A United States nationwide measles outbreak has led health officials to quarantine dozens of people at two Los Angeles universities, officials said on Thursday. The quarantine affects the University of California, Los Angeles (UCLA) and California State University, Los Angeles (Cal State LA) and comes as the United States battles the highest number of measles cases since the country declared the virus eliminated in 2000.
Kelp forests grow along coastlines worldwide, largely hidden from view. Like rainforests, they're among the planet's most important ecosystems: beautiful but fragile habitats for a wide array of plant and animal species. But scientists believe kelp forests are being threatened by climate change. Now, researchers from UCLA and seven other universities have an improved tool for tracking these shifting ecosystems, the largest of which is about 5 miles long.
