Spiders Use Earth’s Electric Field to Fly

Spider’s only “balloon” in light winds, which are not enough to account for their lofty flights.  Now, researchers at the University of Bristol, have shown that spiders can sense the charge in the air, and use it to determine when to launch.

Scientific publishing is a rip-off. It’s time to change.

Illustration: Eva Bee

The current scientific research publishing model was started  by Robert Maxwell. He realised that, because scientists need to be informed about all significant developments in their field, every journal that publishes academic papers can establish a monopoly and charge outrageous fees for the transmission of knowledge. He called his discovery “a perpetual financing machine”. He also realised that he could capture other people’s labour and resources for nothing. Governments funded the research published by his company, while scientists wrote the articles, reviewed them and edited the journals for free.   Now new plans hope to change all that making all science information free.  https://sci-hub.tw/
