How many STEM Ph.D.s were lost from the U.S. federal government last year?

My colleagues @mghersher.bsky.social and @policyhound.bsky.social dug into a recent data release to find the answer. A @science.org exclusive.

There have been 3 homicides in Minneapolis this year. Trump’s agents committed two of them: a mom and a nurse who cared for our Veterans.

Stay the hell out of our cities.

This moment in history provides us with incontrovertible evidence that all the conservatives who claim to be extremely devoted to freedom of speech and the right to bear arms, and opposed to the encroachment of tyranny, are completely and totally full of shit.

It's all white supremacy and greed.

Alex Jeffrey Pretti was an ICU nurse at a VA hospital. His life, through his profession, was dedicated to serving his community and our country.

As so many have now seen on video, his final act before he was killed by federal agents was doing everything in his power to protect his community.

A state government is having to file an emergency lawsuit to be able to ensure that the federal government is not actively obstructing justice.

You all know I’m their biggest critic. Credit to @nytimes.com for reporting the truth and not the criminal regime’s lies this time. www.nytimes.com/live/2026/us...
Minneapolis Live Updates: Man Killed by Federal Agents Was Holding a Phone, Not a Gun Videos analyzed by The New York Times appear to contradict federal accounts of the shooting. The man, an I.C.U. nurse, was an American citizen with no criminal record, the city police chief said.

“One officer responded mockingly as he walked away, telling (protesters): ‘Boo hoo.’” apnews.com/article/immi...
After the shooting, an angry crowd gathered and screamed profanities at federal officers, calling them "cowards" and telling them to go home. One officer responded mockingly as he walked away, telling them: "Boo hoo." Agents elsewhere shoved a yelling protester into a car. Protesters dragged garbage dumpsters from alleyways to block the streets, and people who gathered chanted, "ICE out now," referring to Immigrations and Customs Enforcement. "They're killing my neighbors!" said Minneapolis resident Josh Koskie.

ICE agents will continue to execute our citizens in the streets for as long as they believe they can get away it. There will be more executions like this. What are our leaders doing to prevent it?

Walz: "We sill investigate this. We will not be stonewalled ... this will end when enough American say this will end. Do I have any confidence that Donald Trump will do the right thing? No ... quit referring to these people as law enforcement. They are not law enforcement."

New — I wrote about ChongLy Scott Thao, the elderly Hmong American wrongly arrested and forced out of his home by ICE in his underwear during the punishing Minnesota winter, what witnesses saw, and DHS's racist claim that he fit the description of another Asian man they were looking for.

My story:
Behind the disturbing image of ICE snatching a half-naked, elderly Hmong American from his home
DHS has claimed without evidence that they were looking for someone else when they took ChongLy Scott Thao.

They’re investigating everyone except the murderer.

The DOJ is not investigating ICE agent Jonathan Ross for the fatal shooting of Renee Good, a top official said Sunday.

The top DOJ official confirmed that an investigation is underway into Gov. Tim Walz and Minneapolis Mayor Jacob Frey.
Justice Department says it has no plans to investigate ICE agent who killed Renee Good and confirms Walz, Frey probe
Frey and the governor’s office both said Sunday that the DOJ has not contacted them about the investigation.

Mubashir and his family came to the United States as refugees from Ethiopia when he was a child, and they all became naturalized citizens in 2019.

Despite being a U.S. citizen, Mubashir was targeted by ICE, assaulted, and detained. Listen to his story:

Let’s call this what it is: a disgusting abuse of power and a farce.

As his agents terrorize Minnesotans, as prices rise, as he fails to deliver for Americans, he is also weaponizing the DOJ against his perceived enemies.

This is not a banana republic and justice will prevail.

