Titanite-bearing calc-silicate rocks constrain timing, duration and magnitude of metamorphic CO2 degassing in the Himalayan belt [PDF]
The pressure, temperature, and timing (PTt) conditions at which CO2 was produced during the Himalayan prograde metamorphism have been constrained, focusing on the most abundant calcsilicate rock type in the Himalaya. A detailed petrological modeling of a clinopyroxene, scapolite, Kfeldspar, plagioclase, quartz, calcite calcsilicate rock allowed the ...

Abstract Background Radiotherapy (RT) is a key treatment modality in cancer therapy, utilizing high‐energy radiation to directly kill tumor cells. Recent research has increasingly highlighted RT's potential to indirectly enhance antitumor immunity. However, this immune activation alone often fails to generate sustained systemic antitumor responses.

Without catalyst! A non‐enzymatic, spontaneous route to the formation of short, mixed‐sequence RNA strands from 2′,3′‐cyclic ribonucleotides is shown. The reaction occurs by drying at the air–water interfaces. Abstract For the emergence of life, the abiotic synthesis of RNA from its monomers is a central step.
