The possibility of losing a 3-mile loop of road has stirred fears among the runners, cyclists, fishermen, birders and others who use it. Lawmakers are beginning to raise concerns about Ohio Drive in East Potomac Park, too.

Always great to see a paper on BioRxiv that reaches the same conclusions, using similar lines of evidence, to a paper that we put on BioRxiv 7 months ago and published in PNAS a month before theirs was posted — but doesn't cite our work. Here's our paper.

Is there a recent review that summarises all the biggest, baddest, most mind-boggling #cryoEM structures out there? What I need is basically just 10 pages worth of "look at this crazy thing!" Suggestions welcome! 😆

⚠️ Be careful with VoteSafe .org. It is NOT an official voting website. It’s tied to Elon Musk’s America PAC and collects a lot of personal information from people who use it. Before you hand over your name, address, phone number, email and voter information, know who you’re giving it to.

Based on the guidelines we issued yesterday, please obtain prior approval for the collaborations you began years ago.
NIH: Does work outside of the U.S. require prior approval?
Foreign components are defined as a significant scientific element or segment of a project outside of the United States.

Significant work performed by a researcher in a foreign location qualifies as a foreign component, whether or not NIH funds are expended.

All foreign components must receive NIH prior approval.

Other examples include, but are not limited to:

the involvement of human subjects or animals at a foreign site,
extensive foreign travel by recipient project staff for the purpose of data collection, surveying, sampling, and similar activities,
collaborations with investigators at a foreign site anticipated to result in co-authorship,
Note, that while not all co-authorship situations represent a true collaboration, the NIH indicates that all cases of foreign co-authorship should be reported to the NIH funding Institute or Center as soon as recipients are aware of it. Review more information and details on NIH International Co-Authors and NIH: NOT OD-26-084
use of facilities or instrumentation at a foreign site; or
receipt of financial support or resources from a foreign entity.
All foreign components must receive NIH prior approval. If a PI is unsure if foreign activity may qualify as a foreign component, err on the side of seeking prior approval.

NOTE: The NIH has not yet provided guidance for how to request the addition of more international project components to an existing awarded PF5 project. NOT OD-25-155.

International activities may also require the UW’s International Activities Assessment.
