The climate warning signs are transforming into sirens.

From the abstract: "Here, we used a standardized protocol to measure total insect biomass using Malaise traps, deployed over 27 years in 63 nature protection areas in Germany (96 unique location-year combinations) to infer on the status and trend of local entomofauna. Our analysis estimates a seasonal decline of 76%, and mid-summer decline of 82% in flying insect biomass over the 27 years of study. We show that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline. This yet unrecognized loss of insect biomass must be taken into account in evaluating declines in abundance of species depending on insects as a food source, and ecosystem functioning in the European landscape."

This starts in about 10 minutes. It will first be available on Twitch here: https://go.twitch.tv/megabotsinc

Any old MechWarrior pilots out there thinking this is about time?
MegaBots vs Suidobashi Robot Duel to Stream Live on @Twitch Oct 17th 7PM PT | @MegaBots
https://blog.adafruit.com/2017/10/16/megabots-vs-suidobashi-robot-duel-to-stream-live-on-twitch-oct-17th-7pm-pt/

Tune tomorrow 10/17/2017 at 7PM PT/10PM ET to watch an epic robot duel between America’s MegaBots and Japan’s Suidobashi!

Two years ago, U.S. robotics company MegaBots challenged its Japanese rival, Suidobashi Heavy Industries, to a duel between their giant robots. Suidobashi had accepted but added a condition of its own: melee combat must be a part of the fight.

To make sure its robot was up to the task for hand-to-hand combat, MegaBots started a Kickstarter to upgrade its Mk.II robot, which was built mostly for long-range paintball combat. It raised about $554,600 in crowdfunding from nearly 8,000 backers.

In August the company officially introduced the robot that would take part in the fight.

Stone tools and mastodon bones occur in an undisturbed geological context at the Page-Ladson site, Florida. Seventy-one radiocarbon ages show that ~14,550 calendar years ago (cal yr B.P.), people butchered or scavenged a mastodon next to a pond in a bedrock sinkhole within the Aucilla River. This occupation surface was buried by ~4 m of sediment during the late Pleistocene marine transgression, which also left the site submerged. Sporormiella and other proxy evidence from the sediments indicate that hunter-gatherers along the Gulf Coastal Plain coexisted with and utilized megafauna for ~2000 years before these animals became extinct at ~12,600 cal yr B.P. Page-Ladson expands our understanding of the earliest colonizers of the Americas and human-megafauna interaction before extinction.

“It’s a very solid paper experimentally,” says evolutionary genomicist B. Franz Lang of the University of Montreal in Canada. “If you’d like me to bet, I’d give them 90% probability that they are correct.” To strengthen the case, he says, researchers need to perform a detailed microscopic analysis to confirm the absence of the organelles. Evolutionary biochemist Mark van der Giezen of the University of Exeter in the United Kingdom also wants to see further evidence that Monocercomonoides doesn’t harbor rudimentary mitochondria. Nonetheless, he says, the study expands our view of eukaryotes’ capabilities. “It shows that eukaryotic life is more flexible than what the textbooks say.”

What spider is this?

It was caught indoors near Houston, Texas, USA.

New tabletop detector “sees” single electrons

MIT physicists have developed a new tabletop particle detector that is able to identify single electrons in a radioactive gas.

As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted by the electrons, which can be used to map the electrons’ precise activity over several milliseconds.
A new detector developed by researchers from the MIT Department of Physics “sees” single electrons and could help measure neutrino mass: http://mitne.ws/1EnRgLa
