coffee

One of the most difficult aspects of science is conceptualizing some of the unbelievably large, (and unimaginably small) numbers that routinely pop up. The Universe is 5.5 x 10^23 miles across. A human hair is about 7 x 10^-4 inches across. Hard to imagine how things like cells, proteins and atoms all relate to one another. Now, at least for the very small things, the University of Utah has developed a fun little Flash graphic to make sense of all of it.

It's an everyday irritation: Your coffee's too hot to sip, so you dump in some milk and set it aside for a minute while you answer just one email. Turn back to the coffee, and now it's tepid and unappetizing.

The geniuses at the Fraunhofer Institute, just like us regular folks, are fed up with such nonsense. Unlike us, though, they're German engineers, so they've created the Perfect Coffee Mug to extirpate imperfect coffee once and for all.

Anyone who's ever spilled a hot beverage in his or her lap will be happy to hear that chemists at the University of Minnesota have announced a scaldproof fabric.

Water-resistant fabric, of course, has already existed for some time -- but its impermeability applies only to cool liquids. Hot coffee, scalding soup, and other liquids above a certain temperature, on the other hand, seep right through water-resistant cloth.

Even though this 'bot was dutifully programmed for each admittedly complex step--far from autonomous--we can dream, can't we, of a cute attendant chugging away with our espresso kit while we read the morning news?

Stumped at the café? Go for a mocha.

According to new research, the tasty beverage provides a double-whammy of health benefits: chocolate may slow cancer growth, and java could help you live longer. The good news about chocolate comes from scientists at Georgetown University Medical Center, who found that a synthetic chemical that is similar to a compound present in cocoa beans slows the growth of colon cancer by 50 percent.

Though caffeine is always ripe for scientific inquiry; in recent months, researchers have grown seemingly obsessed with the drug. So, in the midst of stories about coffee reducing the risk of diabetes and the proper way to optimize your caffeine intake, a study analyzing the role of that beloved aroma was bound to appear sooner or later. And lo and behold, an international team of scientists has done just that by exposing sleep-deprived rats to the sweet smell of java and recording the results.

As a species, we´ve hit the bedtime barrier. You can eat at your desk, socialize in the break room, and answer text messages on a date, but sooner or later, you´re going to have to sleep. â€After 18, 19 hours awake, your brain function starts to fail,†says Dallas, Texas, sleep-medicine specialist Andrew O. Jamieson. Coffee might keep you up, â€but you´re not going to be focused.â€
