Antisémitisme et critique d’Israël : à l’Assemblée, la mobilisation monte d’un cran contre la loi Yadan Plus d’un demi-million de Français ont signé la pétition appelant les députés à voter contre la proposition de loi sur les « formes renouvelées de l’antisémitisme », portée par la macroniste Caroline Yadan. À gauche, on espère que la mobilisation citoyenne influencera les élus lors de l’examen du texte la semaine prochaine.

Max Fels @mfels.bsky.social from our lab discovers giant DNA viruses that infect amoeba encode eIF4E and the entire suite of 4F complex proteins to control mRNA translation, including beautiful crystal structures of viral 4E bound to modified mRNA 5' caps:

#PressRelease🗞️ A specific molecular mechanism has been identified as the cause of the most frequent genetic forms of amyotrophic lateral sclerosis (ALS, also known as Charcot’s disease) and frontotemporal dementia (FTD).

Pre-assembly of biomolecular condensate seeds drives RSV replication Nature - Viral ribonucleoprotein–viral protein networks form pre-replication centres that nucleate viral factories and drive respiratory syncytial virus replication.

Now out in Nature! We visualize infection of the RNA virus RSV in real-time with single-vRNP resolution to understand how RSV establishes viral factories, biomolecular condensates that act as sites of viral replication. A huge collaborative effort led by Dhanushika Ratnayake!

Au terme d'une analyse totalement déconnectée de la réalité dont les crânes d'oeuf de Bercy ont le secret, Le gouvernement en déduit qu'il peut récupérer 1,4 milliards d'euros (sur 2,5) sur le dos des universités et de l'ANR principalement.

#RNAi is an ancestral #antiviral system that degrades viral RNA, but what about in #cnidarians? @yehumoran.bsky.social &co show that #Nematostella has an siRNA-mediated antiviral response that lacks 2ary amplification & functions as a short-term antiviral mechanism @plosbiology.org 🧪 plos.io/3N192OD

Our latest paper on bat Dicer! 🦇 we show that Dicer antiviral RNAi activity is context-dependent also in bats 👩‍🔬 Specifically in Myotis myotis nasal epithelial cells, Dicer relocalizes to sites of viral replication upon alphavirus infection, which correlates with a proviral activity of Dicer 🦠

Bat Dicer antiviral role and subcellular localization differ upon alphavirus infection in two distinct species Author summary Bats are important to study as they are reservoirs for many viruses that can cause severe disease in humans. Notably, bats often show no clinical symptoms when infected with these virus...

Avian-origin influenza A viruses tolerate elevated pyrexic temperatures in mammals Host body temperature can define a virus’s replicative profile—influenza A viruses (IAVs) adapted to 40° to 42°C in birds are less temperature sensitive in vitro compared with human isolates adapted t...

How does fever work?

Our new Science paper shows how elevated body temperature can protect against severe influenza and that avian-origin viruses escape this defence.

This is likely one reason why bird flus and some pandemic influenzas can be so severe.🧵

BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 (thread 👇)

Are bats tolerant of all viruses? With a comparative -omics approach, we show that Egyptian fruit bat cells show both antiviral and pro-inflammatory immune responses to infection with Zika virus while our Jamaican fruit bat cells are not susceptible.

Ce mépris venu de l’Élysée La reconduction de Sébastien Lecornu à Matignon, cinq jours après sa démission, est stupéfiante parce qu’insensée. Le président de la République a définitivement renoncé à aligner ses décisions sur les aspirations populaires. Seule compte à présent la conservation du pouvoir.

BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

I researched every attempt to stop fascism in history. The success rate is 0%. Once they win elections, it's already too late.

This was an interesting read.
