A new type of solar sail has been woven by a team of scientists in Finland. The spiderweb-like sail is designed to catch the wind of ionised gas that blows from the Sun, carrying spacecraft to the outer reaches of the solar system, or letting them tack back and forth through the asteroid belt on exploration or mining missions.

This is an amazing breakthrough and one that has practical applications

Article: Simple ‘superlens’ sharpens focusing power

A simple-to-make “superlens” can focus 10 times more sharply than a conventional lens. It could shrink the size of features on computer chips, or help power gadgets without wires.

No matter how powerful a conventional lens, it cannot focus light down to more than about half its wavelength, the “diffraction limit“. This limits the amount of data that can be stored on a CD, and the size of features on computer chips. Continue reading »
