Stain Free Materials with Nanotechnology

Always looking for ways to become a laundry ninja, I happened across nanoparticle research being done by Dr. Anish Tuteja, Assistant Professor of Materials Science and Engineering and Arun Kota, PhD, at the University of Michigan on coatings that not only resist stains and liquids (e.g., honey, syrup, sulfuric acid, etc.) but actually bounce off it. 

The new coatings could be applied to waterproof paints that reduce drag on ships, phones to eliminate any and all fingerprints, as well as windshields and ski goggles that would never spot. Moreover, the coating could lead to breathable garments that would protect soldiers and scientists from chemicals and microorganisms. Go science!

Checking Out A Mars Comet Flyby

We tend to forget how much space hardware we have in our cosmic quiver. Now these space science assets are gearing up for a once-in-a-lifetime comet (C/2013 A1) flyby of Mars on October 19, 2014. The comet, also called Siding Spring, will pass within 87,000 miles (139,500 km) of our neighboring planet. This may not seem like a near miss, but to put it into perspective, it is less than half the distance to our moon from Earth. 

NASA expects Siding Spring (coming from the Oort Cloud 5,000 - 100,000 astronomical units away and thought to be left from the formation of the solar system) to pass by Mars with little problem, but the debris trail that accompanies comets may be a different story. [NASA rovers Curiosity and Opportunity should be fine and checking out the visitor.] Time will tell.

In any event, we Earthlings and our NASA instrumentation/satellites will have front row seats to the action. Go science!
