An international team of astronomers, including UC San Diego astrophysicists, has discovered three Earth-sized planets orbiting near the “habitable zone” of an ultracool dwarf star, the first planets ever discovered around such a tiny and dim star. The planets are so close to Earth—only 40 light years away—that astronomers should eventually be able to study in greater detail the composition of each of the planets and their atmospheres as well as look for chemical signals of life.
For Transgender Day of Visibility, UC San Diego alumna Hillary Whittington returned to campus as a proud mother of two, PTA volunteer, public speaker—and parent of a transgender child. She and her husband, Jeff, were on campus to discuss Hillary’s new book, “Raising Ryland: Our Story of Parenting a Transgender Child with No Strings Attached.” The memoir tells of both the resistance and support Whittington and her family encountered during their child’s transition from female to male.
The personalized collections of microorganisms, known as our microbiome, are increasingly recognized for their influences on everything from allergies to obesity. These types of studies typically take months or years—too long for that data to be medically useful. Researchers at the UC San Diego Center for Microbiome Innovation used a study with the 2016 San Diego Fermentation Festival as a test case for a first-of-its-kind rapid response system.
