Canadian brainpower at AAAS in Washington

2011-02-18
(Press-News.org) Washington (February 17) — Three leading Canadian language and speech experts will take centre stage in discussions on the latest developments in speech research at this year's annual meeting of the American Association for the Advancement of Science in Washington, D.C. (February 17-21).

Ellen Bialystok of York University has been a driving force in revealing the unique window that bilingualism opens on brain function. Her research disproves earlier claims of cognitive deficits among bilingual children, discovering, instead, that bilingual children and adults have distinct advantages over unilingual people, especially when performing non-language tasks. Her findings suggest that bilingualism provides lifelong advantages.

Janet F. Werker, of the University of British Columbia, focuses on how we acquire language, specifically on the first steps in infancy that launch the process of language acquisition. She was the first to show that infants begin life sensitive to the sound properties of all the world's languages and that listening experience serves to narrow their sensitivities to those used in their native language only. Her recent work includes studies of the perceptual processes that aid infants in acquiring two native languages and growing up bilingual.

University of Toronto's Luc De Nil discovered that stuttering is part of a generalized motor disorder that affects more than just speech. His research includes innovative non-verbal experiments, such as having adults and children master new and unusual finger-tapping sequences. Such exercises allow him to determine the brain processes involved and the developmental progression of this puzzling disorder over time.

Bialystok and Werker will share their findings at the session entitled Crossing Borders in Language Science: What Bilinguals Tell Us About Mind and Brain on Friday, February 18, from 1:30 p.m. to 4:30 p.m., Room 146A, Washington Convention Center.

De Nil will take part in the session From Freud to fMRI: Untangling the Mystery of Stuttering on Sunday, February 20, from 10:00 a.m. to 11:30 a.m., Room 146A, Washington Convention Center.

Both sessions will also be the subject of special AAAS news briefings in advance of the presentations. Newsroom participants should check their schedules for locations and times.

ASTRO publishes palliative radiotherapy for bone metastases guideline

2011-02-18
The American Society for Radiation Oncology (ASTRO) Clinical Affairs and Quality Committee has developed a guideline for the use of radiation therapy in treating bone metastases. The guideline will be published in the International Journal of Radiation Oncology•Biology•Physics, an official journal of ASTRO. Bone metastases are caused when a malignant tumor spreads to the bone. They can lead to debilitating effects including pain, fractures and paralysis due to spinal cord compression. The care of these patients requires collaboration between several types of cancer treatment ...

Catching space weather in the act

Catching space weather in the act
2011-02-18
Close to the globe, Earth's magnetic field wraps around the planet like a gigantic spherical web, curving in to touch Earth at the poles. But this isn't true as you get further from the planet. As you move to the high altitudes where satellites fly, nothing about that field is so simple. Instead, the large region enclosed by Earth's magnetic field, known as the magnetosphere, looks like a long, sideways jellyfish with its round bulb facing the sun and a long tail extending away from the sun. In the center of that magnetic tail lies the plasma sheet. Here, strange things ...

NASA sees former Tropical Storm Carlos still a soaker in the Northern Territory

NASA sees former Tropical Storm Carlos still a soaker in the Northern Territory
2011-02-18
Now a remnant low pressure area, former Tropical Storm Carlos continues to move southwest inland over Australia's Northern Territory and dump heavy amounts of rainfall. NASA's Aqua satellite saw some of the high thunderstorms within Carlos over land and extending north into the Timor Sea. The Atmospheric Infrared Sounder (AIRS) instrument onboard NASA's Aqua satellite measures cloud-top, sea surface and land temperatures. Those are important factors in determining the strength and power of a tropical cyclone. Sea surface temperatures need to be at least as warm 26.6 ...

