'Crystal engineering' helps scientists solve 3-D protein structures

...and to produce computer-based tools for ultimately modeling the structure of any protein from its genetic spelling, or sequence. "This crystallization method has the potential to become a powerful new tool for structural biology and is a great example of the kind of innovation that the Protein Structure Initi...

New software developed at Rensselaer predicts promising ingredients for new drugs

...." Rensselaer researchers noted that predictive modeling is one of a new breed of drug discovery methods that marks a shift in industry practice--a shift away from cell-based assays performed in the lab toward math-based models calculated on the computer. "Our program allows researchers to 'crash te...

Secondary complications and restoration of function in SCI

...joint moments help control movement. Measuring and modeling the changes in passive properties following SCI will facilitate the development of better lower-limb musculoskeletal models. These models may aid in the development of enhanced neuroprostheses that use functional electrical stimulation to restore sta...

Statistical technique helps researchers gain more information from a single data run

...roblem at different scales," said Vidakovic. "The modeling should therefore be done at different scales because the materials are very different at the different scales." Analysis of genomic data, especially in the rapid determination of which genetic sequences are coding in which are not. Medical imaging,...
