Termination of the integrated stress response Stress responses enable cells to detect, adapt to, and survive challenges. The benefit of these signaling pathways depends on their reversibility. The integrated stress response (ISR) is elicited by p...

Answer to a key and longstanding question;
How does the integrated stress response terminate?

"Here, we discover that giant DNA viruses encode a distinct and functional IF4F translation-initiation complex to drive protein synthesis, thereby blurring the line between cellular and acellular biology"

RNA splicing generates a functionally specialized Rep protein isoform in geminiviruses โ€” enabling timely control of the viral cycle. Strikingly, similar strategies might have evolved in DNA viruses infecting different kingdoms: www.biorxiv.org/content/10.6... Spearheaded by @delphinem-p.bsky.social!

Just in time for Christmas a new paper in @plantspeopleplanet.bsky.social by @joannakacprzyk.bsky.social and myself.
We asked 421 plant scientists why they study plants!
Check it out and also check @plantmemories.bsky.social where we post lovely survey responses.

Timing of transcription controls the selective translation of newly synthesized mRNAs during acute environmental stress Under stress, cells adapt their gene expression programs through changes in transcription and translation. It is unclear how cells determine which mRNAs are translated or repressed. Zedan et al. show that the timing of mRNA production alone determines the selectivity of translation, thereby coupling the processes of transcription and translation.

This is not a screen from a video game. Nestled below the tree-line, the small mountain church does look like it might be hiding from Moon though. In the well-composed telephoto snapshot, taken on November 23, the church walls are partly reflecting light from terrestrial flood lights. Of course, the Moon is reflecting light from the Sun. At any given time the Sun illuminates fully half of the Moon's surface, also known as the lunar dayside, but on that night only a sliver of its sunlit surface was visible. About three days after New Moon, the Moon was in a waxing crescent phase. The single exposure was captured shortly after sunset in skies near Danta di Cadore, northern Italy, planet Earth.
