Phys.org / Mathematical 'sum of zeros' trick exposes topological magnetization in quantum materials
A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to non-equilibrium regimes. It demonstrates that a superficially trivial "sum of zeros" encodes a universal, ...

Phys.org / Researchers revive the pinhole camera for next-gen infrared imaging
Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a large range of distances ...

Phys.org / Newly dated 85-million-year-old dinosaur eggs could improve understanding of Cretaceous climate
In the Cretaceous period, Earth was plagued by widespread volcanic activity, oceanic oxygen depletion events, and mass extinctions. Fossils from that era remain and continue to give scientists clues as to what the climate ...

Phys.org / Circuits invisible to the naked eye: New technique shrinks microchips beyond current size limits
Johns Hopkins researchers have discovered new materials and a new process that could advance the ever-escalating quest to make smaller, faster and affordable microchips used across modern electronics—in everything from ...

Phys.org / Metals reveal trade in Bronze Age more connected than previously thought
In the Bronze Age, the so-called Nuraghe culture flourished in Sardinia. A culture that is known for tower-like stone constructions, nuraghers, and for the small bronze figures, bronzetti, which often depict warriors, gods ...

Phys.org / A new view of the proton and its excited states
The small but ubiquitous proton serves as a foundation for the bulk of the visible matter in the universe. It abides at the very heart of matter, giving rise to everything we see around us as it anchors the nuclei of atoms. ...

Phys.org / How interstellar objects similar to 3I/ATLAS could jumpstart planet formation around infant stars
Interstellar objects like 3I/ATLAS that have been captured in planet-forming disks around young stars could become the seeds of giant planets, bypassing a hurdle that theoretical models have previously been unable to explain.

Phys.org / Key diagnostic system for experimental fusion reactor nears completion
In the universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth, producing energy using this process is difficult due to problems with controlling the plasma emitting significant ...

Phys.org / Turbulence with a twist: New work shows fluid in a curved pipe can undergo discontinuous transition
Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent ...

Phys.org / New dinosaur from Wales identified in museum drawer
Paleontologists at the University of Bristol have officially identified a new species of dinosaur from Triassic fossil beds in South Wales, near Penarth—more than 125 years after the specimen was initially reported.

Phys.org / Clocks created from random events can probe 'quantumness' of universe
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King's College London reveal. The paper is published in the journal Physical Review X.

Phys.org / Newly developed organic compounds can serve as highly sensitive oxygen sensors
Researchers at Kaunas University of Technology (KTU), Lithuania, have developed new organic compounds that act as highly sensitive oxygen sensors. These sensors can accurately detect even the slightest amounts of oxygen in ...
