In UCLA-led study, perovskite-based devices benefit from the strong bond between lead and the same chemical found in coffee and tea
Scientists at the California NanoSystems Institute at UCLA have found that caffeine improves the stability of materials under heat – a property known as thermal stability — of perovskite solar cells, which could someday replace traditional silicon-based solar cells. (more…)
Zuwendung zu problematischen Inhalten begünstigt Suizidgedanken, Hoffnungslosigkeit und selbstverletzendes Verhalten
Bildliche Darstellungen von Suizid und Selbstverletzung finden sich auf Instagram, einer Social Media Plattform, die vor allem bei jungen Menschen populär ist. Wissenschaftliche Untersuchungen dazu kamen zum Schluss, dass Selbstverletzung und Suizid präsent sind und teilweise äußerst explizit dargestellt werden. (more…)
As the oceans warm in response to climate change, fishing boats in the Mid-Atlantic that focus on only one or two species of fish are traveling more than 250 miles farther north than they did 20 years ago, while others catching a wide diversity of species have not changed fishing location, reported Talia Young, a postdoctoral research associate in ecology and evolutionary biology at Princeton.

Researchers have combined two separate computer models to identify areas at highest risk for outbreaks of lumpy skin disease virus (LSDV) in cattle. The models could help officials determine where to send resources ahead of outbreaks and serve as a potential early warning system for cattle farmers in affected areas. (more…)
Discarded mattresses have long been a thorn in the side of garbage collectors; over 300 mattresses are thrown out every day to make their way to landfills. This is a shame, because while old mattresses take up hundreds of thousands of square miles in landfills each year, many of their parts including the metal springs, fabric, and wood can be reused. Recycling a mattress can be as beneficial as recycling the metals found in e-waste. (more…)
Kommenden Sonntag beginnt in den USA die Ausstrahlung der achten und letzten Staffel von „Game of Thrones“, einer der meistdiskutierten Fernsehserien der vergangenen Jahre. Was uns der Erfolg der Serie über unsere kollektive Psyche verrät, hat sich der Bildungswissenschaftler und Psychologe Gerald Poscheschnik näher angesehen. (more…)
A brand new method has been developed by scientists at Plymouth Marine Laboratory (PML) and the University of Exeter, in collaboration with Abertay University and Greenpeace Research Laboratories, to investigate links between top predator diets and the amount of microplastic they consume through their prey, offering potential insights into the exposure of animals in the ocean and on land to microplastics.

Forscherteam präsentiert in Nature Communications die erste globale Analyse von Höhlentropfwasser
Die in Karsthöhlen vorkommende Tropfsteine Stalagmiten und Stalaktiten geben wertvolle Hinweise auf das bisherige Erdklima. Wissenschaftlerinnen und Wissenschaftler benutzen die Zusammensetzung von Sauerstoffisotopen in Stalagmiten als Klimaarchiv, das wichtige Informationen zu früheren Klimawandeln gespeichert hat. (more…)
