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

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

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

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

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

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

A picture is worth a thousand words -but only when it’s clear what it depicts. And therein lies the rub in making images or videos of microscopic life. While modern microscopes can generate huge amounts of image data from living tissues or cells within a few seconds, extracting meaningful biological information from that data can […] More

Researchers at Carnegie Mellon University have developed an efficient new way to quickly analyze complex geometric models by borrowing a computational approach that has made photorealistic animated films possible. Rapid improvements in sensor technology have generated vast amounts of new geometric information, from scans of ancient architectural sites to the internal organs of humans. But […] More
