(CNN) -- Police in Tennessee arrested a man named Tupac A. Shakur, 40, after they say he pulled a knife on them and was found with methamphetamine.Officers with the Johnson City Police Department, about 25 minutes from Bristol, received calls Friday about Shakur who had active warrants for his arrest from another department, according to a news release from Johnson police.When officers arrived at the scene, they saw a car with Shakur inside. Officers attempted to arrest Shakur, but he pulled away and reached for his waistband, the release said.Shakur then turned toward officers with a knife before officers took him down. Officers found a syringe and baggies of meth on Shakur, the release said.Shakur was charged with aggravated assault, simple meth possession and having unlawful drug paraphernalia. He is being held at the Washington County Detention Center on a ,000 bond. He is set to be arraigned Monday, the release said.It was not clear Sunday whether Shakur has legal representation.Shakur shares the same name, even the same middle initial, as the late rapper Tupac Shakur who was killed in September 1996 at age 25. 1144

(CNN) -- Lifeguards in Huntington Beach, California, were reminding swimmers to shuffle their feet when they go into the ocean after 176 people were stung by stingrays in just one day.A record number of people were stung on Saturday, authorities told CNN affiliate KTLA.It may sound like a scene from a monster movie, but the rays weren't on a stabby rampage attacking beachgoers' lower legs.Warm weather brought lots of people to the beach during low tide."When you have people in the water with lower tides like that, they make their way out to where the stingrays reside and, unfortunately, people step on the stingrays and that's when they get stung," Lt. Eric Dieterman of the fire department's Marine Safety Division told KTLA.Lifeguards had people soak their injuries in bags of warm water to help ease the pain from the stings.There were fewer people in the water on Sunday after the weather got cooler, KTLA reported, and the number of stings went down.Dieterman said lifeguards warned people to stay out of the water through Monday.Stingrays are flat, bottom-dwellers that like to hang out partially covered in the sand in shallow, temperate waters.Their primary defense is camouflage, but they will sting if stepped on or disturbed. That's why experts recommend swimmers shuffle their feet when they walk in the water to produce vibrations that scare the rays away.Stingray injuries can usually be treated with warm water, antibiotics to prevent infections and possibly a tetanus shot, according to SeaGrant California. In rare cases, a doctor may have to remove a stinger if it breaks off in the wound.Legendary television star and conservationist Steve Irwin died in 2006 when a stingray barb went into his chest while he was filming a documentary in Australia.Huntington Beach resident Lee Perkins told KTLA that he was stung two weeks ago and that the wound got infected."It's definitely a searing nerve pain and it's pretty intense," Perkins said.Perkins said he's grateful that his 10-year-old son, who was swimming nearby, wasn't stung. 2062

(KGTV) - Is cell phone use causing young people to grow horns on the back of their skulls?That is unproven.Research published this month claims people are developing horn-like spikes on the back of their skulls because they're tilting their heads forward while looking at phones or tablets.But the New York Times points out the study lacked a control group.Two surgeons also told the paper that bone spurs from leaning forward aren't nearly as big a deal as possible disc disease, neck misalignment, and permanent changes in posture.This question was submitted to us by Alanna Cate from Sabre Springs. 609
