Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products. In a paper published in The Journal of Physical Chemistry Letters, a team led by Pratul Agarwal of the Department of Energy's Oak Ridge National Laboratory described a process that aims to improve upon nature - and it happens in the blink of an eye. "When light enters the eye and hits the...

A quicker and cheaper technique to scan molecular databases developed at the Department of Energy's Oak Ridge National Laboratory could put scientists on the fast track to developing new drug treatments. A team led by Jerome Baudry of the University of Tennessee-ORNL Center for Molecular Biophysics adapted a widely used existing software to allow supercomputers such as ORNL's Jaguar to sift through immense molecular databases and pinpoint chemical compounds as potential drug candidates. The...

OAK RIDGE, Tenn., March 17 /PRNewswire-USNewswire/ -- Two far-reaching projects announced in recent days further bolster the Knoxville-Oak Ridge Innovation Valley's claim as a world-class center of research, entrepreneurial activities and high tech jobs. Work begins this week on the 188-acre Cherokee Farms high tech park on the University of Tennessee Knoxville campus. The first building planned for the park, the Joint Institute for Materials Science, is one of several cooperative ventures...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'karpos', fruit.
