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.

The Mars 2020 rover will be touching down in Jezero Crater and now there’s more evidence this was a good choice. Two new studies have found that the landing site is rich in minerals that could preserve fossils of ancient microbes and other lifeforms.

New technology known as Portal-ble allows the users of smartphone-based AR systems to put their hands in the picture.

Scientists are getting good results at repelling mosquitoes using graphene.

Imagine if you were working with a robot that could leave you written messages, or draw diagrams to explain concepts. Such a scenario has come a step closer to reality, as a university student has taught a robot how to copy what we write, and what we draw.

Hospital-acquired infections are a serious problem, and the most common type of such infections occurs when catheters are inserted into blood vessels. A new coating, however, shows promise for killing bacteria at insertion sites, keeping them from establishing biofilm colonies on the catheters.

​In recent years, a brain-computer interface (BCI) developed by the US BrainGate consortium has allowed people to control a robotic arm and to type, using only their thoughts. Now, a group of paralyzed volunteers has utilized the technology to perform various functions on a tablet.

Scientists have long debated the cause of the distinctive grooves on the surface of Mars' moon Phobos. One leading theory has it that the lines are signs of structural failure. But a competing idea suggests the marks may be superficial, caused simply by rolling stones on Phobos' surface.

A team of Brown University scientists has developed a new catalyst that could make hydrogen fuel cell​-powered vehicles more economical. Based on nanoparticles made of an alloy of platinum and cobalt, the new catalyst is cheaper than pure platinum, and also more efficient and longer lasting.

A NASA team has found definitive evidence of water ice at the poles of the Moon. Using data from NASA's Moon Mineralogy Mapper aboard the Indian Chandrayaan-1 lunar orbiter, the new discovery indicates that not only is water present on the Moon, but it is readily accessible from the surface.

"Giant” cancer cells contribute to many of the disease’s most dangerous abilities, but they remain relatively unstudied. Now, researchers from Brown University have investigated these troublemakers, revealing some physical characteristics that could eventually unlock new forms of treatment.
