"Unreasonable Facsimile" -- The Discovery Files | Princeton University researchers have come up with a new twist on the mysterious visual phenomenon experienced by humans known as the "uncanny valley." That twist is that monkeys experience the same exact feeling.

"Tots with 'Tude" -- The Discovery Files | Defiant behavior from toddlers toward their mothers may not be a bad thing, according to researchers at the University of Texas at Austin and the University of Michigan. They studied the mother-child interaction of 14- to 27-month-old children and found this behavior may in fact reflect an emerging autonomy and healthy confidence. The study also indicated a correlation to the mother's behavior. Children with mothers exhibiting symptoms of depression were more likely to ignore requests and less likely to exhibit defiance -- possibly at risk of becoming overly passive. | 9/7/07 | Free | View In iTunes |

"Paper Power" -- The Discovery Files | It might look like a simple sheet of black paper, but it's really an incredibly novel source of power. Researchers at Rensselaer Polytechnic Institute have developed a unique nanocomposite paper that can provide steady power output comparable to a conventional battery as well as a quick burst of high energy like a supercapacitor. This power device can withstand extreme temperatures and can be rolled, twisted, folded -- and even cut into pieces -- with no loss of mechanical integrity or efficiency. Plus, it's even environmentally safe. Talk about superpower!! | 8/31/07 | Free | View In iTunes |

"Cell Gels" -- The Discovery Files | University of Delaware scientists have developed a novel biomaterial that offers great promise for helping to repair and regenerate human tissue. Their hydrogel invention -- which has surprising antibacterial properties -- could be injected into a wound, where it rigidifies nearly on contact. This opens the door to possibly delivering a targeted payload of cells and antibiotics to repair damaged tissue -- offering a myriad of uses including regenerating healthy tissue in a cancer-ridden liver or healing a biopsy site. | 8/23/07 | Free | View In iTunes |

"Tomato Wars" -- The Discovery Files | A team of scientists from Cornell University is studying the evolutionary struggle in which plants and diseases are in a continual war to outdo each other. Plants build up a resistance to a disease, but then the pathogens quickly evolve to overcome the plants' defenses. The Cornell team is studying a battle involving a bacterium that infects tomatoes by injecting a special protein into the plant's cell to undermine the plant's defense system. More evidence of that ongoing arms race in the plant world! | 8/13/07 | Free | View In iTunes |

"Cast System" -- The Discovery Files | Turns out the builders of a nearly 5000-year old set of structures have a great deal of wisdom to offer to the current day construction industry. The mysteries surrounding the building of the Great Pyramids of Giza have perplexed scientists for centuries, but a research team out of Drexel University offers some answers. Evidence indicates that parts of the Pyramids were built using an early form of concrete. Blocks were cast--not carved--using a limestone concrete. Replicating the recipe for this ancient technique could provide a cost-effective, easily accessible, long-lasting, and much more environmentally friendly alternative to current cement building materials. | 7/31/07 | Free | View In iTunes |

"Eye Catching" -- The Discovery Files | Keeping an eye on the ball, or observing others passing by, isn't quite as simple as we might think. Research from the University of Pennsylvania shows that the targeting system of human vision is quite incredible. Seeing motion actually involves two distinct processes that require the brain and the eye to team up. The researchers also found that people exhibit a range of capabilities in sensing and following motion, so the visual experience for a particular event is not the same for all observers. | 7/19/07 | Free | View In iTunes |

"Pilots of the Caribbean" -- The Discovery Files | Until recently, there's been little understanding of the evolutionary history of tropical frogs, but a discovery out of Penn State offers some light to this "black hole." The research team found that nearly all of the 162 Caribbean frog species originated from a single species that rafted on a sea voyage from South America 30 to 50 million years ago. Surprising news... never before had a single origin been identified and it's rare that close relatives dominate such a major geographic region.

"Tropical Punch" -- The Discovery Files | A study from an international team of scientists sheds some light on one of the biggest mysteries in climate science. What happens to the 8 billion tons of carbon emissions resulting from motor vehicles, factories, etc. each year? Earlier estimates indicated that forests in the northern regions were responsible for a good portion of the carbon uptake. New information from aircraft samples reveals those numbers to be much lower, but it appears that forests in the tropical regions are doing significantly more than expected to offset the industrial emissions. Not exactly a K.O. (or should we say CO) of global warming, but certainly one round for the tropics in this fight. | 7/11/07 | Free | View In iTunes |

"Fly-ing Bricks" -- The Discovery Files | Seems everything's going green these days -- even bricks! National Science Foundation grantee Henry Liu is developing bricks made from fly ash (a residue from coal-fired power plants). The new brick on the block holds promise for great ecological benefits over its clay counterpart. Liu says manufacturing of these "green" bricks conserves energy, costs less, and doesn't contribute to air pollution or global warming... plus, it puts to use some of that waste heap (piling up to nearly 70 million tons each year!). Additional safety testing of the material and preparing it for the market is underway. Perhaps soon... "green" house could have a whole new meaning. | 6/29/07 | Free | View In iTunes |

"Hot Sounds" -- The Discovery Files | Research is unlocking secrets of the Sun's interior, which has been a mystery for decades. Scientists have long wondered why the Sun's chromosphere (a.k.a., 'ring of fire') is much hotter than the surface of the star. A recent discovery reveals that sound waves -- vibrations from the Sun's interior -- are escaping through magnetic cracks to create fountains of hot gas that shape and power the 'ring.' Another piece in solving the puzzle of the 'ring' which is connected to our climate and the ozone layer. | 6/21/07 | Free | View In iTunes |

"Reef Savers" -- The Discovery Files | The establishment of marine reserves is successful in protecting fish and other marine life from overfishing, but now research from the University of Exeter shows the benefit is even greater than that. The reserves could also help coral reefs to survive... because algae and seaweed, which are usually detrimental to coral, are controlled by grazing parrotfish. Kind of a reversal of roles in the marine world -- coral reefs, which have supported thousands of fish and other marine species for millions of years, are now getting a helping "hand" from fish. | 6/7/07 | Free | View In iTunes |

"True Blue Lizards" -- The Discovery Files | In nature, putting the other guy first seems contradictory to an animal's goals of survival and passing on its genes, so researchers have been trying to understand why the blue side-blotched lizard will step forward to battle an intruding aggressor, even though it could mean sacrificing its own chances to successfully mate. Now scientists have reported the first direct evidence that cooperative behavior in side-blotched male lizards arises from their genes. The findings, published in the May 9 Proceedings of the National Academy of Sciences by University of California--Santa Cruz's Barry Sinervo and colleagues, represent some 20 years of research into the altruistic or "self-sacrificing" behavior. | 8/7/06 | Free | View In iTunes |

"Fossil Find" -- The Discovery Files | Far above the Arctic Circle, paleontologists have discovered a new fossil species that bridges the evolutionary gap between land and sea animals--an animal that is both fish and tetrapod. The skeleton indicates that the animal could support its body under the force of gravity, whether in very shallow water or on land. | 8/7/06 | Free | View In iTunes |
