Scientists have not found any connection between people's playing time and their well-being.

Oxford conducted an experiment using 39,000 gamers. They all played varying amounts of hours per week. And according to scientists, there is no connection at all between how well people feel and the amount of time people spend playing games. Well-being meant not only health but also emotional state. According to the results of the study, it was announced that games begin to affect the psyche and health only when a person plays 10 or more hours every day for a long time.

Day of ecological debt.

Thursday, July 28th is Ecological Debt Day, by which point humans have consumed all the resources the Earth can recreate in a year. Further, humanity will take them from nature on credit. The earlier Eco-Debt Day comes, the more debt grows. The debt burden of different countries is unevenly distributed. If everyone was consuming resources like Americans, Eco-Debt Day would be March 13th.

In Singapore, they created a wound-healing plaster made of frog skin.

The frog collagen patch creates a porous layer in which leukocytes and healing substances stick together. It accelerates the healing of wounds, as it also serves as a barrier that retains moisture. Collagen also works as a scaffold around which nearby skin cells can gather. The patch itself breaks down over time. Collagen from frog skin is more biocompatible with humans than structural proteins from other animals.

Scientists will look for illuminated cities on other planets.

The journal Acta Astronautica published a study stating that the current level of progress is sufficient to try to find signs of street lighting on other planets. These signatures are easy to separate from natural sources. And according to them, this is a very simple and original way to search for extraterrestrial civilizations. After all, cities in the evenings glow like light bulbs.

They learned how to extract hydrogen directly from tap water without any electrolysis.

Scientists from Spain have demonstrated a working prototype of a device that could be the key to cheap fuel. After all, electrolysis, which usually produces hydrogen, requires a lot of electricity.

The trailer for The Samaritan starring Sylvester Stallone has been released.

According to the plot, a local tramp is recognized as a superhero who has been hiding for 25 years. But now he will have to return to his duties again. It will premiere on August 26 on Prime Video.

In Britain, found traces of the first jellyfish of the Earth.

In Charnwood Forest in Leicestershire, paleontologists have found body prints of the oldest jellyfish on Earth. She lived about 560 million years ago. This means that the first animals from this group appeared on the planet 20 million years earlier than is commonly believed. A. attenboroughii looks like a cross between a jellyfish and a coral. Her body is a standard goblet shape, but it is divided into several polyps. Scientists believe that A. attenboroughii was imprinted in the rock after it suffocated in sediment and ash flowing down the slope of an ancient underwater volcano.

In New Zealand, a new art object is being sold for 10 thousand dollars - a cheeseburger cucumber glued to the ceiling.

This is the work of Australian artist Matthew Griffin called Pickle ("Pickle"). The Pickle buyer will receive instructions to recreate the work in their own space. Additionally, you will have to purchase a cheeseburger for $4.44. Admirers and critics of contemporary art appreciate Pickle in different ways. The first consider the work brilliant, the second - idiotic. "When I was a teenager, the police kicked me out of McDonald's for this, and now it's art," said one reviewer.

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.
