An expedition to one of Asia's most isolated jungles – in the mist-shrouded Foja Mountains of western New Guinea – discovered a virtual ''Lost World" of new species, giant flowers, and rare wildlife that was unafraid of humans.

Alzheimer disease has a genetic cause in up to 80 percent of cases, according to a University of Southern California-led study of nearly 12,000 twin pairs.

A new tool to predict epidemics of malaria up to five months in advance has been developed by a scientist at the University of Liverpool.

Cleaning bathrooms may become a thing of the past with new coatings that will do the job for you.

Viruses and humans have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse.

A new technique in which single strands of synthetic DNA are used to firmly fasten biological cells to non-biological surfaces has been developed by researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley. This technique holds promise for a wide variety of applications, including biosensors, drug-screening technologies, the growing of artificial tissues and the design of neural networks.

A Mayo Clinic research team has challenged the accepted theory on the cause of sepsis -- a condition in which the body's cells generate fever, shock and often death. Sepsis is thought to occur when poisons from bacterial infection interfere with the cells.

In an extensive study, researchers from the University of Montana, University of California - Santa Cruz, and the University of California - Davis have shown that a top predator strongly affected plants and animals at the bottom of an island food web by eating organisms that transport nutrients between ecosystems. "An introduced predator alters Aleutian island plant communities by thwarting nutrient subsidies," is published in the February issue of Ecological Monographs.
