Tornadoes claim hundreds of lives and cause billions of dollars in damages in the United States. With support from the National Science Foundation, computer scientist Amy McGovern at the University of Oklahoma is working to find answers to key questions about tornado formation. While video from storm chasers and data from Doppler radar can help meteorologists understand some aspects of tornadoes, McGovern uses supercomputers to find patterns in very large datasets. She also works with weather experts to help her sort out the information in the simulations. McGovern’s ultimate goal is to come up with reliable tornado forecasting system.
The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
When the water along Rhode Island’s Narragansett Bay is thick and green, it may be a bad day for a swim, but it’s an excellent day for University of Rhode Island marine ecologist Carol Thornber. Thornber and her team are conducting a long-term study of the impacts of climate change on macroalgae, or seaweed, and algal blooms. She is investigating how the blooms affect fish stocks and oyster beds as well as how nutrients in the water from sewage treatment and agricultural runoff can feed the blooms and make them larger.

Mobile computing is accelerating beyond the smartphone era. Today, people wear smart glasses, smart watches, and fitness devices, and they carry smartphones, tablets, and laptops. In a decade, the very same people are likely to wear or carry tens of wireless devices and interact with the Internet and computing infrastructure in markedly different ways. Computer scientist Xia Zhou is working to make sure there are no traffic jams with the increased demand. With support from the National Science Foundation, Zhou and her team at Dartmouth College are developing ways to encode and transmit all that data faster and more securely. Part of the "Science Nation" series.
Scientists at NASA’s Jet Propulsion Laboratory give tips on how to come up with a unique idea for a science fair project. In this segment, they encourage students to look around and ask questions about what they see. This can include observations about patterns, shapes, and behaviors. Part of the “How to Do a Science Fair Project” series.
Welcome to Barrow, Alaska, where a team of marine ecologists gears up to hit the sea ice that is actually teaming with marine life. With support from the National Science Foundation (NSF), Craig Aumack of Columbia University and a team have come here to investigate how algae in the sea ice contributes to the underlying marine ecosystems, and which marine organisms depend on the algae for nutrition. Part of the National Science Foundation Series “Science Nation.”
While Earth's weather reports center on precipitation, temperature, wind direction, and humidity, space weather forecasts attempt to predict activity that occurs on the sun. Scientists also study how the weather on the sun will affect Earth. At the University of Michigan a team studies solar storms as they form and then barrel off the sun. Sometimes these storms hit the Earth with damaging force. Space weather has the potential to interfere with everything from satellite communications to electrical power. This team is aiming for a five-day forecast capability to give government, private industry, satellite operators, and power grid companies more time to take necessary action to protect critical infrastructure.

Understanding what happens at the epicenter of an earthquake, as the tectonic plates beneath the earth shift and the earth shakes, could help better predict when and where the next big one will hit. For the past six years scientists from a number of institutions have joined in a project called San Andreas Fault Observatory at Depth, or SAFOD. They have drilled to the core of the San Andreas Fault, near Parkfield California, down to a specific area along the fault known to experience a number of small earthquakes every year. By retrieving and studying core rock samples from that site, geologists Chris Marone and Brett Carpenter and hydrogeologist Demian Saffer are getting a better understanding of the types of rocks involved in major quakes, versus the rocks present at more forgiving ones.
Hurricane Sandy was the deadliest of the 2012 hurricane season and was the second costliest hurricane in U.S. history. University of Washington civil engineer Dorothy Reed and her team received a grant from the National Science Foundation to study how Hurricane Sandy affected the infrastructure of the New York Metropolitan area, including the power and transit systems. Reed and her team area creating highly detailed maps to construct a comprehensive street-by-street view of Sandy’s devastation.
What determines how many species live in a given place? Or how many individuals of the species can live somewhere? The research that provided answers to these questions was set in motion by the key experiments of ecologists Robert Paine and James Estes. Their research demonstrates just how fundamental keystone species and trophic cascades are in understanding ecology.
MIT professor Tom Levenson retells the amazing history of planet Vulcan. It is a story that reveals how the power of an idea can shape the currents of thought, and sometimes, lead researchers down the wrong path. Meanwhile, Harvard experimental particle physicist Melissa Franklin reflects on how the lessons from Vulcan apply to research today and how, in the end, science manages to get things right. Part of the "Think Like a Scientist" series.
Philanthropist Greg Carr describes his work reviving a national park in Mozambique, and his partnership with scientists at Princeton University. Biologist Rob Pringle, who conducts research in Gorongosa, explains what it means to think like a scientist in conservation biology. Part of the “Think Like a Scientist” series.
Watch the story of how gene therapy restored the sight of a nearly-blind young patient. Told from the perspective of two researchers who spent over 25 years working to develop this breakthrough technology, this short film chronicles their successes and challenges, and illustrates how the method works to treat inherited conditions.
Can damage to coral reefs be repaired? Two researchers are looking for solutions to this question. Dr. Steve Palumbi conducts research on the corals around Ofu Island in American Samoa. He is trying to determine why these native corals can withstand ocean temperatures that, in other coral species, would lead to coral bleaching. Along with graduate student Megan Morikawa, Palumbi is testing whether these heat-resistant corals can be transplanted to reefs that have been damaged or destroyed.
Journalist Greg O'Brien reveals his struggle living with Alzheimer's disease, including the effects on his family. Harvard scientist, Rudy Tanzi, explains the mechanism by which this disease robs the identities of those affected. Tanzi also reveals current research into the treatment of the disease. Part of the “Think Like a Scientist” series.
Fruit bats carry the Nipah virus, which can be transmitted to humans and cause severe disease. In Bangladesh, the virus causes a disease outbreak almost every year. Dr. Jon Epstein of the EcoHealth Alliance explains the evidence that revealed bats are the natural reservoir of the virus. Their research also shows the route of transmission to humans. Dr. Epstein and collaborators in Bangladesh are now monitoring bat populations throughout the country for the presence of the virus to identify human populations that might be at risk of transmission.
Anole lizards are highly territorial and typically stick close to their home tree. So, what happens when a team of researchers carries them far away into the forest? Will they find their way back? Dr. Manuel Leal and colleagues designed an experiment to find out. They displaced the lizards from their home territories and then tracked their movements using radio transmitters. Most of the lizards were able to orient themselves and head in the right direction, with some making a beeline back to their original tree in less than 24 hours.
At the University of Montana, Ken Dial researches the mechanics of bird flight. He studies young birds that are learning to fly, and he hopes his experiments will provide new evidence for how flight might have evolved.
