University of Texas at Dallas researchers and their colleagues at other institutions are investigating ways to harvest energy from such diverse sources as mechanical vibrations, wasted heat, radio waves, light and even movements of the human body.
Infectious diseases such as malaria and syphilis can be diagnosed rapidly and reliably in the field by using a simple test developed by Canadian scientists. The test is based on the use of DNAzymes and gold nanoparticles.
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.
