Fascinating story by @hannah_hagemann: Scientists are 'harvesting' fog for water. Here's what it could mean for California "Fog — a part of daily life for millions of Californians — is fundamentally fickle." Photo by @YOSHIFOTO sfchronicle.com/weather/arti…

Scientists are turning fog into water. Here’s what it could mean for California

California scientists are harvesting fog and see its potential to augment water supplies. The amounts are modest, but fog water could be impactful as climate change accelerates.

Looking for a change of pace when folks gather on Thanksgiving and don't want to talk politics? Try this eye-popping survey of what AI gets wrong about SF, from tri-towered Golden Gate Bridges to foliage-shrouded towers. Aka my final @sfchronicle byline: sfchronicle.com/projects/202…

How AI depicts San Francisco — and what it gets wrong

We asked four different generative AI models to depict today’s San Francisco, its residents and how the city would look in 2074.

Still have those eclipse glasses handy? Quick, look at the Sun — there is a sunspot group large enough to see without a telescope (using a proper solar viewing method, of course)! That's active region 13848, which has produced two M-class flares in the past week. 🤩
A detailed image of the Sun's surface, featuring several sunspots. The Sun appears as a large yellow disk against a black background, with dark patches indicating sunspots scattered across its surface.

What's the best event in San Francisco? We held a ranked-choice poll to find out, but also used the results to explain how ranked-choice voting works, including whether voters can "game" the system sfchronicle.com/projects/202…

We held a poll on the best S.F. event. It shows if ranked-choice voting can be gamed

Ranked-choice voting is used in SF to elect some local officials. To demystify RCV, the Chronicle ran a ranked-choice poll to vote on people's favorite event.

How many cars vs. pedestrians use SF's Great Highway? I was curious about Prop K's potential impact, so I went out to the Great Highway and counted every car & pedestrian I saw over the course of an hour Here's what I found @sfchronicle sfchronicle.com/projects/202…

How many cars and people use S.F.’s Great Highway? The numbers surprised us

One of the more contentious items on the November ballot is Proposition K, the choice to close SF’s Upper Great Highway to cars and turn the road into a park.
