Scientists Discover Quantum Effect That Could Power Devices Without Batteries
Researchers have found that microscopic imperfections and atomic vibrations in an advanced material can be harnessed to convert ambient alternating electrical signals directly into usable direct current. This quantum effect, which can be tuned by changing temperature, bypasses the need for traditional electronic components. The discovery could eventually lead to self-powered devices that harvest energy from their environment, potentially eliminating the need for conventional batteries.
Scientists have identified a quantum mechanism in an advanced material that allows microscopic imperfections and atomic vibrations to control the conversion of alternating electrical signals into direct current — the type of electricity that electronic devices require to operate. Unlike conventional rectification, which relies on standard electronic components, this process operates at the quantum level and does not require traditional hardware. A particularly notable feature of the effect is its temperature sensitivity: as temperature changes, the direction of the converted current can reverse, giving researchers a precise way to tune device performance. This tunability could make the technology adaptable for a wide range of applications. If developed further, the discovery could underpin a new generation of self-powered electronics that harvest ambient electromagnetic energy from their surroundings, reducing or eliminating dependence on batteries.
What's missing
The article does not specify what the 'advanced material' is, what stage of development the research is at, or whether the effect has been demonstrated in a practical device rather than a laboratory setting. Details about the research institution, journal publication, and timeline to real-world application are also absent.
How coverage differed
Only one source was provided for this story, Science Daily, which is rated as center-leaning. The framing is straightforwardly scientific with a forward-looking headline that emphasizes potential applications. Without additional sources, it is not possible to assess cross-outlet framing differences.

Widespread US Heat Wave Brings Dangerous Temperatures Across Multiple Regions
A significant heat wave is spreading across the central United States with heat index values forecast to exceed 110 degrees in parts of Texas and 100 degrees across multiple states including Missouri, Kansas, Iowa, Arkansas, and Tennessee. The National Weather Service warns that early-season heat waves pose greater risks for heat-related illness and could break daily temperature records across numerous states. The extreme heat is expected to impact more than 20 cities, with temperatures 10-20 degrees above normal in some regions, particularly the Upper Midwest and Great Lakes area.
Study Finds Noncognitive Skills Like Motivation and Curiosity Critical to Academic Success
Researchers at Queen Mary University of London conducted a major study showing that noncognitive skills such as motivation, curiosity, academic interest, and self-belief significantly influence how children translate their genetic potential into actual academic achievement. The research highlights that beyond innate ability, psychological and behavioral factors are essential determinants of educational outcomes. This finding suggests that interventions targeting motivation and attitude may be as important as traditional academic support in improving student performance.
NASA Announces Four-Person Crew for Artemis III Moon Mission
NASA has announced the crew for Artemis III, consisting of NASA astronauts Andre Douglas, Randy Bresnik, and Frank Rubio, along with ESA astronaut Luca Parmitano. The mission will test integrated operations between NASA's Orion spacecraft and commercial lunar landers from SpaceX and Blue Origin. This represents a significant step in NASA's plan to return humans to the Moon and establish sustainable lunar exploration capabilities.
