well put! "...while Development's IF is modest, researchers in our field trust papers published in our journal as interesting, valuable and robust science that stands the test of time... It is our Academic Editors and the Development name that define our standards, not a number."

Great visit back to UPenn today for distinguished lecture series. Saw so many old friends and mentors. Doing your PhD and postdoc at the same school also means you can go to dinner with your grad school advisor (Meera Sundaram) and postdoc advisor (Wenqin Luo).

There is a straightforward mechanism for the public to comment. Former NIH program office Elizabeth Ginexi has written an exceptionally helpful guide on how to so, with detailed suggestions. 3/n elizabethginexi.substack.com/p/what-we-ne...

Russell Vought, Director of the OMB, has issued a set of proposed changes that would dramatically alter federal grant funding. However, we can each take action to prevent these from taking effect. Here's how, a 🧵 🧪 1/n www.science.org/content/arti...

The current moment is one of the most consequential for science since World War II. Join us this afternoon. I have the privilege of moderating the panel that follows.

TODAY at 3 pm ET, don't miss NAS President Marcia McNutt deliver the third annual #StateoftheScience address, where she will explore the status of the U.S. research enterprise, global science leadership, and economic competitiveness. Join here: www.nationalacademies.org/events/1133

This is so stupid

🧵 Public science in the US has taken some heavy hits over the last year, but the White House OMB is proposing a series of changes that will result in a TKO for science as we know it unless we fight back. Here's what's happening, and why it matters. 1/n

There are people still living who fought — and watched their compatriots be murdered — for the passage of this act and to attempt to democratize America. To see it completed felled in the span of their OWN lifetime is just absolutely devastating.

Please repost! This comes from the good people at ChimeraX, who produce powerful up-to-date software to study protein (etc) structures, which are FREE to the community. 🙏 To stay viable and serve us, they need an experienced structural biologist to assume the leadership role on a funded project.

Happy Tax Day, New York. We’re taxing the rich.

It is with great sadness that I'm sharing the news that Dr. Don Moerman passed away this weekend. He was such a legend in the #Celegans and Canadian science community.

New preprint! "A stereotyped glial attachment determines the morphology and function of neuronal cilia" doi.org/10.64898/202... We find that C. elegans neuronal cilia attach to glia, we identify a protein required for cilia-glia attachment, and we show that glial attachments alter cilia signaling.

Velvet worms shoot rapid-hardening glue at their prey (other invertebrates). Within seconds, the sprayed liquid hardens to plastic-like consistency, trapping or slowing the target. This marvelous glue has possible human applications in recyclable bioplastics & surgical sutures that dissolve.

"Our findings identify ECM composition and mechanics as a primary mechanism governing mammalian regeneration. By demonstrating that the ECM acts as a mechanochemical signalling hub, we show that “retuning” the physical environment from a stiff, collagenous state to a soft, HA-rich state can.."

25th amendment. Impeachment. I will support any avenue to remove Donald Trump from office. We cannot leave this man in charge of America’s nuclear weapons as he threatens to end an entire civilization. And Congress must not fund this reckless administration.

After Trump wrote, in reference to Iran, “A whole civilization will die tonight,” the entirety of the House Democratic leadership issued this joint statement:

Trump’s statement is a direct call for war crimes. It’s deranged and sick coming from anyone, let alone the president of the United States. Any Republican who remains silent is complicit. GOP majority leadership must bring Congress back to DC NOW and rein in Trump’s warmongering. Enough is enough.

The President just threatened genocide. The Joint Chiefs of Staff must disregard any such military orders that violate federal and international law. Republicans in Congress can't hide anymore: we must consider all options – including impeachment – to stop Trump.

Anyone else notice @fetterman.senate.gov lost his “moral clarity” right around the time Trump was threatening war crimes?

In an age of creeping relativism, a universal moral law still exists. Threatening to end an entire civilization of 90 million people in order to bend a nation’s conduct to your will is grossly morally wrong. It is evil. And we should say this loudly.

Completely unstable and perilous. The House must bring up impeachment articles, and the Senate needs to remove a president who wants to commit war crimes. We cannot sit idly by as Donald Trump threatens to end an entire civilization.

How did we arrive at weak pushback against heinous war crimes? Because our media treats war like sport. Instead of questioning the legality of a war sold on false pretenses, we get critiques of strategy and timing. These are matters of International Humanitarian Law and Nuremberg, not gas prices.

TODAY: Iranians are forming human chains around civilian infrastructure (bridges, power plants) as Trump threatens to kill them all

This is crazy and completely reckless. Speaker Johnson and House Republicans need to bring us back into session immediately to stop Trump’s power-hungry regime-change war. He’s killed thousands of people, and he doesn’t care if he kills a thousand more.

The President is openly threatening genocide. A crime against humanity. He must be removed from office. The 25th Amendment must be invoked. If not, Congress has to do our damn job. Speaker Johnson, call us into session. War powers & impeachment. Remove this man from office.

Great to see this out. Practical guidance on how to use protein depletion systems in C. elegans
