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.
The Sad Last Days of the Woolly Mammoth
Hoping to shed light on the woolly mammoth’s decline, UC Berkeley bioinformatics researcher Montgomery Slatkin and a colleague compared the genomes of two of the hairy giants and found that they were mutational hot messes in their last days, with trouble finding where to pee and translucent satin coats that may have looked cool at parties but were hardly enough to protect them from the elements.

How’s this for a modern take on the venerable office vending machine? You swipe your credit or debit card, open a fridge-like glass door, and choose from an array of fresh entrees and snacks. If you want a receipt, the machine will email it to you, and it keeps track of your preferences: next time there’s a sale on your favorite yogurt, Byte Food’s cloud-based servers will give you a heads up.

On August 28, 1789, Thomas Jefferson wrote to James Madison from Paris about the French revolutionaries, relaying an important piece of strategic information: “Mirabeau is their chief.”

In a corner of the Digital Imaging Lab in the basement of UC Berkeley’s Moffitt Library, recent graduate Olivia Dill is checking on the latest shipment of fragile wax recordings from the Phoebe A. Hearst Museum of Anthropology. These hard wax tubes, invented by Thomas Edison in the 1880s, are one of the earliest sound recording media.

A new study led by UC Berkeley Lab researcher Trevor Keenan suggests that increased plant growth is slowing the accumulation of carbon dioxide in the atmosphere, a finding that could help explain the mystery of why the uptick in CO 2 concentrations has leveled off since 2002, even as emissions have increased. “We believed one of the planet’s main carbon sinks had unexpectedly strengthened,” Keenan explained in a Lab press release. “The question was: which one?”
Got a lousy night’s sleep? Feeling kinda grouchy? Turns out waking up on the wrong side of the bed won’t just make you cranky. It will make others seem that way, too. A 2015 study from the UC Berkeley Sleep and Neuroimaging Laboratory found that a single sleepless night can fundamentally alter the way we perceive others—making even the mellowest of fellows seem like the strangest of dangers.
Ever hear that old cliché “This ain’t rocket science?” I wouldn’t use it around Ashley Chandler Karp because what she does is rocket science. A propulsion engineer at NASA’s Jet Propulsion Laboratory in Pasadena, she’s helping design the next generation of rockets, which will bring samples from Mars back to Earth for more extensive testing than can be done on the Martian surface.
As if that weren’t ambitious enough, they also have to figure out a way to transport the stuff here without getting any contamination from the Red Planet on the container.
This interview has been edited for clarity.
1. How would you describe the route that led you to a simulated Mars mission?
Lately, I’ve been spending time at Founders’ Rock trying and mostly failing to get a grasp on reality.
Founders’ Rock is an outcropping at the northeast corner of the UC Berkeley campus, where Gayley Road and Hearst Avenue meet, a lonely spot shaded by toyon, oak, and eucalyptus. The rock itself—lichen-encrusted and moss-fringed—is an unassuming jumble.
As a 10-year-old growing up in Shanghai, Jun-Yan Zhu often avoided homework with furtive doodling. He’d sketch comics or movie characters in pencil, then erase the evidence before his mother saw it. Much as he loved drawing, however, he wasn’t very good at it. He dreamed of a world where everyone, even those who lacked the talent, could easily communicate in pictures.
Road rage is hardly an acceptable response to the travails of driving. It signals inadequate impulse control, perhaps even sociopathy. People can end up hurt, incarcerated, or worse.

Even those of us who don’t reflexively shriek “Go Bears” every four or five minutes know that UC Berkeley is one of the finest universities on the planet. The proof is in the sheepskin; if a Cal degree isn’t always a fast track to an executive suite or academic renown, it at least constitutes a reliable on-ramp.
But is that the case just for American students? What about the developing world? Berkeley bona fides can be of inestimable value in Silicon Valley, but is the same true for Mombasa?

Enter any grocery store franchise and prepare to be worked. It’s almost Halloween so you’ll see pumpkins, candy, straw, and speckled corn garnishing produce bins overflowing with honeycombed stacks of shiny, plump fruit. You’ll smell flowers, fresh bread, and deli meats. If you came at the right time you might hear a faint thunderstorm in the produce section and see soft mist falling on dewy greens.
“Have you tried Advanced Listerine?” A voice might chirp from the ceiling.
