With support from the National Science Foundation, chemist Kent Kirshenbaum and his team at New York University are engineering molecules to mimic the shapes, structures, and functions of natural proteins. The ultimate goal of this biomimetic chemistry research is to develop a reliable way to build synthetic proteins that can be put to work at the industrial scale. Part of the "Science Nation" series.

Go behind the scenes with Angelina and investigate the equipment and engineering skills needed to recreate ocean habitats. Explore a typical workspace of an aquarium and get a feel for the everyday problem solving skills needed as an aquarist. Part of the "Aquarist" series.
Paper is used for many things which can lead to excessive waste. New environmental programs focus on decreasing the consumption of usage as well as the benefits of recycling.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "The Cell Machinery," "A Variety of Cells," "Organic Molecules: The Building Blocks of Life," "Prokaryote Evolution and Diversity," and "Independently Living Eukaryotic Cells."
The United States leads the world in producing trash. In the episode, Joel Greene and his crew visit a landfill to learn what happens to all the trash that doesn’t get recycled. Part of the Curiosity Quest Series.
Joel and the Curiosity Quest crew visit Big Toys Factory to learn how playground equipment is made. The toys from this factory are made from recycled materials. Part of the Curiosity Quest Series.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, author Michael Pollan defines genetically engineered foods. Part of the Nourish Short Films Series.
Can the wind provide us with all of our power? Along with cutting-edge wind farms and new turbine designs, this production meets renegade inventor Doug Selsam as he builds the world's first flying turbine, a device that may just change our world.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term simple machine. Part of the Science Video Vocab Series.
Robotics is gaining more and more ground in all areas of everyday life. It is increasingly common to see robots in the industrial field, in the workplace, or just being used for fun. Recently, robots have found their place in the educational field. This episode traces the evolution of robots and discusses the technological advances made in the world of robotics.
Explore the dynamic work environment of an electrical engineer who oversees large industrial projects. Watch as engineers interact with one another and use cutting-edge 3-D modeling. Learn how to become a licensed professional engineer. Part of the "Career Connections" series.
University of California, Berkeley seismologist Peggy Hellweg discusses the difference between a tremor and an earthquake. She also explains how TremorScope stations record deep tremors along the San Andreas Fault in central California. These stations reveal complex faulting behavior in the deep crust that is surprisingly different from earthquakes in the upper crust.
A recycling coordinator takes viewers through the recycling process for cans, plastics, and newspapers, emphasizing the useful products and hundreds of jobs that are created by recycling. The machinery and processes used at Material Recovery Facilities produce recycled materials for clothing, benches, chairs, cardboard, and paper products. Demonstrates composting for home and community gardens.
Students will trace the history of chemistry and study accounts of how chemistry developed from a practical discipline into a science. This episode also presents a current, real-life application of chemistry by illustrating the process of the refining and purifying pure silicon for advanced electronics, such as cell phones and solar cells. Part of the Chemistry: Challenges and Solutions Series.
Corals get much of their energy from symbiotic algae that live inside their cells. When ocean temperatures rise beyond a certain threshold, the algae’s photosynthetic machinery may be damaged and produce harmful reactive oxygen molecules. This animation shows how corals subsequently eject their algae in a process called coral bleaching, which causes the corals to turn white and often eventually die.
Mining traditionally has destroyed vegetation and topsoil as it takes minerals from the ground. New techniques and increased environmental awareness has recently led to new land reclamation experiments. Adding earthworms and bacteria to restore the land is one such venture. Highlights bioremediation--using living organisms-- to clean up heavy metals left as mining residue.
Coastlines face numerous threats. Hurricanes, tsunamis, and sea level rise are a few of the dangers that keep coastal communities on edge. With over half of the U.S. population living near the coast, it’s critical to collect and share accurate information on the environment during extreme weather events, and NOAA is leading these efforts. Part of the "Danger Zone" series.
This award-winning documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory, examines how LIGO is spearheading the new field of gravitational wave astronomy and opening a whole new window on the universe. LIGO's exquisitely sensitive instruments may ultimately take scientists farther back in time than ever before, catching, perhaps, the first murmurs of the universe in formation.
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.”
A documentary film highlighting recent and past USGS (US Geological Survey) research in the Lake Tahoe Basin. It features USGS science activities conducted by hydrologists, geologists, geographers, computer modelers, and biologists. Some of USGS science detailed includes water quality monitoring, streamgaging, and use of aerial photography. The use of consistent, reliable, long-term data and maps are crucial for evaluating and maintaining the lake and basin.
