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.”

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.

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.
For centuries, silkworms have been breed to produce strong, fashionable silk threads. Today, the silk industry has joined forces with the biotechnology industry. Researchers are creating genetically modified worms which a produce a protein that aids in clotting blood. Researchers are looking to maybe one day use the protein in medical procedures.
In this episode, researchers discuss the novel applications for a self-healing reverse filter. For example, researchers are studying its application in unsanitary environments. Scientists also ask the question: Is laziness a fruitful strategy for the survival for some species? Researchers are studying the link between metabolic rate and extinction. In the final segment, weather forecasts are predicting that El Niño and La Niña are likely to intensify wildfires and increase drought risk.

Six researchers share 60-second stories about organisms that may be gone, but not forgotten. Researchers and scientists study these stories to get a better understanding of the complexities of life on Earth. Part of the "Shelf Life" series.
This episode highlights recent studies related to beaches and marine life. Researchers have found that seagrass has a strong potential for curbing erosion. Other features include the impact of climate change on right whale movement, expanding efforts to save coral reefs, and the dangers of hurricane storm surge. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
In this episode, researchers operate lab-grown heart cells by remote control, and researchers at UCLA discuss their research on memory. They are conducting experiments with snails. What predictions are scientists making for the future of hurricanes? Based on current models, they will be stronger, slower, and wetter. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
In this episode, researchers are exploring ways to make carbon nanotubes less expensive. The process would use carbon dioxide sucked out of the air. Researchers are also working to identify bacteria and viruses found in ocean spray. Also in this episode, scientists are attempting to design a battery that would charge electronic devices in seconds.

Researchers at New York University are tackling one of the major challenges in agriculture. They are trying to raise healthy plants while minimizing the use of fertilizer and the leaching of fertilizer chemicals into the environment. A team led by scientist Gloria Coruzzi and computer scientist Dennis Shasha is using the latest tools to develop new plant varieties that don't need as much nitrogen to grow. The researchers are also investigating which of the plant's genes control fertilizer uptake. Part of the "Science Nation" series.
Researchers from NOAA's National Marine Mammal Lab track the migrating fur seals to understand where they feed in winter months and what marine resources they depend on for survival. It's early November and the team affixes a satellite transmitter to an adult female. They won't see her back on the Pribilof Islands until next July, and they hope the tag will stay on throughout winter and spring. Back at their offices in Seattle, the researchers begin tracking tagged animals via satellites.
In January 2014, host Emily Graslie accompanied Curator of Mammals, Bruce Patterson, on a field expedition into the bat caves of Kenya. In this second installment, the researchers collect bats at night. The next morning they release the captured bats and try to record the "sounds" made by the different species. Part of "The Brain Scoop" series.
A team of researchers from the University of Utah is perfectly situated to study rock arches. With support from the National Science Foundation, geologist Jeff Moore and his team are pioneering a new method of structural health monitoring to keep tabs on the structural integrity of geological landmarks. The researchers have discovered that each arch has its own "voice." The arches naturally vibrate, like a guitar string, with its own distinct resonant frequency. The team's research has important implications for the conservation and management of these natural structures. Part of the "Science Nation" series.
Iridium is a rare element used to light up cell phones and TVs. However, researchers have found a way to use a more common element to power electrical devices: copper. Researchers are also developing a better treatment for osteoarthritis through nanotechnology. Other segments include research into specialized metabolites and devices that translate sign language.

In January 2014, host Emily Graslie accompanied Bruce Patterson, Curator of Mammals, on a field expedition into the bat caves of Kenya. They were joined by media producers Greg Mercer and Emily Ward to document the experience. In this first installment, the team of researchers prepares to journey to Mt. Suswa. They have to travel deep into the cave before they encounter any bats. Part of "The Brain Scoop" series.
Modern society is very much defined by its access to electricity. What if researchers could advance sustainable energy technologies to the point where everyone around the world had access to clean, cheap energy sources? Richard Smalley, 1996 Nobel Prize winning chemist, called it the greatest challenge facing the world in the 21st century and coined the phrase "terawatt challenge." Researchers at the Quantum Energy and Sustainable Solar Technologies (QESST) Center are hoping to meet much of the terawatt challenge with solar technology alone by vastly improving the performance of photovoltaic cells. Part of the National Science Foundation Series “Science Nation.”
Scientists and researchers are working to understand the possible effects of Antarctic ice melt on global processes. Some areas that might be impacted include currents, water chemistry, and biological balance.
It's gang warfare when Africa's meerkats face danger. Wild Chronicles heads to Africa's Kalahari Desert where researchers studying a band of young meerkats find they rarely face danger alone. Segment of video from Wild Chronicles.
Host Lisa Van Pay meets researchers who study life in caves. The team explores Snowy River, a bright white crystalline formation found deep within Fort Stanton Cave in New Mexico, finding life and energy in unexpected places.
