Forsyth scientists suggest linkages between obesity and oral bacterial infection
A scientific team from The Forsyth Institute has discovered new links between certain oral bacteria and obesity. In a recent study, the researchers demonstrated that the salivary bacterial composition of overweight women differs from non-overweight women. This preliminary work may provide clues to...
Fossils suggest earlier land-water transition of tetrapod
DURHAM, N.C. -- New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber.
Both extinct species, known as Ichthyostega and Acanthostega, lived an estimated 360-37...
Genes from tiny marine algae suggest unsuspected avenues for new research
MOSS LANDING, CA By sequencing the DNA of two tiny marine algae, a team of scientists has opened up a myriad of possibilities for new research in algal physiology, plant biology, and marine ecology. The project was led by Alexandra Worden at the Monterey Bay Aquarium Research Institute (MBARI) an...
New data suggest 'jumping genes' play a significant role in gene regulatory networks
CHICAGO, IL--Research performed in the Center for Biomolecular Science & Engineering (CBSE) at the University of California, Santa Cruz, suggests that mobile repetitive elements--also known as transposons or "jumping genes"--do indeed affect the evolution of gene regulatory networks.
Atomic-resolution views suggest function of enzyme that regulates light-detecting signals in eye
An atomic-resolution view of an enzyme found only in the eye has given researchers at the University of Washington (UW) clues about how this enzyme, essential to vision, is activated. The enzyme, phosphodiesterase 6 (PDE6), is central to the way light entering the retina is converted into a cascad...
Models of eel cells suggest electrifying possibilities

Little teeth suggest big jump in primate timeline
DURHAM, N.C. -- Tiny fossilized teeth excavated from an Indian open-pit coal mine could be the oldest Asian remains ever found of anthropoids, the primate lineage of today's monkeys, apes and humans, say researchers from Duke University and the Indian Institute of Technology.

These findings support concurrent ...
Features of replication suggest viruses have common themes, vulnerabilities

Threatened birds may be rarer than geographic range maps suggest

Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety

Molecular research suggest shift needed in how some drugs are created
The first close-up look at a pro-inflammatory signaling molecule involved in immune response in mammals suggests that researchers "should rethink what they are doing" in creating drugs based on a fruit-fly model, scientists say.

Why do aneurysms form? New studies suggest leading role for white blood cells
Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.
But despite the deadly ...
New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines
New insights by Duke University Medical Center researchers as to how HIV evades the human immune system may offer a new approach for developing HIV vaccines. The findings suggest
