DHS is holding a 2-month-old BABY at a detention facility in Texas.

Last night, Juan Nicolás was rushed to the hospital after choking on his own vomit & being unable to breathe.

This demands accountability — not a blank check for more cruelty.

The FDA has refused to accept an application from Moderna to review its first mRNA seasonal flu vaccine, the company said, in another setback for the technology that’s been a target of some Trump administration health officials. https://cnn.it/4kt8iyn

ICE to begin detaining immigrants inside Social Circle warehouse in April Homeland Security plans to build warehouse detention facilities in other cities being met with opposition.

ICE has now spent over half a BILLION dollars just on purchasing warehouses around the country to convert into detention camps.

If these mega-camps are utilized to the full capacity ICE intends, they'll be the largest prisons in the country, with little real oversight. www.ajc.com/politics/202...

A man taken into custody in Rochester Thursday by federal immigration agents and now held at the Whipple Federal Building in the Twin Cities is a recent organ transplant recipient who is without his needed anti-rejection medication, state Rep. Kim Hicks tells MPR News.

The new updates for Charles McAnany’s preprint “Positional Interpretation of Cis-Regulatory Code and Nucleosome Organization with Deep Learning Models” (www.biorxiv.org/content/10.1...) are up!

We introduce PISA, a tool to visualize the cis-regulatory code. See a recap below:

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

It’s -9 degrees. Downtown Minneapolis is packed for the anti-ICE rally and the crowd keeps growing

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.

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.

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.

Progressive Caucus Backs Bill To Redirect ICE Money To Affordable Housing

The Congressional Progressive Caucus, a group of nearly 100 House Democrats, will announce later today that it's formally endorsing legislation to strip $175 billion from ICE and put it toward affordable housing. www.huffpost.com/entry/doj-fe...

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.

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

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." 🧵:
