Hospitals are now able to ensure that the correct dose is administered to the 670,000 patients that undergo nuclear medicine procedures every year due to a new device developed by scientists at the National Physical Laboratory (NPL).

Laborers happily scrap "toxic" ship

After over a year of protests by environmentalists, poor workers in west India have happily begun dismantling a controversial cruise liner, ignoring potentially serious risks to their health. The breaking of the 46,000-ton Blue Lady was given the go-ahead by India's Supreme Court last month after a long-running legal battle led by environmentalists, who said the Norwegian ship contained 900 tons of toxic waste like asbestos.

USDA Salmonella Alert On Some Turkey, Chicken Pot Pies
October 9, 2007 08:54 PM -

WASHINGTON (Reuters) - Americans should refrain from eating some turkey and chicken pot pies because they may be linked to reported cases of salmonella, a food-borne illness, the U.S. Agriculture Department said on Tuesday.

The USDA's public health alert applied to Banquet brand turkey and chicken pot pies and store-brand not-ready-to-eat pot pies with "P-9" printed on the side of the package, said USDA's Food Safety and Inspection Service.

FSIS said it was investigating a Missouri establishment that voluntarily ceased operations on Tuesday "due to reported illnesses linked to their products." FSIS said it conferred over the weekend with public health officials, who said their work suggested a meat product was a potential source of contamination. FSIS sent investigators to the plant on Monday.

Low-fat diet cuts ovarian cancer risk: study

WASHINGTON (Reuters) - A low-fat diet may protect women from ovarian cancer, U.S. researchers said on Tuesday.

Researchers tracked about 49,000 post-menopausal women from around the United States for about eight years. About 40 percent of them were asked to cut nearly in half the amount of fat in their diet. The others were asked to eat their usual diet.

No difference was seen in ovarian cancer risk in the first four years of the study. But in the final four years, the women who ate a diet lower in fat were 40 percent less likely to develop this cancer than the other women, the study found.

Widespread weight loss may reap health benefits
October 9, 2007 06:22 PM -

NEW YORK (Reuters Health) - If a large swath of the population cut down on calories and took up exercise, the resulting health benefits could be extensive, a new study suggests.

The findings are based on an analysis of the economic crisis in Cuba from 1989 to 2000. While the circumstances were dire, and Cuban citizens' health suffered in certain ways, researchers found that significant health benefits also emerged.

Specifically, people's overall calorie intake declined, while their physical activity levels climbed -- mainly as a result of walking or biking instead of paying for public transportation.

Shopping cart goes high-tech
October 9, 2007 05:34 PM -

LONDON (Reuters) - Supermarket shoppers may soon be cruising the aisles with "intelligent" shopping carts that warn them if they're buying too much junk food, technology experts say.

While many would be happy enough if they could simply get their trolley to go in a straight line, the high-tech model will be fitted with a computer screen and barcode scanner.

It will read each product's individual code to give customers information about calories, nutrition, ethical sourcing and the environment.

National Mall To Test "Green" Lawn Care
October 9, 2007 04:57 PM -

WASHINGTON, D.C. — Attempting to prove to the nation that organic lawn care techniques are safe and effective, one of the highest profile lawns in the world is about to try a massive 'green' makeover.

The two-week project involves plowing a section of existing lawn at the National Mall in Washington, D.C., adding compost, other natural soil amendments and fertilizers before reseeding the area. The project was organized by SafeLawns.org. Representatives from the natural lawn care company will return to the Nation’s Capitol frequently in the next two years to continue an organic maintenance program on the area that measures more than four acres.

Study: Bad Relationship Can Cause Heart Attack

LONDON (Reuters) - It has been the stuff of great romantic novels and blockbuster films. Doctors have long suspected it. A study of 9,000 British civil servants has at last established it is possible to die of a 'broken heart'.

The study, reported in the Archives of Internal Medicine, found the stress and anxiety of hostile, angry relationships can boost the risk of developing heart disease. Chances of a heart attack or chest pain rose by 34 percent compared to people on good terms with a spouse or partner.

"A person's heart condition seems to be influenced by negative intimate relationships," researchers wrote. "We showed that the negative aspects of close relationships...are associated with coronary heart disease."

New Study Shows Genetically Engineered Corn Could Pollute Aquatic Ecosystems
October 8, 2007 06:56 PM -

BLOOMINGTON, Ind. -- A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published this week by the journal Proceedings of the National Academies of Sciences.

Researchers, including Todd V. Royer, an assistant professor in the IU School of Public and Environmental Affairs, established that pollen and other plant parts containing toxins from genetically engineered Bt corn are washing into streams near cornfields.

They also conducted laboratory trials that found consumption of Bt corn byproducts produced increased mortality and reduced growth in caddisflies, aquatic insects that are related to the pests targeted by the toxin in Bt corn.
