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

An engineer assembled a four-legged exoskeleton for a snake

American blogger and amateur engineer Allen Pan has developed an exoskeleton for snakes. It consists of four robotic legs and a pipe containing a snake. Exoskeletons are devices that allow you to expand and enhance the movements of the body or replenish lost functions. These are typically full-body suits that allow you to lift heavy… Continue reading An engineer assembled a four-legged exoskeleton for a snake

The drone opened the cabinet and turned the valve

Swiss engineers have taught the drone to manipulate objects, for example, open cabinets and turn valves. Article published in IEEE Robotics and Automation Letters. Interacting with objects is one of the typical tasks for robots. In drones, due to the fact that they fly and do not drive or walk on the floor, this task… Continue reading The drone opened the cabinet and turned the valve

Wall robots turned into interactive shelves

American engineers have proposed using wall-mounted robots as an interactive storage system. They can move along the wall, bring the necessary things to a person or take them back. A video demonstrating the prototype's operation was published on YouTube. Most robots for helping around the house are similar: they are devices that move across the… Continue reading Wall robots turned into interactive shelves

Stingrays can make sounds. They clicked on the divers

Zoologists have demonstrated for the first time that wild stingrays can make sounds. The researchers made this conclusion after analyzing video recordings of stingrays Urogymnus granulatus And Pastinachus ater they clicked warningly when divers approached them. How noted in an article for a magazine Ecology Stingrays probably use clicks to scare away predators. At the… Continue reading Stingrays can make sounds. They clicked on the divers

Physicists have created a split neutron interferometer

European physicists have built the world's first separated neutron interferometer. In their experiment, they worked with a symmetrical circuit in which only the analyzer is movable. Thanks to a high-precision positioning system and temperature control, they were able to obtain a contrast interferogram. In the future, their developments will help create an skew-symmetric neutron interferometer,… Continue reading Physicists have created a split neutron interferometer

The Chinese showed tests of an air taxi with a car steering wheel

The Chinese company HT Aero showed the flight of an air taxi controlled using a control stick and a car steering wheel. By 2024, the company plans to release a car that can produce folding propellers and take off. In recent years, dozens of companies around the world have been actively developing air taxis –… Continue reading The Chinese showed tests of an air taxi with a car steering wheel

The Chinese showed tests of a city autopilot for a production car

The Chinese company XPeng showed tests of an advanced driver assistance system on the streets of Guangzhou. The car drove 26 kilometers in fully autonomous mode, although an engineer was driving. Autopilot was tested on a production XPeng P5 electric car, but so far it is a beta version and not available to ordinary drivers.… Continue reading The Chinese showed tests of a city autopilot for a production car

Due to climate change, wild dogs have delayed breeding by 22 days in 30 years.

Due to climate change, wild dogs found themselves in a phenological trap. Over the past 30 years, they have moved their breeding times forward by 22 days to produce offspring during the coolest weather, when hunting is most comfortable. However, as a result, the ninety-day period the pups spend in the burrow now occurs during… Continue reading Due to climate change, wild dogs have delayed breeding by 22 days in 30 years.

KAMAZ has developed an unmanned dump truck without a cabin

The KAMAZ company presented a fully unmanned hybrid dump truck “Jupiter-30”, which does not have a driver’s cabin. It uses a hybrid powertrain with an internal combustion engine generating power for two electric motors. After setting up and testing at the company’s test site, the prototype will be tested in a coal mine in Kuzbass.… Continue reading KAMAZ has developed an unmanned dump truck without a cabin
