Ornithologists have described a new bird species from the subantarctic islands

Ornithologists have described a new species of bird that lives on the Diego Ramirez Islands south of South America. It is called the subantarctic rayadito. In the past, the local population was thought to be the spiny-tailed rayadito, which is widespread in Chile and Argentina. However, the analysis showed that individuals from the Diego Ramirez… Continue reading Ornithologists have described a new bird species from the subantarctic islands

Ingenuity survived the Martian winter

The Martian drone Ingenuity made its first full flight after two months of inactivity, thereby confirming that it successfully survived the coldest part of the Martian winter. In the near future, the drone will receive a software update and will go to explore the delta of the ancient river in the Jezero crater. reported on… Continue reading Ingenuity survived the Martian winter

Airbus pseudosatellite crashed on day 64 of flight

An unmanned aircraft with solar panels, Airbus Zephyr 8, crashed after 64 days of flight, reports Simple Flying. Airbus confirmed the end of the flight without disclosing the reason. The plane lacked less than a day to break the flight duration record set in 1959. However, he broke his own record for the duration of… Continue reading Airbus pseudosatellite crashed on day 64 of flight

Argo AI tested self-driving cars with a bird model on a quadcopter

Argo AI showed off one of the challenges its self-driving cars face during testing at the proving ground. To test how cars react to diving and low-flying birds, engineers decided to hang a bird model on a quadcopter and fly it over the test site at car level. The best way to train a self-driving… Continue reading Argo AI tested self-driving cars with a bird model on a quadcopter

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

One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

Astronomers have summed up their observations of the occultation of the background star by the Trojan asteroid Jupiter Polymela, which was chosen as one of the targets for the interplanetary station Lucy. Their results confirmed the discovery of a satellite with a diameter of 5 kilometers around the asteroid, which is located at a distance… Continue reading One of the Trojans for the Lucy station turned out to be an asteroid with a satellite

Jupiter has limited the parameters of dark matter

Theoretical physicists have proposed a new method for constraining the parameters of dark matter based on data obtained by the orbiting Galileo spacecraft and the Juno station. The researchers calculated the flux of relativistic charged particles produced as a result of the annihilation of dark matter particles and compared the resulting theoretical value with the… Continue reading Jupiter has limited the parameters of dark matter

Physicists have implemented optical stochastic cooling of particle beams

American physicists reported that they were the first to realize optical stochastic cooling of beams of charged particles. This type of cooling consists of damping pulse fluctuations through a feedback system. In the new work, this communication occurred at optical frequencies, which is necessary to increase the efficiency and cooling rate of accelerators and synchrotrons.… Continue reading Physicists have implemented optical stochastic cooling of particle beams

Solar power plant mirrors roasted chili peppers

An American engineer used light collected by the heliostats of an experimental solar power plant to roast green chilies and compared the result with the product obtained by traditional gas burner roasting. A blind tasting showed that the new method resulted in better flavor and more uniform processing of the peppers. The developed approach can… Continue reading Solar power plant mirrors roasted chili peppers

The French presented a manned drone with turbojet engines

The French company Zapata presented a high-speed manned drone with ten turbojet engines. She also showed a recording of flight tests, during which the drone not only flew in a straight line, but also turned over in a controlled manner. The drone's estimated maximum speed is 250 kilometers per hour, and its payload capacity is… Continue reading The French presented a manned drone with turbojet engines
