ST. PETERSBURG, Fla. — A high school football player in St. Petersburg, Florida, is brain dead after collapsing during Friday night's game, according to the teen's mother.After a group tackle, 17-year-old Jacquez Welch of Northeast High School never stood back up. Paramedics rushed Welch to Bayfront Hospital where doctors discovered a pre-existing brain condition that no one knew about. They say Jacquez was born with arteriovenous malformation, also known as AVM. It's an abnormal connection between the arteries and veins in the brain. Marcia Nelson, his mother, was in the stands when it happened. She said in a press conference Monday that her son is brain dead and his collapse had nothing to do with the sport."I don't want anybody to be scared of sports," Nelson said. "It just happened to him at an early age, doing what he loved to do."Nelson said the family is working on making her son an organ donor to seven people. The family plans to take Jacquez off life support Monday night after an honor walk at 10 p.m. at Bayfront Hospital. "I am content. This is not anything I could control," Nelson said calmly. Nelson said Jacquez was a giving person and he would be proud that his organs will be used to save other lives. Nelson says football was his passion. He was also an older brother who served as a role model for his siblings. 1358

Since it landed on Mars in 2012 NASA's Curiosity rover has been exploring Gale Crater, a vast, dry ancient lake bed with a mountain at its center. Now, Curiosity has found sediments containing sulfate salt in the crater, which suggest it once held salty lakes.A range of salts have been found on Mars in different locations. Researchers interpret these as evidence of ancient brines. Salty water formations seemed to increase on the Martian surface as the planet transitioned to an arid climate 3.5 billion years ago.The new detection of sulfate salts came from sedimentary rocks dated to between 3.3 and 3.7 billion years ago. Curiosity has analyzed other, older rocks on Mars and didn't detect these salts in them.Researchers believe the salt is evidence of the crater's lake evaporating in the Red Planet's arid environment. They also believe studying younger rocks in the future could shed more light on how the Martian surface dried out.Gale Crater was created by an ancient impact, then filled in with sediment layers over time. Mount Sharp, the mountain at its center, was created by wind erosion of the hardened sediment layers. Those same layers act like chapters in the history of Mars and provide clues to its environment at each point in time.At the time the sulfate salts were present, lakes were probably scattered across the crater floor, fed by streams in the crater walls. Over time, the streams would overflow and then evaporate, trapped in a repetitive cycle taking place over millions of years.The findings were published Monday in the journal 1576
