Phys.org / Quantum-gravitational mechanism could explain the universe's homogeneity

Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.

Phys.org / What one of Emperor Hadrian's latrines is telling us about the durability of Roman concrete

One of the many marvels of the Roman world is that some of its buildings are still with us. But why have they lasted for so long when some relatively modern structures are in a state of decay after a few decades?

Phys.org / Study reports the first detection of a sugar in interstellar space

Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential for the synthesis ...

Phys.org / Firefly brightness holds a cautionary tale about accepting older measurements

For over a century, the accepted value for a firefly's brightness has mostly stood, tracing its origins to experiments carried out in 1912. Through rigorous new analysis published in the American Journal of Physics, David ...

Phys.org / Scientists strike invisible gold in the deep sea—locked inside fool's gold

Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers ...
