Science B6 September 25 – October 1, 2008 The Epoch Times National Science Foundation Walnut trees respond to stress by producing significant amounts of a chemical form of aspirin, sci- entists have discovered. The finding, by scientists at the National Center for Atmospheric Research (NCAR) in Boulder, Colo., opens up new avenues of re- search into the behavior of plants and their impacts on air quality, and also has the potential to give farmers an early warning signal about crops that are failing. "Unlike humans, who are ad- vised to take aspirin as a fever sup- pressant, plants have the ability to produce their own mix of aspirin- like chemicals, triggering the formation of proteins that boost their biochemical defenses and re- duce injury," says NCAR scientist Thomas Karl, who led the study. "Our measurements show that sig- nificant amounts of the chemical can be detected in the atmosphere as plants respond to drought, un- seasonable temperatures, or other stresses." For years, scientists have known that plants in a laboratory may produce methyl salicylate, which is a chemical form of acetylsalicylic acid, or aspirin. But researchers had never before detected methyl salicylate in an ecosystem or veri- fied that plants emit the chemical in significant quantities into the atmosphere. The team of scientists reported its findings last week in the journal Biogeoscience. The research was funded by the National Science Foundation (NSF), NCAR's sponsor. "Biosphere-atmosphere interac- tions are important to the under- standing of the Earth system," said Cliff Jacobs, program director in NSF's Division of Atmospheric Sciences. "This fortuitous discov- ery of methyl salicyclate in quan- tities not anticipated adds to an already important study." Researchers had not previously thought to look for methyl sali- cylate in a forest, and the NCAR team found the chemical by ac- cident. They set up specialized instruments last year in a walnut grove near Davis, Calif., to moni- tor plant emissions of certain vola- tile organic compounds (VOCs). These hydrocarbon compounds are important because they can combine with industrial emissions to affect pollution, and they can also influence local climate. When the NCAR scientists reviewed their measurements, they found to their surprise that the emissions of VOCs included me- thyl salicylate. The levels of methyl salicylate emissions increased dramatically when the plants, which were al- ready stressed by a local drought, experienced unseasonably cool nighttime temperatures followed by large daytime temperature increases. Instruments mounted on towers about 100 feet above the ground measured up to 0.025 milligrams of methyl salicylate rising from each square foot of forest per hour. Karl and his colleagues speculate that the methyl salicylate has two functions. One of these is to stimulate plants to begin a proc- ess known as systemic acquired resistance, which is analogous to an immune response in an animal. This helps a plant to both resist and recover from disease. The me- thyl salicylate also may be a mech- anism whereby a stressed plant communicates to neighboring plants, warning them of the threat. Researchers in laboratories have demonstrated that a plant may build up its defenses if it is linked in some way to another plant that is emitting the chemical. Now that the NCAR team has demonstrated that methyl sali- cylate can build up in the atmos- phere above a stressed forest, scientists are speculating that plants may use the chemical to ac- tivate an ecosystem-wide immune response. "These findings show tangible proof that plant-to-plant commu- nication occurs on the ecosystem level," says NCAR scientist Alex Guenther, a co-author of the study. "It appears that plants have the ability to communicate through the atmosphere." The discovery raises the possi- bility that farmers, forest manag- ers, and others may eventually be able to start monitoring plants for early signs of a disease, an insect infestation, or other types of stress. At present, they often do not know if an ecosystem is unhealthy until there are visible indicators, such as dead leaves. "A chemical signal is a very sensitive way to detect plant stress, and it can be an order of mag- nitude more effective than using visual inspections," Karl says. "If you have a sensitive warn- ing signal that you can measure in the air, you can take action much sooner, such as applying pesti- cides. The earlier you detect that something's going on, the more you can benefit in terms of using less pesticides and managing crops better." The discovery also can help scientists resolve a central mystery about VOCs. For years, atmos- pheric chemists have speculated that there are more VOCs in the atmosphere than they have been able to find. Now it appears that some fraction of the missing VOCs may be methyl salicylate and other plant hormones. This finding can help scientists better track the impact