The 2025 Ig Nobel-winning research was as wacky as ever. But wars, visa restrictions, Trump's border and research policies, and even an all-too-frequent airplane incident kept nearly half the winning teams from traveling to Boston @science.org www.science.org/content/arti...
The Ig Nobels are science’s most lighthearted event. This year is ‘not typical’
Amid Trump research cuts, visa restrictions, and international conflicts, some winners sit out the celebration of whimsical science

Cytosolic viral RNA is detected by #antiviral #PatternRecognition receptors like RIG-I. This study shows that #Mediator subunit MED23 limits RIG-I expression via FOXO3, dampening #InnateImmunity & highlighting MED23 as a potential therapeutic target @plosbiology.org 🧪 plos.io/457VwOe
Schematic showing that Med23 inhibits the antiviral IFN-I response by negatively regulating RIG-I. Med23 interacts with Foxo3 to transcriptionally repress RIG-I, thereby inhibiting the RNA virus-induced phosphorylation of TBK1 and IRF3, suppressing antiviral innate immune response, and promoting virus replication.

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬?

In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments!

👇 Check out all the details in Paula’s thread!

Hint: 🐇 (most of the time)

Mechanism of cotranslational protein N-myristoylation in human cells
Mechanism of cotranslational protein N-myristoylation in human cells
In structure-function studies, Gamerdinger and Echeverria et al. uncover the cotranslational mechanism of N-myristoyltransferases (NMTs), essential enzymes that attach a lipid anchor to newborn proteins. They show that NMT activity is orchestrated by a key regulator at the ribosomal tunnel exit, the nascent polypeptide-associated complex (NAC).

The role of mobile DNA elements in the dynamics of plant genome plasticity - Emmerson & Catoni

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪 @robynemm.bsky.social‬
Fig. 3.Extrachromosomal DNA (ecDNA) in plant cells. Both circular (eccDNA, black circles) and linear (eclDNA, black lines) ecDNA of mobile elements can be found in plant cells. These molecules can enter the cell as viral forms (marked with 1) or be generated by endogenous DNA copies integrated into the genome, directly (2) or by reverse transcription into virus-like particles, starting from transcribed RNA molecules (3). Independently propagated eccDNA is also found associated with organelles (4). The ecDNA can leave the cell using viral carrier systems, in the presence of infections.
