New research suggests that seniors who did mentally stimulating activities such as crossword puzzles postponed the loss of thinking skills, but had an accelerated rate of decline once dementia set in later in life. Neuropsychologist Robert S. Wilson explains the finding.
Reporting in the Proceedings of the National Academy of Sciences, researchers describe a new predatory dinosaur from the late Cretaceous period in Europe. Balaur bondoc (Romanian for "stocky dragon") is huskier than its relative the Velociraptor.
Reporting in the journal PLoS ONE, researchers write that organically grown strawberries contain more antioxidants and vitamin C than conventional berries. Ira Flatow and guests discuss the findings, and whether the differences would have any meaningful impact on Americans' health.
Clifford Nass, a communications professor at Stanford University, has been studying the ways humans interact with computers to tease out some of the intricacies of how people relate to each other. He talks about those findings in his new book The Man Who Lied to His Laptop.

A federal judge has blocked President Obama's 2009 executive order expanding embryonic stem cell research. U.S. Rep. Diana DeGett (D-Colo.) and stem cell researcher Rudolph Jaenisch discuss the ruling's impact on scientists, and whether Congress can pass stem cell legislation.
Construction is now under way on the world's biggest wind farm in California's Mojave Desert. Federal and state regulators have given the green light to several large solar thermal projects in the Mojave as well. Ira Flatow and guests discuss the future of clean energy in the U.S.
With daily reports of bedbugs in movie theaters and clothing stores -- let alone apartment buildings -- bedbug hysteria seems to be reaching new heights. Psychologist Kevin Ochsner studies how people regulate emotion and shares tips for how to get your bedbug fear under control.
The future as imagined in science fiction sometimes becomes a reality. Michael and Denise Okuda, graphic designers for Star Trek, and John Underkoffler, science adviser on Minority Report , talk about envisioning the future.
Researchers reporting in the journal Science say they have discovered a new species of oil-eating bacteria living half a mile down in the Gulf of Mexico. Study author Terry Hazen discusses the finding and what these bacteria might mean for future oil spills.
There are hundreds of receptors in the human nose that can pick up thousands of odors with each sniff. But how do we make sense of the scents? Smell researchers Stuart Firestein and Donald Wilson discuss the complexities of olfaction and how the brain sorts out what the nose picks up.
Scientists say images taken by the Lunar Reconnaissance Orbiter, which has been circling the moon for more than a year, show that the moon contracted about a billion years ago, relatively recently in geologic time. Space scientist Thomas Watters describes the lunar images.
Some scientists say they're being locked out of research on the oil spill because they refuse to sign confidentiality agreements. Ira Flatow and guests discuss the problems of doing scientific research when a lawsuit is pending. Is there a way to keep science independent?
Researchers say a type of meditation called integrative mind-body training can strengthen connections in certain areas of the brain, even when practiced for as little as 11 hours. Psychologist Michael Posner describes the study, and explains the brain changes he documented.
Tiny pieces of plastic are aggregating hundreds of miles offshore in concentrations equivalent to those in the "Great Pacific Garbage Patch," according to a Science study. Oceanographer and study author Kara Lavender Law talks about the new questions the study raises.
