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 / Researchers use AI to develop RNA-based synthetic NAND switch in living cells
An interdisciplinary research team from two working groups at the Center for Synthetic Biology at TU Darmstadt has developed the first RNA-based genetic switch that precisely replicates the logical behavior of a NAND gate, ...
Phys.org / Howler monkey ancestors began eating leaves 13 million years ago, changing course of primate history in South America
Thirteen million years ago, a group of medium-sized monkeys known for guarding their territory among the treetops with fearsome "howls" started doing something new. These monkeys, among the oldest known ancestors of the modern ...
Phys.org / Twisted bilayer photonic crystals dynamically tune light's handedness
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 ...
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 ...
Phys.org / Fiber setup compresses mid-infrared pulses to 187 femtoseconds using just 80 watts
Ultrashort mid-infrared (mid-IR) laser pulses are essential for applications such as molecular spectroscopy, nonlinear microscopy, and biomedical imaging, but their generation often relies on complex and power-intensive systems ...
Phys.org / Golden lancehead genome reveals how genes responsible for venom toxins evolved
A research team led by scientists at the Butantan Institute in São Paulo, Brazil, has completed the most extensive genetic sequencing of a jararaca viper to date. The focus of the study was the genome of the golden lancehead ...
Phys.org / Corpses leave clues behind in the soil long after they're gone
It is not uncommon for a body to be moved after a murder, usually to hide or eliminate evidence. And while the Arizona desert may seem like the perfect place to commit such a crime, a new study shows that a cadaver can still ...
Phys.org / Plants pause, play and fast-forward their growth depending on types of climate stress
Plants pause their growth during stress, then press play when conditions improve, helping them recover and live on to produce food, according to a new study published in New Phytologist. UBC researchers have pinpointed the ...
Phys.org / Titanium complexes cleanly edit the core skeleton of highly stable organic compounds
Multi-titanium hydrides can selectively snip the strong structural bonds of stable organic molecules called pyridines, RIKEN researchers have shown. This discovery could guide designing catalysts for applications in multiple ...
Phys.org / Flying 2,000 km to find a mate—meet Australia's most determined seabirds
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 ...
