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 ...

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 ...

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 ...

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 ...

Electron movement and structures described in quantum physics allow researchers to better understand how and why materials like superconductors behave as they do. Rice University researchers Jianwei Huang and Ming Yi have ...

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. ...

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 ...

Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have created a chip-scale device that can dynamically control the "handedness" of light as it passes through—also known as its ...

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.

New genetic testing from the University of the Sunshine Coast has uncovered the extraordinary lengths a group of Queensland seabirds will travel to keep love blossoming on their little island. It's a common complaint for ...

Drug delivery researchers have vastly improved the potential of genetic therapies by overcoming the challenge of consistently getting genes and gene-editing tools where they need to be within cells. Findings of the study ...

By 2050, up to half the world's urban population will face water scarcity. A new model of water supply, demand, and policies in a drought-prone city of 7 million in India shows how policies could prevent the poor from bearing ...
