Society's increasing technology use and data consumption is causing an information bottleneck, congesting airwave frequencies and sending engineers searching for access to higher capacity bandwidths. Until now, no technology has existed to tap into and successfully use these frequencies, which span 30 to 100 GHz.
A recurring problem in organic electronics technology has been the difficulty in establishing good electrical contact between the active organic layer and metal electrodes. Organic molecules are frequently used for this purpose, but, until recent research at the Helmholtz Center in Germany unraveled this mystery, it was practically impossible to accurately predict which molecules performed well on the job.
A team of researchers in Canada has proposed a new computational model that may become the architecture for a scalable quantum computer. They say the model should use multi-particle quantum walks for universal computation. In a multi-particle quantum walk, particles live on the vertices of a graph and can move between vertices joined by an edge. Furthermore, nearby particles can interact with each other.
Recently, a Los Alamos National Laboratory quantum cryptography (QC) team successfully completed the first-ever demonstration of securing control data for electric grids using quantum cryptography. The project, says experts, shows that quantum cryptography is compatible with electric-grid control communications, providing strong security assurances rooted in the laws of physics, without introducing excessive delays in data delivery.

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? Physicists in New York and Germany have worked together to make this type of nanoscale MRI possible. To do this, researchers used the tiny imperfections in diamond crystals known as nitrogen-vacancy centers.
Physicists in Finland have successfully connected a superconducting quantum bit, or qubit, with a micrometer-sized drum head. With this invention they have transferred information from the qubit to the resonator and back again. This work represents the first step towards creating exotic mechanical quantum states which can preserve the qubit’s information (as a vibration) for a longer period of time.
Microscope manufacturer FEI Company this week announced that Maria Carbajo from the Universidad de Extemadura, Spain, is the winner of the FEI Image Contest for her “Spider Skin” image. The image was obtained using an FEI Quanta DualBeam scanning electron microscope.
Side effects are a major reason that drugs are taken off the market and a major reason why patients stop taking their medications, but scientists are now reporting the development of a new way to predict those adverse reactions ahead of time. The computer-based approach could save patients from severe side effects and save drug companies time and money.
Sandia National Laboratories has issued three information technology (IT) contracts totaling $353 million over a potential term of seven years. The awards streamline IT contracting at the laboratories.
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.
Wireless communications and optical computing could soon get a significant boost in speed, thanks to “slow light” and specialized metamaterials through which it travels. Researchers have made the first demonstration of rapidly switching on and off “slow light” in specially designed materials at room temperature. This work opens the possibility to design novel, chip-scale, ultrafast devices for applications in terahertz wireless communications and all-optical computing.
Engineers at the Korea Advanced Institute of Science and Technology (KAIST) and the Korea Railroad Research Institute have designed a wireless technology that can be applied to high capacity transportation systems such as railways, harbor freight, and airport transportation, and logistics. The technology supplies 60 kHz and 180 kW of power remotely to transport vehicles at a stable, constant rate.
While infrared (IR) microscopy has been used since the 1950s to determine the chemical composition of materials, the spatial resolution of the technique has been limited to tens of micrometers. Researchers at NIST and the University of Maryland have overcome this limitation, demonstrating that a new spectroscopy technique can simultaneously measure a material's topography and chemical composition with nanometer-scale spatial resolution.
There are various boxes today that bring Internet content to TV sets, with popular ones made by Roku and Apple. But Intel Corp. wants to go further and make its box and streaming service a replacement for cable. The company said Tuesday that it will sell a set-top box that brings Internet-delivered movies and shows to a TV set this year, along with a “vastly superior experience” to today’s cable boxes.
The size of electronic components is reaching a physical limit. While 3D assembly can reduce bulk, the challenge is in manufacturing these complex electrical connections. Biologists and physicists in France have recently developed a system of self-assembled connections using actin filaments for 3D microelectronic structures. Once the actin filaments become conductors, they join the various components of a system together.
Ancient languages hold a treasure trove of information about the culture, politics and commerce of millennia past. Yet, reconstructing them to reveal clues into human history can require decades of painstaking work. Now, scientists at the University of California, Berkeley, have created an automated “time machine,” of sorts, that will greatly accelerate and improve the process of reconstructing hundreds of ancestral languages.
A Lawrence Livermore National Laboratory team is working to improve lithium-ion battery performance, lifetime, and safety. Working with Lawrence Berkeley National Laboratory, the scientists are developing a new methodology for performing first-principles quantum molecular dynamics simulations at an unprecedented scale to understand key aspects of the chemistry and dynamics in lithium-ion batteries, particularly at interfaces.
Volcanoes are well known for cooling the climate. But just how much and when has been a bone of contention among historians, glaciologists, and archeologists. Now a team of atmosphere chemists, from the Tokyo Institute of Technology and the University of Copenhagen, has come up with a way to say for sure which historic episodes of global cooling were caused by volcanic eruptions.
Researchers have recently demonstrated magnetic resonance imaging (MRI) on the molecular scale through the use of artificial atoms, diamond nanoparticles doped with nitrogen impurity. Conventional MRI responds to the magnetic fields of atomic nuclei, but this new method improves resolution nearly one million times, allowing scientists to probe very weak magnetic fields such as those generated in some biological molecules and even proteins.
Researchers in Austria have succeeded in constructing a novel matter wave interferometer which enables new quantum studies with a broad class of particles, including atoms, molecules, and nanoparticles. hese lumps of matter are exposed to three pulsed laser light gratings which are invisible to the human eye, exist only for a billionth of a second and never simultaneously.
Using nuclear magnetic resonance spectroscopy and low temperatures, researchers have now succeeded for the first time in "filming" the complex process of protein folding. The process, visualized at atomic resolution, reveals how a protein progressively "loses its shape." The findings may help to gain deeper insights into how proteins assume their spatial structure and why intermediate forms of certain proteins misfold in the event of illness.
Researchers in Europe have recently developed an analysis method that allows objects to be imaged using X-rays or visible light with high accuracy despite fluctuations in wavelength or vibrations. Their method is based on a technique called ptychography, which was invented in the 1960s for microscopy using electrons and has further been developed during recent years to be a reliable high-resolution microscopy technique applicable with X-rays and visible light.
