Why binge drinkers are slower to heal from their wounds
2014-04-08
MAYWOOD, Ill. – People who are injured while binge drinking are much slower to heal from wounds suffered in car accidents, shootings, fires, etc.
Now a new study is providing insights into why alcohol has such a negative effect on wound healing. Loyola University Chicago Stritch School of Medicine researchers report that binge alcohol exposure significantly reduced levels of key components of the immune system involved in healing.
The study by senior author Katherine A. Radek, PhD, and colleagues from Loyola's Alcohol Research Program and the Infectious Disease and ...
Global health funding reaches new high as funding priorities shift
2014-04-08
Washington, D.C.—Global health funding hit an all-time high of $31.3 billion in 2013, five times greater than in 1990. Yet with 3.9% growth from 2012 to 2013, the year-over-year increase falls short of the rapid rates seen over the previous decade, according to new research by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington being published online in a web first edition on April 8 by Health Affairs.
As funding from many bilateral donors and development banks has declined, growth in funding from the GAVI Alliance, the Global Fund ...
UNC researchers find genetic trigger for RSV-induced infant hospitalizations
2014-04-08
April 8, 2014 CHAPEL HILL, N.C. – Researchers at UNC School of Medicine have pinpointed a viral protein that plays a major role in making respiratory syncytial virus (RSV) the most common cause of hospitalization in children under one year of age.
The discovery, published April 8 in the Journal of Clinical Investigation, is the first step toward identifying better diagnostics and potential treatments for an infection that strikes nearly all children before they reach the age of three and causing severe disease in 3 percent of infected children. RSV infection leads to ...
The double whammy of multiple sex partners and drinking in HIV/STI prevention
2014-04-08
PHILADELPHIA (April 8, 2014) – The cartoon character Homer J. Simpson once said "Alcohol: The source of, and solution to, all of life's problems."
The sage of the ubiquitous and fictional town of Springfield may have hit the nail on the head when it comes to human immunodeficiency virus (HIV) and sexually transmitted infections (STIs) counseling and prevention. The more you drink and/or the more sex partners you have, the less likely you are to engage in HIV-prevention programs.
This rather grim assessment came about from the study, "Barriers to accessing HIV-prevention ...
Language structure… you're born with it
2014-04-08
Humans are unique in their ability to acquire language. But how? A new study published in the Proceeding of the National Academy of Sciences shows that we are in fact born with the basic fundamental knowledge of language, thus shedding light on the age-old linguistic "nature vs. nurture" debate.
THE STUDY
While languages differ from each other in many ways, certain aspects appear to be shared across languages. These aspects might stem from linguistic principles that are active in all human brains. A natural question then arises: are infants born with knowledge of how ...
Advanced warning systems increase safety at intersections, study shows
2014-04-08
Most drivers have experienced a traffic signal that turns yellow just as they approach an intersection, which makes it difficult for them to decide whether to stop or proceed through it. The wrong choice in this situation, known as the "dilemma zone," may lead to crashes, especially at high-speed intersections.
A major factor making driving difficult is hazards that are sudden and hard to predict. Roadside and in-vehicle display warning systems may help drivers handle these hazards by predicting their occurrence and providing advanced warning to the driver, according ...
Lipid levels during prenatal brain development impact autism: York U study
2014-04-08
In a groundbreaking York University study, researchers have found that abnormal levels of lipid molecules in the brain can affect the interaction between two key neural pathways in early prenatal brain development, which can trigger autism. And, environmental causes such as exposure to chemicals in some cosmetics and common over-the-counter medication can affect the levels of these lipids, according to the researchers.
"We have found that the abnormal level of a lipid molecule called Prostaglandin E2 in the brain can affect the function of Wnt proteins. It is important ...

