Nuts Lower Cholesterol, Study Finds
May 24, 2010 09:14 AM - LiveScience Staff

A diet with nuts, including pistachios, significantly lowered total and LDL-cholesterol levels, in addition to triglycerides, a new study found. The finding, published earlier this month in the Archives of Internal Medicine, confirms other evidence that nuts can help reduce the risk of cardiovascular disease, researchers said.

The Great No Fishing Area
May 19, 2010 12:45 PM - Andy Soos, ENN

The National Oceanic and Atmospheric Administration (NOAA) has extended the boundaries of the closed fishing area in the Gulf of Mexico into the northern portion of the loop current as a precautionary measure to ensure that seafood from the Gulf will remain safe for consumers. Though the latest analysis shows that the bulk of the oil remains dozens of miles from the loop current, the new boundaries address the possibility that a tendril of light oil has entered or will enter the loop current. Part of the Gulf Stream, the Loop Current is a warm ocean current in the Gulf of Mexico that flows northward between Cuba and the Yucatan peninsula, moves north into the Gulf of Mexico, loops west and south before exiting to the east through the Florida Straits.

Long-Lasting Sensory Loss in World Trade Center Workers from Airborne Toxins After 9/11 Attacks
May 19, 2010 08:57 AM - Science Daily

New research from the Monell Center and collaborating institutions reports that workers exposed to the complex mixture of toxic airborne chemicals following the 9/11 attacks on the World Trade Center in New York City had a decreased ability to detect odors and irritants two years after the exposure.

Hard Exercise Can Prevent Cell Death
May 14, 2010 10:52 AM - David A Gabel, ENN

Every day our bodies are dying, or rather, our millions of cells are dying. Fortunately they do not all die at once, and there is always another cell to take its place. What if people could stop their cells from dying? Wouldn't that be the same as eternal life? Well that is not possible, so the best people can do is delay the cellular inevitable. To do so merely entails exercise, an activity that people should be doing anyway. An Italian team of scientists at the University of Rome put their collective skills together to prove this hypothesis.

Air Quality Awareness Week Focuses on Reducing Exposure to Ozone, Particle Pollution / Keep your eye on the AQI
May 13, 2010 10:51 AM - US Environmental Protection Agency

WASHINGTON – EPA, state and local air agencies across the country are marking Air Quality Awareness Week by reminding Americans to stay "Air Aware" to reduce their exposure – and their contribution – to air pollution. By following recommendations of the Air Quality Index (AQI), people can take simple steps to reduce the amount of pollution they breathe in. The AQI is EPA’s color-coded tool for reporting daily air quality and forecasts for common air pollutants, including ozone (smog) and particle pollution.

Science Closing in on Mystery of Age-Related Memory Loss, Says UAB Neurobiologist
May 11, 2010 08:38 AM - University of Alabama at Birmingham

BIRMINGHAM, Ala. - The world's scientific community may be one step closer to understanding age-related memory loss, and to developing a drug that might help boost memory. In an editorial published May 7 in Science, J. David Sweatt, Ph.D., chair of the University of Alabama at Birmingham (UAB) Department of Neurobiology, says that drugs known as histone deacetylase inhibitors are showing great promise in stopping memory loss - and even in boosting the formation of memory in animal models.

Stronger evidence pollution damages the heart

The evidence is stronger than ever that pollution from industry, traffic and power generation causes strokes and heart attacks, and people should avoid breathing in smog, the American Heart Association said on Monday. Fine particulate matter from burning fossil fuels such as gasoline, coal and oil is the clearest offender, the group said. "Particulate matter appears to directly increase risk by triggering events in susceptible individuals within hours to days of an increased level of exposure, even among those who otherwise may have been healthy for years," said Dr. Robert Brook of the University of Michigan in Ann Arbor, who headed the group writing the report.

Gaining Weight and Having Type 2 Diabetes
May 10, 2010 01:19 PM - Andy Soos, ENN

Have you ever wondered how can you possibly gain so much weight when somebody else eats even more and gains less? Obviously, some of the answer is how much exercise one does. Another part of the answer is shown in the first study of its type by Australian researchers. Healthy people with a genetic predisposition to Type 2 diabetes gain more weight overeating over the short term than their non-genetically prone counterparts.

Surprising Skin Cancer Risk: Too Much Driving
May 10, 2010 08:52 AM - LiveScience Staff

Long hours behind the wheel may increase the risk of skin cancer, according to a surprising new study. Facial skin cancers were found to occur more often on the left-side — the side that's next to the window while driving — among a group of about 1,050 patients in Saint Louis. The findings were most significant for men. While the results show only an association (not a cause-effect link) and would need to be replicated in a larger population to be viewed as firm, they call attention to what might be overlooked by otherwise sun-conscious citizens — exposure to UV rays through the car window.

Surprising New Diet Tip: Lose Weight Quickly
May 7, 2010 09:18 AM - LiveScience Staff

The key to long-term weight loss and maintenance might be to lose weight quickly rather than gradually, at least in the initial stages of dieting, a new study suggests. More research is needed to determine the best approach, however.
