Malicious COVID-19 online content -- including racist content, disinformation and misinformation -- thrives and spreads online by bypassing the moderation efforts of individual social media platforms, according to a new study by researchers at the George Washington University.
Social media and other forms of communication technology restructure these interactions in ways that have consequences. Unfortunately, we have little insight into whether these changes will bring about a healthy, sustainable and equitable world. As a result, researchers now say that the study of collective behavior must rise to a "crisis discipline," just like medicine, conservation and climate science have done, according to a new paper published June 14 in the Proceedings of the National Academy of Sciences.
Scientists at Tokyo Institute of Technology and NEC Corporation jointly develop a 28-GHz phased-array transceiver that supports efficient and reliable 5G communications. The proposed transceiver outperforms previous designs in various regards by adapting fast beam switching and leakage cancellation mechanism.
Events of the past year have exposed the crisis of the nation's digital divide. To tackle this problem, Michigan State University researchers have developed a new tool to smooth the collection of federal broadband access data that helps pinpoint coverage gaps across the US.
Researchers have long believed that as we move up into 6G frequency, the ways in which a signal can reach a receiver will be greatly limited. New research shows that this is not always accurate..Making 6G technology a reality is an important step towards realizing a whole host of new applications including haptic internet, mobile edge computing, and holographic communications. All three of these areas have the potential to change the face of communications, health, transportation, education, and more.
Researchers found differences in sociodemographic and clinical characteristics by entry location for SARS-CoV-2 testing within a safety-net health system. White and English-speaking individuals disproportionately initiated testing via telehealth visits, while black, Native American and non-English-speaking patients disproportionately initiated testing through the emergency department.
When shopping online, participants surveyed spent more money, purchased more items, and spent less on candy and desserts than when they shopped in-store, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.
New dual band stabilisation technique cancels the problem of temperature fluctuations to allow long distance quantum communication. Quantum key distribution demonstrated on fibres of record 600km length. Significant advance towards building a global quantum internet.
What The Study Did: Researchers analyzed conversations on public Facebook groups to explore automated misinformation.
The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place between four parties simultaneously.
