A study in Nature Communications finds a decrease in severe hail across Europe under a high emissions scenario. However, very large hail remains a threat, particularly due to the emergence of tropical-like thunderstorms around the Mediterranean coasts. go.nature.com/46vFhg0 🧪
This is figure 5, which shows warm-type thunderstorms.

The liver #transcriptome is highly sensitive to metabolic cues. By characterizing nuclear protein #OGlcNAcylation in mouse #liver during the day, @joanna-chiu.bsky.social &co show how shifts in a nutrient-sensitive #PTM may shape transcriptional regulation @plosbiology.org 🧪 plos.io/3KuS7m1
Model describing how daily rhythmic O-GlcNAc proteome integrates environmental and metabolic signals to regulate transcriptomic and physiological rhythms. Environmental cues signaling through the molecular clock and metabolic cues from feeding–fasting cycles regulate daily rhythms in the O-GlcNAc proteome. Rhythmic O-GlcNAcylation can directly shape daily rhythmicity in transcriptome and physiology. In addition, rhythmic O-GlcNAcylation can also interact with rhythmic phosphorylation. Different forms of crosstalk between O-GlcNAc proteome and phosphoproteome are shown in the middle box. The red solid arrows indicate the regulations described in this study, while the dashed arrow indicates regulations discovered by previous studies. Figure created using BioRender.com.

How do we balance innate responses & adaptive learning when reacting to threats? @tjryan.bsky.social &co show that repeated exposure to looming stimuli reduces innate defensive responses via #hippocampal modulation, revealing a vCA1 engram needed for learned #fear @plosbiology.org 🧪 plos.io/4pNSnNp
Patterns of c-Fos expression in the SC, PAG, and HPC reveal a loss of activity in the SC and PAG following extinction-updating but persistent activity of the vCA1. Top left: Engram labeling strategy. Bottom: TRAP2xAi32 mice underwent one of three types of behavioral paradigms; re-exposure (n = 6 mice) vs. no re-exposure (n = 6 mice), extinction (n = 7 mice) vs. innate (n = 8 mice), or updating (n = 11 mice) vs. innate (n = 8 mice). Mice were injected with 4-OHT to transiently induce c-Fos dependent EYFP upon first exposure to the looming stimulus, and later perfused 60 min following stimulus presentation at the end of the behavioral paradigm. Tolp right: Example histology from the SC, with an EYFP+c-Fos+ cell highlighted by the white arrow.
