When Lisbeth Ceriani was diagnosed with breast cancer, she wanted a blood test to find out if she carried one of the two dreaded BRCA genes, which could increase her risk of ovarian cancer by up to 50 percent. She decided that if she were a carrier, she would have doctors remove her ovaries. But the sole purveyor of the BRCA tests, Utah-based Myriad Genetics, refused her insurance. Myriad holds the patent on the BRCA genes, and thus exclusive R&D rights, so there were no alternative tests, and Ceriani found herself unable to make a decision about her future health.

I learned a lot of interesting scientific facts while writing Absinthe and Flamethrowers: Projects and Ruminations on the Art of Living Dangerously. Here are five ways to (safely) add a little danger to your life.

Researchers have known for decades that concrete fixes itself as cement particles near a small crack mix with air and water to form calcium carbonate. But some fractures are too big to heal on their own. Now engineers at the University of Michigan have mixed a new concrete formula with reinforcing glue-like fibers that hold it together under pressure, allowing only hair-width cracks that can mend after a rainy day. Available in a few years, the remixed concrete will cost more than the standard stuff, but less maintenance could make it cheaper in the long run.

Nothing motivates like peer pressure, whether it’s friends goading you into one shot too many or friends tracking your power consumption on Twitter. That’s the thinking that led Limor Fried and PopSci contributing editor Phil Torrone, circuit wizards who run the electronics-kit seller adafruit.com, to cross a small power monitor with an XBee wireless home-automation module and a few lines of code.

Swine flu, nuclear tests, global warming—signs of impending doom abound. Should the unthinkable happen, the smart survivalist has two options: flee the planet or, for those of us who aren’t Richard Branson, stock up on gear that will meet your basic needs during Armageddon. If the world doesn’t end, you can always take your new gadgets camping.

It doesn’t. That’s what Coca-Cola’s spokespeople say, anyway. “The great taste of Coca-Cola is the same regardless of the package it comes in,” they insist. Rather, they say, “the particular way that people choose to enjoy their Coke can affect their perception of taste.” Sure, most people would agree that the cola is indeed delicious and refreshing, and pouring it into a glass or serving it over ice could influence the sensation of its flavor.
