Wind, solar power paired with storage could be cost-effective way to power grid
Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.
A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. (more…)
New treatment may have fewer side effects than traditional cancer therapy
COLUMBIA, Mo. — Currently, large doses of chemotherapy are required when treating certain forms of cancer, resulting in toxic side effects. The chemicals enter the body and work to destroy or shrink the tumor, but also harm vital organs and drastically affect bodily functions. Now, scientists at the University of Missouri have proven that a new form of prostate cancer treatment that uses radioactive gold nanoparticles, and was developed at MU, is safe to use in dogs. Sandra Axiak-Bechtel, an assistant professor in oncology at the MU College of Veterinary Medicine, says that this is a big step for gold nanoparticle research.
“Proving that gold nanoparticles are safe to use in the treatment of prostate cancer in dogs is a big step toward gaining approval for clinical trials in men,” Axiak-Bechtel said. “Dogs develop prostate cancer naturally in a very similar way as humans, so the gold nanoparticle treatment has a great chance to translate well to human patients.” (more…)
ARMONK, N.Y. and DUBLIN – 01 Oct 2012: IBM today announced that it has teamed with ESB ecars to implement a fully integrated smarter charging IT system that will help manage electric vehicle public charge points, which are being rolled out across Ireland by ESB ecars. Together the companies will add a layer of intelligence and convenience to the charging process, allowing EV drivers to access, charge and pay, using an identification card. Additionally, this project will provide utilities with access to energy usage data that can help improve smart grid operations, reduce power strain during peak charging times, and ensure reliable energy distribution to customers.
With approximately 1,000 public charging-points currently available, ESB Networks is on track to deliver one of the largest integrated and operational electric vehicle infrastructures in Europe. ESB Networks will use IBM’s Intelligent Electric Vehicle Enablement Platform to provide the services needed to operate and manage the charge-points installed throughout Ireland. (more…)
COLUMBUS, Ohio – Scientists have found that eliminating an enzyme from mice with symptoms of Alzheimer’s disease leads to a 90 percent reduction in the compounds responsible for formation of the plaques linked to Alzheimer’s disease.
That is the most dramatic reduction in this compound reported to date in published research.
The compounds are amyloid beta, or A-beta peptides; peptides are proteins, but are shorter in length. When A-beta peptides accumulate in excessive amounts in the brain, they can form plaques, which are a hallmark of Alzheimer’s disease. (more…)
A technique for creating a new molecule that structurally and chemically replicates the active part of the widely used industrial catalyst molybdenite has been developed by researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). This technique holds promise for the creation of catalytic materials that can serve as effective low-cost alternatives to platinum for generating hydrogen gas from water that is acidic.
Christopher Chang and Jeffrey Long, chemists who hold joint appointments with Berkeley Lab and the University of California (UC) Berkeley, led a research team that synthesized a molecule to mimic the triangle-shaped molybdenum disulfide units along the edges of molybdenite crystals, which is where almost all of the catalytic activity takes place. Since the bulk of molybdenite crystalline material is relatively inert from a catalytic standpoint, molecular analogs of the catalytically active edge sites could be used to make new materials that are much more efficient and cost-effective catalysts.
