1/ ELECTRIC COTHES
Physicists at Wake Forest University have developed a fabric that doubles as a spare outlet. When used to line your shirt — or even your pillowcase or office chair — it converts subtle differences in temperature across the span of the clothing (say, from your cuff to your armpit) into electricity. And because the different parts of your shirt can vary by about 10 degrees, you could power up your MP3 player just by sitting still. According to the fabric’s creator, David Carroll, a cellphone case lined with the material could boost the phone’s battery charge by 10 to 15 percent over eight hours, using the heat absorbed from your pants pocket.

2/ THE NEW COFFEE :
Soon, coffee isn’t going to taste like coffee — at least not the dark, ashy roasts we drink today. Big producers want uniform taste, and a dark roast makes that easy: it evens out flavors and masks flaws. But now the best beans are increasingly being set aside and shipped in vacuum-sealed packs (instead of burlap bags). Improvements like these have allowed roasters to make coffee that tastes like Seville oranges or toasted almonds or berries, and that sense of experimentation is trickling down to the mass market; Starbucks, for instance, now has a Blonde Roast. As quality continues to improve, coffee will lighten, and dark roasts may just become a relic of the past. Oliver Strand
3/ ANALYTICAL UNDIES :
Your spandex can now subtly nag you to work out. A Finnish company, Myontec, recently began marketing underwear embedded with electromyographic sensors that tell you how hard you’re working your quadriceps, hamstring and gluteus muscles. It then sends that data to a computer for analysis. Although the skintight shorts are being marketed to athletes and coaches, they could be useful for the deskbound. The hope, according to Arto Pesola, who is working on an advanced version of the sensors, is that when you see data telling you just how inert you really are, you’ll be inspired to lead a less sedentary life.

4/ CLEAN HAIR, NO HANDS :
This 15-minute shampoo treatment begins when you lean your head back into a machine that looks like a sink at the salon. First it maps your scalp, then it shoots streams of warm water and foam shampoo from its 28 nozzles before 24 silicone “fingers” work up a lather. One conditioning mist, scalp massage and light blow-dry later, you’re done. Nathaniel Penn
10/ DOCTOR ON BOARD :
Your car is already able to call for help when an accident occurs, but within a few years, it’ll tip paramedics off to probable injuries too. E.M.T.’s would know the likelihood of internal bleeding or traumatic head injury, for example, before arriving on the scene, which would help them decide whether to move you to a Level 1 trauma center or a standard emergency room. Researchers at the University of Michigan International Center for Automotive Medicine have created the predictive models by cross-referencing the crash data provided by sensors on cars, like speed and location of impact, with 3-D scans of accident victims.
