More From This Expert... Science The Discovery Files Blindsided -- The Discovery Files   Heard 5860 times People who have been blind from birth make use of the visual parts of their brain to refine their sensation of sound and touch, according to an international team of researchers led by neuroscientists at Georgetown University Medical Center. 1:30   Play    Download Science The Discovery Files Tell and Show -- The Discovery Files   Heard 3406 times Cognitive psychologists at the University of Pennsylvania and University of California have shown that an image displayed too quickly to be seen by an observer can be detected if the participant first hears the name of the object. 1:30   Play    Download Science The Discovery Files Uncommon Sense -- The Discovery Files   Heard 3077 times Researchers at Purdue University have developed a potential new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics. 1:30   Play    Download Science The Discovery Files Cheek Check -- The Discovery Files   Heard 3329 times Engineers and physicians from NorthShore University Health System have developed a method to detect lung cancer by merely shining diffuse light on cells swabbed from patients' cheeks. In their study, the analysis technique was able to differentiate individuals with lung cancer from those without. 1:30   Play    Download Science The Discovery Files Emotional Recall -- The Discovery Files   Heard 3109 times Cornell University researchers find that emotions can alter a child's memory and that these distortions could directly impact court cases by affecting decisions made about the reliability of a child witness. 1:30   Play    Download Science The Discovery Files Spit Take -- The Discovery Files   Heard 3327 times Researchers have discovered why strands of some fluids containing polymers form beads when stretched, findings that could be used to improve industrial processes and for administering drugs. 1:30   Play    Download Science The Discovery Files Got Your Bac -- The Discovery Files   Heard 3194 times While the ways in which the cells of drug resistant bacteria become resistant are understood at the cellular level, until now, the bacteria's survival strategies at the population level remained unclear. A new study at Boston University and Harvard University reveals that a surprisingly small percentage of bacteria actually become highly resistant supermutants. In fact, most of the bacteria in their study survived without being resistant to the effective dose of antibiotics in the environment. 1:30   Play    Download Science The Discovery Files Waste Treatment Plant -- The Discovery Files   Heard 3113 times Isolating a gene that allows a type of fern to tolerate high levels of arsenic, Purdue University researchers hope to use the finding to create plants that can clean up soils and waters contaminated by the toxic metal. 1:30   Play    Download Science The Discovery Files Just Chillin' -- The Discovery Files   Heard 3085 times New findings from the Fred Hutchinson Cancer Research Center may help explain the mechanics behind the widely documented phenomenon of living creatures being totally frozen and then successfully brought back to life. 1:30   Play    Download Science The Discovery Files Slice of Life -- The Discovery Files   Heard 3327 times Princeton University scientists may have discovered the oldest fossils of animal bodies. These findings push back the clock on the scientific world's thinking regarding when animal life appeared on Earth. 1:30   Play    Download Science The Discovery Files Wheel Deal -- The Discovery Files   Heard 3359 times While the evolution from the Neolithic stone wheel to the sleek wheels of today's racing bikes can be seen as the result of human ingenuity, it also represents how animals, including humans, have come to move more efficiently over millions of years on Earth, according to a Duke University engineer. 1:30   Play    Download Science The Discovery Files Blow Flies -- The Discovery Files   Heard 4207 times A Caltech biologist and his research team have identified how the antennae of fruit flies process the feeling of wind and then how the flies respond by standing completely still. 1:30   Play    Download Science The Discovery Files Laptop Learning -- The Discovery Files   Heard 3119 times Despite the distraction potential of laptops in college classrooms, research from the University of Michigan shows that they can actually increase students' engagement and learning. 1:30   Play    Download Science The Discovery Files Sponge Bath -- The Discovery Files   Heard 3226 times When loaded with an anticancer drug, a delivery system based on a novel material called nanosponge is three to five times more effective at reducing tumor growth than direct injection. 1:30   Play    Download Science The Discovery Files Buy Buy Blues -- The Discovery Files   Heard 3537 times According to a Cornell University professor of psychology, consumers found that satisfaction with experiential purchases -- from massages to family vacations -- starts high and increases over time. In contrast, spending money on material things feels good at first, but actually makes people less happy in the end. 1:30   Play    Download Science The Discovery Files Growth Light -- The Discovery Files   Heard 3372 times Researchers have developed a way to enhance how brain tumors appear in MRI scans and during surgery, making the tumors easier for surgeons to identify and remove. 1:30   Play    Download Science The Discovery Files Glacial Globe -- The Discovery Files   Heard 3424 times Geologists at Harvard University found evidence that sea ice extended to the equator up to 716.5 million years ago, bringing new precision to a snowball Earth event long suspected to have taken place around that time. 1:30   Play    Download Science The Discovery Files Letter Carrier -- The Discovery Files   Heard 3608 times Mayo Clinic neuroscientists have demonstrated how brain waves can be used to type alphanumerical characters on a computer screen. By merely focusing on the letter q in a matrix of letters, for example, that q appears on the monitor. 1:30   Play    Download Science The Discovery Files Hooked On Photonics -- The Discovery Files   Heard 3594 times Purdue University researchers have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in homes and offices of the future. 1:30   Play    Download Science The Discovery Files On The Fly -- The Discovery Files   Heard 3394 times Using high-speed cameras and computer models, Cornell researchers have shown exactly how fruit flies maneuver through the air, and how they keep stable even when a whoosh of wind knocks them off course. 1:30   Play    Download
