Wildlife officials hunt for bear that killed mountain-biker
HELENA, Mont. (AP) - Wildlife officials set traps, installed wilderness cameras and scouted the woods by helicopter Thursday for the bear that attacked and killed a U.S. Forest Service employee as he rode a mountain bike along a trail outside Glacier National Park. Brad Treat, 38, was knocked off his bike Wednesday after he and another rider apparently surprised the bear - a grizzly, according to initial and still-unconfirmed accounts - in the Flathead National Forest, authorities said. The other rider, a relative of Treat's whose name was not released, went to get help and was not hurt. Bears that attack humans are killed if it is found that they displayed predatory behavior, such as stalking the person, or consumed their victim.

Boris bows out: UK in shock as Johnson drops leadership bid
LONDON (AP) - In a real-life political drama mixing Shakespearean tragedy with "House of Cards," Britain's victorious anti-EU campaigner Boris Johnson saw his chances of leading his country evaporate Thursday after the defection of a key ally. The former London mayor dropped his campaign to become Conservative Party leader and prime minister after Justice Secretary Michael Gove abruptly withdrew his support for Johnson and announced he would run himself. Johnson, a prominent campaigner for Britain's withdrawal from the 28-nation European Union, told a news conference where he was expected to announce his candidacy that the next Conservative leader would need to unite the party and ensure Britain's standing in the world.


Tesla driver killed in crash while using car's 'Autopilot'
WASHINGTON (AP) - The first U.S. fatality using self-driving technology took place in May when the driver of a Tesla S sports car operating the vehicle's "Autopilot" automated driving system died after a collision with a truck in Florida, federal officials said Thursday. The government is investigating the design and performance of Tesla's system. Preliminary reports indicate the crash occurred when a tractor-trailer rig made a left turn in front of the Tesla at an intersection of a divided highway where there was no traffic light, the National Highway Traffic Safety Administration said. The Tesla driver died due to injuries sustained in the crash, which took place May 7 in Williston, Florida, the agency said.


Official: Airport attackers from Russia, Central Asia
ISTANBUL (AP) - As the death toll from the Istanbul airport attack rose Thursday to 44, a senior Turkish official said the three suicide bombers who carried it out were from Russia, Uzbekistan and Kyrgyzstan, and Turkish police raided Istanbul neighborhoods for suspects linked to the Islamic State group. Turkish authorities say all information suggests the Tuesday night attack on Ataturk Airport, one of the world's busiest, was the work of IS, which boasted this week of having cells in Turkey, among other countries. Police raided 16 locations in three neighborhoods on both the Asian and European sides of the city that sprawls across the Bosporus Strait, rounding up 13 people suspected of having links to IS.


Istanbul airport attack victims mourned, honored, praised
ISTANBUL (AP) - An adoring father of his four "princesses." A weeping bride-to-be, bent over her fiance's coffin.

Here are some of their stories: --- Teacher Huseyin Tunc, 28, had a difficult childhood.

The Latest: Biden to NPR: "Bernie is going to endorse her"
Vice President Joe Biden says Sen. Bernie Sanders, who is still technically running for president as a Democrat, will soon back Hillary Clinton. Biden tells National Public Radio that he has "talked to Bernie. Bernie is going to endorse her." Sanders has said he's going to vote for Clinton, but he has not formally endorsed her. The former secretary of state has locked up the delegates required to become the first woman to win a major party's presidential nomination. Sanders was holding out for changes to the Democratic party platform. Sanders' endorsement would be another sign that the Democratic Party, split for more than a year between Sanders' populist surge and Clinton's second bid for the presidency, is mending.


OBAMA LEGACY: Immigration stands as most glaring failure
WASHINGTON (AP) - Hours after the Supreme Court sent his immigration policy into legal limbo, President Barack Obama huddled around a long conference table in the Roosevelt Room with disappointed activists. The president looked out at familiar faces, some teary. It had been a long and tough fight, Obama said, and he had taken some beatings - even from supporters who "whupped on me good." He believed his policies would prevail, according to participants in the meeting, but said it was now up to voters and the next president to take up the baton. And with that, Obama delivered his version of a concession speech on a fight that has frustrated him like few others, roiled the campaign to replace him and is certain to test his successor.


Journey to Jupiter: NASA spacecraft nears planet rendezvous
LOS ANGELES (AP) - Jupiter takes center stage with the arrival next week of a NASA spacecraft built to peek through its thick, swirling clouds and map the planet from the inside out. The solar-powered Juno spacecraft is on the final leg of a five-year, 1.8 billion-mile (2.8 billion-kilometer) voyage to the biggest planet in the solar system. Juno promises to send back the best close-up views as it circles the planet for a year. Jupiter is a gas giant made up mostly of hydrogen and helium unlike rocky Earth and its neighbor Mars. The fifth planet from the sun likely formed first and it could hold clues to how the solar system developed.
