The sidewalks of the future will turn steps into electrical energy.

As pedestrians walk through the Pavegen system, the weight from their footsteps presses on electromagnetic generators, producing 2 to 4 joules of off-grid electrical energy per step. Bluetooth low energy beacons connect to smartphone apps. It can also interact with building management systems. It is a pure form of energy that is lost when we walk on a plain concrete pavement. Pavegen is created from triangular composite tiles that are supported by electromagnetic generators.

Massive Attack released the album Mezzanine in 1998.

Its peculiarity was that it was recorded on synthetic DNA, which was later compressed into molecules, and then sold in aerosol cans. One such bottle contained about a million copies of the album.

The population of the Earth.

Today, November 15, the world's population officially exceeded 8 billion people, according to the UN. The organization predicts that the world's population could grow to around 8.5 billion in 2030 and to 9.7 billion in 2050. It will peak at about 10.4 billion people in the 2080s and remain at that level until 2100. More than half of the projected global population growth by 2050 will be concentrated in eight countries: Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, Philippines and the United Republic of Tanzania.

Scientists have taught artificial intelligence to “sleep”.

The Czech Republic proposed a biological approach to the operation of neural networks. After training, they are offered to be closed to new data and sent to a special process of “sending the received information to deep memory”. Just like people do when they sleep.

Scientists have discovered that rats move their heads to the beat of Mozart.

Scientists from Japan have proven that fluffy cats have a sense of rhythm, and this is not an accident, but a scientifically proven fact.

Uganda will print human organs in space.

This is no joke - the country has a well-developed market for 3D printers. And in space they are no strangers - on November 7, Uganda launched its first satellite, PearlAfricaSat-1.

Drunken elephants.

In India, 24 elephants got drunk and fell asleep in the forest. The inhabitants of the local village wanted to make a liquor from mahua flowers, and for this they left pots with fermented liquid in the jungle. Elephants got to them and devoured everything. The animals got so drunk that they could not be awakened for several hours.

А bracelet has been developed to combat alcoholism.

Hento Touch simulates pleasant strokes that cause the release of positive hormones. According to the researchers, this reduces stress levels. And thus, helps a person to refrain from drinking.

Parkinson's disease and Covid have learned to recognize by voice.

The IEEE Access journal published the results of tests of a neural network that recognizes Parkinson's disease by a person's voice with almost 100% accuracy. And Covid - with an accuracy of 94%. Moreover, an ordinary smartphone was used as a microphone.

Disadvantage of distance education.

Beautiful students stopped getting high grades after switching to distance learning. A large number of studies show that appearance affects a person's success. But a Swedish researcher noticed that this does not work with online learning. Attractive female students experienced a decline in distance learning grades, while this did not affect male students.

Unusual work of a digital artist.

Digital artist Idreley Lely Dian showed what famous cartoon characters would look like if they were real people. To create his work, the author uses Photoshop and photo editing applications that use neural networks: FaceApp, Gradient and Remini.

XPeng showed the first tests of its AeroHT X3 flying car.

The car looks awkward as it is an early prototype. Soon they promise to make folding screws. Each of the four sections has two propellers with their own electric motors. Such a solution will allow maintaining stability in the air in the event of failure of individual engines. Plans for the timing of release and the estimated cost of the commercial version are also not disclosed.

The skull of the famous Tyrannosaurus Maximus will be sold at auction.

Auction house Sotheby's will put up for auction in New York in December the skull of Tyrannosaurus Maximus - one of the best and most completely preserved on Earth. The 76 million year old fossil is valued at $15-20 million. At the same time, there are two punctures on the skull. Most likely, Maximus fought fiercely with another tyrannosaurus. Perhaps it was in this fight that he died. Maximus is not the first Hell Creek Tyrannosaurus to be auctioned. In 1997, an almost complete skeleton of his relative named Sue was sold for 8.36 million dollars. In 2020, the remains of Stan's Tyrannosaurus Rex went under the hammer for $31.8 million. And on November 30 of this year, a 1.4-ton Shen skeleton will be sold in Hong Kong.

In China, they introduced a fighting robot dog with a huge gun.

At AirShow China 2022, a robotic dog with an automatic gun on its back was spotted. It is stated that the robot carries a gun weighing 14 kg. The dog is controlled by an app on a military tablet. There are also built-in cameras with a 360-degree viewing angle. For what purposes this robot will be used is not yet clear. Most likely, this is just a demonstration of technological development within the framework of the exhibition.

The hottest bird

Found the hottest bird on the planet. A red-billed weaver living in Africa can cope with a body temperature of up to 48 degrees without any side effects.

Sharks get bigger and angrier after meeting people.

From frequent contact with people, tiger sharks become larger and more aggressive. These conclusions were reached by Brazilian and American scientists who observed fish on the tourist Tiger Beach in the Bahamas. The sea in this place is shallow and clean, so sharks often swim there. Tour operators specially feed them to make diving customers more fun. It turned out that the sharks most often appearing on Tiger Beach were larger than other sharks, their hormone levels were 3-16 times higher, and their blood contained more nutrients. That is, mass tourism is likely to have a positive effect on the health of sharks. At the same time, the aggressiveness of fish may be due to competition for food. Most often, adult females swam up to people, many of them were pregnant. Juveniles stayed away from Tiger Beach.

A supercomputer has predicted the end of the world by 2050.

Supercomputer World One predicted the collapse of human civilization as we know it in the 2040s and 50s. Virtually no measures to save people will no longer help. The machine took into account many factors: birth rates, environmental pollution, natural resource reserves and other indicators. The algorithm has already predicted that in 2020 the planet will enter a critical phase of habitual existence.

The world's oldest letter inscription turned out to be a conspiracy against lice.

Israeli scientists have deciphered the oldest alphabetic inscription - it was made in Canaanite on an ivory comb. The age of the artifact is about 3.7 thousand years. The size of the scallop is 3.5 by 2.5 centimeters. The width of the engraved tiny letters is 1-3 millimeters. There are 17 of them, they form seven words. "Let this fang rip the lice out of the hair and beard," is written on the comb.

Dim winter lighting impairs cognition by reducing the connectivity of neurons in the brain.

These conclusions were reached by scientists from the University of Michigan in the course of experiments with grass mice. They, like humans, are awake during the day and sleep at night.

Scientists have found a "tumbler" for immersion in hibernation in humans.

They found a group of neurons in the hypothalamus, presumably responsible for putting a person into a state of hibernation - hibernation, during which physiological processes in the body slow down. The results of the study will be useful for planning long-term space flights.
