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

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

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 genome of the “immortal” jellyfish has been sequenced

Spanish scientists have compiled a list of genes that are likely responsible for the “immortality” of the jellyfish Turritopsis dohrnii. To do this, they sequenced its genome and compared it with the genome of a jellyfish. Turritopsis rubra. It turned out that the “immortal” jellyfish, unlike its relative, acquired additional copies – up to eight… Continue reading The genome of the “immortal” jellyfish has been sequenced

Evolution forced mammals to recreate salivary proteins fifteen times

American bioinformaticians have discovered traces in the genomes of mammals of 15 independent occurrences of new proteins responsible for the viscosity of saliva. According to the findings of the authors of a study published in Science Advancesthe culprit is a region of the genome with a high mutation rate and selection pressure during the evolutionary… Continue reading Evolution forced mammals to recreate salivary proteins fifteen times

Ornithischian dinosaurs began living in packs already in the Jurassic period

Paleontologists analyzed samples of primitive ornithischians Lesothosaurus diagnosticus, found together in South Africa, and concluded that ornithischian dinosaurs lived in packs as early as the Lower Jurassic. This is the second earliest example of the social lifestyle of ornithischians. The study was published in the journal Palaeontology. Lesothosauruses were small omnivorous dinosaurs that lived in… Continue reading Ornithischian dinosaurs began living in packs already in the Jurassic period

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

Half of the cytoplasm was taken from a living cell and its transcript was sequenced

Swiss scientists have proposed and developed a method that allows them to decipher the transcriptome of individual cells without killing them. To do this, they performed a biopsy of the cytoplasm and sequenced the resulting genetic material. Scientists have used this technique to separate different types of morphologically similar cells and describe how the expression… Continue reading Half of the cytoplasm was taken from a living cell and its transcript was sequenced

The most expensive drug in the world is a new therapy for beta thalassemia. One injection costs $2.8 million

The United States has approved gene therapy for beta thalassemia, an inherited blood disease. The developer of the drug, Bluebird bio, claims that one injection is enough to, if not cure, then significantly improve the patient’s condition. But such an injection would cost $2.8 million. This is 700 thousand dollars more expensive than the Zolgensma… Continue reading The most expensive drug in the world is a new therapy for beta thalassemia. One injection costs $2.8 million

Americans have developed a clamshell monitor with two screens

The American company Mobile Pixels Inc presented a clamshell monitor: it consists of two separate screens, the angle between which can be adjusted. The monitor project was published on the Kickstarter crowdfunding platform; it has already raised almost $1.7 million. In most cases, people who are not satisfied with one monitor use a combination of… Continue reading Americans have developed a clamshell monitor with two screens
