Boosting Superconductivity in Graphene Bilayers
Nearly a decade ago, researchers heralded the discovery of a new wonder class of ultrathin materials with special optical and electrical properties that made it a potential rival for graphene, a form of carbon discovered in 2004 whose own special properties interest both scientists and engineers. Now, Caltech engineers have shown that one of these wonder materials, tungsten diselenide, is not just a rival to graphene but also a complement to it.

A GPS for Smart Pills
The idea of journeying inside the human body to solve medical problems has been around at least since a hokey sci-fi film popularized the concept in the 1960s, but this approach to medicine has never become real because shrinking rays, sadly, do not exist. However, researchers have developed proxies for human doctors that are small enough travel through the human body and help diagnose ailments.

Ingestible sensor could help doctors pinpoint GI difficulties
The sensor sends out its location as it moves through the GI tract, revealing where slowdowns in digestion may occur. Close Engineers at MIT and Caltech have demonstrated an ingestible sensor whose location can be monitored as it moves through the digestive tract, an advance that could help doctors more easily diagnose gastrointestinal motility disorders such as constipation, gastroesophageal reflux disease, and gastroparesis.

Scientists boost quantum signals while reducing noise
"Squeezing" noise over a broad frequency bandwidth in a quantum system could lead to faster and more accurate quantum measurements. Close A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer , which harnesses quantum mechanical phenomena to solve certain problems too complex for classical computers, the same quantum mechanics also imparts a minimum level of unavoidable error that limits the accuracy of the measurements.

Superconductivity switches on and off in ’magic-angle’ graphene
A quick electric pulse completely flips the material's electronic properties, opening a route to ultrafast, brain-inspired, superconducting electronics. Close With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in "magic-angle" graphene: superconductivity that can be turned on and off with an electric pulse, much like a light switch.

Long-range information transport in antiferromagnets
Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

Researchers at ETH have developed a technique to cool several nanoparticles simultaneously to temperatures of just a few thousandths of a degree above absolute zero. This new method can be used to study quantum effects of several nanoparticles and to build highly sensitive sensors. Over the past forty years, physicists have learned to cool increasingly large objects down to temperatures close to the absolute zero: atoms, molecules and, more recently, also nanoparticles consisting of billions of atoms.
