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 / 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 / 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 / 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 / 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 / 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 / How volcanic eruptions and internal climate cycles jointly shape Asian monsoon rainfall
From the rice paddies of South Asia to the wheat fields of northern China, summer monsoon rains sustain the livelihoods of billions. Yet these vital rains fluctuate dramatically from decade to decade—a variability that ...
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 / Bromacker deposit is 4 million years older than previously thought, new dating reveals
Analysis of a volcanic ash tuff layer, only a few millimeters thick and discovered during excavations in 2024, revealed that the fossil-bearing Bromacker rocks are 294 million years old—four million years older than previously ...
Phys.org / Trouble swallowing? A nanogel tweak may keep therapeutic stem cells alive longer
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...
Phys.org / Friendly fungi hijack plant regulator to promote symbiosis
Plants are constantly on guard. Their roots are equipped with molecular alarm systems that detect invading microbes and trigger immune responses. Yet beneficial soil fungi routinely enter living root cells and establish close ...
Phys.org / What primate faces reveal about empathy: Humans mirror emotions across species
Humans perceive emotional expressions displayed by non-human primates and spontaneously mimic these expressions, according to a study published in the open-access journal PLOS One by Ursula Hess from Humboldt University of ...
