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

Mirror light nuclei differed from heavy ones in the frequency of nucleon pair production

Physicists from 13 countries presented the results of a study of the relative frequency of production of short-range two-nucleon correlations in the lightest mirror nuclei containing three nucleons. The data were obtained for a certain kinematic range during electron scattering by nuclei. The collaboration found that in light nuclei, neutron-proton pairs are formed approximately twice… Continue reading Mirror light nuclei differed from heavy ones in the frequency of nucleon pair production

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

The January eruption of the Tonga volcano triggered a 90 meter high tsunami.

The initial height of the tsunami caused by the eruption of the Hunga Tonga Hunga Ha'apai volcano on January 15, 2022 was 90 meters. These conclusions were reached by researchers from the UK, New Zealand, Croatia and Japan, who analyzed changes in atmospheric pressure and sea level and created nine models of a volcanic tsunami.… Continue reading The January eruption of the Tonga volcano triggered a 90 meter high tsunami.

Superfluorescence on single nanoparticles was obtained at room temperature

American physicists were able to induce anti-Stokes superfluorescence of one or several lanthanide-doped nanoparticles at room temperature. The rate of collective emission of ions turned out to be four orders of magnitude greater than ordinary luminescence. This research opens the way to the use of single nanoparticles in the creation of optical processors. The study… Continue reading Superfluorescence on single nanoparticles was obtained at room temperature

Food neurons found in visual cortex

American scientists have found that there are neurons in the ventral optic stream that respond to images of food. They recognized neural signals that, in standard fMRI data analysis, appeared to be drowned out by other nearby populations. Clusters of food neurons were found on both sides of the region of the vesiform gyrus, which… Continue reading Food neurons found in visual cortex

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

A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

Astronomers have concluded that the unusual narrow-band radio signal recorded in the direction of the Kepler-438 exoplanet system last year by the FAST telescope is not a technosignature, but is of anthropogenic origin. This is indicated by the polarization properties of the signal. A preprint of the work was published on arXiv.org. To answer the… Continue reading A candidate for an artificial radio signal from an Earth-like exoplanet turned out to be of terrestrial nature

An artificial finger was taught to identify materials by touch

Chinese and American engineers have developed an artificial finger with a sense of touch – it recognizes the material it touches and determines its roughness. This became possible thanks to triboelectric sensors and an algorithm that can determine touch parameters and material based on their readings. An article about the development was published in Science… Continue reading An artificial finger was taught to identify materials by touch

Embark taught an unmanned truck to present documents to police

The American company Embark showed tests of a system for interaction between an unmanned truck and the police. The car can recognize a police vehicle with flashing lights behind it and stop, and after the police officer approaches the truck, he can ask a remote operator for the code to the safe and retrieve documents… Continue reading Embark taught an unmanned truck to present documents to police
