At the National Science Foundation-funded Center for Environmental Implications of Nanotechnology (CEINT), headquartered at Duke University, scientists and engineers are researching how nanoscale materials affect living things. One of CEINT's main goals is to develop tools that can help assess possible risks to human health and the environment. A key aspect of this research happens in mesocosms, which are outdoor experiments that simulate the natural environment. These simulated wetlands in Duke Forest serve as a test bed for exploring how nanomaterials move through an ecosystem and impact living things. Part of the “Science Nation” series.
Presents a brief history of the United States Geological Survey (USGS) as well as the significance of its work and mission in today’s world.
This episode discusses the scientific method and the importance of using credible sources when conducting research. Other topics covered include control group, constants, independent variable, and dependent variable. Part of "The Amoeba Sisters" series.
The Earth has many natural resources humans use every day. Students also investigate the difference between renewable and nonrenewable resources.
Scientists know that Earth’s climate has changed many times over billions of years and that Earth’s climate is always changing. Students will understand that climatologists are scientists that look for evidence from the past to help study climate change. This program also highlights the natural factors that affect climate change as well as the connection between the burning of fossil fuels and climate change. Part of the "Real World Science" series.
Natural selection is a process which affects every species on Earth, including humans. Illustrates how it continues to affect humans all in fundamental ways that will determine the future survival as the species. Includes a brief explanation of natural selection, examples of how it is operating all around humans, how it has affected human evolution, and how it is still affecting daily lives. Concludes with the reciprocal view of how modern human society is affecting the processes in the environment, and the consequences for the future of life on Earth.
From cleaning supplies to pharmaceuticals, surfactants are the compounds that make soap bubbly, paint spread smoothly, and medication dissolve more easily. Most surfactants are currently made from non-renewable petroleum sources and many of these surfactants don’t break down easily after they are discarded. Some can persist in the environment for decades. Their widespread use and environmental persistence has raised concerns about toxicity. At the University of Arizona, Jeanne Pemberton and her cross-disciplinary team work to create new “green” surfactants based on sugars that are generally known as glycolipids. With support from the National Science Foundation, Pemberton and her team are exploring the recent discovery of a versatile synthesis that allows production of many different types of glycolipids in large quantities. Some of these glycolipids are modeled after naturally occurring biosurfactants and some can be produced relatively inexpensively using renewable natural resources.

Experiments illustrate the presence and properties of: 1) saccharides (glucose and starch) in fruits and vegetables; 2) lipids (fats) in nuts and vegetable oils; and 3) proteins in eggs, meat, and milk. Emphasizes that chemistry is all around us.
Whether they arise from human causes or forces within planet Earth itself, natural disasters threaten life and civilization with what seems to be growing frequency. Studies troubling developments in marine, arctic, wetland, and urban environments while highlighting research opportunities that may help prevent future catastrophes. Coral reef decay, Everglades habitat loss, polar ice disappearance, and global warming are all analyzed. Looks at earthquake prediction, hurricane and tornado tracking, air pollution monitoring, tsunami warning systems, and the cleanup of toxic flood sediment in New Orleans.
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.”
A cycle or rhythm is a repetition of behaving in a regular pattern. There are many natural cycles for living and nonliving things on earth. Covers circadian rhythm (behavior based on a 24-hour cycle), annual rhythm (based on a yearly cycle), the water cycle, and the oxygen and carbon cycle. Highlights familiar examples of each. Quiz after summary.
In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But questions about its impact on the air and water are far from settled. With support from the National Science Foundation, University of Colorado environmental engineer Joseph Ryan heads a team gathering data on the pros and cons of oil and natural gas development, including the use of hydraulic fracturing. Part of the National Science Foundation Series “Science Nation.”
Natural selection is a mechanism of evolution. In this episode, Pinky and Petunia discuss the relationship of natural selection and antibiotic resistance in bacteria. Part of "The Amoeba Sisters" 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.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the hazards of flooding caused by river floods, coastal floods, and flash floods. Part of the Science Video Vocab series.
Paleo-anthropologists believe Homo sapiens evolved in Africa 100-200 thousand years ago, and eventually moved out of Africa to populate the globe. But, how can researchers trace the specifics of that human migration? With support from the National Science Foundation, Florida Museum of Natural History Mammologist David Reed has undertaken a novel approach. He studies the genetic diversity and evolution of the human parasite that hitched a ride the whole way: lice.
Wyoming has long been known as an energy exporter, from oil to natural gas to coal. The state is now booming with two other resources: wind energy and qualified technicians trained to build, install, and service the growth in wind turbine technology. With National Science Foundation funding, Laramie County Community College in Wyoming is becoming a national leader in training.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on earthquakes and the roll tectonic forces play in their occurrences along fault lines. Part of the Science Video Vocab series.
Sea spray aerosols occur naturally in the salty ocean air, and there’s much more in each of those tiny bursting bubbles than salt. They’re bursting with ocean life, from bacteria to phytoplankton--even viruses. Because sea spray aerosols seed clouds, they affect the climate. With support from the National Science Foundation (NSF), atmospheric chemist Kimberly Prather of the University of California, San Diego, and chemist Vicki Grassian of the University of Iowa are leading a team of scientists around the country who are working to better understand what role sea spray aerosols play in weather and climate change climate models. Part of the National Science Foundation Series “Science Nation.”
