The capsule intentionally skipped like a stone off the atmosphere to make its reentry easier.

As the party season kicks in, so will the effects of having one too many. Here are the sobering facts behind hangovers and tactics that might help you avoid them“Alcohol is a ‘dirty drug’,” says Emily Palmer, a researcher at Imperial College London, who studies hangovers. “It impacts multiple systems in the brain.”Scientists are not exactly sure what is going on in our bodies during a hangover, but they do know it is caused by a variety of biochemical and neurochemical changes. “It doesn’t just affect the liver or the brain,” says Palmer, “it affects almost every organ...

Best Buy is offering a $150 discount on the MacBook Air M2, even though it only came out this year.

It was one of the first famous images revealed by the James Webb Space Telescope earlier this year: a stunning shroud of gas and dust illuminated by a dying star at its heart.

Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. Today, it's a barren Arctic desert, but back then it was a lush landscape of trees and vegetation with an array of animals, even the now extinct mastodon.

The Orion spacecraft, which is to carry astronauts to and from the moon in coming years, will splash down in the Pacific Ocean Sunday after a test flight with no crew aboard.

It’s important for patients to know past relapses don’t define you, and ongoing help from professionals and friends is critical to recoveryThe modern mind is a column where experts discuss mental health issues they are seeing in their workBen* has been battling a drug and alcohol addiction for more than a decade. At 32 years old, he has experienced more than the average person his age.Ben suffered a horrific injury in a car accident when he was 21 and became dependent on painkillers. From there, he tells me in his first group therapy session in rehab that he began experimenting with a range...

Manipulating your body clock can improve health and productivityIt’s 8.30pm on a gloomy November evening and I’m sitting on the sofa under a tartan blanket and wearing a pair of orange-lensed specs. My other half regards me with bemusement. A man who disapproves of paracetamol and plasters, Tim has lived through my audio-bathing phase, my steps-tracker phase and the notorious 2015 installation of our bedroom air-quality monitor, a period during which I informed him he should breathe out less carbon dioxide (could he, I asked, just tape his mouth in bed at night so I didn’t wake up groggy...

A volcano in the Andes in Chile's north rumbled to life early Saturday, triggering minor earth tremors and sending a plume of smoke and ash 6,000 meters (nearly 20,000 feet) into a clear sky.

The world's next global pact for nature is doomed without clear mechanisms for implementing targets, conservation groups said Saturday on the sidelines of UN talks, as hundreds of protesters took to the streets of Montreal demanding greater action.

After making a close pass at the Moon and venturing further into space than any previous habitable spacecraft, NASA's Orion capsule is due to splash down Sunday in the final test of a high-stakes mission called Artemis.

A Tokyo company aimed for the moon with its own private lander Sunday, blasting off atop a SpaceX rocket with the United Arab Emirates' first lunar rover and a toylike robot from Japan that's designed to roll around up there in the gray dust.

Sandrine Rousseau is using her talent for grabbing headlines with provocative ideas to shift the focus of the national debate from the themes favored by the far-right to climate change and #MeToo.

The proposed deal would resolve thousands of lawsuits in multidistrict litigation based in Northern California.

Climate change is reshaping the American economy. New Mexico is leaning on ecotourism and sustainable industries to see it through, but extreme weather keeps getting in the way.

A “major storm system” approaching the Pacific Coast is forecast to rumble across the U.S., dealing feet of snow in the West, blizzard conditions in the Northern Plains and tornadoes across the South, forecasters say.

Webb telescope 'fingerprints' earliest galaxies

To design drugs that stall the growth of aggressive cancers, it helps to know the structures of the proteins that are revving the cancers' engines.

People dealing with the most socioeconomic disadvantages in greater Los Angeles also face higher levels of toxic air pollution, according to a new UCLA-led study.

A surprising discovery from the University of Virginia School of Medicine has torpedoed a key principle used in the development of new drugs to treat diseases. The finding could speed the drug-development process and help prevent potentially harmful drug interactions.

To save the northern white rhinoceros from extinction, the BioRescue team is racing to create lab-grown egg and sperm cells of the critically endangered subspecies. The team has now reported a milestone in Science Advances: they have generated primordial germ cells from stem cells—a world's first.

More than 90% of marine species are undescribed and many may go extinct due to human activity before they're discovered—the loss of unique, potentially valuable genetic resources resulting in unpredictable effects on global ecosystems essential to human food supplies and climate regulation.

Rising temperatures and increasing droughts have scientists looking for ways to better predict how plants will react to stress. Every study offers a little more information. Now, scientists have discovered a way to yield a wealth of insights in a single study. Combining three advanced research techniques that are rarely used together, they found they could pinpoint how different types of plants protect themselves from harsh conditions. Even more surprising? Plants try various strategies to assure their survival.

Non-metal nitrides are compounds in which nitrogen and non-metallic elements are linked by covalent bonds. Because of their technologically interesting properties, they have increasingly become the focus of materials research. In Chemistry—A European Journal, an international team with researchers from the University of Bayreuth presents previously unknown phosphorus-nitrogen compounds synthesized under very high pressures.

Quantum chemistry is very hard. The best quantum computing chemistry seems to be at the level of 12 qubits / 12 atoms. Supercomputer simulations can handle 20 qubits and 20 atoms simulation. There are early papers that suggest classical supercomputers can get to 100 atoms and 1000 qubit for some types of simulation. Quantum computers ... Read more
