New preprint! sciMET-cap, where we use hybrid capture to reduce the sequencing burden of scMethylation and show ~6,000 cell preps are possible using a benchtop sequencer! Led by S. Acharya and @oconnellphds with @DrTedPBraun & @L_Rylaarsdam. biorxiv.org/content/10.1101/…

Summary of our latest two papers on GenomeWeb! Thanks for the coverage - we are excited about both of these techniques regarding how they can improve the scale of single-cell epigenomic studies; both led by @oconnellphds! @OHSUSOM #singlecell #epigenetics
OHSU Researchers Push Throughput, Accessibility for Single-Cell Epigenetic Assays. An improved sample prep workflow for single-cell methylation analysis offers the prospect of commercialization, which could be readily taken up in cancer genomics. ow.ly/6NBa104wCnV

Nice article discussing some of the complexities of variants found by @OregonCovidSeq team of scientists. @BenBimber @acadey80 @BenBimber @SallyGrindstaff @oconnellphds @snchry Kayla Carter.
So, we’ve all been hearing about the arrival of these COVID ✨variants✨ Is it time for us to go out and panic? @TheRealDrOLab says no. But it’s a bit complicated, and he very kindly explained the situation to me — check out the story @Oregonian ⬇️⬇️⬇️ oregonlive.com/coronavirus/2…

Replying to @OregonCovidSeq
@OregonCovidSeq has been busy the past ~month w/ 572 new genomes now in @GISAID. +5 complete #VOC #B117. As just reported by @apoorva_nyc, worryingly, one of these #B117 samples also contains the spike #E484K, which is a key mutation in #P1 & #B1351 #VOC 🧵1/10 on these & others

Four years' work, 178 billion sequencing reads, and nearly 5 million cells went into constructing atlases of gene expression and chromatin accessibility in human development, out now.

New preprint! In work led by Ryan Mulqueen, we describe “s3”, a technology that improves the coverage of single-cell assays including s3-ATAC, s3-WGS, and s3-GCC (WGS+HiC)! #singlecell High-content single-cell combinatorial indexing biorxiv.org/content/10.1101/…

Read about latest work from our team sequencing #SARSCoV2 in #Oregon @BenBimber @oconnellphds @acadey80 @PDXdengue @OHSUSOM
Our 3nd released of 155 new #SARSCoV2 genomes to @GISAID w/ metadata and now available in today's @nextstrain release. 149 #Oregon and 6 #SWWA. This brings the number of #Oregon viral genomes available to over 400! @OHSUNews @OHSUSOM #COVID19 xitter.cf/nextstrain/status/1291… 👇1/n

Everyone needs to understand that the decline of SARS-CoV-2 Abs after the peak of infection is normal. This is basic immunology. If our immune system did not contract after viral infections, we would all be walking around with gigantic lymph nodes. SARS-CoV-2 Abs look good!
A new @NEJM report on rapid decay of #SARCoV2 antibodies in people with mild infections nejm.org/doi/full/10.1056/NE… For context of this finding, @DKThomp took it on yesterday nejm.org/doi/full/10.1056/NE… @TheAtlantic and xitter.cf/EricTopol/status/12784…
