Technology

TVs keep getting more pixels—but we are approaching the limits of what our eyes can actually see

March 23, 2026 Tech Xplore

I remember sitting very close to the television as a child and seeing the image was made up of tiny colored dots, each of which broke down into miniature vertical strips of red, green and […]

Researchers achieve 100-meter underground wireless communication

March 23, 2026 Tech Xplore

Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless communication they have primarily focused on until now. This opened up a new wireless channel for confirming the survival of […]

Technology

Sound waves could be used to remotely reprogram material stiffness, from implants to robotic muscles

March 22, 2026 Tech Xplore

A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans University has demonstrated a […]

Turning extreme heat into large-scale energy storage

March 22, 2026 Tech Xplore

Thermal batteries can efficiently store energy as heat. But building them requires a carefully designed system with materials that can withstand cycles of extremely high temperatures, without succumbing to problems like corrosion, thermal expansion, and […]

Highly performing AI agents can still fail to spot deception, study finds

March 21, 2026 Tech Xplore

Large language models (LLMs), artificial intelligence systems that can process and generate texts in different languages, are now used daily by many people worldwide. As these models can rapidly source information and create convincing content […]

Technology

Magnets turn random snapping in soft metamaterials into repeatable sequences

March 20, 2026 Tech Xplore

Cutting patterns into elastic materials allows you to unfold those materials into new shapes, and researchers have now demonstrated the ability to control the sequence in which that unfolding happens by magnetizing the materials. The […]

Swimming robot propelled by lab-grown muscle hits record speed

March 19, 2026 Tech Xplore

NUS researchers have developed a platform that lets lab-grown muscle tissues train themselves to record-breaking strength, with no external stimulation required. By mechanically coupling two muscle tissues so they continuously pull against each other, their […]

Technology

New X-ray vision for electronics lets scientists monitor working chips remotely

March 19, 2026 Tech Xplore

A team of international researchers have developed a breakthrough way to observe what is happening inside electronic chips while they are operating—without touching them, taking them apart, or switching them off. The new technique uses […]

Computers

A better method for identifying overconfident large language models

March 19, 2026 Tech Xplore

Large language models (LLMs) can generate credible but inaccurate responses, so researchers have developed uncertainty quantification methods to check the reliability of predictions. One popular method involves submitting the same prompt multiple times to see […]

Video streaming speed changes could help replace pauses and the frustrating buffering circle

March 18, 2026 Tech Xplore

Viewers would rather watch video at slightly lower speeds than endure rebuffering, according to new research from Lancaster University. The study investigated how dynamically slowing down or speeding up playback is perceived by viewers, and […]
