Uber doesn't plan to renew its self-driving vehicle permit in California.The news comes less than two weeks after a self-driving Uber SUV struck and killed 49-year-old Elaine Herzberg as she walked her bicycle across a street in Tempe, Arizona. After the tragedy, the company halted testing of its self-driving cars on roads in North America.Uber's self-driving permit in California goes until March 31 -- and the company said it will let the permit expire."We decided to not reapply for a California DMV permit with the understanding that our self-driving vehicles would not operate on public roads in the immediate future," an Uber spokesperson said in a statement to CNN on Tuesday.Uber's statement comes after several news outlets, including CNN, obtained a letter sent by DMV deputy director and chief counsel Brian Soublet to Uber's public affairs manager, Austin Heyworth on Tuesday regarding its permit.Soublet wrote that if and when Uber applies for a new autonomous vehicle testing permit, it will "need to address any follow-up analysis or investigations from the recent crash in Arizona an may also require a meeting with the department."The news of the letter was first reported by the San Francisco Chronicle.The Tempe Police Department and the National Transportation Safety Board have launched investigations into the crash.Last week, Boston's government asked self-driving companies operating in the city to halt operations while safety procedures are reviewed. On Monday, Arizona officially suspended Uber's self-driving car tests in the state despite that Uber had already paused its operations there. 1643

Two pilots on different aircraft recently reported seeing unidentified flying objects in the airspace near them.A commercial pilot for American Airlines, who was flying a passenger jet Feb. 24 over Arizona, reported to Albuquerque Center air traffic control between 3:30 and 4:15 p.m. local time that an object seen?flying at 40,000 feet was unidentifiable and had a big reflection, according to The Huffington Post. Audio of the conversation between the pilot and?air traffic control was released by the Federal Aviation Administration to a website called The Drive, a product of Time Inc. In it, the jet's pilot is heard saying the UFO was flying the opposite direction of the airplane at least 2,000 to 3,000 feet above the plane.The FAA did not have knowledge of anything expected to fly above the jet when the UFO incident occurred.The pilot was asked whether he thought it was a Google balloon, and he said, "doubtful," The Drive's military and aviation correspondent reported.Another commercial pilot flying nearby at the same time also reported seeing an unidentifiable object, just after the first pilot's report. He said he didn't know what the object was, but it wasn't an airplane, and the path was going the opposite direction of his plane. 1341

TUCSON, Ariz. — A team of researchers at the University of Arizona believe they've found an important clue in the fight against an aggressive form of brain cancer.Glioblastoma is the cancer that killed Sen. John McCain in August and Sen. Ted Kennedy in 2009.People are diagnosed with glioblastoma live, on average, for another 11 to 15 months. Very few survive the disease, so the group of researchers wanted to know why some patients live longer than others.Professor of Radiation Oncology, Dr. Baldassarre Stea, says the clue lies in the RNA of short and long-term patients.The team looked at the genetic variation in about three dozen patients.What they found is a gene called WIF1 is distinctly higher in patients who survive longer, according to Dr. Stea. Those who lack the gene succumb to the disease much quicker. 849
