BlueMatter
Date added: 2009-11-18
BlueMatter, a new algorithm created in collaboration with Stanford University, exploits the Blue Gene supercomputing architecture in order to noninvasively measure and map the connections between all cortical and sub-cortical locations within the human brain using magnetic resonance diffusion weighted imaging. Mapping the wiring diagram of the brain is crucial to untangling its vast communication network and understanding how it represents and processes information.

IBM Visual Editor
Date added: 2009-10-26
IBM Researchers are making Web sites more readable on the small screens of mobile devices. IBM computer scientists borrowed technology that the company originally developed for the visually impaired. Employing arrows and drag-and-drop capabilities, IBM's visual editor proof-of-concept simplifies the process of presenting content in the correct order.

President Obama recognizes IBM with the National Medal of Technology and Innovation
Date added: 2009-10-07
President Obama recognizes IBM with the 2008 National Medal of Technology and Innovation for the IBM Blue Gene family of supercomputers. The National Medal of Technology and Innovation is the United States' most prestigious award given to leading innovators for technological achievement. IBM CEO Sam Palmisano is shown here accepting the award on IBM's behalf on Wednesday, Oct. 7, 2009, in the East Room of the White House in Washington, DC. IBM Blue Gene is one of the world's fastest, most energy-efficient computers -- one that is helping to solve humanity's most stubborn challenges in science, medicine, mathematics, astronomy, defense, finance, and other crucial disciplines.

Schematics of the DNA transistor operation for the control of the translocation of a DNA through a nanopore
Date added: 2009-10-06
A membrane containing the nanopore, funtionalized with metal contacts (orange) separated by dielectric materials (lime), devides a reservoir into a top part containing an ionic solution with a high concentration of single stranded DNA, and a bottom part, where the DNA will be translocated to. The DNA on the top reservoir is induced to go to the bottom reservoir by the action of a biasing voltage. In the absence of anything else, the DNA would translocate through the pore at a speed of several million bases per second. To control the passage of DNA trhough the nano-hole, voltages of appropriate polarity (not shown) are applied to the metal contacts inside the pore, which create an internal electric field that trap the DNA. By alternating the trapping voltages applied to the metal contacts, the DNA can be made ratchet from the top to the bottom reservoirs in a controlled way.

A cross section of IBM's DNA Transistor
Date added: 2009-10-06
A cross section of IBM's DNA Transistor simulated on Blue Gene supercomputer showing a single stranded DNA moving in the midst of (invisible) water molecules through the nanopore. The DNA molecule, at the center of the pore, contain the bases A, C, G and T, that code of biological information necessary for life.
