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…
A biologist at UC San Diego is one of 18 scientists nationwide who this year will receive the prestigious Packard Fellowship for Science and Engineering, given to promising early-career scientists from the David and Lucile Packard Foundation.
With their tiny forelimbs and long hindlimbs and feet, jerboas are oddly proportioned creatures that look something like a pint-size cross between a kangaroo and the common mouse. How these 33 species of desert-dwelling rodents from Northern Africa and Asia evolved their remarkable limbs over the past…
An international team of researchers has identified a protein that helps heart muscle cells regenerate after a heart attack. Researchers also showed that a patch loaded with the protein and placed inside the heart improved cardiac function and survival rates after a heart attack in mice and pigs.
A study conducted by biologists at UC San Diego has found that the Africanized honey bee—an aggressive hybrid of the European honey bee—is continuing to expand its range northward since its introduction into Southern California in 1994.
An international team of scientists headed by biologists at UC San Diego has discovered that an important class of stem cells known as human “induced pluripotent stem cells,” or iPSCs, which are derived from an individual’s own cells, can be differentiated into various types of functional cells…
Far from being selfish organisms whose sole purpose is to maximize their own reproduction, bacteria in large communities work for the greater good by resolving a social conflict among individuals to enhance the survival of their entire community.
Laboratories that test chemicals for neurological toxicity could reduce their use of laboratory mice and rats by replacing these animal models with tiny aquatic flatworms known as freshwater planarians, according to study by UC San Diego scientists.
Chemists and biologists at UC San Diego have succeeded in designing and synthesizing an artificial cell membrane capable of sustaining continual growth, just like a living cell.
Physicists at UC San Diego have developed a new way to control the transport of electrical currents through high-temperature superconductors—materials discovered nearly 30 years ago that lose all resistance to electricity at commercially attainable low temperatures.
