Whether we like to or not, we’re all gamblers.
Every waking moment, countless stem cells inside our bodies are dividing in order to replace worn out biological machinery. But every time these perfectly healthy cells divide, roughly three mistakes occur in the genetic code—no one’s perfect. These mutations, though unpredictable, are typically benign, but sometimes this molecular game of Roulette takes an unlucky turn.
“Most of the time these mutati ...read more
Seafloor sediment is home to a vast repository of slow-growing, slow-evolving microbes. (Image: NOAA)
On the seafloor, “marine snow” is constantly falling. Bits of dead plankton, decaying fecal material, biological remnants from shore – it all finds its way to the bottom of the ocean, delivering needed sources of organic molecules and energy to the microbial communities lying in wait.
Over time, this snow – along with sediment mineral grains – accumulates, burying ...read more
The United States Endangered Species Act is often considered to be the most powerful piece of environmental legislation not just in the US, but in the world. As a result, when the U.S. Fish and Wildlife Service (USFWS) formally lists a species as either threatened or endangered, it can be a game-changer for the species in question, protecting and even recovering a plant or animal that would otherwise be headed towards extinction. Such an action usually garners a fair amount of notice among conse ...read more

In the water cycle, what comes out of us eventually goes back in. Along the way, we can make it something better.
That’s the idea behind a new beer from San Diego’s Stone Brewery made from the city’s recycled wastewater. Their aptly named Full Circle Pale Ale uses water from Pure Water San Diego, a water treatment company that aims to supply one-third of the city’s water within the next two decades. They’ve partnered with the brewer ...read more
A new study about the relationships between species just knocked down our basic understanding of the dinosaur family tree. (Credit: Gary Larson/The Far Side)
Ask any obsessive dino-phile above kindergarten age to explain the dinosaur family tree and it’s likely the first thing you’ll hear is that all dinosaur species fall into one of two groups. It’s a core concept upon which our entire understanding of dinosaurs is built. But according to a new study, we got that most fu ...read more
