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.
It's back-to-school season and college kids have a lot on their minds: can you compost pizza? What's more sustainable: kegs or cans? Can you have a party with low-flush toilets? Ira Flatow and guests discuss how students and universities are making the college life greener.
Margaret Atwood's new book The Year of the Flood describes a dystopic world full of evil corporations, barbaric criminals and science gone wrong. She talks about the real science in the novel and what can be done to keep her fiction from becoming reality.
Marine biologist Greg Skomal of the Massachusetts Division of Marine Fisheries says the increase in white shark sightings on the East Coast may be due to booming gray seal populations, which lure the sharks closer to shore, as well as bigger crowds on beaches -- meaning more potential...
By the end of 2010, two mass-market electric cars will be rolling on American highways: the Nissan Leaf and the Chevy Volt. The Volt is a gas-electric hybrid, with an all-electric range of 40 miles, and the Leaf is pure electric, with a range of 100 miles. Are Americans ready to plug in?
Plants have a reputation for being sedentary, unmoving, planted. But some plants are moving so quickly, their motion is invisible to human eyes. Biologist Joan Edwards and physicist Dwight Whitaker broke out the high-speed cameras to capture the story of exploding peat moss.
A new study in the journal Nature suggests that the butchering of animals with tools by hominids occurred nearly a million years earlier than thought. Study author Zeresenay Alemseged and anthropologist David DeGusta discuss the finding and what it might mean for human evolution.
The Search for Extraterrestrial Intelligence Institute -- SETI -- turns 25 this year, and it's celebrating with "SETIcon." Participants, including SETI father Frank Drake and the director of the Center for SETI Research, Jill Tarter, discuss the conference and their work.
Although Charles Darwin's tome The Origin of Species is associated with the theory of evolution today, Darwin himself preferred terms such as "transmutation by means of natural selection." Science historian Howard Markel discusses how “evolution“ entered the scientific -- and popular -- vocabulary.
Reporting in Science, researchers write that little brown bats, or Myotis lucifugus, are likely to disappear from the Northeast over the next 16 years. Study author Winifred Frick discusses white-nose syndrome, which is associated with die-offs and caused by a fast-moving fungus.
In Cooking for Geeks: Real Science, Great Hacks, and Good Food, software engineer Jeff Potter discusses using the hacker mindset in the kitchen, from cooking salmon in the dishwasher to a warranty-voiding experiment on his oven to get the scorching temperatures necessary for perfect pizza crust.
Three studies point to receipts as a possibly significant source of the chemical bisphenol-A, according to Science News. While bisphenol-A isn't regulated, the government has suggested minimizing exposure to it. Science News senior editor Janet Raloff discusses the finding.
