Experts disclose new details about 300-year-old shipwreck
BOSTON (AP) — A Spanish galleon laden with gold that sank to the bottom of the Caribbean off the coast of Colombia more than 300 years ago was found three years ago with the help of an underwater autonomous vehicle operated by the Woods Hole Oceanographic Institution, the agency disclosed for the first time.
New details about the discovery of the San Jose were released on Monday with permission from the agencies involved in the search, including the Colombian government.
"We've been holding this under wraps out of respect for the Colombian government," said Rob Munier, WHOI's vice president for marine facilities and operations.

Workers plugging energy wells as lava flows nearby
PAHOA, Hawaii (AP) — Authorities were racing Tuesday to close off production wells at a geothermal plant threatened by a lava flow from Kilauea volcano on Hawaii's Big Island. Workers were capping the 11th and last well at the plant to prevent toxic gases from wafting out after lava entered, then stalled, on the property near one of the new volcanic vents.
"Right now, they're in a safe state," Mike Kaleikini, senior director of Hawaii affairs for the Puna Geothermal Venture plant, said of the wells. There also were plans to install metal plugs in the wells as an additional stopgap measure.
The wells run as deep as 8,000 feet (2,438 meters) underground at the plant, which covers around 40 acres (16 hectares) of the 815-acre (329.

The Latest: Hawaii volcano's sulfur dioxide emissions surge
PAHOA, Hawaii (AP) — The Latest on the eruption of Kilauea volcano on Hawaii's Big Island (all times local):
1:55 p.m.
Scientists say sulfur dioxide emissions from Hawaii's Kilauea volcano have more than doubled since the current eruption began.
The increase could boost volcanic smog known as vog, but trade winds are currently carrying most of the gas offshore.
U.S. Geological Survey scientist Wendy Stovall says the volcano is belching 15,000 tons of sulfur dioxide each day from ground vents that have formed since May 3.
She says volumes of the gas spiked when the vents began gushing more lava and rivers of molten rock started streaming toward the ocean over the weekend.

Science and commercial satellites launched from California
LOS ANGELES (AP) — A SpaceX Falcon 9 rocket successfully launched a pair of U.S.-German science satellites and five commercial communications satellites into orbit from California on Tuesday.
The rocket roared off from a pad at Vandenberg Air Force Base at 12:47 p.m. and arced over the Pacific Ocean west of Los Angeles as it headed toward the South Pole.
Its upper stage deployed the research satellites minutes after reaching orbit. The satellites for Iridium Communications' next-generation fleet were released in a process completed a little more than an hour after liftoff.
The Falcon 9's first stage was previously used for a launch from Florida in January. SpaceX did not attempt to recover it this time.

Amazon urged not to sell facial recognition tool to police
SEATTLE (AP) — Amazon's decision to market a powerful face recognition tool to police is alarming privacy advocates, who say the tech giant's reach could vastly accelerate a dystopian future in which camera-equipped officers can identify and track people in real time, whether they're involved in crimes or not.
It's not clear how many law enforcement agencies have purchased the tool, called Rekognition, since its launch in late 2016 or since its update last fall, when Amazon added capabilities that allow it to identify people in videos and follow their movements almost instantly.
