Biologists at UC San Diego have discovered that bacteria—often viewed as lowly, solitary creatures—are actually quite sophisticated in their social interactions and communicate with one another through similar electrical signaling mechanisms as neurons in the human brain.
In a study published in this week’s advance online publication of Nature, the scientists detail the manner by which bacteria living in communities communicate with one another electrically through proteins called “ion channels.”
A UC San Diego study of the underground “architecture” of harvester ant nests has found that the more connected the chambers an ant colony builds near the surface entrance, the faster the ants are able to collect nearby sources of food.
The reason is simple: Increased connectivity among chambers leads to more social interactions among the ants within the nest. So when one group of ants within a colony—comprised of individuals working toward a common goal—finds a particularly good source of food, it’s able to more quickly communicate that finding to the rest of the colony.
Cisplatin is part of the chemotherapy treatment programs for many of the most common types of cancer. This important drug has now been shown to play an unexpected role in blocking one of the pathways most commonly involved in driving the growth of cancers, according to a recent study by researchers at the San Diego Supercomputer Center (SDSC) as well as the university’s Moores Cancer Center and Department of Neurosciences.
Researchers in the UCSD Robotics lab have developed a duct-exploring robot based on the principles of tensegrity, a structural design paradigm which combines components under pure tension and pure compression to make mass efficient, accurately controllable structures.

A teenage girl faced with sudden rapid heart deterioration, a man in the prime years of his life suffering from debilitating heart failure and a former NFL athlete crippled by end-stage heart failure were all successfully treated with a surgical approach pioneered by cardiac experts at University of California, San Diego School of Medicine.
The Center for U.S.-Mexican Studies at the University of California, San Diego presents a diverse lineup of policy, scholars and community leaders for its annual symposium, Mexico Moving Forward. Called “Recapturing the Mexico Moment,” this year’s all-day event will be held Friday, Oct. 30, culminating in a Dia de los Muertos celebration with decorated altars and a live mariachi band.
