Exhibit Delves into Science of Taste and Smell
An exhibit at San Francisco's Exploratorium explains the science of cooking and eating, and in particular how we taste food. Our sense of taste comes from a combination of smell receptors in the nose ... > more -
Paleontologists Teach Medical Students About Fossil Tumors
Using medical-physics tools such as CT scans, medical students can learn to recognize a tumor even in a 150-million-year-old dinosaur bone. Paleontologists say the role of disease during evolution ... > more -
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 -
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 -
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 -
Chemists Steal Engineering Tricks from Sponges
Sponges are the homes of colonies of tiny marine animals, and wonders of miniaturized engineering. They employ complex structural arrangements, the strongest glasses known to man, and even ... > 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
