Interviews: Ask Former Director of JPL Edward Stone About Space Exploration

jorge_salazar Interstellar exploration (58 comments)

In 2016 the Voyager could become the first interstellar spacecraft. What does this mean to you, and are you hopeful that humans will see for themselves what's out there beyond our solar system space bubble?

Brain Cell Linker Dependence Shown by Supercomputer Simulations

jorge_salazar jorge_salazar writes  |  about 2 months ago

jorge_salazar (3562633) writes "Neuroscientists at Stony Brook University in New York teamed up with computational biophysicists at Florida State University and found that the function of a key brain cell receptor critically depends on a short polypeptide segment, which they call a linker, to function. Parkinson's disease, Alzheimer's disease, and a number of psychiatric disorders such as schizophrenia are associated with malfunctions of this brain receptor, called the NMDA (N-methyl-D-aspartate) receptor. Obama's $100 million BRAIN initiative promises to bring together more eclectic teams like this one to find new tools to map the human brain's billions of nerve cells, networks, and pathways in real time."

Mouth Bacteria Can Change Its Diet, Supercomputers Reveal

jorge_salazar jorge_salazar writes  |  about 3 months ago

jorge_salazar (3562633) writes "Bacteria outnumber the cells of your body by 10 to 1. Scientists are just beginning to understand what those bacteria do to promote or hinder health. By using supercomputers to reveal gene activity, scientists at the University of Texas at Austin found that bacteria under the gums "drastically" change their metabolism, or diet, depending on whether they're in a diseased or healthy area of the mouth. They say these findings could eventually lead to prevention or even reversal of 'bacterial-shift' diseases like diabetes, periodontitis, or Crohn's disease."

How a supercomputer beat the scrap heap and lived on to retire in Africa.

jorge_salazar jorge_salazar writes  |  about 4 months ago

jorge_salazar (3562633) writes "Pieces of the decommissioned Ranger supercomputer, 40 racks in all, were shipped to researchers in South Africa, Tanzania, and Botswana to help seed their supercomputing aspirations. They say they'll need supercomputers to solve their growing science problems in astronomy, bioinformatics, climate modeling and more. Ranger's own beginnings were described by the co-founder of Sun Microsystems as a "historic moment in petaflop computing.""

Alzheimer's and cancer link found, thanks to supercomputers

jorge_salazar jorge_salazar writes  |  about 7 months ago

jorge_salazar (3562633) writes "Cancer and Alzheimer's disease appear to have an inverse relationship. If you have one disease, you're less likely to get the other. Using supercomputers, Houston-based scientists have discovered a molecular-level missing link in the cell signaling pathways between the two dreaded diseases."
