Really cool work! It's interesting to see the difference in unsupervised cell-type separation between the mRNAs and proteins in Fig 1B. I was surprised to see how "low" the diagonal correlations in Fig 1F were (based on the r, not seeing the p-values, although you do state they're significant).

Here’s a bunch of shows happening in Pittsburgh in October! I make these every month. They are in no way comprehensive so I encourage you to keep a look out for more or make your own. Save this to your phone, print it out and hang it somewhere in public, share with your friends!

As a researcher working remotely, I miss having these types of chats to break up the day. Zoom-based "tea times" can be good, but they don't quite offer the same vibe.

... into thinking it was a realistic issue. Anyway, the memory that I argued to a room of young scientists that AI's are going to pose existential risks is a bit cringe-inducing now. Especially since I went over my allotted time.

The presentation was fine, and I don't think the book is *that* off-base, especially for when it was written in 2014. It was predicated on a theoretical AI with true (if simulated) desires/goals, and "aligning" those with our own. Kind of neat philosophy, although I was possibly duped by podcasts

Embarrassing story: when I was a research fellow at the NIH, someone put together a presentation practice group, where us young scientists could get experience giving presentations on casual/science-adjacent topics. I did mine on AI-risk, based on Superintelligence by Nick Bostrom

🧪Today, the PsychAD Consortium published EIGHT papers across Nature journals detailing their efforts to create the largest map of the human prefrontal cortex. It's hard to overstate the amount of work here, nor the absolute treasure trove this team has created for researchers.

Landmark map of human brain’s gene activity holds clues to Alzheimer’s disease and more
The atlas of gene expression in the prefrontal cortex was created using samples from almost 1,500 donors of all ages — from infants to centenarians.

Noncoding transcription controls the developmental dynamics of long-range gene regulation
The genomic regions regulating gene expression are often themselves transcribed into a variety of noncoding RNAs (ncRNAs). However, the regulatory roles of this noncoding transcription remain largely unknown. By using live imaging, we reveal that the ...

I like that Coda rebranded to superhuman docs because it's both longer to type and typing the "docs" prefix makes it collide with all my recently visited google docs. Oh wait, those are both bad things!

Hello, human geneticist here. There is no scientific basis for attempts to define people in terms of “good” or “bad” genes - these are discredited views in service of racist ideologies. For consensus & concerns of experts in our field, see e.g. this 2020 statement from @geneticssociety.bsky.social:
Statement from the American Society of Human Genetics in 2020, countering the myth of "good genes". It reads as follows:
"Genetics demonstrates that humans cannot be divided into biologically distinct subcategories or races, and any efforts to claim the superiority of humans based on any genetic ancestry have no scientific evidence. Moreover, it is inaccurate to claim genetics as the determinative factor in human strengths or outcomes when education, environment, wealth, and health care access are often more potent factors. There is no factual basis for attempts to define communities or regions of people with "good" or "bad" genes and a century of science has debunked such claims, which can feed discredited views and racist ideologies. Unchecked, unethical application of false genetic "theories" have resulted in past atrocities from forced sterilizations to the Holocaust and can still fuel unethical social policies worldwide today. Over the decades, our field also has reflected on its own role in such now-condemned ideas, and we speak out vocally as a community and as individuals to combat their resurgence.
We must protect and advance the ethical use of genetics and genomics knowledge for the profound good it can realize, including better, more precise healthcare that leverages what we are discovering about human genetic commonality and diversity. The human genetics community dedicates itself to this goal each day, and today we are improving and saving hundreds of thousands of lives. As the ASHG community focuses on realizing the benefits of human genetics and genomics research for people everywhere, we also urge societal attention to address profound educational, economic and health inequalities that fuel differences in human experience and well-being. By pursuing all of these activities, humans can celebrate our common heritage as one people, embrace and fully tap our valued diversity, and help achieve optimal life outcomes for all."
