Scientists at CERN, the European nuclear research facility, say they have produced and trapped molecules of antihydrogen, a form of antimatter. Physicist Jeffrey Hangst explains how they were made and captured. Will trapping antimatter help scientists learn about the construction of the universe?
Kelly Ward, senior software engineer for Walt Disney Animation Studios, was tasked with bringing Rapunzel's locks to life in Disney's new movie, Tangled. The hair had to look realistic, but not too real -- otherwise Rapunzel would be towing 80 pounds of hair behind her.
It's been 75 years since Albert Einstein decried the "spooky action at a distance" of quantum entanglement. Tom Siegfried, editor-in-chief of Science News, explains how quantum mechanics is being put to use, even though scientists still don't quite understand how it works.
Why do humans have consciousness? In his new book, Self Comes To Mind, neurologist Antonio Damasio argues that consciousness gave humans an evolutionary advantage. Damasio describes the differences between self and mind, and traces the evolutionary path of the human brain.
Harvard researchers have developed a Web tool for volunteers to record what they're doing and how they feel while doing it. The goal? To measure happiness. Doctoral student Matt Killingsworth describes some early results suggesting many people aren't "living in the moment."
Subra Suresh, former dean of engineering at MIT, was sworn in last month as director of the National Science Foundation, which doles out billions of dollars for basic research each year. Suresh talks about his priorities and how the NSF's budget is likely to fare with the new Congress.
This week, a group of scientists called the "rapid response team" has promised to speak up about climate change and take skeptics head-on, even if that means participating in political debates. But does this verge on advocacy? And is that a problem? Ira Flatow and guests discuss.
When it comes to comets, gassy is good, or at least informative, says astronomer Michael A'Hearn. NASA's Deep Impact probe has been snapping pictures of Hartley 2 -- a small comet that is spewing a lot of gas and dust for its size. What do researchers hope to learn from the comet?
Lichens grow practically everywhere, but they have been neglected by scientists for years, says James Lendemer, a lichenologist with New York Botanical Garden. Lendemer took Science Friday on a trip to the Tannersville Cranberry Bog in Pennsylvania to explore the diversity of lichens living there.

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.
