As Earth's climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations. While scientists have documented such shifts for many plants and animals, the ranges of others seem stable. When species respond in different ways to the same amount of warming, it becomes more difficult for ecologists to predict future biological effects of climate change--and to plan for these effects. In a study published this week in the journal Nature, University of Wyoming ecologist Daniel Doak and Duke University ecologist William ...

Researchers at the Institute for Research in Immunology and Cancer (IRIC) of the Université de Montréal have identified a new mechanism controlling the transmission of an abnormal signal at the origin of several cancers. In an article published in the journal Cell, Marc Therrien's team explains the recent discovery of a protein complex that controls the RAS/MAPK signalling pathway, responsible for some of the deadliest cancers, including pancreatic, colon and lung cancers, and melanomas. This regulating mechanism could prove to be a promising therapeutic target for the ...

Three NASA satellites are keeping tabs on Typhoon Megi and noticed that it was strengthening in the South China Sea today, but increasing wind shear may again weaken the system over the next couple of days. NASA's TRMM, CloudSat and Aqua satellite captured images of Megi's clouds, rainfall and eye as they passed over the storm and saw clouds higher than 9 miles filled with ice, creating heavy rainfall. The Tropical Rainfall Measuring Mission (TRMM) satellite passed over Typhoon Megi from its vantage point in space on October 18 at 2321 UTC (7:31 p.m. EDT) and saw that ...

The GOES-13 satellite keeps a continuous eye over the eastern U.S., the Caribbean Sea, Gulf of Mexico and Atlantic Ocean, and noticed that System 99L is much better organized today, October 20, hinting that it could become a tropical depression later today. At 8 a.m. EDT on Wednesday, October 20, System 99L, a low pressure system about 150 miles southwest of Grand Cayman appears to be getting organized as it drifts eastward in the Caribbean Sea. System 99L is showing more organization than it did yesterday, despite strong upper-level winds that are currently inhibiting ...

Princeton computer scientists have developed a new way of tracing the origins and spread of ideas, a technique that could make it easier to gauge the influence of notable scholarly papers, buzz-generating news stories and other information sources. The method relies on computer algorithms to analyze how language morphs over time within a group of documents -- whether they are research papers on quantum physics or blog posts about politics -- and to determine which documents were the most influential. "The point is being able to manage the explosion of information made ...

Magicians rely on misdirection—drawing attention to one place while they're carrying out their tricky business somewhere else. It seems like people with autism should be less susceptible to such social manipulation. But a new study in the U.K. finds that people with autism spectrum disorder are actually more likely to be taken in by the vanishing ball trick, where a magician pretends to throw a ball in the air but actually hides it in his hand. In the vanishing-ball illusion, a magician throws a ball in the air a few times. On the last throw, he merely pretends to throw ...

Conventional wisdom has long been negative on Africa. Historically, it has been seen as a failing continent, plagued by deep-rooted problems — poverty, corruption, war, and disease. But after four decades of relative stagnation, Africa has been growing rapidly. Since the 1990s, many African countries have seen economic and political improvements, more transparent elections, increased democracy and freedom of press. But these successes are not well understood. In 2007, the National Bureau of Economic Research (NBER), the leading nonprofit economics research organization ...

WASHINGTON, Oct. 20 -- Scientists and engineers from around the world will gather on the shores of Lake Ontario in Rochester, N.Y. next week to discuss some of the latest breakthroughs in lasers and optics and their applications to cutting-edge science, the development of new materials, and medicine.

CORVALLIS, Ore. – Severe burn injuries in children have been shown to rapidly deplete the levels of vitamin E in their body's adipose, or fat tissues, a new clinical study has found. Stored levels of this important antioxidant were reduced more in a few weeks than might normally be possible in years. An analysis of eight children with third-degree burns over much of their body found they lost almost half of their stored vitamin E in three weeks, even though they were being given about 150 percent of the recommended daily allowance of vitamin E and other nutrients in ...

Researchers at the Hawai'i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai'i at Mānoa's School of Ocean and Earth Science and Technology have made a remarkable new discovery. When most people envision coral, they typically think of shallow-water reef-building corals found along beaches and tropical nearshore habitats. These "typical" corals are dependent upon photosynthetic algae (also known as Symbiodinium or zooxanthellae) found in their tissues to obtain nutrients to live off of. In deeper less known waters, closely related ...

(SACRAMENTO, Calif.) — A study of the options for reducing cancer incidence and mortality among women who have been treated for precancerous cervical lesions found that an annual conventional Pap smear is a cost effective strategy. Joy Melnikow, professor in the Department of Family and Community Medicine and colleagues tested several follow-up screening strategies for the 500,000 American women diagnosed and treated for cervical intraepithelial neoplasia (CIN), abnormal cervical cell growth that can lead to cervical cancer. The first comprehensive study of its kind, ...

A University of Washington Medical Center patient on Thursday, Oct. 21, will be the world's first recipient of a device that aims to quell the disabling vertigo associated with Meniere's disease. The UW Medicine clinicians who developed the implantable device hope that success in a 10-person surgical trial of Meniere's patients will lead to exploration of its usefulness against other common balance disorders that torment millions of people worldwide. The device being tested – a cochlear implant and processor with re-engineered software and electrode arrays – represents ...

Providing computed tomography colonography (CTC) — otherwise known as virtual colonoscopy — as an alternative to conventional colonoscopy could improve colorectal cancer (CRC) screening rates, according to a study in the November issue of the American Journal of Roentgenology (www.ajronline.org). CRC is the second leading cause of cancer in the U.S. "While colonoscopy is currently the preferred test for CRC screening, the invasive and time-consuming characteristics of the test are often cited as reasons for noncompliance with screening," said Fouad J. Moawad, lead author ...

Computed tomography colonography (CTC) — otherwise known as virtual colonoscopy — is feasible in remote health centers where optimal colonoscopy is limited, according to a study in the November issue of the American Journal of Roentgenology (www.ajronline.org). The study was performed at Fort Defiance Indian Hospital in Fort Defiance, AZ, and Tuba City Regional Health Care Center in Tuba City, AZ, both of which are rural medical centers serving Native American, mainly Navajo, populations. After brief on-site instruction, including performing a CTC examination on a volunteer ...

RICHLAND, Wash. -- A new technique that searches blood for the tiniest remnants of broken down proteins has revealed new information about how cells crank up cancer activators called proteases. The results improve researchers' understanding of the mechanics of breast cancer and point to where to look for possible indicators of early disease. Appearing this week in PLoS ONE, the research shows previously unknown contributing factors to protease activation, which helps spread cancer: cancer cells almost completely chew up small protein pieces that normally put the brakes ...

Curcumin, the major component in the spice turmeric, when combined with the drug Cisplatin enhances the chemotherapy's suppression of head and neck cancer cell growth, researchers with UCLA's Jonsson Cancer Center have found. A naturally occurring spice widely used in South Asian and Middle Eastern cooking, Turmeric has long been known to have medicinal properties, attributed to its anti-inflammatory effects. Previous studies have shown it can suppress the growth of certain cancers, said Dr. Marilene Wang, a professor of head and neck surgery, lead author of the study ...

Mutually beneficial partnerships among species may play highly important but vastly underrecognized roles in keeping the Earth's ecosystems running, a group of evolutionary biologists suggests in a study. The authors present evidence that human impacts may be forcing these mutualist systems down unprecedented evolutionary paths. "With global climate change, evolutionary change can happen very rapidly, over a few years," said Judith Bronstein, a professor of ecology and evolutionary biology at the UA's College of Science and senior author on the paper. "That can be a ...
