Proud present our latest work led by Blessy Paul, now in Developmental Cell @cellpress.bsky.social.

Here, we characterize an ER-localized antioxidant enzyme in humans and Drosophila that acts as a lipid quality control factor to suppress ER lipid oxidation.

Paraoxonase-like APMAP maintains endoplasmic-reticulum-associated lipid and lipoprotein homeostasis
Here, Paul et al. show that APMAP is an ER-localized paraoxonase-like enzyme that suppresses lipid oxidation and redox stress at the ER network. APMAP loss leads to ER stress, redox disruption, phosph...

Out today, we report how small chemical modifications in the metabolism of ergosterol are needed for yeast membranes to phase seperate into ordered yet fluid domains www.science.org/doi/10.1126/... (1/n)
Structural dissection of ergosterol metabolism reveals a pathway optimized for membrane phase separation
The metabolism of ergosterol shapes this lipid to allow the formation of fluid membrane domains in yeast cells.

Comprehensive Identification of Lipid–Membrane Protein Interactions via Advanced Proteomics and Extended Lipid-Immobilized Bead Technology
In biological membranes, lipids interact with membrane proteins (MPs) and play important roles in allosterically regulating their structure and function. Analyzing lipid–MP interactions is necessary f...

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it — and his memory — alive.
The Coming Out of a Transgender Scientist

1) Fox News is for real not showing stock-market ticker during this week's collapse.

2) Its economic news is "strong jobs report."

3) Every time I've checked in today, the coverage has been "illegal immigrants committing new crimes."

This is state propaganda, on a par with North Korea or PRC.

I've already had two federal grants terminated and face a 33% pay cut due to future terminations. It's painful, but not as painful as the conversations I'm having every day with brilliant trainees in graduate school and postdoctoral positions who see little future for themselves in US science.
