A natural, edible coating could help keep deadly E. coli bacteria and other nasty bugs away from fresh produce, U.S. government scientists at the U.S. Department of Agriculture reported in Journal of Food and Agricultural Chemistry.
Researchers have found a gap between water and a water-repelling surface that can give new insight into the way water and oil separate. By using high-energy X-rays at the ESRF, an international team defined the size and characteristics of this gap. The knowledge of the structure of a hydrophobic interface is important because they are crucial in biological systems, and can give insight in protein folding and stability.
Scientists at UC Irvine have determined that levels of atmospheric methane — an influential greenhouse gas — have stayed nearly flat for the past seven years, which follows a rise that spanned at least two decades.
Researchers at the Texas Agricultural Experiment Station used RNAi to reduce the toxic compound gossypol from cottonseed to a level that is considered safe for consumption, but left the compound in the rest of the plant to ward off insects and disease. Once commercialized, seed from these plants could provide a new, high-protein food available to 500 million people a year.
The periodic table of chemical elements hangs in front of chemistry classrooms worldwide and is an icon for science. Yet much was unknown about its history — until now. The periodic table reflects deep truths about the elements, said Eric Scerri, a UCLA chemist and author of “The Periodic Table: Its Story and Its Significance.”
Underscoring its position as an innovator of many of the most advanced materials technologies in the world, GE Plastics today announced another first: the invention and launch of Extem(1) thermoplastic polyimide (TPI) resins. This new family of highly engineered polymers meets growing OEM demand for easy-to-produce parts that can withstand extreme temperatures and harsh chemicals in the most demanding end-use applications ? in industries such as semiconductor wafer handling, defense, oil & gas processing, aerospace, high-performance fibers, electronics, and automotive.
Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food. Composed of apple puree and oregano oil, which is a natural antibacterial agent, the coating shows promise in laboratory studies of becoming long-lasting alternative to conventional produce washes, according to a team of scientists from the US Department of Agriculture (USDA) and the University of Lleida in Spain.
Renewable resources could produce 25 percent of the electricity and motor vehicle fuels used in the United States by 2025 at little or no additional cost if fossil fuel prices remain high enough and the cost of producing renewable energy continues falling in accord with historical trends, according to a Rand Corp. study issued today. The study was conducted within the Environment, Energy, and Economic Development program of Rand, a nonprofit research organization.
Venom from a West Indian tarantula has been shown to cause pain by exciting the same nerve cells in mice that sense high temperatures and the hot, spicy ingredient in chili peppers, UCSF scientists have discovered.
A Colorado-based company is launching a line of ‘medical- food’ products for the dietary management of asthma, eczema and other allergic conditions based on discoveries by Floyd H. ‘Ski’ Chilton, Ph.D., of Wake Forest University Health Sciences (WFUHS).
