Keeping It Simple

I’m sure many engineers would agree that the worst part of the whole design process is prototyping a new printed circuit board. It’s like trying to assemble a jigsaw puzzle in the midst of a scavenger hunt.

The problem with prototyping is that it’s more of an art than a science. Unfortunately engineers are, by...

Premature Protection

Even after nine months soaking in the watery, warm environment of a womb, a newborn’s skin is smooth – unlike an adult’s in the bath. A natural, protective cream called Vernix caseosa (VC) covers the fetus and the newborn, aiding in the growth of skin. VC provides "waterproofing" in utero, allowing skin to grow in wet...

Counting Calories While Asleep

As someone who’s been thin most of his life, I’ve never felt the need to monitor my caloric consumption. But go to any fitness club or jogging trail and you’ll see lots of sweating bodies intently eyeing pedometers to see how many steps they’ve taken and how many calories they’re burning. Now, a group of...
