Thanks to growing awareness of a national obesity epidemic, and the lowering of complication rates since its introduction in the 1960s, gastric bypass procedures have become an increasingly popular treatment option for the morbidly obese. At least 200,000 people signed up last year in the U.S. alone.
Nano-technology is enabling breakthroughs in a number of scientific fields at an unimaginably small scale. Consider that the basic unit of measurement for nano-particles is 40,000 times smaller than the width of the average human hair. Recently, researchers at MIT and Brigham and Women’s Hospital developed a nano-particle capable of infiltrating the human immune system and delivering a targeted dose of powerful antibiotics.
A special broadcast of NPR's Talk of the Nation: Science Friday host Ira Flatow, recorded in front of a live audience at the University of New Hampshire in Durham.
In part one, Flatow talks about the declining state of science coverage in the news, and his hope that new media will be the new outlet for spreading the gospel of science. In part two, I sit down with Flatow and we talk about his career, the challenges of expanding online platforms, and address questions form the audience.
All that "40 is the new 30" boosterism aside, midlife is not the start of a downward spiral. David Bainbridge is a clinical veterinary anatomist at Cambridge University, and the author of several books including Middle Age: A Natural History. He believes middle age might be a pivotal part of the human evolutionary process, and potentially the most productive years of our lives.
Pulitzer Prize Winning Socio-biologist, E.O. Wilson has spent a lifetime exploring the ideas of evolution and the genetic basis for social behavior in humans. In his latest book, "The Social Conquest of Earth", Wilson overturns his earlier theory on why our species developed strong social ties. Group selection, Wilson now says, not kin selection is the primary driving force of human evolution
E.O. Wilson - Biologist, naturalist and author of more than 20 book. His latest is called "The Social Conquest of Earth"
We sit down with Oxford professor Bryan Sikes whose new book. "DNA U.S.A." explores the complicated genetic melting pot of America. The findings are fascinating, southwestern Spanish Catholics with Jewish genes, African DNA in southern whites. Though we are all born with surnames, Sykes says, "those names fragment and mutate with far more regularity than the DNA we inherit”
Every parent hopes to foster a healthy and safe environment for bright and gifted babies… but no amount of exposure to classical music, sign language, or Baby Einstein videos can guarantee your kid will be a genius on the level of Heidi Hankins.
Scientists at the University of Illinois report that they have mapped the physical architecture of the brain with accuracy never before achieved. Their study, published in Brain: A Journal of Neurology is the largest, most comprehensive analysis so far of the brain structures vital to general intelligence –which depends on a remarkably circumscribed neural system – and to specific cognitive functions, like memory, self-control and recognizing speech.
