New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. That's the topic of a report by an international expert on solar energy scheduled for the November 2 issue of ACS' Inorganic Chemistry, a bi-weekly journal. It describes a long-awaited, inexpensive method for solar energy storage that could help power homes and plug-in cars in the future while helping keep the environment clean.
GAINESVILLE, FL—Carotenoids, the family of yellow to red pigments responsible for the striking orange hues of pumpkins and the familiar red color of vine-ripe tomatoes, play an important role in human health by acting as sources of provitamin A or as protective antioxidants. Pumpkins and squash, available in a wide range of white, yellow, and orange colors, are excellent sources of dietary carotenoids, particularly lutein, alpha-carotene, and beta-carotene.
Unrelenting toothache means a visit to the dentist is inevitable, and if the tooth decay is really bad root canal treatment is often the only option. The dentist first removes the nerve completely and then closes the ensuing canal with a filler. This must be airtight to prevent bacteria from entering and causing renewed inflammation. On the other hand, the material must also be removable. If the natural crown is severely damaged, the dentist will anchor a root post in the previously filled canal using dental cement.
MADISON, WI, NOVEMBER 4, 2009 -- The world's greatest wines are the result of a threefold synergy among grape variety, human input, and something called the "terroir" -- a term often defined as the vineyard site, soil, and climate.
STILLWATER, OK—African violets have a mixed reputation. Their delicate, colorful flowers and furry, soft leaves make them a favorite among home gardeners and growers. But the striking plants are often regarded as temperamental: a precise recipe of light, moisture, warm temperatures, high humidity, and fertilizer is required to encourage african violets to grow and flower.
TIFTON, GA—Pecan trees, like many fruit trees, have a tendency to bear fruit in cycles, producing a large crop in one or two years, followed by one or two years with little or no crop. This cycle, called "alternate bearing", is the most profit-limiting biological problem facing pecan producers; the inconsistent production pattern creates supply and marketing challenges that can have severe negative effects on the pecan industry.
WEST LAFAYETTE, Ind. - Chief executives in 35 of the top Fortune 500 companies were overpaid by about 129 times their "ideal salaries" in 2008, according to a new type of theoretical analysis proposed by a Purdue University researcher to determine fair CEO compensation.
In addition to building muscle, weightlifting is also a prescription for self-esteem among breast cancer survivors, according to new University of Pennsylvania School of Medicine research. Breast cancer survivors who lift weights regularly feel better about bodies and their appearance and are more satisfied with their intimate relationships compared with survivors who do not lift weights, according to a new study published in the journal Breast Cancer Research and Treatment.
The details of your personal life, such as grocery purchases and pizza topping preferences, are collected every day ― online and by club and discount cards from the gym, department store and supermarket. Though this data seems innocent enough, when it's put together it can tell a whole lot about your health, finances and behavior. That information, a Tel Aviv University researcher reminds us, could eventually be used against you.
ROCHESTER, Minn. -- Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings.
"The use of MRI is particularly significant in the diagnosis of patients with myocarditis because it is a standard, noninvasive method," says Leslie Cooper Jr., M.D., Mayo Clinic Division of Cardiovascular Diseases.
(Washington, DC • Nov. 3, 2009) – Launched from Vandenberg Air Force Base, Calif., aboard an United Launch Alliance Atlas V launch vehicle, Oct. 18, 2009, the Special Sensor Ultraviolet Limb Imager (SSULI) developed by NRL's Space Science Division and Spacecraft Engineering Department offers a first of its kind technique for remote sensing of the ionosphere and thermosphere from space.
COLUMBIA, Mo. - Frogs are croaking in clear-cut forests, but not exactly in their traditional manner. University of Missouri researchers found that removing all of the trees from a section of the forest had a negative effect on amphibians during their later life cycles, but had some positive effects during amphibians' aquatic larva stages at the beginning of their lives. To lessen the negative effects during the later life stage, Semlitsch recommends partial or selection cuts to forests rather than completely removing trees from an area.
Marking a significant bench to bedside research milestone in Singapore, the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, and the National University Hospital (NUH) launched the IBN iCare and the NUH Eye Centre @ Biopolis at an official opening ceremony officiated by the Senior Minister of State for Trade and Industry and Education, S. Iswaran, at the Biopolis on Nov. 3, 2009.
COLUMBIA, Mo. – When searching for basketball videos online, a long list of websites appears, which may contain a picture or a word describing a basketball. But what if the computer could search inside videos for a basketball? Researchers at the University of Missouri are developing software that would enable computers to search inside videos, detect humans and specific objects, and perform other video analysis tasks.
CHICAGO (November 3, 2009)––Standard adjuvant treatment for HER2-positive breast cancer patients, following primary surgery for their cancer, is Trastuzumab (Herceptin)––typically used in combination with chemotherapy. However, a new study by researchers at Fox Chase Cancer Center reports that it may be safe to treat these patients with both Trastuzumab and adjuvant radiation therapy. The study will be presented today at the annual meeting of the American Society for Radiation Oncology (ASTRO).
