Microbiologists and Astrobiologists Help Kids Discover New Species
Extremophiles are microbes that have adapted to extreme environments, such as Utah's Great Salt Lake. But new microorganisms can be found in everyday places, and scientists are showing school kids ... > more -
Environmental Toxicologists Link Household Bacteria to Asthma
Scientists have found that chemicals called endotoxins can inflame airways and trigger asthma. Endotoxins are shed by bacteria in household dust. Experts say better home hygiene, washing bed linens ... > more -
Researchers Apply DNA Biology to Vaccination Technique
Spraying viral genes directly through the skin is a new technique that turns infinitesimal amounts of DNA into an effective vaccine. If approved for use in humans, the new procedure could save lives ... > more -
Microbiologists Find Soap and Water Best for Washing Hands, Removing Germs
Microbiologists tested 14 hand-hygiene agents -- everything from soap and alcohol rubs to plain old tap water -- against hardy bacteria and viruses applied to the hands of 62 volunteers. The study ... > more -
In Hospitals, Air Ducts with Silver-Based Coating Stay Germ-Free
Preventing hospital infections -- from such stubborn bugs as Staphylococcus aureus -- could get a little easier with a new non-toxic, silver-based material. Used in coating, it helps keep hospital ... > more -
Plant Scientists Graft Apple Trees to Select Disease-Resistant Traits
Grafting -- an ancient way of cloning plants -- enables plant scientists to create new varieties of apples. The selected genetic traits allow trees to resist pests with less pesticides, and to make ... > more -
Insect Ecologist Spearheads Creation of Oases for Endangered Butterflies
Waystations for monarch butterflies are sprouting up around the country. With milkweed plants and flowers such as zinnias that produce lots of nectar, these gardens will provide oases for the ... > more -
Chemist's Glue Borrows Unique Amino Acid from Mollusk
Chemists combined an exotic form of an amino acid -- used by mussels to stick to rocks -- with soy flour to make a new, high-strength adhesive. The new glue helps in manufacturing natural-looking ... > more -
Materials Engineers Turn to Ferocious Fish for Nonstick Ship Coating
Researchers are using shark skin as a model for creating new coatings that prevent adhesion of algae and barnacles to boats. The new coating is modeled after sharks' placoid scales, which have a ... > more
