Ancient Oak Trees Help Reduce Global Warming (June 28, 2008) -- The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers have discovered that nature has been lending a hand. They have discovered that trees submerged in freshwater aquatic systems store carbon for thousands of years, a significantly longer period of time than trees that fall in a forest, thus keeping carbon out of the atmosphere. ... > full story
Device Blocking Stomach Nerve Signals Shows Promise In Obesity (June 28, 2008) -- A new implantable medical device shows promise as a reversible and less extreme alternative to existing bariatric surgeries, according to new findings. ... > full story
Blue Light Used To Harden Tooth Fillings Stunts Tumor Growth (June 28, 2008) -- A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say. ... > full story
Safer, More Efficient Medication For Hepatitis B Treatment Found (June 28, 2008) -- Patients with hepatitis B who did not respond to lamivudine therapy had a better virological response after switching to entecavir for a year. ... > full story
Algae From The Ocean May Offer A Sustainable Energy Source Of The Future (June 28, 2008) -- New research could help with the large-scale cultivation and manufacturing of oil-rich algae in oceans for biofuel. Algae are a diverse and simple group of organisms that live in or near water. Certain algal species are high in oil content that could be converted into such fuels as biodiesel, according researchers. Algae also have several environmentally-friendly advantages over corn or other plants used for biofuels, including not needing soil or fresh water to grow. ... > full story
Personalizing Medicine: New Research Shows Potential Of Targeted Therapies For Cancer (June 28, 2008) -- A new study shows the potential to pre-target the treatment of cancer cells -- bringing personalized medicine one step closer from the laboratory to patients. By combining new molecular imaging techniques with targeted therapy, pre-targeting offers cancer patients a more individualized treatment that can increase the effectiveness of therapies and minimize discomfort experienced during treatment. ... > full story
Quantum Computing Breakthrough Arises From Unknown Molecule (June 28, 2008) -- The odd behavior of a molecule in an experimental silicon computer chip has led to a discovery that opens the door to quantum computing in semiconductors. Researchers describe how they have created a new, hybrid molecule in which its quantum state can be intentionally manipulated -- a required step in the building of quantum computers. ... > full story
Starvation Hormone Makes For Small Mice, Study Finds (June 28, 2008) -- Chronically high levels of a recently discovered starvation hormone markedly stunt the growth of mice, reveals a new study. The liver-produced hormone known as FGF21 does so by causing the mice to become resistant to growth hormone. ... > full story
Hidden Facial Cheek Fat Compartments Are Key To Youthful Appearance (June 28, 2008) -- Rejuvenating newly identified fat compartments in the facial cheeks can help reduce the hollowed look of the face as it ages, according to new research by plastic surgeons at UT Southwestern Medical Center. ... > full story
Ronin An Alternate Control For Embryonic Stem Cells (June 28, 2008) -- Like the masterless samurai for whom it is named, the protein Ronin chooses an independent path, maintaining embryonic stem cells in their undifferentiated state and playing essential roles in genesis of embryos and their development, said researchers who reported on this novel cellular regulator in the journal Cell. ... > full story
Ancient Mexican Maize Varieties: Sequencing Of Ancient Corn Landraces To Ensure Genetic Diversity And Resources (June 28, 2008) -- Because of its importance as food, the need to improve yield, and the challenges presented by changing climate, the maize genome of the B73 cultivar is being sequenced. However, because maize has a complex genome and many varieties, the genome sequence from just one variety will not be adequate to represent the diversity of maize worldwide. Mexican scientists are also sequencing and analyzing the genomes of the ancient landraces to recapture the full genetic diversity of this complex and adaptable crop. ... > full story
Binge Drinking Due To 'Copying' Behavior (June 28, 2008) -- The rise in binge drinking in the young is a "fashion phenomenon" where drinkers are copying their associates' behavior, new research carried out in the UK has shown. Researchers say the findings have major implications for Government policy makers charged with tackling the problem, which has longer-term and costly health implications. ... > full story
