Biochemists at The University of Texas Medical School at Houston say the day may be coming when scientists will be able to fine tune enzymes responsible for flavors in fruits and vegetables. In addition, it could lead to environmentally-friendly pest control. view more (2008-08-21)
Scientists Conduct Shark Survey off U.S. East Coast

Geomagnetic field is necessary for health
The consequences of isolation from natural geomagnetic field have been investigated via experiments with salmon fry by Oleg Zaporozhets, Doctor of Biology, Kamchatka Research Institute of Fish Industry And Oceanography. Salmon fry raised for release into rivers are kept in large pools. Fish survival and growth rate depend on diverse factors: pool... view more... (2003-07-18)
First 'mainly vegetarian' spider described

Brown tree snake could mean Guam will lose more than its birds
In the last 60 years, brown tree snakes have become the embodiment of the bad things that can happen when invasive species are introduced in places where they have few predators. Unchecked for many years, the snakes caused the extinction of nearly every native bird species on the Pacific island of Guam. view more (2008-08-11)
Microbes compete with animals for food by making it stink
Microbes may compete with large animal scavengers by producing repugnant chemicals that deter higher species from consuming valuable food resources - such as decaying meat, seeds and fruit, a new study suggests. view more (2006-11-02)
Discovery of a water snake that startles fish in a way that makes them flee into its jaws
