Though they live only a few hours before dividing, bacteria can anticipate the approach of cold weather and prepare for it. The discovery suggests that seasonal tracking is fundamental to life.

Cancer treatment has come a long way in recent decades. But finding the best course of treatment for each case of this diverse, dynamic disease remains a challenge. In this episode, co-host Steven Strogatz speaks with computational biologist Franziska Michor about how math, statistical models and machine learning may be critical to the next generation of cancer care.

Invisibly to us, insects and other tiny creatures use static electricity to travel, avoid predators, collect pollen and more. New experiments explore how evolution may have influenced this phenomenon.

Extremophiles, or microbes that live in the most seemingly hostile environments, are the darlings of astrobiologists, who study the potential for life beyond Earth. In this episode, co-host Janna Levin speaks with astrobiologist and cave explorer Penelope Boston about how life finds a way — and whether it might have found a way elsewhere in our solar system or around a distant star.

Cells across the tree of life can swap short-lived messages encoded by RNA — missives that resemble a quick text rather than a formal memo on letterhead.

Cell membranes from comb jellies reveal a new kind of adaptation to the deep sea: curvy lipids that conform to an ideal shape under pressure.

Like a highway system, the vagus nerve branches profusely from your brain through your organs to marshal bodily functions, including aspects of mind such as mood, pleasure and fear.

Proteins are often visualized as cascades of curled ribbons and twisted strings, which both reveal and conceal the mess of atoms that make up these impossibly complex molecules.

Sébastien Calvignac-Spencer searches museum jars for genetic traces of flu, measles and other viruses. Their evolutionary stories can help treat modern outbreaks and prepare for future ones.
