Historian of science Margaret Rossiter (d #OTD in 2025) coined the term #MatildaEffect (1993). Named after suffragist Matilda Joslyn Gage, the Matilda Effect describes a systemic bias where women's scientific achievements are ignored, minimized, or directly attributed to their male colleagues. 1/3

💯 oh my. This is a milestone event. Many of us enjoy the help an "AI thought partner" brings to our own lives - in dozens of ways, small and large. Yet we recognize a need for greater vigilance, and strong safeguards to keep these helpmates from spawning feral progeny..
Hugging Face detected and contained the breach on July 16, 2026 , and OpenAI published its version of events five days later.
Electric bills are way too high — particularly PG&E — and plug-in solar is a great way to lower those bills. I’m authoring legislation to allow Californians to easily use these devices; it’s currently quite hard, if not impossible, for people to do so.
California bill backs plug-in solar as PG&E rates soar, and renters could save on power

Trees take years to grow. A mature tree that's been standing for decades can be felled in minutes. That gap—between the time it takes to build something and the time it takes to destroy it—is worth sitting with. It's why thoughtful land use matters.

Canada's first female nuclear physicist Harriet Brooks (b #OTD 1876) was a researcher in the early days of nuclear science. Her work on radioactivity laid foundational groundwork for modern nuclear physics. She discovered the phenomenon of atomic recoil. But, her career ended early. #WomenInSTEM 1/2
Today we celebrate the 150th anniversary of physicist Harriet Brooks's birth. Before marriage compelled her to give up her career, she was one of the world's most significant nuclear physicists, discovering the phenomenon of nuclear recoil, credit for which was stolen from her. tinyurl.com/mvcd3ape
