Phys.org / Resilient quantum sensor monitors Earth's magnetic field from space for 10 months
From navigation to solar weather forecasting, many different areas of research require space-based sensors to measure Earth's magnetic field as accurately as possible at any given moment. So far, however, existing sensors ...
Tech Xplore / Governments may shape what AI chatbots say by shaping the web they learn from
Ask an AI model the same political question in two different languages, and you may get two very different responses. A new study in Nature suggests one reason why: governments can indirectly influence large language models ...
Medical Xpress / A two-way street: The overlapping world of premenstrual disorders and mental health conditions
Premenstrual disorders and psychiatric conditions often seem to flock together, and researchers now have data to make a case for it. A large Swedish study involving over 3 million women revealed a striking two-way path between ...
Phys.org / New alien-life test could help Mars and Europa missions read organic molecules
For decades, the search for life beyond Earth has revolved around a key question: What molecules should scientists be looking for on other planets or moons? A new study, published in Nature Astronomy, suggests that the more ...
Phys.org / Ancient iceberg scratches reveal reverse Great Lakes snowbelt
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt ...
Phys.org / New scenarios needed to address climate crisis, say scientists
Scientists, including those working with the Earth Commission, are calling for a fundamental rethink of how the world imagines its future, arguing that today's dominant climate and biodiversity models are too narrow to deal ...
Phys.org / When uncertainty spikes, chasing rewards backfires and a more informed strategy pulls ahead
Humans and other animals are constantly required to make decisions under uncertain conditions or while in rapidly changing environments. Past psychology and biology studies showed that some decision-making strategies can ...
Medical Xpress / Hantavirus: A cruise ship, a deer mouse and the fictional line between human and animal health
In February 2025, the classical pianist Betsy Arakawa died in her New Mexico home from a virus most people had never heard of. Her husband, the actor Gene Hackman, died a week later of heart disease. The pathogen that killed ...
Phys.org / What gives stevia its sweetness? Scientists uncover the genetic secret
Stevia is a widely used sweetener, but why do some stevia varieties taste cleaner and more sugar-like than others? Recent research conducted at the University of Toyama shows that stevia's sweetness is genetically linked ...
Tech Xplore / Prickly pear cacti show promise as the building materials of tomorrow
Researchers from the University of Bath's Department of Mechanical Engineering have shown that agricultural waste from prickly pear cactus plants could be used as a low-cost, low-carbon reinforcement for construction materials, ...
Phys.org / Meltwater flushed methane from Greenland seabed during ice-sheet retreat, researchers reveal
An international team of scientists has discovered that methane hydrates beneath the northwest Greenland continental shelf became rapidly destabilized by meltwater, releasing large stores of methane during ice-sheet retreat ...
Tech Xplore / Basalt could be the key to greener and cheaper cement
Ideas to reduce carbon emissions often revolve around renewable power, electric vehicles and energy efficiency. But there's another, less colorful character that's often overlooked: cement.
