Coaches can be a strong influence in preventing football injuries, say researchers

2015-07-17
(Press-News.org) ROSEMONT, IL - Teaching coaches about injury prevention and contact restrictions pays off, say researchers who tracked injury rates among youth football players during the 2014 season.

"With an estimated three million youth aged 7 to 14 years old playing tackle football each year, preventing injuries is key. Our study showed that kids who received a comprehensive education from a coach had fewer injuries," said lead author Zachary Y. Kerr, PhD, MPH of the Datalys Center for Injury Research and Prevention.

Kerr and his team had athletic trainers evaluate and track injuries at each practice and game during the 2014 football season. Players were drawn from four states, including Arizona, Indiana, Massachusetts and South Carolina. Athletes were divided into three education groups: no coach education program (NHUF) (704 players), Heads-Up education and Pop Warner affiliation (HUF-PW) (741 players) and Heads-Up Only players (HUF) (663). The Heads-Up Football coaching education program was developed by USA Football and the Pop Warner Football program instituted guidelines to restrict contact during practice.

A total of 370 injuries were reported during 71,262 athlete exposures. Individuals in the HUF-PW and HUF groups had lower practice injury rates compared to those in the NHUF with 0.97/1000 athlete exposures and 2.73/1000 athlete exposures, respectively, versus 7.32/1000 exposures. The game injury rate for the NHUF group was 13.42/1000 athlete exposures while the HUF-PW was 3.42/1000 athlete exposures. The game rates in the HUF and NHUF groups did not differ. Higher injury rates were typically found in those aged 11 to 15 years compared to those 5 to 10 years old. However, stronger effects related to Heads-Up education and Pop Warner affiliation were seen in the older group. The research was recently published in the Orthopaedic Journal of Sports Medicine.

"Our findings support the need for additional coaching education and practice contact restrictions. Future research should look at how different programs work at various levels of competition and sports," said Kerr.

U of M study explains why hemp and marijuana are different

2015-07-17
Genetic differences between hemp and marijuana determine whether Cannabis plants have the potential for psychoactivity, a new study by University of Minnesota scientists shows. "Given the diversity of cultivated forms of Cannabis, we wanted to identify the genes responsible for differences in drug content," says U of M plant biologist George Weiblen. While marijuana is rich in psychoactive tetrahydrocannabinol (THC), hemp produces mostly a non-euphoric cannabidiol (CBD), but the genetic basis for this difference was a matter of speculation until now. The study was published ...

Nanowires give 'solar fuel cell' efficiency a tenfold boost

2015-07-17
A solar cell that produces fuel rather than electricity. Researchers at Eindhoven University of Technology (TU/e) and FOM Foundation today present a very promising prototype of this in the journal Nature Communications. The material gallium phosphide enables their solar cell to produce the clean fuel hydrogen gas from liquid water. Processing the gallium phosphide in the form of very small nanowires is novel and helps to boost the yield by a factor of ten. And does so using ten thousand times less precious material. The electricity produced by a solar cell can be used ...

New catalyst for selective oxidation of methanol to dimethoxymethane under mild conditions

2015-07-17
This article describes the effect of the preparation method of binary oxide supports (TiO2-Al2O3) on catalytic performance of V2O5/TiO2-Al2O3 catalysts for methanol selective oxidation to dimethoxymethane (DMM). The optimized catalyst exhibits a methanol conversion of 48.9% and a high DMM selectivity of 89.9% at 393 K, superior to V2O5/TiO2 and V2O5/Al2O3 catalysts. Reported by Prof. Gong Jinlong of Tianjin University, the research article titled "Selective Oxidation of Methanol to Dimethoxymethane over V2O5/TiO2-Al2O3 Catalysts" was published on Science Bulletin June ...

A new satellite time transfer method based on two-way common-view comparison

2015-07-17
Time synchronization between ground and satellites is a key technology for satellite navigation system. With dual-channel satellite, a method called Two-Way Common-View (TWCV) satellite time transfer for Compass system is proposed in recent study. The title of the paper related to the study is "The method and experiment analysis of two-way common-view satellite time transfer for compass system", which is written by LIU Li from Beijing Satellite Navigation Center and published in SCIENCE CHINA Physics, Mechanics & Astronomy 2015, 58. The researcher combines both characteristics ...

Physicians testified for tobacco companies against plaintiffs with cancer, Stanford study finds

2015-07-17
Despite scientific evidence to the contrary, a small group of otolaryngologists have repeatedly testified, on behalf of the tobacco industry, that heavy smoking did not cause the cancer in cases of dying patients suing for damages, according to a study by a Stanford University School of Medicine researcher. "I was shocked by the degree to which these physicians were willing to testify, in my opinion in an unscientific way, to deny a dying plaintiff -- suffering the aftermath of a lifetime of smoking -- of a fair trial," said Robert Jackler, MD, professor and chair of ...

Some like it sweet, others not so much: It's partly in the genes

2015-07-17
PHILADELPHIA (July 17, 2015) - A new study from the Monell Center and collaborating institutions suggests that a single set of genes affects a person's perception of sweet taste, regardless of whether the sweetener is a natural sugar or a non-caloric sugar substitute. "Eating too much sugar is often seen as a personal weakness. However, our work suggests that part of what determines our perception of sweetness is inborn in our genetic makeup," said study author Danielle Reed, PhD, a behavioral geneticist at Monell. "Just as people born with a poor sense of hearing may ...

Research shows how to reduce the cost of modern investment strategies

2015-07-17
New research from the University of East Anglia (UEA) shows how investors can significantly reduce the cost of implementing portfolio strategies - in some cases by more than 90 per cent. The study, published today in the journal Financial Review, shows that many modern investment strategies often lead to low returns or even lose money in practice, as they are prone to large trading costs. Such costs include bid-ask spreads, brokerage fees and capital gain taxes and can dramatically affect investment returns, turning an otherwise winning strategy into a losing one. Many ...

Carbon dioxide pools discovered in Aegean Sea

Carbon dioxide pools discovered in Aegean Sea
2015-07-16
The location of the second largest volcanic eruption in human history, the waters off Greece's Santorini are the site of newly discovered opalescent pools forming at 250 meters depth. The interconnected series of meandering, iridescent white pools contain high concentrations of carbon dioxide (CO2) and may hold answers to questions related to deepsea carbon storage as well as provide a means of monitoring the volcano for future eruptions. "The volcanic eruption at Santorini in 1600 B.C. wiped out the Minoan civilization living along the Aegean Sea," said Woods Hole Oceanographic ...

Personalized care for aortic aneurysms, based on gene testing, has arrived

2015-07-16
New Haven, Conn. -- Researchers at the Aortic Institute at Yale have tested the genomes of more than 100 patients with thoracic aortic aneurysms, a potentially lethal condition, and provided genetically personalized care. Their work will also lead to the development of a "dictionary" of genes specific to the disease, according to researchers. The study published early online in The Annals of Thoracic Surgery. Experts have known for more than a decade that thoracic aortic aneurysms -- abnormal enlargements of the aorta in the chest area --run in families and are caused ...
