When someone is paralyzed from the neck down, it goes without saying that they can 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 interfa… Continue reading BCI lets paralyzed users quickly type text, by imagining writing it
In a relatively short space of time, perovskite solar cells have become a highly promising candidate when it comes to how we might generate electricity in the future, but there are some design problems to overcome first. These largely relate to stabili… Continue reading “Molecular glue” strengthens the weak point in perovskite solar cells
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.Continue Re… Continue reading Microbes may inhabit subsurface modern Mars, says geochemical study
Machines that connect to the human brain to gather and interpret its electrical signals have wide-ranging potential, from enabling paralyzed people control over robotic prostheses to supplementing human intelligence so it keeps pace with artificial int… Continue reading Groundbreaking implant wirelessly relays brain signals in high fidelity
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.Continue ReadingCategor… Continue reading Venus may have been without active tectonic plates for a billion years
Researchers at Brown University have developed a new way to make super-hard metals. The team made nanoparticle “building blocks” that could be fused together under moderate pressure, thanks to a chemical treatment.Continue ReadingCategory: Materials, S… Continue reading “Super-hard” metals forged in new nanoparticle manufacturing process
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. The technology overcomes one of the key… Continue reading Wrinkled graphene sheets offer a shortcut for water purification
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, or other technological advances… Continue reading Multi-link catfish skull may hold key to better underwater robots
A solid-state battery, where the liquid electrolyte that carries the charge is swapped out for a solid alternative, promises a number of performance benefits over today’s solutions, but there are a few problems to solve first. Scientists at Brown Unive… Continue reading Dash of graphene leads to “toughest” solid battery 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 nonetheless exist, a new one is claimed to provide a fuller, more nat… Continue reading New wrist replacement is claimed to move better, last longer
