Chinese scientists have taught cows to produce human milk.

According to foreign media, scientists from China conducted an experiment by introducing proteins inherent in the human body into the embryos of Goldstein cows. The scientists then placed these fetuses in surrogate cows. In the future, it can be used for artificial feeding of infants.

In California, they made the largest camera in the world with a resolution of 3200 MP.

At the National Accelerator Laboratory SLAC (Stanford Linear Accelerator Center - Stanford Linear Accelerator Center) in Menlo Park, California, the construction of the largest chamber in the world is almost completed. Its resolution is 3.2 GPU, or 3200 MP. To make it all work, a lens with a diameter of 1.57 meters is used: The minimum shutter speed is 15 seconds. This length is due to the size of the matrix, which must be closed when creating a snapshot. In fact, these are 189 separate CCD matrices, each of which has a resolution of 16 megapixels. All matrices are combined according to the formula 3 × 3, that is, nine pieces in each square block, of which there are 21 pieces.

Artificial intelligence has broken a 50-year-old record in mathematics.

Multiplication of two 4x4 matrices usually consists of 64 steps. Volker Strassen in 1969 came up with an algorithm that reduces the number of steps to 49. The AlphaTensor neural network from DeepMind found a way to reduce the number of steps to 47. And in 5x5 matrix multiplication, the neural network reduced the number of steps from 98 to 95. Considering that this is one of the most popular operations in modern computers, video cards and other devices will soon become a little faster.

Women are better than men at crossword puzzles and playing scrabble.

Indicators of verbal fluency and verbal episodic memory are higher in women than in men. This means that they quickly recall and select words, especially those starting with a particular letter. Therefore, women are better at solving crossword puzzles and playing scrabble. These conclusions were reached by Norwegian scientists after a meta-analysis of 168 studies over the past 50 years, in which a total of 350,000 people participated.

Queen released an unreleased single in 1989.

The musicians of the Queen group released a single with the real vocals of Freddie Mercury - Face It Alone ("Face it alone"). The song was recorded while working on the 1989 album The Miracle. After 30 years, it was restored in the studio with the help of modern technology. The composition was rediscovered by the band's archivists, who studied old recordings while working on the reissue of The Miracle. The musicians called Face It Alone "a little gem from Freddie".

Endangered penguins get rid of their firstborn for the survival of the species.

Scientists have figured out why endangered two-egg-laying crested penguins drop the first and only hatch the second, which emerges about five days later. It turned out to be a strategy for the survival of the species. The first egg is formed in the body of the female when she is still heading to the nesting sites by sea, so it is small. The second is already on dry land. It is larger, which means that the chick hatched from it is more likely to survive.

Found a common ancestor of fungi and animals.

The journal Nature published a study deciphering the genomes of fungi and animals back to ancient times. It was revealed that the common ancestor lived about a billion years ago and was a single cell. It's funny that thanks to this study, it was possible to find modern unicellular organisms that are very close to both fungi and animals.

Scene from "Space Odyssey"

Astronaut Samantha Cristoforetti who is currently working on the ISS, repeated a scene from Stanley Kubrick's A Space Odyssey. In the original scene, a stewardess in Velcro shoes goes around the ship 180 degrees and stands on the "ceiling". Samantha repeated the trick also with Velcro, but walking is rather slow.

NASA has proposed using space technology to charge cars.

The James Webb Telescope and other spacecraft are equipped with unique cooling technologies that can cool devices down to near absolute zero. This technology NASA proposes to adopt charging cables. If they are cold enough, the amperage can be increased significantly. And charge a full battery in five minutes.

For the first time in history, a humanoid robot spoke at a hearing in the British Parliament.

Actually, this is she - Aida (Ai Da). Appears like a woman and mostly draws, but is also able to communicate with her voice. She was invited to a hearing in the House of Lords. The topic is the impact of digital technologies on creativity. In particular, the question was raised that people are losing their jobs due to the fact that they are being forced out of the market by robots. Here the creator of Aida, Aidan Meller, had to intervene, who said that one should not treat it like that. Robots are an opportunity, not a threat. In the hall, they asked Aida how she creates her paintings. To which I received this answer: I paint with the help of cameras in the eyes, AI algorithms and signals transmitted to the hand, which ultimately leads to the birth of visually attractive images on the canvas.

Lab-grown brain cells taught to play ping-pong.

And at the same time they found out how many cells are required for this. Startup DishBrain, engaged in the study of neural networks and the brain, found out the exact number. It takes 800,000 brain cells to play tennis. This is the first study of its kind in history - now, DishBrain will grow more brain cells to move on to serious tasks.

A Japanese professor has created a screen that you can lick to taste movie food.

Behind the screen is a complex technology of a dozen jars of flavors, the combination of which allows you to recreate the taste of almost any product.

People who grew up on the coast are mentally healthier than the rest.

Hours and days spent as a child in the blue zones - near the shores of lakes, rivers, seas - have a positive effect on mental health and well-being in adulthood. Such people often return to the coast and appreciate nature more. These conclusions were reached by a team of scientists from Europe and the United States during a study involving 15,000 people from 18 countries. Volunteers filled out questionnaires in which they indicated how often they spent time in the blue zones as children, and also assessed the state of their psyche. According to scientists, the results showed that blue zones for the spiritual, intellectual and physical development of children are just as necessary as green ones: squares, parks and forests.

For half a century, wild animals in the world have become 69% less.

Since 1970, the world population of wild animals has decreased by 69%. Blame it on deforestation, ocean pollution and climate change. In general, wild animals on the planet become 2.5% less every year. Those in Latin America and the Caribbean have been hardest hit. There, over half a century, populations have declined by 94%. For example, pink river dolphins in the Brazilian Amazon have decreased by 65%. Their numbers dropped sharply between 1994 and 2016. According to WWF experts, nature is in a desperate situation and is being destroyed. The Fund encourages developed countries to spend more on programs to preserve the planet's biodiversity.

The Briton started home 300 tarantulas on the advice of a psychotherapist.

Aaron Phoenix from Bristol has 300 tarantulas in his home after being encouraged by a therapist to take up a hobby to better deal with his bipolar disorder. Phoenix decided that collecting spiders would be great for him. He gets new pets in the mail every week. Delivery couriers have already nicknamed 35-year-old Aaron Spiderman. The pride of the Phoenix collection is a female Mexican fire-knee tarantula. It cost Aaron £160. The spider, along with her brothers, occupies all the free space in the master's bedroom.

Acceleration of the electric car to 100 km / h in 1.416 seconds.

A team of students from the University of Stuttgart called the GreenTeam accelerated an electric car to 100 km / h in 1.416 seconds and set a Guinness record. The body is made of lightweight and durable carbon fiber, and the electric power plant delivers 180 kW of power to the four-wheel drive. The whole structure weighs only 145 kg. The pilot must be prepared, because during acceleration, the peak load reaches 2.5 g, which is higher than in Formula 1 cars and is comparable to the loads of astronauts at launch. The previous record for electric vehicles was 1.513 seconds and was set by the Swiss team AMZ Racing.

Neuroscientists have explained why people don't laugh when they tickle themselves.

German neuroscientists have tried to figure out why people don't laugh when they tickle themselves. After experimenting with 12 volunteers, they hypothesized that the brain temporarily blocks touch sensitivity when a person touches their own body. Otherwise, we'd be giggling while putting on socks or scratching our armpits. People with delusions of influence do not have this feature. They are able to laugh, even tickling themselves.
