Phys.org / When Earth's magnetic field took its time flipping
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are called geomagnetic reversals, ...
Medical Xpress / Brain 'fingerprints' are less unique in major depressive disorder, study suggests
Major depressive disorder (MDD) is a debilitating condition that affects more than 246 million people worldwide, yet scientists have struggled to identify consistent brain markers that could improve diagnosis and treatment. ...
Phys.org / Natto fermentation actively produces health-promoting supersulfide molecules, study reveals
Supersulfide molecules, metabolites from plants that are important in cellular metabolism, are attracting attention in the medical and nutritional fields for their potential in supporting health and disease prevention. Natto, ...
Phys.org / The compleximer: New type of plastic mixes glass-like shaping with impact resistance
Researchers at Wageningen University & Research have developed a new type of plastic that, according to materials theory, should not be able to exist. Its properties sit somewhere between those of glass and plastic: it is ...
Tech Xplore / GeSn alloys emerge as a new semiconductor class that could reshape optoelectronics
Scientists have created a new type of material that could enable common electronic devices to work faster and use less energy, a study suggests. The findings indicate the material, which was until now thought near-impossible ...
Phys.org / Pittsburgh study links dark roofs and roads to higher heat and social vulnerability
Cities are increasingly becoming the epicenter of climate-related risks, with research showing that impervious surfaces (e.g., roofs, streets, sidewalks, parking lots) are a major driver of urban climate impacts because they ...
Medical Xpress / How shift work and irregular eating impact your liver body clock
Shift work and irregular eating patterns could affect liver function and disrupt its delicate circadian rhythm, University of Queensland researchers have found. Dr. Meltem Weger from UQ's Institute for Molecular Bioscience ...
Tech Xplore / AI agents debate more effectively when given personalities and the ability to interrupt
In a typical online meeting, humans don't always wait politely for their turn to speak. They interrupt to express strong agreement, stay silent when they are unsure, and let their personalities shape the flow of the discussion. ...
Medical Xpress / New medication may reduce chances of a second clot-caused stroke without bleeding risk
An investigational anti-clotting medication, asundexian, has demonstrated a reduction in the risk of a second ischemic (clot-caused) stroke without raising bleeding concerns, according to a preliminary late-breaking science ...
Phys.org / Increasing pesticide toxicity threatens global biodiversity protection goal: Only one country is currently on target
At the 15th UN Biodiversity Conference (COP15) in Montreal, Canada, in 2022, nations committed to reducing the risks associated with pesticide use in agriculture by 50% by 2030. A new study by a research team from RPTUKaiserslautern-Landau, ...
Phys.org / Philadelphia communities help AI machine learning get better at spotting gentrification
Over the last several decades, urban planners and municipalities have sought to identify and better manage the socioeconomic dynamics associated with rapid development in established neighborhoods. The term "gentrification" ...
Phys.org / Global map catalogs 459 rare continental mantle earthquakes since 1990
Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in our planet's mantle, the layer sandwiched between the thin crust and Earth's molten core. The new ...
