Mental stimulation and drug treatment may help people with brain ailments such as Alzheimer's disease regain seemingly lost memories, according to research published on Sunday.
Perchlorate, a chemical used in rocket fuel, is turning up in the nation's food -- in vegetables like lettuce and spinach -- and water supply.
On March 13, Brandy Bridges was installing some of the two dozen CFL (compact fluorescent lamp) bulbs she had purchased in an attempt to save money on her energy bill.
One month later, though, Bridges is paying much more than she had ever expected to.

Drinking alcohol increases a woman's risk of developing breast cancer - but smoking has no impact, researchers have found.
Scientists have calculated that a woman's risk of breast cancer rises by 6% for each extra alcoholic drink she consumes on an average daily basis (7% on international measures).

Moderate alcohol consumption, or about two drinks a day, has often been touted as heart healthy in recent years, but a new study finds the same quantity causes cancer.
Mice given the human equivalent of two drinks daily developed breast tumors that were nearly double the weight of those in their "dry" relatives.
Nearly 179,000 U.S. women will develop breast cancer this year, according to the National Cancer Institute. Even so, scientists lack a strong grasp on why one woman develops the disease and another remains cancer free.
Presented here at the American Physiological Society (APS) annual meeting, the research not only shows the link between alcohol consumption and breast cancer, but it proposes how that glass of wine or bottle of beer works to stimulate tumor growth.
"Alcohol [consumption] is the most important avoidable risk factor for women getting breast cancer," lead scientist Jian-Wei Gu of the University of Mississippi Medical Center told LiveScience. Genetic factors would be considered "unavoidable," since people inherit DNA from their parents.

Why do some people get fat even when they eat relatively little? What creates that irresistible urge for a bag of potato chips or a hunk of chocolate cake, as opposed to a nice crisp apple? Can food urges be irresistible?
Physiologists are unraveling the role that your hormones and brain play in urging you to eat more than you should. Some people's hormones may be signaling their brains to send messages like "Eat a lot now," and "Go for the fat and sugar."
Four physiologists will clarify the latest research on the brain's role in obesity, during the symposium, "Obesity and the Central Nervous System." The symposium will take place at the 120th annual meeting of The American Physiological Society (APS), which coincides with Experimental Biology 2007. The session will be held at 10:30 a.m., Monday, April 30 in Room 146B of the Washington Convention Center and is cosponsored by the London-based Journal of Physiology.

Increasing intake of antioxidant-rich cherries may help lower the risk of metabolic syndrome and cardiovascular disease, suggests a new study(1) presented today at the Experimental Biology annual meeting.
Researchers say the animal study is encouraging and will lead to further clinical studies in humans.
"Metabolic syndrome is a cluster of traits that can greatly increase your risk of heart disease, stroke and Type 2 diabetes, so it's a serious condition that significantly affects public health," said study co-author Dr. Steven F. Bolling, a cardiac surgeon at the University of Michigan Cardiovascular Center who also heads the U-M Cardioprotection Research Laboratory, where the study was performed. "Lifestyle changes have been shown to lower the odds of developing metabolic syndrome, and there is tremendous interest in studying the impact of particular foods that are rich in antioxidants, such as cherries."
Metabolic syndrome (also called insulin resistance syndrome) has become increasingly common in the United States, especially among adults in their mid-30s.

A new study to be presented at the American Academy of Neurology's 59th Annual Meeting -- which begins next week in Boston -- found that people who are taking anti-depressant medications are more likely to develop Parkinson's disease than people who are not taking the medications.
Researchers said that in the year before their Parkinson's disease was diagnosed, people who were taking anti-depressants were nearly twice as likely to develop Parkinson's disease as those who were not taking anti-depressants, the Harvard School of Public Health said in a release.

Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows.
The research, which was conducted on rats, suggests that the human brain may be more adept at distinguishing smells than previously thought. The work comes from studies in the laboratory of Leslie Kay, Assistant Professor in Psychology at the University, who is looking at the ways animals perceive sensory stimuli by focusing on the neural basis of olfactory perception and how context and experience influence it.
The research demonstrates the importance of smell as a means for people to gather information from their environment. Smell is often an undervalued sense because people are more aware of the visual aspects of their perceptions, the researchers said.
Those visual distractions lead people to ignore their ability to detect smells, something the brain is apparently well equipped to do, according to Kay and Jennifer Beshel, a graduate student at the University, who presented results of her dissertation research in the talk, "Olfactory bulb gamma oscillations are dynamically altered to adjust to task demands," at the annual meeting of the Association for Chemoreception Sciences in Sarasota, Florida.
