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

A 19th-century English farmer was accused of invading Australia by rabbits.

Biologists have found out who should be blamed for the environmental disaster caused by rabbits brought to Australia. Genetic analysis has shown that almost the entire local population of these animals descends from 13 wild and domestic individuals and their descendants, which were received from England in 1859 and released on his estate by settler… Continue reading A 19th-century English farmer was accused of invading Australia by rabbits.

Entomologists have reconstructed the chirping sound of a grasshopper found 150 years ago

Entomologists studied the grasshopper Prophalangopsis obscura, the only specimen of which was collected in northern India 150 years ago. As a result, it was possible to find out the frequency of its chirping. It turned out to be quite low, about 4.7 kilohertz. Such sounds carry far and can give away the location of the… Continue reading Entomologists have reconstructed the chirping sound of a grasshopper found 150 years ago

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

Gout attack temporarily increases risk of heart attack and stroke

A large observational study by British researchers found that the risk of heart attack and stroke temporarily increased after gout attacks. The results of the work were published in The Journal of the American Medical Association. Cardiovascular diseases (CVDs, primarily heart attack and stroke) occupy first place in the structure of global mortality – 18.6… Continue reading Gout attack temporarily increases risk of heart attack and stroke

Scientists from Australia and the USA have identified the “Somerton Man”

Researchers from Australia and the United States say they are closer to solving one of the main mysteries of Australian history. They were able to identify the “Somerton Man” – a man whose body was found in 1948 on a beach in the suburbs of Adelaide. For more than seventy years, it remained unknown who… Continue reading Scientists from Australia and the USA have identified the “Somerton Man”

The Himalayan bear was the result of hybridization between northern and southern bears

Geneticists have examined the nuclear DNA of six species of modern bears. It turned out that the Himalayan bears were the result of hybridization between the ancestors of modern northern (white, brown and baribal) and southern (Malayan and sloth) bears. These two lineages diverged about 5.91 million years ago and contributed approximately equally to the… Continue reading The Himalayan bear was the result of hybridization between northern and southern bears

Headphones with a built-in locator recognized facial expressions by the shape of the cheeks

American engineers have developed headphones that can recognize the user's facial expressions. To do this, a miniature sonar is built into each earphone, which, using sound echolocation, reads information about the movements of the lateral area of ​​the face, after which a machine learning algorithm restores the user’s facial expression in real time with high… Continue reading Headphones with a built-in locator recognized facial expressions by the shape of the cheeks

Lullabies and lisps have proven to be culturally universal

Representatives of 21 different cultural communities around the world communicate acoustically with babies and sing lullabies to them. This was discovered by American scientists who collected and analyzed an audio corpus of 1,615 recordings of singing and conversations addressed to young children and adults. It turned out that communication with babies has its own culturally… Continue reading Lullabies and lisps have proven to be culturally universal
