Marine biologist Dan Madigan stood on a dock in San Diego and considered some freshly caught Pacific bluefin tuna. The fish had managed to swim 5,000 miles from their spawning grounds near Japan to California's shores, only to end up the catch of local fishermen. It was August 2011, five months since a magnitude 9 earthquake and tsunami had struck in Japan, crippling the Fukushima Daiichi power plant. Madigan couldn't stop thinking about pictures he'd seen on TV of Japanese emergency crews dumping radioactive water from the failing reactors into the Pacific Ocean.

These days, thanks to advances in treatment and detection, millions of women survive breast cancer.   But surviving the disease doesn't necessarily mean the entire battle is over, a population-based study of breast cancer survivors in Sweden and Denmark, published Wednesday in the New England Journal of Medicine , seems to suggest. Assessing a total of 2,168 women whose breast cancer was treated with radiation therapy between 1958 and 2001, a team of researchers found that women's chances of having a major coronary event - a heart attack, bypass surgery or heart disease death - rose in proportion with the radiation dose they received, even at the lower doses of radiation delivered in newer treatments.

A pair of NASA probes has discovered a previously unknown ring of radiation blanketing the Earth, upending a long-standing scientific theory about how charged particles coalesce around the planet, scientists reported Thursday. Just four days after the twin Radiation Belt Storm Probes were launched in August, NASA scientists looked on in amazement as instruments revealed a third belt of high-energy particles between the planet's inner and outer radiation belts, known as the Van Allen belts.

The Transportation Security Administration is removing controversial full-body scanners made by a Torrance manufacturer, winning praise from privacy advocates and passenger-rights groups that raised questions about the health effects of the devices. Rapiscan, a unit of OSI Systems Inc., manufactured about 200 full-body scanners used by the TSA to screen passengers for hidden weapons at airports across the country. The machines generated a storm of protest because the devices use low levels of radiation to create what resembles a nude image of screened passengers.

Elwood Jensen, a medical researcher whose ground-breaking work in the field of endocrinology and breast cancer led to revolutionary and life-saving treatments, died of complications from pneumonia on Dec. 16 in suburban Cincinnati, the University of Cincinnati announced. He was 92. He was repeatedly nominated for the Nobel Prize for his discovery of hormone receptors while at the University of Chicago in the 1950s and 1960s. At Chicago, Jensen focused on the impact that breast tissue had on estrogen while most other researchers analyzed how the hormone influenced tissue.

Astronauts on a future mission to Mars could survive radiation levels on the Red Planet's surface, according to a NASA expert. At a recent press briefing, the scientist in charge of monitoring radiation data collected by the Curiosity Mars rover said energy levels on the planet's surface fluctuate with time of day and the season but are roughly equivalent to what astronauts experience now in the International Space Station. "Absolutely,  astronauts can live in this environment," said Don Hassler, of Boulder, Colo.'s, Southwest Research Institute.

Wallace L.W. Sargent, a Caltech astrophysicist known for his observations of black holes, quasars and other celestial objects at the farthest reaches of the universe, died Oct. 29 at the USC Norris Comprehensive Cancer Center in Los Angeles, according to a Caltech spokesman. He was 77 and had been battling prostate cancer. A professor emeritus of astronomy, Sargent arrived at Caltech from his native Britain in 1959 and spent three years as a research fellow. He returned to the university in 1966 as an assistant professor and became a full professor in 1971.

If you're still skeptical that a tan can be dangerous, consider this: Scientists have found that wild fish are getting skin cancer from ultraviolet radiation. Approximately 15% of coral trout inAustralia'sGreat Barrier Reef had cancerous lesions on their scales. In that regard, they resemble Australians who live on land - 2 in 3 people who live down under will be diagnosed with skin cancer before the age of 70, the highest rate in the world. It's probably no coincidence that Australia is under the Earth's biggest hole in the ozone layer.

The sun does lots of cool stuff. We couldn't live on Earth without it. But the havoc it wreaks with our skin is not so hot. The culprit is ultraviolet, or UV, radiation, which can actually be very useful in fluorescent lighting and sterilizing medical equipment, or by stimulating our bodies to make vitamin D. But a little goes a long way, and overexposure to UV radiation is a major cause of skin cancer. (It's classified as a human carcinogen by the U.S. Department of Health and Human Services and the World Health Organization.)

The U.S. Federal Communications Commission plans to ask whether its standards protect humans from mobile-phone radiation, a question it hasn't posed in 15 years, as people use smartphones for longer, more frequent calls. Julius Genachowski, the agency's chairman, is to ask fellow commissioners today to approve a notice commencing a formal inquiry, Tammy Sun, a spokeswoman for the agency, said in an emailed statement. The notice won't propose rules, Sun said. "Our action today is a routine review of our standards," Sun said.
