Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn’t stick to the wound (Nature Communications, "Superhydrophobic hemostatic nanofiber composites for fast clotting and minimal adhesion"). This marks the first time that scientists have combined both properties in one [...]
Scientists at the Okinawa Institute of Science and Technology Graduate University (OIST) have developed a light-based device that can act as a biosensor, detecting biological substances in materials; for example, harmful pathogens in food samples. Current industry-standard biosensors have limited sensitivity and precision. They can only detect cumulative effects of groups of particles, rather [...]
Some quantum computers and networks store their information in an electron’s spin, which can be up or down – like the zeros or ones in a conventional computer. They can also be a combination of both up and down. One way to manipulate the electron spins may be through using sound waves. The first [...]
The device uses lasers to accelerate electrons along an etched channel. In a full-scale particle accelerator, electrons fly along a kilometers-long path as microwaves bombard them, boosting the particles to near light speed. Such a high-energy electron beam, produced at facilities such as California’s SLAC National Accelerator Laboratory, enables a variety of experiments, including capturing extremely [...]
Researchers found a way to create lasers smaller than red blood cells. These microlasers convert infrared light into light at higher frequencies. Made from nanoparticles, these are among the smallest, continuously emitting lasers of their kind ever reported. The lasers constantly and stably emit light for hours at a time. They emit the light [...]
AS artificial intelligence technology continues to develop, like any new tech, questions begin to arise on its capabilities in warfare. Technology could ultimately be catastrophic for mankind. During an interview with Express.co.uk, he argued that A.I tech used in conflicts could quickly be categorized as a war crime similar to chemical and biological weapons. [...]
The University of Surrey has developed a robust multi-layer nano-barrier for ultra-lightweight and stable carbon fibre reinforced polymers (CFRPs) that could be used to build high precision instrument structures for future space missions. CFRP is used in current space missions, but its applications are limited because the material absorbs moisture. This is often released [...]
Scientists at the University of Otago in New Zealand say they have discovered how viruses that specifically kill bacteria can outwit bacteria by hiding from their defenses. These findings are important for the development of new antimicrobials based on viruses and provide a significant advance in biological knowledge, according to the researchers. Lead researcher [...]
Most synthetic materials, including those in battery electrodes, polymer membranes, and catalysts, degrade over time because they don't have internal repair mechanisms. If you could distribute autonomous microrobots within these materials, then you could use the microrobots to continuously make repairs from the inside. A new study from the lab of Kyle Bishop, associate [...]
For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite--the absence of resistance, or superconductivity. "The way electrons interact with each other [...]
