For more than a decade, Dawn Comstock has studied sports injuries among high school athletes, collecting data from hundreds of high schools across the country.She says after going over all the numbers, something began to stand out about men and women’s lacrosse.“We really just set out to ask the question, "how much of the concussions of girls lacrosse could be directly attributed to the fact that they are prohibited from wearing the hard shell helmet with the full facemask that’s required in boys lacrosse?" said Comstock.Ann Kitt Carpenetti from US Lacrosse says the differences create almost a different game with different issues.“The game rules are different, the culture is different, we do recognize that injuries do occur in both games," said Carpenetti.There’s no body checking, basically a running shove, in women’s lacrosse like there is in the men’s game. Because of that rule, women's lacrosse players don't wear helmets.But Comstock and fellow professor Sarah Fields found that rule isn't keeping female players from getting hurt.“What we found was 72.7% of all of the concussions among girls high school lacrosse players resulted from being struck by a stick or a ball," said Comstock.Almost three quarters of concussions among women's players have nothing to do with player-to-player contact.The researchers estimated that by requiring them to wear helmets, they could reduce the total concussions in the sport by 45%“61.5% of the concussions that resulted from being hit by the stick or the ball in girls lacrosse players could have been prevented if they had been wearing the same helmet the hard shell helmet with the full facemask that boys lacrosse players are required to wear,” said Comstock.US Lacrosse says it has a helmet designed for women’s lacrosse and is testing it in Florida“In terms of the rate of head injuries caused by stick and ball, some concussive, some other, we agree it was notable. And that’s why we led the development of the ASTM head gear back in 2008,” said Carpenetti.The helmet is softer and has less coverage than the male helmet, and right now it’s optional in all states except Florida. Depending on the results of an ongoing study of it’s effectiveness it could be rolled out across the country.But for Fields and Comstock, that rollout is inching along at a painful rate."Sport culture, loves to move at a glacial pace, I mean we're still arguing about designated hitters in baseball. So we don't like change in sport and we pretend like change can't happen in sport," said Sarah Fields, CU Denver.Change Comstock and Fields say would help prevent nearly half the concussions in women’s lacrosse. 2662

First it was catastrophic lava. Then it was sulfur dioxide. Now Big Island residents have yet another danger to worry about.Laze -- a mashup of "lava" and "haze" -- is a nasty product formed when hot lava hits the ocean, sending hydrochloric acid and volcanic glass particles into the air.And now it's a real threat after lava crossed Highway 137 late Saturday night and entered the Pacific Ocean, the Hawaiian Volcano Observatory (HVO) said.Laze can cause lung, eye and skin irritation. And it's proven deadly in the past."This hot, corrosive gas mixture caused two deaths immediately adjacent to the coastal entry point in 2000, when seawater washed across recent and active lava flows," the HVO said.Officials are warning people to stay away from areas where lava meets the ocean. But further inland, residents have other problems. 857

For the first time since 2003, the American Heart Association is updating the comprehensive guidelines for blood pressure and hypertension.According to a release from the AHA, patients with a blood pressure reading of 130/80 should now be considered to have hypertension, or abnormally high blood pressure. Previously, a blood pressure level of 140/90 was the baseline for being diagnosed with hypertension.The new guidelines from the AHA mean that nearly half of all American adults — 46 percent — suffer from hypertension. By the AHA’s old standards, 32 percent of American adults suffered from high blood pressure. “We want to be straight with people – if you already have a doubling of risk, you need to know about it,” said Dr. Paul K. Whelton, the lead author of the AHA’s new guidelines. “It doesn’t mean you need medication, but it’s a yellow light that you need to be lowering your blood pressure, mainly with non-drug approaches.”Despite an increase in the amount of Americans with high blood pressure, the AHA hopes their new guidelines mean there will be only a small increase in the amount of patients requiring medication. The Association now generally recommends that patients with Stage 1 hypertension only be prescribed medication in the event of a heart attack or stroke, and they’re also recommending that pharmaceutical companies combine multiple blood pressure drugs. The AHA also hopes the new guidelines encourage patients to monitor their blood pressure at home, away from a stressful setting like a doctor’s office that can skew a single blood pressure test.According to the AHA, the new guidelines were developed by 21 science and health experts who reviewed more than 900 published studies.The new AHA guidelines for diagnosing hypertension are listed below. 1803

Former Trump campaign adviser Roger Stone told associates he was in contact with WikiLeaks founder Julian Assange in 2016, according to a new report by The Washington Post, which cites two sources.An unnamed source told the Post that Stone had a phone conversation with Assange in the spring of 2016. Ahead of any public knowledge about Democratic email leaks, Stone told the source he had learned WikiLeaks had obtained emails from the Democratic National Committee and Democratic presidential nominee Hillary Clinton's campaign chairman, John Podesta.During the campaign, Stone said in interviews and speeches that he was in touch with WikiLeaks, and he posted tweets in October 2016 that seemingly predicted the Podesta leaks. The Washington Post report suggests that in addition to these public statements, Stone was even more candid in private conversations about ties to WikiLeaks. 895
