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 couldn’t 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 aren’t 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.

With two telescopes separated by about 110 degrees longitude, the Roboti

Scientists from the University of Minnesota demonstrated yields of corn and soybeans were only minimally reduced when organic production practices were utilized as compared with conventional production practices. After factoring in production costs, net returns between the two production strategies were equivalent.

More than 80% of corn and soybeans produced in the United States is grown in the Midwest, the vast majority with conventional production practices in a corn-soybean rotation requ
