Don’t Blame Pigs for Swine Flu—Species Hopping Is How Viruses Evolve
When new species evolve, where do their viruses come from? As little more than free-ranging bundles of genetic material, viruses desperately need to hijack their hosts’ cellular machinery and resources to replicate, over and over again. Without its host, a virus is nothing. Because of that dependence, some viruses have stuck with their hosts throughout…
Buried in a Gold Mine, a Particle Accelerator Searches for Stellar Secrets
In August 2015, scientists from the University of Notre Dame went west, the disassembled pieces of a particle accelerator secured in the back of their U-haul. Over 1,000 miles later and nearly a mile down, they started installing the machine in a new home: deep within an old mine in the town of Lead, South…
Meet The X-Ray Visionary Looking for Signs of Life on Mars
Abigail Allwood is a translator. But instead of reading ancient texts, she reads ancient rocks, and for the past decade, the Australian astrobiologist has been exploring the most remote wilderness on earth in search of microscopic fingerprints of life. She uses a tool called the PIXL, which she invented as a postdoc: It fires a…
Light-Triggered Genes Reveal the Hidden Workings of Memory
Susumu Tonegawa’s presence announces itself as soon as you walk through the door of the Massachusetts Institute of Technology’s Picower Institute for Learning and Memory. A three-foot-high framed photograph of Tonegawa stands front and center in the high-ceilinged lobby, flanked by a screen playing a looping rainbow-hued clip of recent research highlights. Quanta Magazine About…
Meet Salto, the One-Legged Robot With an Incredible Leap
Day by day, human beings grow more and more inadequate. Robots steal our jobs. They can burn us in a foot race. And they can even read our damn minds. Now a little robot from the University of California Berkeley is putting on a jumping clinic. Meet Salto, the bot that not only leaps four…
Neil deGrasse Tyson Wants You to Explore Deep Space—In a Video Game
There's a new video game in development for all you science nerds, and it has an advisor you might recognize. No, not me—just another one of your favorite physicists-turned-science educators, Neil deGrasse Tyson. The game is Space Odyssey, a space exploration caper that takes you on a journey to explore and settle new planets. Currently,…
How You Could Get an Early Warning for the Next Big Earthquake
At 2:39 am Thursday morning, millions of Bay Area residents from Sacramento to San Jose were shaken awake by the rolling tremble of a 4.4 magnitude earthquake. The eight-mile deep tremor struck along the Hayward fault, two miles southeast of Berkeley. From my apartment just 20 blocks from the epicenter, I woke with the rest…
Clever Machines Learn How to Be Curious (And Play Super Mario Bros.)
You probably can’t remember what it feels like to play Super Mario Bros. for the very first time, but try to picture it. An 8-bit game world blinks into being: baby blue sky, tessellated stone ground, and in between, a squat, red-suited man standing still—waiting. He’s facing rightward; you nudge him farther in that direction.…
New Science Could Sharpen Crispr's Gene-Editing Scalpel
Stay on target. That’s the mantra you hear in labs and biotech companies around the world as they snip away at DNA. All the techniques for gene editing—from the famous Crispr-Cas9 to the older TALENs and zinc-finger nucleases—share a problem: Sometimes they don’t work. Which is to say, they have “off-target effects,” changing a gene…
Google's Health Spinoff Verily Joins the Fight Against PTSD
The symptoms of post-traumatic stress disorder include uncontrolled memories of a traumatic event, anxiety and panic—“hyperarousal” is the technical term—depression, avoiding anything that’s a reminder of the event, self-destructive behavior, and more. It’s the only psychiatric disorder where people are pretty sure of the cause: emotionally traumatic events, from the death of a loved one…
