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 / 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 / Female aggression, not just mate choice, may speed mosquitofish speciation

A new study reveals that behavioral isolation between populations of Bahamas mosquitofish is driven primarily by the actions of females—not just through mating choice behaviors, but also through sometimes violent resistance. ...

Phys.org / Artificial kinetochores take the pressure off aging chromosomes during meiosis

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes becomes more prone to ...

Phys.org / Uncovering the hidden bacteria often mistaken for cholera

Scientists have created a genomic blueprint for Aeromonas bacteria, which can cause antibiotic-resistant diarrheal disease—with symptoms often misidentified as cholera—in humans and animals.

Phys.org / Fluid simulation at unprecedented scale provides toolkit for fundamental physics and applied fluid engineering

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at which a fluid filled ...

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 ...

Phys.org / Heavy water expands energy potential of carbon nanotube yarns

Researchers at The University of Texas at Dallas have developed a new electrolyte system that significantly boosts the energy-harvesting performance of twistrons, which are carbon nanotube yarns that generate electricity ...

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 / 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 / King penguins are the rare species benefiting from a warming world. But that could change

The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other—like flowers blooming too early and pollinating bees arriving too late. But researchers ...

Phys.org / Climate extremes hinder early development in young birds, research shows

New research from the University of Oxford shows that cold snaps and heavy rain can stunt growth and reduce survival prospects in UK great tit nestlings. However, breeding earlier within a season appears to buffer against ...
