NSF GRFP is out 2.5 months late w/key changes 1. 2nd year graduate students not eligible. 2. "alignment with Administration priorities" 3. Unlike prior years, they DO NOT specify the expected number of awards... that is a BIG problem. a brief 🧵 w/receipts www.nsf.gov/funding/oppo...

Water pollution doesn't necessarily stay in the water, and downwind communities suffer. Proud to have been a part of this study led by Ben Rico and the Prather team at UCSD, and hoping for some effective action to clean things up soon. @kprather.bsky.social www.science.org/doi/10.1126/...

Horrific & stupid. Polio will come back to Florida. By the way, everyone should just follow WHO guidance on vaccines. They are there (despite recent funding losses as America leaves the chat) to guide everyone, including folks in fragile states or in other places that lack competent leadership.

This is the sort of work this administration is halting with their ridiculous, backward policies. Public health scientists solve important problems and help people.

These monsters are undoing decades of progress. We will all be sicker. More people will die. Needless suffering brought on my willful ignorance, grievance, spite, & cruelty. I have no words to describe how distressing this all is. There is just no point. Never let the pigeon drive the bus.

Just assume flood water has poo in it, because it universally does, though human versus animal & the amounts differ a lot. But any flood water carries exposure risks. www.nytimes.com/2025/08/18/w...

New Jersey scientists are testing mosquitoes after a resident may have contracted malaria locally, which health officials said would be the first known instance in decades of someone being exposed while in the state.

Today on the sanitation beat: near constant shitting Birds have to top the list of daily defecation by body mass, as observers of Canada geese & chickens will attest. But some clearly top the league tables. "Streaked shearwaters ... [shed] about 5 percent of their body mass every hour."

Today on the sanitation beat: sanitation as public art: "You don’t want to scream ‘sewer pipe’ at people" Actually yes, yes I do! www.theguardian.com/artanddesign...

I am getting the sense that the people running the government oppose everything I have ever worked for Or, more generously, they fundamentally misunderstand & therefore do not appreciate the importance of environmental quality & public health, & so don’t care I don’t understand this

Every rebuttal letter

A looming global water crisis may be under appreciated as climate change takes hold. Today I report on a new study that finds the planet is quickly drying, with mega-regions of water loss now stretching across continents. www.propublica.org/article/wate...

Professor achievement unlocked

Why do we put so much emphasis on chemistry in relationships? Seems to me that having good physics or biology with someone is just as important. To say nothing of psychology.

Deeply grateful we don't have combined sewers here in Chapel Hill - the 9+ inches of rain we got could have resulted in a scary preponderance of ... shIT.

Words cannot describe how excited I am to share the findings from the second half of my postdoc in @aaronwhiteley.bsky.social's lab where we discover that bacteria use functional amyloids to defend themselves from predatory bacteria. rdcu.be/euu5Y. See thread for details on this epic adventure 1/.

no. men must never acquire the devastating power of the Novel. in fact we should preemptively invade their country to shut down their efforts to develop fiction

So cool, a novel archaeon with a super small genome and no metabolic genes! "An unprecedented level of metabolic dependence on a host, a condition that challenges the functional distinctions between minimal cellular life and viruses." www.biorxiv.org/content/10.1...

I’m observing a lot of people in my world who seem to just be running out of steam.

I have been arguing that Jaws is such an important political & philosophical film for so long. I feel vindicated! I can’t wait until the cognoscenti begin to recognize the other: Ghostbusters II But of course these two, as well as Deliverance, are just retellings of Moby Dick Plus ca change

Millions will get sick & die because our government has abandoned its leadership role in global health. I fear the damage will not be easily undone. Exhibit A

I keep telling cautionary tales but no one is listening

This homage to the transformative power of great teachers really struck a chord. I could have written this essay: I too was a traumatized kid. Great teachers reached me & changed my life. I'm now married to a great teacher & I couldn't be prouder of her & the work she does. For far too little $.

My mom had polio, was disabled her entire life, it severely impacted my entire family & me personally, & she died way too early. She contracted it in infancy shortly before the Salk vaccine roll-out. These attacks on vaccines are a public health nightmare. Many people are going to get sick & die.

It is an age of uncautious pessimism One fears for the republic

Old well on my new home place. About 30’ deep, hand dug & lined with rock.

The coolest thing about talking with my kids about the birds & the bees is the part about how the bees are a matriarchy of warriors that have enslaved males for reproductive purposes & also removed their stingers & they die directly after mating & their useless little bodies are discarded forthwith
