Get excited :) PhyloSpec is coming! A shared standard + modelling language for phylogenetic models. Write a model once, run it across engines like BEAST X, BEAST 2.8 & RevBayes. Easy and reproducible. Built by @tochsner.bsky.social & collaborators (ETH Zürich, Auckland, LMU). phylospec.com

PhyloSpec
A standardized way to describe phylogenetic model components, common assumptions, and best practices in the field of phylogenetics.

Check out our new method for summarising BEAST trees. The CCD0-MAP tree gives much more accurate results than MCC tree. It returns the tree that maximises the product of sampled clade probabilities regardless of whether that tree was sampled. Highly recommend :) journals.plos.org/ploscompbiol...

20%, under $15m, of Marsden funding went to social sciences while just under $60m went to hard sciences. Total govt research funding in year to March 2023 was ~$1.1b (0.29% of GDP). Cutting the humanities out of Marsden is just spite.

My slightly more considered take on the Marsden fund changes is now here. This govt is focused on the impacts of funding — I don’t mind that — but they don’t seem to have thought for a second about the impact of the lack of it. On people; on society; on academic freedom.
theconversation.com
Funding research for economic return sounds good – but that’s not how science really works
The Marsden Fund was set up to support pure research. Diverting half of it to fund applied research undermines New Zealand’s potential to generate ideas that underpin commercial success.

One of the reasons Bluesky is seeing more engagement: other platforms have adopted the behaviour of de-prioritising external links (like, say, to research papers) due to Ad models. See this: bsky.app/profile/alt... Here links can be freely shared without being drowned out or de-emphasized

There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research. A Place of Joy.

My experience (in phylogenetics, not deep learning) is almost the opposite. When I ask colleagues I know well to look at something, most are polite and encouraging but not *all that critical or useful*. But when I get peer reviews back, they are _almost_ always critical, constructive, and useful.

In a new preprint led by @TheNikhilMilind, we explored a fascinating paradox: For many traits the number of duplications or loss-of-function (LoF) mutations is correlated with phenotype. Curiously, for most traits, the AVERAGE direction of LoFs and Dups is the SAME. Why?

Have ideas about how AI/deep-learning can augment Bayesian model-based (phylogenetic) inference in scientific software like BEAST2? I would love to hear from you. We are embarking on some exploratory work in this direction and there is a lot to learn :)
