Antibiotics were one of the most important inventions of the 20th century, but bacteria are developing resistance to them. Now researchers have shown that ultrashort pulses of laser light can kill bacteria and viruses, without harming human cells.

Spider silk is one of nature’s most impressive materials, exhibiting impressive strength and toughness. Now, researchers at Washington University in St. Louis claim to have created an artificial version that can outperform some natural spider silks.

Researchers have found a way to maintain insulin levels in diabetic mice by growing and implanting new beta cells that produce the hormone. These cells are housed inside a tiny device that protects them from the immune system, like a shark cage.

A new design out of Washington University in St Louis demonstrates a promising path forward for sodium batteries, with the team producing a device that is smaller and less expensive than lithium batteries, without compromising on performance.

​Hooking our brains up to machines could mean new forms of treatment for brain diseases such as Alzheimer’s. A new device shows promises in this regard, with an ability to be loaded up with different cartridges depending on the treatment needed and triggered remotely with a smartphone.

​Immunotherapy is a form of cancer treatment that seeks to supercharge the body’s natural immune defenses, but pancreatic cancer is one that has so far been able to evade its advances. Scientists are now reporting a discovery that might help the immune system regain the upper hand.

Tuberculosis is currently curable, but the bacteria responsible for it are fast evolving resistance to our antibiotics, thwarting attempts to keep the disease under control. Scientists have found a new compound that can boost the power of existing antibiotics and even reverse the bugs’ resistance.

A possible diabetes cure could be found by replenishing a patient’s own supply of beta cells, which naturally produce insulin. Researchers at Washington University in St. Louis are a step closer to that kind of treatment, after tweaking the recipe for turning stem cells into beta cells.

Water filters get less effective as bacteria builds up on their surface. Now, researchers at Washington University in St. Louis have developed a new type of membrane that reduces such biofouling by actively killing bacteria with graphene – and in an interesting twist, it’s built by bacteria.

We might be losing the war against bacteria, as they rapidly develop resistance to our best drugs. Now researchers from Washington University in St. Louis have found a way to potentially prevent bacteria from spreading antibiotic resistance to each other.

A new study suggests that the mantle is home to much more water than was previously believed. Seismic activity around the Mariana Trench have revealed that subducting tectonic plates are dragging more water deeper into the Earth, which could change our understanding of the global water cycle.

The blood-brain barrier is an effective shield against infection, but it’s not so helpful when you’re trying to get drugs in there. Nasal sprays could bypass the barrier, and now researchers have developed a way to use ultrasound pulses to drive the drugs to where in the brain they’re needed.
