Blood-pressure-lowering drugs should be offered to anyone old enough to be at risk of a heart attack or stroke (or who is otherwise known to be at risk), regardless of their blood pressure, according to the largest analysis of blood pressure trials to date.

Overfishing and disease have decimated shellfish populations in many of the world's temperate estuarine and coastal ecosystems. Scientists have now discovered another serious threat to these valuable filter feeders -- rising levels of atmospheric carbon dioxide that contribute to the acidification of open ocean, coastal and estuarine waters.

Bacteria are experts at adaptation: as soon as they have infected an organism, they adapt their metabolism to that of their host and produce substances which protect them from the body's immune defenses. How they do this is still unknown in the case of many types of bacteria.

An emerging form of the pathogenic yeast Candida is able to complete a full sexual cycle in a test tube, even though it's missing the genes for reproduction. And it may also do so while infecting us, according to researchers.

Scientists have discovered that cells use a very simple phase transition -- similar to water vapor condensing into dew -- to assemble and localize subcellular structures that are involved in formation of the embryo.

A new species of yeast has been discovered deep in the Amazon jungle. Biologist have identified novel characteristics of Candida carvajalis sp. nov.

The amino acid glutamine, found in many foods as well as in dietary supplements, may prove beneficial in offsetting gastric damage caused by H. pylori infection.
