Phys.org / Measuring time at the quantum level depends on material symmetry
EPFL physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the material. "The concept of time has troubled philosophers and physicists for thousands of years, and ...
Phys.org / Aerobic respiration began hundreds of millions of years earlier than previously thought, study suggests
Oxygen is a vital and constant presence on Earth today. But that hasn't always been the case. It wasn't until around 2.3 billion years ago that oxygen became a permanent fixture in the atmosphere, during a pivotal period ...
Phys.org / Broken inversion symmetry lets 3D crystals mimic 2D Ising superconductivity
Two-dimensional (2D) materials, in general, allow the realization of unique quantum phenomena unattainable in the common three-dimensional (3D) world. A prime example is graphene. Transition metal dichalcogenides (TMDs) have ...
Phys.org / Artificial light is reshaping caracal behavior, limiting where the South African wild cat can hunt
Artificial light is one of the most ingrained features of modern life. For humans, light after dark offers convenience and a sense of safety. For wildlife, it's a growing environmental disturbance. "When humans introduce ...
Phys.org / Simulation finds Grass2Gas biogas systems may reduce dairy emissions by over 20%
Implementing novel management practices in dairy farming, one of the commonwealth's major agricultural industries, could help alleviate a large source of both nutrient pollution and greenhouse gas emissions, according to ...
Phys.org / Widening beaches make California 500 acres bigger than it was 40 years ago
Southern California's beaches have grown more than 500 acres over the past four decades despite being one of the most heavily urbanized and dammed coastal regions in the world, according to a new study conducted by researchers ...
Phys.org / Study reveals microscopic origins of surface noise limiting diamond quantum sensors
A new theoretical study led by researchers at the University of Chicago and Argonne National Laboratory has identified the microscopic mechanisms by which diamond surfaces affect the quantum coherence of nitrogen-vacancy ...
Phys.org / New 3D method maps Paleolithic engravings at submillimeter resolution
A team of archaeologists from the Universitat Jaume I, the University of Barcelona, and the Catalan Institution for Research and Advanced Studies (ICREA) has developed a new methodology that allows for a much more detailed, ...
Phys.org / 'Energy efficiency' proves key to how mountain birds adapt to changing environmental conditions
Research led by the University of East Anglia (UEA) sheds new light on how mountain birds adapt to changes in climate. Scientists know that species diversity changes as you go up a mountain, but it is not clearly understood ...
Phys.org / When silicon fills the role of carbon: Debut of all-silicon cyclopentadienides
Carbon's unique chemical properties allow it to be an essential building block for life on Earth and many other molecules we rely on for day-to-day life—but what about carbon's neighbor? Silicon is located one row below ...
Phys.org / Watching a critical green-energy catalyst dissolve, atom by atom
Iridium oxide is one of the most important—and most problematic—materials in the global push toward clean energy. It is currently the most reliable catalyst used in the conversion of energy to chemicals by electrolysis, ...
Phys.org / The internet names a new deep-sea species of chiton
The Senckenberg Ocean Species Alliance (SOSA), in partnership with the scientific publisher Pensoft Publishers and science YouTuber Ze Frank, have let the internet name a newly discovered deep‑sea chiton (a type of marine ...
