University of Leeds researchers have observed for the first time how HIV and Ebola viruses attach to cells to spread infection. The findings offer a new way of treating such viruses: instead of destroying the pathogens, introduce a block on how they interact with cells. They used ‘quantum dots’ that mimicked the shape of the viruses and acted as technological stand-ins in experiments to reveal how they bind to cells.

Quantum dots are fluorescent crystals in which the colour of the emitted light is dependent on the size of the crystal – one of several properties that has led to them becoming the most desirable component for the...

An extract of willow bark has shown to be one of the most potent longevity-extending pharmacological interventions yet described in scientific literature.

A new Concordia-Idunn Technologies research collaboration provides insights into how 6 groups of molecules can slow biological aging. For the study, the research team combed through Idunn Technologies’ extensive biological library, conducting more than 10,000 trials to screen for plant extracts that would increase the chronological lifespan of yeast.

Why yeast? Cellularly speaking, aging progresses similarly in both yeast and humans. It’s the best cellular model to understand how the anti-aging process takes place...

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.
