The real insanity isn’t how much oil prices have spiked, it’s that we’re still burning oil for energy.

Can anyone tell me what the bike industry and/or People For Bikes are doing about the way e-bikes are being blamed for havoc caused by people riding electric motorcycles?!!?

WAY MORE THAN HALF THE STORIES ABOUT DEATHS CAUSED BY E-BIKES DO NOT INVOLVE E-BIKES. THIS IS KIND OF IMPORTANT.

This is a shock. Colleen Hanabusa has held and competed for so many public offices in Hawaiʻi in the short time that I've been there (US House of Representatives, US Senate, Hawaiʻi State Senate, Governor of Hawaiʻi, Mayor of Honolulu, Board of Honolulu Authority for Rapid Transportation). RIP.

A senior scientist spammed a mailing list of most of the scientists in my field with his latest paper in a predatory publisher's journal with nonexistent peer review.

I replied to all with: "We’re going to rescind your PhD for publishing with MDPI."

He was not pleased. 😅
