First ai ruined dashes, now it has also ruined UIs with gradients and rectangular divs with lots of padding and large corner radii

Been calling senators/reps offices a lot lately but just had a real human staffer pick up for the first time to listen to my comment. This tells me their lines are not busy enough! Fill up their voicemails!

Any one of these daily atrocities should result in a full congressional investigation and a disbanding of the agency. The fact that it’s all just shrugged off by those with the power to stop it is a national disgrace.
ICE ended up returning the man, Saly, after realizing he’s a fucking US citizen with no criminal record, per his sister-in-law. These fucking animals.

Wrote a summary of a great keynote by @zey.bsky.social at NeurIPS, arguing that we’re having the wrong nightmares about AI: not AGI or superhuman benchmarks, but good-enough genAI at scale threatens "load bearing frictions" society relies on to signal effort, authenticity, sincerity, credibility.
Zeynep Tufecki on having the wrong nightmares about generative AI
I was writing a blog post where I was going to reference Zeynep Tufecki’s 2025 NeurIPS keynote, and realized there isn’t a solid synopsis online.

Today at 34 & Park in Minneapolis, a woman tried to drive down the street where a protest had broken out in front of a home ICE was raiding, saying she had a doctor apt to get to. ICE agents busted out her windows, cut off her seatbelt, and pulled her out before arresting her.

A video of ICE agents conducting door-to-door searches today in Minneapolis

The homeowner requests a warrant repeatedly, is told they don't require one, then is told they're getting it, then the agents storm in anyway

They also point a taser at her to try and disrupt filming

A new paper from Stanford adds further, incontrovertible evidence that LLMs memorize training data.

The authors showed that copyrighted works can be extracted from every LLM they tried: GPT-4.1, Gemini 2.5 Pro, Grok 3, and Claude 3.7 Sonnet.

🎉 New year, NEW PREPRINT!

Bacteria exhibit astonishing genetic diversity, but where do new genes come from?

My best friend Arya Kaul (/labmate in the @baym lab) investigates how advantageous deletions can spawn new genes - "deletion-born fusions." 🧵:
Novel genes arise from genomic deletions across the bacterial tree of life https://www.biorxiv.org/content/10.64898/2026.01.05.697752v1

7/ Here's the bottom line: This is an unprecedented shift that risks weakening protection against preventable diseases at a time when outbreaks are rising and children are already being hospitalized. Vaccines don’t work without strong supporting systems...and the U.S. doesn’t have Denmark’s.
