Currently, the best way to predict whether a breast cancer is likely to recur is to determine whether tumor cells have invaded the lymph nodes near the breast. But new research from the Stanford University School of Medicine suggests that looking at the immune cells in those lymph nodes - instead of the tumor cells - will yield a more accurate forecast. The finding could help clinicians determine which cancers to treat more aggressively to ensure the cancer goes away and doesnt come back.
"Immune changes in the lymph node almost perfectly predict clinical outcome, much better than any other prognostic factor that is available today," said Peter P. Lee, MD, assistant professor of medicine and the senior author of the paper detailing the findings in the Sept. 6 advance online edition of Public Library of Science-Medicine.
In samples of breast cancer patients lymph nodes, Lee and his colleagues identified unique patterns of immune cells. When the researchers compared the immune profiles to whether a patients cancer returned within five years, they could divide the patients into two groups. The group with what Lee termed a "favorable" immune profile had an 85 to 90 percent chance of being disease-free after five years. The group with an "unfavorable" immune profile had less than a 15 percent chance.

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.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

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...
