Everything moves! But in a world dominated by electronic devices it is easy to forget that all measurements involve motion, whether it is motion of electrons through a transistor, or the simple displacement of a mechanical element. New EU-funded research suggests that quantum mechanics may hold the answer to when motion will die out.
University of Illinois engineers have developed a form of ultra-low-power digital memory that is faster and uses 100 times less energy than similar available memory. The technology could give future portable devices much longer battery life between charges.
Northwestern University researchers have developed a new switching device that takes quantum communication to a new level. The device is a practical step toward creating a network that takes advantage of the mysterious and powerful world of quantum mechanics.
When prostate cancer stem cells were enclosed in self-assembling nanomaterials made of peptides (SAP), the SAP stopped cancer stem cell colony formation and also stopped the division of cancer cells in laboratory cultures (in vitro). According to the international team of researchers who built and tested the nano-sized traps, the cancer cells grew and multiplied after they were "liberated" from their SAP prisons.
Researchers are developing computational models to predict the behaviour of nanomaterials in biological systems. Such predictions will allow researchers to streamline and prioritise the toxicological testing of nanomaterials.
The regions of the world see printed electronics differently. For example, the USA focuses on the military applications among others. East Asia wishes to use printed electronics to reinforce its dominance in electronic displays. Europe has interest in a very wide range of potential applications, with consumer packaged goods being just one of many applicational sectors prioritised.
Physicists have demonstrated an electromechanical circuit in which microwaves communicate with a vibrating mechanical component 1,000 times more vigorously than ever achieved before in similar experiments. This apparatus is a new tool for processing information and potentially could control the motion of a relatively large object at the smallest possible, or quantum, scale.
Tomorrow's nonvolatile memory devices - computer memory that can retain stored information even when not powered - will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance.
Using a novel microscopy method developed at the Institute, scientists from the Max Planck Institute for Medical Research in Heidelberg have now discovered that the distribution of the synapses between ganglion cells and interneurons follows highly specific rules. Only those dendrites that extend from the cell body of the amacrine cell in a direction opposite to the preferred direction of the ganglion cell connect with the ganglion cell.
