Arizona State epidemiologist to explore dynamics of Mexico's H1N1 pandemic
Influenza surveillance mechanisms in Mexico were adequate during the fast-spreading H1N1 outbreak in 2009, yet Mexico did not have the infrastructure to quickly identify the emergence of this novel strain, according to Arizona State University epidemiologist Carlos Castillo-Chavez, director of ASU's Mathematical, Computational and Modeling Sciences Center.

Many cancer patients in Europe are being denied access to adequate pain relief because of over-zealous regulations restricting the availability and accessibility of opioid-based drugs such as morphine.

ASU researcher outlines strategies to curb urban heat island
Protect yourself from the summer sun is good advice to children who want to play outside on a hot summer day and it is good advice to cities as a way to mitigate the phenomenon known as urban heat island, said Harvey Bryan, an ASU professor of architecture.

Call made for better metrics for energy savings
A Michigan State University professor says if the world is to make better decisions when it comes to developing new energy sources, it needs to have better methods of measuring progress toward its energy goals.

Comparison shows robot-assisted option offers advantages for kidney surgery
A comparison of two types of minimally invasive surgery to repair kidney blockages that prevent urine from draining normally to the bladder found that robot-assisted surgery was faster and resulted in less blood loss and shorter hospital stays.

Word learning in deaf children with cochlear implants
Indiana University School of Medicine researcher reports at 2010 AAAS meeting that deaf children's word-learning skill was strongly affected by early auditory experience, whether that experience was through normal means or with a cochlear implant.

New insights into helping marine species cope with climate change
Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die.

Will coral reefs disappear?
NSERC-funded researcher Dr. Simon Donner, an assistant professor in the department of geography at the University of British Columbia, will be talking about the vulnerability of coral reefs to climate change due to higher ocean temperatures.

New round of UREP grants for WCMC-Q students
Twenty-eight WCMC-Q students have received grants totaling $280,000 in the latest, seventh, round of funding from the Undergraduate Research Experience Program to conduct advanced research projects with faculty members.

CU physicists use ultra-fast lasers to open doors to new technologies unheard of just years ago
For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging.

Tracing and screening of airline passengers for tuberculosis highly inefficient and unlikely to prevent the spread of disease
Contrary to current international guidelines, there is little risk of tuberculosis transmission linked to air travel, and tracing and screening air passengers and crew who might have been exposed to a person with tuberculosis is a highly inefficient resource-intensive process.

Quantum leap for phonon lasers
Physicists have taken major step forward in the development of practical phonon lasers, which emit sound in much the same way that optical lasers emit light.

Participation 'important for healthy marine parks'
The involvement of locals is a key ingredient in the success of marine parks which protect coral reefs and fish stocks.

From uncharted region of human genome, clues emerge about origins of coronary artery disease
Berkeley Lab scientists have learned how an interval of DNA in an unexplored region of the human genome increases the risk for coronary artery disease, the leading cause of death worldwide.

Cultural history colors thought about bioethics, evolution
Popularized ideas about evolution assume that some human groups are more evolved than other human groups.

LSU biologist and playwright hosts symposium on 'Science in the Theatre' at 2010 AAAS Conference
Vince LiCata, LSU's Louis S. Flowers Professor of Biological Sciences and published playwright, is organizing a unique symposium at the upcoming 2010 meeting of the American Association for the Advancement of Science, or AAAS.

Biologists use mathematics to advance our understanding of health and disease
Math-based computer models are a powerful tool for discovering the details of complex living systems.

Better snowfall forecasting
University of Utah scientists developed an easier way for meteorologists to predict snowfall amounts and density -- fluffy powder or wet cement.

Enzyme deficiency protects hepatitis C patients from treatment-related anemia
Many people who undergo treatment for hepatitis C develop hemolytic anemia, a disorder that destroys red blood cells.

Some say the world's population will swell to 9 billion people by 2030, presenting significant challenges for agriculture to provide enough food to meet demand, says University of Idaho animal scientist Rod Hill.

Common gene variant may increase risk for a type of cardiac arrhythmia
An international research team has identified a common gene variant associated with a form of the irregular heartbeat called atrial fibrillation.

The role of sleep in brain development
Marcos Frank, Ph.D., associate professor of Neuroscience at the University of Pennsylvania School of Medicine, will present information on early brain development and the importance of sleep during early life when the brain is rapidly maturing and highly changeable.
