US passes 5 million coronavirus cases

Published

As school districts across the country struggle to figure out how — or if– to safely reopen schools to teachers and students, the number of coronavirus cases in the US passed 5 million on Sunday, according to the Coronavirus Research Center at Johns Hopkins University. And according to a Washington Post analysis, the US hit the 5 million mark just 17 days after passing 4 million cases.

The US leads the world in the number of coronavirus cases, accounting for nearly a quarter of the 19.7 million cases worldwide. As of Sunday, Brazil was second with just over 3 million cases, followed by India at 2.1 million cases. And the US is at the top of another grim coronavirus list, according to Johns Hopkins, with more than 162,000 deaths.

While researchers at the University of Washington believe case counts may have peaked in many of the hardest-hit states, they’re now projecting that the number of coronavirus-related deaths in the US could hit 300,000 by December, NPR reported. New York, which was hard hit in the early days of the pandemic, has the most coronavirus deaths among US states, at more than 32,000, followed by New Jersey at almost 16,000 and California at more than 10,000 deaths, the Johns Hopkins data show.

On Saturday, President Trump signed four executive orders aimed at providing coronavirus relief, but it’s not clear whether they comply with the law. The US unemployment rate is currently at 10 percent.

The US reached 5 million cases the same day New Zealand announced it had gone 100 days with no new cases of domestic transmission of the coronavirus.

Too bright to breed

Night light from coastal cities overpowers natural signals for coral spawning from neighboring reefs.

Most coral species reproduce through broadcast spawning. For such a strategy to be successful, coordination has had to evolve such that gametes across clones are released simultaneously. Over millennia, lunar cycles have facilitated this coordination, but the recent development of bright artificial light has led to an overpowering of these natural signals. Ayalon et al. tested for the direct impact of different kinds of artificial light on different species of corals. The authors found that multiple lighting types, including cold and warm light-emitting diode (LED) lamps, led to loss of synchrony and spawning failure. Further, coastal maps of artificial lighting globally suggest that it threatens to interfere with coral reproduction worldwide and that the deployment of LED lights, the blue light of which penetrates deeper into the water column, is likely to make the situation even worse.

SpaceX launches Starlink app and provides pricing and service info to early beta testers

Published

on

SpaceX has debuted an official app for its Starlink satellite broadband internet service, for both iOS and Android devices. The Starlink app allows users to manage their connection – but to take part you’ll have to be part of the official beta program, and the initial public rollout of that is only just about to begin, according to emails SpaceX sent to potential beta testers this week.

The Starlink app provides guidance on how to install the Starlink receiver dish, as well as connection status (including signal quality), a device overview for seeing what’s connected to your network, and a speed test tool. It’s similar to other mobile apps for managing home wifi connections and routers. Meanwhile, the emails to potential testers that CNBC obtained detail what users can expect in terms of pricing, speeds and latency.

The initial Starlink public beta test is called the “Better than Nothing Beta Program,” SpaceX confirms in their app description, and will be rolled out across the U.S. and Canada before the end of the year – which matches up with earlier stated timelines. As per the name, SpaceX is hoping to set expectations for early customers, with speeds users can expect ranging from between 50Mb/s to 150Mb/s, and latency of 20ms to 40ms according to the customer emails, with some periods including no connectivity at all. Even with expectations set low, if those values prove accurate, it should be a big improvement for users in some hard-to-reach areas where service is currently costly, unreliable and operating at roughly dial-up equivalent speeds.

In terms of pricing, SpaceX says in the emails that the cost for participants in this beta program will be $99 per moth, plus a one-time cost of $499 initially to pay for the hardware, which includes the mounting kit and receiver dish, as well as a router with wifi networking capabilities.

The goal eventually is offer reliably, low-latency broadband that provides consistent connection by handing off connectivity between a large constellation of small satellites circling the globe in low Earth orbit. Already, SpaceX has nearly 1,000 of those launched, but it hopes to launch many thousands more before it reaches global coverage and offers general availability of its services.

SpaceX has already announced some initial commercial partnerships and pilot programs for Starlink, too, including a team-up with Microsoft to connect that company’s mobile Azure data centers, and a project with an East Texas school board to connect the local community.
