Researchers defended animal testing at a recent AAAS meeting, saying that not doing animal research would be unethical and cost human lives. The team told symposium at the annual meeting of the American Association for the Advancement of Science (AAAS) that testing on animals has led to "dramatic developments in research that have improved and affected the quality of human life." "To not do animal testing would mean that we would not be able to bring treatments and interventions and cures in...

By Adam Voiland, NASA's Earth Science News Team An assessment report to be released this week by the United Nations Environment Program and the World Meteorological Organization shows that reducing emissions of two common air pollutants -- black carbon and gases integral to the production of ground-level ozone -- could slow the rate of climate change markedly over the next half-century. For decades, scientists have known both substances harm human health. More recently, evidence has emerged...

A group of chemical compounds used by a species of tropical seaweed to ward off fungus attacks may have promising antimalarial properties for humans. The compounds are part of a unique chemical signaling system that seaweeds use to battle enemies "“ and that may provide a wealth of potential new pharmaceutical compounds. Using a novel analytical process, researchers at the Georgia Institute of Technology found that the complex antifungal molecules are not distributed evenly across the...

Experts are warning of solar storms that could thrust our planet into chaos by disrupting computer activity and telecommunication systems on an international scale. Speaking at the annual American Association for the Advancement of Science (AAAS) meeting in Washington DC over the weekend, UK Chief Scientific Advisor John Beddington said that the "issue of space weather has got to be taken seriously." "We've had a relatively quiet [period] in space weather and we can expect that quiet period...

Researchers at the University of Michigan and Penn State University have been studying a species of shape-changing plant that they believe can help them develop a new breed of structures that can twist, turn, bend, stiffen, and otherwise adapt to their environments. According to a press release from the Ann Arbor, Michigan-based educational institution, the Mimosa plant, which folds its leaves on contact through a phenomenon known as nastic motions, could result in robots that could maneuver...

Once regarded as the stuff of science fiction, antimatter"”the mirror image of the ordinary matter in our observable universe"”is now the focus of laboratory studies around the world. While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates""”or disappears in a flash of gamma...

Seven billion: that is the estimated number of people the United Nations predicts will be alive on the planet this year, and climbing to a possible nine billion by 2050, John Bongaarts of the non-profit Population Council said at the annual American Association for the Advancement of Science meeting. A more affluent and growing population will compete for ever scarcer resources and could make for an "unrecognizable" world by 2050, researchers warned. To feed all those mouths, "we will need...

Bill Chaplin from the University of Birmingham, speaking at the American Association for the Advancement of Science (AAAS) conference in Washington, said that the Kepler space telescope was an exquisite tool for what is called "astroseismology", measuring the sizes and ages of stars. The Kepler telescope measures five times better than any other means as it "listens" to the sounds they make. The technique, used to measure some 500 far-flung stars, measures minuscule variations in a...

Scientific community able to police itself, noted physicist asserts The global scientific community is capable of policing its own behavior and should resist creation of a central oversight body to enforce 'universal standards' that may have unintended consequences, a renowned physicist and director of the Energy Institute at the University of Texas at Austin said Saturday. Speaking at the American Association for the Advancement of Science (AAAS) Science Without Borders meeting in...

US scientists, speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington Saturday, said climate change could increase exposure to water-borne diseases originating in the world's oceans, lakes and coastal ecosystems, adding that the impact will most likely be felt within the next 30 years, and as early as the next 10 years. Numerous studies have shown that shifts from climate change make ocean and freshwater ecosystems more susceptible to...

Science is a weekly peer-reviewed academic journal of the American Association for the Advancement of Science (AAAS). It was founded by New York journalist John Michaels in 1880 with financial support from Thomas Edison and later from Alexander Graham Bell. Because of limited success the journal ceased publication in March 1882, only to be reestablished a year later by entomologist Samuel H. Scudder who was able to keep the journal going until 1894, when it was sold to psychologist James...
