World’s fastest microscope freezes time at 1 quintillionth of a second

Posted on by

A new electron microscope can effectively freeze time, snapping images of events just 1 attosecond long

The subatomic world is hard to image not just because it’s incredibly tiny, but super fast too. Now physicists at the University of Arizona have developed the world’s fastest electron microscope to capture events lasting just one quintillionth of a second.

Weight-loss power of oats naturally mimics popular obesity drugs

Posted on by

Let’s face it, dietary fiber is not the most scintillating topic, even though for the last 50 years it’s been well accepted that it’s valuable for good gut health. But we’re now coming to understand that fiber itself is an umbrella term, and one partic… Continue reading Weight-loss power of oats naturally mimics popular obesity drugs→

Nearby asteroid’s birthplace traced to specific crater on the Moon

Posted on by

Many asteroids can be traced back to their parent body – the planet or moon they broke off from. But for the first time, scientists now claim to have traced the origins of an asteroid back to the specific crater it was birthed from.Continue ReadingCate… Continue reading Nearby asteroid’s birthplace traced to specific crater on the Moon→

“Millennium Camera” to take a 1,000-year long-exposure photo

Posted on by

What did the spot of land you’re currently on look like 1,000 years ago? Well, people in the year 3023 might have the luxury of finding out, thanks to an art/science project called the Millennium Camera, which will take an extremely long-exposure photo… Continue reading “Millennium Camera” to take a 1,000-year long-exposure photo→

Key chemical found at the edge of galaxy suggests alien life is common

Posted on by

Phosphorus – a key ingredient for life as we know it – was thought to be relatively rare in space. But now, astronomers have detected a surprising amount of the stuff on the fringes of the galaxy, suggesting life may be more common in the cosmos.Contin… Continue reading Key chemical found at the edge of galaxy suggests alien life is common→

Brain waves driven more by remembering an event than the event itself

Posted on by

A new study has found that contrary to popular scientific belief, remembering an event drives the production of memory-related brain waves more than actually engaging in the event does. The finding could improve the treatment of memory loss in people w… Continue reading Brain waves driven more by remembering an event than the event itself→

Fairy-tale-inspired rovers could use “breadcrumbs” to map caves on Mars

Posted on by

Exploring the depths of an unmapped cave system is a daunting enough prospect on its own, but think how risky it would be to do so on another planet such as Mars. That’s why a new system is in the works, which would use “breadcrumb”-dropping rovers to … Continue reading Fairy-tale-inspired rovers could use “breadcrumbs” to map caves on Mars→

Flower-like pacemaker uses light for pain-free defibrillation

Posted on by

Ordinarily, pacemakers correct irregular heartbeats by delivering an electric shock to the entire heart – which can be painful. An experimental new one takes a different approach, and it does so by encompassing the heart with light-emitting “petals.”Co… Continue reading Flower-like pacemaker uses light for pain-free defibrillation→

Ancient Martian life may have died out in self-induced climate change

Posted on by

Humans might not be the first lifeforms in the solar system to face the threat of their own activity changing the climate of their home planet. A new model suggests that ancient Mars was once habitable enough to support methane-producing microbes, and … Continue reading Ancient Martian life may have died out in self-induced climate change→
