Water tubing, a recreational activity in which participants ride an inner tube which is pulled behind a boat by a tow rope, has grown in popularity in recent years. Unfortunately, the number of injuries related to this activity has also increased. According to a new study by researchers at the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital, the annual number of water tubing-related injuries increased 250 percent over the 19-year study period, rising from 2,068 injuries in 1991 to 7,216 injuries in 2009. Given that more ...

Our ability to learn and form new memories is fully dependent on the brain's ability to be plastic – that is to change and adapt according to new experiences and environments. A new study from the Montreal Neurological Institute – The Neuro, McGill University, reveals that DCC, the receptor for a crucial protein in the nervous system known as netrin, plays a key role in regulating the plasticity of nerve cell connections in the brain. The absence of DCC leads to the type of memory loss experienced by Dr. Brenda Milner's famous subject HM. Although HM's memory loss resulted ...

HEALTH – Neutron imaging breast cancer . . . More precise optical imaging is vital for better diagnosis of breast cancer, which strikes one in eight women annually in the United States alone. Researchers at Oak Ridge National Laboratory and the University of Tennessee are using the neutron imaging beam line at ORNL's High Flux Isotope Reactor to evaluate neutron imaging as a powerful new tool for early detection.

COLUMBIA, Mo. ¬— We've all heard that "it's not wise to use a cannon to kill a mosquito." But what if you could focus the cannon's power to concentrate power into a tiny space? In a new study, University of Missouri researchers have demonstrated the ability to harness powerful radioactive particles and direct them toward small cancer ...

By broadly comparing the DNA of children to that of elderly people, gene researchers have identified gene variants that influence lifespan, either by raising disease risk or by providing protection from disease. "This research is the first genome-wide, population-based study of copy number variations in children associated with human longevity," said study leader Hakon Hakonarson, M.D., Ph.D., director of the Center for Applied Genomics at The Children's Hospital of Philadelphia. The study appeared Jan. 30 in the open-access journal PLOS ONE. Copy number variations ...

New York City experienced a historic decline in crime rates during the 1990s, but it was not due to the implementation of CompStat or enhanced enforcement of misdemeanor offenses, according to an analysis by New York University sociologist David Greenberg. The study, which appears in the journal Justice Quarterly, did not find a link between arrests on misdemeanor charges and drops in felonies, such as homicides, robberies, and assaults. In addition, the analysis revealed no significant drop in violent or property crime attributable to the NYPD's introduction of CompStat ...

Gravity affects the ecology and evolution of every living organism. In plants, the general response to gravity is well known: their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight. But how do plants sense gravity and how do they direct or signal their cells to grow in response to it? Although botanists understand a great deal about how this works, a recent article in the recent issue of the American Journal of Botany reviews what we know so far, from mechanical to genetic approaches; it reveals ...

CAMBRIDGE, MA -- A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression. But a new study from MIT, Harvard University, the Broad Institute and Brigham and Women's Hospital reveals, for the first time, that these so-called passenger mutations are not just along for the ride. ...

ANN ARBOR—Women in developed countries survive roughly 10 years longer after a breast cancer diagnosis compared to women in poor-to-middle-income countries, a new University of Michigan study suggests. The report demonstrates the lack of access to good health care faced by women in poor countries, said the study's principal investigator Rajesh Balkrishnan, an associate professor at the U-M schools of Pharmacy and Public Health. Early diagnosis and sustained treatment were the biggest hurdles and also the main indicators of patient survival, he said. Balkrishnan and ...

VIDEO: NIMH's Dr. Maura Furey talks about how a functional brain imaging measure may help predict a patient's response to a rapid-acting experimental antidepressant. Click here for more information. A telltale boost of activity at the back of the brain while processing emotional information predicted whether depressed patients would respond to an experimental rapid-acting antidepressant, a National Institutes of Health study has found. "We have discovered a potential ...

Healthy eating not only promotes growth and development, but also provides important opportunities for children to socialize during meals. A new, comprehensive analysis of feeding behavior in children with autism spectrum disorders (ASD) indicates that these children are five times more likely to have a feeding problem, including extreme tantrums during meals, severe food selectivity and ritualistic mealtime behaviors. Researchers at Marcus Autism Center and the Department of Pediatrics at Emory University School of Medicine conducted a comprehensive meta-analysis of ...

