bioRxiv: Comparative analysis of MERFISH spatial transcriptomics with bulk and single-cell RNA sequencing
We conclude that compared to scRNA-seq, MERFISH provides a quantitatively comparable method for measuring single-cell gene expression, and that efficient gene panel design allows for robust identification of cell types with intact spatial information without the need for computational integration with scRNA-seq reference atlases.

Nature: Early prediction of preeclampsia in pregnancy with cell-free RNA
e find that changes in cfRNA gene expression between normotensive and preeclamptic mothers are marked and stable early in gestation, well before the onset of symptoms. These changes are enriched for genes specific to neuromuscular, endothelial and immune cell types and tissues that reflect key aspects of preeclampsia physiology6,7,8,9, suggest new hypotheses for disease progression and correlate with maternal organ health.

Cell Reports: Sexual and asexual development: two distinct programs producing the same tunicate.
Our findings demonstrate that convergent morphology need not imply convergent molecular mechanisms but that it showcases the importance that tissue-specific stem cells and transcription factors play in producing the same mature body through different pathways.

PNAS: Hydrogenotrophic methanogenesis in archaeal phylum Verstraetearchaeota reveals the shared ancestry of all methanogens
We discovered hydrogenotrophic methanogenesis in a thermophilic order of the Verstraetearchaeota, a noneuryarchaeote. The Verstraetearchaeota, hitherto known as methylotrophs, unify the origins of methanogenesis and shed light on how organisms can evolve to adapt from hydrogenotrophic to methylotrophic methane metabolism.

Nature: Complex mammalian-like haematopoietic system found in a colonial chordate
Our results show that HSC and myeloid lineage immune cells emerged in a common ancestor of tunicates and vertebrates, and also suggest that haematopoietic bone marrow and the B. schlosseri endostyle niche evolved from a common origin.

Stem Cell Research & Therapy: Identifying deer antler uhrf1 proliferation and s100a10 mineralization genes using comparative RNA-seq
Deer antlers are bony structures that re-grow at very high rates, making them an attractive model for studying rapid bone regeneration. To identify the genes that are involved in this fast pace of bone growth, an in vitro RNA-seq model that paralleled the sharp differences in bone growth between deer antlers and humans was established.
