Skycharge, developed by Green Motion and Pipistrel, has recently been approved by the European Aviation Safety Agency (EASA) as the world’s first OEM-independent electric aircraft charging station.

Pipistrel’s Velis Electro aircraft had already become the first electric aircraft to receive a type certificate from EASA in June last year. The approval of Skycharge is another important milestone on the way to environmentally sustainable aviation.

Skycharge is based on Eaton’s proprietary DC charging technology. The charging infrastructure for electric aircraft and eVTOL (electric Vertical Takeoff and Landing) aircraft offers exceptional conversion efficiency (over 96%), compactness and power density.

The only place in the Universe where we know life exists is on Earth. However, with billions of other star systems in the universe, it may not be the best place for life. In a new study, astronomers modeled the potential for life on other watery planets and discovered some conditions that can create oceans that are optimal for habitability.

The model suggests that watery planets with dense atmospheres, continents, and long days — planets that rotate slowly — were the most suitable for life. These conditions increase ocean circulation, which brings nutrients from the depths to the surface, where they can be used by organisms.

“[The research] shows us that conditions on some exoplanets with favorable ocean circulation patterns could be better suited to support life that is more abundant or more active than life on Earth,” Stephanie Olson, a University of Chicago researcher who lead the new study, said in a press release.

No one can stay awake forever. While we’re awake, our need for sleep gradually increases. If we deprive ourselves of sleep, our brain functions – such as attention or judgement – are impaired, and sleep becomes irresistible. No matter whether we are on a couch or at work – if we ignore our need for sleep, we ultimately crash.

Although sleep is vital, until now it hasn’t been known which structure of the brain tells us when we are tired. But our recent study has shown in laboratory mice that the cerebral cortex, which is responsible for the most complex brain functions – including perception, language, thought and episodic memory – helps us track our need for sleep.

A new report about artificial intelligence and its effects warns AI has reached a turning point and its negative effects can no longer be ignored.

The big picture: For all the sci-fi worries about ultra-intelligent machines or wide-scale job loss from automation — both of which would require artificial intelligence that is far more capable than what has been developed so far — the larger concern may be about what happens if AI doesn’t work as intended.

NASA Turned a Star’s Corpse into Sound — and It’s Magical.


We all know that there’s no sound in space. However, one project from NASA is turning that fact on its head by transforming images of space objects into beautiful music.

It’s all a part of a “sonification” project by the agency’s Chandra X-ray Observatory and the Universe of Learning program, according to a NASA blog about the topic. The project takes normal charts and images of space and transforms them into sound.
