Hey look, Israel broke the cease-fire, twice, in two different ways, within 24 hours - again.

NEW: Israel informed the UN it will permit only 300 aid trucks into Gaza daily, not the 600 mandated by the ceasefire it just signed.

We used live-cell imaging with plus-end binding protein EB3 to determine microtubule polarity in astrocytes for the first time. They are ~88% plus-ends out.

Indiana University fires IDS
adviser amid push to control
student newspaper's content The director of student media at Indiana University was fired amidst a dispute between university leadership and editors at the Indiana Daily Student over what content gets printed in the student newspaper.

As director of student media, Jim Rodenbush did not directly oversee or have any say over the content published in the IDS, per a charter between the IDS and the university. But he told IndyStar his firing follows a series of meetings with IU Media School leadership in which it grew increasingly apparent they were expecting him to officially prohibit students from publishing news.

Not that anybody comes to me for Maine politics, but the fact that the Democrats successfully convinced a 77yo Governor to primary the 41yo progressive, is today's example of why the Democrats fucking stay failing.

Susan Collins is 72 and if Schumer gets his way, she'll be the YOUNGER choice!

This is the life-saving work that the Trump Regime is doing its best to destroy.
I have to add: please note that this work is the result of long years of university research, much of it federally funded. And note that the years (decades) of less-successful attempts that have led up to these papers are in the same category: NIH and NCI money are all over this field. This is the very thing that the Trump administration has been working tirelessly to destroy. I am not exaggerating. They have been hitting these funding agencies over and over with layoffs, budget cuts, and whatever obstacles they can dream up, and they are also ripping into the universities where these funds have been granted. The exact phrases that J. D. Vance, Stephen Miller, Russell Vought and their henchmen have used is "universities are the enemy" and federal workers "need to be put into trauma". More specifically, the  attitudes of our HHS head (RFK, Jr.) and his own minions toward mRNA research and vaccination are easy to summarize: they hate it and they want it to stop. It seems bizarre and insane and almost impossible to believe, but that is exactly what is happening. Every time you see scientific progress being made from US universities, remember that our elected officials are trying every day to defund it, to cripple it, to kill it outright. They are hitting it again and again in the hopes that it will finally stop moving. Act accordingly.

The “Thorin” genome from Mandrin Cave, France, comes from a Neanderthal individual that might not have attracted much notice from the teeth and jawbone on their own. His DNA shows a deeper story of dynamic movements of some groups and long stasis of others.

Just so everyone is clear, the main issue in the Supreme Court voting rights case tomorrow is whether it's racist against white people to enforce the Voting Rights Act.

I'm dead serious. We live in incredibly stupid times.

Trump has no legal authority, "standing" or otherwise, to order the killing of people in international waters for unsubstantiated accusations of non-capital crimes.

Calling them "narcoterrorists" does not make it right or legal to order their deaths without any due process.

Trump announces another strike "just off the Coast of Venezuela" that killed 6 people
Under my Standing Authorities as Commander-in-Chief, this morning, the Secretary of War, ordered a lethal kinetic strike on a vessel affiliated with a Designated Terrorist Organization (DTO) conducting narcotrafficking in the USSOUTHCOM area of responsibility — just off the Coast of Venezuela. Intelligence confirmed the vessel was trafficking narcotics, was associated with illicit narcoterrorist networks, and was transiting along a known DTO route. The strike was conducted in International Waters, and six male narcoterrorists aboard the vessel were killed in the strike. No U.S. Forces were harmed. Thank you for your attention to this matter!!!!!!

Currently on a flight to Japan watching a Pentagon Assistant Press Secretary (Riley Podleski) work on a document in the open on her laptop. She spent the last hour copy and pasting headlines from articles critical of the Administration’s hostility toward the 1st amendment.

How to recognize a Young Republican douchebag in the wild.
Young Republican douchebag oozing towards the camera Young Republican douchebag blabbering from a lectern. Young Republican douchebag smarmying smarmily. Young Republican douchebag, or possibly an incel. It’s hard to distinguish. The glasses sort of imply “Youth Minister” and therefore pedophile but hopefully he’s just a racist dick.

Here is GOP Rep. Mike Lawler, all smiles with the Chair of the NY State Young Republicans Peter Giunta who:

*Said ‘I love Hitler’

*Referred to blacks as ‘the watermelon people’

*Said ‘if your pilot is a she and she looks ten shades darker than someone from Sicily, just end it there.’

I am being asked to tell my department which pieces of lab equipment should be supported with backup power because they expect rolling blackouts and brownouts in 2026 due to increased energy demands from AI. In case you're wondering how my day is going.

Just heard about a 30-yr JPL scientist that was laid off. Had an email from them about one of our projects at 1PM. Three hours later: fired.

Again, if JPL leadership were actively trying to destroy morale, would they be handling the layoffs any differently?
