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 / 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 / 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 / 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 ...
Phys.org / Watching quantum behavior in action: MagnetoARPES reveals time-reversal symmetry breaking in a kagome superconductor
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 ...
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 / Mangrove forests are short of breath, researchers warn
The tidal environment of mangrove forests serves as nurseries for many fish species. Researchers at the University of Gothenburg have measured carbon dioxide and oxygen levels in 23 of the world's mangrove areas. The study, ...
Phys.org / DNA barcoding reveals which gene-therapy nanoparticles reach targets in vivo
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 ...
Phys.org / 3D-printed rattlesnake reveals how the rattle is a warning signal
A team of researchers from The University of Texas at El Paso has uncovered new evidence explaining why the rattlesnake's rattle—one of nature's most iconic warning signals—has persisted and proven so effective across ...
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 / 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 / Simple 'cocktail' of amino acids dramatically boosts power of mRNA therapies and CRISPR gene editing
Lipid nanoparticles, or LNPs, best known as the delivery vehicle for the COVID-19 mRNA vaccines received by billions of people, are now at the center of a much larger medical revolution. Researchers are racing to use them ...
