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 / Study maps the time and energy patterns of electron pairs in ultrafast pulses
The ability to precisely study and manipulate electrons in electron microscopes could open new possibilities for the development of both ultrafast imaging techniques and quantum technologies.
Phys.org / Bringing environmental policymakers together to focus on future sparks empathy, study finds
When environmental policymakers are invited to imagine the future together, they don't just think differently, they feel differently, too.
Phys.org / Y1 is an ultra-luminous infrared galaxy, ALMA observations reveal
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has inspected a distant galaxy designated MACS0416_Y1. Results of the observations, presented Nov. 11 on the arXiv pre-print ...
Phys.org / Video catches wild wolf pulling in crab trap to get to food—but is it tool use?
Many animals have been observed using tools. For example, chimps tear leaves off of branches and stick them into holes to pull out termites, and wild dingoes have been observed moving objects to stand on to get to another ...
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 / 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 ...
Tech Xplore / New green homes in the UK put less strain on the grid than models predicted
A study of some of the first net-zero-ready homes in the UK has found that their peak grid power demand is far lower than planners had anticipated. The research confirms that these all-electric homes can significantly cut ...
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 / 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 / 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 / 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 ...
