UC biologist Joshua Gross studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. In a study, supported by the National Science Foundation, Gross looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
People whose eyes dilated more performed better on tests of working memory.
Microscope images could be obtained much more quickly—rather than one pixel at a time—thanks to a new imaging method for neutral atomic beam microscopes developed by Swansea University researchers. It could ultimately lead to engineers and scientists getting faster results when they are scanning samples.
Following NASA ’s DART mission, which successfully tested asteroid deflection techniques by colliding with the moonlet Dimorphos, extensive research has revealed insights into the geological features and evolutionary history of the Didymos asteroid system.
Studies have characterized the surface and interior of these celestial bodies, examined their formation processes, and assessed their response to impacts. These findings not only provide a clearer understanding of binary asteroid systems but also enhance planetary defense strategies.

A magnet-and-coil system reveals how acoustic waves reflect and refract when the host medium suddenly changes elasticity.
Learn about the Science of Intelligence through video lectures organized into series aimed at a general audience, the undergraduate level, and the research community.
The first-ever detonation engine could be the future (and the end of combustion): It has predicted by Hawking, and finally created by engineers.
A new study now published in Science reveals that the memory for a specific experience is stored in multiple parallel “copies.” These are preserved for varying durations, modified to certain degrees, and sometimes deleted over time, report researchers at the University of Basel.
The ability to turn experiences into memories allows us to learn from the past and use what we learned as a model to respond appropriately to new situations. For this reason, as the world around us changes, this memory model cannot simply be a fixed archive of the good old days.
Rather, it must be dynamic, changing over time and adapting to new circumstances to better help us predict the future and select the best course of action. How the brain could regulate a memory’s dynamics was a mystery—until multiple memory copies were discovered.
