The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. NASA sent a probe to find out why—by getting closer to the star than ever before.

Nature can’t run without parasites, and climate change is driving some to extinction. What happens when they start to disappear?

Three bursts of charged particles ejected from the sun have merged into a wave that could lead to brilliant auroras being visible from Moscow to Oklahoma City.

Neuralink experienced a mechanical issue with its first human brain-computer interface implant. Its novel design may make it more prone to failure.

Anyone found guilty of selling or manufacturing cultivated meat in Alabama will face up to a three-month jail sentence and $500 fine.

Green spaces significantly cool our ever-hotter cities. New research suggests more trees could cut heat-related ER visits in LA by up to two-thirds.

Independent presidential candidate Robert F. Kennedy Jr. had both a brain parasite and mercury poisoning at the same time. Just how rare is each condition?

The world of clitoral suction sex toys is getting bigger every day. We’ve tested dozens, and these are our favorites.

Seven years behind schedule, this month Starliner will send two astronauts to space on a mission for NASA. The troubled company still has lots of catching up to do.

It’s not the technology itself. It’s that we don’t yet have enough trained workers to install heat pumps for full-tilt decarbonization.

Synthetic DNA could be used to spark a pandemic. A move by President Biden aims to create new standards for the safety and security of mail-order genetic material.

Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off moons and planets.

Hydrostor, a leader in compressed-air energy storage, aims to break ground on a 200-MW plant in New South Wales by the end of this year. It wants to follow that with a 500-MW facility in California.

On Star Wars Day, we use some basic physics to measure the power of the Force. It’s strong!

With little incentive for US farmers to test their cattle, and many undocumented laborers on dairy farms, the full scale of the outbreak is unclear.

Scientists are forecasting 11 North Atlantic hurricanes this year, five of them being major. Here’s what’s turning the storms into increasingly dangerous behemoths.

China's brain-computer interface technology is catching up to the US. But it envisions a very different use case: cognitive enhancement.

Britain’s former climate adviser says the country’s future plans are weak, climate protests are no longer helpful, and working closely with Big Oil is a jarring necessity.

Physicists call the dark energy that drives the universe “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years.

Climate change is increasing the number of days people are exposed to hazardous pollution, affecting already disadvantaged communities the most.

The far-traveled space probe is once again transmitting usable data, after a glitch caused months of gibberish.
