Bionic Coating for Fuel-Efficient Ships

The water fern salvinia molesta is extremely hydrophobic, surrounding itself by a flimsy skirt of air that prevents the plant from coming into contact with liquid. This inconspicuous plant could allow ships to have a 10 percent decrease in fuel consumption.

Should broadband providers be required to provide network neutrality?

This week's question concerns "net neutrality" -- providing equal treatment to all Internet traffic flowing over networks. Supporters of net neutrality argue that a policy is necessary to prevent providers from favoring or discriminating against certain Web sites and online services; however, broadband providers contend that they should be able to sell premium services and manage their systems to prevent certain applications from sucking up capacity.

What do you think? Should broadband providers be required to provide network neutrality?

Electrical Current Stemming From Algae

Stanford scientists have harnessed a tiny electrical current from algae cells. They found it at the very source of energy production – photosynthesis - and it may be the first step toward generating high-efficiency bioelectricity that doesn't give off carbon dioxide as a byproduct.

Moving Toward a Carbon-based Solar Cell

To make large sheets of carbon available for light collection, Indiana University Bloomington chemists have attached what amounts to a 3D bramble patch to each side of the carbon sheet. The scientists say they were able to dissolve sheets containing as many as 168 carbon atoms, which is a first.
