Institute for Systems Biology Symposium Addresses Need for Better Computational Tools

... Grid is enabling ISB researchers to predict three dimensional structures, which are more highly conserved than one dimensional structures. Understanding three dimensional structures allow researchers to identify the presumptive...

Major advance made on DNA structure

...tarting to see what the genome looks like in three dimensional reality, not just what the sequence of genes is," Ho said. "DNA is much more than just a string of letters, it's an actual structure that we have to explore if we ever hope to understand biological function. This is a significant step forward, a mile...

Clues to breast cancer hidden inside stem cells

...on immortalised these cells and grew them in three dimensional matrix that mimics the real, living tissue. Biologists have long relied on 2-dimensional cell cultures as the basic tool of their trade. But there is a big difference between a flat layer of cells and culturing cells in three-dimensions. The Icelandi...

Scientists make first step towards 'holy grail' of crystallography

...h converts materials, such as proteins, into three dimensional crystals, thus enabling their atomic structure to be studied. The three dimensional structure of the crystals indicates the proteins function, and from this, researchers hope to be abl...

Brain-computer link lets paralyzed patients convert thoughts into actions

...ers to convert patterns of neural spikes into two- dimensional commands. "Training patients to move things with their minds is different with each patient," said Maryam Saleh, who worked with the first two patients as a Cyberkinetics technician and is now a doctoral student in Hatsopoulos's Chicago lab.

Danish researches solve virus puzzle

... a tendency to curl up into 'pseudoknots', a three dimensional structure. When the ribosome walking along an RNA encounters a pseudoknot it needs to unravel the pseudoknot before it can proceed. Question is, how does it do that? Lene Oddershede at the Niels Bohr Institute, University of Copenhagen has developed ...
