When you send a sample for sequencing, I’m actually one of the people who sorts through the reads. We just put them in a big pile on the table and all gather round. I like long reads because they’re easier to pick up with my hands.

We love to fetishize "top" researchers and give them special big pots of money. But we get far more science by spreading money among all researchers (closer to the NSERC DG model). This old post is magically relevant again... scientistseessquirrel.wordpress.com/2015/05/12/w...

Why does anyone use the Wilcoxon test for anything?
It's not even transitive. It's sensitive to things one most likely is not looking for (changes in distribution shape) and relatively insensitive to what one usually is looking for (change in location).

This is very exciting! I still haven’t found a super clean solution for integrating Bedtools and Python, so this functionality in Bedder is very interesting and I’m looking forward to trying it out.
We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen.

Dismantling the Institutional Review Board (IRB), that oversees all human subjects research, is bad. Really bad.
The entire HR department at the CDC is gone. Everyone at the IRB, which makes sure studies are conducted ethically and rigorously, and the ethics office, which oversee conflicts of interest for CDC leaders and advisory committee members, were also let go.

I wonder if we could leverage ORCID to create Bluesky verification records for researchers. It would allow for scientists to become validated by their own body of work and is something already used in the community.
