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

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.

Chinese scientists have deprived mice of a chromosome. And then another one

Chinese scientists have tested a new method of genome engineering: they have learned to stitch mouse chromosomes together. It turned out that if the chromosomes are not very large, then it is easy to glue them together and get a mouse with an odd number of chromosomes. Such animals can grow up healthy and fertile… Continue reading Chinese scientists have deprived mice of a chromosome. And then another one

Age and laziness increased the risk of developing cognitive dysfunction in dogs

Scientists from the USA have found out what is associated with the development of cognitive dysfunction in dogs. They included age, low level of physical activity, and a history of eye and ear diseases as risk factors. It turned out that lazy dogs risk almost 6.5 times higher than active dogs. The results of the… Continue reading Age and laziness increased the risk of developing cognitive dysfunction in dogs

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 Briton has assembled a “crossbow” with computer vision to throw LEGOs at your feet

British engineer and blogger Adam Beedle has developed a device that tracks a person's feet and throws sharp LEGO pieces under them. LEGO pieces are generally shaped like a parallelepiped, or simply put, a brick with sharp 90-degree angles. This is convenient for assembling a wide variety of structures, but often some parts of the… Continue reading A Briton has assembled a “crossbow” with computer vision to throw LEGOs at your feet

The mouse was turned into an aimbot on wheels

An American amateur engineer has created a mechanical aimbot that automatically aims in computer games. To make it virtually impossible to detect, he films the screen using a webcam and controls the sight not by software, but by hardware – by moving the mouse on the table using wheels. Aimbot is a program that automatically… Continue reading The mouse was turned into an aimbot on wheels

Cloned, edited beagles born in South Korea

Researchers in South Korea have obtained two beagle clones with a mutation likely associated with Parkinson's disease. To do this, it was necessary to first edit the dog's cells and then create embryos from them. Two embryos grew into full-fledged healthy puppies that carry the desired mutation and also glow in ultraviolet light. The work… Continue reading Cloned, edited beagles born in South Korea

Volunteers were asked to develop a space star shield for a hybrid observatory

The team of the HOEE hybrid observatory project for the study of Earth-like exoplanets invited everyone to participate in the development of a deployable space screen for shading the host stars of exoplanets. The structure, with a diameter of 100 meters, must be lightweight, durable and withstand flight into space and the conditions of the… Continue reading Volunteers were asked to develop a space star shield for a hybrid observatory

The artificial cytoskeleton was able to assemble into cell volumes

Scientists have created a synthetic cytoskeleton in the volume of real cells, says a study published in the journal Nature Chemistry. This design turned out to be capable of controlled assembly, depending on the presence of ATP or specific DNA fragments around it. In addition, the authors showed that the artificial cytoskeleton is potentially suitable… Continue reading The artificial cytoskeleton was able to assemble into cell volumes
