ARSENIC AND RICE After a study revealed “worrisome” levels of arsenic in most rice products surveyed, consumer groups are calling for federal regulation. The Food and Drug Administration says that it has found no evidence that rice is unsafe to eat but that it is in the middle of a new study of 1,200 grocery-store rice products to measure arsenic levels. [San Jose Mercury News] FRENCH STUDY LINKS GMO CORN AND RAT TUMORS French scientists say rats fed genetically modified corn sold by Monsanto suffered tumors and kidney and liver damage, among other complications.

All along the rice shelf at the grocery store, where brown and white rice sit alongside rice-based breakfast cereals, rice pastas, rice drinks and rice crackers, there's arsenic, and often at troubling levels. The new findings from a Consumer Reports investigation show “significant” and “worrisome” amounts of inorganic arsenic in nearly every rice product tested. The watchdog group urged consumers to scale back ingestion of rice products and asked the Food and Drug Administration to set limits.

In a long awaited but hardly unanticipated development, two teams of scientists reported Sunday that a strange bacterium called GFAJ-1, once reported to use arsenic instead of phosphorus in its cellular machinery, requires phosphorus to grow after all - just like every other organism on Earth. The microbe “is still a phosphate-dependent bacterium,” one of the research teams wrote in the journal Science. The two groups' research papers may put to rest a debate that began in December 2010 when a group of scientists, including a NASA-affiliated researcher named Felisa Wolfe-Simon, announced a jaw-dropping discovery that a strange bacterium they had discovered in California's Mono Lake seemed to use arsenic in its cellular machinery instead of phosphorus.

Worrisome levels of arsenic have been found in two infant formulas that contain organic brown rice syrup as a main ingredient, researchers reported Thursday. Arsenic was also found in some cereal bars that contain organic brown rice syrup. The toxic element is a known contaminate found in rice because the crop absorbs arsenic from soil. According to the authors of the study, from Dartmouth College, the type found in the food products has been identified as a human carcinogen. Arsenic can also cause skin, lung and intestinal irritation as well as miscarriage and infertility.

Finally, some sanity regarding smokestack emissions. After decades of political squabbling, on Wednesday the U.S. Environmental Protection Agency issued its Mercury and Air Toxics Standards, or MATS, which will dramatically cut the amount of highly toxic mercury and about 70 other pollutants released in the United States. The rules target the emissions from coal-fired power plants. Mercury is the key element addressed by these rules, but it's only one of many chemicals -- plus fine particulate matter, which plays a role in asthma and other respiratory illnesses nationwide -- that are regulated by MATS.

Arsenic levels in some commercial fruit juices may be higher than expected, finds a study from Consumer Reports. The discovery comes just months after television host Dr. Mehmet Oz proclaimed results from his own investigation showed that arsenic levels in apple juice were unhealthful. The Food and Drug Administration claimed Oz's statistics were faulty and said juice was safe to drink. Apple juice contains a certain amount of organic arsenic, and what Oz found, they said, represented the total amount of arsenic and wasn't an accurate reading.

An apple a day may keep the doctor away, but apple juice? That's asking for trouble. Witness the white-hot flames of controversy this week over Dr. Mehmet Oz's claims that apple juice contains unhealthful levels of arsenic. Here's the background in a nutshell: On his syndicated television show, Oz made the claims about apple juice containing arsenic, which prompted the Food and Drug Administration and others to fire back, saying that Oz's claims were unfounded and that the juice was safe to drink.

Arsenic, chicken feed and the FDA are three terms not normally seen together in health articles. Here’s how such an alignment can happen… An arsenic-containing drug used in chicken feed will no longer be sold in the U.S. after FDA researchers detected a more dangerous form of arsenic in chickens fed the chemical. The agency announced Wednesday that Pfizer subsidiary Alpharma will discontinue U.S. sales of 3-Nitro, a drug fed to chickens...

The stage was set by a coy news release from NASA that hinted at a discovery tied to the search for extraterrestrial life. The blogosphere went wild: Had bacteria been found on one of Saturn's moons, or life of some sort on Mars? FOR THE RECORD: Mono Lake bacteria: A Dec. 23 article in Section A about a bacteria from Mono Lake that may be able to survive on the toxic element arsenic quoted Harry Collins, who studies the sociology of scientific knowledge at the University of Cardiff, and said that the university is in England.

Last week, amid much fanfare, scientists reported they had found an organism that ? unlike all previously observed life on Earth ? was able to do without phosphorus and use the normally deadly element arsenic in its place. This week, skeptical scientists expressed serious concerns about the discovery and the researchers' interpretation of their experimental results. "There must be a hundred things in that paper that have people going, 'Hey, wait, that can't be right,'" said Rosie Redfield, a microbiologist and professor of zoology at the University of British Columbia who kicked off the widespread criticism with a blog post last Saturday.
