The measles, mumps, and rubella vaccine does not increase the risk of autism and does not trigger autism in children who are at risk, according to a new study of over 650,000 children.Researchers used a population registry to evaluate whether the MMR vaccine increased the risk of autism in children born in Denmark between 1999 and 2010. A total of 657,461 children were followed through August 2013, with the researchers documenting diagnoses of autism spectrum disorder as well as known risk factors including age of the parents, diagnosis of autism in a sibling, preterm birth and low weight at birth.Over 95% of the children received the MMR vaccine, and 6,517 were diagnosed with autism. The MMR vaccine did not increase the risk of autism in children who were not considered at risk for the disorder and did not trigger it in those who were, according to the study, published Monday in the journal 918

The gunman who opened fire at the Gilroy Garlic Festival in Northern California over the weekend likely acted alone, police said Tuesday.He was seen by himself in surveillance footage retrieved from the stores he visited before the shooting, Gilroy Police Chief Scot Smithee told reporters."Our investigation is leading us more and more to believe that there was not a second person involved," Smithee said. "I don't think I could say that with absolute certainty at this point because we're still following up leads."Shortly after the attack, authorities said that they were searching for a second gunman who witnesses said may have been involved in the shooting. But Smithee later said multiple people gave differing descriptions of that person.The shooter, identified as Santino William Legan, 19, cut through a back fence to get into the festival in Gilroy's Christmas Hill Park on Sunday and began shooting at random, Smithee said. Legan killed three people and injured at least 12 others with an assault-style rifle he bought in Nevada weeks earlier, authorities said.Police killed the shooter within a minute of him opening fire.Smithee said authorities found a shotgun in the suspect's car, which was parked just northeast of the park. A bag was recovered with additional ammunition from an area by a creek, the police chief said.After the shooting, the FBI and Mineral County Sheriff's deputies searched a Walker, Nevada, residence believed to be used by the shooter and found several items including empty ammunition boxes, a sack of ammunition casings and a bag containing pamphlets on guns, according to court papers authorities filed with the Hawthorne Justice Court.The mass shooting at the popular food festival in the city about 30 miles southeast of San Jose claimed the lives of 6-year-old Stephen Romero, 13-year-old Keyla Salazar and Trevor Irby, a 2017 college graduate.Authorities continue to seek tips from the public as the investigation progresses. 1985

The chairmen of three House committees subpoenaed Secretary of State Mike Pompeo Friday over his failure to produce answers about Ukraine."Pursuant to the House of Representatives' impeachment inquiry, we are hereby transmitting a subpoena that compels you to produce the documents set forth in the accompanying schedule by October 4, 2019," the chairmen of the House Foreign Affairs, Intelligence and Oversight committees wrote in a letter to Pompeo.In addition to the subpoena, Reps. Adam Schiff, Eliot Engel and Elijah Cummings informed the top US diplomat in a separate letter that they had scheduled depositions for five State Department officials who have been mentioned in relation to the inquiry -- Ambassador Marie "Masha" Yovanovitch, Ambassador Kurt Volker, Deputy Assistant Secretary George Kent, Counselor T. Ulrich Brechbuhl and Ambassador Gordon Sondland.The chairman of the three committees wrote to Pompeo on September 9 with a request for six categories of documents "related to reported efforts by President Trump and his associates to improperly pressure the Ukrainian government to assist the President's bid for reelection."That initial letter requested these materials by September 16. After that deadline was missed, Schiff, Engel and Cummings sent another letter on Monday warning that unless the documents were handed over, "our Committees will have no choice but to move towards compulsory process this week."The State Department had until Thursday to reply.Pompeo has not publicly addressed the State Department's role in Rudy Giuliani's dealings with Ukraine and the State Department has not responded to numerous requests for comment about the situation. 1696

The most distant world ever explored 4 billion miles away finally has an official name: Arrokoth.That means “sky” in the language of the Native American Powhatan people, NASA said Tuesday.NASA’s New Horizons spacecraft flew past the snowman-shaped Arrokoth on New Year’s Day, 3 ? years after exploring Pluto. At the time, this small icy world 1 billion miles (1.6 billion kilometers) beyond Pluto was nicknamed Ultima Thule given its vast distance from us.“The name ‘Arrokoth’ reflects the inspiration of looking to the skies,” lead scientist Alan Stern of Southwest Research Institute said in a statement, “and wondering about the stars and worlds beyond our own.”The name was picked because of the Powhatan’s ties to the Chesapeake Bay region.New Horizons is operated from Johns Hopkins University’s Applied Physics Lab in Laurel, Maryland. The Hubble Space Telescope — which discovered Arrokoth in 2014 — has its science operations in Baltimore.The New Horizons team got consent for the name from Powhatan Tribal elders and representatives, according to NASA. The International Astronomical Union and its Minor Planet Center approved the choice.Arrokoth is among countless objects in the so-called Kuiper Belt, or vast Twilight Zone beyond the orbit of Neptune. New Horizons will observe some of these objects from afar as it makes its way deeper into space.___The Associated Press Health and Science Department receives 1436

The House of Representatives voted by 230-195 on Tuesday to approve .5 billion in aid for the growing crisis at the US southern border -- a vote that followed Democratic infighting over the package and a White House veto threat.House Democratic leaders had worked to quell a progressive rebellion and secured passage after making several updates to the measure in response to concerns within the caucus, but the White House has already said it "strongly opposes" the legislation and it is not clear whether the House and Senate will be able to reach an agreement the President will sign off on.The Senate has a bipartisan bill that would allocate .59 billion for the border crisis and advanced out of the Senate Appropriations Committee on a 30-1 vote last week. But the proposal has significant differences with the House bill, adding to the uncertainty over whether a deal can be reached.The progressive pushback against the bill was an unexpected wrinkle in the race to get the legislation passed and signed into law before a key agency -- the Office of Refugee Resettlement -- runs out of money at the end of the month.That's not the only agency in desperate need of funding to stem the crisis at the border. The funding would also go to help other agencies and help manage the crisis.The Senate still faces uncertainty on when it will pass its own border supplemental bill, which doesn't include some of the policy riders the House bill has and includes money for? the Department of Defense, something that the House doesn't do.In a possible sign that the House and Senate may be able to find common ground, however, Pelosi referred to the Senate legislation as a "good bill," in a House Democratic caucus meeting on Tuesday, according to a senior Democratic aide."The Senate has a good bill," Pelosi said at the meeting, according to the aide, though she then said, "Our bill is much better. But if we are going to prevail we have to have a good, strong vote."But even if the House and Senate can come to an agreement, it's still an open question whether the President will sign off.Sen. Dick Shelby, the Republican chairman of the Senate Appropriations Committee, said on Tuesday that he does not have assurances from the White House that the President will definitely support the Senate bill and sign it into law if it's the proposal that passes. "We don't," Shelby said.In a more than two-hour meeting on Monday night, House Democratic leaders and appropriators faced tough questions from rank-and-file members frustrated by House leadership's strategy and the underlying border spending bill.House Appropriations Chairwoman Nita Lowey, a Democrat from New York, unveiled proposed changes on Tuesday morning to the border aid bill, including strengthening requirements for the care of migrants in government custody and setting a time limit of 90 days for unaccompanied children to stay in temporary shelters.Late Tuesday afternoon, the proposed changes were updated to include additional provisions, including requiring the secretary of Health and Human Services to replace contractors who do not meet "enhanced standards required under the Flores settlement" -- which limits the length of time and conditions under which US officials can detain immigrant children.The White House veto threat, however, made clear that the administration "strongly opposes" the bill and 3396
