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 / 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 / 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 / Airborne sensors map ammonia plumes in California's Imperial Valley
A recent study led by scientists at NASA's Jet Propulsion Laboratory in Southern California and the nonprofit Aerospace Corporation shows how high-resolution maps of ground-level ammonia plumes can be generated with airborne ...
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.
Phys.org / Light-controlled embryos reveal power of mechanical forces in human development
Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, a flat and featureless ...
Phys.org / Generative chatbots promise personalized education at scale but struggle with accuracy issues
Personalized learning is a very effective teaching method, but its potential is limited due to resource constraints. In a small, in-person class, instructors can walk around, engage with students individually, adjust lessons ...
Phys.org / From light to logic: First complete logic gate achieved in soft material using light alone
Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of visible light. The ...
Phys.org / Hidden process behind 2025 Santorini earthquakes uncovered
A mysterious swarm of earthquakes that occurred near the Greek island of Santorini in early 2025 was caused by rebounding sheets of magma slicing through Earth's crust, according to a new study by an international team involving ...
Phys.org / Not just stomata: Hidden water regulation mechanism could help crops survive drought
Cornell researchers have discovered a previously unknown way plants regulate water that is so fundamental it may change plant biology textbooks—and open the door to breeding more drought-tolerant crops.
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 / 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 ...
