Nuclear weapons: Predicting the unthinkable
If a nuclear weapon were detonated in a metropolitan area, how large would the affected area be? Where should first responders first go? According to physicist Fernando Grinstein, we have some initial understanding to address these questions, but fundamental issues remain unresolved.   view more (2009-11-23)

Aquatic creatures mix ocean water
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.   view more (2009-11-23)

Measuring and modeling blood flow in malaria
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells.   view more (2009-11-23)

New brain findings on dyslexic children
The vast majority of school-aged children can focus on the voice of a teacher amid the cacophony of the typical classroom thanks to a brain that automatically focuses on relevant, predictable and repeating auditory information, according to new research from Northwestern University.   view more (2009-11-12)

Neural mechanism reveals why dyslexic brain has trouble distinguishing speech from noise
New research reveals that children with developmental dyslexia have a deficit in a brain mechanism involved in the perception of speech in a noisy environment.   view more (2009-11-12)

Population movement can be critical factor in dengue's spread
Human movement is a key factor of dengue virus inflow in Rio de Janeiro, according to results from researchers based at the Oswaldo Cruz Foundation (Fiocruz) in Brazil.   view more (2009-11-10)

Excitation pattern peak is more important determinant of vowel quality
The perceptions of five Chinese vowel /u, o, a, y, i/ and many perceptional phenomena can be explained well by the excitation pattern peaks. The study is reported in Science in China, Series F-Information Sciences, Volume 52,Issues 10 (Oct, 2009).   view more (2009-11-06)

LANL Roadrunner simulates nanoscale material failure
Very tiny wires, called nanowires, made from such metals as silver and gold, may play a crucial role as electrical or mechanical switches in the development of future-generation ultrasmall nanodevices.   view more (2009-10-30)

General anesthetics lead to learning disabilities in animal models
Studies by researchers at Wake Forest University School of Medicine have shown that blocking the NMDA receptor in immature rats leads to profound, rapid brain injury and disruption of auditory function as the animals mature.   view more (2009-10-23)

Women outperform men when identifying emotion

tudy: The new buzz on detecting tinnitus
It's a ringing, a buzzing, a hissing or a clicking - and the patient is the only one who can hear it. Complicating matters, physicians can rarely pinpoint the source of tinnitus, a chronic ringing of the head or ears that can be as quiet as a whisper or as loud as a jackhammer.    view more (2009-10-05)

MU Researchers Use Computational Models to Study Fear
The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear.   view more (2009-10-01)

Taking up music so you can hear
Anyone with an MP3 device -- just about every man, woman and child on the planet today, it seems -- has a notion of the majesty of music, of the primal place it holds in the human imagination.   view more (2009-08-18)

Improving impaired attention may help patients recover from stroke

The Value of Variation: Ecologists Consider the Causes and Consequences
Consider the case of the three-spine stickleback. These tiny fish that thrive in oceans and in fresh water might appear to be the same, yet ecologists are finding that they are actually a diverse collection of very specialized individuals.   view more (2009-07-23)

Memory test and PET scans detect early signs of Alzheimer's
A large study of patients with mild cognitive impairment revealed that results from cognitive tests and brain scans can work as an early warning system for the subsequent development of Alzheimer's disease.   view more (2009-07-14)

Scientists from Scotland to Sweden Arrive at NIMBioS to Study Bovine TB
In 2008, the U.S. Department of Agriculture spent $31 million to depopulate herds of cattle affected by bovine tuberculosis (TB), even though the risk of the disease has been significantly reduced in the U.S. over the past several decades.   view more (2009-07-13)

Laboring without the labor bed: It's a good thing
A University of Toronto pilot study that re-conceptualized the hospital labour room by removing the standard, clinical bed and adding relaxation-promoting equipment had a 28 per cent drop in infusions of artificial oxytocin, a powerful drug used to advance slow labours.   view more (2009-07-07)

Australia's climate: Drought and flooding in annual rings of tropical trees
Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation.   view more (2009-06-12)
