Phys.org / NASA-JAXA XRISM finds elemental bounty in supernova remnant
For the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft.
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 ...
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 / 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 / The race to mine the Moon is on, and it urgently needs some clear international rules
The vision of mining space for resources is no longer science fiction. The moon's proximity to Earth and the presence of precious resources make it an increasingly attractive prospect for exploitation.
Medical Xpress / Drug resistance in pancreatic cancer: Scientists pinpoint major and minor signaling pathways that drive it
Cancer drug resistance is the devastating reason that treatments fail and cancers metastasize, spreading to distant sites seeding new resistant tumors elsewhere in the body.
Phys.org / Chemical traces of 2023 Canadian wildfires detected in Maryland months after smoke subsided
In 2023, Canada's worst wildfire season on record produced so much smoke that it spilled across national borders into the United States. At times, a thick haze enveloped much of the U.S. East Coast and triggered "Code Purple" ...
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 / 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 ...
Medical Xpress / Genetic overlap of 14 psychiatric disorders explains why patients often have multiple diagnoses
An international collective of researchers is delivering new insights into why having multiple psychiatric disorders is the norm rather than the exception. In a study published today in the journal Nature, the team provides ...
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 / 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.
