With support from the National Science Foundation, computer scientist Shwetak Patel and his team at the University of Washington are developing new sensing systems to empower people to make better-informed decisions for themselves and their homes. Patel's initial interest was in providing the most detailed information yet for consumers about their energy and water consumption, and most of that technology has already been transferred to the marketplace. Part of the "Science Nation" series.
With support from the National Science Foundation, device engineer Jason Heikenfeld of the University of Cincinnati and a multidisciplinary team are developing new technologies to take sweat biosensors to the next level. Their wearable patches allow tiny amounts of sweat to be captured and analyzed quickly and accurately with strong correlation to blood data. The researchers envision a day when data from continuous sweat monitoring will be an essential tool in health care, like blood tests. Part of the "Science Nation" series.
Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
Inside a cylinder that is about the size of a roll of paper towels lives a circuit board filled with sensors. It's called a dropsonde, or “sonde” for short. As the sonde falls through the air after being dropped for an airplane, its sensors gather data about the atmosphere. Dropsondes have a huge impact on understanding hurricanes and the ability to predict hurricanes. Part of the National Science Foundation Series “Science Nation.”
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 support from the National Science Foundation, Vanderbilt University biologist Laurence Zwiebel researched which mosquito genes are linked to odor reception. He discovered a separate odor sensor on a mosquito's antennae. According to Zwiebel, mosquitoes use odor sensors to sniff out humans and other tasty animals to bite. The new insect repellent compound takes advantage of his discovery by overwhelming the mosquito’s odor sensors to the point that they can't smell anything else and get scared away.
A shark attack survivor now knows what it feels like to be part bionic man. 23-year-old amputee Craig Hutto has volunteered to help test a state-of-the-art prosthetic leg with powered knee and ankle joints. With 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 motor, a battery, and computer technology. Sensors monitor the user's motion and microprocessors figure out what the person is trying to do. Goldfarb says the powered leg reduces the lag time between a real leg and a prosthetic one. Hutto confirms that the powered prosthetic is much better at anticipating his next move.
Volcanologist Michael Manga and his students study geysers in Chile and Yellowstone National Park. They thread sensors and cameras into the boiling water in an effort to come up with an explanation for why geysers erupt periodically.
A hurricane hunter is a pilot that flies an airplane into the middle of a hurricane. They gather data on temperature, humidity, and air pressure. This data is critical for forecasting the intensity and path of hurricanes. Part of the "NOAA Ocean Today" series.
Presents sensory receptors that depend on contact with the immediate world: taste buds, touch sensors, and olfactory cells. These receptors lie in the skin, the largest organ of the body, which also senses heat, pain, and pressure. Re-creates the complex world of the skin through realistic models and photographs.
Offers a look at what kind of information satellites provide about our world. Satellite imagery has multiple uses: showing crops and pests, monitoring weather in all its forms, following forest fires and air pollutants, and more. Imagery notes climate changes, the ozone layer, and temperature of many things--all designed to predict and protect. These sensors present unusual windows to our world.
Shows how the cerebellum coordinates muscle activity and how position sensors in the muscles and joints and the balancing mechanism of the inner ear function. The motions of a water-skier show the physical, interconnected structure of muscles, joints, and organs. The role of joints is explained, and a look at the interior of a human knee shows clearly how lubricating fluid is produced.
A new generation of smaller, highly capable radar systems in the Dallas/Fort Worth area is able to track with more accuracy the location of tornadoes and other severe weather conditions. These new systems are spaced much closer together than current radar sensors, and the closer proximity is part of the reason the new systems can catch a tornado that could be missed by current radar.

Antarctica' largest ice shelf is giving off some spooky vibes. With the help of extremely sensitive seismic sensors, scientists confirmed that winds blowing across the snow dunes of the ice shelf cause the surface to rumble. Other segments include the oldest clue of animal life, volcanic super-eruptions, and contraction and expansion of the tropical belt.

Carnegie Mellon University Computer Scientist and Electrical Engineer, Anthony Rowe, can always keep an eye on his home, even when he’s traveled to another time zone. That’s because he’s rigged his home with sensors he invented with support from the National Science Foundation. Now all he needs is a laptop to help him keep track of all his appliances – whether they are on or off and how much energy they’re using.
Locked-in syndrome is a condition in which people with normal cognitive brain activity suffer severe paralysis, often from injuries or an illness such as Lou Gehrig’s disease. Boston University neuroscientist Frank Guenther conducts research on how brain regions interact, with the hope of melding mind and machine, and ultimately making life much better for people with locked-in syndrome.
The University of Washington is advancing research into deep brain stimulation, which is used to treat people with essential tremor, Parkinson's disease, and other conditions. At the Center for Neurotechnology, a team is designing and testing upgrades for devices to make them smarter and less intrusive. Along with enhanced brain sensors, new control algorithms, and machine-learning techniques to improve device performance, the team is ensuring the design meets the day-to-day usability needs of patients.

A research team has found that sweat is better than saliva and tears for noninvasive testing because it provides information much the same as blood. The team has developed Band-Aid-like sensors to collect health information from sweat. Other segments include the evidence that temperature determines sex for some animals, new methods for delaying ice and frost, and a historic discovery of 500 million-year-old fossils.

For more than a decade—in the most inhospitable place on Earth-- scientists have been building an observatory to search for a “ghost.” The IceCube Neutrino Observatory is a massive telescope embedded in the Antarctic ice near the South Pole. Its aim: to search for elusive subatomic particles called neutrinos that have made their way to earth from distant cosmic events like supernovas and black holes. Neutrino research is pushing the astrophysics envelope, and should provide answers to key questions about dark energy and dark matter.
