Artificial Intelligence (AI) technology can produce improved digital biomarkers of ageing and frailty via gathering physical activity data from smartphones and other wearables, a new study suggests. According to the researchers from the longevity biotech company GERO and Moscow Institute of Physics and Technology (MIPT), AI is a powerful tool in pattern recognition and has demonstrated outstanding performance in visual object identification, speech recognition and other fields. "Recent promising examples in the field of medicine include neural networks showing cardiologist-level performance in detection of arrhythmia in ECG data, deriving biomarkers of age from clinical blood biochemistry, and predicting mortality based on electronic medical records," said co-author Peter Fedichev, Science Director at GERO. "Inspired by these examples, we explored AI potential for'Health Risks Assessment' based on human physical activity," Fedichev added. For the study, published in the journal Scientific Reports, researchers analysed physical activity records and clinical data from a large 2003-2006 US National Health and Nutrition Examination Survey (NHANES). They trained neural network to predict biological age and mortality risk of the participants from one-week long stream of activity measurements.
You've probably heard of the term'night owls', who stay alert until the early hours, or'morning larks', who spring out of bed. But now a study suggests there are two more patterns of shut eye, with some people being'afternooners' and others'nappers'. Scientists discovered that while some people's energy levels peak in the mornings or evenings, others feel most'alive' between noon and evening. And some need a snooze between 11am and 3pm, according to a team of Russian researchers investigating sleep. The study was led by the Institute of Higher Nervous Activity and Neurophysiology of the Russian Academy of Sciences in Moscow.
It has long been the stuff of science fiction but now mind-reading machines may actually be here and they may not be invasive. Researchers from the Russian corporation Neurobotics and the Moscow Institute of Physics and Technology have found a way to visualize a person's brain activity as actual images without the use of invasive brain implants. The work has the potential to enable new non-invasive post-stroke rehabilitation devices controlled by brain signals as well as novel cognitive disorder treatments. In order to do achieve such applications, neurobiologists need to understand how the brain encodes information by studying it in real-time such as when a person is watching a video. This is where the new brain-computer interface developed by the researchers comes in.
It was a painful procedure that could prove fatal. But Bronze Age surgeons in southwest Russia drilled holes in the back of people's skulls to fulfill ritual needs, rather than for medical reasons, a new study suggests. While experts can't guess what the gruesome ritual may have been 6,000 to 4,000-years ago, they found most who had the painful procedure were of high social standing - and often survived. Ancient surgeons in southwest Russia drilled holes in the back of people's skulls (example shown)to fulfil ritual needs, rather than for medical reasons, a new study suggests Archaeologists from the German Archaeological Institute in Berlin, the Russian Academy of Sciences in Moscow, Ministry of Culture of the Stavropol Region and Moscow State University, studied the skulls of 13 people buried at seven ancient sites in southwest Russia. They all have holes or marks on their skulls in the same place – the middle of the back of the head – which is a particularly dangerous place to have surgery.
Valery Spiridonov, 31: Russian tech geek who runs an educational software company from his home east of Moscow. Because he has Werdnig-Hoffmann disease, a genetic disorder that wastes muscles and motor neurons, he is physically capable of little beyond feeding himself, steering his wheelchair with a joystick, and typing. The disease is usually fatal, and doctors expected him to be dead by now. Xiaoping Ren, 55: Chinese surgeon who, when he lived in the United States, was on the team that performed the first successful hand transplant. He practiced for it by switching pigs' forelegs, and he keeps in his office a bronzed pig ear that the transplant team sent him as a trophy.
