Climate change is the result of many human activities, from carbon emissions to deforestation, and it will take multiple and varied interventions to mitigate it, including legislation, regulation, and market-based solutions implemented at local, national, and global levels. Demand-side factors, such as changes in social norms, can also help by creating political pressure for increased climate action. In addition, they can strengthen the efficacy of other interventions, for example by increasing the acceptance and adoption of new technologies or adherence to laws and regulations.
On Oct. 16, at 7:04 a.m. EDT, NASA's Lucy spacecraft, the first mission to the Jupiter Trojan asteroids, will skim the Earth's atmosphere, passing a mere 220 miles (350 kilometers) above the surface. By swinging past Earth on the first anniversary of its launch, Lucy will gain some of the orbital energy it needs to travel to this never-before-visited population of asteroids.
Scientists have begun turning to new tools offered by machine learning to help save time and money. In the past several years, nuclear physics has seen a flurry of machine learning projects come online, with many papers published on the subject. Now, 18 authors from 11 institutions summarize this explosion of artificial intelligence-aided work in "Machine Learning in Nuclear Physics," a paper recently published in Reviews of Modern Physics.
Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth on Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB)—the most powerful class of explosions in the universe—that ranks among the most luminous events known.
To accelerate gender parity in the field of wilderness medicine, in which women are significantly underrepresented, a team of researchers analyzed the gender distribution of key leadership roles at the Wilderness Medical Society (WMS) and among authors and reviewers of content published in WMS's official journal, Wilderness & Environmental Medicine (WEM). Their findings, which document past and current gender gaps, are reported in two related studies available in the current issue of WEM, published by Elsevier.
"Metabolism" describes the body's chemical changes that create the necessary materials for growth and overall health. Metabolites are the substances made and used during these metabolic processes—or, as a new discovery out of Scripps Research and its drug development arm, Calibr, indicates, they could also be potent molecules for treating severe diseases.
