Congratulations to our lab's first graduate student, @kristinaelopez.bsky.social, for successfully defending her thesis! Tina tackled one of liver regeneration's oldest mysteries with unabashed persistence and zero fear of a tough experiment. Stay tuned for the full story!

Angelika showed us all how to pursue science with limitless enthusiasm, rigor, and generosity. Excited to announce the call for this year's Angelika Amon Young Scientist Award! Please encourage PhD students outside the United States who embody her infectious passion for biology to apply.

New preprint on technologies to scale up CRISPR screens. We use them to map 665,856 pairwise genetic perturbations and outline a path to comprehensive interaction mapping in human cells. We also introduce an approach for cloning lentiviral libraries with billions of elements.

Axolotls are famous for regenerating limbs. Turns out they can also regenerate their thymus—and that may show us how to someday to the same. That story and more of the best from @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪

ACOG reaffirms that acetaminophen is safe for managing pain and fever during pregnancy. No reputable studies support suggestions like those in HHS’s recent announcement linking acetaminophen use in pregnancy to autism; in fact, high-quality studies show no such risk. https://bit.ly/47Wxc59

The Garnett Lab is excited to launch DepMap Miner, a new tool to explore cancer dependency data! Built on the Sanger DepMap, the DepMap Miner brings together multi-omic and functional datasets for over 1300 cancer cell models. Start mining data now: dataminer.depmap.sanger.ac.uk

New preprint! Graduate student Océane Marescal leverages quiescence - proliferative hibernation - to reveal unexpected dynamics for “constitutively”-localized centromere proteins. To understand the logic of cell division, you need to consider non-dividing cells. www.biorxiv.org/content/10.1...

The dynamics of centromere assembly and disassembly during quiescence

Quiescence is a state in which cells undergo a prolonged proliferative arrest while maintaining their capacity to reenter the cell cycle. Here, we analyze entry and exit from quiescence, focusing on h...

Doomscrolling pause to chat CRISPR libraries! Preprint describes our new, data-driven approach to combine on-target and off-target predictions much more intelligently for *selecting* guides, which we use to develop our newest Cas9 knockout library, Jacquere. Thread: www.biorxiv.org/content/10.1...

Balancing off-target and on-target considerations for optimized Cas9 CRISPR knockout library design

The continued development of high-dimensional CRISPR screen readouts, such as single-cell RNA sequencing and high-content imaging, necessitates compact libraries to enable functional interrogation at ...

Lab retreat 2025 was a reel good time!

Congrats to Sourav Ghosh (@souravsgw.bsky.social) of IIT Bombay & Kotaro Tomuro of RIKEN and The University of Tokyo - our 2025 Amon Young Scientist Award winners! They present Nov 6, 10 a.m. at the Koch Institute. MIT community & Amon Lab alumni welcome. buff.ly/nzhbwPp

Our liver can completely regenerate itself in a matter of days! Excited to share this perspective on how the liver breaks the rules of cell biology to accomplish this exceptional feat and how this could unlock regenerative capacity in other organs. www.molbiolcell.org/doi/10.1091/...

Breaking the rules of cell biology: Lessons from the liver's exceptional regenerative capacity | Molecular Biology of the Cell

The inability of most human organs to regenerate themselves after injury underlies the lifelong morbidity of numerous diseases. As we continue to seek solutions for these intractable conditions, the l...

Preprint alert!! How zonated hepatocytes adapt to changes in lipid influx due to fasting or a Western diet (WD). We developed a microscopy-based phenotyping method called single-cell phenomics (scPhenomics) to measure the features of mitochondria and lipid droplets (LDs).

How did we get here, with a prominent anti-vaxxer nominated to lead Health and Human Services, with its $1.7T budget? Much of it can be traced to this retracted 1998 paper, falsely linking the measles, mumps and rubella (MMR) vaccine to autism. 1/3
