Time's rolled on: my own blog just turned 25, and it's now roughly 40 years since I first sat down at a computer.

alternative_right shares a report from ScienceAlert: If you consumed a wild mushroom and suddenly started seeing tiny people around you, you might reasonably assume it contained a familiar psychedelic. But that does not appear to be the case with Lanmaoa asiatica, known locally as jian shou qing, a mushroom species sold in markets in Yunnan, southwestern China.

An anonymous reader quotes a report from the New York Times: Mr. Zuckerberg, the chief executive of Meta, recently dispatched a small team at his company to create a smartphone app similar to Polymarket and Kalshi, two employees with knowledge of the matter said. Users would not wager money, and the app would probably rely on a video game-like points system instead, one person said, though the company had not ruled out the eventual use of real money betting. The app is internally referred to as…

Canada has unveiled a national strategy to build up to 10 new nuclear reactors over the next 15 years as it seeks to double electricity-grid capacity by 2050. Energy Minister Tim Hodgson called it a plan for a "new civilian nuclear renaissance." "If our goal is to double our grid and build a low-carbon economy in less than 25 years, there is no credible plan to do that without nuclear energy and the clean, reliable baseload power it provides," Hodgson said. "There is no credible plan for Canada…
