Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors.
Fractional quantum state hydrogen can only exists from a relativistic perspective . The Hydrino was dismissed by mainstream physicists because it was defined as having a ground state lower than the Bohr radius.
HAMILTON, Ont. September 11, 2009 -- The smell of recent death or injury that repels living relatives of insects has been identified as a truly ancient signal that functions to avoid disease or predators, biologists have discovered.
CORVALLIS, Ore. -- A large team of researchers has successfully sequenced the entire genome of one of the most famous pathogens in world history - the cause of the Irish potato famine in the 1840s - in work that could ultimately help address a resurgence of this pathogen that is still causing almost $7 billion dollars of agricultural losses around the world every year.
A chemist at the National Institute of Standards and Technology (NIST) has demonstrated a relatively simple, inexpensive method for detecting and measuring elusive hazards such as concealed explosives and toxins, invisible spoilage in food or pesticides distributed in soil by wind and rain.
COLUMBIA, Mo. ?Scientists led a rat to the fatty food, but they couldn't make it eat. Using an animal model of binge eating, University of Missouri researchers discovered that deactivating the basolateral amygdala, a brain region involved in regulating emotion, specifically blocked consumption of a fatty diet. Surprisingly, it had no effect on the rat wanting to look for the food repeatedly.
DALLAS -- Sept. 8, 2009 -- One in five patients with chronic kidney disease is depressed, even before beginning long-term dialysis therapy or developing end-stage renal disease, UT Southwestern Medical Center researchers have found.
UNIVERSITY PARK, PA -- Ozone, the main component of air pollution, or smog, is a highly reactive, colorless gas formed when oxygen reacts with other chemicals. Although ozone pollution is most often associated with outdoor air, the gas also infiltrates indoor environments like homes and offices.
Insects, such as some moths and fruit flies, react to microbial infection in the same way as mammals and so can be used to test the efficiency of new drugs, thereby reducing the need for animal testing.
Novel bacterial strains capable of neutralizing toxins produced by blue-green algae have been identified by researchers at Robert Gordon's University, Aberdeen. Aakash Welgama presented the group's findings during the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh.
Field trials of a new cotton are verifying previous lab and greenhouse studies indicating the crop could become a source of protein for millions of malnourished people in the world.
The cotton was engineered so that the toxic gossypol is reduced to tolerable levels in the high-protein seed but remain at higher levels in the rest of the plant to ward off pests and disease.
Described as cold, heartless, manipulative, selfish, and low anxiety, primary psychopaths frankly scare the bejesus out of most people including myself.
HOUSTON -- (Aug. 31, 2009) -- Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form.
A team of South Korean scientists have succeeded in engineering the bacterium E. coli to produce the industrial chemical putrescine. The research, published in the journal Biotechnology and Bioengineering, provides a renewable alternative to the production of this important chemical which is traditionally created using fossil fuels.
The European Union's REACH (Registration, Evaluation, Authorization and Restriction of Chemical) legislation is intended as a comprehensive safety evaluation for commercial chemicals used in consumer products that are traded in Europe at amounts more than one ton per year.
