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.
On March 29, 2019, fifteen cases of Ebola were reported in the Democratic Republic of Congo. It was the biggest one-day spike in an outbreak that started last summer and was deeply worrisome for a few reasons: Ebola has a mortality rate of at least 50 percent, according to the World Health Organization (WHO), and spreads quickly through contact with bodily fluids. Also, the sudden uptick in cases could presage a rapid expansion of the virus throughout the entire Congo Basin and beyond.

Eureka! The Diving Bell and the Bullet Wound
On August 4, 1919, Berkeley chemist Joel H. Hildebrand (above, right) was shot and wounded by a lab assistant who accused the professor of opposing his application for appointment. Hildebrand survived—fortunately for the Navy. Twenty years later, in 1939, his work on the properties of gasses being dissolved into liquids saved the lives of 33 members of the USS Squalus when their submarine sank.
The annual flu season is in full career across most of the country and parts of California have been particularly hard hit. We reached out to Arthur Reingold, head of epidemiology at UC Berkeley’s School of Public Health, for some answers about the nature of the influenza virus, what we can do to control it, and the risk of another flu pandemic like the one of 1918.
