Malignant melanoma is the most aggressive type of skin cancer. In more than 50 percent of affected patients a particular mutation plays an important role. As the life span of the patients carrying the mutation can be significantly extended by novel drugs, it is very important to identify those reliably. For identification, researchers from the University of Basel and the Ludwig Institute for Cancer Research in Lausanne have developed a novel nanosensor method.
This work represents the first step towards creating exotic mechanical quantum states. For example, the transfer makes it possible to create a state in which the resonator simultaneously vibrates and doesn't vibrate.
Magnetic resonance imaging (MRI) reveals details of living tissues, diseased organs and tumors inside the body without x-rays or surgery. What if the same technology could peer down to the level of atoms?
Stanford study is the first to demonstrate that sophisticated, engineered light resonators can be inserted inside cells without damaging the host. The researchers say it marks a new age in which tiny lasers and light-emitting diodes yield new avenues in the study and influence of living cells.
Chemists at Boston College have designed a new class of catalysts triggered by the charge of a single proton. The simple organic molecules offer a sustainable and highly efficient platform for chemical reactions that produce sets of molecules crucial to advances in medicine and the life sciences.
Chemical engineers at Johns Hopkins University have developed self-assembling particles that are inspired by origami, the traditional Japanese art of folding paper into complex three-dimensional shapes. A new article demonstrates the fabrication and folding of these particles.
Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable electronics, even a listening device hiding in a prosthetic toe, without knowing where it is. While these applications remain only dreams, researchers at the University of Maryland have come up with a sci-fi seeming technology that one day could make them real.
University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their edges, but act as an insulator inside. These materials, called organic topological insulators, could shuttle information at the speed of light in quantum computers and other high-speed electronic devices.
A new review looks at the effects of the orientation of a graphene sheet, the edge structure of carbon nanofibers, and different surface functional groups on proton affinity, interactions with metal nanoparticles, and electronic modification of these structures, together with their catalytic consequences.
As part of an international study, a team of researchers has adapted some of these natural mechanisms to detect specific molecules such as cocaine more accurately and quickly. Their work may greatly facilitate the rapid screening - less than five minutes - of many drugs, infectious diseases, and cancers.
