Understanding origins of Arizona’s Sunset Crater eruption of 1,000 years ago

Scientists have been working to solve the mysterious root cause of the Sunset Crater eruption and any lessons learned to better understand the threats similar volcanoes may pose around the world today. But as to why it erupted, that has remained a mystery, until now. Recent research shows the importance of carbon dioxide in volcanic eruptions.

Uncovering basic mechanisms of intestinal stem cell self-renewal and differentiation

The gut plays a central role in the regulation of the body’s metabolism and its dysfunction is associated with a variety of diseases, such as obesity, diabetes, colitis and colorectal cancer that affect millions of people worldwide. Targeting endocrine dysfunction by stimulating the formation of specific enteroendocrine cells from intestinal stem cells could be a promising regenerative approach for diabetes therapy. For this, a detailed understanding of the intestinal stem cell lineage and the signals regulating the recruitment of intestinal cell types is critical.

New and rare direct image of a brown dwarf

Exciting times for efficient heavy-atom-free OLEDs

(Osaka University) An international team including researchers from Osaka University has created an OLED material that combines the mechanisms of thermally activated delayed fluorescence and room-temperature phosphorescence. The hybrid emitter contains only abundant elements, making it more cost-effective and sustainable than heavy-atom-containing alternatives. By combining the two mechanisms the researchers demonstrated the most efficient heavy-atom-free RTP-based OLED to date. It is hoped that the findings will lead to more sustainable display technology.

Impacts of climate change on our water and energy systems: it’s complicated

(DOE/Lawrence Berkeley National Laboratory) Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and UC Santa Barbara have developed a science-based analytic framework to evaluate the complex connections between water and energy, and options for adaptations in response to an evolving climate.
