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 / Climate change puts riverbed microbes under constant stress, study finds
From tiny streams to gigantic rivers like the Mississippi—microbes in sediments work tirelessly to maintain key biogeochemical cycles. However, as temperatures rise, they tend to operate frequently in stress mode. This ...
Dialog / Quantum clues to consciousness: New research suggests the brain may harness the zero-point field
What if your conscious experiences were not just the chatter of neurons, but were connected to the hum of the universe? In a paper published in Frontiers in Human Neuroscience, I present new evidence indicating that conscious ...
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 / Spending less can deliver more climate-friendly nutrition
Eating healthily can save money and also cause less greenhouse gas emissions than most people's current food choices, according to a new global study that examined food costs, nutrition, and climate impact around the world.
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 / 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.
Phys.org / Lunar soil analyses reveal how space weathering shapes the moon's ultraviolet reflectance
Southwest Research Institute (SwRI) scientists are collaborating with researchers at UT San Antonio to study how space weathering can alter the lunar surface materials to help interpret regional and global far-ultraviolet ...
Tech Xplore / Tumbleweed aerodynamics inspire hybrid robots for harsh terrains
A new study published in Nature Communications details a hybrid robot that combines the wind-driven mobility of tumbleweeds with active quadcopter control, offering a new paradigm for energy-efficient terrestrial exploration.
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 new reference brain could make the clonal raider ant a go-to model species for neuroscience
Every clonal raider ant lives a nearly identical life. Each new generation of these blind, queenless ants is born at the same time, eats the same things, lives in the same environment, and—as an asexually reproducing species—has ...
Medical Xpress / Stress hormones can alter brain networks and strengthen emotional memories
Stress influences what we learn and remember. The hormone cortisol, which is released during stressful situations, can make emotional memories in particular stronger. But how exactly does cortisol help the brain build emotional ...
