A record deadly week for US avalanches in early February
2021 has brought a deadly avalanche season. “We’re only halfway through the season and we’re 3/4 of the way to the number of fatalities we’d see in a typical year. The dangerous, record-breaking year keeps avalanche forecasters up at night,” one expert said. Source: https://earthsky.org/human-world/avalanches-2021-united-states-how-to-survive…
Grizzlies Are Coming Back. But Can We Make Room For Them?
As grizzly bears expand their range in Montana, Idaho, and Wyoming into places where they haven’t been seen in a century or more, they’re increasingly encountering humans. From a report: Things intensified last summer as trails and campgrounds across the region flooded with inexperienced tourists seeking refuge in the outdoors during the coronavirus pandemic. Grizzly attacks spiked. Bear managers were inundated…

US Used Patriot Act To Gather Logs of Website Visitors
An anonymous reader quotes a report from The New York Times: The government has interpreted a high-profile provision of the Patriot Act as empowering F.B.I. national security investigators to collect logs showing who has visited particular web pages, documents show. But the government stops short of using that law to collect the keywords people submit to internet search engines because it…
Clovis made stone tools for only around 300 years

Starlink Beta Testers Are Impressed With Its Speed
One beta tester of SpaceX’s new Starlink satellite internet service is a Reddit user named “wandering-coder”. This week they shared their experience online, testing the equpiment in a national forest which gets no cell service from any carrier — and using it to upload this report: Works beautifully. I did a realtime video call and some tests. My power supply is…

Some Cities are Combining Basic Incomes with Local Currenices
Bloomberg looks at some interesting local currency programs that have been implemented around the world. And in at least one case money “is literally being made from trees” — the wooden dollars being printed in a small city in the northwest U.S. and distributed to the needy in monthly stipends. “We preach localism and investing in our local community,” says mayor…
Tiny bubbles make a quantum leap
July 13, 2020—Researchers at Columbia Engineering and Montana State University report today that they have found that placing sufficient strain in a 2-D material—tungsten diselenide (WSe2)—creates localized states that can yield single-photon emitters. Using sophisticated optical microscopy techniques developed at Columbia over the past three years, the team was able to directly image these states for the first time, revealing that…
