Arizona State University builds protein beam injector; contributes nanocrystalsUnraveling the molecular basis of life is an age-old quest of humanity. A breakthrough towards this goal was reported in a pair of studies published Feb. 3 in the scientific journal Nature, detailing a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals that are so small that they are not even visible under the microscope. A tiny aerojet nozzle provides a...

The National Institute of Standards and Technology (NIST) has issued a new ruler, and even for an organization that routinely deals in superlatives, it sets some records. Designed to be the most accurate commercially available "meter stick" for the nano world, the new measuring tool"”a calibration standard for X-ray diffraction"”boasts uncertainties below a femtometer. That's 0.000 000 000 000 001 meter, or roughly the size of a neutron. The new ruler is in the form of a thin,...

Scientists at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory have developed a fast and efficient way to determine the structure of proteins, shortening a process that often takes years into a matter of days. The high-throughput protein pipeline could allow scientists to expedite the development of biofuels, decipher how extremophiles thrive in conditions that kill most organisms, and better understand how proteins carry out life's vital functions. The technique...

A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter). Optical and electronic properties of small assemblages of atoms called quantum dots depend upon their electronic structure "“ not just what's on the surface, but also what's inside. While scientists can calculate the...

Excavations carried out at the 14th Century city wall of Granada have unearthed a brick kiln located next to stratified layers of bones and ashes. According to researchers from the University of Granada (UGR), this in situ evidence suggests that this kiln was used to manufacture a coating for the wall, which incorporated powder made from burnt bones. "The bricks from the kiln that was discovered showed evidence of melting (blackened surfaces and small bubbles), which indicates that...
