New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
Study: Sea stars bulk up to beat the heat
A new study finds that a species of sea star stays cool using a strategy never before seen in the animal kingdom. The sea stars soak up cold sea water into their bodies during high tide as buffer against potentially damaging temperatures brought about by direct sunlight at low tide. view more (2009-11-18)
Sponges recycle carbon to give life to coral reefs

Training clinicians helps reduce rates of early childhood cavities
Researchers at Boston University School of Medicine (BUSM) have found that pediatricians provided with the proper communication, educational and information technology tools and training could reduce the rates of children developing early childhood caries (ECC) or cavities by 77 percent. view more (2009-09-30)
American-Made SRF Cavity Makes the Grade
The U.S. Department of Energy's (DOE's) Thomas Jefferson National Accelerator Facility marked a step forward in the field of advanced particle accelerator technology with the successful test of the first U.S.-built superconducting radiofrequency (SRF) niobium cavity to meet the exacting specifications of the proposed International Linear Collider... view more...

Sugar substitute appears to prevent early-childhood cavities
Children given an oral syrup containing the naturally occurring sweetener xylitol may be less likely to develop decay in their baby teeth. view more (2009-07-07)
How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae). view more (2009-06-25)
New stem cell research unlocks unknown therapies
"Stem cell research and regenerative medicine are in an extremely exciting phase right now. We are gaining knowledge very fast and many companies are being formed and are starting clinical trials in different areas," says Dr Jonas Frisén. view more (2009-05-22)
Endoscopic surgery effectively relieves sinusitis symptoms; large pooled study
Endoscopic sinus surgery can significantly relieve symptoms of chronic rhinosinusitis - inflammation of the sinus cavities - according to a research team, led by a Georgetown physician, which conducted the first large-scale analysis of surgical outcomes from the procedure. view more (2009-05-01)
Does the stress of being a parent lead to decay in children's teeth?
A team of scientists from The Ohio State University has examined the stress levels of parents whose young children either had no cavities or so many cavities that the children had receive anesthesia before undergoing dental treatment. view more (2009-04-06)
Research synthesis shines light on several management options after fires in diverse ecosystems
No single decision-support system exists for selecting alternatives for postfire management. That thesis is what a recently released report on management after fire hinges upon. The publication, Effects of Timber Harvest Following Wildfire in Western North America, tells us that the type of forest landscape determines the ways fire and logging may... view more...

Plasmonic Whispering Gallery Microcavity Paves the Way to Future Nanolasers
The principle behind whispering galleries - where words spoken softly beneath a domed ceiling or in a vault can be clearly heard on the opposite side of the chamber - has been used to achieve what could prove to be a significant breakthrough in the miniaturization of lasers. Ultrasmall lasers, i.e., nanoscale, promise a wide variety of intriguing... view more... (2009-01-26)
Male Dinosaurs May Have Been Babysitters
Those ferocious Hollywood meat-eating dinosaurs you're used to seeing in the movies very possibly had a much softer side: the males might even have been sort of prehistoric babysitters, according to a far-flung study conducted by a Texas A&M University researcher. view more (2008-12-19)
Micro honeycomb materials enable new physics in aicraft sound reduction
Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and landing. It can also make aircraft interiors excessively loud. view more (2008-09-30)
