This is insane. All because Donald Trump launched a war with no plan and took away your healthcare.

Americans deserve relief now. We’ve paid enough.

Excited to share our paper about copick, a dataset API and toolkit for collaborative annotation and analysis of #cryoET data! Whether you're picking particles or curating segmentations, copick reduces friction and brings #OME-Zarr to cryoET without breaking pipelines.

This black-and-white studio portrait photograph captures Rosalind Elsie Franklin, the brilliant British chemist and X-ray crystallographer whose meticulous research produced Photograph 51—the iconic X-ray diffraction image that revealed DNA’s double-helix structure and proved pivotal to the 1953 Watson-Crick model of the molecule. Shown in a close-up, three-quarter view from the shoulders up, Franklin appears in her late twenties or early thirties, her dark, wavy hair neatly styled and swept back from her face. She wears a simple, dark collared blouse or shirt with a crisp, professional appearance that reflects the understated elegance typical of mid-20th-century scientific women. Her expression is calm and intensely focused: direct gaze slightly off-camera to the viewer’s left, lips gently closed in a subtle, knowing half-smile, conveying quiet confidence, intellectual depth, and quiet determination. The plain, softly lit studio background with its neutral gradient emphasizes her face and upper torso, creating an intimate, timeless composition that places her poised presence at the absolute center.

Chemist & X-ray crystallographer Rosalind Franklin's meticulous research was instrumental in uncovering DNA's molecular structure.

Most famous for her role in the DNA double helix discovery, her work also revolutionized our understanding of viruses & coal. Died #OTD in 1958, age 37. #WomenInSTEM

Armed masked man at Hamilton High protest identified as Phoenix police sergeant A recent police report says an armed, masked man who showed up during an anti-ICE student walkout three months ago at Hamilton High School is a Phoenix police sergeant.

He was trying to bait kids into assaulting him. Just because unfathomably stupid behavior.
