The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

Chemists have found ideal conditions for the hydrogen borrowing reaction

Chemists from Russia studied the hydrogen borrowing reaction necessary for the formation of carbon-nitrogen bonds. They found that it often does not require a catalyst at all, and also developed recommendations for successfully carrying out the reaction in the laboratory. The study was published in the journal Journal of Catalysis. Organic compounds containing an NH… Continue reading Chemists have found ideal conditions for the hydrogen borrowing reaction

The algorithm determined the mouse's pain level based on its muzzle expression

American scientists have developed a cloud platform that can assess the severity of pain in black laboratory mice. She analyzes the expression of the animal's face – the position of its nose, ears, whiskers and the degree of squinting of the eyes. Previously, researchers coped with this task manually, but, as the results show, the… Continue reading The algorithm determined the mouse's pain level based on its muzzle expression

Ingenuity survived the Martian winter

The Martian drone Ingenuity made its first full flight after two months of inactivity, thereby confirming that it successfully survived the coldest part of the Martian winter. In the near future, the drone will receive a software update and will go to explore the delta of the ancient river in the Jezero crater. reported on… Continue reading Ingenuity survived the Martian winter

Starlink satellites will be able to connect directly to regular smartphones

The new generation of Starlink satellites will allow anyone with a smartphone to connect to the mobile network and the Internet, even from places where there is no terrestrial coverage. The connection speed will be from two to four megabits per second. This was announced by SpaceX CEO Elon Musk and T-Mobile President Mike Sievert.… Continue reading Starlink satellites will be able to connect directly to regular smartphones

Chinese scientists have deprived mice of a chromosome. And then another one

Chinese scientists have tested a new method of genome engineering: they have learned to stitch mouse chromosomes together. It turned out that if the chromosomes are not very large, then it is easy to glue them together and get a mouse with an odd number of chromosomes. Such animals can grow up healthy and fertile… Continue reading Chinese scientists have deprived mice of a chromosome. And then another one

Coordination polymers caused water to absorb oxygen

Chemists from the USA have developed several microporous materials capable of forming stable colloidal solutions in water and in this form absorbing carbon dioxide and oxygen. To do this, the scientists used compounds with a hydrophilic outer surface and a hydrophobic pore surface. This made it possible to increase the ability of water to dissolve… Continue reading Coordination polymers caused water to absorb oxygen

Perseverance discovered volcanic rocks instead of sedimentary ones in Jezero Crater

The Perseverance rover discovered volcanic rocks in the Jezero Crater. This contradicts the expectations of scientists who expected to see sedimentary deposits. Their absence may indicate that the lake at this place disappeared too quickly, and sedimentary rocks did not have time to form. Two articles (1 and 2) devoted to the results of Perseverance’s… Continue reading Perseverance discovered volcanic rocks instead of sedimentary ones in Jezero Crater

Butyrate saved mice from peanut allergies

Butyrate, which is produced by the intestinal bacteria Clostridium, may help people with severe peanut allergies. This was discovered by scientists who introduced polymer micelles with butyrate into the intestines of mice and relieved them of allergies. The authors believe that such micelles can also help with reactions to other food proteins. A preprint of… Continue reading Butyrate saved mice from peanut allergies

Microrobots made from human cells launched the regeneration of nervous tissue in vitro

American researchers have created spheroid mobile microrobots from unmodified living human cells. In the experiment in vitro with their help, it was possible to initiate rapid healing of nervous tissue. The work is available as a preprint on bioRxiv. The idea of ​​using living cells to create biorobots is very attractive, since such structural components… Continue reading Microrobots made from human cells launched the regeneration of nervous tissue in vitro
