The US Navy is building for itself an innovative and compact artificial sun

Although China and the United Kingdom are currently pioneers in artificial sun technology, it seems that the first compact devices will appear in the US military. At least these are the plans of the Pentagon, which has been investing sky-high funds in futuristic technologies of the future for several years in order to modernize the army in the reality of a growing threat from China.

Rapidly advancing climate change will make it difficult to explore outer space

Unfortunately, by accelerating the development of our civilization, we degrade the natural environment so much that, as a result, we actually limit our development. We may not see it yet, but it is already happening. Worst of all, it won't just apply to our planet. Astronomers inform that the effects of climate change will also affect the implementation of projects not related to the entire universe.

Donald Trump approves TikTok's deal with Oracle and Walmart but sets conditions

Most importantly, President Donald Trump himself, who was the direct cause of the problems of the Chinese company, agreed to sign the agreement. At the same time, the US Department of Commerce extended the time previously allotted to TikTok by one week, i.e. until September 27, for ByteDance to be able to finalize the contract (which does not change the fact that TikTok again filed a lawsuit against the US administration, citing violations of First Amendment rights). and political motivation of decisions). What does this contract look like? First of all, ByteDance will create a new company called TikTok Global, which will be responsible for TikTok's operations in the United States and most of its international users, with 20% of the shares owned by Oracle and Walmart.

Are bacteria helping animals sense our planet's magnetic field?

Several hypotheses and countless different studies are being considered, but the truth is that we still don't have an evidence-based answer to this question. A new article, published in the Philosophical Transactions of the Royal Society B journal, presents a novel approach to the subject, namely, it suggests that sensing a magnetic field may be the result of a symbiotic relationship between animals and a specific group of bacteria capable of orienting themselves along the lines of our planet's magnetic field. \"The search for the mechanism behind this is one of the last big frontiers in sensory biology, and is often described as looking for a needle in a haystack,\" explains Robert Fitak of the University of Central Florida, co-author of the new study.

This is the first movie in history where a black hole devours the surrounding matter

Last year, astronomers released the first-ever shadow image of the black hole event horizon at the center of the galaxy M87. It was made by the Event Horizont Telescope. We will never see the image of the black hole itself, because these objects have such powerful gravity that they absorb light that can illuminate them, and therefore remain in the shadows.

Pet owners are better at isolating during the CoVID-19 pandemic

New research by researchers at the University of York in the UK suggests that having a pet at home allowed subjects to go through coronavirus lockdown in better mental health, with a lower level of loneliness. Interestingly, research shows that the type of animal does not matter, because it can be a dog as well as a guinea pig. Nearly 6,000 people from the UK took part in the tests, 90% of whom declared having at least one pet, thanks to which it was possible to determine the importance of animals for our mental health.

Here is an impressive supernova in a galaxy 70 million light years away

When a star releases as much energy in a few days as our Sun for billions of years, it must be visible for a long time - this was the case of our today's heroine, whose self-detonation, like the best paparazzi, was observed by NASA's Hubble Space Telescope. Subsequently, all images taken by this intergalactic tool were assembled into a video that documents a massive explosion in a barred spiral galaxy NGC 2525 in the constellation Rufa, 70 million light-years away, discovered by William Herschel in 1791.

The smart windows of the future darken and become solar cells

We have already seen artificial windows from Samsung's SunnyFive startup, which are able to perfectly imitate the classic ones, e.g. in places where their installation is not possible, also in terms of sunlight. They produce the full spectrum of natural light, with the angle of incidence changing throughout the day, and according to their creators, we can also count on skin synthesis of vitamin D when indoors (without the risk of burns or skin aging), which is important in geographic regions where there is little natural light and it is virtually impossible to expose yourself to sufficiently long exposure.

The White House unveils a new initiative to protect US technology

The US government has announced a new program to protect sensitive technology, especially in the face of China's expansionist drive. This one is called the National Strategy for Critical and Emerging Technologies and will help prevent the sourcing of critical US intellectual property and sensitive technology from foreign rivals. The White House proposal assumes that technology companies will implement security protocols during the early stages of advanced technology development, and that the government will be involved in analyzing the risk of certain projects and determining whether certain technologies will go to allies or not.

Astronomers have indicated planets from which alien civilizations can observe us

Extraterrestrial life may or may not be believed, especially since we still have no evidence of the existence of alien civilizations to this day, but studies such as the latter provide useful data for organizations such as SETI and the Breakthrough Listen Initiative, which are still actively looking for such activity. To date, most of the exoplanets found by astronomers have been detected using the transit method - this involves observing the passage of a celestial body through the disk of another celestial body, because when a planet partially obscures a star, it can be detected by analyzing the slight fading of the star's brightness.
