Phys.org / Ancient Rome's food shortages were shaped more by logistics than climate
Ancient Rome's greatest threat to food security wasn't the weather but the challenge of getting grain to the capital, according to a new study. By comparing hundreds of years of historical records with reconstructions of ...
Phys.org / Suspected heatstroke kills three lions at Japan zoo
Three lions at a Tokyo zoo have died from suspected heatstroke, and others are under treatment, a spokeswoman said Tuesday, with the big cats struggling with high humidity.
Phys.org / Less-explored form of quantum code could be more powerful—and more stable—than its alternative in error correction
In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first). ...
Phys.org / Two independent studies push semiconductor qubits towards practical scales
Semiconductor spin qubits are one of the most promising building blocks for future quantum computers, but turning them into a working, large-scale quantum computer has so far proven difficult. For now, two big questions remain ...
Phys.org / Smart sensor identifies present molecules by remembering the past
Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration. If ...
Phys.org / An ancient civilization of millions once flourished in the Amazon
New research conducted using airborne laser scanning reveals that a multicultural civilization that flourished in southwestern Amazonia between 600 BCE and 850 CE was home to millions of people. Spanning roughly 183,000 square ...
Phys.org / Quantum computer completes verified task beyond practical reach of classical simulations
IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for "quantum advantage"—the point where quantum computers can be confirmed to have outperformed ...
Phys.org / Why some nitrogen-processing enzymes are more efficient than others
Nitrogen gas is abundant in Earth's atmosphere, but most living organisms can't readily use it. Only a subset of microbes with enzymes known as nitrogenases can break nitrogen gas apart and convert it into ammonia.
Phys.org / AI opens new era in cognitive studies of wild primates
Scientists created an AI system that uses facial recognition and real-time touchscreen testing to automate cognitive studies of capuchin monkeys in the wild. The American Journal of Primatology published a proof-of-concept ...
Phys.org / Climate change could dramatically reduce water flowing from the West's headwaters
The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across ...
Phys.org / Pacific cloud brightening could weaken El Nino, but models reveal risks for Europe and Asia
A brewing "super" El Nino cycle is poised to unleash heat waves, floods and drought worldwide, with the effects amplified by long-term human-caused climate change.
Tech Xplore / Existing power grids draw data centers to cities, study finds
When people picture a data center, they often imagine something remote: a huge warehouse humming quietly far from the city. New research from NYU Tandon School of Engineering shows that assumption is largely wrong.
