Phys.org / Study suggests three-quarters of Indo-Pacific coral reefs could drown as sea levels rise

Nanyang Technological University, Singapore (NTU Singapore) scientists have found that most coral reefs across the Indo-Pacific may struggle to grow fast enough to keep pace with accelerating sea-level rise. Their study found ...

Phys.org / New photonic crystal method improves single-photon sources for quantum networks

Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission of large amounts of data. However, it requires single photons—and generating them is very difficult. ...

Phys.org / 'Hidden stars' suggest that distant galaxies are much more massive than they appear

Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. ...

Phys.org / Rare satellite data reveal major limits in flood models

The Kakhovka Dam in southern Ukraine was destroyed on June 6, 2023. The event unleashed a catastrophic flood that forced thousands of residents to evacuate their communities as water levels rose 10 feet (3 meters) above normal.

Phys.org / A single asteroid impact may explain the appearance of Mars' moon Deimos

Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...

Phys.org / Unusual superconductivity could emerge in valley-imbalanced rhombohedral graphene

Superconductors are materials in which electrical current flows with a resistance of zero, typically below specific temperatures. In conventional superconductors, this state of matter emerges when two electrons bind together ...

Phys.org / Existing drug could treat invasive canine oral tumors

A benign but invasive canine oral cancer is often mistaken for a similar malignant one, leading to misdiagnoses in close to a third of cases. But a new diagnostic tool can now distinguish between the two, according to a new ...

Phys.org / Ruby-forming mineral found by Mars rover hints at violent impacts

So far, most of the minerals found on Mars tell a story of lava poured out by ancient volcanoes, followed by long stretches in which water trickled through and slowly reshaped the rock. However, some rocks scattered across ...

Phys.org / A new approach to building noise-resistant quantum sensors

Quantum sensors, devices that collect measurements by exploiting quantum-mechanical phenomena, could potentially detect extremely weak magnetic, gravitational and electromagnetic signals with greater sensitivity than classical ...

Phys.org / Scientists 'see' nanoscale forces, providing evidence of electric fields at the air‑water interface

Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?

Phys.org / Curved surfaces reshape active materials, localizing vibrations near defects

Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such 'active' materials operate, but so far, mostly in circumstances where the curvature of the environment ...

Phys.org / Secrets of a mystery mammal from Patagonia revealed at last

Eight years of painstaking research on the virtually unknown Wolffsohn's viscacha have helped to shine the spotlight on this super-rare South American rodent and catalyze the conservation action it so urgently needs.
