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 / Hidden fifth dimension could tune dark matter resonance, new theory proposes
The mysterious substance that binds galaxies together could naturally be "in tune" with a hidden fifth dimension, according to a new University of Sheffield theory aiming to shed light on one of science's biggest enigmas: ...
Phys.org / New 3D thermal cloak hides objects from heat in any direction
Researchers have designed and built the first 3D device that can make objects invisible to heat, an advance that could transform how we protect sensitive electronics, manage heat in microchips and shield equipment from thermal ...
Phys.org / The US just approved a giant space mirror to test 'sunlight on demand.' Low Earth orbit is getting weird
A giant mirror to create "sunlight on demand" was just approved by the United States Federal Communications Commission (FCC), despite opposition from astronomers and the public, and real safety concerns.
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 / Six massive landslides discovered on icy Pluto
Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in ...
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 ...
Phys.org / World's first superconducting quantum heat engine offers path to larger quantum computers
Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a boost to quantum technology, and a clearer picture of quantum thermodynamics could in turn enhance our ...
Phys.org / Study links sea level to Earth's carbon thermostat
Earth has a natural thermostat that has kept the planet habitable for more than 100 million years. Scientists have struggled to fully explain how it works, but new research identifies a missing link between phosphate availability ...
Phys.org / As super El Niño draws global attention, the Indian Ocean may hold the key to Mediterranean climate extremes
As scientists around the world closely monitor the possible development of a powerful "Super El Niño," a new study suggests that another tropical ocean deserves equal attention. Researchers have found that temperature changes ...
