Poisoning :: Mercury contamination identified in eastern North America
Mercury released into the atmosphere is concentrated in aquatic food chains, giving rise to harmful levels in biota in sensitive regions.

Cholesterol :: Sugars in liver found to clear fats from the bloodstream
In work with mice, researchers at the University of California, San Diego, School of Medicine discovered a factor that could be responsible for many unexplained cases of elevated triglyceride levels.
Influenza :: New details on how the immune system recognizes influenza
Drawing upon a massive database established with funds from the National Institute of Allergy and Infectious Diseases (NIAID), one of the National Institutes of Health (NIH), scientists have completed the most comprehensive analysis to date of published influenza A virus epitopes–the critical sites on the virus that are recognized by the immune system.
DNA :: Repair Mechanism of DNA Double-Strand Breaks
A team of Mayo Clinic researchers has uncovered a key step in the molecular pathway of repairing DNA double-strand breaks. The findings are published in the current edition of the journal Cell.
Cancer :: Body composition controls cancer risks
Scientists have long thought that limiting the calories a person consumes can prevent, or at least slow the progression of certain cancers. But research at UAB (University of Alabama at Birmingham) using mice suggests that body composition ? whether a person is lean or obese ? actually is key to reducing cancer risks.
Gene :: Genome stability and epithelial carcinogenesis
Dr. Leonard Zon and colleagues at The Children’s Hospital (Boston) have identified a mutated gene in zebrafish that increases susceptibility to epithelial cancers.
RNA :: MicroRNAs, alternative splicing and the muscle proteome
As reported in the January 1 issue of G&D, a UCLA research team led by Dr. Douglas Black has shown how microRNAs regulate alternative splicing during muscle development.
HIV :: Spy link in Libya’s HIV case – Gaddafi
“Libyan leader Muammar Gaddafi expressed his doubts suggesting spy link in HIV case” a Reuters report from Tripoli revealed. Gaddafi defended the court’s decision to sentence five Bulgarian nurses and a Palestinian doctor to death for infecting more than 400 children with HIV.
Stroke :: New treatments prevent brain injury hours after stroke
Two novel treatments — a basic compound found in every cell in the body and an extract of green tea — may prevent brain damage caused from stroke, according to two studies in rats led by a researcher at the San Francisco VA Medical Center.
Influenza :: Molecular anatomy of influenza virus detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes influenza.
