RNA-specific local translation is patterned by condensates for multinucleate cell growth - Nature Cell Biology Geisterfer, Jalihal et al. show spatially distinct effects of Whi3 condensates on target translation in Ashbya syncytia. In vitro, translation is enriched at condensate–solute interfaces but repressed...

Condensates are powerful ways to break symmetry and cells do remarkable things with them. Here we show that in a multinucleate fungus, a condensate regulates translation of a cyclin and a formin in distinct locations.

Toward universal binder discovery: Advances in display, computational design and in vivo platforms Protein binders are fundamental tools in chemical biology, key components of biotechnologies, and the foundation of biologics-based medicines. However…

Check out our new review on binder discovery! In a fast-moving world, here are some thoughts we have in the moment.

Congrats @jzy2799.bsky.social and Eddy!!

The molecular basis of force selectivity by PIEZO2 Nature - PIEZO2 is intrinsically more rigid than PIEZO1, and disparate mechanical stimuli paradoxically evoke opposite conformational and gating responses in each channel.

New paper from the lab led by @ericmulhall.bsky.social addresses how PIEZO1 and PIEZO2 are tuned to different types mechanical forces. From nanometer-scale super-resolution microscopy to in vivo experiments, links single-molecule observations to physiological function.

Silvia's simulations showed that while all epitopes expose Sia for binding, Siglec-6 recognises and binds only GM1 because of a key interaction with the membrane through W127 and K126, which orientates the V-set domain to bind the Sia through Arg122 and the terminal Gal to the C-C' loop 😎

I was sad to learn that my postdoctoral mentor, David Botstein, died yesterday. I started with David as a postdoc in 1998, and he had a profound effect on both my life and scientific career. He was a giant in the field of genetics, making seminal contributions in both yeast and human genetics. 1/

A 3D-styled pie chart illustrating the distribution of Research and Development (R&D) resources based on the NSF NCSES National Patterns of R&D Resources: 2022-23 Update.

The chart is divided into six segments, listed here in descending order of their financial contribution:

Federal Govt: The largest segment, shown in dark blue, accounts for 51% of the total, valued at $39.5 B.

Higher Ed. – Institutional: A light coral segment accounting for 23%, valued at $18.2 B.

Non-profit at Research Institutes: A dark red segment accounting for 8%, valued at $6.1 B.

Higher Ed. – Direct Philanthropy: A bright red segment accounting for 7%, valued at $5.8 B.

Business: A grey segment accounting for 7%, valued at $5.2 B.

Non-Federal Govt: The smallest segment, shown in light blue, accounting for 4%, valued at $3.2 B.

Here's a chart showing who funds basic research in the US. It's easy to tell that private funding cannot make up for significant cuts to government funding.

The mass range of tandem mass spectra can be categorized into three main regions. For glycopeptides, the lower mass range contains mainly oxonium ions, the middle range contains mainly peptide fragments, and the high range contains charge-reduced fragments. All regions contain valuable fragment ion information, but they can only be simultaneously accessed by breaking the 5–10–15 rule.

MS/MS scan range can be an afterthought that doesn't receive attention in method design, but improper settings can affect experimental outcomes. This is especially true in glycoproteomics.

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

NIH is not issuing awards. You may think that it's because they it is coming up with new directions of research...The apposite is true.

Here is a graph showing how many fewer new funding opportunities that NIH has posted over time.

-91%, a trend that started on Jan 2025.

NIH funding rate per applicant dropped 38% in FY2025 vs 2022, from 27.1% to 16.7%

Here's a breakdown by career stage. Why FY2022 vs FY2025?
• FY2022 was first FY with budget passed and administered by Biden
• FY2025 budget was in CR until 3/15/2025, so budget and most grants were under the Trump WH
