Phys.org / New Monte Carlo method accelerates simulations of densely entangled polymer melts

Long polymer chains are everywhere: in synthetic materials, soft matter, biological systems such as chromosomes, and mathematical models of filaments and knots. When many such chains are densely packed, they form what physicists ...

Phys.org / Hidden chemical pathway could keep phosphorus from fueling lake algal blooms

Why do some lakes remain plagued by harmful algal blooms even after phosphorus pollution has been reduced? Part of the answer lies beneath the surface. A new Concordia study has uncovered a previously overlooked chemical ...

Phys.org / Realistic solid-state model brings fractons in quantum spin liquids closer to detection

Quasiparticles arise from the complex interaction of many particles in solids; for example, we describe lattice vibrations in crystals as phonons. Fractons are exotic quasiparticles that occur at the vertices of magnetic ...

Phys.org / First 15 days of egg development may determine survival for California's most endangered salmon

Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat ...

Phys.org / Ocean plankton reveal sugar-for-nutrients partnership that sustains life in barren seas

In the vast, nutrient-poor regions of the world's oceans, there is a constant struggle for survival. Yet tiny organisms known as Collodaria have thrived there for millions of years. These Collodaria host microscopically small ...

Phys.org / Lab-grown brain models gain a sense of place

The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, ...

Phys.org / Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields

An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...

Phys.org / 'Rainbow-on-a-chip' could help unlock 6G networks and precision timing for quantum technologies

Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into ...

Phys.org / Twenty years and 7,500 fossils reveal what blurs Earth's marine fossil record

In productive marine environments, a square meter (10.8 square feet) of seafloor can be perforated by hundreds to thousands of isolated and interconnected tunnels through which crawl and writhe a cornucopia of clams, shrimp, ...

Phys.org / Patience predicts longer education paths and faster earnings growth, real-money experiment finds

Some teenagers are happy to wait for a bigger reward tomorrow rather than cash in today. Others would rather take the sure thing now—or gamble on a risky, high-payoff bet. According to a new study, these everyday differences ...

Phys.org / Stellar spin may explain why repeated black hole flares grow dimmer

At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
