Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem – a sugar-coated polymer nanoparticle – that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%. The glycosystem is a specially designed particle that mimics natural sugars found on human cells. These sugars, known as polysialosides, are made of repeating units of sialic …

Indoor light is an untapped source of energy for billions of small electronics. Devices like remote controls, keyboards, smoke alarms, and sensors spend their entire lifetimes in lit spaces but rely on batteries that need replacement. As the number of connected devices grows with the rise of the Internet of Things, replacing those batteries is becoming costly, labour-intensive, and environmentally …

Tahoe cofounders (L-R): Kevin Shokat, Nima Alidoust, Johnny Yu and Hani Goodarzi Tahoe Therapeutics One of the holy grails of biology is digitally simulating a living cell. If researchers can use computers to more accurately understand how new medicines would react in the body, that could give them greater confidence when they’re tested on animals and humans. But while large …

Summary: Scientists have identified a natural compound combination that reverses aging-related brain cell decline and removes harmful Alzheimer’s-linked proteins. The treatment, combining nicotinamide (vitamin B3) and the green tea antioxidant epigallocatechin gallate, restores guanosine triphosphate (GTP) levels—critical for neuronal energy and protein cleanup. In aged neurons, the restored energy boosted protein clearance, reduced oxidative stress, and reactivated key cell trafficking …

The worry that breast cancer may someday return is a troubling source of anxiety for many survivors of the disease. It’s understandable why, since most relapses and metastatic cancers (cancers that have spread) aren’t started by new tumours. Rather, they’re caused by sleeper cancer cells that suddenly awaken. These “dormant” cancer cells usually colonise places such as the lungs or …

A new case study offers a tantalizing glimpse into the potential future of transplantation medicine. A man with type 1 diabetes is now able to make his own insulin thanks to a transplant of gene-edited pancreatic cells—a transplant that hasn’t required the typical drugs used to avoid rejection. Scientists in Sweden and the U.S. conducted the research, published this week …

Shortened telomeres have been linked to aging. peterschreiber.media/Getty Images hide caption toggle caption peterschreiber.media/Getty Images It’s no secret that stress isn’t good for you. But just how bad is it? Well, in the last few decades, scientists have linked psychological stress to changes in our DNA that look a lot like what happens on the molecular level as we age. …

While chemotherapy remains a cornerstone of lung cancer treatment, it often weakens the immune system it relies on for long-term control. Now, researchers have found a way to turn this weakness into strength — by transplanting healthy mitochondria into the tumor environment. In advanced non-small cell lung cancer (NSCLC), combining mitochondrial transplantation with cisplatin not only enhanced immune cell infiltration …
