commercial world and make this technology cheap that will change our world yet again. The following is about three minute read and from www.gaia.com. The below was written by Hunter Parsons:
"Wormholes, invisibility cloaks, and anti-gravity — it’s not science fiction, it’s just some of the exotic things the U.S. government has been researching.
A massive document dump by the Defense Intelligence Agency shows some of the wild research projects the United States government was, at least, funding through the Advanced Aerospace Threat Identification Program known as AATIP.
And another lesser-known entity called the Advanced Aerospace Weapons System Application Program or AAWSAP
The Defense Intelligence Agency has recently released a large number of documents to different news outlets and individuals who have filed Freedom of Information Act requests.
Of particular interest are some 1,600 pages released to Vice News, which ...
As our technology gets better we are discovering more about the history of mankind and pushing the timeline back further and further. The following article is from www.gaia.com and written by Michael Chary that discusses this new find that changes the historical timeline:
"Over the past decade, there have been a number of archeological revelations pushing back the timeline of human evolution and our ancient ancestors’ various diasporas. Initially, these discoveries elicit some resistance as archeologists bemoan the daunting prospect of rewriting the history books, though once enough evidence is presented to established institutions, a new chronology becomes accepted.
But this really only pertains to the era of human development that predates civilization — the epochs of our past in which we were merely hunter-gatherers and nomads roaming the savannahs. Try challenging the consensus timeline of human civilization and it’s likely you’ll be met with derision and rigidity.
Conversely, someone of an alternative...
Not sure if you have heard of a show on YouTube called "The Why Files". If not you should check it out it is interesting and has some humor with it on different subjects. Last weeks was on a different theory how the Universe works and how main stream Science is attempting to shut it down like is always seems to do if it goes aguest some special interest. Today it is akin to what happened to those who questioned the Earth was the Center of the Universe that main stream so called Science all believed during the Renaissance period, They called any theory that the Earth was not the Center of the Universe misinformation. Does this sound familiar today? People laughed and mocked people like Leonardo da Vinci, Nicolaus Copernicus, Georg Purbach as crack-pots, conspiracy theorists, nut-jobs and they were suppressed and even imprisoned for their radical thoughts and observations. Again it sounds like today in so many ways. In any event this is a good one to ponder and see even if a bad idea ...
Seemingly chaotic systems like the weather and the financial markets are governed by the laws of chaos theory.
We all have heard about chaos theory, but if you have not or have forgotten what chaos theory is well here you go from interestingengineering.com:
"Chaos theory deals with dynamic systems, which are highly sensitive to initial conditions, making it almost impossible to track the resulting unpredictable behavior. Chaos theory seeks to find patterns in systems that appear random, such as weather, fluid turbulence, and the stock market.
Since the smallest of changes can lead to vastly different outcomes, the long-term behavior of chaotic systems is difficult to predict despite their inherently deterministic nature.
As Edward Lorenz, who first proposed what became commonly known as the Butterfly Effect, eloquently said, "Chaos: When the present determines the future, but the approximate present does not approximately determine the future.""
You may have heard the term about chaos theory as a butterfly flaps its wings in Brazil,...
I for one have lost trust in Medical Doctors due to COVID and reflection that they seem to push pills for everything and untested so called vaccines that is using a unproven technology because the Government and the Medical Boards of the State told them to. There are a very few exceptions. Thus they do not address the key problem just prescribe more and more pills to keep you alive an sick longer for them and Big Phama to profit from you. Will AI do any better? Well that depends on what was used for the training of AI. If it also pushes pills and vaccines without question then you have the same problems noted above. However, if the AI Training includes all possible forms of treatment and they zero in on the right issues for the true problem then there is possibilities they would be way better than most of the current Medical Doctors today.
The following is from an article from interestingengineering.com and written by Paul Ratner:
