Sniffing Dog Provides Cost-Effective Contamination Detection
America's only dog that's trained to sniff mercury is able to detect as little as a half-gram, and is faster and cheaper than traditional lab analysis. Dogs' olfactory membranes are larger and 44 ... > more -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > more -
Are Bioluminescent Bacteria Behind Milky Seas Legend?
For centuries, sailors in the Indian Ocean have told stories of seas glowing with a dim, white light at night. Satellite images have now confirmed the appearance of what seem to be bioluminescent ... > more -
Newly Sequenced Genome Could Shed Light on Human Diseases
Molecular biologists have completely sequenced the first dog genome. Understanding how genetics plays a role in canine diseases could lead to new treatments for diseases shared by humans, such as ... > more -
Entomologists Train Insects to Act Like Sniffing Dogs
If rewarded with sugary water, wasps can be trained in minutes to follow specific smells. The olfactory sensors in their antennae can sense chemicals in the air in concentrations as tiny as a few ... > more -
Horticulture Engineers Take Years to Carefully Grow Bulbs
Of the 1,700 varieties of tulips, about 80 percent come from Holland, which exports more than $700 million's worth of tulips per year. Tulip bulbs take up to five years to fully form, and require ... > 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
