English scientists have taught drones to Leeds
English scientists have taught drones to fly in the dark
Have you ever wondered how mosquitoes fly in the dark? And why don't they stumble upon trees and walls? After all, the organs of vision or echolocation, like bats, these insects of the diptera do not use. Researchers at the University of Leeds in the UK understood the mechanism of “night vision” of mosquitoes, calling it an “aerodynamic image,” Science writes.
Insects in the dark use streams of air created by the flapping of their own wings. The jets of air change pressure and speed when an obstacle appears in front, and the mosquito feels these changes thanks to Johnston's organ - a set of receptors at the base of the “antennas” on the head. The maximum distance that a mosquito can “feel” is about 20 lengths of its wings. It was previously believed that this spatial gap is smaller.
Scientists have created a mechanical analog of the mechanism - a set of probes and sensors that record pressure drops. The development is inexpensive and reliable, it can be used on drones. The tests of the new system fixed to the drone were successful, the aircraft detected obstacles in the dark and circled them.

Residents of Britain reported about huge black cats who attack sheep
Photographs of a large black cat hiding in the bushes were published by residents of the village of Tedburn St. Mary. In addition, traces of paws were observed, presumably belonging to the same predator, next to the remains of a deer. The forest near the village is now rarely visited by residents due to the regime of self-isolation and this, as local residents suggest, could give courage to large predators.
Dr. Terry Moore, a specialist in large predators of the feline family, said that reports of large cats, presumably cougars and panthers, had been received several times before from Hertfordshire, a four-hour drive from Devon.
Among locals there is an opinion that the huge cats, which they call "Beasts of Bodmin" and "Beasts of Dartmoor", have been living in the swamps of Devon and Cornwall for more than a decade. In July 2019, the owner of the zoo in Dartmoor said that he personally observed three cougars freely walking in the wild, which should have been transferred to the zoo at least three decades ago.
It is believed that panther and cougar could be let out by circus artist Mary Chipperfield after the closure of her zoo in Plymouth in 1978. Since 2000, more than 200 reports of large cats walking through swamps have been recorded in Devon and Cornwall.
