Bedbugs virtually disappeared from the U.S. by the 1950s, but now they're back -- in homes, hotels and schools. Entomologist Michael Potter, who specializes in pest management, explains how to check hotel rooms for the "perfect parasite" -- and what to do if you suspect an infestation.

Everything you wanted to know about bug sex (but didn't bother to ask) is explained in a new book. Insect expert Marlene Auk describes how ants learn, why some crickets don't chirp and how various bugs mate in Sex on Six Legs: Lessons on Life, Love and Language from the Insect World.

After writing "We Will Rock You" and touring around the world as the lead guitarist in Queen, Brian May made an unusual career choice: He got his Ph.D. in astrophysics. May explains how Queen developed its distinctive sound and explains his fascination with stereoscopic photographs taken in the 1850s.

Doug Inkley, the senior scientist at the National Wildlife Federation, says the population of sea turtles and brown pelicans in the Gulf is being decimated. Inkley details the ongoing efforts to save two of the most visible species affected by the BP oil spill.

Journalist Michael Klare says we've used up what he calls the "easy oil" on Earth. What's left is "tough oil" — deep underground, far offshore or in complex geological formations. Klare details the hazards of drilling in these environmentally hazardous areas in his book, Rising Powers, Shrinking Planet.

The BP disaster has raised questions about the oil industry's ability to manage the risks and challenges involved in drilling thousands of feet below the ocean floor. New York Times science reporter Henry Fountain explains how deep-water drilling is supposed to work — and what may have gone wrong on the Deepwater Horizon.

Entomologist Mark Moffett loves ants. He's devoted his career to studying the tiny insects: how they move, what they eat, when they attack their prey. Moffett's book, Adventures Among Ants, details his explorations around the world, tracking many a species through jungle forests and remote mountain passes.

Ideas that writer Jeff Goodell used to regard as bad science fiction — like launching particles into the stratosphere to reflect sunlight — are now being taken seriously because of global warming concerns. Goodell examines the science behind tinkering with the Earth's climate in his new book, How to Cool the Planet.

Intent on documenting the effects of climate change, nature photographer James Balog ventured into ice-bound regions with 26 time-lapse cameras, which he programmed to shoot a frame every daylight hour for three years.

Nathan Hodge and Sharon Weinberger are nontraditional tourists who explore missile silos, test sites, and bomb shelters. The two just published A Nuclear Family Vacation: Travels in the World of Atomic Weaponry, a chronicle of their travels to nuclear landmarks across ten states and fives countries.
