Physicist & chemist Marie Curie was the: + First woman to win a Nobel Prize + First person & only woman to win twice + Only person to ever win a Nobel Prize in 2 different sciences: Physics (1903) & Chemistry (1911) Marie Skłodowska Curie died #OTD in 1934. #WomenInSTEM

A striking black-and-white studio portrait of Marie Curie (1867–1934), the legendary Polish-French physicist and chemist who revolutionized modern science by discovering radioactivity, polonium, and radium. As the only person to win Nobel Prizes in two different scientific fields, her profound historical significance is reflected in her serious, deeply introspective expression. Photographed from the chest up, she looks directly at the camera with an intense, analytical gaze. Her graying hair is styled in a soft updo, framing a face etched with a look of quiet resolve and intellectual focus. She wears a dark, textured jacket over a shirt adorned with a distinctive geometric, black-and-white checkered pattern at the neckline. The portrait utilizes a stark, dark, textured background that blends into her clothing, creating a high-contrast composition that draws complete focus to her face. The overall mood is solemn, dignified, and powerful, capturing the essence of a brilliant academic pioneer who dedicated her life to scientific discovery.

Yup, this would have brought together experts to share the latest findings on respiratory virus transmission. The meeting is canceled, but the continuing spread and evolution of H5N1 and other respiratory pathogens is not. In the middle of the game, the defense is walking off the field.
