Nanocatalysts That Remotely Control Chemical Reactions Inside Living Cells

The enzymes responsible for catalytic reactions in our body's biological reactions are difficult to use for diagnosis or treatment as they react only to certain molecules or have low stability. Many ...

New Science Behind Algae-Based Flip-Flops

Sustainable flip-flops: A team of researchers has formulated polyurethane foams made from algae oil to meet commercial specifications for midsole shoes and the foot-bed of ...

Why Shaving Dulls Even the Sharpest of Razors

Engineers have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair -- a material that is 50 times softer than the blade itself. They found ...

Drivers Respond to Pre-Crash Warnings With Levels of Attentive 'Gaze'

Engineers conducted open road testing of three collision avoidance systems and demonstrated that a drivers' visual behavior in response to an alert generated from a collision avoidance system can be ...
