A new study about video gamers pretty much shatters the stereotype many people have about them.Researchers at the Queensland University of Technology in Australia conducted what they say is the first study on body mass index from a worldwide sample of e-sports players. What they found surprised even them.“When we went into the study, we were kind of expecting that the gamers would have a much higher BMI than the general population, but what we found was the complete opposite. We found that players tended to have up to 21% more likelihood of being a normal weight,” said lead researcher Michael Trotter.The study included hundreds of participants from 65 countries. It showed gamers were between 9% and 21% more likely to be a healthy weight. Players also drank less and smoked less than the general population.Trotter started the university's e-sports program before he started studying for his PhD. He says he was surprised that serious players focused on their health almost as much as their playing. He says players requested a personal trainer, a dietician, and a sports psychologist.The study also found the healthier players were the better players.“We found that the players who were in the top 10% of all players and we measured up to 2.5 thousand players, it wasn't a small study. We found the top 10% of all players were exercising significantly more than their lower ranked counterparts,” said Trotter.Trotter says the growth of e-sports is huge and future programs will need to look at this study and realize they must focus on the health of players.He also says future research will need to be done on the overall health of e-sports players, such as muscle mass and bone density. 1706

A new report card is out for dozens of fast-food restaurants, and overall, most failed when it comes to serving antibiotic-free beef.Only two of the restaurant chains received an A grade for having no antibiotics in their beef. Those two included the up-and-coming chain BurgerFi and Shake Shack. The remaining top 22 burger chains failed to pass the test. "We know that change can happen,” says Mark Morgenstein, spokesperson for U.S. PIRG, a consumer and health advocacy group. “We just need the market pressure to be applied.”The organization is just one of many pushing for safer foods and antibiotic-free farms.   "The problem starts at the beginning,” Morgenstein says. “It starts on the farm." According to the CDC, it’s estimated drug-resistant superbugs kill 23,000 people in America each year.Just this past year, health groups made progress in getting chains to go antibiotic-free with their chicken."When there was pressure from McDonald’s and KFC and Subway not to use antibiotics in chicken, guess what? People like Tyson, major chicken producers, stopped using antibiotics in chicken."  1134

A University of Florida research unit killed more than 150 birds over the past 10 years, the Gainesville Sun reported, citing U.S. Fish and Wildlife Service documents.The paper says that of the birds killed at the Plant Science Research and Education Unit, 47 were sandhill cranes and 105 were ring-billed gulls.While the Florida sandhill crane isn't considered endangered, it is a threatened species according to the Florida Fish and Wildlife Conservation Commission.Director of the unit, Jim Boyer, told the Sun the cranes and gulls had damaged or eaten crops grown for research, including high-value peanuts part of a breeding study.The unit says it has since decided to use non-lethal means to protect crops from cranes. 732

  

A north Georgia high school teacher was arrested on Wednesday after he barricaded himself in a classroom and fired a shot from his handgun out of a window, police said.No one was injured in the incident at Dalton High School, except for a student who injured an ankle running through the school, police spokesman Bruce Frazier said.The shooting about 85 miles north of Atlanta heightened the already tense debate around guns in schools in the wake of the deadly mass shooting in Parkland, Florida two weeks ago.The incident began about 11:30 a.m. when Randal Davidson, a 53-year-old social studies teacher, refused to let students into his classroom, Frazier said. When the principal put a key in the door in an attempt to enter, Davidson fired a shot from a handgun through an exterior window of the classroom, according to Frazier.The school immediately went into lockdown, and police quickly arrived and evacuated the immediate area around his classroom. After about 30 to 45 minutes, Davidson agreed to surrender to authorities and was taken into custody without further incident, Frazier said.Frazier said there was no evidence that Davidson was trying to fire at anyone."It certainly seemed like he didn't have any intention to harm anybody else," Frazier said.Davidson had been a teacher at Dalton since 2004 and was the play-by-play radio announcer for the high school's football team, Frazier said. Police did not release any explanation as to a possible reason for what happened.President Donald Trump and the National Rifle Association, among others, have proposed that teachers should be allowed to bring firearms into schools to defend against possible attacks. But critics have said arming teachers would create a host of other dangerous side effects -- and pointed to the Dalton shooting as Exhibit A in that argument.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

A panel of three federal judges in North Carolina ruled Monday the state's congressional map is an unconstitutional partisan gerrymander that favors Republicans, and said it may require districts to be redrawn before the November elections.Republicans hold 10 of the state's 13 seats in the House of Representatives, and a redrawn map could put more seats in play for Democrats -- potentially affecting control of the House.The judges acknowledged primary elections have already occurred, but said they were reluctant to let voting take place in districts that courts twice found had been unconstitutionally drawn.The same decision was reached by the court in January, but the Supreme Court declined in June to hear the case and it was sent back for reconsideration. The Supreme Court has never ruled a partisan gerrymander to be unconstitutional, and it passed up three separate opportunities to do so in the last term.The decision Monday could result in an election-year appeal to the Supreme Court. The court is currently evenly split on ideological lines and lacks a ninth justice to tip the scale. The court also traditionally does not approve of judicial actions so close to an election that could affect the outcome. 1231
