However, when testing the team was waiting for a nontrivial problem: the cube itself, due to the mechanical design, did not have enough time to rearrange itself in dexterous robotic hands. Because of this, the puzzle jammed during the first test. A small modification solved the problem.
This is not the first time robots have been tasked with assembling a Rubik’s cube. For example, fifteen years ago they did it in 67 seconds, and in 2016 the time was already less than a second.

3 The findings show that Neanderthals had a sense of style: they used jewelry and even makeup. This shows their ability to think symbolically.
4. they were empathic and compassionate, caring for their fellow humans even when they were no longer active members of the community due to illness, injury or age.
5. There are theories about the possibility of restoring Neanderthals by DNA. At least, the dynamics of genetic technology allow for such a scenario, but this prospect faces ethical and legal problems and does not yet have broad support.

A detailed study of the cellular structure of the fossil was made possible thanks, among other things, to research methods using ultraviolet radiation.

As a result, the experts were able to invent a mixture called MEDY. Its composition included ethylene glycol, Y27632, methyl cellulose and dimethyl sulfoxide. As demonstrated by the tests, thanks to this mixture, the tissue thawed without damage, and neurons were able to send signals in the usual mode.
According to the researchers, by freezing organoids, it will be possible to preserve more tissue to test new drugs and treatments. However, experts doubt that thanks to MEDY it will be possible to preserve a complete organ in freezing.

As the experts found out, the reproduction of viruses occurred with the participation of red algae. This connection appeared 1.5 billion years ago. Back then, viruses evolved by borrowing genes from each other to adapt to hot weather and poisonous substances like arsenic.
The deoxyribonucleic acid contained 921 candidate genomes, likely passed between hosts. The experiment found confirmation of the presence of viruses in all places where there is cellular life. As experts have established, they arose on Earth at the same time as cellular organisms and contributed to the movement of genes.

Why was it such a strange color?
The color of a meteor depends on its chemical composition and how fast it passes through the atmosphere. For example, yellow meteors are usually formed by the combustion of sodium-rich motheoroid, orange-yellow indicates the presence of iron, blue-green indicates magnesium, purple indicates calcium, and red meteors are formed by the heating of nitrogen and oxygen in the atmosphere.

An unusual structure near the comet’s nucleus can be seen in the photo – it is its tail, which broke off due to a powerful solar wind shock wave.
One of the first recorded examples of such a phenomenon occurred in April 2007, when NASA’s STEREO-A spacecraft observed how a coronal mass ejection ripped off the tail of Comet Encke.

The first prototype of SuperLimbs was created a decade ago, but scientists are constantly refining it, and in the new version they have developed a special algorithm to help astronauts in lifting, which in the course of experiments has demonstrated its effectiveness. The engineers from MIT have plans to produce a full-fledged wearable version of the robot.

As noted in the agency, as of May 7, thrust BepiColombo managed to increase to 90% of the previous. However, ESA emphasized that the full recovery of thrust is still not achieved. Experts specified that the reasons for the failure to this day remain unknown.
Engineers are still trying to resolve the situation and find out what causes it. However, if they fail, the station should still be able to cope with the fourth gravity maneuver near Mercury, scheduled for September this year.

With a high probability it is. But since there is no way to track the history of spots on the opposite side, the newly reappeared object has been assigned a new number 3697, according to the international classification.
The active region will move across the Sun over the next 14 days. As it approaches the Sun-Earth line, we should prepare for new magnetic storms and auroras.
