Despite the common belief in the oncology community that cancer research and treatment have focused on breast tumors that are estrogen receptor (ER)-positive, a researcher from The University of Texas M. D. Anderson Cancer Center maintains that clinicians have made "enormous strides" in treating patients with tumors that are ER-negative.
In a presentation at the annual meeting of the San Antonio Breast Cancer Symposium, Donald Berry, Ph.D., a professor and chair of the Department of Biostatistics and Applied Mathematics, looked at decades of breast cancer clinical trial experience and found that "the benefit of chemotherapy advances over the last 20 years to ER-negative patients has been surprisingly dramatic."
In examining the impact of chemotherapy treatment of node-positive breast cancer in three national clinical trials, which enrolled more than 6,000 patients cumulatively, Berry found that chemotherapy has reduced the risk of death in ER-negative patients by 56 percent. "The absolute benefit has been similarly impressive, especially in comparison with the corresponding absolute benefit of chemotherapy to ER-positive patients," he says.

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...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
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...