Phase II trial of efatutazone shows challenge of matching treatment to population
2014-04-08
Work at the University of Colorado Cancer Center led to phase II trial of efatutazone with erlotinib in patients with refractory non-small cell lung cancer. Results are reported today at the American Association for Cancer Research (AACR) Annual Meeting 2014. While efatutazone did not improve the efficacy of erlotinib in this trial, researchers hope lessons from the trial will allow them to make better future use of the drug or other drugs in its class.
"In oncology and especially in lung cancer, everything is personalized. We're exploring different molecular markers ...
Glucosamine promotes longevity by mimicking a low-carb diet
2014-04-08
Glucosamine has been freely available in drugstores for many decades. It is widely used to treat arthritis and to prevent joint degeneration. Moreover, glucosamine is known to delay cancer growth. In addition, glucosamine reduces metabolism of nutritive sugars, as was already shown some 50 years ago.
In 2007, Michael Ristow showed that too much nutritive sugar shortens the lifespan of roundworms, a widely studied model organism in ageing research. Conversely, impairing carbohydrate metabolism in these worms was capable of extending lifespan [reference 1]. Unfortunately, ...
Future computers that are 'normally off'
2014-04-08
WASHINGTON D.C., April 8, 2014 -- If a research team in Japan gets its wish, "normally off" computers may one day soon be replacing present computers in a move that would both eliminate volatile memory, which requires power to maintain stored data, and reduce the gigantic energy losses associated with it.
Most parts of present computers are made with volatile devices such as transistors and dynamic random access memory (DRAM), which loses information when powered off. So computers are designed on the premise that power is "normally on."
Back in 2000, the concept of ...
Is the power grid too big?
2014-04-08
WASHINGTON D.C., April 8, 2014 -- Some 90 years ago, British polymath J.B.S. Haldane proposed that for every animal there is an optimal size -- one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing or hibernating. Today, three researchers are asking whether there is a "right" size for another type of huge beast: the U.S. power grid.
David Newman, a physicist at the University of Alaska, believes that smaller grids would reduce the likelihood of severe outages, such as the 2003 Northeast ...
Rice U. study: Creativity and innovation need to talk more
2014-04-08
HOUSTON – (April 8, 2014) – Creativity and innovation are not sufficiently integrated in either the business world or academic research, according to a new study by Rice University, the University of Edinburgh and Brunel University.
The findings are the result of the authors' review of the rapidly growing body of research into creativity and innovation in the workplace, with particular attention to the period from 2002 to 2013.

Where credit is due: How acknowledging expertise can help conservation efforts
2014-04-08
Scientists know that tapping into local expertise is key to conservation efforts aimed at protecting biodiversity – but researchers rarely give credit to these local experts. Now some scientists are saying that's a problem, both for the local experts and for the science itself.
To address the problem, a group of scientists is calling for conservation researchers to do a better job of publicly acknowledging the role of local experts and other non-scientists in conservation biology.
"For example, in the rainforests of the Yucatán, scientists couldn't even begin to do ...
Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer
2014-04-08
DALLAS – April 8, 2014 – UT Southwestern Medical Center researchers have demonstrated in both cancer cell lines and in mice that blocking critical DNA repair mechanisms could improve the effectiveness of radiation therapy for highly fatal brain tumors called glioblastomas.
Radiation therapy causes double-strand breaks in DNA that must be repaired for tumors to keep growing. Scientists have long theorized that if they could find a way to block repairs from being made, they could prevent tumors from growing or at least slow down the growth, thereby extending patients' survival. ...
What songbirds tell us about how we learn
2014-04-08
This news release is available in French. When you throw a wild pitch or sing a flat note, it could be that your basal ganglia made you do it. This area in the middle of the brain is involved in motor control and learning. And one reason for that errant toss or off-key note may be that your brain prompted you to vary your behavior to help you learn, from trial-and-error, to perform better.
But how does the brain do this, how does it cause you to vary your behavior?
Along with researchers from the University of California, San Francisco, Indian Institute of Science ...

DNA modifications measured in blood signal related changes in the brain
2014-04-08
Johns Hopkins researchers say they have confirmed suspicions that DNA modifications found in the blood of mice exposed to high levels of stress hormone — and showing signs of anxiety — are directly related to changes found in their brain tissues.
The proof-of-concept study, reported online ahead of print in the June issue of Psychoneuroendocrinology, offers what the research team calls the first evidence that epigenetic changes that alter the way genes function without changing their underlying DNA sequence — and are detectable in blood — mirror alterations in brain tissue ...

From learning in infancy to planning ahead in adulthood: Sleep's vital role for memory
2014-04-08
Boston - April 8, 2014 - Babies and young children make giant developmental leaps all of the time. Sometimes, it seems, even overnight they figure out how to recognize certain shapes or what the word "no" means no matter who says it. It turns out that making those leaps could be a nap away: New research finds that infants who nap are better able to apply lessons learned to new skills, while preschoolers are better able to retain learned knowledge after napping.
"Sleep plays a crucial role in learning from early in development," says Rebecca Gómez of the University of ...
