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 -
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 -
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

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 -
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 -
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
