Gut bacteria by-products can trigger heart failure

A chemical produced by intestinal bacteria has been linked to heart failure, according to a new study. The chemical and heart risk link has been established previously, but the association with bacteria is new.

Is schizophrenia linked to human parasites?

There are many possible causes of schizophrenia, from genetic to environmental. One unusual factor could be, in some cases, parasites.

Is the protein furin the answer to stopping Ebola?

There are many investigations taking place into tackling the Ebola virus. One stream of research is looking into the protein furin. This protein is responsible for activating other proteins that allow the virus to spread within the human body.

HIV infection is based on viral-cell targets

Although the human immunodeficiency virus (HIV) inserts itself at different locations in a human cell, researchers have found that specific integration sites determine the speed that the infection spreads at.

U.S. lightning strikes to increase 50 percent as planet heats up

As man-made global warming continues to make the earth a warmer and wetter place, lightning strikes will also increase — by as much as 50 percent by the end of this century, scientists say in a new study.
