Researchers have enabled a man who is paralyzed to control a robotic arm through a device that relays signals from his brain to a computer. He was able to grasp, move and drop objects just by imagining himself performing the actions.

Injuries to the articular cartilage in different joints, including the knee, are painful and limit mobility. Therefore, researchers are developing cartilage implants using cells from the patient’s nasal septum. A recent study shows that giving these cartilage implants more time to mature significantly improved clinical efficacy, even in patients with complex cartilage injuries. This suggests

A new study revealed that atmospheric gravity waves play a crucial role in driving latitudinal air currents on Mars, particularly at high altitudes. The findings, based on long-term atmospheric data, offer a fresh perspective on the behaviors of Mars’ middle atmosphere, highlighting fundamental differences from Earth’s. The study applied methods developed to explore Earth’s atmosphere

Researchers have created washable and durable magnetic field sensing electronic textiles — thought to be the first of their kind — which they say paves the way to transform use in clothing. This technology will allow users to interact with everyday textiles or specialized clothing by simply pointing their finger above a sensor.

Within the next decade, space agencies plan to bring samples of rock from Mars to Earth for study. Of concern is the possibility these samples contain life, which could have unforeseen consequences. Therefore, researchers in this field strive to create methods to detect life. Researchers have now successfully demonstrated a method to detect life in

Engineers devised a new method for designing metals and alloys that can withstand extreme impacts, which could lead to the development of automobiles, aircraft and armor that can better endure high-speed impacts, extreme heat and stress.

Whether it’s rivers cutting through earth, lava melting through rock, or water slicing through ice, channels all twist and bend in a seemingly similar back-and-forth manner. But a new study has discovered that channels carved by rivers actually have curves distinct to those cut by lava or ice.

Engineers have developed a method to utilize aluminum to improve performance of water electrolysis catalyst.

Experts see peer recognition as important to student success in physics, and a new study gives college-level physics instructors insight into how students perceive the message from their classmates that ‘you’re good at physics.’ Even when women receive similar amounts of recognition from peers as men for excelling in physics classes, they perceive significantly less

A newly developed pentanuclear iron complex can offer an efficient, stable, and cost-effective solution for water oxidation. By electrochemically polymerizing the complex, researchers have obtained a polymer-based catalyst, poly-Fe5-PCz, and achieved water oxidation with up to 99% Faradaic efficiency and exceptional stability, even under rigorous conditions. This breakthrough offers a scalable alternative to rare metal
