A biophysicist and an astrophysicist at UC San Diego have been named 2016 Cottrell Scholars, an award given this year to only two dozen scientists nationwide. Eva-Maria Schoetz Collins, an assistant professor of physics and biology, and Dusan Keres, an assistant professor of physics, will each receive $100,000 awards for research and teaching given annually to the top early career academic scientists by the Research Corporation for Science Advancement.

A team of biologists and biomedical researchers at UC San Diego has developed a new method to determine if bacteria are susceptible to antibiotics within a few hours, an advance that could slow the appearance of drug resistance and allow doctors to more rapidly identify the appropriate treatment for patients with life threatening bacterial infections.

Biologists at UC San Diego have found that a method they developed to identify and characterize new antibiotics can be employed to screen natural products quickly for compounds capable of controlling antibiotic resistant bacteria.

Wine, beer and yogurt are produced when microorganisms convert sugar into alcohol, gases or acids. But this process of fermentation—which is used by bacteria, fungi and other fast-growing cells to generate energy in the absence of oxygen—is a much less efficient way of generating energy for cells than aerobic respiration.
So why do many organisms use this seemingly wasteful strategy to generate energy instead of aerobic respiration, even when oxygen is readily available?

Using a groundbreaking gene editing technique, biologists at UC San Diego, working in collaboration with biologists at UC Irvine, have created a strain of mosquitoes capable of rapidly introducing malaria-blocking genes into a mosquito population through its progeny, ultimately eliminating the insects’ ability to transmit the disease to humans.

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.
