UCLA researchers have identified a previously invisible vulnerability in some of the most aggressive cancers known to medicine, while a separate team uncovered a shocking new trick that a notorious cancer-driving protein uses to help tumors survive chemotherapy. On the brain health front, scientists have pinpointed a brand-new trigger for Alzheimer's disease and already have an experimental compound designed to block it. Meanwhile, researchers discovered that tiny particles produced in the gut may be broadcasting aging signals throughout the entire body, opening a surprising new front in the fight against age-related disease. Rounding out the episode: humpback whales are making record-breaking solo ocean crossings, oak trees are outsmarting caterpillars in an ancient evolutionary arms race, and the mystery of a hidden planet in our own solar system just got a lot more complicated.
