In trying to bring brain-like (neuromorphic) computing closer to reality, researchers have been working on the development of memory resistors, or memristors, which are resistors in a circuit that 'remember' their state even if you lose power. Today, most computers use random access memory (RAM), which moves very quickly as a user works but does [...]
The recent rise in the value of BitCoin, whether a bubble or not, has stimulated great interest in the blockchain, and a recent opinion piece in the New York Times places it in the context of falling confidence in institutions and governments. From “The Bitcoin Boom: In Code We Trust” by Tim Wu, Dec. 18, [...]
A research team led by a scientist from the U.S. Department of Energy’s Ames Laboratory has demonstrated for the first time that the magnetic fields of bacterial cells and magnetic nano-objects in liquid can be studied at high resolution using electron microscopy. This proof-of-principle capability allows first-hand observation of liquid environment phenomena, and has the [...]
Antibodies are indispensable in biological research and medical diagnostics. However, their production is time-consuming, expensive, and requires the use of many animals. Scientists at the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, have now developed so-called secondary nanobodies that can replace the most-used antibodies and may drastically reduce the number of animals in [...]
Cells communicate with each other through a number of different mechanisms. Some of these mechanisms are well-known: in animals, for example, predatory threats can drive the release of norepinephrine, a hormone that travels through the bloodstream and triggers heart and muscle cells to initiate a “fight-or-flight” response. A far less familiar mode of cellular transport [...]
Imagine that instead of switching on a lamp when it gets dark, you could read by the light of a glowing plant on your desk. MIT engineers have taken a critical first step toward making that vision a reality. By embedding specialized nanoparticles into the leaves of a watercress plant, they induced the plants to [...]
Features Explores and presents innovative nanotechnological and biomimetically derived strategies in the design of potential nanomedical devices and their constituents Contains several post-chapter Proposed Research Tasking Lists to facilitate the further investigation and potential development of specific nanomedical capacities Includes eight chapters contributed by some of the leading experts in nanotechnology, nanomaterials, and [...]
Scientists have created a method to detect tiny tumors and track their spread using light-emitting nanoparticles. The technology could lead to earlier cancer detection, more precise treatments, and even improvement in patient cure rates and survival times. “We’ve always had this dream that we can track the progression of cancer in real time, and that’s [...]
Oregon State University scientists have developed a nanomedicine platform for cancer that can help doctors know which tissue to cut out as well as kill any malignant cells that can't be surgically removed. The platform allows for greater precision and thoroughness in cancer treatment. Here's how it works: Nanoparticles tightly loaded with a dye compound [...]
From an article by Kyree Leary at futurism.com: In 1953, a pair of scientists named James D. Watson and Francis H.C. Crick — with help from the data supplied by the research of another scientist, Rosalind Franklin, — successfully modeled the structure of DNA for the first time. Since then, whenever we think of DNA, we usually imagine the [...]
