Advisory Committee on Immunization Practices at a Crossroads In this Viewpoint, former members of the Advisory Committee on Immunization Practices (ACIP) caution that the sudden change in the ACIP may reverse the achievements of US immunization policy, includin...

👀 Hot off the press: A scathing open letter co-authored by all 17 former ACIP members. It's a frank look at ACIP history and the hard truths America will grapple with in the upcoming months.
Turns out the former ACIP members have more spine than CDC leadership 🙄

Do you have good tips on engaging? It's been hit or miss with me and whoever is on the line.

Implementation of Schedule F

This is what a lot of us have been worried about.

This allows for many civil service positions to replaced with political appointees. This could include NIH institute directors and even POs.

BUT THERE IS A COMMENT PERIOD...

Amazing women in science having hotpot @drstarbird.bsky.social @berlowlab.bsky.social

Calling all membrane/membrane protein folks! Join us this summer in Barcelona for the Membrane Protein Folding Gordon Conference and Seminar. GRS chaired by @justmwest.bsky.social and myself! We are soliticiting abstracts from trainees for talks! Deadline - April 6.

The Tortured Proteins Department Podcast · Stephanie Wankowicz · A deep dive into scientific discovery and the process of doing science, hosted by Stephanie Wankowicz and James Fraser.

Since @stephanieaw.bsky.social left the lab to start her group at Vanderbilt, we've been talking regularly on the ups and downs of academic science. We started recording...

I got laid off today, with the rest of 18F.

18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it.

We made this website to tell our story:
18f.org

I took the stage at the #BPS2025 meeting in solidarity with our american colleagues.
On March 7th, events and protests are organized in US and other countries, including France, to #standupforscience

The foundations of America’s prosperity are being dismantled Federal scientists warn that Americans could feel the effects of the new administration's devastating cuts for decades to come

For decades, the US government has painstakingly kept American science #1 globally—and every facet of American life has improved because of it. The internet? Flu shot? Ozempic? All grew out of federally-funded research. Now all that's being dismantled. 1/ www.technologyreview.com/2025/02/21/1...

So thrilled for you!!!!

A diagram illustrating the evolution of protein functionality through sequence and chemical space. ABLE (bottom left): Depicted as a helical bundle binding the drug apixaban, labeled as a "specialist" in binding apixaban. Its binding site is shown as a filled cavity with the drug's structure. ABLE as a generalist (center): After fragment screening, ABLE evolves to weakly bind various small molecule fragments, shown in a diverse array within the cavity. This transition highlights the exploration of chemical space. FABLE (top right): Derived from fragment-inspired design, FABLE binds turn-on fluorophores. The binding site is reconfigured to fit fluorophores like Cou485, with their chemical structures displayed. KABLE (bottom right): Another fragment-inspired evolution turns ABLE into KABLE, a Kemp eliminase. The structure of the substrate (5-nitrobenzisoxazole) is shown, with the binding site adapted for catalysis. The axes represent "Sequence Space" (vertical) and "Chemical Space" (horizontal), emphasizing how the protein evolves through these dimensions to achieve specialized functions. This schematic encapsulates the journey of ABLE from a specific binder to a generalist and then into two specialized proteins with distinct functionalities.

Thrilled to take a break from doom and gloom to share our latest work collaborating with the DeGrado lab! We took a de novo designed protein, screened it for ligand binding using X-rays, and used the hits to evolve two wildly different functions: fluorescent turn-on and Kemp elimination catalysis. 🧵

I believe in you 100%. You got this!!!!

Step Edge Defects Have Nanoscale Impact on the Electronic Structure in Semiconducting Transition Metal Dichalcogenide Electrocatalysts This work uses MoTe2 single crystals to address the challenge in heterogeneous catalysis of identifying active sites and determining the electronic factors responsible for catalytic activity. We find ...

Excited to share our latest work in JACS!! We show that step edge defects have nanoscale impact on electronic structure in semiconducting TMDC electrocatalysts. Congrats to first-author Kenneth Ortiz Chua! pubs.acs.org/doi/10.1021/...
