How to shut down the power stations of cancer cells

An emerging nanomedicine cancer treatment involving the injection of tiny nanoparticles carrying compounds that can poison cancerous cells has many benefits. This so-called photodynamic therapy (PDT) is non-toxic and it doesn't ...

Gut epithelium muscles up against infection

To maximize absorption of nutrients from the diet, the intestinal mucous membrane has a large surface area. However, this also makes it vulnerable to attack from aggressive gut microbes. A new study by Uppsala University ...

Using AI to map how the brain understands sentences

Have you ever wondered why you are able to hear a sentence and understand its meaning—given that the same words in a different order would have an entirely different meaning? New research involving neuroimaging and A.I., ...
