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 / 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 / New research shows path to affordable water in fast-growing cities
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 ...
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 ...
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 / Still standing but mostly dead: Recovery of dying coral reef in Moorea stalls
In April 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. This "bleaching" event reduced live coral populations ...
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 / Acoustic driving enables controlled condensation of light and matter on chip
An international research team led by Alexander Kuznetsov at the Paul Drude Institute for Solid State Electronics (PDI) in Berlin has demonstrated a fundamentally new way to control the condensation of hybrid light-matter ...
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 ...
Phys.org / North Sea 'lost world' had habitable forests during the last Ice Age, study shows
Forests were growing on the now-submerged landmass of Doggerland thousands of years earlier than previously believed, according to a major new sedimentary ancient DNA (sedaDNA) study led by the University of Warwick. The ...
