UC Berkeley plant scientists, working with colleagues from the University of Illinois, have successfully supercharged the photosynthesis cycle, allowing genetically altered tobacco plants to grow as much as 20 percent larger simply by using more sunlight.
More than 550 Berkeley students take your course Drugs and the Brain every year. What do you hope your students take away from the class?
Respect for the power of drugs, and specifically that all drugs are poisons as well as medicines. This is embedded in the ancient Greek word pharmakon. The origin of our words pharmacy, pharmaceutical, and pharmacology, it means both medicine and poison. While the ancients appreciated this dual property of drugs, it is often overlooked, even forgotten, in contemporary society.
Yesenia Guitron knew something was wrong at the bank branch where she worked. She was getting complaints from customers—many from Mexico and undocumented—that they were being charged for accounts they had never opened and were receiving debit cards they had never requested. Guitron, a personal banker at a local Wells Fargo in the Napa Valley town of St. Helena, began to realize that some of her colleagues, under intense pressure to open accounts, were doing so without customers’ knowledge.
To understand what’s happening on the surface of things, you must look deep within. That might be the guiding mantra of a trio of UC Berkeley geologists who are looking a hundred miles below the earth’s surface in order to better understand the tectonic forces that shape our planet.
It is a curious thing to consider that UC Berkeley, a school notably lacking a marine biology program, has produced not one, not two, but three published studies on the venerable octopus within the last year. But then octopuses, too, are curious to consider. They have three hearts; blue, copper-based blood; regenerating tentacles; and a level of sentience unique among invertebrates.
Eugene Chiang became a professor of astronomy at UC Berkeley in 2001 with the intention of contemplating the stars. But when he took on the role of writer, producer, director, prop/costume designer, and actor for the department’s annual holiday play, he became one himself, at least within the department.

In Apulia, Italy’s boot heel, the olive tree is sovereign.
“Olive trees pretty much cover the entire province,” says Rodrigo Almeida, an associate professor in Berkeley’s Department of Environmental Science, Policy and Management. “The olive tree defines Apulia’s identify. The people have a deep emotional connection to their trees. Families plant them to mark the births of their children. They cherish them.”

When we say “internal compass,” we’re usually referring to something metaphorical, a person’s innate sense of right and wrong. But for UC Berkeley microbiologists Arash Komeili and David Hershey, the term is literal: The two study magnetotactic bacteria, which navigate using tiny magnetic iron crystals called magnetosomes.
Turning an undesirable substance into something valuable seems like the plot of an old fable, but UC Berkeley researchers Chris Chang and Omar Yaghi may have done just that. Their invention, covalent organic frameworks, or COFs, can transform atmospheric carbon dioxide into a useful building block for biodegradable plastics, fuel, and more.
Chang likens COFs to TinkerToys, though at a nano scale. They consist of strings of carbon crystals that are special in their unique porosity, as they can be custom tailored to capture the chemical of choice.
Have you ever been engrossed in your favorite episode of Star Trek on your smartphone and thought “Hey! The color of Kirk’s uniform doesn’t look pure!” Yeah, most of us probably wouldn’t think that. But with quantum dots seeping into modern displays, our viewing expectations could drastically change.
In January, David Broockman, then a political science Ph.D. student at UC Berkeley, found something unusual about a study he and fellow student Joshua Kalla were trying to replicate. The data in the original study, collected by UCLA grad student Michael LaCour and published in Science last December, had shown that gay canvassers, sent door-to-door in California neighborhoods, could, after a brief conversation about marriage equality in which the canvassers disclosed their own sexual orientation, have a lasting impact on voter attitudes on the subject.
Robert Glushko’s job is to think about the organization of, well, everything: Ikea, zoos, spice racks, even crime families. He tries to get at the concepts behind how and why we arrange things, and what makes certain arrangements better than others. Take a bus, for example, says the UC Berkeley School of Information professor—it’s really just a vehicle traveling on a series of points on a graph. “If you replaced it with a spaceship, it wouldn’t matter,” he says. The ideas behind plotting a route would be the same.
Science tells us that race is in our heads, not in our genes; it’s all a social construct.
It’s an observation that seems to illuminate everything and nothing at once. It makes it sound so arbitrary and trivial—a trick of the mind. And yet history tells us that race has mattered enormously. And the news emphasizes how much it still matters today in terms of what researchers call “life outcomes”: Your chances of securing a loan, for example; or of getting a good education; or of being shot by the police.
It might sound slightly science fictional or possibly James Bond-ian, but this is what Dmitry Budker actually does: He shoots green lasers at colored diamonds.
