Phys.org / Ancient Roman officers may have kept pet monkeys to highlight their status
There were many ways in which the elites of ancient Roman society flaunted their wealth. They built vast villas, sponsored extravagant games and imported luxury goods. And military top brass, at least those stationed at an ...
Phys.org / Massive non-cool-core galaxy cluster explored with Chandra
Astronomers have employed NASA's Chandra spacecraft to perform X-ray observations of a massive galaxy cluster known as SPT-CL J0217-5014. Results of the observational campaign, published December 4 on the arXiv preprint server, ...
Phys.org / New circoviruses discovered in pilot whales and orcas from the North Atlantic
A collaborative team of researchers has identified two previously unknown circoviruses in short-finned pilot whales and orcas from the Caribbean region of the North Atlantic Ocean. The findings represent the first detection ...
Phys.org / Roman urbanism was bad for health, new study confirms
Analysis of skeletal remains from England before and during Roman occupation confirms theories that the population's health declined under Roman occupation, but only in the urban centers, suggesting pre-Roman traditions continued ...
Phys.org / Mitochondrial enzyme's atomic-level structure reveals how it processes RNA
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, revealing how this essential ...
Phys.org / Study links vanishing of specific heats at absolute zero with principle of entropy increase
In a new publication, Professor José-María Martín-Olalla, from the Department of Condensed Matter Physics at the University of Seville, has described the direct link between the vanishing of specific heats at absolute ...
Phys.org / Earliest botanical art hints at prehistoric mathematical thinking
A new study published in the Journal of World Prehistory reveals that some of humanity's earliest artistic representations of botanical figures were far more than decorative; they were mathematical.
Phys.org / A pioneering study on the feasibility of asteroid mining
Much remains to be known about the chemical composition of small asteroids. Their potential to harbor valuable metals, materials from the early solar system, and the possibility of obtaining a geochemical record of their ...
Phys.org / New iron telluride thin film achieves superconductivity for quantum computer chips
If quantum computing is going to become an every-day reality, we need better superconducting thin films, the hardware that enables storage and processing of quantum information. Too often, these thin films have impurities ...
Phys.org / The evolutionary mysteries of a rare parasitic plant: Shrinking plastids and strange reproductive strategies
At the base of mossy trees, deep in the mountains of Taiwan and mainland Japan or nestled in the subtropical forests of Okinawa, grows what most might mistake for a mushroom—but it is actually a very unique plant with some ...
Phys.org / Iberian peninsula is rotating clockwise, according to new geodynamic data
Asier Madarieta, a researcher in the EHU's HGI (Water Environmental Processes) group, has analyzed how the Earth's crust is being compressed and deformed in the field where Eurasia and Africa meet in the Western Mediterranean. ...
Phys.org / Reddit field experiment examines what distinguishes lurkers from power users
Online discussions are often dominated by a small group of active users, while the majority remain silent. This imbalance can distort perceptions of public opinion and fuel polarization.
