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 / Ancient burial practices emerge from Laos' mysterious Plain of Jars
Hundreds of stone jars, some weighing several tons, are scattered across the remote uplands of northern Laos. Despite being researched for nearly a century, their purpose remains uncertain. "Archaeologists generally agree ...
Phys.org / Careful crystallization unlocks well-ordered perovskite layers for transistors
Perovskites are a class of materials with a unique crystal structure that suits applications such as fabricating solar cells, light-emitting diodes and transistors. However, molecules in thin layers often cannot arrange themselves ...
Phys.org / Prototype sets record for optical quantum information technology
Chinese scientists have developed a programmable quantum computing prototype called Jiuzhang 4.0 that has set a new world record for optical quantum information technology, according to a study published May 13 in the journal ...
Phys.org / Mapping how 'Big AI' influences AI laws and oversight
Artificial intelligence (AI) companies influence policy and regulation using similar techniques to Big Tobacco, Big Pharma and Big Oil, according to a new study.
Phys.org / Reconfigurable Ge-Si photodetector achieves ultrahigh-speed data transmission using low-loss packaging
The rapid growth of large language models is placing increasing demands on data centers, where large volumes of data must be transferred efficiently between servers. Optical interconnects are essential for enabling this communication, ...
Phys.org / Eyes that photosynthesize: Scientists plant a cure for dry eye disease
What if eyes could use light to heal themselves? Drawing inspiration from how plants harness sunlight, researchers at the National University of Singapore (NUS) are pioneering a revolutionary treatment for dry eye disease. ...
Phys.org / 370 billion crickets are farmed for food every year. Scientists have discovered they may feel pain
You're cooking dinner, distracted, and your hand brushes a hot pan. Nerve signals race to your spinal cord and back to yank your arm away in a fraction of a second, with no thought required.
Phys.org / Even after adopting cattle, early east African herders kept hunting and gathering for 1,000 years
Eastern Africa's earliest livestock herders continued fishing, hunting and gathering for centuries after livestock were first brought to the region. The first pastoralists in eastern Africa didn't suddenly switch to a diet ...
Phys.org / Learning physics can derail some students: New research shows the best way to keep them on track
For many undergraduate students, exploring the complexities of physics for the first time, from wading through advanced mathematics, to absorbing information in a large lecture format, can be a daunting endeavor—one that ...
Phys.org / MatterChat model helps AI to 'see' the language of atom-scale physics to sharpen materials predictions
From writing emails to generating computer code, much of the artificial intelligence prevalent in our daily lives has succeeded by mastering one domain: text. However, this leaves a major blind spot in the physical sciences, ...
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 ...
