 "Oil Filter" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn't look like a very big deal, but it could make a big difference for future environmental cleanups. Water passes through the mesh but oil doesn't, thanks to a nearly invisible oil-repelling coating on its surface. In tests, researchers mixed water with oil and poured the mixture onto the mesh. The water filtered through the mesh to land in a beaker below. The oil collected on top of the mesh, and rolled off easily into a separate beaker when the mesh was tilted.

 "Cotton Clues" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

A University of Texas at Austin scientist, working with an international research team, has developed the most precise sequence map yet of U.S. cotton and will soon create an even more detailed map for navigating the complex cotton genome. The finding may help lead to an inexpensive version of American cotton that rivals the quality of luxurious Egyptian cotton and helps develop crops that use less water and fewer pesticides for a cotton that is easier on the skin and easier on the land.

 "Cloud Seeding" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

The main job of pollen is to help seed the next generation of trees and plants, but a new study from the University of Michigan and Texas A&M shows that the grains might also seed clouds. The unexpected findings demonstrate that these wind-carried capsules of genetic material might have an effect on the planet's climate. And they highlight a new link between plants and the atmosphere.

 "Fat Chance" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

Maternal diet during pregnancy and lactation may prime offspring for weight gain and obesity later in life, according to Penn State College of Medicine researchers, who looked at rats whose mothers consumed a high-fat diet and found that the offspring's feeding controls and feelings of fullness did not function normally.

 "Spoiler Alert" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

MIT chemists have devised an inexpensive, portable sensor that can detect gases emitted by rotting meat, allowing consumers to determine whether the meat in their grocery store or refrigerator is safe to eat. The sensor, which consists of chemically modified carbon nanotubes, could be deployed in "smart packaging" that would offer much more accurate safety information than the expiration date on the package.

 "Word Pictures" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

When we look at a known word, our brain sees it like a picture, not a group of letters needing to be processed. That's the finding from a Georgetown University Medical Center (GUMC) study which shows the brain learns words quickly by tuning neurons to respond to a complete word, not parts of it.

 "Trapper Keeper" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

A new UC Berkeley study shows that if biomass electricity production is combined with carbon capture and sequestration in the western United States, power generators could actually store more carbon than they emit and make a critical contribution to an overall zero-carbon future by the second half of the 21st century.

 "Mood Monitor" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

It's common to hear complaints about our near-constant connection to our smart phones, but UConn researchers believe they can use the ubiquity of these devices to better screen for depression. Depression is an affliction that affects 350 million people worldwide, and one of the most crucial issues for mental health workers is detecting it in patients in its early stages. Researchers say smartphones have the potential to serve as "human sensors" by monitoring users in real time for symptoms of depression.

 "Spaced" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:31

Play may seem like fun and games, but new research shows that specific kinds of play are actually associated with development of particular cognitive skills. Data from a nationally representative study show that children who play frequently with puzzles, blocks, and board games tend to have better spatial reasoning ability.

 "Tick Talk" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:31

In the northeastern United States, warmer spring temperatures are leading to shifts in the emergence of the blacklegged ticks that carry Lyme disease and other tick-borne pathogens. At the same time, milder weather is allowing ticks to spread into new geographic regions. Conclusions on blacklegged tick emergence were based on nineteen years of data collected at the Cary Institute of Ecosystem Studies in Millbrook, N.Y.

 "Clockwork" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

The discovery of a new reset button for the brain's master biological clock could eventually lead to new treatments for conditions like seasonal affective disorder, reduce the adverse health effects of working the night shift and possibly even cure jet lag.

 "Litter Critters" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

In the city that never sleeps, it's easy to overlook the insects underfoot. But that doesn't mean they're not working hard. A new study from North Carolina State University shows that insects and other arthropods play a significant role in disposing of garbage on the streets of Manhattan.

 "Mighty Mites" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

Termites might not top the list of humanity's favorite insects, but new research suggests that their large dirt mounds are crucial to stopping deserts from spreading into semi-arid ecosystems. The results indicate that termite mounds could make these areas more resilient to climate change.

 "Elective Memory" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

People may have to "turn on" their memories in order to remember even the simplest details of an experience, according to Penn State psychologists. This finding, which has been named "attribute amnesia," indicates that memory is far more selective than previously thought.

 "Expanded View" -- The Discovery Files | File Type: audio/mpeg | Duration: 1:30

A study done by researchers at MIT has shown that a modified form of the superabsorbent chemical used in disposable diapers can expand brain structures to four and a half times their original size. The process called expansion microscopy will allow scientists to take super-resolution pictures of healthy and diseased tissue throughout the body using common microscopes.
