Mamdani has only been Mayor for a day & criminals are already fleeing New York

Made a bucket full of batter to bake Dutch 'Oliebollen', which we enjoyed in style with traditional Dutch weather. Happy New Year, best wishes for 2026!

First big family meal prepared on this battery powered induction stove...

I am quoted in this piece on our efforts of a cross-disciplinary group of faculty to teach Climate Change Literacy to all students at @ucdavis.bsky.social

Hadn’t seen this one before. The good news is that we have many smart solutions to address the surrendering of cities to cars that don’t involve tire spikes. But they DO involve actual political will, strengthened by public understanding of the serious need to act. Via @xkcd.com

It’s the “season of love and giving”…but this year, doesn’t it seem more like a “season of fear and taking”? Like many of you, I’ve been saddened by the human impact of draconian government budget cuts and how angry many housed Americans are at unhoused Americans. 🧵 1 of 9

Davis, CA, bike lane in front of Willett Elementary - one of the oldest bike lanes in the US. Par for course at Davis schools.

Last year Davis made the Elite Eight after entering as an unseeded contestant - talk about a Cinderella story ;-) Glad to see we're on track for a ranked seed this year.

Outside of my favorite friendly neighborhood brewery last night in Davis. Only one of these vehicles that likely was driven home after the consumption of alcohol weighs in excess of 6,000 pounds and has poor visibility because the hood is so tall...

It’s been two weeks since ICE took Yuanxin Zheng from his father. He is six years old. He’s still not home. This has to end.

Lol, Zillow tried to rate the climate risks facing individual properties. The real estate industry *hated* it, precisely because it worked -- it made selling risky properties more difficult. So they rebelled & Zillow caved. Don't look up!

Thanksgiving groceries plus awesome shopping assistant. Happy Thanksgiving!

The hard truth: If this Council fails to pass Universal Daylighting or passes a watered down version, kids will die, and it will be entirely Adrienne Adams' fault.

Insane but true fact: making US roads as safe as Canadian, Australian, or European roads would save more lives than eliminating murder from the US.

I will never forget having to edit Jamal’s final, posthumous piece for the Washington Post, after he was murdered. He was calling for free expression in the Arab world. You can read it here : www.washingtonpost.com/opinions/glo...

A leading federal judge quits in protest of Trump's corruption-- & to fight it Wow www.theatlantic.com/ideas/2025/1...

My 4th grader at a packed City Council last night asked for a safe bike/ped overpass over a busy road to connect a new development instead of needing to wait up to 2.5 minutes at a light as planned. He then asked everyone to wait with him for the duration of his comment to share how long that is.

“Recent studies show that between 80% — 89% of the world’s population wants to see climate action. Many would even contribute 1% of their income to make that happen, even tho people vastly underestimate their peers’ desire for change. Members of this “silent majority” come from all walks of life…”’

Some great & important news out of the Netherlands: “Dutch Voters Deliver Major Setback to Far-Right Party of Geert Wilders [who controlled the last coalition government before it collapsed]. A center-left party was poised to become the country’s largest political party, according to exit polls.”

Dropping off kid to a play date - it may rain so whipped out the rain cover for the first time this season.

One of the many things @ninalakhani.bsky.social does so well is show the very real, very now cost of climate change at the most human level. This story is devastatingly good: www.theguardian.com/environment/...

Biked a #bikebus to the Davis Varsity Theater to watch a free movie today with 120 Davis elementary school kids from 3 different schools). Such a blast - thankful to mayor @bapuvaitla.bsky.social for biking with us to encouraging kids to bike more and to Bike Davis for sponsoring. So much fun!!!

Posting for no particular reason at all.

Newsom just signed an excellent law that will help fund the widespread transition from natural gas boilers to industrial heat pumps. Now sign SB79, Gavin.

A Newly Recognized Pathway Could Protect Diabetics from Hypoglycemia @huisinglab.bsky.social www.ucdavis.edu/news/newly-r...

New work from @huisinglab.bsky.social at UC Davis shows how delta cells in pancreatic islets dampen insulin production and prevent a sudden drop in blood sugar. It could lead to new ways to help people with diabetes. www.ucdavis.edu/news/newly-r...

