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

Nepenthes has adapted to use the energy of falling raindrops to capture victims

One species of Nepenthes, a carnivorous plant common in the jungle, has evolved a mechanism that allows it to use the energy of raindrops for hunting. A drop of water falls on the leaf-cover of the plant and sends the insect sitting on it straight into the trap. However, it turned out that the mechanism… Continue reading Nepenthes has adapted to use the energy of falling raindrops to capture victims

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

InSight station sends final selfie from Mars

The InSight automatic station sent to Earth the last selfie, composed of frames taken using a robotic arm. In the near future, it will be turned off forever, and in three months the station will complete its scientific program, according to NASA’s website. InSight has been operating on Mars for 3.6 years, becoming the first… Continue reading InSight station sends final selfie from Mars

Boeing CST-100 Starliner spacecraft embarks on second test flight

The American manned spacecraft Boeing CST-100 Starliner without a crew on board set off on its second test flight to the ISS. During its first flight at the end of 2019, the ship was unable to enter its intended orbit, so it had to return to Earth without reaching the station. The launch was broadcast… Continue reading Boeing CST-100 Starliner spacecraft embarks on second test flight

Russian schoolchildren will perform at the International Mathematical Olympiad without a flag

In addition, they expelled the Russian representative, Nazar Agakhanov, from the council. The decision was made following a discussion of the Olympics’ position regarding the… Continue reading Russian schoolchildren will perform at the International Mathematical Olympiad without a flag

The watch has a satellite SOS button built into it

The O-BOY company launched a watch project of the same name on Kickstarter that can send rescuers a signal for help via satellite communications. This allows them to be used even in the mountains and other places where there is no mobile connection. Satellite communications have long been used to transmit signals for help. For… Continue reading The watch has a satellite SOS button built into it

Let's go mushroom picking

What can be made from mushrooms? Soup? Vegetarian lasagna? Snack for alcoholic drinks? Not only. For a long time now, mushrooms have become an object of interest not only for culinary specialists, but also for materials scientists. The latest packaging made from mushroom analogues of biodegradable plastic surprises less and less every year. But thin… Continue reading Let's go mushroom picking

Pacemaker that adjusts to breathing helps sheep's hearts pump more blood

New Zealand researchers tested a pacemaker on sheep that modulates heart rate in response to breathing. In experiments on sheep, it increased cardiac output by 20 percent compared to a standard pacemaker. In addition, the experimental device slowed down cardiac hypertrophy, which progressed in sheep due to heart failure. Scientists spoke about their invention in… Continue reading Pacemaker that adjusts to breathing helps sheep's hearts pump more blood
