Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors.

Sarah Brosnan, a psychologist and neuroscientist at Georgia State, has released a study helping to prove that primates share similar feelings of inequity as humans, and she will extend the research with a five year National Science Foundation grant. In the next round of research Brosnan will work with Bart Wilson at Chapman University to do similar hands-on and computer game-like experiments on both humans and primates. The idea is to better understand how economic decision making strategies evolved and which if any are uniquely human.
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.

Disease, pollution, and loss of habitat are killing off hundreds of species of amphibians. One of the biggest threats right now is an aquatic fungus called chytrid that infects the skin of these historically tough, resilient creatures. With funding from the National Science Foundation, Biologist Vance Vredenburg studies the disease and shares his research with scientists who are dealing with this crisis on every continent where amphibians live.
The Pajaro Valley, in the Monterey Bay area of California, is ideally suited for agriculture. In fact, the Pajaro Valley and the nearby Salinas Valley produce nearly half of the strawberries grown in the United States yearly. But, the water source for the valley is a confined underground aquifer that is slowly being depleted. In January of 2011, the American Institute of Mathematics held a Sustainability Problems workshop with the goal of bringing together mathematicians and industry representatives to work on a variety of sustainability problems, including renewable energy, air quality, water management, and other environmental issues.

With support from the National Science Foundation, Astrobiologist Richard Hoover really goes to extremes to find living things that thrive where life would seem to be impossible--from the glaciers of the Alaskan Arctic to the ice sheets of Antarctica. He thinks it is even possible that over the course of billions of years, life has spread around the solar system--a sort of cosmic cross pollination. Microbes could live in the ice deep within comets, frozen there for eons until a collision with another planet or moon delivered them to a new home.
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even Earth, for that matter. Burrows reveals that the biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae, and he has recently created 3D computer simulations showing the actual moment of a star's death. His simulations are revealing more about these stellar performances.
Michael Goodisman is digging up the dirt on yellow jackets' peculiar lives by studying their nests, behavior, and genetic make-up. With support from the National Science Foundation, he is getting a better understanding of what drives their complex family relationships. Yellow jackets, like honey bees and fire ants, exist in a sophisticated social hierarchy. Unlike other animals that travel in packs or swim together, these social insects will literally sacrifice their own survival in support of their hives, nests, and colonies.
Think all squash balls bounce the same? Think again! Two MIT scientists look into what makes things bounce better than others. Ready for some physics? Part of the "Science Out Loud" series.
Kathy Blake is blind but two years ago she got a glimmer of hope. She heard about an artificial retina being developed by a company called Second Sight and the Doheny Eye Institute in Los Angeles. It was experimental, but Kathy was the perfect candidate. With funding from the National Science Foundation, a camera is built into a pair of glasses, sending radio signals to a tiny chip in the back of the retina. The chip, small enough to fit on a fingertip, is implanted surgically and stimulates nerves that lead to the vision center of the brain.
Sunspots have fascinated sky gazers through the ages. Now state-of-the art telescopes combined with the muscle of a supercomputer called “Bluefire” are allowing scientists to accurately model these mysterious structures, and unlock their secrets. Michael Knoelker and Matthias Rempel are solar scientists working at the High Altitude Observatory at the National Center for Atmospheric Research, known as NCAR, in Boulder, Colorado. With support from the National Science Foundation, their study of sunspots is critical to the understanding of how stars, like the sun, produce magnetic fields which is still one of the big unanswered questions in stellar astrophysics.
The National Science Foundation in cooperation with the Marinette Marine Corporation (MMC) and the University of Alaska, Fairbanks has successfully launched the R/V Sikuliaq, a next-generation global class research vessel. MMC is the Wisconsin shipyard that built the ship, with funding provided by NSF through the American Recovery and Reinvestment Act of 2009. UAF's School of Fisheries and Ocean Sciences will operate the ship as part of the U.S. academic research fleet. The new vessel's name, Sikuliaq, pronounced “see-KOO-lee-ack,” is an Inupiat word meaning young sea ice. Part of the National Science Foundation Series “Science Nation.”
Cubelets are magnetic, electronic building blocks, each with a small computer inside, that can be connected in many different ways to move around a table, follow a hand signal, turn on a light, play sounds, or do many other creative tasks. They were developed by Eric Schweikardt and his team at Modular Robotics, with support from the National Science Foundation’s Small Business Innovation Research (SBIR) program. These 21st century building blocks are meant to help kids learn about the basics of robotics while boosting their confidence to solve problems.
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 steps of making scientifically sound observations. Part of the Science Video Vocab series.
Conservation scientist Glen Gates at the Walters Art Museum in Baltimore is working on new ways to protect museum-quality silver from the ravages of time. Fine silverware and silver pieces on display at museums are exposed to air and tarnish. Every time someone polishes the silver, even under the careful supervision of conservation experts, a little bit of the silver wears away. Gates and colleague, Physics professor Ray Phaneuf at the University of Maryland, are working on a non-destructive method to preserve silver artifacts. With support from the National Science Foundation, they’re developing a nanometer-thick transparent coating that seals the silver. This coating keeps silver from tarnishing and eliminates the need to polish it.
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."
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.

Professor Michael Sailor hopes to dramatically change how cancer is being treated. With support from the National Science Foundation, he is on a quest to create nanoparticles that travel the bloodstream, latch onto cancers in their earliest stages, and destroy them.
What the microscope did to unlock the secrets of biology, the chemiscope is intended to do, to revolutionize chemistry. The ultimate goal is to observe chemistry in the act, to see the making and breaking of bonds in real-space and real-time. Part of the National Science Foundation Series “Science Nation.”
