Whether they're being used for research or for restoring lost capabilities to the disabled, brain-computer interfaces (BCIs) show a lot of promise. They could soon be much more effective, thanks to the development of tiny new sensors.

When someone is paralyzed from the neck down, they can obviously no longer write words out by hand. They can still think about doing so, though, and those thoughts could allow them to type out messages via a new brain-computer interface (BCI).

Perovskite solar cells can suffer from stability issues and quickly deteriorate during use, but scientists at Brown University have come up with a way of addressing this by targeting a weak point with something they call molecular glue.

One of the main goals of NASA’s Perseverance rover is to scour the surface of Mars for signs of ancient microbial life. But a new study of the geochemistry of the Red Planet suggests that life could still be thriving below its surface today.

The team behind a project known as BrainGate have made a major breakthrough, demonstrating a wireless brain-computer interface that can read and transmit neural signals at a bandwidth that is on par with wired systems.

Venus may not have had Earth-like tectonic plates for the last billion years, according to the results of a new study. Instead, the planet, which is often referred to as Earth’s twin, may be covered in a single thick outer plate.

Researchers at Brown University have developed a new way to make super-hard metals, up to four times harder than usual. The team made nanoparticle “building blocks” that could be fused together under pressure, thanks to a chemical treatment.

Scientists at Brown University have demonstrated a promising new water purification technology that takes advantage of the tiny gaps in stacked sheets of graphene to filter out contaminants with great efficiency.

Even though they don't have flexible tongues, catfish are still able to rotate captured prey within their mouths. A new understanding of how they're able to do so could ultimately lead to more dextrous underwater robots.

Scientists at Brown University are reporting a new material that overcomes some of the key hurdles of solid-state batteries, using a delicate mix of ceramics and the wonder material graphene to produce the toughest solid electrolyte to date.

While we frequently hear about the replacement of arthritic hips and knees with implants, wrists are another matter, as they're very complex joints. And although artificial wrists do exist, a new one is claimed to provide a fuller range of motion.

Researchers have developed a new kind of wing that could dramatically improve the performance of small drones. Inspired by birds and insects, the wing has a leading edge that, as counterintuitive as it may seem, actually causes turbulence.
