SAN FRANCISCO, Calif. – Uber is utilizing selfie technology to make sure both its drivers and passengers wear face masks to help prevent the spread of the coronavirus.The ride-sharing company has been requiring drivers and riders to wear masks since May, but only required drivers to use its technology to verify their face coverings.“Before starting to drive passengers or deliver food, they are asked to take a selfie showing their mouth and nose are covered,” Uber wrote in a press release.Now, the requirement is being expanded to passengers as well. If a driver reports that a rider isn’t wearing a mask, the rider will be required to take a selfie with their face covered before they’re able to take another trip with Uber.“With the addition of this new feature, one driver’s feedback can help ensure the safety of Uber for the next driver,” said Uber.The mask verification feature will roll out to the U.S. and Canada by the end of September, and across Latin America and other countries after that.Uber assured that the mask verification tool detects the mask as an object in the photo and does not process biometric information.“As always, riders and drivers are free to cancel a trip, without penalty, if the other person isn’t wearing a mask,” Uber wrote. “As more and more riders and drivers take their ‘second first trip,’ we hope this increased accountability provides more peace of mind.”The additional safety measures are part of Uber's efforts to rebuild a service that has seen ridership plunge by 56% in the company's most recent quarter, The Associated Press reports. 1595

Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere.The research by scientists at Harvard and Yale universities, published in the journal Environmental Research Letters, proposes using a technique known as stratospheric aerosol injection, which they say could cut the rate of global warming in half.The technique would involve spraying large amounts of sulfate particles into the Earth's lower stratosphere at altitudes as high as 12 miles. The scientists propose delivering the sulfates with specially designed high-altitude aircraft, balloons or large naval-style guns.Despite the technology being undeveloped and with no existing aircraft suitable for adaptation, the researchers say that "developing a new, purpose-built tanker with substantial payload capabilities would neither be technologically difficult nor prohibitively expensive."They estimate the total cost of launching a hypothetical system in 15 years' time at around .5 billion, with running costs of .25 billion a year over a 15-year period.The report does, however, acknowledge that the technique is purely hypothetical."We make no judgment about the desirability of SAI," the report states. "We simply show that a hypothetical deployment program commencing 15 years hence, while both highly uncertain and ambitious, would indeed be technically possible from an engineering perspective. It would also be remarkably inexpensive."The researchers also acknowledge potential risks: coordination between multiple countries in both hemispheres would be required, and stratospheric aerosol injection techniques could jeopardize crop yields, lead to droughts or cause extreme weather.The proposals also don't address the issue of rising greenhouse gas emissions, which are a leading cause of global warming.And despite the conviction of the report's authors, other experts were skeptical."From the point of view of climate economics, solar radiation management is still a much worse solution than greenhouse gas emissions: more costly and much more risky over the long run," said Philippe Thalmann of the école Polytechnique Fédérale de Lausanne, an expert in the economics of climate change.David Archer of the Department of Geophysical Science at the University of Chicago said, "The problem with engineering climate in this way is that it's only a temporary Band-Aid covering a problem that will persist essentially forever, actually hundreds of thousands of years for fossil fuel CO2 to finally go away naturally."It will be tempting to continue to procrastinate on cleaning up our energy system, but we'd be leaving the planet on a form of life-support. If a future generation failed to pay their climate bill they would get all of our warming all at once." 2830

SEATTLE — Add marine wildlife to the growing list of life affected by America’s opioid crisis.For the first time, scientists have detected traces of oxycodone in mussels near Seattle, KIRO7 reported. Biologist Jennifer Lanksbury explained whatever people eat and excrete — including opioids — end up in waterways.“It’s telling me there's a lot of people taking oxycodone in the Puget Sound area,” Lanksbury said. Washington Department of Fish and Wildlife officials extracted mussels from clean water and put them in urban areas they wanted to test for contamination. There was enough oxycodone in a Seattle-area bay for the mussels to test positive.The system that filters water catches a lot of contaminants, but it can’t specifically filter out drugs, Kings County Wastewater Management said.“Those are definitely chemicals that are out there in the nearshore waters and they may be having an impact on the fish and shellfish that live there,” Lanksbury said.The data was from a one-time study for prescription drugs in Washington’s waterways, but officials say they will try to get more funding to continue research. 1163

SAN MARCOS, Calif. (KGTV) — For more than 20 years, Casey Rummerfield has been the toast of Halloween in his San Marcos neighborhood.Hours spent throughout the year on handmade electronic displays, decorations, and more turn his Shadow Hills Drive home into a memorable tradition for his neighbors, family, and friends."It's more hours than it is money. The cannon prop is home built," Rummerfield says, pointing to various props, barrels, and displays he has built by hand. "I would say about a thousand [hours] a year is what we put into it."RELATED: Clairemont electrician lights up neighborhood with Halloween displayRummerfield's love for Halloween began as a child, though his talent for delivering some spooky fun started when he moved in on Halloween Day in 1993.Since moving in, what started as a need to actually dress up the house for Halloween has blossomed into providing an annual celebration for the neighborhood.Rummerfield's family and friends have been integral in setting up and keeping the tradition alive. And while his children have grown up and moved out, he says they've taken a lot with them.RELATED: Map: San Diego neighborhoods you'll want to check out on Halloween"My youngest has vowed that when it's my time to retire, she's going to take over," Rummerfield says with a smile. "They've texted me more this month than they have all offseason."Rummerfield says one child is currently at Facebook while the other is studying costume and set design and as a special effects make-up artist — perhaps predictably."[She] got an A on her horror class. Brought me to tears," Rummerfield said gleaming.That enthusiasm for Halloween has carried over to the neighborhood year-after-year, seen in Rummerfield's efforts.RELATED: Halloween family fun, haunted houses, and parties in San Diego"You have to see it to believe it. On Halloween Day, their enthusiasm, their drive, their willingness to come back for the umpteenth year," Rummerfield says. "We've not only had the kids come back, but they've grown up and brought their kids."Which is a little difficult, because it does make us feel old," he added. 2201
