...evitating droplets and crystals and to control the orientation of the levitating crystals. The droplets used were as small as bacteria or 100 times smaller than a human hair, and up to one billion times smaller in volume than has been demonstrated by conventional methods. Their work was recently published in Ap...Found: Missing sequence of the human Y chromosome
...ion of a 13-year effort to elucidate the order and orientation of 2.85 billion basepairs that comprise the human genome. The high-quality sequence spanned more than 99% of the euchromatic (gene-containing) portion of the genome with an accuracy of 99.999%, but despite this accomplishment, substantial sections o...NSBRI news: Bone-quality assessment tool for space and Earth

While focusing on space health issues, the Institute will quickly transfer solutions to Earth patients suffering from similar conditions. The NSBRI, funded by NASA, is a consortium of institutions studying the health...Purdue researchers align nanotubes to improve artificial joints
...nanofibers are aligned in the same direction. This orientation is similar to the way collagen and natural ceramic crystals, called hydroxyapatite, are aligned in bone, said Thomas Webster, an assistant professor of biomedical engineering at Purdue. Findings were presented at two recent scientific conferences in ...Story tips from the Department of Energy's Oak Ridge National Laboratory, October 2004
...can control the length, diameter, shape, position, orientation and chemical composition of the nanofibers. The nanofibers can be arranged to create tiny fluid-filled membrane structures that enable rapid diffusion-based mixing. The silicon-based fabrication techniques allow integration with electronic devices. "...
