Tumors driven by cancer-driving KRAS mutations are often susceptible to ferroptosis, a type of cell death that can be harnessed for cancer therapy. Given that more than 95% of pancreatic ductal adenocarcinomas (PDACs) harbor ...

Scientists at the University of Oxford have demonstrated, for the first time, that a key emotional center deep in the human brain directly influences how we interpret ambiguous social cues. In a new study, published in Neuron, ...

Just because a topical antiseptic is swabbed on the skin doesn't mean it stays on the skin. In a new study, Northwestern University scientists studied how a powerful antiseptic, called chlorhexidine, affects bacteria in hospital ...

New findings from VCU Massey Comprehensive Cancer Center and the VCU Institute of Molecular Medicine (VIMM), published in Pharmacological Research, show that an innovative drug effectively prevents prostate tumors from spreading ...

Researchers have demonstrated a new class of low-cost, scalable sensors that can be used to monitor electrical activity in human cerebral organoids. Because electrical signals are key to understanding brain function, this ...

Imagine being able to assess how healthy the front of our eyes are not only in hospitals, but also in remote eye-screening camps, elderly-care facilities, pharmacies, or even train stations. That is the future a research ...

The health benefits of cold-water immersion have been closely studied in recent years, thanks to the growing popularity of cold-water swimming. Now new research from the University of Chichester has found that as little as ...

Melbourne researchers have led the world's largest study confirming most patients labeled allergic to penicillin are not truly allergic. The study, described as a "game changer" by lead author Professor Jason Trubiano, demonstrates ...
