Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. Tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading.
A recent study at the U.S. Department of Energy's Argonne National Laboratory has called into question the existence of silicene, thought to be one of the world's newest and hottest two-dimensional nanomaterials.
Forscher vom Fraunhofer-Institut für Werkstoffmechanik IWM in Freiburg haben nun mit einer aufwendigen Computersimulation gezeigt, dass nanokristalline Schichten die Reibung zwar reduzieren, dass es aber dennoch zum Verschleiss kommen kann.
A new phase of matter known as topological insulators, until recently known only for esoteric quantum-mechanical properties, might have a practical use in controlling magnetic memory and logic devices.
Adding to the growing fundamental understanding of the machinery of muscle cells, a group of biophysicists describe how actin filaments are stabilized at one of their ends to form a basic muscle structure called the sarcomere.
Scientists have developed a new nanoscale agent for imaging the gastrointestinal (GI) tract. This safe, noninvasive method for assessing the function and properties of the GI tract in real time could lead to better diagnosis and treatment of gut diseases.
