The world's most precise clocks can reveal tiny time dilations predicted by Einstein's theory of relativity -- but that's not all. Tom O'Brian of the National Institute for Standards and Technology talks about using these precise clocks in everything from cell phones to satellites.
Humans and chimpanzees share very similar genes -- some analyses peg the differences at just 1 percent. But in his book Almost Chimpanzee, science writer Jon Cohen focuses on our differences, from the way we eat and communicate to our susceptibilities to disease and aging.
Personalized medicine promises to deliver more tailored health care. But what if a person's genes reveal he won't get much benefit from the only available treatment? Ethicist Leonard Fleck discusses the tough decisions Americans face in deciding whether to pay for others' expensive treatments.
Three separate rigs are drilling escape shafts to free the 33 miners trapped half a mile beneath the Atacama desert in Chile. Mine safety advocate Davitt McAteer and drilling engineer Rudy Lyon discuss the technology being used in the rescue and how miners can be kept out of harm's way.
Many police departments use forensic artists to help solve crimes. From composite sketches to facial reconstructions, the work of these artists combines creativity, science and detective skills. Artist Karen T. Taylor and anthropologist Mary Manhein discuss the science behind forensic art.
Stephen Mancusi worked for the New York Police Department for 27 years as a forensic artist. He specializes in composite sketching -- the process of interviewing victims and witnesses to create a drawing of a perpetrator that is released to help police find suspects.

If doctors listen more carefully to patients' conversations about work and family life, they can pick up clues that lead to better treatment, according to a study in the Journal of the American Medical Association. Author Dr. Alan Schwartz talks about training doctors to be better listeners.
Can you remember everything you see when you walk into a room? Why does our memory deceive us, even when we're confident we're paying attention? Psychologists Christopher Chabris and Daniel Simons discuss what grabs our focus, and why.
Just as Charles Lindbergh was tempted to fly nonstop to Paris in hopes of winning a $25,000 prize, the U.S. government is offering millions of dollars in prize money to lure innovators into building better lightbulbs, cheaper satellite-launching spacecraft and more fuel-efficient cars.
New Caledonian crows are among only a handful of species that have been shown to use tools. They use twigs to fish out beetle larvae from dead trees. Reporting in Science, Christian Rutz and colleagues explore why the birds evolved this rare trait.
Environmentalist Bill McKibben was hoping the Obama administration would reinstall a solar panel President Jimmy Carter once had on the White House. McKibben took the panel to Washington, D.C., but administration officials declined to put the panel back on the White House roof.
Using measurements of the cosmic microwave background, researchers say, there’s evidence that galaxy clusters are being pulled along by a force outside the visible universe. Theoretical physicist Michael Turner explains this “dark flow” and other recent cosmology news.
In her new book The Calculus Diaries, writer Jennifer Ouellette describes the development of calculus, from Archimedes to Newton, and shows how calculus is a part of everyday life -- from amusement park rides and Vegas craps tables, to dieting and figuring out gas mileage.
