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. 🧪

Full Pew Research Center report: https://www.pewresearch.org/internet/2025/11/20/americans-social-media-use-2025/
Chart showing change in the use of online platforms. Over the past few years, four of them have grown in overall use among U.S. adults – TikTok, Instagram, WhatsApp and Reddit. TikTok: 37% of U.S. adults report using the platform, which is slightly up from last year and up from 21% in 2021. Instagram: Half of U.S. adults now report using it, which is on par with last year but up from 40% in 2021. WhatsApp and Reddit: About a third say they use WhatsApp, up from 23% in 2021. And 26% today report using Reddit, compared with 18% four years ago. While YouTube and Facebook continue to sit at the top, the shares of Americans who report using them have remained relatively stable in recent years.

🧵Why I'm loving cluster photometry. Point a telescope, measure brightness in B and V filters, and suddenly thousands of stars tell a single story: temperature, evolution stage, and where the cluster sits in space. Short, sharp, and addictive. 1/6 🧪🔭

so yeah, your students should learn basic physics, not just what's immediately required for their specialty

20 years ago there was huge pressure to train for “financial physics”, then computer science, now AI. And while a good physics program will give exposure to tools relevant for the area of the day, it will strongly resist focusing on that area and instead focus on the fundamentals.

Those claiming Dems should retreat on racial justice aren't hard-headed realists, they're pushing against the electoral tide rather than leaning into it. The story of Gen Z isn't about racist backlash or red-pilled young men. It's the most racially progressive generation in American history. 🧵
Racial Resentment Among White Americans by Birth Year and Demographics This figure presents the same four-panel layout (education, gender, geography, religion) but for White Americans from birth years 1940 to 2000. Education panel: A pronounced divide shows non-college Whites with substantially higher resentment across all cohorts, increasing sharply for older birth years. College-educated Whites rise more modestly but remain distinctly lower, especially among younger cohorts. Gender panel: Male and female trendlines rise together, with women slightly higher in mid-century cohorts. Younger cohorts of both genders start lower and climb with age. Geography panel: Regional lines separate clearly: the South is highest in resentment, followed by the Midwest. The West and Northeast show lower levels, with the Northeast consistently at the bottom. All regions slope upward toward older cohorts. Religion panel: Protestants show the highest resentment, peaking among mid-century cohorts. Catholics sit in the middle. Non-affiliated Whites show the lowest resentment, especially among younger respondents, with a small rise among mid-century generations. The figure notes CES 2024 data with GAM-smoothed trendlines.

Ever handed your students a “ready-to-paint” dataset?

In our latest Learning Progressions Blog post, Tim Erickson shows why students should help prepare the data—filtering, grouping, and summarizing—before diving in.

📢 #EdWorkingPapers: Do K–12 computer science education policies boost CS majors in college?

Using 20+ years of data, Paul Bruno & colleagues show these policies are often too light-touch to matter, reflecting, not driving, rising CS interest.

Australia has so much electricity from solar power that it is going to start offering free electricity to everyone for at least three hours during the day as the wholesale price of power goes negative

Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

🔭 ~1,400 people globally have contributed to the construction of Rubin, including

500 construction staff,
500 contractors,
100 staff on operations (so far), and
300 in-kind contributors, from software and hardware contributions to follow-up observing time on other telescopes

On Tuesday at the WeTeach_CS Summit, Dr. Stella Offner will share with CS educators how CS and AI can lead to new science. Below are animations from the STARFORGE showing a simulation of star formation (Guszejnov et al. 2021, Grudic et al. 2021).

An object called 2017 OF201 is shaking up our ideas about the outer zone of our solar system.
It follows an extreme, 25,000-year orbit.
It may be 1 of 100s of such bodies filling a seemingly vacant region.
And its existence casts doubt on searches for Planet 9. 🧪🔭

www.ias.edu/news/extreme...
Plan view of the orbits of TNOs (trans-Neptune objects) with extremely wide orbits, including our newly discovered 2017 OF201, which has a distinct orbit is an outlier to the apsidal clustering of the others. For reference, the most probable orbit of Planet X from Siraj et al. (2025) is shown in white.

A recent paper led by collaboration members Yoonsoo Kim and Elias Most (both at Caltech) is in @aasnova.org today! This work explores the formation of strongly magnetized "monster" shocks and a transient "black hole pulsar" state from mergers of a magnetized neutron star and a black hole.
