Phys.org / In ant nervous systems, gene expression may drive rescue behavior
Why do some ants help nestmates in distress while others don't? A research team from Johannes Gutenberg University Mainz (JGU) and Tel Aviv University addressed this question in a new study. The researchers examined worker ...
Phys.org / New AI tool maps the hidden universe of small molecules
The human body and its gut microbiome produce thousands of small molecules that shape how the body functions—influencing immunity, metabolism and more. Identifying what those molecules actually are has been one of the biomedical ...
Phys.org / Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductors
Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that ...
Phys.org / Archaea as 'flexitarians': Ammonia-oxidizing microbes also feed on amino acids
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration ...
Phys.org / Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials
A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coating the surfaces of magnetic-insulator powders ...
Phys.org / Turbulent times for star formation in Stephan's Quintet
Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing dense clouds to collapse under their own gravity ...
Phys.org / Davyne changes color beyond human sight, opening path to invisible security tags
While studying the properties of hackmanite, researchers created a new material called davyne that changes color in the near-infrared region. The color change cannot be detected with the human eye, but only with a spectrometer ...
Phys.org / 'Hidden order in disorder' makes nanodevices easier to design
Augmented reality (AR) glasses, lenses thinner than a human hair, and holograms floating above your fingertips may sound like technologies from science fiction. At the heart of these emerging technologies, however, lies a ...
Phys.org / AI-driven polymer discovery could replace years of trial and error with closed-loop testing
In the realm of materials science, there is a plethora of datasets and tools at our disposal—the issue is how to effectively use these resources in harmony. Researchers at the Advanced Institute for Materials Research (WPI-AIMR), ...
Phys.org / Physics-informed AI improves predictions of how critical minerals move through rock
The key to finding more critical minerals may lie in understanding how fluids and chemicals move through rock. As these fluids travel underground, they can dissolve, transport and concentrate valuable minerals in specific ...
Phys.org / Can a full moon really bring bad luck? What about Friday the 13th?
Jeffrey Rosenthal was a young professor at the University of Toronto when he discovered he was born on a Friday—though not just any Friday.
Phys.org / Since the 1980s, climate change has increasingly altered European bumblebee habitats
Global biodiversity loss is occurring at a rapid pace, driven by multiple human-caused factors, including overexploitation, pollution, invasive species and climate change. Despite increasing research on the impact of climate ...
