Most breast cancer patients with more than 10 nodes that are affected by the cancer have a poor prognosis, yet some survive long-term. Physicians now believe that certain genes in the breast cancer tissue, removed at diagnosis, can help them predict which patients will survive.
With this information, doctors can recommend the most appropriate therapy for an individual patient, for example sparing a woman with a poor prognosis the rigors that accompany aggressive chemotherapy, and enabling her to receive novel treatments that might work, according to Dr. Melody Cobleigh, oncologist, professor of medicine and director of the Comprehensive Breast Center at Rush-Presbyterian-St. Lukes Medical Center in Chicago.
Cobleigh presented her research results on May 31 at the American Society of Clinical Oncology Annual Meeting in Chicago. Until now, such studies could only be performed on recently biopsied tissue that would then be frozen for preservation. Routine handling of cancer specimens does not involve freezing. Cobleigh and colleagues at Genomic Health examined the breast cancer tissue of 79 patients who had been treated at Rush between 1979 and 1999 and whose tissues had been processed in the usual manner (formalin-fixed and paraffin-embedded). The patients had been followed for a median of 15 years.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
