NeverWet: The end of the mustard stain?
Prone to spilling on yourself? A new spray-on substance called NeverWet may just be for you. The industrial liquid repellant is a few years old, but a consumer version hits shelves this week. Click on the video below to see it in action.
And tell us, would you use NeverWet and what for? Marketplace Tech host Ben Johnson suggests turning tuxedo pants into a really stylish swimsuit.
Robo nurse, coming to a hospital near you?
Medical machinery has come a long way -- and now robots are getting in on the action. Click on the video below to watch a robotic nurse bathe a bed-ridden patient autonomously.
It may move slow, but it seems to do the job. Healthcare Robotics, the company who makes the robot, reports its efficacy as such:
In our experiments, the robot removed most of the debris (>96%) on four parts of the limbs. In addition, the robot performed the wiping task using relatively low force.
The 'What if' problem of government surveillance
Count me in the camp of people who aren't worried about the NSA dragging me away because of communications I've had on the phone or online. But there's one big problem with secret government surveillance of data on U.S. citizens: the "what if" problem. While our current political system doesn't seem to punish people recklessly for speaking up and excercising free speech, that could always change. And that's the heart of the issue, to me. We can't know what the future holds for our political system, and because of that, we need to be vigilant in protecting our First Ammendment rights.

Scientists snap first ever pictures of molecules before and after reaction
Using a new state-of-the-art atomic force microscope, scientists at UC Berkeley were able to capture the first images of a molecule just before and after it reacts. The images show the molecule's structure in detail, even the bonds connecting atoms. Until now, scientists have only been able to infer this type of information.
The series of images on the left side (labeled A) show the molecule before, while the images on the right (labeled B) display the after.
Non-contact atomic force microscope (nc-AFM) images (center) of a molecule before and after a reaction improve immensely over images (top) from a scanning tunneling microscope and look just like the classic molecular structure diagrams (bottom). Source: UC Berkeley News Center.
Put a GIF in your bike wheel
If you love GIF animations and love to cycle safely, here's a new crowd-funded product you'll love: The Monkey Light Pro. The bike accessory uses LED light bars that fit in the spokes of your wheel to create a rideable display system. Kind of ridiculous, but kind of great, too?
Happy Birthday Robert Moog!
Correction: The original entry referred to Robert Moog as still alive. He died in 2005.
Robert Moog would have been 79 today. He invented the analogue Moog synthesizer that first gained notoriety at a performance during the 1967 Monterey International Pop Festival. It's been used by keyboard lovers like Stevie Wonder ever since.
