Our new preprint is out: we solved the structures of HIV-1 matrix (MA) from intact virions by SPA. The structure led us to a surprising discovery resolving a long mystery in HIV-1 biology – peptide SP2 regulates the maturation of the HIV-1 matrix. 🧵1/x tinyurl.com/c7szhtfa

Organism-level synthetic life is closer than ever

Should we rely on journal impact factors in #systematics and #taxonomy? 🤔 Mycologist Henrik Nilsson explores this question in a Pensoft guest blog post: 🔗 blog.pensoft.net/2024/11/22/sho…

Opinions on Blue Sky? It will be the same as mastodon? Worth trying?

There is no Spanish octopus so far, all of it comes from abroad, we need to think about it

Beautiful animation of metabolic flux in the mitochondrial Kreb (TCA) cycle The three "CO2" coming off the cycle is how you lose weight: carbon from your material body coming off as gas you end up breathing out By Janet Iwasa

This is very promising 👉 AI co-scientist, a multi-agent AI system built with Gemini 2.0 as a virtual scientific collaborator to help scientists generate novel hypotheses and research proposals. AI as a tool again, closer to AGI too research.google/blog/accelerat…

This is Stemonitis, a slime mold, forming delicate, feather-like sporangia to release its spores. Before this, it lived as a single-celled organism, flowing through the forest floor, seeking bacteria and decaying matter.

Potential biosignature on Mars: confirmed. ✔️ After a year of scientific review, we are more sure than ever that our Mars Perseverance's 'Sapphire Canyon' sample could contain signs of ancient microbial life. Learn more about the discovery: go.nasa.gov/46jy4hL

This is huge! A UCLA team managed to build an optical generative model that runs on light instead of GPUs. In their demo, a shallow encoder maps noise into phase patterns, which a free-space optical decoder then transforms into images—digits, fashion, butterflies, faces, even

Our immune system is an evolutionary masterpiece. Every day it protects us from the thousands of different viruses, bacteria and other microbes that attempt to invade our bodies. Without a functioning immune system, we would not survive. One of the immune system’s marvels is its
