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.

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.

The Rolls-Royce ACCEL electric plane has successfully completed ground tests

Last year, Rolls-Royce shared with us its plans to create the fastest electric plane in the world - and now the company announced that ACCEL (Accelerating the Electrification of Flight), because we are talking about it, has successfully completed all ground tests, so it's time to think about it about taking to the air. For people who have not heard about this one-man unit yet, the manufacturer aims at a drive based on three 750R engines, which will translate into 500 horsepower of power. The battery pack consisting of 6,000 individual cells will be responsible for supplying energy to work, which will provide a range of 320 kilometers on a single charge.

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.

The cancer breath test is already 80% effective

The team has developed a breath test that can monitor the exhaled air for head and neck cancer profiles and is highly effective at an early stage of testing. We have seen some promising breathing tests in recent years, many of them based on the analysis of volatile organic compounds (VOCs) in the exhaled air, where specific patterns can be observed when the body's metabolism is disturbed by disease. Attempts to detect and classify these respiratory biomarkers are becoming more and more effective, and we have recently heard of, for instance, successful tests for the detection of esophageal, stomach and lung cancer.

See how Unitree A1, the newest robo-dog straight from China, dances

The newest Unitree A1 is a machine with amazing capabilities. The robot is much smaller and lighter than SpotaMini, but at the same time it is not inferior to it in key issues, namely moving in even the most difficult terrain. In addition, the machine can work on batteries continuously for 4 hours. Today they will be able to see him in the footage, where the engineers showed his dancing skills.

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.

Historic NASA mission completed successfully. The probe took a sample from the asteroid

The OSIRIS-REx probe took a rock sample from the surface of the mysterious Bennu asteroid. There would be nothing extraordinary about it, if not for the fact that the entire project was 200 million kilometers from Earth, and that NASA scientists were performing such an unusual task for the first time.

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.
