Phys.org / Physicists link the Riemann Hypothesis to phase transitions in quantum systems
A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor.
Phys.org / New technique pinpoints human DNA inherited from 'ghost' ancestors
UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.
Phys.org / Rideshare launches boost regional GDP and flexible jobs, study finds
Ride-hailing has become a routine part of urban life in the United States, but its broader economic impacts have been difficult to measure. As Uber and Lyft expanded across hundreds of cities over the past decade, they promised ...
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 / New photonic platform offers a four-lane highway for light
Topological photonics can force propagating light to travel in a single direction—allowing researchers to route optical signals around corners and past defects without any of it scattering backward. So far, however, this ...
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 / Insights into bee biology could ease US rules for organic honey
Strict regulations have prevented continental U.S. beekeepers from participating in the lucrative organic honey market, but new research finds that bees' actual habits make certain rules too extreme. The findings potentially ...
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 ...
Medical Xpress / Not all exercise is equal when it comes to metabolic syndrome risk
Not every disease announces itself with obvious symptoms. Some develop quietly, going unnoticed until they begin to take a serious toll on health. Metabolic syndrome (MetS) is one of them. Rather than a single disease, it ...
Phys.org / New immune-blocking strategy improves interspecies organ generation
Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages ...
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 ...
Medical Xpress / Scientists restore lost protein to reverse lung disease in preclinical models
Researchers at the Fralin Biomedical Research Institute at VTC have identified a natural protective protein that maintains healthy lung blood vessels. Increasing the expression of this protein in preclinical models of pulmonary ...
