UCI researchers create new breed of flightless mosquitoes for dengue control

UCI researchers and colleagues from Oxitec Ltd. and the University of Oxford created the new breed. Flightless females are expected to die quickly in the wild, curtailing the number of mosquitoes and reducing - or even eliminating - dengue transmission. Males of the strain can fly but do not bite or convey disease.

Researchers measure diffusion coefficient of a protein in a primary cilium

A team of researchers led by Peter Calvert (SUNY Upstate Medical University) has, for the first time, measured the diffusion coefficient of a protein in a primary cilium and in other major compartments of a highly polarized cell. The study appears in the March issue of the Journal of General Physiology.

Researchers based in Africa have more comprehensive understanding of malaria: MIM

Organisations supporting medical research in Africa, for example research on malaria, cannot assume that scientific results are independent of time and space. Instead the results reflect the interplay between the research environment, researchers and the study object. This is the result of a dissertation in Theory of Science from the University of Gothenburg, Sweden.

WuXi PharmaTech's Suzhou non-clinical safety testing facility receives AAALAC accreditation

WuXi PharmaTech, a leading pharmaceutical, biotechnology and medical device research and development outsourcing company with operations in China and the United States, announced today that its Suzhou non-clinical safety testing facility received full accreditation from the Association for the Assessment and Accreditation of Laboratory Animal Care International (AAALAC). As a result of an extensive on-site evaluation, AAALAC determined that WuXi PharmaTech's facility meets the highest standards of animal care and research practices.

Prediction of sport injuries through equations

Spanish researchers have developed a new mathematical model that permits to predict sport injuries from a series of equations. Their work has proved that sport injuries that affect the lower limbs in high-impact sport, such as football, athletics or basketball, can be predicted through the use of equations of logistic regression.

Racial disparities in beliefs about lung cancer

A new survey has found that African-Americans are more likely than whites to hold mistaken and fatalistic beliefs about lung cancer, as well as being more reluctant to consult a doctor about possible symptoms of the disease, according to researchers from Dana-Farber Cancer Institute and their collaborators.

Researchers to study how dust particles pose health threat to people

Residents of the southern United States and the Caribbean have seen it many times during the summer months-a whitish haze in the sky that seems to hang around for days. The resulting thin film of dust on their homes and cars actually is soil from the deserts of Africa, blown across the Atlantic Ocean.

Research paves way for building tabletop X-ray laser that can be used for high-resolution imaging

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. And for the past two decades, University of Colorado at Boulder physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal.

Study proposes potential molecular mechanism at play in mild TBI

Douglas Smith, MD, director of the Center for Brain Injury and Repair and professor of Neurosurgery at the University of Pennsylvania School of Medicine, will present information on the molecular mechanism at play in mild TBI (mTBI), commonly called concussions. Although mTBI affects over 1 million people each year in the United States, it is generally ignored as a major health issue. However, this 'mild' form of injury induces persisting neurological and cognitive problems in many of these patients, exacting an enormous emotional and financial toll on society.

Information on early brain development and the importance of sleep during early life to be presented

Marcos Frank, PhD, 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.

WCMC-Q students receive new round of UREP funds totaling $280,000

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

Cash-strapped school districts are making mistake by cutting music from K-12 curriculum: Neuroscientist

At an 11 a.m. press briefing, Saturday, Feb. 20, at the American Association for the Advancement of Science annual meeting, a Northwestern University neuroscientist will argue that music training has profound effects that shape the sensory system and should be a mainstay of K-12 education.

Let babies sleep: Napping supports abstract learning

Anyone who grew up in a large family likely remembers hearing "Don't wake the baby." While it reinforces the message to older kids to keep it down, research shows that sleep also is an important part of how infants learn more about their new world.

Siestas can dramatically boost and restore brain power

If you see a student dozing in the library or a co-worker catching 40 winks in her cubicle, don't roll your eyes. New research from the University of California, Berkeley, shows that an hour's nap can dramatically boost and restore your brain power. Indeed, the findings suggest that a biphasic sleep schedule not only refreshes the mind, but can make you smarter.

Study reveals underrepresentation of women in cardiovascular clinical trials

Women are substantially underrepresented in clinical trials used to formulate women's guidelines and are affected more than men by low social support after a heart attack, according to two studies in the women-themed issue of Circulation: Cardiovascular Quality and Outcomes, a journal of the American Heart Association.

Enzyme can allow nerve cells in brain to grow and form complex networks: Study

Brain researcher Hiroshi Kawabe has discovered the workings of a process that had been completely overlooked until now, and that allows nerve cells in the brain to grow and form complex networks. The study shows that an enzyme which usually controls the destruction of protein components has an unexpected function in nerve cells: it controls the structure of the cytoskeleton and thus ensures that nerve cells can form the tree-like extensions that are necessary for signal transmission in the brain.

Variations among individual organisms attributed to differences in genes, environment or chance

Biologists attribute variations among individual organisms to differences in genes or environment, or both. But a new study of nematode worms with identical genes, raised in identical environments, has revealed another factor: chance.

CMAJ study summarizes risk factors for severe outcome among patients admitted to hospital with H1N1

A new study in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/cgi/doi/10.1503/cmaj.091823 of all patients in Canada admitted to hospital for H1N1 in the first five months of the outbreak summarizes the risk factors for a severe outcome (www.cmaj.ca). The H1N1 pandemic presents important learnings for clinicians and researchers and data on severe outcomes can help inform future treatment and prevention guidelines.

Study analyzes genome and exome sequence data from hunter-gatherer participants of South Africa

In a study published online today in Nature, a team of researchers from Penn State University and the University New South Wales present the complete genome sequences of an indigenous hunter-gatherer from the Kalahari Desert and a Bantu from southern Africa, along with three additional whole exome sequences of Kalahari hunter-gatherers.

Mechanism by which Plasmodium replicates itself in human blood to spread disease identified

Malaria remains one of the most deadly infectious diseases. Yet, how Plasmodium, the malaria parasite, regulates its infectious cycle has remained an enigma despite decades of rigorous research.
