The latest work from ours and
@vram142.bsky.social
lab is out! True teamwork to visualize nascent chromatin with strand resolution, using a fully reconstituted system. Very proud of superstar-PhD student Bruna, and
@palindromephd.bsky.social
. Learning so much from Vijay’s amazing technologies! RT

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.

Doctor Behind Award-Winning Parkinson’s Research Among Scientists Purged From NIH
Leading scientists at the National Institutes of Health, the US’s leading medical research agency, were swept up Tuesday in the Trump administration’s latest firing blitz.

Trump's 3/27 executive order targets the Smithsonian for advancing "the view that race is not a biological reality but a social construct." Trump argues that the exhibit's statement, below, is unscientific. He's wrong. As a biology professor and population geneticist, I agree with every word of it.

It's infinitely sad to see what is happening. the disregard of laws, advice and justice in our immigration policy plans, the total implosion of human values overseas. I feel just a bystander reeling in shock.

Today Jan Drenth would have been 100 years, but sadly he passed away last week. He was the founding father of structural biology in the Netherlands and his modesty, his gentle humor and his generosity set the spirit for the amazing environment in Groningen where i did my PhD.

We have an opening for a PhD student, for a cryo-EM/biochemistry project at the interface of ubiquitin and DNA repair. Enthousiasm and experience with protein biochemistry and/or structural biology really important. Recruitment will fall under the the NKI PhD program, please see below

Excited to report our discovery of an important component of the oxidative stress response: the E3 ligase TRIP12. It acts as a chain elongation factor that amplifies CUL3-KEAP1 activity to drive NRF2 degradation as cells recover from stress.

The oxidative stress response is centered on the transcription factor NRF2 and protects cells from reactive oxygen species (ROS). While ROS inhibit the E3 ligase CUL3-KEAP1 to stabilize NRF2 and elici...

Next up, microscopy nodes for Blender, made by
@grosoane.bsky.social
, which lets you import microscopy images as efficient voxel representations for generating animations (ie below, from EMPIAR-10982). I've had a lot of fun playing around with it the last couple of weeks.
