A short-and-sweet guide to developing research questions published in @Nature. Lots of good advice here 👍

What I Wish I Knew Early in Graduate School This perspective by @anand_bhattad resonates with me. In short: > Worry less about prestige and focus on research that stands out and stands the test of time. anandbhattad.github.io/blogs/jr_grads…

NEW STUDY: Epigenetic drift is redefined as “mesenchymal drift”, with aged cells undergoing EMT, typically a cell ID alteration in development & wound healing, not diseases. Drift is reversed by OSK(M) reprogramming! Another step forward 👏 @altos_labs cell.com/cell/fulltext/…

Why does cancer incidence increase with age? Is it the accumulation of mutations? Is it a declining immune system? Are there other factors? Both mutation accumulation and immune system decline correlate with age and support predictive models of cancer rates. 🧵

Is it the accumulation of mutations? 
Is it a declining immune system?
Are there other factors?

Both mutation accumulation and immune system decline correlate with age and support predictive models of cancer rates.

Your biological age is malleable but the number you get can depend on the technology. Some DNAme clocks can be off by 15 years! New corrections (using PCA) bring noise to 0.46 a 1.1 year. The take away is that clocks need to be built to suppress technical noise to be useful

Formins are engines powering cellular acrobatics. They are Rho family GTPases that orchestrate cytoskeleton rearrangements. They can nucleate the polymerization of actin filaments, accelerate the elongation of actin filaments, and stabilize microtubules.

A group of physicists has proposed that space has memory, and the weight of information stored in space makes up dark matter. In today's video I have a look at the paper. youtube.com/watch?v=kTMRo-…

A paper from the JUMP Cell Painting Consortium presents image-based phenotypic profiles for 75% of the protein coding genome of human U-2 OS cells, offering a valuable resource for exploring gene relationships. @DrAnneCarpenter @shantanuXsingh nature.com/articles/s4159…

Have $10M and want to cure some diseases? It costs ~$1B to invent a new medicine…but $10M buys you Project Encore, to see if ANY existing drug might be repurposed for ~100 diseases that have no treatments. Contact me - be a hero for desperate patients! docs.google.com/document/d/1dM…

Cell size varies by many orders of magnitude. The mechanisms that generate and maintain this extraordinary diversity of sizes remain incompletely understood.

1/ No, you do not always need single-cell RNA-seq. Here's why bulk RNA-seq might still be the smarter move for your experiment.
