A novel carbon-based biosensor is set to drive new innovations in brain-controlled robotics. The biosensor adheres to the skin of the face and head in order to detect electrical signals being sent by the brain. These signals can be translated into commands to control autonomous robotic systems. The sensor, made of epitaxial graphene grown onto a silicon carbide on silicon substrate, overcomes three major challenges of graphene-based biosensing: corrosion, durability and skin-contact resistance.

Some of the same brain systems known to play a role in learning from trial and error also are engaged when people conform to social norms, scientists report in a new study.

Author(s): Sebastian Meier, Paulo E. Faria Junior, Ferdinand Haas, Emma-Sophia Heller, Florian Dirnberger, Viola Zeller, Tobias Korn, Jaroslav Fabian, Dominique Bougeard, and Christian SchüllerThe observation of electronic Raman scattering in one-dimensional semiconductors has so far been limited to arrays of laterally structured quantum wells. Recent progress in the growth of core-shell nanowires has opened the possibility to reach the quantum confinement regime for single nanowires. Here, the authors present measurements of the one-dimensional subband structure of single wurtzite-phase GaAs nanowires by resonant Raman spectroscopy. The obtained energetic distances between consecutive electron or hole subbands are nicely reproduced by realistic k∙p band structure calculations. [Phys. Rev.

These materials may also be the key to quantum computers that are less susceptible to interference.

Technologies that take advantage of novel quantum mechanical behaviors are likely to become commonplace in the near future. These may include devices that use quantum information as input and output data, which require careful verification due to inherent uncertainties. The verification is more challenging if the device is time dependent when the output depends on past inputs. For the first time, researchers using machine learning dramatically improved the efficiency of verification for time-dependent quantum devices by incorporating a certain memory effect present in these systems.

The adoption of high-dimensional quantum states in quantum information protocols enables better performances in applications ranging from secure quantum communications to fault-tolerant quantum computation. Development of universal protocols able to engineer arbitrary high-dimensional quantum states would be a significant achievement. Several strategies and platforms have been proposed and developed to this end. Quantum-walk (QW) dynamics have been shown to allow development of universal, platform-independent state engineering protocols. However, the unavoidable presence of noise, and imperfections in the characterization of experimental apparatuses, diminish the overall quality of the state generation.

Linus Pauling and Robert Corey described the rippled beta sheet in 1953, two years after introducing the concept of the pleated beta sheet.
