A University of Calgary archaeologist has found evidence that the Classic Period Maya were trading live dogs over long distances between the northern Yucatan peninsula and central Chiapas regions.
Tech Xplore / Focused helium ions create ferroelectric regions in aluminum nitride for lower-power chips
Scientists at the Department of Energy's Oak Ridge National Laboratory have shown for the first time that ferroelectricity can be directly written into aluminum nitride using a tightly focused helium ion beam at the Center ...
Phys.org / Harmless viruses trap Salmonella on flexible polymer in portable microfluidic sensor
Researchers at Worcester Polytechnic Institute (WPI) have developed a solid polymer coated with harmless viruses to detect the bacteria Salmonella enterica (S. enterica), an advance that could lead to new ways of finding ...
Phys.org / Thawing Arctic soil awakens only half of soil microbes, new study reveals
As the Arctic warms at an unprecedented rate, frozen soils that have remained locked in ice for most of the year are now thawing for longer periods. Yet new research led by an international team including scientists from ...
Phys.org / Climate-driven extreme fire danger cannot be prevented by carbon neutrality alone, study warns
A new study warns that unless atmospheric carbon is reduced immediately, future summers will become even hotter and future wildfires even more destructive. A research team led by Professor Seung-Ki Min of the Department of ...
Dialog / Scientists uncover hidden parasite diversity in barb fish from the Sea of Galilee
When most people think about biodiversity in lakes and rivers, they imagine fish, plants, or perhaps birds and amphibians. But beneath the surface exists another world that often goes unnoticed: microscopic parasites that ...
Medical Xpress / AI language models struggle with basic hospital data tasks, study finds
A new study finds that large language models (LLMs), used with straightforward prompting, perform poorly on routine number-crunching tasks that hospital administrators depend on every day to track patients and allocate resources. ...
Medical Xpress / Leukemia stem cells cause treatments to fail, but findings open new avenues to overcome resistance
Scientists from the German Cancer Research Center (DKFZ) and the HI-STEM Stem Cell Institute have deciphered a key mechanism that contributes to treatment failure in acute myeloid leukemia (AML). They show that there are ...
Medical Xpress / Garlic-derived compound shows potential to improve muscle health during aging
Can a compound derived from a common kitchen ingredient help support muscle health during aging? A new study suggests it can. The study reveals that S-1-propenyl-L-cysteine (S1PC), a bioactive compound found in aged garlic ...
Medical Xpress / Scientists finally see inside the 'black box' of depression treatment
Transcranial magnetic stimulation (TMS) is a noninvasive, FDA-approved therapy that uses brief magnetic pulses to treat depression, particularly in patients who do not respond to medication. Yet scientists have long struggled ...
Phys.org / Gaming monkeys' curiosity: Japanese macaques actively explore moderately uncertain stimuli
The intrinsic information-seeking impulse we call curiosity is independent of extrinsic rewards, such as food or mating opportunities. Curiosity is purely the pursuit of understanding the unknown, driving both humans and ...
Phys.org / Optically dark gamma-ray burst reveals an unusually wide jet
Using various telescopes, an international team of astronomers has performed multi-wavelength observations of a recently identified gamma-ray burst source designated GRB 250416C. Results of the observational campaign, published ...
