Hydrogen and methane provide raw energy for life at 'Lost City'

...st City, Kelley says she's 100 percent sure others exist because there are so many other places mantle rock has been thrust up through the seafloor, exposing it to seawater and serpentinization. Even more such rocks were present on early Earth, Kelley says. "We don't, in most places, have access to early...

Stealth Worms May Improve Insect Pest Control

...ns in biology." Given the number of nematodes that exist in the world, the possibilities for discovery are immense. "The whole nematode phylum is estimated to have 500,000 to a million species. About 25,000 species have been identified so far," Stock says. ...

Breakthrough isolating embryo-quality stem cells from blood

...cientists have known for some time that stem cells exist in adult human blood and certain other tissues. However the only reliable way to separate them involved marking the cells with a chemical dye, rendering them useless for medical purposes. Professor Käs' technique for the first time uses a physical ch...

Gladstone investigators discover how resting T cells avoid HIV infection

...ghly 95 percent of CD4 T cells in the blood stream exist in a resting, inactive state, awaiting the appearance of their specific antigen. When they detect its presence, they spring into action -- growing and dividing, releasing cytokines (proteins that the immune system uses to communicate between cells) a...

Study uncovers bacteria's worst enemy

...dionuclides, organic chemicals and metal regularly exist at many nuclear sites. Based on the results of this study, if bioremediation is to be effective at these types of sites, the operative microorganisms must be able to grow, function and do better than other bacteria in the presence of all kinds of con...

Same-Sex Mating Discovered in a Toxic Fungus

...lso of Duke. "Organisms, including fungi, usually exist in an approximately one-to-one sex ratio," Lin said. "Yet in Cryptococcus neoformans, one mating type predominates, leaving them with apparently few chances to mate. It's been a mystery." In 1996, another group discovered that those alpha isolates c...

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed
