Researchers say structures may be used in windows to wick away moisture.
In 2012, a team of researchers in London imaged, for the first time, the structure of the DNA double helix. James Watson and Francis Crick discovered DNA 60 years ago by laboriously studying x-ray diffraction images of millions of DNA molecules. However, Dr. Bart Hoogenboom and Dr. Carl Leung used atomic force microscopy (AFM) to directly “feel” the molecule’s structure in a fraction of the time.
Traditional lithography is based on a simple principle: Oil and water don’t mix. The method, first developed by an actor in Bavaria in 1796, used a smooth piece of limestone on which an oil-based image was drawn and overlayed with gum arabic in water. During printing, the ink was attracted to the oil, and was repelled by the gum.

There’s a new wave of sound on the horizon carrying with it a broad scope of tantalizing potential applications, including advanced ultrasonic imaging and therapy, and acoustic cloaking, levitation and particle manipulation. Researchers with Lawrence Berkeley National Laboratory have developed a technique for generating acoustic bottles in open air that can bend the paths of sound waves along prescribed convex trajectories.
A flu virus acts like a Trojan horse as it attacks and infects host cells. Scientists at Rice Univ. and Baylor College of Medicine have acquired a clearer view of the well-hidden mechanism involved. Their computer simulations may lead to new strategies to stop influenza, perhaps even a one-size-fits-all vaccine.
China's first emperor ordered the building of a glorious underground palace complex, mirroring his imperial capital, that would last for an eternity. Protecting this underworld palace was his imperial guard, cast in terracotta. Efforts to preserve the 1974 archaeological find have been hampered by failures to pinpoint the binding material used in applying pigments to the soldiers. Mass spectrometry studies have recently solved this mystery.
Sun, wind and other renewable energy sources could make up a larger portion of the electricity America consumes if better batteries could be built to store the intermittent energy for cloudy, windless days. Now a new material could allow more utilities to store large amounts of renewable energy and make the nation's power system more reliable and resilient.
Aerosols, tiny particles in the atmosphere, play a significant role in Earth's climate, scattering and absorbing incoming sunlight and affecting the formation and properties of clouds. Currently, the effect that these aerosols have on clouds represents the largest uncertainty among all influences on climate change.