NASA infrared satellite data see an intensifying Tropical Storm Dianne

NASA infrared satellite data see an intensifying Tropical Storm Dianne
2011-02-18
Infrared satellite data from NASA's Aqua satellite reveal that Tropical Storm Dianne is getting organized off the coast of Western Australia today. NASA's Atmospheric Infrared Sounder (AIRS) infrared imagery suggests that Dianne's center of circulation is consolidating and getting organized. There are bands of thunderstorms wrapping into the center of the storm, indicating strengthening is occurring. The AIRS instrument flies aboard NASA's Aqua satellite. The AIRS infrared image of Tropical Storm Dianne from Feb. 17 at 06:05 UTC (1:05 a.m. EST) showed a large area of ...

To increase physical activity, focus on how, not why

To increase physical activity, focus on how, not why
2011-02-18
COLUMBIA, Mo. – Most people know that exercise is important to maintain and improve health; however, sedentary lifestyles and obesity rates are at all-time highs and have become major national issues. In a new study, University of Missouri researchers found that healthy adults who received interventions focused on behavior-changing strategies significantly increased their physical activity levels. Conversely, interventions based on cognitive approaches, which try to change knowledge and attitudes, did not improve physical activity. "The focus needs to shift from increasing ...

NASA sees heavy rains in Tropical Storm Bingiza, possibly headed for second landfall

NASA sees heavy rains in Tropical Storm Bingiza, possibly headed for second landfall
2011-02-18
NASA satellite data indicates that Bingiza is still maintaining tropical storm intensity and carrying heavy rainfall over the Mozambique Channel as it prepares for its second landfall in Madagascar. Deadly Tropical Cyclone Bingiza, which crossed over northern Madagascar three days ago, has continued to affect Madagascar while moving along Madagascar's west coast. Bingiza had weakened from a powerful category 3 tropical cyclone with sustained winds of 100 kts (~115 mph/185 kmh) to tropical storm force winds of about 35 kts (~40 mph/65 kmh) when the Tropical Rainfall Measuring ...

Rewrite the textbooks

2011-02-18
Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body (input), and axons carry signals away (output). In one of many surprise findings, Northwestern University scientists have discovered that axons can operate in reverse: they can send signals to the cell body, too. It also turns out axons can talk to each other. Before sending signals in reverse, axons can perform their own neural computations without any involvement from the cell body or dendrites. This is contrary to typical neuronal communication ...

Psychological effects of BP oil spill go beyond residents of impacted shorelines

2011-02-18
GAINESVILLE, Fla. -- The psychological effects of the BP oil spill, the largest recorded environmental disaster in human history, extend far beyond people living around the areas of the Gulf of Mexico that were directly impacted by the spill, a new study finds. Writing in the online edition of the journal Environmental Health Perspectives, a publication of the National Institutes of Health, the researchers reported that even in areas that did not have oil exposure, people still experienced elevated levels of anxiety and depression and reduced ability to show resilience ...

Further research needed to develop evidence-based nutrition guidelines for cancer survivors

2011-02-18
St. Louis, MO, February 18, 2011 – Cancer survivors die of non-cancer-related causes at much higher rates than the general public. In 2008, the U.S. economic burden of cancer totaled over $228 billion but only 41% of these costs involved direct cancer care. The majority of expenses were attributed to increased morbidity, lost productivity, and premature mortality. A commentary published in the March 2011 issue of the Journal of the American Dietetic Association examines the current evidence supporting nutrition recommendations for preventing cancer recurrence and managing ...

Competing risks analysis highlights new targets in preventing ESRD and death of diabetics

2011-02-18
Patients with both type 1 diabetes and CKD have an increased risk of adverse outcomes. Despite aggressive treatment, many patients with type 1 diabetes and overt nephropathy develop End-Stage Renal Disease (ESRD) and/or succumb to a premature death. The competing risks of death and ESRD may confound the estimates of risk for each outcome. Now, the researchers at the University of Helsinki, University Hospital of Helsinki and Folkhälsan Research Center, Finland, and at the Queen Elisabeth Hospital and Baker IDI Heart and Diabetes Institute, Australia, have determined ...
