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 -
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 -
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 -
Entomologists Design Environmentally-Friendly Lawns, Golf Courses
The PGA Golf course at San Francisco's Harding Park is an environmental model, using fewer pesticides than any other PGA course in the country. Taking a cue from entomologists and other scientists, ... > 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
