Chinese scientists turned a dove into a cyborg and used the energy of the sun to control its flight like a drone.

Scientists were able to control the bird for two hours - almost one and a half times longer than during previous experiments. Conventional commercial drones are not capable of staying in the air for that long. The controller sent signals to the pigeon's brain that stimulated the nerves. Thanks to this, the bird could be directed in any direction. The device was wirelessly connected to the base and powered by a solar panel the size of half a smartphone. In total, five pigeons participated in the testing of the technology. They followed commands with 80-90% accuracy. Guided pigeons can be used in search and rescue, reconnaissance and anti-terrorist operations.

How many burgers a week can those who want to save the planet eat.

Experts from the World Resources Institute and other organizations have prepared the State of Climate Action 2022 report. It talks about the measures that people and governments need to take to reduce the negative anthropogenic impact on the climate. 1. Meat consumption should be reduced to the equivalent of two burgers a week. This will reduce the impact of agriculture on the climate. 2. Public transport should be developed six times faster - this will reduce car emissions. 3. The process of abandoning coal must also be accelerated six times. Worst of all are the use of gas, steel production, the disappearance of mangroves, the use of cars, emissions from agriculture. To move the global economy to a low-carbon basis, an additional $460 billion will need to be allocated annually over the next ten years, experts say.

Invisible Man.

The University of Maryland has developed a sweater that turns a person invisible in the eyes of algorithms that recognize people. Artificial intelligences are trained to recognize objects, and the print on the sweater makes it difficult to do this using AML methods.

Samsung smartphones will have a "maintenance mode".

This was done for the convenience of repair - including the mode, the ability to access personal data, photographs and other details is cut off. But at the same time, service workers can easily fix the phone and check all the functions.

In Israel, they made a reactor that allows you to grow 12 times stronger cannabis.

By "strength" is meant the effect itself. According to the manufacturer, a gram of their cannabis will have 12 times more impact on the patient than naturally grown.

Engineers have created shoes that increase walking speed by 2.5 times.

A roller-like device that can be attached to almost any shoe. The blocks are equipped with an electric motor, each has 4 wheels. Moonwalkers has an intelligent control system and adapts to human movements. So, walking speed can reach 11 km/h.

Washing machine for people.

The Japanese company announced a washing machine for people: the device will clean, massage and dry the owner in 15 minutes. The task of the device is not so much in comfortable bathing as in relaxation - while the process is going on, you can relax to soothing music and enjoy beautiful pictures.

There has been a long-awaited progress in the field of earthquake prediction.

California users said on Tuesday that the Shake Alert app was able to alert them to tremors in just a couple of seconds. Not much time, but better than nothing - at least people had time to get to the shelter.

Scientists have suggested that our brain works like a quantum computer.

The capacities and electrical processes of the brain are already well understood. But powerful computing power is still a mystery. A group of scientists from Texas published a paper that analyzes the similarities between quantum computing algorithms and how the brain works. Thus, it may turn out that quantum computers have been around for a long time. In our heads.

Blood oxygen sensor test.

The journal Digital Health published a study by independent scientists who tested the effectiveness of the blood oxygen sensor on the new Apple Watch. On average, the error in comparison with professional equipment was 1.2%. Very worthy.

The benefits of video games for children.

American scientists conducted a study on more than 2,000 children and found that video games have a positive effect on children's brain development. Playing children: - Have better motor skills. - Remember information faster, easier and more accurately. - Showed higher brain activity in areas related to concentration and memory.

Elon Musk showed the giant Mechazilla in action.

The founder of Tesla and SpaceX posted a video on his Twitter page showing a giant tower with a mechanized arm called Mechazilla. It will be used to "catch" the Super Heavy launch vehicle and the Starship spacecraft on landing.

Chemists have uncovered the secret of Stradivari violins.

Italian chemists studied two violins by Antonio Stradivari and found out that the master covered them with a composition of animal proteins before varnishing. Among them was collagen. This layer filled in the smallest irregularities, influenced the resonance and improved the sound of bowed instruments. This is not the only secret of Stradivarius. A few years ago, Taiwanese chemists found a mineral preservative made from calcium, copper, aluminum, sodium, and zinc on the master's tools. Most likely, Stradivari did not just apply it to the wood - the preservative was part of the soaking of the wood.

An American built a flashlight into a prosthetic eye.

The engineer modified his prosthetic eye with a bright LED that can be used as a flashlight. When turned on, the flashlight allows you to light up a room in the dark or read books. Brian notes that the LED does not get very hot after long use, and the battery allows it to work for 20 hours in bright mode and about 10 more hours at a significantly lower brightness.

A quarter of people on Earth do not have access to clean drinking water.

Since the beginning of the 21st century, more than two billion people have gained access to clean drinking water, who did not have it before. But at the same time, a quarter of the world's population still has problems with drinking water.

New Guinness World Record in India.

In India, on the banks of the Saryu (Ghagra) river, sacred to Hindus, more than 1.5 million diya lamps were lit at the same time and set a new Guinness record. The ceremonial lighting of the lamps was held on the eve of the main Hindu holiday Diwali. The city of Ayodhya, where the new record was set, is of particular importance for the faithful Hindus, since, according to legend, the hero-god Rama, the main character of the Indian epic Ramayana, was born there.

Doctors cured cancer in mice with a radioactive gel.

Indian and American scientists created a protein gel with atoms of radioactive iodine-131 and with its help they cured pancreatic cancer in laboratory rodents - the tumors disappeared in 80% of the animals. The new method combines elements of chemotherapy and radiotherapy, but is not so dangerous for healthy tissues. The gel was injected directly into the tumor. It was destroyed by beta radiation that arose after the decay of the nuclei of unstable iodine-131. Beta radiation does not penetrate as deeply as gamma rays, so doctors managed to achieve a point effect. Due to the special structure of the protein part of the gel, it was easily excreted from the body after the procedure.

Lego for Halloween.

LEGO has assembled a gaming PC inside a large horror castle with over 20,000 building blocks ahead of Halloween. To create a computer, we used a powerful RTX 3090 graphics card, an Intel i9 12900KF processor and a customized water cooling system.

BMW cars will notify you of scratches on the body themselves.

BMW has filed a patent application for a scratch detection system that will notify the car owner of any damage to the bodywork. The technology is based on the piezoelectric effect: the control unit captures the electric charge that occurs when the film is deformed and transmits the information to the on-board system of the machine or to the cloud platform. Whether the technology will become serial is still unclear. If a scratch appears while the car is moving, it will report this with audible and visual signals. If this happens while the owner is out of the car, an alert can be sent to the smartphone.

The English police have hired a sniffer dog trained to smell the seminal fluid.

The Cheshire County Police have hired a sniffer dog trained to smell semen. Labrador named April will help investigate rape and other sexual crimes. A dog can smell 0.016 milliliters of seminal fluid even if it was left at the crime scene years ago. April's training lasted six weeks. The dog has already started his first case - he was called to the scene of another crime 36 hours after being hired.
