By Gene Johnson | Associated Press SEATTLE — Four Democratic-led Western states announced joint recommendations Wednesday about who should be vaccinated for seasonal respiratory viruses, including the flu and COVID-19, saying the Trump administration has jeopardized public health by politicizing the U.S. Centers for Disease Control and Prevention. California, Oregon, Washington and Hawaii early this month formed the West Coast Health Alliance in an effort to combat what they describe as the “weaponization” of federal health agencies to advance anti-vaccine policies , despite decades of scientific research showing that vaccines are safe and effective .

By Maggie Eastland, Bloomberg US lawmakers are asking Futurewei, a subsidiary of the blacklisted Chinese firm Huawei Technologies Co., to explain why it shared buildings in Silicon Valley with Nvidia Corp. , thrusting the US chipmaker into the crossfire of an investigation into possible Chinese espionage. A letter penned by Republican Chairman John Moolenaar and Democratic Ranking Member Raja Krishnamoorthi of the House Select Committee on China shows a decadelong history of a shared address for Futurewei Technologies Inc. at Nvidia’s headquarters in Santa Clara, California. The lawmakers say that Futurewei held the prime lease on three buildings at the site before Nvidia acquired full control in 2024. The letter also cites a May filing that shows Futurewei is a subsidiary of Huawei.

By Emma Court, Bloomberg At a church parking lot near Los Angeles, two hazmat-suit-clad workers vacuumed and wiped most of the contents of Elle Schneider’s house. Surrounded by stacked plastic bins of books and clothes, they opened up the drawers of a squat wooden dresser and swabbed the outside of a tall white cabinet. Elle Schneider (Alex Welsh/Bloomberg)  The blaze that ravaged the LA suburb of Altadena in January stopped some 50 feet short of the freelance cinematographer’s home, but its plumes filtered through doors and windows, leaving behind lead and other hazardous substances. “It’s embarrassing and it’s dehumanizing to have to do this in front of the entire neighborhood,” said Schneider, who relied on the makeshift remediation center at the church to clean many of her belongings. “It’s bad enough to have to throw out so much of your stuff.” Months after the smoke from California’s destructive fires cleared from LA skies, residents are still reckoning with a t...

CAPE CANAVERAL, Fla. (AP/MARCIA DUNN) — NASA’s Mars rover Perseverance has uncovered rocks in a dry river channel that may hold potential signs of ancient microscopic life, scientists reported Wednesday. They stressed that in-depth analysis is needed of the sample gathered there by Perseverance — ideally in labs on Earth — before reaching any conclusions. Roaming Mars since 2021, the rover cannot directly detect life. Instead, it carries a drill to penetrate rocks and tubes to hold the samples gathered from places judged most suitable for hosting life billions of years ago. The samples are awaiting retrieval to Earth — an ambitious plan that’s on hold as NASA seeks cheaper, quicker options. Calling it an “exciting discovery,” a pair of scientists who were not involved in the study — SETI Institute’s Janice Bishop and the University of Massachusetts Amherst’s Mario Parente — were quick to point out that non-biological processes could be responsible. “That’s part of the reason why we...

DENVER — The toxic gas eyed as a possible culprit in the deaths of six dairy workers in Colorado’s Weld County in August is an infrequent but potentially dangerous feature of this type of agricultural work, while experts say the number of victims has little precedent in modern American history. First responders reported the fatalities at the Prospect Valley Dairy outside Keenesburg on Aug. 20 were possibly associated with exposure to high levels of hydrogen sulfide , known as H2S, a colorless, flammable and corrosive gas that smells like rotten eggs. Hydrogen sulfide naturally occurs in sewers, manure pits, well water, oil and gas wells and volcanoes. It’s also produced in a number of industries, including mining, tanning, oil and gas refining and certain types of agriculture. Its effects depend on how much of it a person breathes in and for how long. Low levels of H2S can produce headaches or eye, nose and throat irritation. But higher levels can cause nausea, vomiting, shortness...
