In recent years, topological insulators have become one of the hottest topics in physics. These new materials act as both insulators and conductors, with their interior preventing the flow of electrical currents while their edges or surfaces allow the movement of a charge. Perhaps most importantly, the surfaces of topological insulators enable the transport of spin-polarized electrons while preventing the
Scientists have made the world’s first junctionless transistor even smaller. The transistor is the building block of the microchip.
Scientists have developed a simple and fast process to manufacture high-quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate, enabling them to manufacture the world
Engineers and scientists collaborating at Harvard University and the MITRE Corporation have developed and demonstrated the world
By imaging fluorescence from gold within a bowtie-shaped device and maximizing the number of photons collected from the device, a Berkeley Lab team has been
Physicists from the University of Birmingham, with colleagues at Imperial College, London and Technical University of Denmark, have demonstrated an
In a complex feat of nanoengineering, a team of scientists at Kyoto University and the University of Oxford have succeeded in creating a programable molecular transport system, the workings of which can be observed in real time. The results, appearing in the latest issue of Nature Nanotechnology, open the door to the development of advanced drug delivery methods and molecular manufacturing systems.
Since the days of Darwin, the
Researchers have discovered a new way of splitting layered materials to give atom-thin nanosheets.This has led to a range of novel two-dimensional
An ambitious hunt by Johns Hopkins scientists for actively "jumping genes" in humans has yielded compelling new evidence that the genome, anything but static, contains numerous pesky mobile elements that may help to explain why people have such a variety of physical traits and disease risks.
Are we on the verge of being able to stimulate the brain to see the world anew -- an electric thinking cap? Researchers suggests that this could be the case.
Researchers at the University of Rochester have now identified a genetic switch that controls oxidative stress in stem cells and thus governs stem cell function.
In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery, described in the Feb. 3 issue of Science Express, can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams.
Scientists have identified the genetic sequence of an unprecedented 28,000 structural variants -- large portions of the human genome which differ from one person to another. The work could help find the genetic causes of some diseases and also begins to explain why certain parts of the human genome change more than others.
