SAN RAMON, Calif. (AP) — Apple is introducing a cheaper version of its smartwatch, its latest attempt to broaden the appeal of its trend-setting products while more consumers are forced to scrimp during ongoing fallout from the pandemic. The scaled-down Apple Watch follows a budget iPhone that came out five months ago as the pandemic caused unemployment rates to soar. Apple took the wraps off the new discount watch in addition to a new high-end model, a next-generation iPad and a new subscription service during a virtual event held Tuesday. The company normally also rolls out its new iPhones at this time of year, but production problems caused by the pandemic have delayed their release until at least October, the Associated Press reports.CEO Tim Cook didn’t mention iPhones during Tuesday’s one-hour presentation recorded at the company’s massive, but now mostly empty, headquarters in Cupertino, California.The Apple Watch has never come close to rivaling the iPhone’s popularity, but it does dominate the market for smartwatches.The new discount model, called the Apple Watch SE, will sell for 9 and be available beginning Friday. The price is a markdown from the 9 that Apple is asking for the next version of its higher end watch, the Series 6.Apple added more features to help the watch monitor its owner’s health, including a sensor that can read blood oxygen levels. The feature, specific to the Series 6, could be timely, given that COVID-19 frequently attacks the lungs.Apple also announced a new fitness subscription service tailored for its watches for per month, as well as a new option that will bundle its existing music, video, news and gaming services into a package that will cost to per month. 1747

SAN FRANCISCO (AP) -- San Francisco has banned all tobacco smoking inside apartments, citing concerns about secondhand smoke. But lighting up a joint inside? That's still allowed.The San Francisco Chronicle reports the Board of Supervisors voted 10-1 Tuesday to approve the ordinance making San Francisco the largest city in the country to ban tobacco smoking inside apartments.The original proposal sought to ban residents from smoking marijuana in their apartments. But supervisors voted to exclude marijuana after cannabis activists said the law would take away their only legal place to smoke.It's illegal under state law to smoke cannabis in public places. 669

Scientists are tracking an object heading toward earth that could enter the planet’s orbit, and they are not entirely sure what it is.The object, named Asteroid 2020 SO, is believed to be man made and not a piece of moon or other planetary debris."I suspect this newly discovered object 2020 SO to be an old rocket booster because it is following an orbit about the Sun that is extremely similar to Earth's, nearly circular, in the same plane, and only slightly farther away (than) the Sun at its farthest point," Dr. Paul Chodas, the director of NASA’s Center for Near Earth Object Studies, told CNN."That's precisely the kind of orbit that a rocket stage separated from a lunar mission would follow, once it passes by the Moon and escapes into orbit about the Sun. It's unlikely that an asteroid could have evolved into an orbit like this, but not impossible,” Dr. Chodas continued.Other publications believe the object could be from Surveyor 2, which was launched in September 1966.Scientists are estimating 2020 SO will enter earth’s orbit in November 2020, then pass by earth at a distance of roughly 30,000 miles in December, before heading back out to space in early 2021.For perspective, commercial planes fly at an altitude of about 7 miles on average.There is no danger to earth posed by 2020 SO, but its slow speed and relatively close pass-by, means scientists can study it. It’s also a reminder that objects sent into space remain in space. 1461

  

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

  

SANTA ANA, Calif. (AP) — In the latest move to change place names in light of U.S. racial history, leaders of Orange County’s Democratic Party are pushing to drop film legend John Wayne’s name, statue and other likenesses from the county’s airport because of his racist and bigoted comments.The Los Angeles Times reports that earlier this week, officials passed an emergency resolution condemning Wayne’s “racist and bigoted statements” made in a 1971 interview and are calling on the Orange County Board of Supervisors to drop his name, statue and other likenesses from the international airport.In the Playboy magazine interview, Wayne makes bigoted statements against Black people, Native Americans and the LGBTQ community. 734
