May lead to sharper picture of human genome as well
Dana-Farber Cancer Institute scientists have used a powerful gene-mapping technique to produce the clearest picture yet of all the genes of an animal – the microscopic worm Caenorhabditis elegans (better known as C. elegans). Scientists believe the same technique may be used to bring the current, somewhat blurry picture of the human genome into sharper focus.
The study, which will be posted on the Nature Genetics website (
For the first time, researchers are characterizing the molecular processes that turn brain cancer deadly, and their work may result in a diagnostic test that can predict patient survival.
The research, by scientists at The University of Texas M. D. Anderson Cancer Center demonstrates that degree of loss of a crucial tumor suppressor gene, the AP-2( transcription factor, correlates with progression of different human gliomas.
For example, researchers found that normal brain tissue,
Researchers report that in laboratory animals, the combination of radiation and the anti-angiogenic drug, endostatin, appears to work synergistically together to stop development of new blood vessels that seek to grow and nourish damaged tumors.
Researchers at The University of Texas M. D. Anderson Cancer Center found that the regrowth of new blood vessels was reduced five-fold in mice with implanted squamous cell cancer treated with radiation and endostatin compared to diseased mice that had ra
When Gerald A. Miller first saw the experimental results from the Thomas Jefferson National Accelerator Facility, he was pretty sure they couldnt be right. If they were, it meant that some long-held notions about the proton, a primary building block of atoms, were wrong.
But in time, the findings proved to be right, and led physicists to the conclusion that protons arent always spherically shaped, like a basketball.
“Some physicists thought they did the experiment wron
This symmetry violation makes hydrogen possible, a requirement for life
Scientists at the Indiana University Cyclotron Facility in Bloomington have made the first unambiguous detection of a rare process, the fusion of two nuclei of heavy hydrogen to form a nucleus of helium and an uncharged pion. The pion is one of the subatomic particles responsible for the strong force that holds every nucleus together. The achievement will be announced Saturday (April 5) at the meeting of the Amer
Two billion years ago, in a far-away galaxy, a giant star exploded, releasing almost unbelievable amounts of energy as it collapsed to a black hole. The light from that explosion finally reached Earth at 6:37 a.m. EST on March 29, igniting a frenzy of activity among astronomers worldwide. This phenomenon has been called a hypernova, playing on the name of the supernova events that mark the violent end of massive stars.
