Gaps forming in seasonal Arctic sea ice may be creating a toxic conveyor belt, drawing mercury from higher altitudes to rain down on the ice, snow and tundra, according to a new study. The gaps, which come as the region shifts from perennial ice to thinner seasonal ice due to climate change, drive convection currents in the lower atmosphere that cycle mercury and ozone from higher levels toward Earth's surface, where oxidation converts the mercury into a more toxic form, according to the study published online Wednesday in the journal Nature.

Stars had faces in the golden age of Hollywood. And for many years, photographer George Hurrell, the father of the Hollywood glamour portrait, captured their allure, glamour and indefinable charisma. Known as the "Rembrandt of Hollywood," the groundbreaking photographer is the subject of "George Hurrell's Hollywood: Glamour Portraits 1925-1992," a biographical coffee-table book by writer-photographer Mark A. Vieira, who knew Hurrell for more than 15 years. Using interviews, archival documents and 20 years' worth of his own diaries, Vieira creates a portrait of a brilliant, complicated artist who had a great working relationship with the stars and a mercurial personality with studio chiefs.

Mercury levels in women's blood are dropping, and not because they're eating less fish, a new study says. Instead, women appear to be eating smarter and choosing less contaminated varieties of seafood, according to a study released this week by the U.S. Environmental Protection Agency. The analysis showed that blood mercury levels in women of childbearing age dropped by about one-third between 2001 and 2010 compared with 1999 and 2000. "There was very little change in the amount of fish consumed and mercury levels in fish tissue did not decline," said Betsy Southerland, director of the Office of Science and Technology in the EPA's water division.

Opinions about Mercury General Corp. often depend on whether they're coming from investors or consumers. The Los Angeles automobile and homeowner insurance company has been at the center of repeated attempts to amend California's landmark Proposition 103, which made automobile insurance a more regulated industry. For more than a decade, Mercury's founder and chairman, George Joseph, has clashed repeatedly with consumer advocate Harvey Rosenfield, author of the landmark proposition, before the California Department of Insurance, the courts, the Legislature and on the ballot.

The destructive environmental legacy of Gold Rush mining in the Sierra Nevada could last for thousands of years in the form of ongoing erosion of mercury-laced sediments, according to new research. Mercury, a toxic heavy metal, was used in copious amounts in California's hydraulic gold mining operations in the mid- and late 1800s. Miners blasted gold-bearing sediment out of vast, ancient gravel beds with water cannons. They then added liquid mercury to the slurry, allowing the gold-mercury amalgam to sink to the bottom of troughs.
