Ira Flatow talks with scientists and philosophers about the origins of human values, and the influence of modern scientific thought on human values. Even if science can shape human morals, should it? Or does science bring its own set of preconceptions and prejudices to moral questions?
A new position statement from the American Academy of Neurology includes the recommendation that any athlete suspected of having a concussion be removed from play and evaluated. Neurologist Jeffrey Kutcher describes the new recommendations and the reasons for the changes.
In 1952, scientist Rosalind Franklin took a clear X-ray photo of DNA. Nobel Prize winners Watson and Crick used the image, in part, to determine the double helix -- but did Franklin get the credit she deserved? Actress Kristen Bush and playwright Anna Ziegler discuss a new play on Franklin.
How many people attended Jon Stewart's rally last weekend, or Glenn Beck's rally last summer? It depends on who you ask. Two crowd-counting experts explain the "gold standard" for measuring crowd size, and discuss why some rally organizers might disagree with the counts.
Australian brush turkeys (Alectura lathami) fend for themselves the day they hatch, says Ken Dial of the University of Montana Flight Lab. The birds fly the day they hatch, and hatchlings can climb vertical ledges better than adults, according to Dial's latest research.
In his new book Eels, writer James Prosek describes the life history and cultural significance of this slimy, snake-like and often misunderstood fish, introducing the reader to an eel fisherman on the Delaware River and to the myths of the Maori of New Zealand along the way.
Writing in Nature Medicine, researchers report on discovering bitter taste receptors in human lungs, and that bitter compounds expand airways in asthmatic mice. Stephen Liggett talks about the possibility of treating asthma and chronic obstructive pulmonary disease with bitter compounds.
The cost of sequencing a human genome is plummeting, and soon many people may obtain a copy of their own. But how useful is that information to patients, especially if their genes predict untreatable, fatal diseases? Hank Greely discusses the promise and the pitfalls of genetic testing.
Scientists have long known that cholera is caused by a bacterium transmitted through food or water. But where does the bacterium live between epidemics, and what dictates the timing of new outbreaks? CDC cholera expert Eric Mintz discusses the bacterium behind the Haiti outbreak.
The legend of the ferocious chupacabra, or goat sucker, has circulated around Central America since the 1990s. But the supernatural chimeric beast -- described by some as half dog, half bat -- may just be a coyote suffering from mange, says entomologist Barry OConnor of the University of Michigan.
Scientists excavating an Indian amber deposit say it dates back more than 50 million years, and contains the remains of at least 100 previously undocumented species of insects. American Museum of Natural History curator David Grimaldi describes the amber, and the organisms trapped within it.
Just over a year ago, the LCROSS mission deliberately crashed into a lunar crater, kicking up a cloud of debris --and signs of water. Michael Wargo, NASA's chief lunar scientist, describes other ingredients scientists have identified in lunar soil, a material called regolith.
His personal list of inventions includes everything from an insulin pump to the Segway Transporter. He started the FIRST Robotics engineering challenges for students. Now, inventor Dean Kamen also has his own television show, aimed at spreading the excitement of invention.
Pumpkins of the Atlantic Giant variety can weigh more than 1,800 pounds. For a mechanical engineer with an interest in plus-sized fruit, like Georgia Tech's David Hu, this raises an interesting physics question: How can the pumpkin get so big without breaking?
After a prescription leaves the optometrist's office, how are eyeglasses actually made to order? Larry Enright, general manager of Perferx Optical, talks about the shaping, sanding, polishing, cutting and beveling behind each lens' journey into a pair of finished frames.
