In 16 subsequent trials, Ebisu accurately copied her owner more than 81% of the time, the team reports this month in (see video, above). The fact that the cat used her paw and face to touch the box when her owner used her hand and face, respectively, indicates she was able to “map” her owner’s body parts onto her own anatomy, the team says.

Fugazza says only dolphins, parrots, apes, and killer whales have so far been shown to imitate people. Cats having the same ability, she says, suggests it may be widespread in the animal kingdom, evolving early in animal evolution. And even though the study was conducted on a single cat, Fugazza thinks it’s likely that most cats can imitate people. “I don’t think Ebisu was a genius.”

But Claudio Tennie, an ethologist at the University of Tübingen who has studied cognition in dogs and primates, is not impressed. He says it’s impossible to tell from the study whether cats have an innate ability to imitate humans, or whether the intensive “Do as I do” training gave them the skill. “We can train bears to ride motorcycles,” he says. “That doesn’t mean bears ride motorcycles.”

Physicist Jim Al-Khalili routinely deals with the strangest subject in all of science — quantum physics, the astonishing and perplexing theory of sub-atomic particles. But now he’s turning his attention to the world of nature. Can quantum mechanics explain the greatest mysteries in biology?

His first encounter is with the robin. This familiar little bird turns out to navigate using one of the most bizarre effects in physics — quantum entanglement, a process which seems to defy common sense. Even Albert Einstein himself could not believe it.

Jim finds that even the most personal of human experiences — our sense of smell — is touched by ethereal quantum vibrations. According to the latest experiments, it seems that our quantum noses are listening to smells. Jim then discovers that the most famous law of quantum physics — the uncertainty principle — is obeyed by plants and trees as they capture sunlight during the vital process of photosynthesis.

Finally, Jim asks if quantum physics might play a role in evolution. Could the strange laws of the sub-atomic world, which allow objects to tunnel through impassable barriers in defiance of common sense, effect the mechanism by which living species evolve?

Discovering chemical substances as possible chemical markers of life existence in Venus’s atmosphere via remote astronomical observations cannot be considered objective evidence of life existence on the planet, says Roscosmos Executive Director for Science and Advanced Programs Alexander Bloshenko. ‘Credible scientific data on that matter can be obtained only via contact explorations of the planet’s surface and atmosphere,’ he added.

Notably, the USSR was the only country to conduct regular explorations of Venus using on-planet stations. The first ever soft landing on another planet’s surface in the Solar system was performed in 1970 by the Venera-7 descent module. Several orbital missions and landings provided detailed data on the Venerian climate, soil and atmosphere composition. The Soviet Venera-13 spacecraft still holds the record as the longest active spacecraft on Venus remaining operational for 127 minutes.

A huge breakaway of the Soviet Union from its competitors in exploration of Venus contributed to the fact that USA called Venus a ‘Soviet planet’. Having recently analyzed the pictures of Venus captured by Soviet missions, scientists of the Russian Academy of Sciences claimed they discovered moving objects and even might be living. And it remains to be seen, whether these guesses are true.

Today, a program of complex exploration of Venus has been developed by Roscosmos in cooperation with the Russian Academy of Sciences. The program consists of several missions. Moreover, a decision was taken to implement the previously planned Venera-D mission including orbital and landing modules, as a national project without involving wide international cooperation. The complex explorations will also include soil and atmosphere samples, as well as exploring evolution processes on Venus that has purportedly suffered a climatic disaster connected with greenhouse effect that is much discussed on Earth today.

Although the SARS-CoV-2 virus has sickened more than 14 million people, bats contract similar viruses all the time without experiencing any known symptoms. Now, the newly sequenced genomes of six species spanning the bat family tree reveal how they’ve been outsmarting viruses for 65 million years. The findings are an “excellent starting point for understanding the superstar immune systems of bats,” says Laurel Yohe, a postdoc at Yale University who studies bat evolution and was not involved with the work. With more than 1400 species, bats are the second most diverse group of mammals on Earth. They live on every continent except Antarctica, and range in size from two to more than 1000 grams. They fly, they echolocate, and some live up to 41 years—a long time for animals of their size. They are also known to carry many different kinds of viruses, including coronaviruses, with no ill effects.

Newly sequenced genomes reveal the secrets of their “superstar” immune systems.

How cool would it be if we could one day regulate our atmosphere, control the climate and maybe even blast threatening asteroids into stardust? Well, to do those things would require A LOT of energy. Essentially, we’d have to be able to harness all the power from the Sun. According to the Kardashev scale that ranks planets according to their ability to harness the energy from their star and even their galaxy, that would make Earth a Type II civilization. What does that mean and how far away are we from achieving that level of uber energy capacity? You’ll have to tune in to find out as Peter and Richard welcome back Michio Kaku, physicist and science communicator extraordinaire to help us better understand “What If we became a type II civilization?”

What has been shaping the human mind throughout the history of mankind? What is the difference between mind and consciousness? What links quantum physics to consciousness? What gives rise to our subjective experience? What drives our accelerating evolution?

If you’re eager to familiarize with probably the most advanced ontological framework to date or if you’re already familiar with the Syntellect Hypothesis which, with this series, is now presented to you as the full-fledged Cybernetic Theory of Mind, you should get this book two of the series which corresponds to Part II of The Syntellect Hypothesis: Five Paradigms of the Mind’s Evolution. This volume two contains some newly-introduced and updated material if compared with the originally published version and can be read as a stand-alone book. At the same time, it is highly recommended to obtain The Syntellect Hypothesis as the original coherent version of the same theoretical framework instead of waiting for all five books to come out and if you don’t need extra detailing.

Over the course of human history, from the first bonfire to today’s smartphones and hyperloops, we have designed tools, and tools designed us back by shaping our minds. Technology isn’t just something outside ourselves, it’s an innate part of human nature, like sex, sleeping or eating, and it has been a major driving force in evolution. Tool using, along with language, bipedalism, and cooking (quite literally) is essentially what has made us human.

Colliding neutron stars were touted as the main source of some of the heaviest elements in the Periodic Table. Now, not so much …

Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds.

The research also reveals that current models can’t explain the amount of gold in the cosmos — creating an astronomical mystery.

A Chinese virologist who has alleged that COVID-19 was human-made in a lab in China released a report on Monday that she says backs up her explosive claim.

Dr. Li-Meng Yan, a former researcher at the Hong Kong School of Public Health, posted a paper on the open-access repository website Zenote, that she claims shows how SARS-CoV-2 could be “conveniently created” in a laboratory setting in six months.

The paper, co-authored with two others, is titled “Unusual Features of the SARS-CoV-2 Genome Suggesting Sophisticated Laboratory Modification Rather Than Natural Evolution and Delineation of Its Probable Synthetic Route.”

Summary: Glial cells not only control the speed of nerve conduction, but they also influence the precision of signal transduction.

Source: University of Münster

For the brain to work efficiently, it is important that a nerve impulse arrives at its destination as quickly and as precisely as possible. It has been long been known that the nerve fibres — also known as axons — pass on these impulses. In the course of evolution, an insulating sheath — myelin — developed around the axons which increases the speed of conduction. This insulating sheath is formed by the second type of cell in the nervous system — the glial cells, which are one of the main components of the brain. If, as a result of disease, myelin is depleted, this leads to neurological disorders such as Multiple Sclerosis or Morbus Charcot-Marie-Tooth.
