The fourth patient in the world has completely recovered from HIV infection.

This is a 66-year-old man who became ill back in the 1980s. He was helped by a bone marrow transplant - it was done to treat leukemia. The donor had a rare DNA mutation that makes the body immune to the virus. He is called the "patient from the city of hope" - in honor of the Californian Duarte, where the man was treated.

Biologists are considering developing "legal psychedelics" to treat disease.

Studies have proven that drugs that were banned decades ago can help with addictions, mental and other disorders. So far, no company has brought a psychedelic drug to market. At the same time, the question is whether the “mystical experience” that appears as a result of the use of hallucinogens is so important in itself. Some researchers believe that it is through it that patients can resist the root causes of various mental illnesses.

Scientists have discovered a gene responsible for the growth of muscle mass.

After the analysis of skeletal muscles, it became known that during training, the C18ORF25 gene is most often activated - it is responsible for the muscles. An animal experiment has shown that their muscles become stronger when C18ORF25 activity is increased.

Physicists have learned how to direct lightning with a laser.

To do this, they illuminated the space above the Sentis tower, located in the mountains of Switzerland, for two months during a thunderstorm. Of the 16 lightning bolts that hit the tower during the observation period, four were stimulated by a laser. Recent estimates show that, on average, lightning kills more than 4,000 people a year and costs the economy billions of dollars.

A reforestation firm accidentally burned 14,000 hectares of forest.

Reforestation company Land Life, which plants trees to offset carbon emissions, accidentally burned 14,000 hectares of forest in Zaragoza in northern Spain. The fire broke out due to a spark from one of the excavators. First, small plants broke out, and then the fire spread to the trees. Due to the fire, five neighboring cities and several nursing homes had to be evacuated. In total, about 2,000 people had to be rescued.

Scientists have found places on the moon with very comfortable temperatures.

In peculiar dips, which are most likely lava tubes, the Lunar Reconnaissance Orbiter probe recorded quite comfortable +17 degrees. Moreover, the temperature is quite stable - you can live.

The drone from Amazon will not leave a chance for robbers.

The company has its own expensive Ring security system, but the real deal is a small drone that will chase robbers if it detects a break-in. The drone is completely autonomous and after the frightened thief escapes, it will return to its original position, continuing to protect your home.

Ant colonies behave like neural networks when making decisions.

When each individual ant in a group feels hot underneath, it holds on as usual until the entire colony suddenly changes course. “They run out as one,” the scientists say. "It's almost as if they have a large collective intelligence." The data obtained during the experiment indicate that the ants combine sensory information with the parameters of their entire group. So they make one decision for all. This process is similar to neural computing, leading to decision making in the same way.

Drinking water is just as pleasurable for the brain as sex and delicious food.

A team of scientists from the US found that when drinking water, part of the brain releases dopamine, as is the case with such pleasurable activities as sex and eating delicious food. The researchers were able to trace this process during experiments on mice.

Scientists from China have found that the trajectory of tail wagging in dogs depends on their emotional state.

In the process of conducting tests, it was possible to find out that the dog wags its tail to the right more often if a familiar person is in front of him, if he feels comfortable. While wagging his tail to the left makes it clear that he is uncomfortable or there is a stranger in front of him.

Chinese scientists have created a laser that can write directly in the air.

Scientists at the Hongtuo Ultrafast Laser Laboratory in Wuhan have created a laser pen that can draw patterns in the air. It uses ultrashort laser pulses to strip electrons from air particles and turn them into light-emitting plasma or ionized gas. The image obtained with the help of such a laser is visible from all sides. The creators of the laser say that it can be used in high-precision manufacturing, medicine and quantum computing.

The James Webb telescope has found the oldest galaxy that existed 13.5 billion years ago.

We are most likely seeing GLASS-z13 as it was just 300 million years after the Big Bang. This is as much as 100 million years less than the previous record holder. The galaxy has a mass of a billion suns, which is potentially very surprising given how soon after the Big Bang it formed.

The UK's largest radio telescope has been converted into a backdrop for a light show.

Lovell's giant radio telescope will take center stage at the Bluedot festival. On the surface of its dish will broadcast images from the James Webb Space Telescope, NASA Blue Marble Next Generation satellites, photographs of the near and far sides of the Moon, as well as the surface of the Sun. The soundtrack for the show will be recordings from space, including the sonification (representation of information in audio format) of a scan of the Milky Way galaxy made by a radio telescope.

Saudi Arabia has unveiled plans to build a $1 trillion mirror glass skyscraper 120 km long.

The "Mirror Line" will become part of a desert city called Neom. The Saudi prince has said he wants his country to build an iconic and timeless building project similar to the Egyptian pyramids. It is assumed that the building will not have roads and cars - only footpaths. At least in the ground part of the city. There will be another level underground - service infrastructure and transport will be placed there. It is planned to use only renewable energy.

Elephants can communicate with their feet

Special nerve endings on the legs of elephants are able to capture various types of vibrations emitted by their relatives. True, they also hear with their ears, but poorly.

Serotonin, which is responsible for happiness, can be toxic.

It causes severe pain on contact with the skin and is the main ingredient in wasp venom.

Excessive self-confidence reinforces anti-scientific views.

A team of scientists from the United States found that overconfident people are more likely to trust anti-scientific views than those who are used to self-doubt. “Overconfidence interferes with learning,” says study lead author Nicholas Light.

Facts about Mars.

The Martian day is 24 hours 39 minutes, which is very close to Earth. And we could use an extra 39 minutes! Martian sunrises and sunsets are the exact opposite of earthly ones. Because of the dust scattered in the atmosphere of the planet, they are painted in blue tones. Mars currently has no global magnetic field. However, there are magnetized areas in its crust, indicating that the planet possessed it in the distant past.

In the Netherlands, they created a prototype carbon dioxide-absorbing electric car.

As planned, the invention will be able to absorb more CO2 than it will produce during its life cycle. The creators developed the monocoque and body panels using additive technologies to reduce material waste and produce as little carbon dioxide as possible.

Miracle mattress.

Texas has developed a mattress that should make users feel sleepy thanks to properly positioned cooling and heating elements. In particular, the central areas of the body are cooled, while the arms, legs and neck are heated. Two versions of the mattress (one with water and one with air) were tested on 11 volunteers. Participants were forced to go to bed two hours earlier than usual, and on some nights the cooling and heating functions were turned on, while on others they were not. The scientists found that cooling and warming up caused the subjects to fall asleep about 58% faster.