🔥💯 Jon Stewart's prophecy from 2022: "When a democracy is under threat: comedians are the ones who get sent away first. Authoritarians are the threat to comedy, to art, to music, to thought, to progress. It ain't the pronoun police, it's the Secret Police. It always has been & it always will be."

Very proud to see the main thesis work of the intrepid Dr. Mohammad Pourhosseinzadeh come out in @pnas.org today! In this paper, Mohammad assesses how crosstalk between insulin-secreting beta and somatostatin-secreting delta cells in the islet actually happens, in near real-time. A quick thread 1/10

Yeah man they ain’t coming back. This is going to be one of the biggest foreign policy blunders of my lifetime, and it’s entirely possible that some guy at ICE ordered it not having any clue what he was doing. This is why we used to leave foreign affairs to sensitive nerds.

Biking to the pasta Feed of the Davis high school XC team to help feed some of the 150 athletes before their race. Great group of kids and fun event, despite slight delay as one of our bike's chain rattled off due to the terrible condition of the pavement of the once great Davis bike trail network.

This matters a lot more than his tweets.

If your yard stick for success of a society is 'robotaxis' you have completely lost the plot. Not efficient affordable public transit, not universal health care, or a functioning democracy for that matter, no 'robotaxis'. JFC...

Canada’s out-of-control wildfire crisis in six charts. Important new analysis from @nationalobserver.com's @bsaxifrage.bsky.social 👇 www.nationalobserver.com/2025/09/03/a...

We used to have a colony of Mexican free-tailed bats in our attic, until we excluded them years ago. A handful keep coming back to feed around the house every summer night. This is from just a few weeks - imagine how many insects they devour to produce this much bat shit!

Of mice and men... 🧪 Work by postdoc Laura Reininger in collaboration with @huisinglab.bsky.social and Michelle Kimple. Differences in the regulation of insulin secretion by FFAR4 between mouse and human islets. @crchum.bsky.social @umontreal-en.bsky.social www.biorxiv.org/content/10.1...

Spouse picked up groceries for the week on the way back from dropping kid #2 off for a play date. #cargobike

As we are apparently at war with wind, a picture from a few years back of an 86-turbine near-shore wind farm in the Netherlands, 3 miles from nearest shore (=barely visible), generating enough cheap, renewable energy to power half a million households (out of 8.4 M total).

Scoop: The Trump administration is now pushing for national mandatory land use restrictions on all wind projects — including those on private land — by claiming they present a risk to critical communications infrastructure.

The anti-science Trumpers may be planning to destroy two working satellites that provide vital measurements about carbon dioxide & climate (and data that forecasts crop yield, drought conditions, & more). They cost $750 million to make but only $15 million/yr to operate. www.npr.org/2025/08/04/n...

Important details from this story: 1) Yet another news-break by student journalists (this time @theharvardcrimson.bsky.social) www.thecrimson.com/article/2025... 2) Harvard saying "see you in court," not "let's make a deal." 3) Per Garber, WH/MAGA leaked news of a "deal." NYT then ran with it.

Why can't CA do as NY just did and ban fossil gas in new buildings. I electrified in a retrofit and my energy bills went down, plus it is more comfortable, pleasant and healthy to breathe indoor. We can and should build quickly AND energy efficiently. We should be ditching FFs at every opportunity.

A hugely important verdict. The victims were pedestrians, so Tesla can't argue they knew/accepted Autopilot's risks. People walking, biking, and inside other cars didn't consent to be Elon Musk's guinea pigs.

If you are a scientist who agrees that this abject denial of settled science by limiting the EPA's ability to regulate GHGs is terrifyingly shortsighted, economically absurd and NOT in the best interest of the American public, consider signing in support of climate science and public health.

On July 23, the International Court of Justice issued a historic advisory opinion on states’ legal duties to address climate change. Though not binding, it carries global weight and could influence law, policy, and climate justice efforts for years to come. Here’s why it matters:

Grabbed a beer after work with colleagues last night. Both of these vehicles transported one person to - and from - my neighborhood brewery.

Overflow crowd at UC Davis listened to Congressman Thompson (CA-4) who pledged his unwaivering support for federally funded science. Heard from so many who are deeply impacted by federal cuts to scientific funding. Grateful to congressman Thompson attending and representing @ucdavis.bsky.social
