With support from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA), Georgia Tech biochemist Nicholas Hud and a team at the Center for Chemical Evolution (CCE) are working to chip away at how life on earth began. They are homing in on how chain-like chemicals called polymers first came together and evolved three-and-a-half to four billion years ago. Part of the National Science Foundation Series “Science Nation.”
There's a most unusual gym in ecologist Sonia Altizer’s lab at the University of Georgia. The athletes are monarch butterflies, and their workouts are carefully monitored to determine how parasites impact their flight performance. With support from the National Science Foundation, Altizer and her team study how animal behavior, including long distance migration, affects the spread and evolution of infectious disease. Part of the National Science Foundation Series “Science Nation.”
One might never know it, but the seemingly quiet Harvard Forest in Massachusetts is actually hard at work. Like other forests, it’s busy doing some serious global housekeeping, which is being monitored by scientists at Harvard University. With support from the National Science Foundation, researchers are studying forest ecology. That research includes determining how the forest responds to carbon dioxide in the atmosphere. Part of the National Science Foundation Series “Science Nation.”
In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.
Most people see a vegetable when they see a spinach leaf, but in this lab, they see the potential to create heart tissue. Students at Worcester Polytechnic Institute are training to be leaders in bioengineering, and they are thinking outside the box to develop practical, commercially viable technologies that fulfill critical unmet needs. Part of the "Science Nation" series.
Since the time of the ancient Greeks, humans have been using spider silk to dress wounds. Scientists now know spider webs not only have healing qualities, they can be stronger than steel. University of Wyoming Molecular Biologist Randy Lewis adds an almost science fiction aspect to the study of spider silk: making large quantities of it by “growing it” in goat’s milk. With funding from the National Science Foundation, Lewis has cloned and sequenced genes for the proteins that make up five different spider silks, some stronger than Kevlar, others more elastic than nylon.
Rigoberto Delgado, a health economist at the University of Texas, wants to help health-care professionals target their limited resources. His team is using geospatial mapping science and predictive analytics to forecast areas of highest risk for illness. The researchers want to figure out where to send the mobile health clinics to help prevent potential outbreaks. Part of the "Science Nation" series.
For as long as parents and babies have been smiling, laughing, and cooing at each other, scientists still have a lot of questions about just how these interactions help infants develop. With support from the National Science Foundation, University of Miami psychology professor Daniel Messinger and his colleagues want to learn more about child development by studying how moms, dads, and babies respond to each other. Part of the National Science Foundation Series “Science Nation.”

Part of the Science Video Vocab series.
It’s a freezing cold day inside the National Ice Core Laboratory (NICL) in Denver, Colorado. That’s because the NICL is a facility for storing and studying ice cores recovered from the polar regions of the world. And, saws are buzzing, as scientists from all over the U.S. are measuring and cutting pieces of precious Antarctic glacier ice to take back to their labs for research. Part of the National Science Foundation Series “Science Nation.”
Montana State University plant pathologist Gary Strobel travels the seven continents to collect samples of endophytes. Endophytes are microorganisms that live within the living tissue of a plant. With support from the National Science Foundation, Strobel, engineer Brent Peyton and their team, have discovered that endophytes have the ability to make diesel-like fuel. And, amazingly, it takes the team just a few weeks to create the fuel. Part of the National Science Foundation Series "Science Nation."
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.
Patients who have suffered devastating facial injuries sometimes go to great lengths to hide themselves from public view. At the University of Illinois at Urbana-Champaign, civil and mechanical engineer Glaucio Paulino saw the possibilities of combining engineering and medical skills to tackle the complex challenge of facial reconstruction. Part of the National Science Foundation Series “Science Nation.”
In the Pacific Northwest, people are stripping moss for the horticultural trade at such an alarming rate that it's now illegal to harvest it. Ecologist Nalini Nadkarni knows that moss is a key component to the eco-system of the region, which makes it important to study. But this globe-trotting scientist at The Evergreen State College needed a lot of help recording research data from some folks who have much more time than she does. Where better to find potential research assistants with lots of time on their hands than the nearby medium security Cedar Creek Corrections Center? With support from the National Science Foundation, Nadkarni’s idea has been so successful that now the prisoners are starting bee keeping and composting programs, in addition to growing and recording data about moss.
The process known as the scientific method gives scientists a format for engaging in a step-by-step approach to come up with a reasonable solution to a proposed hypothesis. It is important for students to understand and use the scientific method when solving problems and answering questions. This program identifies the steps of the scientific method and provides real-world examples of the scientific method being used to solve everyday problems. Part of the "Real World Science" series.
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.
Invasive animals are often most abundant in habitats impacted by humans. Understanding why this is true may reveal important insights about the ecological impact of many invasive species. The invasive fire ant, Solenopsis invicta, is a notoriously pesky species that benefits when humans disturb natural areas. With support from the National Science Foundation, Dr. Joshua King at the University of Central Florida and Dr. Walter Tschinkel at Florida State University have been exploring the underlying causes and consequences of the association of fire ants with human-altered ecosystems. Part of the National Science Foundation Series “Science Nation.”
As a boy growing up in Brazil 40 years ago, Marc Meyers marveled at the lightweight toughness of toucan beaks that he occasionally found on the forest floor. Now, with support from the National Science Foundation, the materials scientist and mechanical and aerospace engineer at UC San Diego, is conducting the first ever detailed engineering analysis of toucan beaks. He says makers of airplanes and automobiles may benefit from his findings. In fact, panels that mimic toucan beaks may offer better protection to motorists involved in crashes.
