A tool developed by Keele University researchers has been shown to help detect fake news with an impressive 99% level of accuracy, offering a vital resource in combating online misinformation

The researchers Dr. Uchenna Ani, Dr. Sangeeta Sangeeta, and Dr. Patricia Asowo-Ayobode from Keele’s School of Computer Science and Mathematics, used a number of different machine learning techniques to develop their model, which can scan news content to give a judgment of whether a news source is trustworthy and genuine or not.

The method developed by the researchers uses an “ensemble voting” technique, which combines the predictions of multiple different machine learning models to give an overall score.

Impressively, this technique was accurate in identi...

Quantum Experiment generates Long-range Entanglement in 54-Qubit System

Leveraging Born's rule to realize the Nishimori critical state for constant-depth quantum circuits

The operation and performance of quantum computers relies on the ability to realize and control entanglement between multiple qubits. Yet entanglement between many qubits is inherently susceptible to noise and imperfections in quantum gates.

In recent years, quantum physicists and engineers worldwide have thus been trying to develop more robust protocols to realize and control entanglement. To be most effective for real-world applications, these approaches should reliably support long-range entanglement, or in other words ensure that qubits remain entangled even when they are separated by large distances.

Researchers at IBM Quantum, University of Cologne and Harvard University set out to demonstrate one of these protocols in an experimental setting.

Their paper, published in ...

Test of ‘Poisoned Dataset’ shows Vulnerability of LLMs to Medical Misinformation

By conducting tests under an experimental scenario, a team of medical researchers and AI specialists at NYU Langone Health has demonstrated how easy it is to taint the data pool used to train LLMs.

For their study published in the journal Nature Medicine, the group generated thousands of articles containing misinformation and inserted them into an AI training dataset and conducted general LLM queries to see how often the misinformation appeared.

Prior research and anecdotal evidence have shown that the answers given by LLMs such as ChatGPT are not always correct and, in fact, are sometimes wildly off-base...

We often take for granted just how ubiquitous Wi-Fi has become over the past two decades, explains Northeastern University electrical and computer engineering professor Francesco Restuccia, who is also a member of the Institute for the Wireless Internet of Things.

Wi-Fi provides wireless connectivity to more than 20 billion devices around the globe, including smartphones, laptops, game consoles, and smart TVs. And for most people, Wi-Fi works so smoothly it almost feels magical.

“It’s one of the most pervasive technologies ever invented by mankind,” Restuccia says. “We seamlessly utilize Wi-Fi every day without even knowing we are...
