It turned out that predators attack more often during the full moon, and the exact cause of this phenomenon is not completely clear, according to a paper published in Frontiers in Marine Science. The researchers analyzed data on shark attacks from 1970 to 2016 from around the world and compared them with lunar phases. The results showed that sharks attacked more often if the illumination of the Moon exceeded 50%. During the new moon or the first quarter, sharks attacked less often. And during the full moon, when the illumination of the moon was 100%, the predators were the most active. Great white sharks hunt close to the surface of the water, so lighting is of great

“When people ask me now whether it is necessary and worth diving, I urge maximum caution. Any mass gatherings of people are undesirable now. If they can be avoided, it is better to avoid them,” Metropolitan Hilarion said on the air of the Church and the World program on the Rossiya-24 TV channel, adding that “the virus has not gone away from us.” He called on believers to devote their time to “increase their immunity, vaccinate those who have not done it yet,” and also prepare for a new possible wave of exacerbation of the disease, which experts warn about. Answering the question of whether it is correct to believe that absolution of sins occurs through immersion in the ice hole, the bishop noted that such a statement is incorrect. “There is no absolution of sins through immersion in the baptismal font. Absolution of sins takes place in the sacrament

View this post on Instagram Publication from Research News (@research_news) The first Homo sapiens fossils from East Africa turned out to be about 30 thousand years older than previously thought. The remains, known as Omo I, were found near the Omo River in Ethiopia in 1967. The study of the partially preserved skull and several other bones showed that the ancient hominid possessed the features of a modern man — a high spherical vault of the skull and a characteristic chin. Scientists assumed that it was about 200 thousand years old, but this dating was considered not entirely accurate. Prehistoric bones were found in an area of high volcanic activity, so scientists tried to date volcanic ash in the layers from which the remains were extracted. However, radiometric methods worked inaccurately because the ash was too fine-grained. In a new study, scientists have been trying for about 4 years to date

Proteins with the ability to bind metals may be responsible for the origin of life on Earth. This conclusion was reached by researchers from Rutgers University in the USA. They wondered what properties define life as such, and came to the conclusion that living organisms are able to collect and convert solar, geothermal or other energy. From a molecular point of view, this means that the ability to transfer electrons is crucial for life. Since metals cope best with this task, and most of the biological activity is carried out by proteins, scientists decided to study more closely the proteins that bind metals. Having developed a new computational method, they compared all existing protein structures that bind metals to establish any common features. It turned out that the vast majority of currently existing metal-binding proteins are somewhat similar, regardless of the type of metal with which they are bound. “We

“The disease is now proceeding in a fairly mild form, and mortality has significantly decreased. While earlier, about 2% of those who fell ill died, now it is about 0.1%,” he said. The scientist noted that the virus has changed: to date, young people are becoming more ill with it, whose course of the disease is much easier. “Previously, the old versions of children were practically not touched. Young people endured it without noticing on their feet. Now young and middle-aged people get sick much more compared to the elderly,” Chumakov said. According to him, omicron mainly affects the upper respiratory tract, and also does not progress into pneumonia, as was the case with the original variants of COVID-19. Among the main manifestations of the omicron strain, Chumakov singled out: headache, runny nose, lack of loss of smell, cough and irritation in the nose. “It lasts from one day to
