Does wearing a face mask help to prevent COVID? Four years after the pandemic began, here's what scientists have learned.

Question: If you could create an AI twin of yourself, would you?

In recent years, research teams worldwide have been trying to develop new flexible and soft electronics. These devices could have various potential applications, for instance helping doctors to monitor their patients' health conditions or supporting rehabilitation and performance sports.

On The Vergecast: AI never forgets, for better and for worse.

The U.S. small, high-altitude balloon posed no threat to national security, the military said Friday.

Five people were driving Thursday morning near a semi-centennial geyser thermal pool when it went off the road.

Four-legged animals are innately capable of agile and adaptable movements, which allow them to move on a wide range of terrains. Over the past decades, roboticists worldwide have been trying to effectively reproduce these movements in quadrupedal (i.e., four-legged) robots.

Sierra Butler was offered the opportunity to be just one of two people enrolled in a clinical trial looking at a therapy that could put her lupus into remission.

The world's first hydrogen-powered commercial passenger ferry will start operating on San Francisco Bay as part of plans to phase out diesel-powered vessels and reduce planet-warming carbon emissions, California officials said Friday, demonstrating the ship.

The image released Friday depicts two merging galaxies, nicknamed "the Penguin and the Egg," that are about 100,000 light years apart, a surprisingly close distance in astronomical terms.

RMS Titanic Inc. plans to use remotely operated vehicles to capture high-resolution images of the famed shipwreck.

Researchers at Songshan Lake Materials Laboratory have made significant advances in sodium-ion battery (SIB) technology by improving cycling performance of the NaNiO2 cathode. The work has been published in the online edition of Materials Futures.

Using electricity generated by offshore wind turbines as one pathway to split water to produce clean hydrogen may make economic sense, particularly along the U.S. Atlantic Coast and in the Gulf of Mexico, according to researchers at the National Renewable Energy Laboratory (NREL).

Scientists at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia have developed a tiny "claw machine" that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors.

A trio of computer scientists at Auburn University, in the U.S., working with a colleague from the University of Alberta, in Canada, has found that claims of visual skills by large language models (LLMs) with vision capabilities (VLMs) may be overstating abilities.

Water electrolysis offers an ideal process for hydrogen production, which could play a key role in the global energy transition that increasingly relies on renewable electricity, but whose current production process is extremely carbon intensive.

Vernestra Rwoh's lightsaber of choice is unlike anything we've seen on screen in Star Wars–but it has a long history in the old Expanded Universe.

Leslye Headland has seen your speculation about the unknown world Star Wars' latest villain calls home.

A team of roboticists and AI specialists at Google's DeepMind have demonstrated a robot capable of giving context-based guided tours around its offices. They have posted a paper describing their work, along with demonstration videos, on the arXiv preprint server.

The power-conversion efficiencies (PCEs) of organic solar cells based on compounds known as polymer donors and fused ring electron acceptors (FREAs) have recently exceeded 19%. In contrast, organic solar cells based on non-fused ring electron acceptors (NFREAs), more affordable compounds characterized by non-fused (i.e., separate) aromatic rings, have so far exhibited disappointing efficiencies of around 16%.
