Accelerated discovery research unveils 21 novel materials for advanced organic solid-state laser technology
Organic solid-state lasers (OSLs) hold immense promise for a wide range of applications due to their flexibility, color tunability, and efficiency. However, they are difficult to make, and with over 150,000 possible experiments required to conduct to.....»»
Utilizing scanning SQUID microscopy to investigate local magnetic response of Bi2212
Phase transitions in different states of matter, such as the condensation of gases into liquids or the transition from a normal metal to a superconducting state, can be described using Ginzburg-Landau symmetry-breaking theory. However, such a theory.....»»
Experts say coral reef bleaching near record level globally because of "crazy" ocean heat
Ocean temperatures that have gone "crazy haywire" hot, especially in the Atlantic, are close to making the current global coral bleaching event the worst in history. It's so bad that scientists are hoping for a few hurricanes to cool things off......»»
U.S. Supreme Court backs consumer finance watchdog agency"s funding mechanism
Many conservatives and their Republican allies have portrayed the CFPB as part of an overbearing "administrative state," the network of agencies responsible for the array of federal regulations affecting businesses and individuals......»»

The preliminary results of a clinical trial of using heat exposure to combat depression are in—and are fueling cautious optimism that sauna practice could become an accepted treatment......»»
Scientists use generative AI to answer complex questions in physics
When water freezes, it transitions from a liquid phase to a solid phase, resulting in a drastic change in properties like density and volume. Phase transitions in water are so common most of us probably don't even think about them, but phase transiti.....»»
Data-driven model rapidly predicts dehydrogenation barriers in solid-state materials
Researchers have developed a data-driven model to predict the dehydrogenation barriers of magnesium hydride (MgH2), a promising material for solid-state hydrogen storage. This advancement holds significant potential for enhancing hydrogen storage tec.....»»
Five things to know about how NASA"s tiny twin polar satellites will study the Arctic and Antarctic
Twin shoebox-size climate satellites will soon be studying two of the most remote regions on Earth: the Arctic and Antarctic. The NASA mission will measure the amount of heat the planet emits into space from these polar regions—information that's k.....»»
Temperature, time and blueberry wine: Researchers examine fermentation"s effects on health-promoting compounds
Nutrient-rich blueberries—a common breakfast smoothie ingredient—can also create wine. But does the heat and time required to ferment this mighty berry strip out any of those potential health-promoting compounds? Researchers in ACS Food Science &.....»»
From roots to resilience: Investigating the vital role of microbes in coastal plant health
Georgia's saltwater marshes—living where the land meets the ocean—stretch along the state's entire 100-mile coastline. These rich ecosystems are largely dominated by just one plant: grass......»»
Research investigates structural evolution and high-temperature sensing performance of polymer-derived SiAlBCN ceramics
