Phys.org / Bowhead whale recovery reflects century-old whaling patterns
An international study led by Adelaide University has found bowhead whale populations are recovering only in stocks where large areas of hazardous sea ice conditions limited devastating hunting centuries ago. The research ...
Phys.org / This ultracold quantum device turns electricity into something far stranger that could unlock sound-based lasers
Researchers at McGill University have developed a novel device that generates sound-like particles known as phonons at extremely cold temperatures. The technology could be used to create phonon lasers, with possible applications ...
Phys.org / An unprecedented Antarctic heat wave hit in the dead of winter—what it signals for the decades ahead
In the middle of the Antarctic winter, during months of darkness when temperatures often dip below −30°C, the continent warmed dramatically. In July and August 2024, temperatures in parts of East Antarctica rose by up to ...
Phys.org / Simulations predict ground motion for earthquakes on Bay Area's Hayward fault
The Hayward fault, part of the larger San Andreas fault system, runs 74 miles through the East Bay of the San Francisco Bay Area. The fault is overdue for an earthquake that could cause extensive damage to such a dense population ...
Phys.org / Sewers have been hiding a climate problem in plain sight, and this new tool finally exposes its true scale
Methane is the second-largest greenhouse gas after carbon dioxide. According to the Climate and Clean Air Coalition, anthropogenic methane emissions account for nearly 45% of current net warming, making it an important factor ...
Phys.org / Room-temperature vibrations could transform how industry makes graphene
Researchers have demonstrated a new technique for creating 2D materials that runs at room temperature and increases production rates tenfold over current methods, without using toxic solvents. Scientists led by Dr. Jason ...
Phys.org / At just four nanometers thick, this metal starts behaving in a way physicists did not expect
Researchers in the University of Minnesota Twin Cities have discovered a powerful new way to control the electronic behavior of a metal—by manipulating the atomic properties of materials where they meet. The study, published ...
Phys.org / Aligned cells may explain why some wounds heal faster than others
Understanding how wounds heal after injury could be a step closer thanks to a new mathematical model developed by researchers at the University of Bristol. The study, published in Physical Review Letters, builds on previous ...
Phys.org / Breaking connections helps ideas spread farther, says physics-based study
Sticking with the same people might feel safe and comfortable. But a new Northwestern University study suggests it can actually trap new ideas and behaviors inside tight echo chambers. By contrast, the research, published ...
Phys.org / Fragile no more, nickelates get an upgrade that changes how superconductivity endures
Discovered in 2019, the material known as nickelates has intrigued researchers for its potential to become a superconductor at elevated temperatures—a property that could significantly advance such fields as quantum science ...
Phys.org / Rivers worldwide reveal greenhouse gas rise that's been overlooked for decades
Rivers worldwide are under severe stress: they are warming, losing oxygen, and as a result emitting increasing amounts of greenhouse gases. Researchers at Karlsruhe Institute of Technology (KIT) have now quantified these ...
Phys.org / Light-based scans reveal how cells can be stable yet adaptable
Our cells adjust to ever-changing conditions while preserving internal states necessary for survival, but exactly how they achieve both adaptability and stability remains unclear. For the first time, researchers have used ...
