Yesterday I posted a piece about @OrchidInc's polygenic embryo selection. I thought, based on a press release I read, that they were the first company to undertake polygenic embryo selection. 1/ liorpachter.wordpress.com/2021/04/12/the…
The press release started w/ "Orchid, the first preconception system to quantify how a couple's genetics impacts their future child's health, today announced a $4.5M seed round..". It went on to describe the company's polygenic embryo selection product. 2/ prnewswire.com/news-releases/…
I naïvely assumed that Orchid is the first company to embark on polygenic embryo selection, but TIL that is not the case. In fact, more than two years ago, an article in @TheEconomist discussed myome.
That's five @Stanford profs I'm aware of currently advising or assisting companies engaging in polygenic embryo selection (w/ @JanLiphardt & @cdbustamante for @OrchidInc). Super disappointing that they would engage in this scientifically bankrupt & morally repugnant enterprise.6/
I highlight @stanford because while this has been going on, @MLevitt_NP2013, Ioannidis, Atlas, and Bhattacharya, also all @Stanford, having been engaged in scientifically bankrupt and morally repugnant #covid19 denial. As a separate matter, Palo Alto, we have a problem. 7/
In terms of myome and Orchid, I really hope the genetics community comes together to send a strong message to the public about why PES is a horrible idea. 8/

In September I wrote a blog post reciting several false #covid19 claims and predictions made by Levitt over the course of the pandemic. That is not an "ad hominem attack". I reported Levitt's claims (with references). liorpachter.wordpress.com/2020/09/21/the… 2/14
Levitt, for his part, has responded to criticism of his failed predictions with non-sequiturs about attacks on free speech.
There is a lot of focus on the importance of reproducible science for facilitating replication of published research. That's all good, but reproducible science has another benefit: when adopted by a group it is an incredible accelerant for research *in that group*. 2/
Consider the paper we wrote on whole animal multiplexed #scRNAseq. The @GoogleColab notebooks Tara Chari wrote for the analyses were a monumental effort, but she did not start from scratch. 3/
The design is simple and elegant. A single motor drives the shaft of the tube rack, which is coupled to the dispenser arm via a spiral track. This ensures both rotate in tandem. 2/
The device is easy to 3D print and build, and can be assembled from off-the-shelf parts in less than an hour for $67.02. This low cost, and the straightforward assembly, is possible thanks to the design around a single motor. Amazing work by @annekylosaurus & @sinabooeshaghi. 3/
Universal Health Services @UHS_Inc is the largest facility-based behavioral health provider in the country. Its mission statement includes "To provide..healthcare services that..INVESTORS seek for long-term returns."
We show #scRNAseq can be used for "reverse genomics" to conduct low-cost *experiments*. Instead of sequence first ask questions later, we ask questions first & then sequence. We illustrate the approach w/ a starvation experiment using the emerging model Clytia hemisphaerica. 2/
We performed multiplexed #scRNAseq using the ClickTag approach developed in our lab by @JaseGehring (w/@sisichen, Matt Thomson, Jeff Park). The chemical multiplexing can be used on any tissue/animal and facilitates experiments with little batch effect. 3/ nature.com/articles/s4158…
