Science Nation - Unraveling the Mysteries of Tornadoes

submitted by: nsf
Greg Carbin knows a lot about severe weather. He's a meteorologist at the storm prediction center, located just south of Oklahoma City in Norman, Okla. In a quiet room on the second floor of the National Weather Service building, meteorologists are standing guard twenty-four hours a day, seven days a week, keeping an eye on weather systems that could unleash violent storms and tornadoes. The meteorologists issue storm watches as needed. For this and more Science Nation, go to...

Science Nation - Gaze into my Eyes

submitted by: nsf
When it comes to communication, sometimes it's our body language that says the most - especially when it comes to our eyes. "It turns out that gaze tells us all sorts of things about attention, about mental states, about roles in conversations," says Bilge Mutlu, a computer scientist at the University of Wisconsin-Madison. Mutlu knows a thing or two about the psychology of body language. He bills himself as a human-computer interaction specialist. Support from the National Science Foundation...

Science Nation - Nosing Out Mosquitoes

submitted by: nsf
Vanderbilt University researchers say they're working to unleash an insect repellent on mosquitoes that's more powerful than DEET. The discovery could one day be effective in reducing the spread of mosquito-borne diseases, such as malaria. It's based on a mosquito's sense of smell. With early support from the National Science Foundation, Vanderbilt University biologist Laurence Zwiebel researched which mosquito genes are linked to odor reception. Since then, he's discovered a separate odor...

Science Nation - How Does Your Garden Grow?

submitted by: nsf
At first, the back room of plant physiologist Edgar Spalding's lab at the University of Wisconsin-Madison might be mistaken for an alien space ship set straight out of a Hollywood movie. It's a room bathed in low-red light with camera lenses pointing at strange looking entities encased in Petri dishes. A closer inspection reveals the Petri dishes contain nothing alien at all, but rather very down-to-earth corn seedlings. They're grown in red light for optimal growth. They're just one of...

Science Nation - Africa's Drinking Water

submitted by: nsf
Access to safe drinking water is a global problem for nearly a billion people. For approximately 200 million people, many in Africa, high levels of naturally occurring fluoride in the water cause disfiguring and debilitating dental and skeletal disease. University of Oklahoma (OU) environmental scientist Laura Brunson is back from Ethiopia where, with support from the National Science Foundation, she's developing fluoride filtering devices that use inexpensive materials readily available...

Science Nation - Skin Mounted Electronics

submitted by: nsf
John Rogers and his team at the University of Illinois, Champaign-Urbana have come up with a way to monitor the body electronically that really sticks. They have developed a small, flexible circuit device that sticks comfortably to the skin and is artfully camouflaged as a temporary tattoo. It can read a patient's brainwaves, heart rate and muscle activity while they are going about their normal activity, making it possible to cut back on visits to the doctor's office. Rogers envisions one...

Science Nation - Bionic Leg

submitted by: nsf
A shark attack survivor now knows what it feels like to be part bionic man. 23-year-old amputee Craig Hutto has volunteered to play guinea pig, testing a state-of-the-art prosthetic leg with powered knee and ankle joints. With early support from the National Science Foundation and continued support from the National Institutes of Health, Vanderbilt University mechanical engineer Michael Goldfarb has spent several years developing the leg, which operates with special sensors, an electric...

Science Nation - Early Cancer Screening

submitted by: nsf
With few early symptoms, ovarian cancer — like many cancers — can be hard to detect without invasive and expensive procedures. "Early detection is absolutely not only key but probably the only way for us to win the war on cancer," says Vadim Backman who is a biomedical engineer at Northwestern University in Evanston, Ill. With support from the National Science Foundation, in part funded through the American Recovery and Reinvestment Act of 2009 (ARRA), Backman's research is shedding...
