Saiu o Revelando, tá? Ainda não assisti, estreou a pouco Parece a é sobre a ligação de um candidato a presidente da República com grupos de extermínio, que é como deveríamos chamar as milícias Eu acho que Deveria viralizar até virar assunto na Internet Bora galera, curtam, espalhem

Our lab just put out a new preprint! Led by Maria Maltepes, we've been working with @tavisanderson.bsky.social and @alexey-markin.bsky.social to understand how host species impacts the fundamentals of how influenza viruses evolve. TLDR, reassortment and selection rates vary widely across species.

Hey, I wrote a thing about AI in astrophysics ergosphere.blog/posts/the-ma...

The machines are fine. I'm worried about us.
On AI agents, grunt work, and the part of science that isn't replaceable.

We have posted data providing real-time measurement of human neutralizing antibody landscape to seasonal influenza. Data explain spread of subclades K (H3N2) & D.3.1.1 (H1N1), identify subclade K subvariants w reduced neutralization, & can inform choice of strains for next vaccine.

Today @natmedicine.bsky.social published our study showing the older individuals born prior to 1968 have more antibodies that cross-react to #H5N1 relative to younger individuals. If H5N1 causes a pandemic, children will likely be the most susceptible. 1/2 www.nature.com/articles/s41...

Immune history shapes human antibody responses to H5N1 influenza viruses - Nature Medicine
H5N1 strain-specific antibodies are higher in older individuals and correlate more with birth year than with age, suggesting that younger individuals are potentially more likely to benefit from H5N1 v...

Bayesian spatio-temporal modeling to assess the effect of land-use changes on the incidence of Cutaneous Leishmaniasis in the Brazilian Amazon
Cutaneous Leishmaniasis (CL) is a vector-borne disease caused by a protozoan of the genus Leishmania and is considered one of the most important negle…

Seems population immunity should be useful for forecasting flu, right? Using cross-sectional, age-representative neutralizing titers measured in the summer of 2017 in Philly, we find that the clade to which we infer the greatest susceptibility dominated the next season. Even more, we found...

Antibodies are the product of evolution on two timescales: over millions of years in vertebrate populations, and within weeks of infection or vaccination in populations of B cells. We ask how those timescales interact in our paper out in Plos Pathogens 🧵 1/n t.co/vRdGYYQwsU

Germline-encoded specificities and the predictability of the B cell response
Author summary Antibodies arise as B cell receptors encoded by the stochastic recombination of immunoglobulin genes. While those genes evolve over millions of years, the receptors themselves evolve wi...
