Children are more radio-sensitive than adults and children undergoing CT scans have triple the risk of leukemia and brain cancer after two or three CT scans according to a recent article in the Lancet. Doctors think the benefits usually outweigh their risks, but "radiation is known to carry a hard-to-calculate, elevated, long-term probability of induced cancers", according to Marta Hernanz-Schulman, MD, chair of the American College of Radiology Pediatric Imaging Commission.

Alex Baer: As Far Out as Uplifting Moments Can Go
First, the news: Fans of sci-fi and science fact are coming up on a special moment: knowing an object of human origin is about to move into interstellar space.
Nearly 35 years after launch, two Voyager spacecraft, sent aloft less than three weeks apart, in the summer of 1977, are thrumming along fine, and continue to send back intriguing accounts of their journeys.
Shock study: Chemotherapy can backfire, make cancer worse by triggering tumor growth
Long considered the most effective cancer-fighting treatment, chemotherapy may actually make cancer worse, according to a shocking new study. The extremely aggressive therapy, which kills both cancerous and healthy cells indiscriminately, can cause healthy cells to secrete a protein that sustains tumor growth and resistance to further treatment.
Researchers in the United States made the "completely unexpected" finding while seeking to explain why cancer cells are so resilient inside the human body when they are easy to kill in the lab.
Thousands of fish are dying in dried-up waterways
Thousands of fish are dying in the Midwest as the hot, dry summer dries up rivers and causes water temperatures to climb in some spots to nearly 100 degrees.
Biologists in Illinois said the hot weather has killed tens of thousands of large- and smallmouth bass and channel catfish and is threatening the population of the greater redhorse fish, a state-endangered species.
Keystone XL pipeline may threaten aquifer that irrigates much of the central U.S.
James Goecke is a counterpoint to Kleeb. A hydrogeologist and professor emeritus at the University of Nebraska in Lincoln, he has been measuring water tables in Nebraska’s ecologically sensitive Sand Hills region since 1970 and has shunned the political limelight — until now. He recently appeared in an ad for the pipeline’s owner, TransCanada, rebutting some of the arguments against the project and its new route.
The Bombs of August : In Remembrance of Hiroshima and Nagasaki
The crew of the B-29 was so young and heroic, and in the photo they also looked very happy. For some reason, I clearly remember the name of the pilot, Paul Tibbets. Of course I remember the name of the plane, the Enola Gay. And oh yes, I remember the name of the bomb. It was called Little Boy. That made me smile.
Roswell UFO Crash: There Were 2 Crashes, Not 1, Says Ex-Air Force Official
The 1947 UFO controversy of Roswell, N.M. is like a bad penny: It keeps turning up. The legend, rehashed by conspiracy theorists in countless documentaries, revolves around allegations that an unusual object fell from the sky -- an object so bizarre that the U.S. Air Force issued a press release that a flying saucer had crashed.
That story was quickly recanted, creating what would become one of the greatest urban legends in American history.
Alex Baer: All This Underwear, All These Twists
There was the usual chit-chat first -- checking the temp on club members' relationships, jabbering a drizzle of baseball, tallying injuries from any DIY jobs, and finding out where everyone else's job search was pegged for the week on the Barf-O-Meter.
