Phys.org / Researchers tune into Arctic under-ice sounds and test through-ice communication
Beneath the Arctic Ocean is an orchestra featuring natural and human composers, from cracking sea ice and whistling beluga whales to humming shipping-vessel engines. Researchers from MIT Lincoln Laboratory heard some of this ...
Phys.org / Sound waves and water droplets transform paper waste into higher-value chemical compound
Researchers at the University of Illinois Urbana-Champaign have developed a fast, simple way to turn lignin, a plentiful plant-based byproduct of the papermaking industry, into potentially more valuable renewable chemicals.
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 ...
Medical Xpress / Cancer drug tames atherosclerosis inflammation and plaque in animal models
A new Yale study has identified a promising therapeutic avenue for atherosclerosis, a condition caused by inflammation and plaque buildup in arteries. Martin Schwartz, Ph.D., Robert W. Berliner Professor of Medicine (Cardiology) ...
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 / Salt may have helped turn Earth into a frozen world 700 million years ago
Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, when ice is thought ...
Phys.org / Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...
Medical Xpress / Early mitochondrial stress reveals potential mechanism for lasting heart protection
Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do much more—including acting as signaling hubs. Some signals that mitochondria send can reprogram the activity of the entire ...
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 / 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 ...
Medical Xpress / Rethinking radiotherapy may boost immunotherapy for pancreatic cancer
Pancreatic cancer remains one of the most aggressive malignancies, with a particularly poor prognosis even when diagnosed at a localized stage. In a paper published in Nature Reviews Gastroenterology & Hepatology, researchers ...
Tech Xplore / Brain activity patterns could help sharpen LLM deductive reasoning
Large language models (LLMs), the artificial intelligence systems underpinning the functioning of ChatGPT, Gemini and other similar conversational agents, are now widely used worldwide. In addition to processing, interpreting ...
