Former President Barack Obama on Wednesday announced his first wave of endorsements for Democratic candidates vying for elected positions up and down the ballot this November.Obama endorsed 81 people for this first wave and is expected to endorse more ahead of the midterm elections. His office said Wednesday that the former president is also expected to campaign in several states for 2018 candidates.His endorsement list includes several people in high-profile races, including Gavin Newsom for governor of California, Stacey Abrams for governor of Georgia and Jacky Rosen for US Senate in Nevada.Former Obama administration officials and campaign alumni were among those who snagged Obama's backing. They include Colin Allred, Andrew Kim, Tom Malinowski, Lauren Underwood, Richard Cordray and Jill Schiller.Obama said in a statement that he is "proud to endorse such a wide and impressive array of Democratic candidates -- leaders as diverse, patriotic, and big-hearted as the America they're running to represent.""I'm confident that, together, they'll strengthen this country we love by restoring opportunity that's broadly shared, repairing our alliances and standing in the world, and upholding our fundamental commitment to justice, fairness, responsibility, and the rule of law," he continued.The 2018 midterms, now less than 100 days away, are largely seen as a referendum on President Donald Trump's first two years in office.Democrats need a net gain of 23 seats to wrest control of the House from Republicans. They need a net gain of two seats to take a Senate majority, although the path to get to that number is difficult.The endorsements add to other recent post-presidential efforts by Obama to shape the political landscape. 1751

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

For the last two decades, support for marijuana has steadily grown. A record 66 percent of respondents in this year's Gallup poll say they support legalizing cannabis, up from 64 percent last year."I think a lot of consumers are coming out of the shadows, and they just feel more comfortable talking about cannabis, learning about cannabis,” says Trey Fisher.Fisher, with Medicine Man dispensary in Denver, Colorado, says particularly of note in 2018, is the emerging client base of women and the elderly. "The elderly, they're just looking for relief,” explains Fisher. “They're just looking for a product that works, and they don't care about the social stigma anymore."Individual dispensaries are certainly seeing growth, but industry insiders say the pot business as a whole is still being held back."It’s still completely illegal under federal law, and that's sort of putting a damper on the whole industry,” says Raza Lawrence, a cannabis law attorney.Lawrence specializes in helping entrepreneurs obtain cannabis licenses. He says if the U.S. would follow Canada in decriminalizing pot on a national level, the business would explode.  “Once that changes, you're going to see a lot more corporations starting to jump into the fray, and its gonna look a lot more like other types of industries," Lawrence says.Both Lawrence and Fisher say that could happen soon, and they believe the move in Canada could put even more pressure on U.S. lawmakers."I think Canada is gonna really expedite that process a little bit," says Fisher. 1556
