The first effective artificial sun in the US is to be ready in 5 years

Scientists from the Massachusetts Institute of Technology and Commonwealth Fusion Systems said they are in the process of building an experimental artificial sun called SPARC. Their reactor is to be the first in the world to achieve a positive energy balance, which means that it will produce more energy during operation than it will use to keep the plasma heated.

Astronomers discover a supermassive black hole that traps 6 galaxies

The most recent supermassive black hole we have detected is located at the center of the SDSS J103027.09 052455.0 quasar. It has a mass of one billion times the mass of the Sun and such a powerful gravity that it traps as many as 6 galaxies closest to it. It should be emphasized that its gravitational tentacles extend over 300 times the diameter of the Milky Way. Interestingly, this black hole is a very old object that was formed only less than a billion years after the Big Bang.

A 500-megapixel camera for surveillance of pedestrians has been developed in China

60 million Big Brother cameras in China rely on artificial intelligence technology to recognize passersby. This is important because the system detects criminals and records any illegal activities. The bottleneck of the entire technology, however, is cameras that record images in low resolution. If there is little detail in the images, then the artificial intelligence has a problem with quick and correct face identification.

Smooth skin like a child of any age? Scientists have discovered the elixir of youth

Researchers at Washington State University in a study published in eLife magazine describe a new factor that acts as a molecular switch in the skin of young mice that is turned off when the skin is formed. Interestingly, the researchers managed to turn it on again, which resulted in faster wound healing without scarring - the newly formed skin was even covered with fur and had the ability to contract the paroparous muscles located at the base of the hair follicles, i.e. the popular goosebumps. - We were able to take the innate ability of a newborn's young skin to regenerate and transfer it to the old skin. We have shown that, in principle, this type of regeneration is possible, explains Ryan Driskell, one of the authors of the study.

Netflix has found itself in great trouble with content that sexualizes children

From the award at the Sundance Film Festival to criminal charges in Texas, the film "Stars" has come a long way, and although its director did not pay attention to that, the production is loud again.

Smart home even smarter. Xiaomi presents the Ultra Wide Band

And since smart home devices are an increasingly important part of Xiaomi's activity, going into Ultra Wide Band (UWB) communication technologies should not surprise anyone. Especially that it is a solution that serves not only for efficient data transmission between devices, using the 500 MHz band, but also for precise tracking of other devices, their distance and location. According to the manufacturer, its technology gives smartphones and other smart devices a completely new perceptual abilities, something like GPS in the interior.

Elon Musk announces the start of the colonization of the Red Planet in just 4 years

Elon Musk confirmed his earlier words that his company would start colonizing the Red Planet in 2024. We can take his plans seriously, because the most powerful space transport system in human history is to be ready for action next year. We are talking about the Starship ship and the SuperHeavy rocket.

Sony has yet to let go of 3D, here comes the amazing Spatial Reality Display

In cinemas we can still watch movies in 3D (and in this release it makes some sense, although some users still complain of headaches and discomfort caused by heavy glasses), but a similar trend in the case of home TVs disappeared sooner than it appeared. For a while, TV producers actually explored its possibilities, but customers ultimately did not show much interest, especially since the effects were not as good as in the cinema, so the subject died a natural death. It seems, however, that not for everyone, because Sony has just presented its 15.6-inch Spatial Reality Display panel with a 4K resolution, which offers eye tracking and the ability to watch 3D materials without the need to use VR glasses or goggles.
