Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or wandering.

Randy Katz, a computer scientist and Wi-Fi pioneer who served as the University of California, Berkeley’s vice chancellor for research for three years, during which time he shepherded the campus through a year-long phased reopening after a pandemic shutdown, will step down on June 30.

Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species add to their calls by visually showing off with the flap of a hand, a wave of a foot or a bob of the head. Conservation ecologist Rebecca Brunner has discovered that the glass frog Sachatamia orejuela can be added to the list of species that make use of visual cues in response to their acoustic environments. This is the first time a member of the glass frog family (Centrolenidae) has been observed using visual communication in this manner.
