Researchers at the Breast Care Center at Baylor College of Medicine and The Methodist Hospital have developed a new test to predict which breast cancer tumors will respond to chemotherapy, potentially reducing unnecessary treatment for women with breast cancer, according to data presented at the American Society of Clinical Oncology annual meeting in Chicago.
Using novel DNA array technology, the study identified differences in the gene patterns from tumor samples that predict which patients would respond to treatment with the chemotherapy docetaxel, marketed under the brand name Taxotere by Aventis.
After studying pretreatment biopsies from 24 patients and their genes after treatment, results show that tumors responding to Taxotere show a different pattern than tumors that had not responded to drug therapy. In the study, 88 percent of the genes were correctly classified, said Dr. Jenny Chang, an assistant professor of medicine at Baylor. This study marks the first time microarray technology has been used to study breast cancer tumor response to a chemotherapeutic agent.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
