Phys.org / A new type of lion roar could help protect the iconic big cats
A new study has found African lions produce not one, but two distinct types of roars—a discovery set to transform wildlife monitoring and conservation efforts.
Phys.org / Want to make new friends? Take a lesson from these birds
Making new friends has its challenges, even for birds. Researchers at the University of Cincinnati found that monk parakeets introduced to new birds will "test the waters" with potential friends to avoid increasingly dangerous ...
Phys.org / Over a decade in the making: Lanthanide nanocrystals illuminate new possibilities
In a discovery shaped by more than a decade of steady, incremental effort rather than a dramatic breakthrough, scientists from the National University of Singapore (NUS) and their collaborators demonstrated that great ideas ...
Phys.org / Back to the beach: Why did evolution return some animals to the water?
In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip. Dozens of major mammal and ...
Phys.org / Rethinking where language comes from: Framework reveals complex interplay of biology and culture
A new study challenges the idea that language stems from a single evolutionary root. Instead, it proposes that our ability to communicate evolved through the interaction of biology and culture, and involves multiple capacities, ...
Phys.org / Quantum calculations expose hidden chemistry of ice
When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades.
Phys.org / Watching gold's atomic structure change at 10 million times Earth's atmospheric pressure
The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties. Understanding matter in this ...
Phys.org / Could the solution to the carbon problem be carbon itself?
Can we use carbon to help decarbonize the world and transform the energy and chemical industries? Yes, it seems, but there are some key challenges to overcome first.
Phys.org / Smart toilets in Cambodia fall short due to improper use
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was ...
Phys.org / Mystery of how turtles read their magnetic map solved—they feel the magnetism
Loggerhead turtles are able to sense Earth's magnetic field in two ways, but it wasn't clear which sense the animals use to detect the magnetic field when navigating using the magnetic map they are born with. Now researchers ...
Phys.org / Extinct rocket frog species identified from single 62-year-old museum specimen
Anyone walking through the Tarumã neighborhood in Curitiba (the capital of the state of Paraná, Brazil) today may find it difficult to imagine the area as it was in the past. Between the buildings, racetrack, and the city's ...
Phys.org / NASA's Roman could bring new waves of information on galaxy's stars
A team of researchers has confirmed stars ring loud and clear in a "key" that will harmonize well with the science goals and capabilities of NASA's upcoming Nancy Grace Roman Space Telescope.
