Researchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive "rhamnolipids," and effectively help degrade polycyclic aromatic hydrocarbons

While an out-of-control gusher deep in the Gulf of Mexico fouls beaches and chokes marshland habitat, another threat could be growing below the oil-slicked surface

Researchers have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North

Was Tyrannosaurus rex cold-blooded? Did birds regulate their body temperatures before or after they began to grow feathers? Why would evolution favor warm-bloodedness when it has such a high energy cost?

One way that geologists try to decipher how cells functioned as far back as 3 billion years is by studying modern microbial mats, or gooey layers of nutrient-exchanging bacteria that grow mostly on moist surfaces and collect dirt and minerals that crystal

Doctors could one day diagnose food allergies with a simple blood test that would be faster and more reliable than current tests

How can a tiny spider body contain material for several decimeters of gossamer silk, and what governs the conversion to thread? Researchers at the Swedish University of Agricultural Sciences (SLU) in Sweden can now explain this process

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has used x-ray diffraction microscopy to make images of whole yeast cells, achieving the highest resolution -- 11 to 13 nanometers (billionths of a meter) -- ever obtaine

Researchers in the Department of Biochemistry and Molecular Biology at Thomas Jefferson University have found that the level of a single protein in the tiny roundworm C. elegans determines how long it lives

Researchers have discovered that mice -- and probably humans and other mammals as well -- produce their own morphine in their bodies
