In research that could inform prophylactic treatment approaches for pregnant women at risk of Zika virus infection, investigators conducted experiments in mice and identified six Zika virus antibodies, including four that neutralize African, Asian and American strains of the mosquito-borne virus.…

Drugs that stop the overproduction of proteins by cancer cells may shut them down, but it also shuts down production of essential proteins in healthy cells. Researchers have found a protein with an active site that opens and initiates translation only when the protein binds to a small subset of…

Resveratrol, given to Alzheimer's patients, appears to restore the integrity of the blood-brain barrier, reducing the ability of harmful immune molecules secreted by immune cells to infiltrate from the body into brain tissues, say researchers. The reduction in neuronal inflammation slowed the…

By monitoring stem cell differentiation on gels that mimic the stiffness of biological tissue, researchers have identified the metabolites that stem cells use when selecting bone and cartilage fates. When fed to standard stem cell cultures, these molecules were then found to guide stem cells to…

A number of states – including Massachusetts and New York – mandate public reporting of mortality outcomes following certain cardiac procedures. While such reporting was originally intended to increase transparency and improve quality of care, a new study has shown that public reporting may in fact…

The human nose is a battleground for bacteria and some of them could prove to be our allies. Researchers have discovered a new antibiotic, produced by nose-dwelling bacteria, that kills antibiotic-resistant superbugs, including MRSA. The study, published in Nature, shows that the human microbiome —…

Research into Africa's first 'screen-and-treat' program for hepatitis B suggests the initiative may reduce deadly complications of the virus. The hepatitis B virus infects around 250 million people worldwide, and is transmitted through blood and bodily fluids. It is commonly transferred from mother…
