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.
When a rapidly-growing cell divides into two smaller cells, what triggers the split? Is it the size the growing cell eventually reaches? Or is the real trigger the time period over which the cell keeps growing ever larger? A novel study published online today in the journal Current Biology has…
Physicists have come up have with a mathematical explanation for moths’ remarkable ability to find mates in the dark hundreds of meters away.
The evolution of worms, insects, vertebrates and other “bilateral” animals—those with distinct left and right sides—from less complex creatures like jellyfish and sea anemones with “radial” symmetry may have been facilitated by the emergence of a completely new "operating system" for controlling…
Let’s say you’re a bee and you’ve spotted a new and particularly lucrative source of nectar and pollen. What’s the best way to communicate the location of this prize cache of food to the rest of your nestmates without revealing it to competitors, or “eavesdropping” spies, outside of the colony?
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
Biologists at UC San Diego have found the “missing link” in the chemical system that enables animal cells to produce ribosomes—the thousands of protein “factories” contained within each cell that manufacture all of the proteins needed to build tissue and sustain life.
