An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices.

Current semiconductor technology uses electronic charge or spin to store and process information; the associated technologies are called electronics and spintronics, respectively...

Another ancient star has been found lurking in the Milky Way. Around 35,000 light-years away, a red giant star named SMSS J160540.18–144323.1 was found to have the lowest iron levels of any star yet analysed in the galaxy.

This means that it’s one of the oldest stars in the Universe, probably belonging to the second generation of stars after the Universe burst into existence 13.8 billion years ago.

“This incredibly anaemic star, which likely formed just a few hundred million years after the Big Bang has iron levels 1...

Study also looks at effect of leaky gut on concentration. Fatty food may feel like a friend during these troubled times, but new research suggests that eating just one meal high in saturated fat can hinder our ability to concentrate – not great news for people whose diets have gone south while they’re working at home during the COVID-19 pandemic.

The study compared how 51 women performed on a test of their attention after they ate either a meal high in saturated fat or the same meal made with sunflower oil, which is high in unsaturated fat.

Their performance on the test was worse after eating the high-saturated-fat meal than after they ate the meal containing a heal...

Astronomers have detected elusive pulsation patterns in dozens of young, rapidly rotating stars thanks to data from NASA’s Transiting Exoplanet Survey Satellite (TESS)...
