When a roadside bomb or other explosive device goes off, it hits everything nearby with an extreme blast of pressure. Almost simultaneously comes a heat--more than 1,000 degrees Fahrenheit--that's hot enough to cook skin. Presented today at a meeting of the American Chemical Society, a new invention will try to counteract that, and do it through a technology that's already been used for hundreds of years: camouflage paint.
As we approach the Mars rover Curiosity’s landing Sunday night, we’re having a lot of fun seeing all the promotions — there are all kinds of videos, museum exhibits and road shows to help explain what the newest interplanetary explorer will do. Below is a great new one from the American Chemical Society.
Think a trip to the pharmacy is overwhelming? Try this: One million billion billion billion billion billion billion. That’s a 1 with 60 zeroes after it. That’s the number of potential new medicines that could still be made, according to a new study. It may be more than the number of stars in the universe.
Next time you take your temperature, maybe think twice about its accuracy. Despite what the mercury says, not all of your cells are really at 98.6 degrees, scientists reported in a new study. Using nanoscale thermometers, researchers have shown for the first time that living cells can exist at different temperatures. Busy sections are warmer, and less-active ones are cooler.
Foodies want to know everything about their animal-based dishes these days — where the meat came from, what it ate, what its name was. OK, maybe not that last part. But there is a big difference between industrial cattle farms and grass-fed meat — both in price and in nutritional considerations.
We're already making great strides at pulling electricity from the motion of the air and from the photons that stream through it, but what about pulling electric charges right out of the air itself? Researchers have solved a mystery about how electricity forms in the atmosphere, and in doing so may have found a way to pull electricity right out of the air.
Wouldn't it be convenient if Red Bull could recharge your phone just as it recharges you? Researchers at the National Meeting of the American Chemical Society today revealed the creation of a new breed of battery-like device that's more like the mitochondria that fuel biological cells than the anode-cathode batteries that charge our devices. As such, it could power our cell phones or other portable electronics with sugary drinks or other energy-storing media like vegetable oils.
