Never mistreat readers. Thanks, @governor.ca.gov. #COP30 @milkeninstitute.org
We’re in Brazil — one of the world’s great democracies, one of our biggest trading partners — and not a single person from the Trump Administration showed up.

That’s shameful.

A decisão dos senadores de aumentar os incentivos à usinas movidas a carvão, acontece às vésperas do início da Conferência do Clima da ONU (COP30), em Belém, no Pará. Entenda:
A toque de caixa: Senado aprova em 5 minutos lei que beneficia termelétricas a carvão
Em votação a jato e às vésperas da COP30, políticos aprovaram texto que dá mais benefícios para termelétricas a carvão

Dear @harryspoelstra.bsky.social sharing here too, so many professionals and students need to be aware that multiple vaccines on the same day are not recommendable for many cases. Co-adm of flu & Covid-19 shots needs a time window to immune resilience. @minsaude.bsky.social @cienciaufpr.bsky.social
IL-6 and IL-8 elevations after co-administration of COVID-19 and influenza vaccines are associated with lower anti-spike IgG titers at three and six months post-vaccination
The early innate immune response to vaccination plays a crucial role in shaping adaptive immunity and long-term protection. In this study, we investig…

It’s out! Over the past few months, my colleagues and I at @unbreaking.org have been working to document the political, legal, and economic maneuvers the US administration has used to undermine medical research funding. We hope you’ll find it useful!

Great updates to virus maturation, it reminds the value of cross-reactivity comparisons among vectors, besides reservoirs in virology back to epidemiological conditions of non-primary transmission routes, even to dengue-to-human zoonotic jumps.

FYI @franceculture.fr.
Oct 29th in France: any nonconsensual sexual act legally constitutes sexual assault: violence, constraint, threat or surprise, there is no consent.
Don't support people who force relationships to financially abuse of victims. Not a fan of gross psychologists and psychopaths.
Husamettin Dogan appealed his conviction for the rape of Gisèle Pelicot. His sentence was increased by one year—“a recognition that denial itself is a form of cruelty,” writes @diane2v.bsky.social.
Gisèle Pelicot’s pedagogy of justice
A retrial in the landmark French abuse case is a lesson in how rape survivors are retraumatised in court

Gastropoda mutations in active delivery among cells have intact mtDNA, while regulated membrane-dependent transfers of mitochondria-like organelles. Aging-adaptation to cell differentiation, an environmental consequence way more than regulation of deliveries.
Are mitochondrial DNA mutations under purifying selection in somatic tissues? https://www.biorxiv.org/content/10.1101/2025.10.26.684677v1