A new NOAA research report finds that both fish populations and commercial and recreational anglers have benefited from "no-take" protections in the Tortugas Ecological Reserve in the Florida Keys National Marine Sanctuary. The report, "An Integrated Biogeographic Assessment of Reef Fish Populations and Fisheries in Dry Tortugas: Effects of No-take Reserves," is the first to evaluate how the 151-square nautical mile Tortugas Ecological Reserve affects the living marine resources of the region and the people whose livelihoods are connected to them. The report's analysis ...

Boston, MA – Having adequate levels of vitamin D during young adulthood may reduce the risk of adult-onset type 1 diabetes by as much as 50%, according to researchers at Harvard School of Public Health (HSPH). The findings, if confirmed in future studies, could lead to a role for vitamin D supplementation in preventing this serious autoimmune disease in adults. The study was published online February 3, 2013 and will appear in the March 1 print edition of the American Journal of Epidemiology. "It is surprising that a serious disease such as type 1 diabetes could perhaps ...

LA JOLLA, CA – February 4, 2013 – A team led by scientists at The Scripps Research Institute (TSRI) has identified specific cellular events that appear key to lupus, a debilitating autoimmune disease that afflicts tens of millions of people worldwide. The findings suggest that blocking this pathway in lupus-triggering cells could be a potent weapon against the disease. In the new study, described in an online Early Edition of the Proceedings of the National Academy of Sciences the week of February 4, 2013, the researchers determined that the absence of a certain type ...

(Edmonton) A University of Alberta polar bear researcher along with eleven international co-authors are urging governments to start planning for rapid Arctic ecosystem change to deal with a climate change catastrophe for the animals. U of A professor Andrew Derocher co-authored a policy perspective in the journal Conservation Letters urging governments with polar bear populations to accept that just one unexpected jump in Arctic warming trends could send some polar bear populations into a precipitous decline. "It's a fact that early sea ice break-up and late ice freeze-up ...

Cyclone Felleng traveled through the Mozambique Channel during the week of Jan. 28, 2013 and emerged south into the Southern Indian Ocean where it transitioned into a cold core low pressure area. NASA's TRMM satellite captured a look at the rainfall rates occurring in Felleng as it was making that transition on Feb. 1. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite flew over Cyclone Felleng on Feb. 1 at 1648 UTC (11:48 a.m. EST) as it was exiting the Mozambique Channel and becoming extra-tropical. TRMM measured a small area of heavy rainfall east of the center ...

COLUMBIA, Mo. – Researchers long have evaluated the roles parents play in children's development. Now, researchers at the University of Missouri have found that mothers' directiveness, the extent to which they try to control the content and pace of young children's play, varies based on the children's ages and the mothers' ethnicities. In addition, the study found that the more directive the mothers were during play, the less engaged children were with them and the more negative emotion the children displayed toward their mothers. "Children flourish when they have opportunities ...

BUFFALO, N.Y. – A five-year study by researchers at three universities has established that providing tangible assistance to others protects our health and lengthens our lives. This, after more than two decades of research failed to establish that the same benefits accrue to the recipients of such help. Principal investigator Michael J. Poulin, PhD, assistant professor of psychology at the University at Buffalo, says, "This study offers a significant contribution to the research literature on the relationship between social environment and health, and specifically to ...

OAK BROOK, Ill. – The underlying medical conditions facing young adults who undergo computed tomography (CT) exams represent a significantly greater health risk than that of radiation-induced cancer from CT, according to a new study published online in the journal Radiology. CT utilization has grown approximately 10 percent annually over the last 15 years in the U.S., raising fears of an increase in radiation-induced cancers. However, discussions of radiation-induced cancer risk often fail to take into account the condition of the patients being imaged, according to ...

San Diego, CA, February 5, 2013 – Electronic nicotine delivery systems (ENDS), or e-cigarettes, debuted in China in 2003 and have since become available globally, particularly through the Internet. While they resemble traditional tobacco cigarettes, they produce fewer toxins in the vapor for the smoker. Still, these novel products have unknown long-term health and addiction consequences, are of varying nicotine content and delivery, and may appeal to nonusers and youth. ENDS have been banned by health authorities in Canada and Australia. Researchers from the United States, ...

A University of British Columbia study of American attitudes toward climate change finds that local weather – temperature, in particular – is a major influence on public and media opinions on the reality of global warming. The study, published today by the journal Climatic Change, finds a strong connection between U.S. weather trends and public and media attitudes towards climate science over the past 20 years – with skepticism about global warming increasing during cold snaps and concern about climate change growing during hot spells. "Our findings help to explain ...
