TORONTO - In an effort to reduce energy costs and greenhouse gas emissions,  The Hospital for Sick Children Atrium in Toronto is installing a new solar panel system on the roof. The solar energy system will supplement the hospital's hot water system, providing an environmentally friendly method to reduce energy costs and increase savings for the hospital. Ninety-two collectors, also know as solar panels, are being installed on SickKids' roof, along with 480 gallons of storage volume. The collectors are fixed to the roof on pre-engineered racks that are bolted to the roof below.

CHICAGO - The Great Lakes Legacy Act cleanup of Tannery Bay on St. Marys River in Sault Ste. Marie, Mich., is complete. U.S. Environmental Protection Agency, Phelps Dodge and Michigan Department of Environmental Quality have finished dredging 44,000 cubic yards of contaminated sediment from the bay. St. Marys River is the connecting channel between lakes Superior and Huron.

The report, based mainly on Census Bureau data, showed that most of these uninsured individuals lacked coverage for lengthy periods of time: nearly two- thirds (63.9 percent) were uninsured for six months or more; and over half (50.2 percent) were uninsured for nine months or more.

The major drivers of market growth are the mainstreaming of natural & organic cosmetics, inward investment and growing consumer demand for green products. Distribution of natural and organic cosmetics is increasing in supermarkets, drugstores, and pharmacies across North America and Western Europe. Investment is coming in from large cosmetic manufacturers, retailers, private and financial investors.

NEW YORK (Reuters Health) - Regular exercise may work as well as medication in improving symptoms of major depression, researchers have found.

In a study of 202 depressed adults, investigators found that those who went through group-based exercise therapy did as well as those treated with an antidepressant drug. A third group that performed home-based exercise also improved, though to a lesser degree.

Importantly, the researchers found, all three groups did better than a fourth group given a placebo -- an inactive pill identical to the antidepressant.

NEW YORK (Reuters Health) - Older women who drink two or more alcoholic beverages a day may have an elevated risk of endometrial cancer, a new study suggests.

Endometrial cancer begins in the lining of the uterus, and certain factors that raise a woman's lifetime exposure to estrogen are thought to contribute to the disease. Obesity, late menopause and early menarche (the beginning of menstruation) have been linked to a heightened risk of endometrial cancer.

WASHINGTON (Reuters) - Stem cells that normally make sperm can be taught to make other tissues as well, perhaps offering men a medical repair kit, U.S. researchers said on Wednesday.

They found a way to easily pick the cells out from other tissue in the testicles and to grow them into batches big enough to use medically.

This provides a new source of stem cells, the body's master cells, which experts hope can be used to treat injuries, replace diseased tissue and perhaps even regenerate organs.

WASHINGTON (Reuters) - Assuming you read at average speed, by the time you get to the bottom of this column, the war in Iraq will have cost the United States another $760,000. More than $4 million of U.S. taxpayers' money ebbed away in the 18 minutes it took George W. Bush to explain to his country and the world last week why the war he ordered would last well beyond his presidency.

Now, in the first study of its kind, published in the current issue of the journal Genome Biology, UCLA researchers have identified a distinct pattern of gene expression in immune cells from people who experience chronically high levels of loneliness. The findings suggest that feelings of social isolation are linked to alterations in the activity of genes that drive inflammation, the first response of the immune system. The study provides a molecular framework for understanding why social factors are linked to an increased risk of heart disease, viral infections and cancer.
