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

Macron s'inspire de Groland au premier degré en fait.

Cet extrait vient de Groland. Mais quand tu compares avec la réalité, tu ne vois presque plus de différence sur ces histoires de remaniement et de nouveau gouvernement.

Today was a great day for Charline Pasquier, who successfully defended her PhD thesis in front of the jury composed of @annemarthe.bsky.social @ericci-aeruginosa.bsky.social, Stefania Millevoi and Jean-Luc Imler. Congratulations to her for a brilliant defense! 🍾

Phages, viruses that infect bacteria, could help fight antibiotic resistance, but phage–host interactions are not yet sufficiently understood. Researchers from #HIRI, JMU & HZI now successfully interfered with phage reproduction using ASOs.

Our work on the function of miR-51/miR-100 is out! miR-100 is widely conserved across eumetazoans but its function has been mysterious. Emilio Santillán found in worms it regulates signaling and extracellular matrix genes, some of which seem to be conserved targets! www.science.org/doi/10.1126/...
An ancient and essential miRNA family controls cellular interaction pathways in C. elegans
A microRNA that arose at the origin of eumetazoans regulates cell adhesion and signaling in C. elegans through conserved targets.

#InterferonPower! Thrilled for our latest work @cp-cell.bsky.social! With @danielboehmer.bsky.social, we dug into tons of papers & created what we hope will be a go-to resource for immunologists & non-immunologist about type I, II, III (& IV😉) #interferons!

I've seen this on Bluesky and had to try it myself. The image below was the response to the prompt: "Show me a diagram of the US presidents since Herbert Hoover, with their names and years in office under their photos" Bravo, OpenAI, bravo.
A very mistaken list of the last 12 presidents of the United States and their years in office produced by the Ph.D level scholar known as ChatGPT-5. Includes John F. Katwady, president 1991-1968; George W. bush, president 220Z-1999), and Bill Christen, president 1999-2001
