Ozone shuts down early immune response in lungs and body
September 30, 2007 09:09 AM - Duke University Medical Center
As policy makers debate what levels of ozone in the air are safe for humans to breathe, studies in mice are revealing that the inhaled pollutant impairs the body’s first line of defense, making it more susceptible to subsequent foreign invaders, such as bacteria.
Researchers Challenge Assumptions Of GMO Agriculture
September 29, 2007 06:42 PM - Paul Schaefer, ENN
Manhatten, Kansas - A researcher is challenging the assumption that genetically engineered plants are the great scientific and technological revolution in agriculture and the only efficient and cheap way to feed a growing population. They are working on non-GMO methods to accelerate plant breeding. It's called "market-assisted selection". The research is focused on breeding methodology, finding more efficient ways to breed better varieties of corn, sorghum, wheat or barley that yield higher, require less irrigation and are resistant to diseases in farmers' fields. The work was recently published in an edition of the scientific journal Crop Science.
Microbes At Work (Cleaning Up The Environment)
September 29, 2007 06:25 PM -
LIVERMORE, Calif. – It may sound counterintuitive to use a microbial protein to improve water quality. But some bacteria are doing just that to protect themselves from potentially toxic nanoparticles in their own environments, and clean up crews of the future could potentially do the same thing on a larger scale.
A team from Lawrence Livermore National Laboratory, UC Berkeley and Lawrence Berkeley National Laboratory found that bacteria from an abandoned mine excrete proteins that cause metal nanoparticles to aggregate. The bacteria are binding and immobilizing the metals in the nanoparticles and the nanoparticles themselves, which are potentially toxic to the bacteria.
FDA staff urge warnings on kids' cold medicines
September 29, 2007 03:50 PM -
WASHINGTON (Reuters) - Over-the-counter cough and cold medicines that contain decongestants and antihistamines should come with new instructions saying they are not recommended for very young children, U.S. Food and Drug Administration reviewers have recommended.
The FDA has not made a final decision on whether to change the warnings or instructions for use on the widely used drugs, officials said in documents released late on Thursday. The agency will seek input from a panel of outside advisers next month.
Officials said in March they were reviewing use of over-the-counter cough and cold medicines in children. A group of doctors and public health officials had filed a petition voicing concerns that the drugs were risky and not effective for children.

CHICAGO (Reuters) - Topps Meat Company LLC has expanded its recall to include 21.7 million pounds (9,800 tonnes) of ground beef products that may be contaminated with E. coli bacteria, the Elizabeth, New Jersey-based company said on Saturday.
The beef has a "sell by date" or "best if used by date" between September 25, 2007, and September 25, 2008. All recalled products will have a U.S. Department of Agriculture establishment number of EST 9748, which is located on the back panel of the package and/or in the USDA legend.
On Tuesday, the company announced a recall of 331,582 (150 tonnes) pounds of frozen ground beef products.
Study: Replace Older Woodstoves For Indoor Air Quality

Air-quality test results confirm that it’s possible to reduce the concentration of fine particulate matter, which is harmful indoors even at extremely low concentrations, by using cleaner-burning woodstoves certified by the U.S. Environmental Protection Agency (EPA).
Drinking may dampen hearing in the short term
September 28, 2007 05:50 PM -
NEW YORK (Reuters Health) - If you have a hard time hearing conversation at a bar, it may not be because of the noise, a study suggests.
Alcohol, UK researchers found, seems to temporarily drain a person's hearing -- particularly when it comes to discerning the sounds of conversation.
In a study of 30 healthy volunteers, they found that as participants drank, their hearing became less acute. Lower-frequency hearing, which is necessary for discerning speech, suffered the most, the researchers report in the online journal BMC Ear, Nose and Throat Disorders.

NAUTLA, Mexico (Reuters) - Hurricane Lorenzo crashed into Mexico's Gulf coast on Friday, killing three people in a mudslide and knocking out power to 85,000 homes.
In the coastal fishing town of Nautla, Lorenzo's 80 mph (130 kph) winds ripped off bits of roofs, blew down trees and scattered debris in the streets.
"It hit us hard and there is an incredible amount of rain," said Mayra Castro, 29, a waitress who spent the night mopping up water that leaked into her house through windows and under doors.
Corn-based Plastic Packaging Hits The Marketplace

FORT LAUDERDALE, Fla.- A Florida body care company has launched an innovative and earth friendly way to package their products. Their new case, which contains five travel size products, is made entirely from 100% U.S. grown corn, not foreign petroleum. This material is produced from plastic that consists of polylactide, a corn-based versatile polymer.
EPA Orders Five Illinois Feedlots To Halt Stream Discharges
