New material could 'revolutionize' treatment of broken bones
A new material that could speed the healing of severely fractured bones and reduce the need for invasive surgery was described here today at the 220th national meeting of the American Chemical Society.

Preserving museum treasures from Old Masters to spacesuits
A special daylong symposium at the 220th national meeting of the American Chemical Society, the world's largest scientific society, will focus on preserving museum treasures from Old Masters to astronauts' spacesuits.

Put a polymer in your tank
A gasoline additive that may be able to dramatically increase mileage and engine power with less pollution was described at the 220th national meeting of the American Chemical Society.

Lupus patients are in remission two years after high-dose chemotherapy and stem-cell transplantation
Northwestern University researchers evaluated the safety and efficacy of high-dose immune suppression and stem-cell transplantation in patients with lupus.

Farms and livestock leave their mark on the Chesapeake Bay
Pesticides, agricultural runoff and animal by-products are affecting fish, frogs and the overall state of the Chesapeake Bay.

NASA awards study contracts for Space Station contingency cargo launch services
NASA has awarded four small businesses 90-day contracts totaling $902,000 to develop concepts and requirements to provide access to the International Space Station on emerging launch systems.

New process improves potency, uses of grape seed extracts
Researchers at Virginia Tech and the University of Cadiz in Spain have developed a method using carbon dioxide instead of organic solvents to extract many of the antioxidants from grape seeds.

Fiber optic laser could track changes in Earth's ozone layer
Johns Hopkins and NASA engineers will collaborate on developing a space-based fiber optic laser system to track atmospheric changes caused by global warming.

Chemists and curators join forces to save Old Masters
It's enough to make the 'Mona Lisa' stop smiling. In an effort to preserve old paintings, collectors and curators unknowingly used untested and risky techniques that are causing the polymers forming their paints to fall apart.

Chemical scissors may fine-tune nerve cell migration
HHMI researchers have shown that nerve cells may actually use a chemical scissors to snip off a portion of an axon guidance receptor in order to ensure proper navigation in the central and peripheral nervous system.

New model suggest how prions take shape
HHMI researchers have identified a new mechanism by which the infective proteins in yeast called prions replicate their structures.

Deadly for bacteria, great for consumers
Electricity and water can be fatal. But that could be good news for consumers now that researchers have shown the deadly combination also kills bacteria like E. coli, salmonella and listeria on foods and food utensils.

Supplements that target fat loss … metals that protect themselves …
A dietary supplement that could help people lose fat and keep it off, a kinder, gentler aspirin and a new environmentally friendly gasoline additive are just a few of the research topics being presented at the national meeting of the American Chemical Society in Washington from Aug.

Canine leishmaniasis cases are confirmed in 21 states
Results of DNA and blood tests by scientists at North Carolina State University and the CDC have confirmed cases of visceral canine leishmaniasis - a rare, often fatal tropical disease that can be transmitted to humans and other animals - in 21 US states and southern Canada. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
