Walk This Way: Body Designs Head to Toe

When you examine what makes us tick, you find intelligent design from the top down and from the bottom up.

Breaking! Dino Blood Is Real

Blood vessels found in a hadrosaur said to be 80 million years old are the real original material, researchers say.

Cell's Molecular Machines Arouse Fascination

With increasing image quality at their disposal, biologists are finding amazing molecular machines at work in living cells.

Your Cells Work for You

At a cellular level, the human body has a dizzying array of workers. Here are a few recent examples discovered.

Muscle Power Is Designed, Not Evolutionary

The wonder of muscle inspires both awe at its design and opportunities for evolutionary storytelling.

Molecular Motors Put a Spring in Your Step

When you feel in spring in your step, thank tiny molecular motors in your muscles and tissues that make it possible.

Cells Optimize Their Tasks

The key to design in manufacturing is optimization – hitting the “sweet spot” between competing interests. It’s not always possible to have all the elements of a product be ideal. A laptop computer, for instance, can’t have an extra-large monitor and simultaneously have long battery life and compact design. A muscle car cannot be expected to have the best gas mileage. In the heyday of “faster, better, cheaper” spacecraft, engineers often joked, “pick any two.” In the same way, living cells have to optimize their operations. A couple of recent papers explore how they find that sweet spot.
