Scientists have developed a biorobotic arm that can mirror human tremors, such as those experienced by individuals that live with Parkinson's disease. Artificial muscles on either side of the forearm contract and relax to suppress the involuntary shaking of the wrist and hand. The researchers see their biorobotic arm not only as a platform for other scientists in the field to test new ideas in exoskeleton technology. The arm also serves as a test bed to see how well artificial muscles known as HASELs can one day become the building blocks of wearable devices. The vision is to one day develop a sleeve that tremor patients can comfortably wear to be able to better cope with everyday tasks such as holding a cup.

A team of researchers created Morpho, an open-source programmable environment that enables researchers and engineers to conduct shape optimization and design for soft materials. Applications can be for anything from artificial hearts to robot materials that mimic flesh and soft tissue.

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping.

Research has achieved a breakthrough in eco-friendly display technology, creating highly efficient and stable blue quantum dot LEDs (QLEDs) that could power the next generation of televisions, smartphones, VR headsets and energy-efficient lighting -- without using toxic heavy metals.

A new seismic study of Singapore could guide urban growth and renewable energy development in the coastal city nation, where 5.6 million residents live within an area of 734 square kilometers.

Cement manufacturing and repair could be significantly improved by using biocement-producing bacteria, but growing the microbes at construction sites remains a challenge. Now, researchers report a freeze-drying approach that preserves the bacteria, potentially allowing construction workers to ultimately use powder out of a packet to quickly make tiles, repair oil wells or strengthen the ground for makeshift roads or camps.

Antimalarial drug resistance is a pressing issue in combating the spread of malaria worldwide. In a new study, researchers discovered a key process where malarial parasites take up a human blood cell enzyme, which could provide a new approach for antimalarial treatment.

Walking into your favorite restaurant and seeing a robot chef in the kitchen may seem far-fetched, but new research suggests that bots could be a solution to persistent labor shortages in the industry.

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 that the method could also be suitable for the treatment of degenerated cartilage in osteoarthritis.

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.

Engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging or mishandling whatever it holds.

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 peer recognition, the researchers found.

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 catalysts, advancing hydrogen production and energy storage for renewable energy.

Concrete structures in Japan capture and store about 14% of the CO2 emissions released during cement production, according to a new study. Their findings provide crucial insights for offsetting CO2 emissions from cement production, which is responsible for approximately 8% of global carbon emissions.

Working at nanoscale dimensions, billionths of a meter in size, a team of scientists revealed a new way to measure high-speed fluctuations in magnetic materials. Knowledge obtained by these new measurements could be used to advance technologies ranging from traditional computing to the emerging field of quantum computing.

Mining of polymetallic nodules from the seabed might lead to significant and long-lasting ecological changes -- both in the mined area, where surface sediments and the fauna living in and on it are removed along with the nodules, and on the adjacent seafloor, where the sediment suspended by the mining resettles.

Proteins play a key role in the life sciences -- from basic research and biotechnological applications to the development and manufacturing of pharmaceuticals. Scientists have developed a method that relies on physics rather than conventional chemistry to obtain the proteins that are needed for this purpose. Using short-wave, UV light invisible to humans, they have succeeded in purifying proteins from cell extracts or cultures. This technique is more efficient and gentler than previous methods.

A research team has developed a groundbreaking new method of producing carbon fiber while drastically reducing its energy footprint.
