I currently live a “double life”: I am both a Staff Scientist in an academic lab and Founder/CSO of a small biotech startup @hagabio.bsky.social . This is not super common, so I thought I’d put together a thread clarifying how this works, at least for me.

Surprised to discover that Thermo Fisher appears to show a fake western blot for the validation of one of their p53 antibodies. I've added a diagram to show the very similar bands. This does not appear to be one of the "published figures" but their own internal data.

of many projects Craig Venter led, of personal significance was the fly genome, a unique and i think unexpected collaboration of his company Celera Genomics and the BDGP, led by my pd advisor Gerry Rubin. the power of a shotgun sequenced metazoan, benchmarked to a physical map, transformed genomics.

We’re unwrapping a new method today at @mskcancercenter.bsky.social. Led by Sydney Blattman, Nabih Maslah, and @austinv11.com with @danapeer.bsky.social, @ronanchaligne.bsky.social and @10xgenomics.bsky.social, we present GIFT: Genotyping In Fixed Transcriptomes www.biorxiv.org/content/10.6... 1/n

Capturing somatic mutations in single-cell probe-based assays (ie. 10X Flex) is a hard task, especially if you don't know *exactly* the mutations you want to capture, or if your target sequence is a mutational hotspot with many possible alternative alleles. Here's the way we pulled this off. Enjoy!

Let me introduce you to KaroSpace, which is a rapid-access framework for interactive exploration of multi-sample spatial omics data. The preprint can be accessed here: www.biorxiv.org/content/10.6...

Do you work with a strange model species and are frustrated by the lack of antibodies for immunos? Here's a web app that does some computational pre-screening for you. sixpack-abscan.serve.scilifelab.se

In animals with large genomes, finding cis-regulatory elements can be very challenging. Enhancers can be located tens/hundreds of kb away from their target promoters. We face this challenge in Parhyale, with >3 Gbp genome. We just published a preprint describing how we are tackling this problem. /1

I am very happy (and a bit scared) to present to you what we have been working on over the last 4 years. This manuscript is exactly what I dreamt of when I started the lab and I could not be happier and prouder of the outcome!

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology

As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.
