Salmon Farming Threatens Chile's Patagonian Lakes
The production of farmed salmon in Chile's unique Patagonian lakes has doubled in the last decade, contaminating them withnutrient pollution, invasive species, disease and harmful chemicals, according to a new study. Moving farmed salmon from freshwater lakes to land-based closed systems would reduce environmental pressures and increase Chile's competitiveness in the global salmon trade. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Sony PFR-V1 Personal Field Speakers (aka Headphones) Look Cooler Than

A type of bacterium widely found on our skin and in the environment has now become a major threat in hospitals where it can cause serious infections, such as pneumonia in severely ill patients. Like the well known bacterium MRSA (methicillin resistant Staphylococcus aureus) the new types of Acinetobacter baumannii are resistant to nearly all antibiotics, so doctors have very few treatments available, and three resistant strains are currently circulating in the UK.

Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research. Who Went There? Matching Fossil Tracks With Their Makers
Fossilized footprints are relatively common, but figuring out exactly which ancient creature made particular tracks has been a mystery that has long stumped paleontologists. Scientists have now combined their expertise in anatomy and ichnology (the study of tracks) to match up the most common tracks with their makers. Detailed measurements of the tracks, combined with measurements of the legs, feet and backbones of the skeletal material allowed the team to pinpoint the trackmakers. Exercise Plus Gene Therapy Shows Promise For Treating Lou Gehrig's Dis
A new study in mice gives hope that a combination of gene therapy and exercise may extend the lives of people who have Lou Gehrig's disease. Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a chronic and progressive illness that leads to paralysis and ultimately death. There are no known cures, and the only FDA-approved method for treating the disease is a drug that may extend life between three and six months. Plants Defy Mendel's Inheritance Laws, May Prompt Textbook Changes
