Proof of life: Reevaluating oldest known Archean trace fossil for indications of early biology

In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite (a calcium titanium silicate mineral) microtextures found in 3.45 billion-year-ol... Read More

The protective milk shot – How mother’s milk protects piglets from parasite infections

Coccidiosis is a serious disease in new-born piglets. Caused by the parasite Cystoisospora suis, it exclusively infects pigs and often causes severe diarrhoea in suckling piglets. Parasitologists at the Vetmeduni Vienna have developed a new strategy for protecting the piglets: They infected sows... Read More

A WORD on the constraints of influenza virus evolution

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

Cancer-Causing HPV Virus Directly Damages DNA

Human papillomavirus (HPV) can damage chromosomes and genes directly, researchers report in a new study. HPV is a virus that can cause anal, cervical, head and neck cancers, and according to experts, it produces two viral proteins (E6 and E7) that are involved in the development of those diseas...

How the Body’s Cells Hold on Tight

When I was nine, biology gave me my first existential crisis. If I am built out of trillions of tiny cells, I worried, what’s to keep me from crumbling into a pile like a dried-out sandcastle? Almost two decades later, as a Ph.D. student in mathematics at the University of California, Davis, I’m... Read More

Dueling Infections: Parasitic Worms Limit the Effects of Giardia, and Vice Versa

If the idea of hookworms makes you shudder, consider this: Those pesky intestinal parasites may actually help your body ward off other infections, and perhaps even prevent autoimmune and other diseases.

To combat the overuse of antibacterials, stop using the absolutely terrible word, "antibiotic"

There are many reasons why bacteria evolve resistance to antibacterials, but one of the preventable reasons is the over-prescription of antibacterials to patients who don't have bacterial infections. But how to get people to stop asking for antibacterials? My suggestion is to stop using the wor... Read More
