At the Japan Mobility Show, technology companies demonstrated a staggering number of gadgets, aircraft, robots and other machinery.
One invention in particular caught the attention of guests: a four-legged walking robot capable of carrying up to four passengers.
The SR-02, a prototype created by Japanese manufacturer Sansei Technologies, resembles a mixture of the AT-AT walker from the movie “Star Wars” and a rhinoceros. The novelty was designed for riding in amusement parks.
Humans breathe methane and nitrogen oxide, among other gases, and it is these gases that researchers have recently focused on to find out the extent and nature of our impact on the environment. While our CO2 is absorbed by plants and has a negligible impact on nature, CH4 and NO have a significant impact on global warming.
Scientists analyzed samples of these compounds emitted by 104 adult volunteers. It turned out that nitric oxide was excreted by all participants, while methane was excreted by only 31% of subjects, and it was more often excreted by women and subjects over thirty. It is not yet clear why the distribution was this way.
During an interview with podcaster Lex Friedman, Amazon founder Jeff Bezos stated that in the future, giant cylinder-shaped space stations could serve as habitable spaces for huge numbers of people. He expressed his desire to see a trillion people living in the solar system and emphasized that such a population would offer unique opportunities and potential for extraordinary minds.
This vision differs significantly from that of Ilon Musk, who aims to explore other planets and create a multi-planetary society.
Every year many asteroids approach the Earth at a distance smaller than the distance to the Moon, but catastrophic collisions are extremely rare. A new study conducted by experts from Sweden’s Luleå University of Technology suggests that our planet has some kind of defense system in the form of its powerful gravitational forces, and it is this system that copes with dangerous celestial bodies.
Researchers have been searching for years for near-Earth asteroids that have been blown to pieces, but they have been unable to detect them. According to scientists, any fragments that form in this way blend into the background so quickly that it is simply impossible to identify the family of such asteroids.
An entire universe made of “dark” particles may lie within our own, and scientists have a hunch about where to start looking for it. According to a publication in the arXiv preprint library, answers may be found in the mysterious hearts of so-called “mirror stars.”
It is noted that the mirror universe can be absolutely anywhere, being completely invisible to us. In the course of their research, scientists have found that mirror stars, in turn, can make themselves visible, but at the same time they will be visually different from everything that could be hitherto detected in the universe.
According to scientists, the formation of such stars occurs when different types of dark matter interact, lose energy and crumple. The corresponding process should occur by analogy with the formation of ordinary stars in our Universe, but the interaction between mirror stars would occur through their own forces of nature, and they would emit radiation in the form of invisible to us dark photons.
