✅ Uno studio condotto su 3.000 incisioni paleolitiche rivela sorprendenti sequenze di segni, la cui complessità è paragonabile alla proto-cuneiforme mesopotamica. Lo studio è pubblicato sulla rivista scientifica PNAS

How can tiny amounts of gas produced by cosmic rays inside grains of sand give clues about Australia’s ancient landscapes?

Researchers at our Uni, #Curtin & #Köln demonstrated a new method to reconstruct how ancient landscapes eroded and sediments moved across continents millions of years ago. Find out about the cosmic clock in tiny crystals: https://www.uni-goettingen.de/en/3240.html?id=8063

By combining high-resolution electrostatic mapping with molecular dynamics simulations, we investigated the behavior of these surface-trapped ionic charges. We found that they spread across the surface with remarkable mobility. Their two-dimensional diffusion exceeds that of ions in bulk water, with the limiting factor being the friction between the ionic solvation shell and the solid.

How is climate change going to affect Arctic shorelines? A new #PNAS #paper involving #MPI_scientist David Nielsen finds that, by 2100, there may be:
🌊 unprecedented land loss pushing the Alaskan coastline further inland than at any point in the last 100,000 years 🌊
🐟 potentially 8–11 times more carbon released than from coastal erosion alone, affecting marine ecosystems 🐟

'Herein, we report that ZIKV encodes a unique DNA-binding protein to regulate host gene transcription in the nucleus. We found that ZIKV NS5, the viral RNA polymerase, associates tightly with host chromatin DNA through its methyltransferase domain and this interaction could be specifically blocked by GTP. Further study showed that expression of ZIKV NS5 in human NPCs markedly suppressed the transcription of its target genes, especially the genes involved in neurogenesis.'