of VOCs on the behavior of clouds and the development of ground-level ozone, an important pollutant. WASHINGTON (Reuters)— Health worries about a chemical found in many plastic products have created opportunities for companies catering to the growing market for products made without bisphenol A. But the plastics and food pack- aging industries, which defend the safety of bisphenol A or BPA, argue that particularly for certain uses there are no alternatives that can do everything BPA can do. And they caution that chemicals that may be embraced now as safer alternatives to BPA eventually might turn out to pose their own set of health concerns. Some scientists and activists said a major study published last Tues- day linking BPA to heart disease and diabetes will put more pres- sure on regulators to crack down on the compound. They want BPA banned at a minimum in children's products such as baby bottles. BPA has been used in many products for decades. It is used to make polycarbonate plastic, a transparent, durable, and shatter- resistant material in products including water bottles, plastic utensils, and medical devices. But it can leach out of plastic into liquid such as baby formula, water, or food inside a container. Some retailers, including Wal- Mart and Target, are phasing out products made with BPA. "Large retailers are moving away from BPA products. I think it's going to force manufacturers to switch to BPA-free products only, in feeding [products] or in toys or whatever else you can think of that has BPA," Ron Vigdor, president of Florida-based company BornFree, said in a telephone interview. Vigdor said BornFree has seen big increases in sales of its range of BPA-free products including plas- tic baby bottles and cups made of Polyamide PA, a form of nylon. Nalgene launched a line of water bottles made from a new type of plastic made by Eastman Chemi- cal Company called Tritan copoly- ester, which is not made with BPA but boasts BPA's good qualities such as transparency and shatter resistance. Nalgene is owned by Thermo Fisher Scientific Inc. Spokeswoman Tracy Broad- water said Eastman Chemical is scaling up production capacity for Tritan, introduced last year, with new facilities to be ready by late 2009. Industry officials said the big chemical companies and food package manufacturers are explor- ing alternatives to BPA, but said banning the chemical would be unwise and unwarranted. "An alternative would have to be found that, number one, works, that provides the necessary func- tion. The second big hurdle is that the alternative should be at least as safe," Steven Hentges of the American Chemistry Council industry group said in a telephone interview. BPA makers include Dow Chemical, Bayer, Sunoco Chemi- cals, and Hexion Specialty Chemi- cals, Hentges said. John Rost, chairman of the North American Metal Packaging Alliance, representing the food and beverage packaging industry, said there is no alternative that works as well to prevent spoilage and extend shelf life for canned foods as the epoxy resins made with BPA used as lining in cans. These epoxy coatings became the "gold standard" 25 years ago, replacing an earlier generation of materials. "With the use of epoxy coatings, shelf life of foods virtu- ally doubled overnight," Rost said.

While observing the level of light absorption of these miniscule particles, Ighina became convinced that scientists had made a mistake in conceiving the fundamental struc- ture of atoms. He maintained that it was impossible to study a particle in perpetual motion without creating a false image.

After years of arduous lab work, Ighina discovered the most pro- found nature of matter—that atoms do not oscillate but vibrate. This revelation led to one of his more cu- rious and brilliant inventions—the magnetic field oscillator. The scien- tist discovered that if he managed to change the vibratory state of a group of particles, the material itself could transform. What followed was a series of fan- tastic experiments in which the field oscillator played a leading role. On one occasion, Ighina set up his appa- ratus before an apricot tree. He then altered the atomic vibration so that it gradually became the same as that of an apple tree. (He had previously studied the indices of this vibration.) After 16 days, he ascertained that the apricots had mutated, almost completely, into apples. After this experience, Ighina ven- tured to investigate the reach of his invention on animals. He altered the vibrational state of the tail of a rat to change it, in four days, into the tail of a cat. Even though the rat died after such treatment (perhaps its body was incapable of enduring such a rapid molecular change), it prompted Ighina to try an experiment even more revelatory: Through studying the corresponding vibration of the healthy bone of a rabbit, he excited the atoms of another rabbit’s frac- tured feet until they were healed in record time.
