Study in Nature shows wide variation in the collection of bacteria harbored by healthy adult.

The Environmental Protection Agency’s (EPA’s) recommendations for treating water after a natural disaster or other emergencies call for more chlorine bleach than is necessary to kill disease-causing pathogens and are often impractical to carry out, a new study has found.

Scientists at The University of Texas at Austin have discovered that a protein produced by the influenza A virus helps it outwit one of our body's natural defense mechanisms. That makes the protein a potentially good target for antiviral drugs directed against the influenza A virus.

On April 10, the U.S. Environmental Protection Agency (EPA) announced research grants to Arizona State University and the University of California, Santa Barbara to better understand the impacts of chemicals and nanomaterials throughout their life cycle—from design, manufacture, use and disposal.

In a new study, researchers from North Carolina State University, UNC-Chapel Hill and other institutions have taken the first steps toward creating a roadmap that may help scientists narrow down the genetic cause of numerous diseases. Their work also sheds new light on how heredity and environment can affect gene expression.

Flu epidemics cause up to half a million deaths worldwide each year, and emerging strains continually threaten to spread to humans and cause even deadlier pandemics. A study by McGill University professor Maziar Divangahi published by Cell Press on April 10 in the journal Immunity reveals that a drug that inhibits a molecule called prostaglandin E2 (PGE2) increases survival rates in mice infected with a lethal dose of the H1N1 flu virus. The findings pave the way for an urgently needed therapy that is highly effective against the flu virus and potentially other viral infections.

Some nanoparticles commonly added to consumer products can significantly damage DNA.

Diagnostic effectiveness is driving the accelerated acceptance of Stanbio Laboratory’s Beta Hydroxybutyrate LiquiColor® reagent in U.S. hospital chemistry laboratories. The assay is used primarily for determining both the presence and degree of ketosis in suspected diabetic ketoacidosis cases.

The potential health benefits of dark chocolate keep piling up, and scientists are now homing in on what ingredients in chocolate might help prevent obesity, as well as type-2 diabetes.

A five-year, $10 million Specialized Research Center grant from the National Institutes of Health (NIH) will help scientists from across Cornell University's campus tackle the roots of reproductive issues and train the next generation of reproduction scientists.

A research team at the Georgia Tech Research Institute (GTRI) has developed a small electronic sensing device that can alert users wirelessly to the presence of chemical vapors in the atmosphere. The technology, which could be manufactured using familiar aerosol-jet printing techniques, is aimed at myriad applications in military, commercial, environmental, healthcare and other areas.

Does the widespread and still proliferating use of antimicrobial household products cause more harm than good to consumers and the environment? Evidence compiled in a new feature article published in the journal Environmental Science & Technology (ES&T) by Arizona State University professor Rolf Halden shows that decades of widespread use of antimicrobials has left consumers with no measurable benefits.
