Your chin is an evolutionary accident

Chimpanzees, humans’ closest living relatives, do not have a chin. Neither did Neanderthals, Denisovans, or any other extinct human species. Humans, it turns out, have...

Astronomers watch a giant star quietly collapse into a black hole

Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but by quietly collapsing into...

Smart earbuds could soon detect early signs of cognitive decline

Earbuds may soon do much more than play music or take phone calls. According to a new international study, the same devices millions of people...

Astronomers discover “inside-out” planet system that defies cosmic rules

Astronomers have discovered a surprising planetary system that does not follow the usual rules of how planets form. The finding, led by researchers from the...

New device can hide your heartbeat from radar surveillance

Imagine sitting at your desk during a normal workday. You log into your computer, unaware that a built-in sensing system could be tracking your...

Scientists identify key bottlenecks slowing sodium-ion batteries

Sodium-ion batteries are emerging as a promising alternative to today’s lithium-ion batteries. While lithium-ion technology powers everything from smartphones to electric cars, lithium is relatively...

New compact device turns sunlight and waste heat into clean hydrogen at 28% efficiency

Hydrogen is often described as a fuel of the future because when it is used, it produces only water instead of harmful emissions. But making...

How big can a planet get? Scientists have new answers

When it comes to planets, bigger is not always easier to understand. The largest planets in the universe are gas giants—massive worlds made mostly...

How 3D printing is making energetic materials safer and more predictable

Making energetic materials—such as explosives, propellants, and fireworks—is a bit like baking a very sensitive cake. The ingredients must be carefully measured, the mixing must...

Scientists turn desert sand into eco-friendly bricks to cut cement emissions

Cement is one of the most widely used building materials in the world, but it comes at a high environmental cost. Portland cement alone is...

Can life begin on a moon without a sun

Free-Floating Planets, or as they are more commonly known, Rogue Planets, wander interstellar space completely alone. Saying there might be a lot of them...

Edison’s lost battery idea gets a high-tech comeback for the renewable energy age

At the start of the 20th century, electric cars were more common on American roads than gasoline vehicles. In 1900, many drivers relied on lead-acid...

Scientists discover 15,000-year-old viruses in Tibetan glacier ice

Most of the viruses were previously unknown to humans, study finds. Scientists who study glacier ice have found viruses nearly 15,000 years old in two...

Scientists develop robust molecule to boost performance and stability of organic electronics

Chemists at RIKEN have developed a new molecule that significantly enhances the performance of organic electronic devices while being more stable than previous alternatives. This...

Scientists create power-efficient memory using atom-thin materials

Scientists at the University of Rochester are pushing the boundaries of computing technology with a groundbreaking development in memory systems. Published in Nature Electronics, their...

Scientists find new way to create colloidal diamonds

The colloidal diamond has been a dream of researchers since the 1990s. These structures -- stable, self-assembled formations of miniscule materials -- have the potential...

Scientists perform the coldest reaction in the known universe

In temperatures millions of times colder than interstellar space, Harvard researchers have performed the coldest reaction in the known universe. But that's not all....
