Early snowmelt caused by climate change in the Colorado Rocky Mountains snowballs into two chains of events: a decrease in the number of flowers, which, in turn, decreases available nectar. The result is decline in a population of the Mormon Fritillary butterfly, Speyeria mormonia. Using long-term data on date of snowmelt, butterfly population sizes and flower numbers at the Rocky Mountain Biological Laboratory, Carol Boggs, a biologist at Stanford University, and colleagues uncovered multiple effects of early snowmelt on the growth rate of an insect population. "Predicting ...

In the wilds of New York City--or as wild as you can get that close to skyscrapers--scientists have found a new leopard frog species. For years, biologists mistook it for a more widespread variety of leopard frog. While biologists regularly discover new species in remote rainforests, finding this one in ponds and marshes--sometimes within view of the Statue of Liberty--is a big surprise, said scientists from the University of California, Los Angeles; Rutgers University; the University of California, Davis and the University of Alabama. "For a new species to go unrecognized ...

You've been feeling under the weather. You Google your symptoms. A half-hour later, you're convinced it's nothing serious—or afraid you have cancer. More than 60 percent of Americans get their health information online, and a majority of those decide whether to see a doctor based on what they find. "Wow, this is an era of self-diagnosis," thought Arizona State University psychologist Virginia Kwan, learning that statistic. How might information accessed online affect individual health decisions? In a new study, Kwan and her colleagues found that the way information is ...

TORONTO, ON—Scientists at the University of Toronto have found a molecular mechanism that plays a key role in the transition of Candida albicans yeast into disease-causing fungus—one of the leading causes of hospital-acquired infection. The finding highlights the importance of heat in fungal growth, and provides a new target for drug therapies to counter Candida albicans infection. Candida albicans is a normally harmless yeast that is present in all humans. It becomes infectious in various genetic and environmental conditions, with temperature as a key determinant. It ...

NEW YORK (March 16, 2012)—A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region's marine mammals and the local communities that rely on them for food security and cultural identity, according to an Alaska Native groups and the Wildlife Conservation Society who convened at a recent workshop. The workshop—which ran from March 12-14—examined the potential impacts to the region's wildlife and highlighted priorities for future management of shipping in the region. The meeting included participants ...

Glacial meltwater increases biodiversity in mountainous freshwater ecosystems. As glaciers vanish due to global warming, so will those species dependent upon the icy runoff. This is the conclusion of a study authored by researchers from, among other institutions, the University of Copenhagen. The article "Glacial river biodiversity" with the alarming new findings can be found in the journal Nature Climate Change. "The knowledge is new and startling. Glacial runoff is cold, nutrient-poor and physically unstable, and therefore, typically species-poor. Traditionally, we ...

Researchers from Clemson University have found a way to create temporary holes in the membranes of live cells using a standard inkjet printer. The method will be published in JoVE, the Journal of Visualized Experiments, on March 16. "We first had the idea for this method when we wanted to be able to visualize changes in the cytoskeleton arrangement due to applied forces on cells," said paper-author Dr. Delphine Dean. She said other researchers have been using this method to print cells onto slides, but that they have only recently discovered that printing the cells ...

The European Union's Habitats Directive is now 20 years old, and its network of protected areas, known as Natura 2000, is nearing completion. After a slow start, the network now includes some 26 000 protected sites and covers approximately 18% of the EU's land surface as well as significant areas of sea. It is widely considered to be the world's largest network of protected areas based on agreed site selection criteria. The review has been published in the newly launched open-access journal Nature Conservation. Douglas Evans, seconded to the Paris-based European Topic ...

PROVIDENCE, R.I. [Brown University] — Female mouse fetuses exposed to very high doses of a common industrial chemical that makes plastics more pliable develop significant reproductive alterations and precancerous lesions as they grow up, according to a new toxicology study conducted at Brown University. The administered doses of MEHP, the chemical that results when animals metabolize the industrial phthalate DEHP, were much higher than any normal environmental exposure that people or animals would encounter, said Mary Hixon, assistant professor of pathology and laboratory ...

BUFFALO, N.Y. -- Firms that make a previously patented innovation accessible to competitors increase overall likelihood of improving upon that breakthrough while also raising profits for the original innovator and market welfare, according to a study by a University at Buffalo economist. The practice of free-licensing -- giving up patent protection -- corresponds to an evolutionary step in the study of patents and their effect on innovation, says the study's author Gilad Sorek, assistant visiting professor of economics at UB. "This research arose from the notion that ...

