Scientists report success in boosting the ability of zinc oxide solar cells to absorb visible light simply by applying a blended mixture of various off-the-shelf dyes commonly used in food and medical industries -- in a soak-then-dry procedure not unlike that used to color a tee-shirt in a home washing machine.

A new imaging system using six different wavelengths to illuminate the interior of the eyeball (ocular fundus) may pave the way for doctors to easily screen patients for common diseases of the eye, such as age-related macular degeneration and diabetic retinopathy.
IceCube neutrino observatory nears completion

In December 2010, IceCube -- the world's first kilometer-scale neutrino observatory, located beneath the Antarctic ice -- will finally be completed after two decades of planning. A new article provides a comprehensive description of the observatory, its instrumentation, and its scientific mission
Silicon oxide circuits break barrier: Nanocrystal conductors could lead to massive, robust 3-D storage

Scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic manufacturing techniques and promises to extend the limits of miniaturization subject to Moore's Law.
NASA and ATK successfully test five-segment solid rocket motor

With a loud roar and mighty column of flame, NASA and ATK Aerospace Systems successfully completed a two-minute, full-scale test of the largest and most powerful solid rocket motor designed for flight. The motor is potentially transferable to future heavy-lift launch vehicle designs.
High-speed filter uses electrified nanostructures to purify water at low cost
16:25 31-08-2010; source: www.sciencedaily.com
Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.

Quotes:
Perfect as the wing of a bird may be, it will never enable the bird to fly if unsupported by the air. Facts are the air of science. Without them a man of science can never rise.
The angry man always thinks he can do more than he can.
The good or ill of a man lies within his own will.
