The NASA Ingenuity helicopter successfully completed its second flight on Mars Thursday, and it was even more challenging than the first. Ingenuity had a longer, higher-climbing flight, including an angled and sideways trek.

NASA has logged another extraterrestrial first on its latest mission to Mars: converting carbon dioxide from the Martian atmosphere into pure, breathable oxygen, the U.S. space agency said on Wednesday.

Millions of tons of plastic end up in landfills every year. It's a big societal problem and an even larger environmental threat. In the United States, less than 9% of plastic waste is recycled. Instead, more than 75% of plastics waste ends up in landfills and up to 16% is burned, a process that releases toxic gases into the atmosphere.

Our research provides clear evidence pro-inflammatory diets are linked to poor health, including heart attacks, bowel cancer and depression.

Using pattern recognition and AI techniques "opens new window" to ancient world.

An instrument on Nasa's Perseverance rover on Mars has made oxygen from the planet's carbon dioxide atmosphere. It's the second successful technology demonstration on the mission, which flew a mini-helicopter on Monday. The oxygen generation was performed by a toaster-sized unit in the rover called Moxie - the Mars Oxygen In-Situ Resource Utilization Experiment.

The Lyrids meteor shower is about to arrive in the sky. Lucky watchers of the stars will be able to see meteors streaking across the night sky as they take in a celestial spectacle that has been observed by humans for thousands of years. They peak over the night of 21 April and into 22 April, which happens to be Earth Day. But they will be visible – if not quite so visible – in the days before and after that.

Designed for door-to-door transportation, ASKA comes with a hefty price tag.

The Ingenuity drone completes the first powered, controlled flight by an aircraft on another world.

Roscosmos chief Dmitry Rogozin said work had begun on the fist module of a new station, after officials warned that Russia was considering pulling out of the ISS, one of the few successful examples of cooperation with the West.

Senior officials are pessimistic about the station’s long-term future

AI has gone into games, self-driving and other areas with mixed success, and now it's trying its hand at cooking. After Google's AI went up against a Great British Bake Off winner, Sony has developed a deep learning system called FlavorGraph designed to pair up ingredients like garlic, olives and milk.

“The number of people that would be affected by this is about 40% of the world population.”

Walking is good for you, obviously. But can it whip you into shape?

Humans used nearly three-quarters of the Earth's land 12,000 years ago and colonization and industrialization brought negative effects, new research shows.

Researchers made human-monkey chimeras, by adding human stem cells to monkey embryos. Some embryos were cultured for 19 days after fertilisation.

Where ancient humans lived — and when — can be unveiled using DNA extracted from sediment layers dug from cave floors.

The active ingredient in magic mushrooms that gives them their psychedelic effect might be as good as, if not better than a leading drug used to treat depression, a new study suggests. Researchers from Imperial College, London compared the therapeutic potential of psilocybin - found in the mushrooms - with a six-week course of the antidepressant escitalopram in 59 people with moderate to severe depression.

Sharing our personal experiences on social media may negatively impact how we feel about our memories, especially if the post doesn't get many likes, a new study reports.

Emotion recognition technology can hurt people, both by working properly and enabling harassment, and also by not working accurately. Do we really want it?
