Though she's a fossil, Sue is a true Chicagoan and has been on display in her home at The Field Museum since 2000.

Like many of us these days, Sue is sassy and shares her hot takes on Twitter with adoring fans.

It's hard to imagine that a blue dye sold in pet food stores in the U.S. to fight fungal infections in tropical fish could be a potent weapon against malaria.

A long time ago, when I was working on my Ph.D. research, I learned to use supercomputers to track the complex 3-D motions of gas blown into space by dying stars.

Using big computers in this way was still new to lots of researchers in my field and I was often asked, "How do you know your models are right?"

About Allan Adams

Karen Byrne's left hand sometimes operates on its own terms. It has unbuttoned shirts and stubbed out cigarettes, without her permission. Oh, and a few times, her own hand has slapped her across the face.

This is a documented medical occurrence, not a premise for a Jim Carrey movie. The condition's name? Alien hand syndrome.

A lick of cold, creamy gelato isn't just magic. It's mathematics.

"You have to respect the range," emphasizes Gianpaolo Valli, a senior instructor at Carpigiani Gelato University in Bologna, Italy, who has spent decades drilling aspiring gelato chefs on the right ratio of solids to water in any given recipe. (FYI: Solids need to be between 32 and 46 percent.) If your numbers are off, you're likely to end up with a disaster instead of a dessert.
