A University of Connecticut researcher and his team have discovered that a species of tiny aquatic organism prominent in harmful algal blooms sometimes called "red tide" is even deadlier than first thought, with potential consequences for entire marine food chains. Professor Hans Dam and his research group in the school's Department of Marine Sciences have discovered that the plankton species Alexandrium tamarense contains not one but two different types of toxins, one that's deadly to large organisms and one that's deadly to small predators. "If it's killing multicellular ...

Toronto, Canada – Neuroscientists have found strong evidence that vivid memory and directly experiencing the real moment can trigger similar brain activation patterns. The study, led by Baycrest's Rotman Research Institute (RRI), in collaboration with the University of Texas at Dallas, is one of the most ambitious and complex yet for elucidating the brain's ability to evoke a memory by reactivating the parts of the brain that were engaged during the original perceptual experience. Researchers found that vivid memory and real perceptual experience share "striking" similarities ...

PROVIDENCE, R.I. [Brown University] — A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators. That insight, published online this week in Proceedings of the National Academy of Sciences, prompts the question whether mice and other mammals have specially hardwired neural circuitry to trigger instinctive behavior in response to certain smells. In the series of experiments and observations described in the paper, the authors found that nerve cells ...

Premature babies are more likely to survive when they are born in high-level neonatal intensive care units (NICUs) than in hospitals without such facilities, and this benefit is considerably larger than previously reported. The likelihood that an extremely premature baby will survive if born in a high-technology, high-volume hospital unit was already known, but the current study, the largest to date, revealed a stronger effect. Pediatric researchers who analyzed more than 1.3 million premature births over a 10-year span found that the survival benefits applied not only ...

(Boston) - Researchers from Boston University School of Medicine (BUSM) in partnership with Indian researchers and HIV positive networks groups, have found that in India, non-disclosure of HIV serostatus to sex partners among both HIV-infected female sex workers (FSWs) and HIV-infected clients of FSWs is exceedingly common. These findings currently appear online in the journal AIDS and Behavior. No previous studies in India specifically, and few internationally, have assessed FSWs' and male clients' disclosure of HIV status to sex partners. Disclosure of HIV serostatus ...

A paleontological team that includes scientists from the American Museum of Natural History; University of California, Santa Barbara; and Case Western Reserve University has described two ancient species of South American rodents, including the oldest chinchilla, a discovery that substantiates what might be the earliest grasslands in the world. The two new species lived near a chain of volcanoes about 32.5 million years ago in what are now the steep slopes of a river valley in the Chilean Andes. Studies of the teeth of the ancient chinchilla support evidence from other ...

WASHINGTON (July 23, 2012) – A new study conducted by GW School of Medicine and Health Sciences (SMHS) researchers Edward C. De Fabo, Ph.D., Frances P. Noonan, Ph.D., and Anastas Popratiloff, M.D., Ph.D., has been published in the journal Nature Communications. Their paper, entitled "Melanoma induction by ultraviolet A but not ultraviolet B radiation requires melanin pigment," was published in June 2012. "This is the first time that UV-induced melanin formation (tanning), traditionally thought to protect against skin cancer, is shown to be directly involved in melanoma ...

CLEMSON, S.C. — Clemson University plant breeders announced a new high-yielding variety of oats. Named Graham, the new variety grows to medium height, withstands falling over (lodging), matures earlier and produces more seed than comparable varieties. "Graham has excellent seed yield potential, exceeding the Rodgers variety by 20 bushels per acre at some locations and produces a 32.2-pound bushel compared to 31.9-pound bushel for Rodgers," said Chris Ray, director of the S.C. Crop Improvement Association, which grows certified seed for sale to the public. The new ...

Thanks to tiny microneedles, eye doctors may soon have a better way to treat diseases such as macular degeneration that affect tissues in the back of the eye. That could be important as the population ages and develops more eye-related illnesses – and as pharmaceutical companies develop new drugs that otherwise could only be administered by injecting into the eye with a hypodermic needle. For the first time, researchers from the Georgia Institute of Technology and Emory University have demonstrated that microneedles less than a millimeter in length can deliver drug molecules ...

