Researchers hit back at early bodycheck theory

2012-07-13
(Press-News.org) (Edmonton) A new study from the University of Alberta is challenging the notion that teaching the next generation of Sidney Crosbys how to take a bodycheck at an earlier age will help them avoid injury over the long term.

Researchers with the Alberta Centre for Injury Control and Research in the School of Public Health studied hockey-related injuries using data from several emergency departments in the Edmonton region. They found little truth to the theory that introducing bodychecking at an earlier age helps prevent injuries because players gain an "instinctive ability" to protect themselves—a popular convention in minor-hockey circles.

"The effects of injuries in hockey can be long-lasting. Whether they're severe fractures or intracranial injuries, there are long-term consequences—you can heal a broken arm but you can't necessarily heal a brain injury," said study co-author Andrew Harris.

"Our results showed that introducing bodychecking earlier does not reduce these risks. We did not find significantly different injury rates for serious injuries such as fractures or head and neck injuries, or any intracranial injury."

Harris worked with Donald Voaklander, director of the Alberta Centre for Injury Control and Research, to evaluate emergency records for two groups of youth aged nine to 15 years playing atom, peewee and bantam hockey—8,000 in total.

The first group played from 1997 to 2002, when children as young as 12 and 13 in the peewee division were taught to bodycheck. Researchers then compared injury rates with those among players from 2003 to 2010, after a rule change that saw players as young as 11 and 12 learn to bodycheck.

The research team found no significant differences in the number of fractures, head injuries and neck injuries among peewee and bantam players across both groups.

No significant differences were observed in the atom division, where no hitting was allowed across all playing seasons.

Voaklander said this study, along with existing research elsewhere in Canada, clearly shows practice does not make perfect when it comes to doling out and receiving bodychecks and avoiding injury.

"It really does not have much merit," he said. "Exposing 11- and 12-year-olds to bodychecking is not helping matters at the upper level, so there is no point in continuing it."

Voaklander said the only proven way to reduce the risk for Canada's hockey-playing youth is to avoid contact. That's always been a controversial issue in hockey circles, and a stumbling block for the public health community, he added, but the evidence is getting harder to ignore.

"The body of knowledge is building. Sooner or later there is going to be a tipping point. The people making the rules are going to have to make the right choice."

The study was published in June by the Clinical Journal of Sport Medicine in an early online release.

New Notre Dame research raises questions about iris recognition systems

2012-07-13
Since the early days of iris recognition technologies, it has been assumed that the iris was a "stable" biometric over a person's lifetime — "one enrollment for life." However, new research from University of Notre Dame researchers has found that iris biometric enrollment is susceptible to an aging process that causes recognition performance to degrade slowly over time. "The biometric community has long accepted that there is no 'template aging effect' for iris recognition, meaning that once you are enrolled in an iris recognition system, your chances of experiencing ...

The ecology of natural gas

2012-07-13
"Fracking" stories about shale gas extraction hit the news daily, fueling a growing conflagration between environmental protectionism and economic interests. Otherwise known as hydraulic fracturing, fracking has become a profitable venture thanks to advances in horizontal drilling technology, opening up large US reservoirs and vastly changing the natural gas market. Touted as a clean energy source and a bridge fuel to transition from fossil fuels, natural gas via fracking is also frought with public health and environmental concerns. A session at the upcoming annual ...

Antarctica faces major threats in the 21st century, says Texas A&M researcher

2012-07-13
The continent of Antarctica is at risk from human activities and other forces, and environmental management is needed to protect the planet's last great wilderness area, says an international team of researchers, including a Texas A&M University oceanographer, in a paper published in the current issue of Science magazine. Mahlon "Chuck" Kennicutt II, professor of oceanography who has conducted research in the area for more than 25 years, says Antarctica faces growing threats from global warming, loss of sea ice and landed ice, increased tourism, over-fishing in the region, ...

Large, medically important class of proteins starts to yield its secrets

2012-07-13
LA JOLLA, CA – July 12, 2012 –Readers of the top-ranked scientific journals Science and Nature might have noticed a recent wave of articles, most recently in the July 13, 2012 issue of Science, with deep importance for biology and medicine. These papers, all published this year by collaborations headed by the Scripps Research Institute laboratory of Professor Raymond Stevens, illuminate a large and medically important family of proteins called G protein-coupled receptors (GPCRs). GPCRs sit in the cell membrane and sense various molecules outside the cell, including odors, ...

First ever videos of snow leopard mother and cubs in dens recorded in Mongolia

2012-07-13
New York, NY – For the first time, the den sites of two female snow leopards and their cubs have been located in Mongolia's Tost Mountains, with the first known videos taken of a mother and cubs, located and recorded by scientists from Panthera, a wild cat conservation organization, and the Snow Leopard Trust (SLT). Watch the videos and view a photo gallery. Because of the snow leopard's secretive and elusive nature, coupled with the extreme and treacherous landscape which they inhabit, dens have been extremely difficult to locate. This is a tremendous discovery and ...

Messy experiment cleans up physics mystery of cornstarch

Click here for more information. Most people buy cornstarch to make custard or gravy, but Scott Waitukaitis and Heinrich Jaeger have used it to solve a longstanding physics problem with a substance known to generations of Dr. Seuss readers as "Oobleck," and to scientists as a non-Newtonian liquid.

Tannins in sorghum and benefits focus of university, USDA study

2012-07-13
MANHATTAN, Kan. -- They might be called a blessing or a curse -- tannins, which are present in certain sorghums, contain health-promoting antioxidant properties, but also provide a bitter taste and decreased protein digestibility. To better understand tannins, their role in sorghum and how they can be altered to improve sorghum's use as food and feed, a team of scientists led by Kansas State University and U.S. Department of Agriculture researchers, has cloned the tannin gene in sorghum. Tannins' high antioxidant, anti-inflammatory and UV-protective functions promote ...

Noninvasive imaging technique may help kids with heart transplants

2012-07-13
Cardiologists at Washington University School of Medicine in St. Louis have developed a noninvasive imaging technique that may help determine whether children who have had heart transplants are showing early signs of rejection. The technique could reduce the need for these patients to undergo invasive imaging tests every one to two years. The new method is described online in the Journal of Heart and Lung Transplantation. The invasive imaging test, a coronary angiogram, involves inserting a catheter into a blood vessel and injecting a dye to look for dangerous plaque ...

Advertisers could target online audiences more efficiently with personality scale, MU study finds

2012-07-13
COLUMBIA, Mo. ¬— Online advertising has become prevalent in the past five years, and social media sites, such as Facebook, have played a major role. Now, a study at the University of Missouri School of Journalism has developed a method that could help advertisers target online audiences easier by knowing their personality types. Using a new personality scale, researchers determine how people with certain personality types use social media websites. Heather Shoenberger, a doctoral student in the MU School of Journalism, found that those individuals who liked high-risk ...
