  • Online e-cigarette vendors engage customers using popular internet tools
    First introduced in the United States in 2007, electronic cigarettes have risen dramatically in part because they are popularly considered safer and more socially acceptable than combustible cigarettes and because there are fewer restrictions on their purchase and use. A study now points to aggressive online marketing tactics that make purchasing e-cigarettes easy for all ages.

  • Researcher calls for changes to colorectal cancer screening guidelines
    Colorectal cancer will claim the lives of close to 50,000 Americans this year, according to the American Cancer Society. Screening is the most effective way to reduce the risk of dying from the disease, yet as a physician argues in a recent editorial, current recommendations to screen older people with a family history of colorectal cancer, specifically with colonoscopy every five years, is not justified for most patients.

  • Signs of ancient mega-tsunami could portend modern hazard
    Scientists working off west Africa in the Cape Verde Islands have found evidence that the sudden collapse of a volcano there tens of thousands of years ago generated an ocean tsunami that dwarfed anything ever seen by humans. The researchers say an 800-foot wave engulfed an island more than 30 miles away. The study could revive a simmering controversy over whether sudden giant collapses present a realistic hazard today around volcanic islands, or even along more distant continental coasts.
  • To breathe or to eat: Blue whales forage efficiently to maintain massive body size
    As the largest animals to have ever lived on Earth, blue whales maintain their enormous body size through efficient foraging strategies that optimize the energy they gain from the krill they eat, while also conserving oxygen when diving and holding their breath, a new study has found.

    Imitation behaviors play a key role in many collective phenomena seen in animals. An analysis of the collective movements of grazing sheep has revealed that sheep alternate slow dispersion phases with very fast regrouping, in which they imitate the behavior of their neighbors. This study shows that the intensity with which the sheep mimic one another plays a crucial role in the ability of a herd to maximize the grazing area explored while minimizing the time needed to regroup when faced with potential dangers.

  • Researchers identify cause of inherited form of extreme nearsightedness
    'Why, Grandma, what big eyes you have!' Though similar in appearance, the hidden cause of those big eyes Little Red Riding Hood notices in Grimms' fairy tale has nothing to do with the hidden cause of enlarged eyeballs in buphthalmia, a genetic mechanism causing this devastating eye disease which has now been uncovered by researchers. Patients afflicted are severely myopic, or nearsighted.

  • Signals from empty space
    What are the properties of the vacuum, the absolute nothingness? So far, physicists have assumed that it is impossible to directly access the characteristics of the ground state of empty space. Now, a team of physicists has succeeded in doing just that. They demonstrated a first direct observation of the so-called vacuum fluctuations by using short light pulses while employing highly precise optical measurement techniques.

    Research finds around 1000 molecular reactions to exercise, opening the door for drug treatments to mirror the health benefits of exercise.
  • Tallness linked to increased risk of premature death for patients on dialysis
    Tallness has been associated with higher premature mortality risk and shorter life spans in patients on dialysis. The association was observed in white, Asian, and American Indian/Alaskan native patients, but not in black patients. The overall paradoxical relationship between height and premature death was not explained by concurrent illness, socioeconomic status, or differences in care.

    A new study has identified a number of genes that are repressed at various time points after memory formation, providing important clues as to how long-term memories are formed.
  • Genetic mutations linked to a form of blindness
    Scientists have identified two naturally occurring genetic mutations in dogs that result in achromatopsia, a form of blindness. One of the most promising avenues for developing a cure, however, is through gene therapy, and to create those therapies requires animal models of disease that closely replicate the human condition.
  • Fatty liver disease and scarring have strong genetic component
    Hepatic fibrosis, which involves scarring of the liver that can result in dysfunction and, in severe cases, cirrhosis and cancer, may be as much a consequence of genetics as environmental factors.
  • Research shows a cause of gastrointestinal symptoms in Type 1 diabetes
    A molecular basis has been found for why 80 percent of patients with longstanding Type 1 diabetes have chronic gastrointestinal symptoms including gastroparesis (delayed emptying of food), irritable bowel syndrome, abdominal distension and fecal incontinence, significantly reducing their quality of life.
  • New polymer creates safer fuels
    Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact. Researchers have discovered a polymeric fuel additive that can reduce the intensity of postimpact explosions that occur during accidents and terrorist acts. Furthermore, preliminary results show that the additive can provide this benefit without adversely affecting fuel performance.
  • Study finds gaps in clinical genetic counseling services for women undergoing BRCA testing
    Medical researchers have published results from a national study identifying factors and outcomes associated with the use of genetic counseling and testing services for hereditary breast and ovarian cancer in the community setting.

  • Hotel 'greenwashing' dirties eco-friendly reputation
    Hotels across the globe are increasingly encouraging guests to embrace green practices. Yet while guests think they are supporting the environment by shutting off lights and reusing towels, they may in fact be victims of 'greenwashing,' a corporation's deceitful practice of promoting environmentally friendly programs while hiding ulterior motives.
