Physicists have reproduced the chirping effect at the Kukulcan Pyramid

Colombian physicists have reproduced the unusual acoustic effect observed at the Temple of Kukulcan, located on the Yucatan Peninsula in Mexico. The echo of hand clapping at the base of the pyramid resembles the chirping or chirping of a bird. Simulations showed that this effect occurs due to the addition of many waves reflected from… Continue reading Physicists have reproduced the chirping effect at the Kukulcan Pyramid

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

Astronomers have limited the lifetime of the first “intra-Venus” asteroid

Astronomers presented the results of studies of the recently discovered asteroid Ailohchahnim, whose orbit lies entirely within the orbit of Venus. It turned out that the body has a diameter of 1.7 kilometers, it can be classified as a silicate asteroid and in 1-2 million years it can collide with the inner planets or even… Continue reading Astronomers have limited the lifetime of the first “intra-Venus” asteroid

Astronomers have found the best candidate for an ocean exoplanet

Astronomers using ground-based and space telescopes have confirmed the discovery of the super-Earth TOI-1452b around a red dwarf. According to scientists, it is best described by a model of an exoplanet with a global water ocean, the mass of which makes up 22 percent of the total mass of the planet. It is expected that… Continue reading Astronomers have found the best candidate for an ocean exoplanet

Quantum walks of atoms helped to search with the oracle

American physicists have experimentally realized quantum walks of neutral strontium-88 atoms in the cells of a two-dimensional optical lattice. The distribution and expansion of the atomic wave function in their work turned out to be in good agreement with the simple model up to a region of a hundred nodes. The scientists also demonstrated how… Continue reading Quantum walks of atoms helped to search with the oracle

Physicists have found the secret to the perfect pass in American football

American physicists have built the most accurate mathematical model of ball flight for American football and rugby to date. They found that the Magnus effect and the effect of the Earth's rotation have little influence on the outcome of a spiral pass, in contrast to the initial angle between the axis of the ball and… Continue reading Physicists have found the secret to the perfect pass in American football

A complete interactive atlas of the immune system has become publicly available

British and Swiss researchers have compiled an interactive electronic atlas of all interactions between cells of the immune system, mediated by their receptor and secreted molecules. The atlas is available on the Sanger Institute website, and a report on the work has been published in the journal Nature. The immune system differs from other body… Continue reading A complete interactive atlas of the immune system has become publicly available

Pigs had their organ functions restored an hour after death

American researchers have developed a system with which they were able to restore and maintain blood supply to organs in pigs for six hours an hour after death. At the same time, biochemical parameters were practically normal and stable, and organs were protected from degradation at the tissue, cellular and molecular level. The report on… Continue reading Pigs had their organ functions restored an hour after death

Paleoradiologists have denied the pregnancy of a mummified ancient Egyptian woman

Polish scientists have refuted the findings of the discovery of the first ancient Egyptian mummy of a pregnant woman, published last year. According to them, there is no evidence from CT scans and X-rays that one of the objects inside the abdominal cavity can be interpreted as a fetus. Moreover, the X-ray density of the… Continue reading Paleoradiologists have denied the pregnancy of a mummified ancient Egyptian woman

Manchester City Football Club and Cisco have developed a smart fan scarf

Manchester City Football Club, together with Cisco, have developed a smart fan scarf with a built-in sensor that monitors the wearer's heart rate, body temperature and emotional state. The new accessory will allow us to study the physiological and emotional reactions of spectators to events occurring on the field. The club's website reports on the… Continue reading Manchester City Football Club and Cisco have developed a smart fan scarf
