In late June, visitors find the doors of Berkeley City Club locked, signs imploring would-be entrants to wear masks. The club, originally imagined as a space to foster women’s civic engagement, was designed by the famed architect Julia Morgan (B.A. 1894). There’s a swimming pool inside, its untouched water reflecting the aquamarine, cloistered arch ceiling above. Where there should be the echo of rhythmic splashing bouncing off tile, there’s a cavernous silence.
Researchers Investigate How to Decontaminate Masks for Reuse
There aren’t enough tests. That’s the problem now on many of our minds.
The idea for the testing facility was born just two weeks ago, when a virologist in Jennifer Doudna’s lab saw her own projects put on hold.

On July 17, Instagram announced the unthinkable: the company was exploring the idea of hiding the number of “likes” from its photo-sharing platform. According to the company, the new design would encourage “followers to focus on the photos and videos you share, not how many likes they get,” ostensibly shifting the emphasis away from the quantity of likes to the quality of content.

One of biology’s wilder facts is that we’re all family. You and me, sure, but also me and a mushroom. Triceratops shared genes with you. So does the virus that makes you cough, and a rosebush. Bacteria left us on the tree of life around 2.7 billion years ago, but the wet world they came from is still ours: One code runs all of life. The same proteins that imprint memories in your neurons, for example, do so in octopi, ravens, and sea slugs. This genetic conservation means tricks from one species can be hijacked. If you stick a jellyfish gene in a monkey, it’ll glow green.
IN THE SUMMER OF 1984 the senior scientists of Cetus Corp., a Berkeley biotech company, found themselves in a bind. One of their employees, a promising young scientist named Kary Mullis, had dreamed up a technique to exponentially replicate tiny scraps of DNA. He called it polymerase chain reaction (PCR), and if it worked it would change the world and likely earn Cetus a mountain of money. The only problem was Mullis was an interpersonal wrecking ball.
Blue is an elusive color. Crush the feathers of a blue jay or the wings of a Morpho butterfly and you’ll see gray dust; our perception of their electric blue hue depends on microscopic structural features that bend the light just so. The blue sky is merely a mirage of refracting light, as are blue eyes. Truly blue pigments are exceedingly rare in the natural world, which is perhaps part of their allure—blue is our favorite color, according to an international, cross-cultural survey.
ON APRIL 24, 1981, THE BODY OF A YOUNG WOMAN with auburn braids and a fringed jacket was discovered off the side of a road in Troy, Ohio.
She had been strangled to death only hours before. Authorities took DNA samples but couldn’t find a match for the woman. For decades, she was described only by the clothes on her back: “Buckskin Girl.”
