Phys.org / CT scans of Inca child sacrifices reveal new details about capacocha rituals
The Incas were known to engage in a sacrificial ritual involving children to appease their gods. Archaeologists have found and analyzed the remains of these human sacrifices, although not all of them have undergone CT scanning, ...
Tech Xplore / Researchers pioneer next-generation AI semiconductors with 'thermal constraining' technique
A research team led by Professor Taesung Kim from the School of Mechanical Engineering at Sungkyunkwan University has developed a technology that precisely controls the internal structure of semiconductors using heat, much ...
Medical Xpress / Rising temperature may shift sex ratios at birth, analysis of five million births finds
"Temperature and sex ratios at birth," a new study led by researchers at the Department of Sociology at the University of Oxford and published in Proceedings of the National Academy of Sciences, provides new evidence that ...
Medical Xpress / Oxytocin-sensitive brain circuit may keep social bonds active under stress
The neuropeptide oxytocin is a special messenger substance that nerve cells use to communicate with each other. It is acting as both a neurotransmitter and a hormone and is best known for promoting social behavior. However, ...
Tech Xplore / Forest-based resins challenge fossil materials in wind turbines, boats and high-performance adhesives
Researchers at the University of Oulu, Finland, have developed new high-performance bio-based resins that can replace conventional oil-based materials in composite products—without compromising strength, cost, or industrial ...
Phys.org / Global greening: Study shows Earth's green wave is shifting northeast
A team of scientists led by the German Center for Integrative Biodiversity Research (iDiv), the Helmholtz Center for Environmental Research (UFZ), and Leipzig University has developed a new method to track Earth's greenness—a ...
Medical Xpress / Dry powder inhalers can improve patient outcomes and lower environmental impact
New research from UCLA Health suggests that certain inhalers used to treat chronic obstructive pulmonary disease (COPD) are not only less harmful to the environment but can also lead to slightly better patient outcomes. Inhalers ...
Medical Xpress / Online searches for crisis hotlines surged worldwide and rose in the same months as suicide-related searches
A new study analyzing global Google Trends data from January 2004 to August 2025 finds that online search interest in "crisis hotline" has increased sharply in recent years and tends to rise in the same months as searches ...
Phys.org / Scientists isolate climatic fingerprints of wildfires and volcanic eruptions
Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale. But picking out the specific impact of individual events against a background of many ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Phys.org / Jupiter's Galilean moons may have gained life's building blocks at birth
Southwest Research Institute was part of an international team that demonstrated how complex organic molecules (COMs), key chemical precursors to life, could have been incorporated into Jupiter's Galilean moons during their ...
Phys.org / Hair-width LEDs could eventually replace lasers
LEDs no wider than a human hair could soon take on work traditionally handled by lasers, from moving data inside server racks to powering next-generation displays. New research co-authored by UC Santa Barbara doctoral student ...
