New technology can clean water twice as fast as commercially available ultrafiltration membranes. Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It’s highly efficient, long-lasting and environmentally friendly – and could provide clean water for those in need.

More than 1 in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas, which is why access to clean water is one of the National Academy of Engineering’s Grand Challenges. Engineers at Washington University in St...

A study by UCLA researchers is the first to demonstrate a technique for coaxing pluripotent stem cells – which can give rise to every cell type in the body and which can be grown indefinitely in the lab – into becoming mature T cells capable of killing tumor cells.

The technique uses structures called artificial thymic organoids, which work by mimicking the environment of the thymus, the organ in which T cells develop from blood stem cells.

T cells are cells of the immune system that fight infections, but also have the potential to eliminate cancer cells...

One day we may be able to ingest tiny robots that deliver drugs directly to diseased tissue, thanks to research being carried out at EPFL and ETH Zurich. The group of scientists – led by Selman Sakar at EPFL and Bradley Nelson at ETH Zurich – drew inspiration from bacteria to design smart, biocompatible microrobots that are highly flexible. Because these devices are able to swim through fluids and modify their shape when needed, they can pass through narrow blood vessels and intricate systems without compromising on speed or maneuverability...

A new antibiotic developed by a Flinders University researcher is being heralded as a breakthrough in the war against a drug resistant superbug. Bacteria are winning the fight against antibiotics as they evolve to fight off traditional treatments, threatening decades of advancements in modern medicine, with predictions they will kill over 10 million people by 2050. The scientific development of new, effective and safe antibiotics is crucial in addressing the ever-growing threat posed by drug resistant bacteria around the world.

Clostridium difficile infection (CDI) is a potentially deadly infection in the large intestine most common in people who need to take antibiotics for a long period of time, particularly ...
