Phys.org / Review finds lack of evidence as to whether planting around our homes reduces the pollution we breathe

A new review led by the University of East London (UEL) has uncovered a major blind spot in air pollution research. Despite domestic gardens covering vast areas of Britain's towns and cities, researchers found no direct evidence ...

Phys.org / Astronomers are still trying to understand how a galaxy's spiral arms form

The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since astronomers didn't know ...

Phys.org / A quantum heat engine that simultaneously provides work and refrigeration

The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...

Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds

When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...

Dialog / Near a black hole, gravity changes a quantum circuit's readings, not its rules

Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...

Phys.org / Gamma-ray pulsations reveal extreme 3.2-millisecond pulsar 3,900 light-years away

By analyzing the data from NASA's Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray ...

Phys.org / Angola's oldest burials, including its only known ancient cremation, uncovered at a 15th-century site doomed by a dam

As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.

Phys.org / Microscale roughness breakthrough defies 80 years of fluid dynamics

Logically, you would think a sleek surface has optimal aerodynamics—but recent research at Tohoku University turns this fundamental principle on its head. Applying an irregular microscale surface texture reduced the aerodynamic ...
