Our ancestors emerged on a primitive Earth that lacked oxygen. @ishahjain, @AyushDMidha, and team found a surprising way that we still use their coping strategies today. https://t.co/1oIoziHOXO 1.4K views · 4 likes · 4 reposts · 2 replies Open on X →

Science Fellow @zhou_jingtian builds single-cell and computational frameworks to probe the 3D genome. His work tells us more about how the epigenome and transcriptome interact to shape cell state and complex disease: https://t.co/r0GEIDg4gz 4.8K views · 20 likes · 2 reposts · 1 replies Open on X →

We share our rationale and evaluation approach for the competition in a commentary published today in @CellCellPress. Our goal is for this event to build a new community of machine learning researchers, computational biologists, and experimentalists. https://t.co/WwK3DQWcDI 12.8K views · 25 likes · 5 reposts · 3 replies Open on X →

@arcinstitute A particularly important shift is the focus on generalization across unseen biological contexts. In biological simulation, prediction is only part of the problem. Equally important is knowing when a new state is outside the model’s support — and when the model shoul 6 views · 0 likes · 0 reposts · 0 replies Open on X →

Competitors will receive a validation dataset with 3 cell lines, each containing the non-targeting control profiles plus the CRISPRi knockdown gene IDs to predict for 300 perturbations per cell line. A test set with 3 distinct cell lines will be held out until the final phase. ht 1.1K views · 10 likes · 2 reposts · 2 replies Open on X →

We also redesigned the scoring. We're using six complementary metrics, each scaled between the cell context mean and data from a real replicate experiment. The overall score is a single unweighted average over the six metrics and cell contexts. https://t.co/TuVjsA0l1t 1.8K views · 14 likes · 4 reposts · 2 replies Open on X →

Evolution builds genes by recombining domains from existing ones. Innovation Investigator @Roth_Lab and colleagues introduce DESynR, a platform that does this on demand, creating new genes that outperform their natural counterparts in human CAR T cells. https://t.co/GuQwiPSStN 8.3K views · 76 likes · 20 reposts · 2 replies Open on X →

Four years ago, a mystery case led Core Investigator @jvpluv to discover a new diagnosis (ABCD). Today his team published one of the largest clinical surveys of unexplained spinal cord disease to date in @JAMANeuro, finding ABCD in roughly half of patients. https://t.co/IMDAnaMOQ 10.2K views · 46 likes · 10 reposts · 3 replies Open on X →