Reminder if you find yourself somehow running out of space on your multi-TB laptop to check your ~/.cache size. I got 150 GB of disk back today by doing some trivial cleanup.

```
du -ch ~/.cache | tail -1 | cut -f1

Caches are wonderful things and having large caches on large disks is great!

Excited to receive my copy of the second edition of Maxwell Dashwood and Christopher Hendon’s Water for Coffee! This book has been long awaited and I’m looking forward to learning much more about water chemistry beyond the little bits I have so far from making my own coffee water at home.

The US Department of Agriculture suspends all federal funding to Minnesota, effective immediately.
January 9, 2026 THE HONORABLE TIM WALZ Governor of Minesota 130 State Capitol 75 Rev Dr. Martin Luther King Jr. Bivd. St. Paul, MN 55155 THE HONORABLE JACOB FREY Mayor of the City of Minneapolis City Hail 350S. Fifth St., Room 330 Minneapolis, MN 55415 Dear Governor Walz and Mayor Frey, It is my responsibility as Secretary of Agriculture to ensure sound stewardship of taxpayer dollars by climinating fraud, waste and abuse in all programs funded by the U.S. Department of Agriculture (USDA). The widespread and systemic fraud associated with federal benefit programs in the State of Minnesota and the City of Minneapolis demonstrate an inability to handle federal resources without additional oversight and accountability measures in place. During your tenures as Governor of Minnesota and Mayor of Minneapolis, numerous non-profits and businesses have defrauded the federal government in what a federal prosecutor in Minnesota called "a staggering, industrial-scale fraud".! Most notably, a Minneapolis-based nonprofit— Feeding Our Future defrauded U.S. taxpayers of nearly $250 million in federal funds given to them by the Minnesota Department of Education.? This fraud scheme involved USDA funding provided to the State of Minnesota to feed hungry children under the Child and Adult Care Food Program (CACFP) and the Summer Food Service Program (SFSP). As of late November, 78 defendants had been charged in what the Department of Justice characterized as the largest COVID-19 fraud scheme in the country? Other recent examples of'alleged fraud in Minnesota include exploitation of the Small Business Administration Paycheck Protection Program", a scheme to defraud the Housing Stabilization 1-Whut te know about Minnesoca' "industrial-scale fraad" scandal, as more charges are fled and Trump weighs in, "CES Nows (Dic. 19, 3025) available at ht:/www.cbsnews.com/news/atas-do-know-alonesota-frawf-candal were-changes-fled- tump-water. /Federal Jury Finds Feeding Our Future Masternind and Co-D… Services Program", and alleged fraud in daycare centers*, Your Administrations have refused additional accountability and oversight, claiming that criticism of rampant fraud and abuse is "racist." While the full extent of fraud in Minnesota is not yet known, it is clear that, under your leadership- or lack thereof fraudsters can take advantage of federal funds and the American taxpayer with impunity. This necessitates federal action to protect taxpayer dollars until adequate safeguards can be established. Despite a staggering, wide-reaching fraud scandal, your Administrations refuse to provide basic information or take common sense mcasures to stop fraud. In fact, rather than conlin your SNAP rolls are accurate to prevent continuing fraud, you asked the courts to block USDA's directive to recertify the State's SNAP recipients. Recent news reports also emerged that the Minnesota Department of Human Services repeatedly reported incorrect information about SNAP to the federal government.? The Trump administration refuses to allow such fraud to continuc. Therefore, because of your failed Icadership and abysmal financial management oversight, 1 am notifying you that, effective immediately, I am suspending payments on all active awards and any future awards from USDA to the State of Minnesota and the City of Minneapolis, currently totaling over $129.18 million. Within 30 days, you shall provide USDA with payment justifications for all federal dollar expenditures from January 20, 2025, to the present. Going forward, all transactions on awards to the State of Minnesota or the City of Minneapolis will require such payment justification. If those payment justifications are not received, awards will remain suspended. While your Administrations have turned a blind eye to documented fraud, the Trump Administration has made clear that fraud, waste, and abuse are unacceptable. The American people deserve to know that their taxpayer dollars are helping those in need-not criminals. …