DURHAM, N.C. – A compound that mops up debris of damaged cells from the bloodstream may be the first in a new class of drugs designed to address one of medicine's most difficult challenges -- stopping the formation of blood clots without triggering equally threatening bleeding. In a mouse study published online July 23, 2012, in the journal Proceedings of the National Academy of Sciences, Duke University Medical Center scientists report that the experimental compound called PAMAM G-3 actually prevents activation of the process that leads to the formation of dangerous blood ...

CHAPEL HILL, NC – The use of the synthetic stimulants collectively known as "bath salts" have gained popularity among recreational drug users over the last five years, largely because they were readily available and unrestricted via the Internet and at convenience stores, and were virtually unregulated. Recent studies point to compulsive drug taking among bath salts users, and several deaths have been blamed on the bath salt mephedrone (4-methylmethcathinone or "meow-meow"). This has led several countries to ban the production, possession, and sale of mephedrone and ...

The FDA says baby bottles and sippy cups can no longer contain Bisphenol-A (BPA), an endocrine disruptor that mimics estrogen. But what about the hundreds of other plastic items, from water bottles to dental sealants, containing BPA? The FDA didn't go far enough, said Mercyhurst University Public Health Department Chair Dr. David Dausey. Dausey addresses the FDA's recent BPA ban in his latest vlog, The Dausey File: Public Health News Today. BPA has been associated with a wide range of health problems from metabolic disease to reproductive health defects. Dausey said ...

The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period. New research from the Niels Bohr Institute at the University of Copenhagen indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time. The results have been published in the scientific journal, Climate of the Past. In the warmer climate the atmospheric content of CO2 is naturally higher. The gas CO2 (carbon dioxide) is a green-house gas that ...

DURHAM, N.C. -- Stroboscopic training, performing a physical activity while using eyewear that simulates a strobe-like experience, has been found to increase visual short-term memory retention, and the effects last for 24 hours. Participants in a Duke University study engaged in physical activities, such as playing catch, while using either specialized eyewear that limits vision to only brief snapshots or while using eyewear with clear lenses that provides uninterrupted vision. Participants from the Duke community, including varsity athletes, completed a computer-based ...

WALLOPS ISLAND, Va. -- A large inflatable heat shield developed by NASA's Space Technology Program has successfully survived a trip through Earth's atmosphere while travelling at hypersonic speeds up to 7,600 mph. The Inflatable Reentry Vehicle Experiment (IRVE-3) was launched by sounding rocket at 7:01 a.m. Monday from NASA's Wallops Flight Facility on Wallops Island, Va. The purpose of the IRVE-3 test was to show that a space capsule can use an inflatable outer shell to slow and protect itself as it enters an atmosphere at hypersonic speed during planetary entry and ...

FRESNO, Calif. (July 23, 2012) – New research published in the Journal of the International Society of Sports Nutrition suggests that eating raisins may provide the same workout boost as sports chews. Conducted by researchers at the University of California-Davis, the study evaluated the effects that natural versus commercial carbohydrate supplements have on endurance running performance. Runners depleted their glycogen stores in an 80-minute 75% V02 max run followed by a 5k time trial. Runners completed three randomized trials (raisins, chews and water only) separated ...

Too often our memory starts acting like a particularly porous sieve: all the important fragments that should be caught and preserved somehow just disappear. So armed with pencils and bolstered by caffeine, legions of adults, especially older adults, tackle crossword puzzles, acrostics, Sudoku and a host of other activities designed to strengthen their flagging memory muscles. But maybe all they really need to do to cement new learning is to sit and close their eyes for a few minutes. In an article to be published in the journal Psychological Science, a publication of ...

Why do Native Americans experience high rates of diabetes? A common theory is that they possess fat-hoarding "thrifty genes" left over from their ancestors – genes that were required for survival during ancient cycles of feast and famine, but that now contribute to the disease in a modern world of more fatty and sugary diets. A newly published analysis of fossilized feces from the American Southwest, however, suggests this "thrifty gene" may not have developed because of how often ancient Natives ate. Instead, researchers said, the connection may have come from precisely ...
