Scientists have discovered a way to efficiently transfer electrical current through specific materials at room temperature, a finding that could revolutionize superconductivity and reshape energy preservation and generation.

The paper is published in the journal Physical Review Letters.

The much-sought-after breakthrough hinges on applying high pressure to certain materials, forcing their electrons closer together and unlocking extraordinary electronic behaviors.

“Our research explores how electrons interact inside solid materials—interactions that give rise to remarkable phenomena such as high-temperature superconductivity and charge-density waves (CDWs),” said Dr. Mahmoud Abdel-Hafiez, associate professor of physics at the University of Sharjah.

“These effects are impo...

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair.

Published in the journal Nature Communications, the breakthrough optical phase modulators could help unlock much larger quantum computers by enabling efficient control of lasers required to operate thousands or even millions of qubits—the basic units of quantum information.

Critically, the team of scientists have developed these devices using scalable manufacturing, avoiding complex, custom builds in favor of those used to make the same technology behind processors already found in computers, phones, vehicles, home appliances—virtu...

Reduced coronary blood flow, measured with an artificial intelligence-based imaging tool, predicted future cardiovascular events in patients with suspected stable coronary artery disease. These findings were presented at EACVI 2025, the congress of the European Association of Cardiovascular Imaging (EACVI).

Stable coronary artery disease (CAD) refers to the common syndrome of recurrent, transient episodes of chest symptoms, often manifesting as angina. Coronary computed tomography angiography (CCTA) is a noninvasive heart scan that is used as the first-line investigation for patients with suspected stable CAD.

AI tools and FFR-CT explained
While CCTA clearly shows blockages in coronary arteries, it is limited in its ability to estimate reduced blood flow...

Generative AI and robotics are moving us ever closer to the day when we can ask for an object and have it created within a few minutes. In fact, MIT researchers have developed a speech-to-reality system, an AI-driven workflow that allows them to provide input to a robotic arm and “speak objects into existence,” creating things like furniture in as little as five minutes.

With the speech-to-reality system, a robotic arm mounted on a table is able to receive spoken input from a human, such as “I want a simple stool,” and then construct the objects out of modular components...
