Astronomer Frank Drake dies

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

Physicists were able to obtain acoustic frequency combs at 10 gigahertz

American physicists have manufactured a hybrid system from a nonlinear oscillatory circuit and an acoustic resonator connected by a piezoelectric contact. This combination made it possible to impart nonlinearity to acoustic modes at a frequency of 10 gigahertz. The authors were able to generate coherent acoustic frequency combs in their setup, which will help combat… Continue reading Physicists were able to obtain acoustic frequency combs at 10 gigahertz

Engineers have learned to touch the touch screen without contact

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

Ancient Tarim people were found among the ancestors of modern inhabitants of the Pamirs

Geneticists investigated the origins of speakers of Turkic and Indo-European languages ​​from Central Asia, for which they sequenced the DNA of 131 people and combined the data obtained with previously published ancient and modern genomes. It turned out that the origin of the Kyrgyz can be modeled from two components: the population of Xinjiang of… Continue reading Ancient Tarim people were found among the ancestors of modern inhabitants of the Pamirs

The population of the ancient Carthaginian city turned out to be genetically diverse

Paleogeneticists have read 30 genomes of ancient inhabitants of Tunisia, central Italy and Sardinia dating back to the Iron Age. In all regions, they found both descendants of more ancient local populations and immigrants from other territories. Thus, in the necropolis near the Carthaginian city of Kerkuan there were the remains of the descendants of… Continue reading The population of the ancient Carthaginian city turned out to be genetically diverse

Oscillations of water droplets on the ISS improve understanding of wetting

American physicists studied the natural vibrations of water droplets on hydrophobic substrates in microgravity conditions. To do this, they sent the necessary materials and equipment to the ISS. By filming the vibrations of the drops on camera, the scientists were able to confirm that their previously developed theory of vibrations of free drops works well.… Continue reading Oscillations of water droplets on the ISS improve understanding of wetting

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.

Oxytocin caused dogs to cry when reunited with their owner after separation

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

Pork protein corneas restored vision to 20 patients with keratoconus

Swedish scientists have developed corneal prostheses based on collagen from pig skin. In a pilot trial involving Indian and Iranian researchers, the prostheses helped restore vision to 20 patients with keratoconus. The report on the work was published in the journal Nature Biotechnology. The cornea is the anterior most convex part of the fibrous membrane… Continue reading Pork protein corneas restored vision to 20 patients with keratoconus

Gut bacteria helped bees communicate

Scientists from Germany and Switzerland have assessed the contribution of the gut microbiome to the social behavior of bees. It turned out that it makes bees interact with each other more often. Moreover, metamorphoses in insect behavior are accompanied by changes in gene expression and metabolite synthesis in the brain. The results of the study… Continue reading Gut bacteria helped bees communicate
