Mitigating corrosion by liquid tin could lead to better cooling in fusion reactors      (via sciencedaily.com) 

Researchers have clarified the chemical compatibility between high temperature liquid metal tin (Sn) and reduced activation ferritic martensitic, a candidate structural material for fusion reactors. This discovery has paved the way for the development of a liquid metal tin divertor, which is an advanced heat-removal component of fusion reactors. A device called a divertor is installed in the fusion reactors to maintain the purity of the plasma. For divertors, there has been demand for liquid metals that can withstand extremely large heat loads from high-temperature plasma.

Climate whiplash increased wildfires on California's west coast about 8,000 years ago      (via sciencedaily.com) 

Researchers have been studying the effects of the sudden decrease in global temperatures that occurred about 8,200 years ago, the so-called 8.2-kiloyear event, with the help of mineral deposits present in White Moon Cave in Northern California. New indications show that oscillations between extreme wetness and aridity in California were closely linked with the occurrence of wildfires. The researchers have concluded that such events are likely to become more common in the face of human-induced climate change.

Americans flocking to fire: National migration study      (via sciencedaily.com) 

Americans are leaving many of the U.S. counties hit hardest by hurricanes and heatwaves -- and moving towards dangerous wildfires and warmer temperatures, says one of the largest studies of U.S. migration and natural disasters. These results are concerning, as wildfire and rising temperatures are projected to worsen with climate change. The study was inspired by the increasing number of headlines of record-breaking natural disasters.

How long can exotic nuclei survive at the edge of stability?      (via sciencedaily.com) 

A new study has measured how long it takes for several kinds of exotic nuclei to decay. The paper marks the first experimental result from the Facility for Rare Isotope Beams. It is just a small taste of what's to come at the facility, which will become 400 times more powerful over the coming years. Scientists used the facility to better understand nuclei, the collection of protons and neutrons found at the heart of atoms. Understanding these basic building blocks allows scientists to refine their best models and has applications in medicine, national security, and industry.
