Mark 06/29/2007It should be called dumbing down science. No self-respecting science show should have shows on "dieting". Today's show had a review of a book on dieting myths. Very few studies cited, but ...

- Scientists Mark 25 Years of HIV Research
(0mb)
Fri, 09 May 2008 18:05:46 -0400
In May 1983, the first scientific papers were published describing the possible connection between a retrovirus and the development of AIDS. The virus went on to become known as HIV. Experts discuss whether, 25 years later, scientists any closer to a cure for AIDS or to a vaccine to prevent HIV transmission. - Study: Sahara Gradually Dried Up Over 6,000 Years (0mb)
Fri, 09 May 2008 18:05:40 -0400
What made the Sahara Desert go dry — and are there ancient waters still hidden below the sands? In a controversial study published in the journal Science researchers argue that the drying of the Sahara took place over thousands of years — not suddenly as was previously thought. - Mysterious Memristor: Electronics' Missing Link? (0mb)
Fri, 09 May 2008 18:05:32 -0400
Introductory electronics classes focus on circuit diagrams involving combinations of resistors, capacitors and inductors. Now, researchers have discovered a fourth passive circuit element — one that fills in a gap in equations describing relationships between voltage, current and magnetic flux. - Common Weedkiller May Cause Hormonal Problems (0mb)
Fri, 09 May 2008 18:05:27 -0400
Researchers report that atrazine, the second-most-applied weedkiller in the U.S., may be able to disrupt hormonal signaling in humans. The herbicide, which has been banned in Europe, is suspected of playing a role in sexual abnormalities in fish, frogs and other aquatic organisms. - Is It Better to Eat Locally or Eat Differently? (0mb)
Fri, 09 May 2008 18:05:19 -0400
When it comes to greenhouse gas emissions, what you eat may be more important than where your food comes from. A new study finds that replacing red meat and dairy products with chicken, fish or vegetables could have the same impact as shifting to an entirely locally-grown diet. - TV Viewers Prepare for Digital Transition (0mb)
Fri, 09 May 2008 18:05:11 -0400
In February 2009, all full-power broadcast television stations in the U.S. will stop analog transmissions and begin broadcasting only in digital. Viewers who have cable or satellite are fine, but those who have older TVs receiving over-the-air signals may need to buy converters. - Life Expectancy Declines for Poor Women in U.S. (0mb)
Fri, 02 May 2008 18:04:55 -0400
Women living in America's poorest counties have seen their average life expectancy decline in recent years. New research shows that the gaps between the best-off and worst-off groups are widening — as much as 18 years between the two — in connection with smoking, high blood pressure and obesity. - Advances in Gene Therapy Treatment for Blindness (0mb)
Fri, 02 May 2008 18:04:40 -0400
Researchers using a gene therapy technique to treat one form of congenital blindness have reported some success. Two teams of scientists have used modified viruses injected into the eye to partially restore vision to people who have Leber congenital amaurosis, an illness that results in the degradation of the retina. - U.S. Carbon Footprint Difficult to Reduce (0mb)
Fri, 02 May 2008 18:04:35 -0400
According to a new survey, even the people in the U.S. with the lowest energy usage have a carbon footprint about twice as high as the average global citizen. What changes can an American make to have a significant effect on emissions? - Peering into the Human Brain with fMRI Techniques (0mb)
Fri, 02 May 2008 18:04:17 -0400
What's really going on inside your head when you make a decision, make a mistake, or have a few drinks? Researchers are using fMRI techniques to monitor blood flow through the brain and are hoping to shed light on the mysterious inner workings of the human mind. - Salt Water Irrigation Yields Tasty Tomatoes (0mb)
Fri, 02 May 2008 18:04:11 -0400
Researchers report that growing cherry tomatoes in diluted seawater can make them tastier and richer in antioxidants. The findings could encourage the use of slightly brackish water in tomato agriculture, extending precious supplies of fresh water. - Building a More Sociable Robot (0mb)
Fri, 25 Apr 2008 18:08:51 -0400
Can't find anyone who wants to hang out this weekend? Help may be on the way. Inventors are working to develop robots that can interact with people on a deeper level: communicating, responding to emotion and operating under specific rules of social behavior. - T. Rex Protein Evidence Links Dinosaurs to Birds (0mb)
Fri, 25 Apr 2008 18:08:43 -0400
Analysis of proteins found in a scrap of collagen from a 68-million-year-old Tyrannosaurus rex leg bone provides strong evidence for the idea that dinosaurs are the ancestors of modern-day birds. Paleontologist Mary Higby Schweitzer talks about the finding and what it means for our understanding of evolution. - PETA Offers Incentive for Test-Tube Meat Research (0mb)
Fri, 25 Apr 2008 18:08:35 -0400
Animal rights group PETA is offering a $1 million prize for the development of commercially-viable "test-tube meat" — real meat grown through a lab process, not from a live animal. To win, the lab-grown meat must have a taste and texture indistinguishable from real chicken flesh. - Pine Forests Destroyed by Beetle Takeover (0mb)
Fri, 25 Apr 2008 18:08:29 -0400
Canadian forests are being hit hard by an outbreak of the mountain pine beetle. Though the beetles are small — less than 1/3 of an inch long — they're hungry, and bore through the wood of a variety of pine tree species. Ecologists are worried that the death of so many trees will have a significant impact on the carbon balance in North America. - Bats Plagued by Mysterious 'White-Nose' Disease (0mb)
Fri, 18 Apr 2008 18:04:43 -0400
Wildlife experts are trying to determine what's causing hibernating bats in the Northeast to die en masse. The condition has been dubbed "white-nose syndrome," after a white fungus seen on bats' noses. Researchers are racing to explain the deaths — and keep the disease from spreading. - Sachs Explains 'Economics for a Crowded Planet' (0mb)
Fri, 18 Apr 2008 18:04:34 -0400
Economist Jeffrey Sachs says that the world's population, climate change, poverty and resource use are all closely intertwined. In his book Common Wealth, Sachs discusses the intersection of economics and the environment and argues that humanity must address global problems on a global scale. - Meltwater Can Quickly Crack Glaciers (0mb)
Fri, 18 Apr 2008 18:04:23 -0400
Scientists in Greenland have found that lakes of water on a glacier's surface can quickly cut all the way through to the base of the ice. A study in the journal Science describes an 11 billion-gallon lake of meltwater draining completely within 24 hours — a flow rate exceeding that of Niagara Falls. - Do Warmer Temps. Really Yield Stronger Storms? (0mb)
Fri, 18 Apr 2008 18:04:19 -0400
In a 2005 paper published just weeks before Hurricane Katrina, Kerry Emanuel of MIT said that there appeared to be a statistical link between warmer temperatures and hurricane intensity. Now, using new models of the atmosphere, Emanuel and colleagues say the link may not be so clear after all. - Bush Details 'Right' and 'Wrong' Climate Policy (0mb)
Fri, 18 Apr 2008 18:04:13 -0400
President Bush has announced a new set of national goals related to climate change and called for a stop to growth in greenhouse gas emissions by 2025. Speaking Wednesday in the Rose Garden, he said that "there is a wrong way and a right way to approach reducing greenhouse gas emissions."
