NASA’s New Exoplanet Satellite Has a Better Shot of Finding Life Close to Home
If humans ever leave this solar system, they probably won't do it aimlessly. More likely they'll set a course for some distant waypoint, perhaps another solar system, to visit, study, or maybe even settle. And when they do, there's a good chance the destination they choose will have been discovered by NASA's new planet-hunting spacecraft.…
You Know Who's Really Addicted to Their Phones? The Olds.
Millennials, we’re assured by endless headlines, are the people most addicted to their devices. Addled by social networking, obsessed with taking selfies and hustling for likes, youngsters can’t put their damn phones down. Amirite? Nope. That is wrong. The data suggests that the ones most hooked on their devices are those graying Gen Xers. Research by…
Patients Want Poop Transplants. Here's How to Make Them Safe
Neill Stollman has been called the Tupac of poop transplants. The Oakland-based, board-certified gastroenterologist didn’t invent the treatment. But he did bring it to the west coast. His first patient was a woman in her 80s with a horrible case of Clostridium difficile, a gut infection that can strike patients after a course of antibiotics…
Some Frogs May Be Developing a Resistance to the Disastrous Chytrid Fungus
The dreaded chytrid fungus Batrachochytrium dendrobatidis horrifies even the most sober-minded scientists. It grows on a frog’s ultra-sensitive skin, disrupting the organ's ability to absorb water and air. Considering the number of species the fungus impacts and its ability to rapidly drive them to extinction—as it’s done to hundreds of species so far—it’s considered “the…
Insect-Borne Diseases Have Tripled. Here's Why.
The year 2004 was a simpler time to be an infectious disease doctor in the US. Zika and chikungunya hadn’t yet emerged. Mystery RNA viruses weren’t spreading by tick bite around America’s heartland, killing farmers and ranchers. Certainly no one was on the lookout for a meat allergy caused by a tick with a white…
How Cells Pack Tangled DNA Into Neat Chromosomes
A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ball of yarn—diffuse, disordered, chaotic. But that messiness poses a problem during mitosis, when the cell has to make a copy…
This Trucking Company Keeps Spacecraft Safe on the Interstate
When I ask Bradley Worthington to tell me about that one time people in the southwest thought his trucking company, McCollister's, was moving a UFO across the country, he laughs. There’s not a “that one time.” “It happens frequently,” he says, “especially with oversized things.” And McCollister's hauls a lot of oversized things. From astronaut…
A New Startup Wants to Use Crispr to Diagnose Disease
In 2011, biologists Jennifer Doudna and Emmanuelle Charpentier published a landmark paper introducing the world to Crispr. The arcane family of bacterial proteins had a talent for precisely snipping DNA, and one of them—Cas9—has since inspired a billion-dollar boom in biotech investment. Clinical trials using Cas9 clippers to fix genetic defects are just beginning, so…
Norovirus Is a Terrible Gut Bug. The Olympics Could Make It Worse
This one’s going to be gross. Bear with me. According to the South Korean news agency Yonhap, 1,200 security personnel at the Winter Olympics in PyeongChang have been confined to quarters after 41 of them started vomiting and experiencing diarrhea. Tests showed they were infected with norovirus, the last best reason you need to avoid…
Big Data Suggests Big Potential for Urban Farming
This story originally appeared on CityLab and is part of the Climate Desk collaboration. Gotham Greens’ boxed lettuces have been popping up on the shelves of high-end grocers in New York and the Upper Midwest since 2009, and with names like “Windy City Crunch,” “Queens Crisp,” and “Blooming Brooklyn Iceberg,” it’s clear the company is selling a story as…
