The United States was the world’s largest source of carbon emissions for more than a century. In a new analysis, researchers document the changing trends in U.S. carbon emissions from the late 19th century to the early 21st century, focusing on emissions from fossil fuels and industry. They discuss the main factors that contributed to the rollercoaster of changes in historical carbon emissions. The authors close by offering lessons from the U.S. experience for developing countries.

UC Irvine is one of the first two California universities selected for a national program training faculty to integrate evidence-based psychedelic therapy into health education.

 

Research increasingly supports the use of psychedelics in treating difficult mental health conditions such as depression, anxiety, PTSD and addiction.

Study identifies that uranium’s isotopic composition can be used as a biomarker to noninvasively measure accumulation of uranium in the kidneys. Uranium from drinking water can accumulate in the kidneys—even at low levels of exposure—and this newly identified biomarker may serve as an early warning sign of kidney damage. The findings suggest a potential breakthrough in detecting and preventing chronic kidney disease caused by uranium toxicity. This discovery offers critical insights into a largely overlooked environmental health threat.