TAMPA, Fla. (March 16, 2012) – An international team of researchers from the United States and Australia, including researchers at Moffitt Cancer Center in Tampa, Fla., have found that the oral BRAF inhibitor vemurafenib (PLX4032) when tested in a phase II clinical trial offered a high rate of response in patients with previously treated metastatic melanoma and who had the BRAF mutation. More than 50 percent of the patients in the trial had positive, prolonged responses and a median survival of almost 16 months. The study was published in a recent issue of the New England ...

UAB researchers developed a new vehicle to release proteins with therapeutic effects. The vehicles are known as "bacteria inclusion bodies", stable insoluble nanoparticles which are found normally in recombinant bacteria. Even though these inclusion bodies traditionally have been an obstacle in the industrial production of soluble enzymes and biodrugs, they were recently recognised to have large amounts of functional proteins with direct values in industrial and biomedical applications. The research team led by Antoni Villaverde from the Institute of Biotechnology and ...

The seas are creeping higher as the planet warms. But how high could they go? Projections for the year 2100 range from inches to several feet, or even more. The sub-tropical islands of Bermuda and the Bahamas are two seemingly unlikely places scientists have gone looking for answers. The cliffs and ancient reefs on Bermuda and the Bahamas have lured fossil-hunters for decades. The land on the Bahamas, for example, has a foundation of fossil coral; the stone is derived from the disintegration of age-old coral reefs and seashells. These areas are now attracting scientists ...

Despite the amazing advances in the field of medicine, many are still suffering from treatable and avoidable oral health conditions. The Center for Disease Control and Prevention's 2011 report on America's overall oral health shows that nearly a quarter of those over the age of 65 have lost all of their teeth due to trauma, gum disease, and tooth decay. This is why the leading Torrance dentist, Dr. Robert Mondavi, is now offering huge discounts to all dental implants this spring for those patients that would like to restore their smile permanently and painlessly. Dental ...

A fundamental shift in the Indian monsoon has occurred over the last few millennia, from a steady humid monsoon that favored lush vegetation to extended periods of drought, reports a new study led by researchers at the Woods Hole Oceanographic Institution (WHOI). The study has implications for our understanding of the monsoon's response to climate change. The Indian peninsula sustains over a billion people, yet it lies at the same latitude as the Sahara Desert. Without a monsoon, most of India would be dry and uninhabitable. The ability to predict the timing and amount ...

Who wouldn't pay a penny for a sports car? That's the mentality some popular online auctions take advantage of -- the opportunity to get an expensive item for very little money. In a study of hundreds of lowest unique bid auctions, Northwestern University researchers asked a different question: Who wins these auctions, the strategic gambler or the lucky one? The answer is the lucky. But, ironically, it's a lucky person using a winning strategy. The researchers found that all players intuitively use the right strategy, and that turns the auction into a game of pure ...

Le Bonheur Professor Russell Chesney, M.D. believes he knows what was ailing Tiny Tim, the iconic character from Charles Dickens' "A Christmas Carol." Based on detailed descriptions of both the symptoms and living conditions of 18th century London, Dr. Chesney hypothesizes that Tiny Tim suffered from a combination of rickets and tuberculosis (TB). His findings were published in the March 5 edition of Archives of Pediatrics and Adolescent Medicine. Dr. Chesney noted during the time the novel was written, 60 percent of children in London had rickets and nearly 50 percent ...

Eighty-eight percent of Americans now own a cell phone, forming a massive network that offers scientists a wealth of information and an infinite number of new applications. With the help of these phone users — and their devices' cameras, audio recorders, and other features — researchers envision endless possibilities for gathering huge amounts of data, from services that collect user data to monitor noise pollution and air quality to applications that build maps from people's cell phone snapshots. Today, user data provides some opportunities; for example, researchers ...

SAN DIEGO -- Obesity appears to significantly increase the risk of death tied to sleeping pills, nearly doubling the rate of mortality even among those prescribed 18 or fewer pills in a year, researchers reported Friday. "Obesity emerged as a marker of increased vulnerability," said Robert Langer, M.D., M.P.H., at the annual American Heart Association's Epidemiology and Prevention | Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions in San Diego. "The associations between sleeping pills and increased mortality were present, and relatively stronger, ...

Northern Australia's Pilbara coast is under warnings, alerts and watches as powerful Cyclone Lua nears for a landfall. NASA's Aqua satellite has been providing infrared, visible and microwave data on Lua that have shown forecasters the storm is strengthening on its approach to land. Two of the most recent infrared images of Cyclone Lua were captured from the Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite. The AIRS instrument captured infrared images of Cyclone Lua on March 15 at 1741 UTC and March 16 at 0553 UTC. The later image appeared ...
