HFpEF in animals models are a

Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com

New Article! Spatially resolved in situ profiling of mRNA life cycle at transcriptome scale in intact cells and tissues using STARmap PLUS, RIBOmap and TEMPOmap
Spatially resolved in situ profiling of mRNA life cycle at transcriptome scale in intact cells and tissues using STARmap PLUS, RIBOmap and TEMPOmap
Nature Protocols, Published online: 30 September 2025; doi:10.1038/s41596-025-01248-3This protocol for imaging-based highly multiplexed in situ profiling of the spatial transcriptome uses three methods: antibody-based protein comapping with STARmap PLUS, ribosome-bound mRNA mapping with RIBOmap and spatiotemporal transcriptome mapping with TEMPOmap.

Online Now: Extrachromosomal DNA biogenesis is dependent on DNA looping and religation by YY1-Lig3-PARylation complex Online now:
Extrachromosomal DNA biogenesis is dependent on DNA looping and religation by YY1-Lig3-PARylation complex
Qin et al. show that Lig3 PARylation promotes ecDNA formation, requiring YY1-mediated DNA looping. The Lig3-YY1 complex establishes a PARylation-dependent acidic microenvironment, inducing unstable Z-DNA transition states, which are religated by Lig3, ultimately mediating the biogenesis of ecDNA.

This is why Israel refuses to allow the international press access to Gaza.
Because images like this make it impossible to deny that this is genocide.

We have created a new DNase I- & ATAC-seq peak caller that uses an adaptive background model that controls for copy number variation & aneuploidy. It performs a per-nucleotide test (+FDR correction) and is very fast. Please try it out and give us feedback!
