You’re a ball of anxiety: head pounding, jaw clenched. And you could feel worse down the line, since on-going stress can wreak havoc on your health. But new devices help you stop tension by picking up on early warning signs. They precisely monitor a bevy of biological stats, wirelessly deliver the data to your computer or phone in real time, and guide you in calming exercises that help you chill out instead of losing your cool.

After spending $100,000 on a car, you don’t expect the lightweight carbon-fiber trim to turn yellow and peel in the sun. But that’s the downside for carbon fiber with clear-coat (instead of colored) paint, as GM found when testing materials for the 2004 Corvette Z06 Commemorative Edition. So the company redesigned the clear coat and the epoxy resin binding the carbon fibers in the roof and trim of the 2009 Corvette ZR1.

It could be an aerial photo of an oil spill: liquid spheres pooling, oozing, dwarfing a bedraggled landscape. I half expect to zoom in on poisoned seal pups or waterbirds dragging their oil-soaked feathers. But the scene is microscopic. The “landscape” is made of E. coli. And what’s happening is exactly the opposite of what it seems. The little bugs aren’t drowning in fuel. They’re making it.

Shifting through the mossy undergrowth of Germany’s Black Forest, antennae raised and leg joints quietly clicking forward, OLE (pronounced “oh-luh”) is a St. Bernard–size bug on the prowl. But this mechanized insect isn’t a scavenger—it’s a guardian.

He says go straight for three miles and turn east. She says drive past the school and turn right at the green house. Both sets of directions will get you to the same grocery store just as easily, but they embody the language barrier between the sexes that lurks behind many a front-seat argument.

Nobody ever accused the bat of being beautiful. But its ugliest features—its freakishly ornate ears and intricately furrowed mouth—play a key part in the animal’s uncanny ability to track its prey. The mystery is how.

If the biotech industry has its way, ordering a hamburger might soon sound something like this: “one charbroiled cloned-beef patty, with genetically modified cheese, lab-grown bacon and vitamin-C-fortified lettuce, on a protein-spiked bun.” The burger of the future is delicious, nutritious and contains more engineering than a stealth bomber.
