Phys.org / Hydrogen atmosphere could keep exomoons habitable for billions of years
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck ...
Phys.org / Dolphin mass strandings in Patagonia linked to killer whales
In 2021 and 2023, hundreds of dolphins were stranded in shallow waters in San Antonio Bay in northern Patagonia. Some died, but many were returned safely to the sea. But what remained a mystery until now was how they ended ...
Phys.org / Flash heating upcycles waste glass into SiC nanowires in seconds
Engineering silicon carbide (SiC) with tailored morphologies for electronics and structural reinforcement materials has always been a costly and time-consuming affair, but scientists can now do it in a flash. A new study ...
Phys.org / Astronomers collect rare evidence of two planets colliding
Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from Earth near the constellation ...
Phys.org / Centuries of net-negative emissions are required to secure a safe climate future, two studies suggest
Two new studies conclude that stabilizing long-term climate risks will require sustained net-negative carbon dioxide (CO₂) emissions for centuries. Approaching the problem from distinct perspectives—legal and technological ...
Phys.org / Stacked quantum materials enable precise spin control without external magnetic fields
Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge has been the ability ...
Phys.org / Compact vacuum ultraviolet laser may improve nanotechnology and power nuclear clocks
Physicists at the University of Colorado Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The researchers say the device could ...
Phys.org / Galaxy-group motion suggests slower expansion in our cosmic neighborhood
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
Phys.org / Highlighting the hidden climate cost of the Israel–Gaza war
A new study estimates that the Israel–Gaza war has generated around 33 million metric tons of carbon dioxide equivalent (CO2e), highlighting the often-overlooked environmental impact of armed conflict.
Phys.org / Simulations suggest a breakthrough in understanding how turbulence develops
A new study revisits a century-old question about how turbulence starts. The findings could potentially influence not only aircraft engineering but even the design of mechanical heart valves, and treatment of heart disease. ...
Phys.org / DNA origami vaccine rivals mRNA shots while being easier to store and manufacture
The COVID-19 pandemic brought messenger RNA (mRNA) vaccines to the forefront of global health care. After their clinical trial stages, the first COVID-19 mRNA vaccine was administered on 8 December 2020 and mathematical models ...
Phys.org / Photonic 'ski jumps' efficiently beam light into free space
Photonic chips use light to process data instead of electricity, enabling faster communication speeds and greater bandwidth. Most of that light typically stays on the chip, trapped in optical wires, and is difficult to transmit ...
