No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...
Gladys Mae West obituary: mathematician who pioneered GPS technology
She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

After four months, the journal has not found a single reviewer for my PhD student's manuscript. The academic peer review system is broken.

I think we all should:

1. Review three papers for every one that we submit.
2. Promptly declined to review a paper when the request arrives.

#AcademicChatter
A table with columns "Stage" and "Start Date" tracks the multi-month editorial progress of a manuscript submission from October 2025 to January 2026. The log begins on October 8, 2025, with "Preliminary Manuscript Data Submitted," and moves through several administrative phases including "Initial Quality Control" and the assignment of Editors and Associate Editors by late October. Starting on October 26, 2025, the status begins an oscillating cycle between "Contacting Potential Reviewers" and "Waiting for Reviewer Assignment," appearing multiple times through November and into early 2026. The most recent entries show "Contacting Potential Reviewers" on January 12, 2026, followed by a shift back to "Waiting for Reviewer Assignment" on January 13, 2026, indicating an ongoing search for peer reviewers. This has continued until the last update on January 26, 2026

Remembering Dr. Maryam Mirzakhani on #WorldCancerDay.

Dr. Mirzakhani was first woman to win the Fields Medal, the most prestigious award in #mathematics. She died in 2017 from #breastcancer at the age of 40.

stanford.io/2C0io2A #WomenInSTEM
A vibrant, composite portrait of the brilliant Iranian mathematician Maryam Mirzakhani (1977–2017), the first woman and first Iranian to win the Fields Medal. She is shown in a close-up head-and-shoulders view, facing the camera with a gentle, thoughtful expression—short brown hair, bright blue eyes, and a calm smile. She wears a navy blue fleece over a teal/green collared shirt. Overlaid transparently behind and around her is a dense blackboard filled with intricate handwritten mathematical equations in white chalk, featuring complex expressions involving binomial coefficients (e.g., n! / (k!(n-k)!)), factorials, summations, powers, and terms suggestive of hypergeometric series or combinatorial identities. The equations partially surround and frame her face, symbolizing her deep immersion in advanced mathematics, particularly in hyperbolic geometry, Teichmüller theory, and dynamical systems, while evoking the creative, exploratory nature of her work as a Stanford professor and groundbreaking researcher.

i was actually shocked to see the numbers on new research from Global Energy Monitor on new gas projects in the US: nearly 100 gigawatts of power—enough to power tens of millions of homes—are currently in development explicitly to power data centers. At the end of 2023 that number was 4 gigawatts

Gas projects in the US pipeline explicitly linked to data centers increased by almost 25 times over the past two years, according to new research from Global Energy Monitor.

"14% of Ph.D.s in science, technology, engineering, and math (STEM) or health fields" stopped working for the US federal gov't in 2025"
"10,109 doctoral-trained experts"
doi.org/10.1126/science.zw5s0b4
This graphic shows a sharp, across-the-board contraction of the U.S. federal STEM Ph.D. workforce in 2025, compared with 2024, across 14 science-intensive agencies. The horizontal bars plot **departures to the left** and **hires to the right**, with lighter colors for 2024 and darker colors for 2025. For every agency, the 2025 departure bar is substantially longer than the 2024 bar, while the hiring bar shrinks markedly. There are no exceptions: **all 14 agencies lost far more STEM Ph.D.s in 2025 than the year before**, and all hired fewer. The **largest absolute losses** occur in the Department of Health and Human Services. The **National Institutes of Health** stands out most clearly, with **over 1,100 STEM Ph.D. departures in 2025**, compared with **about 421 in 2024**, despite being the single largest employer of STEM Ph.D.s in the federal government. The **Food and Drug Administration** and **CDC** show similarly large increases in departures and weaker hiring. Across agencies, the pattern is not just absolute but proportional. On average, the figure reports **roughly three times more STEM Ph.D.s leaving in 2025 than in 2024**, and **11 times more losses than gains** when departures are compared with hires in 2025. Particularly steep percentage increases in departures appear at **NOAA**, the **Environmental Protection Agency**, and the **U.S. Forest Service**, even though these agencies are smaller than NIH.
