A family tree can be very illuminating, but there can be some surprises in those branches, too. A recent mBio paper delves into the ancestry of Streptococcus agalactiae, a.k.a. Group B Strep (GBS), and uncovers some unexpected facts about the bacterium’s family history. Sørensen at al. examine... Read More
Researchers have engineered a fundamentally new approach to killing cancer cells.
The process uses small RNA molecules that can be programmed to attack only specific cancer cells; then, by changing shape, those molecules cause the cancer cells to self-destruct.
In conventional chemotherapy... Read More

Pathogenic bacteria have evolved a variety of mechanisms to avoid being killed by the immune systems of the humans and animals they invade.
Among the most sophisticated is that practised by mycoplasmas, which regularly change their surface proteins to confuse the immune system. Recent work i... Read More
