The stomach-dwelling bacteria Helicobacter pylori survives in the stomach—a hellish, churning vat of hydrochloric acid—by holing up inside that organ's pitlike glands and establishing squatter's rights. Once the germ has set up shop, Stanford University School of Medicine investigators have learned, even competing strains of the same species can't displace it, or even share its hideout.

Study on explosive volcanism during ice age provides lessons for today's rising CO2

A University of Oklahoma-led study recently found that explosive volcanic eruptions were at least 3-8 times more frequent during the peak of the Late Paleozoic Ice Age (~360 to 260 million years ago). Aerosols produced by explosive volcanism helped keep large ice sheets stable, even when CO2 levels increased, by blocking sunlight. But the volcanic emissions also may have started a cascade of effects on the climate system that resulted in additional CO2 removal from the atmosphere.

Spider venom is a dangerous cocktail

Spider venom does not only consist of neurotoxins but also of a multitude of dangerous constituents. Researchers of the University of Bern present a summary of many years of spider venom research in a new study and show how various substances present in spider venom interact with each other and thus effectively render the spider's prey defenseless.
