Poor protein utilization contributes to neurodegeneration

Neurodegeneration can occur more quickly if nerve cells lack retromer proteins, which are responsible for breaking down toxic tau protein. This conclusion was reached by scientists who observed genetically modified fruit flies that produced human tau protein in 39 neurons of the eye. Tau protein itself already caused the death of nerve cells, and the… Continue reading Poor protein utilization contributes to neurodegeneration

The algorithm determined the mouse's pain level based on its muzzle expression

American scientists have developed a cloud platform that can assess the severity of pain in black laboratory mice. She analyzes the expression of the animal's face – the position of its nose, ears, whiskers and the degree of squinting of the eyes. Previously, researchers coped with this task manually, but, as the results show, the… Continue reading The algorithm determined the mouse's pain level based on its muzzle expression

Starlink satellites will be able to connect directly to regular smartphones

The new generation of Starlink satellites will allow anyone with a smartphone to connect to the mobile network and the Internet, even from places where there is no terrestrial coverage. The connection speed will be from two to four megabits per second. This was announced by SpaceX CEO Elon Musk and T-Mobile President Mike Sievert.… Continue reading Starlink satellites will be able to connect directly to regular smartphones

People used different parts of the brain when thinking about their inner circle and other people they knew.

People use different parts of the brain when they think about their family and closest friends and the rest of their social circle, scientists from Israel and the UK have found. In the first case, parts of the brain that are responsible for processing the mental state are activated, and in the second, those associated… Continue reading People used different parts of the brain when thinking about their inner circle and other people they knew.

Geneticists have found DNA similarities in unrelated twins

Spanish scientists have found that the strong similarity of people's faces is associated with DNA characteristics: half of the studied pairs of twins had exactly the same sequences in the genome. The researchers also collected data on the epigenome and microbiome of the mouth – but there were no noticeable similarities. The work was published… Continue reading Geneticists have found DNA similarities in unrelated twins

People didn't want to help others after a sleepless night and daylight saving time.

After a night of poor sleep or no sleep at all, people consider themselves less willing to help others, American scientists found in laboratory experiments and studying the sleep experience of people at home. It also found that after daylight saving time, when people potentially lose an hour of sleep, they donate less than they… Continue reading People didn't want to help others after a sleepless night and daylight saving time.

Loneliness in childhood predicted alcohol problems in adulthood

American psychologists have concluded that people who experienced loneliness in childhood (before the age of 12) tend to react more strongly to stress, which makes them more vulnerable to alcohol-related problems between the ages of 18 and 29. The results of the study were published in Addictive Behaviors Reports. A third of people in industrialized… Continue reading Loneliness in childhood predicted alcohol problems in adulthood

Physicists simulated militant Redditors with GameStop shares

European physicists used a large amount of data from the r/wallstreetbets subreddit, as well as the dynamics of securities prices, to understand the mechanisms of self-organization of a large number of people using the example of the scandal surrounding the unexpected rise of GameStop shares. The mathematical model they developed of a voter under the… Continue reading Physicists simulated militant Redditors with GameStop shares

A screen and automatic height adjustment were built into the desktop

Lumina has introduced a table with a built-in screen and wireless chargers. The screen allows you to display widgets in addition to your computer monitor, such as a calendar or Twitter feed. The table also has motors that change its height: manually at the user’s request or automatically so that he does not sit in… Continue reading A screen and automatic height adjustment were built into the desktop

Global climate change has played into the hands of most infectious diseases

An empirical systematic study conducted by American scientists showed that global climate change associated with the emission of greenhouse gases increases the prevalence of 58 percent of infectious diseases to one degree or another, and decreases it in only 16 percent. The report on the work was published in the journal Nature Climate Change. Continuously… Continue reading Global climate change has played into the hands of most infectious diseases
