Engineers Discover Why Toucan Beaks Are Models Of Lightweight Strength
In a paper to be published Dec. 1 in Acta Materialia, researchers report that the secret to the toucan beak's lightweight strength is an unusual bio-composite. The interior of the beak is rigid "foam"made of bony fibers and drum-like membranes sandwiched between layers of keratin, the protein that makes up fingernails, hair, and horn. 'Death Star'Black Hole Fires At Neighboring Galaxy
A jet from a black hole at the center of a galaxy strikes the edge of another galaxy. This is the first time such an interaction has been found. The jet impacts the companion galaxy at its edge and is then disrupted and deflected, much like how a stream of water from a hose will splay out after hitting a wall at an angle. Each wavelength shows a different aspect of this system, known as 3C321. The Chandra X-ray image provides evidence that each galaxy contains a rapidly growing supermassive black hole at its center. New Strategy For AIDS Vaccination: HIV Exploits Competition Among T-ce
New HIV research shows how competition among the human immune system's T cells allows the virus to escape destruction and eventually develop into full-blown AIDS. The study, slated to appear in Physical Review Letters, employs a computer model of simultaneous virus and immune system evolution. It also suggests a new strategy for vaccinating against the virus -- a strategy that the computer simulations suggest may prevent the final onset of AIDS. NYU Dental Researcher Finds Link Between Pregnancy And Tooth Loss
The old wives tale, "for every child the mother loses a tooth,"has some validity, according to New York University College of Dentistry's Dr. Stefanie Russell. Los Pobladores 200: Descendents of the Founders El Pueblo de Los Angel
Website of this group "the primary goal [of which] was to locate and organize present day descendants of the original founding families of Los Angeles."Features details about group activities (such as the annual history walk on September 4, the date of the founding of Los Angeles), and an archive with names and brief histories of founding families and the soldiers who escorted them to El Pueblo de La Reina de Los Angeles. Skimmed Milk Reduces The Risk Of Hypertension By 50 Percent
The American Journal of Clinical Nutritionis the peer-reviewed journal of international reference in the field of nutrition. In the November issue, it published an article which demonstrated that non-fat milk products can reduce the risk of hypertension by 50 percent, while nevertheless there is no appreciable connection between that disease and the consumption of whole milk. Thinking Makes It So: Science Extends Reach Of Prosthetic Arms
A technique allowing a prosthetic arm to respond directly to brain signals has the potential to provide more arm and hand movements, beyond the four the technique has already achieved, a new study shows. The researchers have begun work with two US Army medical centers to help soldiers who have lost limbs. Violent Boys In Unsafe Conditions Less Prone To Depression
Violent adolescent boys in neighborhoods where they routinely witness violence tend to be less depressed than other violent youths, says a new study by Raymond Swisher of Cornell University and former student Robert D. Latzman. The study is published in the Journal of Community Psychology (33: 355-371, May 2005). Chimpanzees Discovered Making And Using Spears To Hunt Other Primates
Chimpanzees in Senegal are regularly making and using spears to hunt other primates -- without human assistance -- according to research led by an Iowa State University anthropologist. That study, funded by the National Geographic Society, is the first to report habitual tool use by non-humans while hunting other vertebrates. Rensselaer Researcher To Showcase New Solar Underwater Robot Technolog
A new solar-powered underwater robot technology developed for undersea observation and water monitoring will be showcased at a Sept. 16 workshop on leading-edge robotics to be held at the National Science Foundation (NSF) in Arlington, Va.
