Can reducing ultra-processed foods help ease depression? Potentially, a small study finds—but making the change can prove challenging: “Food companies work with scientists to find just the right amount of sugar, salt and fat that make you want to eat more and more." ucsfh.org/4hanHnb

Before this year, the Bay Area weather service office had never issued a coastal flood advisory in September. This week’s advisory marks the second such instance this month, an indication of El Niño’s capacity to raise the seas that will only grow into winter.
