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.

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.

There are planets also outside our galaxy? We just discovered the first one

It turns out, however, that planets exist in other galaxies as well. While this is theoretically not a big deal for us, we haven't discovered any so far, so we couldn't be sure. Now that has changed. Astronomers calculate that there could be billions of exoplanets in the Milky Way. So far, we've only detected 4,000.

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.

See how a huge solar roof from Tesla is built in just 4 days

For nearly 3 years, Elon Muska has been offering very practical, ecological solutions for homeowners who want to be energy independent and at the same time do not want to mar the roofs of their houses with traditional solar installations. We are talking about the Solar Roof technology. These are solar panels integrated into the roof of the house.

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 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.

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.
