This is an important breakthrough because high-frequency bands are prone to logjams because of high demand. On the other hand, microwave photonics offers high bandwidth, low transmission loss, and immunity to electromagnetic interference.
The first coronavirus digital contact-tracing app using OS updates from Google and Apple is now in a large-scale pilot test. Dubbed as SwissCovid, the app is based on the decentralized protocol, where operations that have data privacy implications are not stored or conducted through a centralized server, but on the phone of individual users. Employees at EPFL, ETH Zurich, the Swiss Army, and select hospitals and cantonal administrations can now download the app for tracing contacts at risk of transmission of COVID-19.
Mathias Payer and Hui Peng have developed a USB software security tool called USBFuzz. The researchers plan to release USBFuzz on GitHub as an open source project following their presentation at Usenix.

Computer Science is taking rapid strides in realigning itself to advancing technologies. It is beginning to emerge from the cocoon of traditional research to address new challenges posed by avant-garde technologies. In an article published in EPFL Magazine in December 2019, School of Computer and Communication Sciences (IC) Dean James Larus recorded his candid observations on the current status of the discipline at EPFL and the way forward.
Most discourses on the risks of Artificial Intelligence tend to focus on tech applications that are in the future horizon. The preoccupation with perceived threats such as sentient robots and AI consciousness takes away attention from AI-related issues that are already in the present, affecting simple daily activities such as reading the news, watching YouTube, or using a smartphone app. As School of Computer and Communication Sciences (IC) researchers Lê Nguyên Hoang and El Mahdi El Mhamdi emphasize in their new book, there is an urgent need to restate ethical questions related to algorithms in computational terms.
Seaside in Monterey County, California, will host the 28th ACM/SIGDA International Symposium on Field-Programmable Gate Arrays (FPGA) between February 23 and 25 this year.

Today, we have a slew of media houses and streaming services that inundate consumers with audio, video, online, and print news. This has raised the specter of rampant news misinformation and disinformation. The threat is amplified by broadcasters who use the same source to disseminate news to consumers. Any bias in the original news source is perpetrated by all secondary services, thus delivering a limited view of news to consumers. However, researchers at EPFL’s Distributed Information Systems Laboratory (LSIR) in the School of Computer and Communication Sciences have developed an algorithm that can detect such biases and external influences in the news industry.
