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 Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon
On Friday, September 2, 2022, at the age of 93, American astronomer Frank Drake, who became one of the pioneers of the search for radio signals from extraterrestrial civilizations, died. He is also one of the creators of the records for the Pioneer and Voyager probes and the Arecibo radio message, according to the SETI… Continue reading Astronomer Frank Drake dies
Engineers from China and Germany have created the GhostTouch device, which allows contactless control of capacitive touch screens, taking advantage of their design features and susceptibility to electromagnetic interference. The device can accurately simulate taps and swipes in different directions on the screens of many popular smartphones without touching them. Despite the fact that the… Continue reading Engineers have learned to touch the touch screen without contact
The Voyager 1 team solved the problem of sending anomalous telemetry that had been coming from the probe for several months. It turned out that the cause of the failure was a faulty on-board computer, which was mistakenly assigned the operation of sending data. The problem has now been fixed, according to NASA's website. Voyagers… Continue reading NASA has fixed a glitch in Voyager 1's telemetry sending system.
Physicists combined the idea of a coherent ideal absorber (antilaser) with the concept of a degenerate resonator. The constructed optical system effectively absorbs light incident on it from various angles, and its operation has proven to be resistant to typical interference in optical communication lines. The study was published in Science. Absorption is an important… Continue reading An antilaser with a degenerate cavity turned out to be an excellent absorber
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
Embryologists again raised mouse embryos outside the mother's body. Recently, a group of Israeli scientists conducted a similar experiment and raised baby mice to the eighth day of development. Now the British have obtained approximately the same result – and at the same time verified that the Israeli embryo culture system ex utero works. The… Continue reading Scientists have grown another batch of artificial mouse embryos
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.
Japanese researchers have found that dogs cry when reunited with their owners after separation. This is due to an increase in oxytocin concentrations. The study was published in Current Biology. Dogs were domesticated and, through convergent evolution, learned to communicate with people through eye contact. For dogs, it plays a key role in the formation… Continue reading Oxytocin caused dogs to cry when reunited with their owner after separation
