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 -
Biologists Help Perfumers Capture New Scents from Nature
To increase perfumers' palette with new scents from flowers, biologists now use a device that captures smells. A plant is covered with a glass dome and vapor is extracted and later analyzed. ... > more -
Scientist Measures Land Used by Lawns
Using census data, satellite images, aerial photographs, and computer simulations, a NASA scientist estimated that turf grass is the single-largest irrigated crop in the United States, three times ... > 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 -
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 -
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
