Insects Develop Resistance To Engineered Crops
Cornell University entomologist Anthony Shelton finds when engineered crops containing just one Bt toxin grow near modified plants with two toxins, insects may more rapidly develop resistance to all the engineered plants. A soil bacterium called Bacillus thuringiensis (Bt), whose genes are inserted into crop plants, such as maize and cotton, creates these toxins that are deadly to insects but harmless to humans. Jan. 25, 1921: The Robot Cometh
Robots have practical use today. But when Karel Capek coined the word, they were just downright creepy. Compiled by Tony Long. Coyote Bytes
Coyote encounters in California are the subject of this website for "homeowners, land managers, agency personnel, and others to help solve coyote-human conflicts, particularly in urban and suburban areas."Report a coyote encounter or check the encounter map covering Los Angeles, Orange, and San Diego counties ("It will be expanded to all of California at a future date"). An image gallery captures coyotes in urban and suburban settings. Funded by the Renewable Resources Extension Act. Instruction Manual For Creating A Molecular Nose
An artificial nose could be a real benefit at times: this kind of biosensor could sniff out poisons, explosives or drugs, for instance. Researchers at the Max Planck Institute for Polymer Research and the Max Planck Institute of Biochemistry recently revealed a technique for integrating membrane proteins into artificial structures. Protein Structure Key For AIDS, Cell Function
Cornell University researchers have discovered the 3-D structure of a protein, human CD38, which may lead to important information about how cells release calcium -- a mineral used in almost every cellular process -- and also may offer insights into mechanisms involved with diseases ranging from leukemia to diabetes and HIV-AIDS. New Standard For Environmentally Friendly Carpet Developed
Don't call it 'green'carpet, call it sustainable carpet. A new standard for assessing the environmental-friendliness of carpet has just been announced. The new sustainability standard, approved by the American National Standards Institute, addresses chemicals and materials used in manufacturing carpet, the energy used in production, the use of recycled or bio-based content, methods of disposal and/or reuse and the overall environmental performance of manufacturers. Cosmetics With Soy Rather Than Petroleum Base Developed
When chemists originally developed SoyScreen, they envisioned outdoor enthusiasts and other consumers using their invention as an environmentally friendly alternative to petroleum-based sunscreens. Instead, SoyScreen became the technological platform from which iSoy Technologies Corporation, began launching a novel class of cosmetic ingredients called "skincare bio-lipid actives." Dust To Gust: Health Of Brazilian Rainforest Depends On Dust From One
More than half of the dust needed for fertilizing the Brazilian rainforest is supplied by a valley in northern Chad, according to an international research team headed by Dr. Ilan Koren of the Institute's Environmental Sciences and Energy Research Department. In a study published recently in Environmental Research Letters, the scientists have explained how the Bodélé valley's unique features might be responsible for making it such a major dust provider. U.S. Environmental Protection Agency (EPA): National Priorities List (
Website for the EPA's "list of national priorities among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States and its territories."On this site "you can locate NPL sites, check their cleanup progress, and get information on new and proposed NPL sites."Details about sites can be viewed through a U.S. map or a database of Superfund sites searchable by numerous factors (such as contaminants). Drug Resistant Avian Influenza Viruses More Common In Southeast Asia T
Resistance to the antiviral drug amantadine is spreading more rapidly among avian influenza viruses of H5N1 subtype in Southeast Asia than in North America, according to the study done by investigators at St. Jude Children's Research Hospital.
