This is wild!

Seven-day-ahead weather forecasts in high-income countries are more accurate than one-day-ahead weather forecasts in low-income countries.

As the number on the list approached the total number likely to be recommended for funding (typically ~75%), each application was presented and discussed. These discussions tended to be rich and could be spirited as each program officer had opinions and also had competing favorites.

The “malleability of students to what they study” seems exactly right to me but it’s so good to have empirical confirmation.

The riskiness of STEM focus feels like it doesn’t *need* to be true yet probably *is* true in most settings, whereas the political consequences probably vary across settings?
We examine the impacts of assignment to STEM vs. humanities-focused curricula in Romania’s high school system. We apply a regression discontinuity design to administrative and survey data to estimate effects on educational pathways, desired careers, and non-cognitive outcomes. An overarching theme of our findings is the malleability of students to what they study. Assignment to STEM increases STEM college enrollment and technology or engineering career intentions by 25 pp. Exploring mechanisms, we find that STEM assignment changes students’ self-perceived academic abilities and their preferences over academic subjects and job tasks. STEM assignment is risky for low-achieving students, reducing their chances of passing a high school exit exam and enrolling in college. A final finding is that STEM makes boys more conservative, while shifting some of girls' views to the left. Our results identify a strategy for promoting STEM higher education and careers, but also highlight potential tradeoffs.

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

My hot take is that over the next 10 years, we're going to see more emphasis on and investment in the humanities at Ivy League and other fancy schools just as state schools and small privates continue to decimate and even eliminate the humanities.

"While other universities report that the humanities are shrinking, at Berkeley, the opposite is true. The music major is the fastest-growing major on campus. We are finding bigger classrooms because film is exploding. English is back to the numbers we saw 15 years ago. We are hiring" bit.ly/4ohKuOe

Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

This week, I withdrew from a speaking engagement at a public university because they sent me a list of prohibited “words & concepts.” I will not humor this censorship. It does a disservice to the stories I’m discussing & the audience, who deserve unfettered access to information & conversation.
“Prohibited words and concepts: Equity, diversity, & inclusion; anti-racism; Bias; Critical race theory; implicit bias; oppression; intersectionality; prohibited discriminatory practices; racial privilege; promoting stereotypes based on personal identity characteristics.”

CDC has overhauled its website to assert that “the claim ‘vaccines do not cause autism’ is not an evidence-based claim”
Autism and Vaccines QUESTIONS AND CONCERNS PAGE 2 OF 9 | ALL PAGES J For Everyone NOV. 19, 2025 KEY POINTS • The claim "vaccines do not cause autism" is not an evidence-based claim because studies have not ruled out the possibility that infant vaccines cause autism. • Studies supporting a link have been ignored by health authorities. HHS Research on Plausible Biologic Mechanisms between Vaccines and Autism HHS will evaluate plausible biologic mechanisms between early childhood vaccinations and autism. Mechanisms for further investigation include the impacts of aluminum adjuvants, risks for certain children with mitochondrial disorders, harms of neuroinflammation, and more. * The header "Vaccines do not cause autism" has not been removed due to an agreement with the chair of the U.S. Senate Health, Education, Labor, and Pensions Committee that it would remain on the CDC website.

Previously, the UN used each country’s own definitions of which areas were urban. That approach tells us that only 58% of the global population was urban in 2025. In contrast, the new 81% statistic is based on a universal definition of urban areas as relatively dense settlements of 5000+ people.

WE JUST KEEP WINNING. (UC President's Postdoctoral Fellowship Program RESTORED!!!!)
On official UC letterhead: UNIVERSITY OF CALIFORNIA James B. Milliken President Office of the President 1111 Franklin Street Oakland, CA 94607 universityofcalifornia.edu CAMPUSES Berkeley Davis Irvine UCLA Merced Riverside San Diego San Francisco Santa Barbara Santa Cruz MEDICAL CENTERS Davis Irvine UCLA San Diego San Francisco NATIONAL LABORATORIES Lawrence Berkeley Lawrence Livermore Los Alamos DIVISION OF AGRICULTURE AND NATURAL RESOURCES November 18, 2025 Dear Chancellors: I'm writing with regard to the President's Postdoctoral Fellowship Program (PPFP) and the program's associated faculty hiring incentive. As you know, for more than 40 years, PPFP has provided postdoctoral research fellowships, professional development, and faculty mentoring to scholars in all fields whose research, teaching, and service advance the academic and research missions of the University of California. Since 2003, UC campuses that hire current and former PPFP fellows into ladder-rank positions have been eligible for a hiring incentive funded by the University that provides support for newly hired fellows for five years. Since the creation of the incentive, more than $162 million has been invested by the University to support PPFP faculty hires. This commitment has enabled our campuses to successfully recruit and retain outstanding faculty across a range of disciplines. Given the myriad challenges currently facing UC - including disruptions to billions of dollars in annual federal support, as well as uncertainty around the state budget- reasonable questions were raised in recent months about whether the University could maintain the commitment to current levels of incentive funding. After considering a recommendation to sunset the incentive program due to these significant fiscal constraints, I consulted with all of you as well as faculty and campus academic administrators and systemwide Academic Senate leadership. [continued on next image] After learning more about the history and success of the program and weighing the thoughtful perspectives that have been shared, I have concluded that barring extraordinary financial setbacks, the PPFP faculty hiring incentive program will continue while the University continues to assess the program's structure as well as its long-term financial sustainability. As a result of our continuing consultation and review, there may be consideration of some changes to elements of the program including the total number of incentives supported, a number that has fluctuated significantly over the years, and how the awards are distributed among campuses. In the meantime, the University will continue to fund the PPFP faculty hiring incentive program and campuses may continue to take advantage of these incentives. We will have an opportunity to discuss any potential changes prior to adoption. As we look to the future, I will continue to engage with faculty leaders, program stakeholders, and UC community members about this important program. I especially appreciate the thoughtful perspectives shared in recent weeks by Academic Council Chair Palazoglu and Vice Chair Scott, the Council of Graduate Deans, UC faculty members, and you as our campus leaders. Sincerely, James B. Milliken President

3/5 Using matched student–teacher data from North Carolina plus high-resolution weather data, I find each additional extreme heat day lowers test scores in classrooms taught by the teachers aged 54 and over. For younger teachers, I do not find an effect.
This figure plots average normalized test scores against the number of yearly extreme heat days by teacher age bin--ages below 54 or 54 and above.
