- 1Climate change found to subtly slow Earth's rotation▼When the atmosphere slows the Earth: Uncovering a subtle signal of climate change
Scientists have identified a subtle new signal of climate change: shifting atmospheric dynamics linked to global warming are measurably slowing the Earth's rotation. As warming redistributes mass in the atmosphere and oceans, it alters the planet's angular momentum, lengthening days by tiny fractions of a second. The finding, reported by Phys.org, adds to evidence that human-driven climate change affects even fundamental planetary processes, and researchers say it could matter for precise timekeeping systems.
- 2Cooper pairs found surviving above superconducting critical temperature▼Cooper pairs found above superconducting critical temperature in pair density waves
Physicists report detecting Cooper pairs persisting above the superconducting critical temperature within pair density waves, a phase previously thought to exist only below the threshold where resistance vanishes. The finding, covered by Phys.org, suggests superconducting correlations can survive into a regime where they do not produce zero resistance, sharpening debates over how unconventional superconductors like cuprates behave near their transition point.
- 3Researcher Solves Nanoparticle Mystery Using an iPhone Camera●Researcher Solves a Nanoparticle Mystery Using an iPhone Camera
A researcher has resolved a longstanding puzzle in nanoparticle science using only an iPhone camera, according to reports from StatNano and Phys.org. The work suggests that ordinary smartphone hardware, combined with the right analytical method, can achieve results previously thought to require specialised laboratory equipment. Details of the researcher's identity, institution and the specific mystery solved were not provided.
- 4Platinum surface tweak boosts solar hydrogen production▼Changes to platinum surface chemistry boost solar hydrogen production in organic photocatalysts
Researchers report that modifying the surface chemistry of platinum significantly improves solar hydrogen production in organic photocatalysts. The finding, covered by Phys.org, points to a way to make light-driven water splitting more efficient, a key step toward clean hydrogen fuel. Details of the study, the research team and the size of the efficiency gain have not yet been widely reported.
- 5Nobel Prize Honored First Particle Accelerator Physicists 75 Years Ago●Physicists who uncovered the first particle accelerator were honored with a Nobel Prize 75 years ago
Phys.org is revisiting the moment, 75 years ago, when physicists behind the first particle accelerator received the Nobel Prize, marking a milestone in modern physics. The retrospective recalls how their work opened the way for the high-energy accelerators used in laboratories around the world today, though the article offers no new developments in the field.
