12:10a	What Cardiologists Think About the Apple Watch's Heart-Tracking Feature An anonymous reader quotes a report from SFGate: The newest Apple Watch can now flag potential problems with your heartbeat -- a feature that's been cleared by the Food and Drug Administration and that Apple is marking as a major achievement. But some doctors said that including heart-monitoring tools in such a popular consumer product could prompt unnecessary anxiety and medical visits. Physicians say the watch could be good for patients who have irregular heart rhythms but may not realize it. Some people who have atrial fibrillation, the condition for which the watch is screening, don't always have noticeable symptoms. In an ideal situation, someone who doesn't know they have a problem could get a warning from their watch and take that data to their doctor. But there is also concern that widespread use of electrocardiograms without an equally broad education initiative could burden an already taxed health-care system. Heart rhythms naturally vary, meaning that it's likely that Apple Watch or any heart monitor could signal a problem when there isn't one -- and send someone running to the doctor for no reason. "People are scared; their heart scares them," John Mandrola, a cardiologist at Baptist Health in Louisville, said. "That leads to more interaction with the health-care system." An extra visit to your doctor may not sound like a bad thing, but Mandrola said it would potentially lead to another round of tests or even unnecessary treatment if there are other signs that can be misinterpreted. And doctors might wind up facing a crowd of anxious Apple Watch users getting false signals -- something physicians have already had to deal with as fitness trackers that monitor heart rates have become popular.

10:00a	Nvidia Scanner Brings One-Click Overclocking To Its GeForce RTX Graphics Cards Nvidia's new "Scanner" tool for the company's newest GeForce RTX 2080 graphics cards will provide one-click overclocking. PCWorld reports: Nvidia Scanner isn't actually a tool you can download. Instead, it's an API that developers can implement, similar to how current GeForce overclocking software relies on Nvidia's NVAPI. Tom Peterson, Nvidia's director of technical marketing, says all of the major overclocking programs will implement Scanner. You simply press the Test button, and the software starts walking through your graphics card's volt frequency curve, running arithmetic tests all the while. If the overclock starts pushing too far, Nvidia Scanner will discover a math error before your card crashes. When that happens, Scanner ramps up your card's voltage and starts testing again. After about 20 minutes, Scanner will have a complete understanding of your RTX card's capabilities, and automatically generate an overclocking profile built to squeeze as much performance as possible out of it without crashing. Easy-peasy. PCWorld's Brad Chacos mentions a demonstration where "Nvidia's Tom Peterson showed Nvidia Scanner pushing the GeForce RTX 2080 -- which ships with a 1,710MHz boost clock -- all the way to 2,130MHz at 1,068mV."

11:34p	To Fight Climate Change, California Says 'We're Launching Our Own Damn Satellite' An anonymous reader quotes the Los Angeles Times: Jerry Brown closed his climate summit in San Francisco on Friday with a dramatic announcement: California will launch its own satellite into orbit to track and monitor the formation of pollutants that cause climate change. "With science still under attack and the climate threat growing, we're launching our own damn satellite," Brown said in prepared remarks. "This groundbreaking initiative will help governments, businesses and landowners pinpoint -- and stop -- destructive emissions with unprecedented precision, on a scale that's never been done before...." The state will develop the satellite with the San Francisco-based Earth-imaging firm Planet Labs, a company founded by former NASA scientists in 2010. The state may ultimately launch multiple satellites into space, according to the governor's office.... Robbie Schingler, co-founder of Planet Labs, said the project will inform "how advanced satellite technology can enhance our ability to measure, monitor, and ultimately, mitigate the impacts of climate change..." Brown's announcement came in quickly delivered remarks at the close of the three-day gathering and received a standing ovation from many in the audience. Governors from 17 states (and from both political parties) also pledged to spend $1.4 billion to lower auto emissions, using money from Volkwagen's legal settlement over falsifying clean-air performance data. New York City also announced that its pension fund would invest $4 billion in companies offering climate change solution over the next three years. And 26 states, cities and businesses said they'd procure non-polluting vehicle fleets by 2030, while ChargePoint and EV Box pledged to build 3.5 million new charging stations around the world.
