As Sticky as a Gecko ... but Ten Times Stronger!
The gecko's amazing ability to stick to surfaces and walk up walls has inspired many researchers to manufacture materials that mimic the special surface of a gecko's foot. The secret behind the gecko's ability to stick so well is a forest of pillars at the micro-/nano-scale on the underside of the gecko's foot. Because there are so many pillars so close together, they are held tightly to the surface the gecko is walking on by a molecular force called the Van der Waals force. This relatively ...

U.S.-Led, International AGAP Team Poised to Probe One of Antarctica's Last Unexplored Places
A U.S.-led, multinational team of scientists from six nations will pierce the mysteries of one of the globe's last major unexplored places this month. Using sophisticated airborne radar and other Information Age tools and techniques, the scientists will virtually "peel away" more than four kilometers (2.5 miles) of ice covering an Antarctic mountain range that rivals the Alps in elevation, and which current scientific knowledge suggests shouldn't be there at all.
What ...
