Veterinarians Show Consoling Dogs Does Not Relieve Their Panic
A new study shows that dogs can get very upset during thunderstorms, whether or not their owner holds them. The study measured the stress hormone cortisol to be up to three times normal levels while ... > more -
Electrical Engineers Monitor Environment with Robotic Sensors
Fleets of robotic sensors, networking through thin cables, can track environmental changes such as biogeochemical cycles or loss of biodiversity, helping to manage wild lands. The technology is the ... > more -
Biochemists Create Microbicidal Coating to Fight Hospital Infections
New bandages with microbicidal coating kill the most harmful bacteria on contact. The coating is washable and can also be used on hospital gowns and bed sheets, which will help reduce the risk of ... > 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 -
Ecologists Deploy Wireless Sensors for Early Detection of Wildfires
New fire-sensing devices can spot a fire in its earliest stages, up to six miles away, and they can relay the information to emergency responders through a computer network and even automatically ... > more -
Soil Chemists Plant Ferns to Soak Up Backyard Poisons
Planting ferns can be a cheaper, greener way to soak up poisons such as arsenic from the soil. Ferns absorb arsenic through their roots and store it in their leaves, which can then be cut off. ... > more -

Biologist, Computer Scientist Make 3D Anatomy Images Available Online
Frog biology is especially noteworthy because of the amphibians' sensitivity to pollution, which often flags previously unknown environmental problems. Science labs and classrooms around the world ... > 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
