While temperature changes in the tropics are expected to be much less extreme than those at higher latitudes, tropical species actually have a far greater risk of extinction from just a degree or two of warming, according to the results of the study, detailed in the May 5 issue of the journal Proceedings of the National Academy of Sciences. … [Read more...] about Tropical Trouble: Species to Struggle in Heat
There are good reasons why Facebook doesn’t want to be a media company, and the reasons, he said, are not simply legal or regulatory. It’s also a matter of brand management, talent, revenue, and regulation, in that order. "It’s cooler to be a tech company," he said. And consumers want cool. Tech status helps attract talent. "Legacy media have reputations as bad places to work." As a business model, if defined as media, ad revenue will be scrutinized, and, Mele predicted, "regulation will force them to address how they meet the public sphere, which will increase [employee] headcount and increase rates." … [Read more...] about Facebook won’t call itself a media company. Is it time to reimagine journalism for the digital age?
Crash data should be “captured and available in standard formats on new vehicles equipped with automated vehicle control systems” Manufacturers should “incorporate system safeguards to limit the use of automated control systems to conditions for which they are designed” (and that there should be a standard method to verify those safeguards) Automakers should develop ways to “more effectively sense a driver’s level of engagement and alert when engagement is lacking” Automakers should “report incidents, crashes, and exposure numbers involving vehicles equipped with automated vehicle control systems” While Tesla helped the NTSB recover and process the data from Huang’s car, the company is still far more protective of its crash data than other manufacturers. In fact, some owners have sued to gain access to that data. And while Tesla increased the frequency of Autopilot alerts after Huang’s crash, it largely hasn’t … [Read more...] about Tesla Autopilot’s role in fatal 2018 crash will be decided this week
Tesla is once again asked to add safeguards to Autopilot to prevent it from being misused, and the NTSB again asks the automaker to add a more effective method of determining driver engagement during Autopilot operation to prevent more fatal crashes like those that killed Brown and Huang, as well as Jeremy Banner, who in 2019 was killed in very similar circumstances to the crash that killed Brown three years earlier. Chairman Sumwalt was also highly critical of Tesla's failure to respond to the NTSB regarding the investigation into Brown's death. It asks for a response within 90 days; Sumwalt pointed out that it has been almost 900 days since that hearing, with no reply from the California automaker. … [Read more...] about NTSB blasts Tesla, CalTrans, and NHTSA for Autopilot death
If the virus comes into contact with another person but that person isn't susceptible to the disease, then that chain of transmission is snuffed out.If one person infects two, those people together infect four and so on, and eventually, the virus runs out of susceptible people to infect, said Joshua Epstein, a professor of epidemiology at New York University. "What happens typically is that enough people get the bug that there just aren't enough susceptible people to keep the chain going." … [Read more...] about How will the coronavirus outbreak end?
