The tallest dam in the United States is the site of a major emergency response. California’s Oroville Dam holds a reservoir containing 1.1 trillion gallons of water, providing water—and power—to much of the state. Recent weather events caused it to fill up way above normal capacity. Concrete in the 50-year-old dam’s main spillway, designed to handle overflow, crumbled, forcing managers to use the auxiliary or emergency spillway. Water pouring from the emergency spillway caused damage to the ground below, putting that spillway at risk of collapsing and leading to an evacuation of more than 180,000 nearby residents. The situation has since stabilized and people have been told they can return home, but workers are still rushing to make repairs and shore up the dam ahead of approaching storms.

A cockroach crawling up your nostril and lodging itself inside your head is probably not a diagnosis most doctors have considered. So maybe it’s understandable that when a woman living near Chennai, India, complained of a pain in her nose that was keeping her from getting to sleep, the first doctor she consulted didn’t reach that correct diagnosis. He told the woman the pain should resolve on its own. Fortunately, a second physician referred her to Chennai’s Stanley Medical College and Hospital, where the ENT Department discovered the embedded insect. Using endoscopy, they succeeded in pulling the still-living roach from a sinus cavity through the nose. Dr. M.N. Shankar, head of ENT at Stanley, remarked that the procedure may have prevented a possible infection of the brain.
