Startups Are Racing to Make Water Out of Thin Air Materials that are bigger on the inside than the outside provide a futuristic solution to supply water to an increasingly arid planet.

One of today's winners of the Nobel Prize in Chemistry is UC Berkeley professor Omar Yaghi. Last year I wrote about Yaghi and Atoco, the startup he founded to commercialize his scientific breakthrough with a device that extracts water from air using just sunlight.

Trump Labor Department Says His Immigration Raids Are Causing a Food Crisis In a filing in the Federal Register, the Labor Department argues there are “immediate dangers to the American food supply” due to a lack of migrant agricultural workers.

Missing wind from Milky Way’s giant black hole finally found Astronomers may have glimpsed a long-predicted wind of gas blowing out from Sagittarius A*

For essentially every supermassive black hole that astronomers have studied, they've spotted powerful winds blowing out from the event horizon to shape the surrounding galaxy. Except for the one in the Milky Way. 🌟 ⚫ 🌬️

The case may now be closed. @science.org tinyurl.com/5y99b7az #space #astronomy

This discovery traces back to the spring of 2018, when I was a postdoc in nikogeldner.bsky.social 's lab. After shifting Arabidopsis seedlings from solid to liquid culture, I observed that the root commensal bacterium CHA0 rapidly colonized Casparian strip–defective mutants.

This 1771 painting by Joseph Wright of Derby is titled:

"The Alchymist, In Search of the Philosopher’s Stone, Discovers Phosphorus & prays for the successful Conclusion of his operation, as was the custom of the Ancient Chymical Astrologers."

Let's talk about how phosphorus was discovered.

Wow that’s like a plants level of chromosomal absurdity

A good day to remember John Gurdon’s school report from his biology master at Eton

If you were determined to devastate places like the Arkansas Delta, where I grew up, you'd be hard pressed to come up with a more destructive set of policies. It's soybeans and rice as far as the eye can see. It's not an incidental fraction of the local economy, it is the entire foundation of it.

I just emailed my "Silence" essay to the Presidents/Chancellors and Provosts of the 9 Compact universities as well as those from the 4 orgs with which I have been formally affiliated.

A disgruntled Green Frog sits on the edge of a container pond

Frog’s take on the current state of things

The last three government shutdowns have happened while Donald Trump was President.

This shutdown, like all recent shutdowns, is a REPUBLICAN SHUTDOWN.

Enough with the chaos. Time for Republican leadership to work with Democrats to reopen government and save your health care.
