    Ultrafast light wave electronics: Light from inside the tunnel

    Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material processing. Physicists from the Max Born Institute in Berlin and the University of Rostock have now revealed a so-far overlooked nonlinear optical mechanism that emerges […] More

    Countries group into clusters as COVID-19 outbreak spreads

    Mathematicians based in Australia and China have developed a method to analyze the large amount of data accumulated during the COVID-19 pandemic. The technique, described in the journal Chaos, by AIP Publishing, can identify anomalous countries — those that are more successful than expected at responding to the pandemic and those that are particularly unsuccessful.

    World's widest graphene nanoribbon promises the next generation of miniaturized electronics

    Standard semiconductor technology is reaching its limit in miniaturization, but the demand for smaller electrical devices with higher performance continues to grow. The research group introduced the widest graphene nanoribbon prepared by the bottom-up approach with electrical properties surpassing those of silicon semiconductors, promising a new generation of miniaturized electronic devices. With literally the thickness […] More

    Could your computer please be more polite? Thank you

    In a tense time when a pandemic rages, politicians wrangle for votes and protesters demand racial justice, a little politeness and courtesy go a long way. Now researchers at Carnegie Mellon University have developed an automated method for making communications more polite. Specifically, the method takes nonpolite directives or requests — those that use either […] More

    An ethical eye on AI

    Researchers from the University of Warwick, Imperial College London, EPFL (Lausanne) and Sciteb Ltd have found a mathematical means of helping regulators and business manage and police Artificial Intelligence systems’ biases towards making unethical, and potentially very costly and damaging commercial choices — an ethical eye on AI. Artificial intelligence (AI) is increasingly deployed in […] More

    Understanding of relaxor ferroelectric properties could lead to many advances

    A new fundamental understanding of polymeric relaxor ferroelectric behavior could lead to advances in flexible electronics, actuators and transducers, energy storage, piezoelectric sensors and electrocaloric cooling, according to a team of researchers at Penn State and North Carolina State. Researchers have debated the theory behind the mechanism of relaxor ferroelectrics for more than 50 years, […] More

    Using cellular networks to detect at-risk areas for spread of COVID-19

    In the fight against COVID-19, researchers at Colorado State University have developed a new, non-invasive strategy to identify areas at greatest risk for spreading the disease. Led by Electrical and Computer Engineering Professor Edwin Chong, the team is drawing on data from existing cellular wireless networks to pinpoint potential hotspots for increased viral transmission. Their […] More

    Even when women outnumber men, gender bias persists among science undergrads

    Increasing gender diversity has been a long-sought goal across many of the sciences, and interventions and programs to attract more women into fields like physics and math often happen at the undergraduate level. But is representation enough to improve gender diversity in science? In a new study, Colorado State University researchers say there’s more to […] More
