Figure illustrates puddles of localized quasi-condensates found using a quantum Monte Carlo simulation of trapped atoms in a disordered lattice. Individual puddles, consisting of 10-20 particles each, are incoherent relative to each other. The Bose glass is composed of these puddle-like structures. Credit: Ushnish Ray, University of Illinois

Using some of the largest supercomputers available, physics researchers from the University of Illinois at Urbana-Champaign have produced one of the largest simulations ever to help explain one of physics most daunting problems. “This result was a fantastic collaboration between theory and experiment,” explained Prof. Brian DeMarco. “One of the grandest and most impactful frontiers of physics is the quantum many-particle problem...

This new ‘smart cell patch’ is a proof of principle to treat millions of people with type-1 and advanced type-2 diabetes. For decades, researchers have tried to duplicate the function of beta cells, the tiny insulin-producing entities that don’t work properly in patients with diabetes. Insulin injections provide painful and often imperfect substitutes. Transplants of normal beta cells carry the risk of rejection or side effects from immunosuppressive therapies.

Now, researchers at the University of North Carolina at Chapel Hill and North Carolina State University have devised another option: a synthetic patch filled with natural beta cells that can secrete doses of insulin to control blood sugar levels ...

Thanks to the electrodes system a stable signal is obtained, which allows precise control like handling an egg without breaking. It allows the person to experience sensations, free mobility and is handled using the mind. It was created by the Mexican Max Ortiz Catalan, who lives in Sweden, the device becomes an extension of the human body through osseointegration, this means that it connects directly to the bone via a titanium implant, and thanks to the neuronal and muscle binding interfaces a robust and intuitive control of the artificial hand is achieved, this way just by thinking about it is possible to move the limb.

Magnus, a patient with an arm amputated above the elbow, is the first person to use tech...

PolyU’s invention utilizes an optical method called upconversion luminescence resonance energy transfer (LRET) process for ultrasensitive virus detection. It involves simple operational procedures, significantly reducing its testing duration from around 1-3 days to 2-3 hours, making it more than 10X quicker than traditional clinical methods. Its cost is around HK$20 per sample, which is 80% lower than traditional testing methods...
