Some types of restricted and repetitive behaviors become more prevalent among autistic children and teenagers over time, depending on their age and intellectual ability, whereas others decrease, two new studies show.

The results lend fresh support to the argument that restricted and repetitive behaviors — a core diagnostic trait that includes repetitive movements, insistence on sameness, sensory sensitivities and restricted interests — are too diverse to be lumped together.

“This is a complex behavioral domain that comprises several different subdomains that likely have different causes and might respond to different treatments,” says Mirko Uljarević, senior research fellow at the University of Melbourne in Victoria, Australia, who led one of the studies.

Bumps in detector could point to new physics.

Physicists turned on a new type of gravitational-wave sensor and saw two intriguing results, but they aren’t yet ready to claim a discovery.

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.

Objective reality exists, but what can you know about it that isn’t subjective. According to some neuroscientists, not much.

A clinical trial is beginning tomorrow to discover if it is safe to give radiotherapy in two large doses.

If successful, it would mean treatment for prostate cancer could take days instead of weeks.

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.

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.
