Phys.org / A smelly dog breath breakthrough: Plant-based spray tackles odor and harmful oral microbes
Pet owners love their dogs but may not always love the smell of their breath. Because this bad odor can signal oral disease, veterinary clinics will prescribe daily toothbrushing, antibiotics, or chemical rinses as treatment. ...
Phys.org / A physicist's fresh look at the 'prisoner's dilemma' reveals hope for cooperation
The "prisoner's dilemma" is one of the most famous ideas in game theory. For decades, this game has been used to explain why selfishness often beats cooperation. In the prisoner's dilemma, two players can either cooperate ...
Phys.org / Elongated canopy gaps may best support the natural regeneration of oak forest
As climate change intensifies, one of the key challenges facing forestry is how to balance efficient timber production with the preservation of forests' climate-regulating functions, biodiversity, and resilience. The growing ...
Phys.org / Climate adaptation may drive gentrification across African cities, continent-scale analysis shows
Green-blue adaptation (climate adaptation based on green and water spaces), which uses green and water spaces such as creating urban parks and restoring wetlands, is considered a representative climate adaptation strategy ...
Phys.org / Behold the neuron, a complicated cell with a simple mission
Neurons, the uber-connected nerve cells that act as a main switchboard for the brain, are central to some incredibly complicated processes. They make it possible to think, walk, speak, and breathe. They even have built-in ...
Phys.org / This single mother must learn quickly—or her colony won't survive
Being a single mother of 20 is no joke, especially if the survival of a whole species depends on it. A queen bumblebee faces this very challenge when she lays her first eggs in the spring: She is utterly alone, with no worker ...
Phys.org / How wasted infrared light could boost solar panels, night vision and 3D printing
Researchers at UNSW Sydney have developed a nanoscale device that converts low-energy infrared and red light into higher-energy visible light, a breakthrough that could eventually improve solar panels, sensing technologies, ...
Phys.org / You are what you eat: Cichlid fish reveal how food sources drive evolution of digestive system
Different beak and jaw shapes are illustrative examples of how animal species have adapted to different food sources. In a new study published in the journal Nature, researchers now show how diet itself shapes the composition ...
Phys.org / Indian and Tibetan wolves reveal ancient lineages with unexpected genomic diversity
Wolves in India, like the pack that raised Mowgli in "The Jungle Book," can often feel disconnected from both the research and storytelling of wolves. Rice University professor Lauren Hennelly is working to change that. Her ...
Phys.org / New evidence reveals a millennium-old dingo was ritually buried, and cared for, in Australia
A millennium-old dingo deliberately buried by Barkindji ancestors along the Baaka, or Darling River, is offering rare insight into the depth of relationships between First Nations people and dingoes in western New South Wales, ...
Phys.org / From wetland sediment, scientists uncover centuries of climate chaos—and human resilience
The climate of the ancient Eastern Mediterranean was far more turbulent than previously thought—and a new study suggests that people adapted anyway. An international team of scientists, spearheaded by UC San Diego's Center ...
Phys.org / Policing plagiarism of ideas in generative AI-assisted research writing
As more people—including researchers—use generative artificial intelligence (GenAI) in their writing, it's becoming increasingly important to define what plagiarism looks like and how to police it.
