Picture: Novosibirsk Institute of Archeology and Ethnography The discovery was made this summer inside the mass burial of people from Odinov culture in Vengerovsky district of Novosibirsk region, Western Siberia. The small - about a palm size - statuette found in situ by the team of Novosibirsk Institute of Archeology and Ethnography had a mask depicting a bear made of a horse vertebrae. ‘This is without a doubt the find of the season, the find that any world museum from the Hermitage to the Louvre museum would love to exhibit’, said professor Vyacheslav Molodin, head of the Ust-Tartas 2 expedition.
Egyptian Medical Texts Medicine in ancient Egypt was understood as a combination of practical technique and magical incantation and ritual. Although physical injury was usually addressed pragmatically through bandages, splints, and salves, even the broken bones and surgical procedures described in the medical texts were thought to have been made more effective through magic spells. These spells were recorded in the medical texts of the time, written on papyrus scrolls, and consulted by physicians when needed. In the present day, most people would balk at the idea of visiting a doctor and having incantations muttered over them while they were rubbed with oil and fumigated with incense as amulets and charms were swung over their bodies, but to the ancient Egyptians, this was all simply a routine aspect of the medical practice.
Study shows brain flexibility, gives hope for natural-feeling neuroprosthetics Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought. Their new study, published March 4 in the advanced online publication of the journal Nature, shows that through a process called plasticity, parts of the brain can be trained to do something they normally do not do. The same brain circuits employed in the learning of motor skills, such as riding a bike or driving a car, can be used to master purely mental tasks, even arbitrary ones. Over the past decade, tapping into brain waves to control disembodied objects has moved out of the realm of parlor tricks and parapsychology and into the emerging field of neuroprosthetics. "This is something that is not natural for the rats," said Costa.
WHO (secretly) changed their definition of “Herd Immunity” Kit Knightly The World Health Organization has changed the definition of “herd immunity” on the Covid section of their website, inserting the claim that it is a “concept used in vaccination”, and requires a vaccine to be achieved. Both of these statements are total falsehoods, which is demonstrated by the WHO’s own website back in June, and every dictionary definition of “herd immunity” you can find. The European Library is now in Europeana Library records with digital media have been moved to Europeana, and you can also find the fulltext Newspaper collection. The European Library (TEL) was launched by the Conference of European National Librarians (CENL) in 2004 as the union catalogue of European national libraries and then became a web portal and open data hub for national library data in Europe. Its success led to the European Commission asking CENL to set up what later became Europeana. The European Library disseminated library data in a variety of ways to promote its wider use.
Spider Silk Is Strong Because It's Smart Spider silk is well known for some spectacular properties. It is stronger than steel and tougher than Kevlar yet flexible enough to be spun into a wide variety of shapes. New research shows that the material is not only strong but also smart. “Spider silk has a particular way of softening and then being stiff that is really essential for it to function properly,” said engineer Markus J. How to stay safe with a new fast-spreading coronavirus variant on the loose A fast-spreading variant of the coronavirus that causes COVID-19 has been found in at least 10 states, and people are wondering: How do I protect myself now? We saw what the new variant, known as B.1.1.7, can do as it spread quickly through southeastern England in December, causing case numbers to spike and triggering stricter lockdown measures. The new variant has been estimated to be 50% more easily transmitted than common variants, though it appears to affect people's health in the same way. The increased transmissibility is believed to arise from a change in the virus's spike protein that can allow the virus to more easily enter cells. These and other studies on the new variant were released before peer review to share their findings quickly. Additionally, there is some evidence that patients infected with the new B.1.1.7 variant may have a higher viral load.

Multiple candidates, each with a network of supporters, have organized themselves into various left- and right-wing clusters—like grassroots political teams working feverishly to reinforce a vision that bands them together. While scientists know that neurons in the brain anatomically organize themselves into these network camps, or clusters, the implications of such groupings on neural dynamics have remained unclear until now.
