Amos was not only a giant of bioinformatics and biocuration, but one of the nicest people I've met in academia. His support and advice were invaluable when we were establishing @bgee.org, and I will always remember how warmly he welcomed us to @sib.swiss when I arrived in Switzerland 20 years ago.

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen.

https://link.springer.com/article/10.1007/s00239-025-10277-1 Conceptual overview of hierarchical orthologous groups. An example of one HOG, or gene family. A Species tree with four taxa: plant (green), fish (blue), human (orange), and mouse (yellow), each with one or more genes. B The implied gene tree, dubbed “HOG tree,” and inferred nested HOG composition. Duplication nodes (red) can be deduced based on the species tree topology and clusters of homologous genes at each level. Ancestral genes from which the HOGs descended are shown in gray. C HOGs returned at different taxonomic levels. Consider a gene family that was present in the last eukaryotic common ancestor (LECA). At this level, a single HOG encompasses all genes descending from that ancestral gene. At the Vertebrata level, this gene underwent duplication, leading to two distinct copies, i.e., HOGs. At the Mammalia level, a second duplication further subdivides one of these HOGs, showing how deeper HOGs split into nested subHOGs at more recent levels. The HOG composition implies that a loss event occurred after the mammalian speciation

https://link.springer.com/article/10.1007/s00239-025-10271-7 Overview of the OrthoXML File Format (simplified). A schematic representation of an OrthoXML file, a standardized XML-based format for representing orthology data. OrthoXML follows a hierarchical structure where elements are enclosed within opening < tag > and closing </tag > tags. < orthoXML > is the root element enclosing other elements. The < species > element contains information about genes. An OrthoXML file can include a < taxonomy > element, which specifies the species tree used to generate the file. Additionally, the < groups > element encapsulates the orthology and paralogy relationships among genes

Great work by Nicola De Maio and Nick Goldman - not just scaleable to "pandemic scale" trees but - if I have got this right - arguably more valid than traditional column based bootstrap in the context of very tight evolution.

Yes - isometric scaling as a way to understand the benefits and costs of being small versus large. Haldane's Harpers article from 1926 is an amazing example of popular science writing.

Can an AI tool help us better understand the origins of cancer?

Researchers from EMBL's Korbel Group have developed a new AI method – MAGIC – which, through a game of molecular laser tag, is shedding light on how chromosomal abnormalities form in cells.

Unlocking the regulatory code of RNA: launching the Human RNome Project | Genome Biology | Full Text The human RNome, the complete set of RNA molecules in human cells, arises through complex processing and includes diverse molecular species. While research traditionally focuses on four canonical nucleotide residues, the RNome, encompassing over 180 distinct modifications across organisms, with at least 50 in humans, is increasingly recognized. These modifications play critical roles in regulating RNA structure, stability, and function, yet the rules linking their precise locations to biological outcomes remain poorly defined. The Human RNome Project aims to map all RNA modifications, build essential resources, and harness new technologies to transform RNA biology, therapeutic development, agriculture, and even data storage.

I am genuinely impressed by large language models - they can absorb disparate components of text into some consolidated view, they can produce extremely good language and - with the right model - translate pretty well between languages and they are an excellent text based UI for humans to use.
