Quantum technologies promise powerful new kinds of computers, giving scientists new tools to mimic and explore nature at its tiniest scales. At those levels, everything in nature—from atoms and electrons to light itself—follows the strange rules of quantum mechanics. But the
We often assume that how we respond to a rude comment says something stable about us: our personality, our culture, even the language we are speaking. If someone reacts calmly, we presume they are a patient person. If they snap back, we might assume they are short-tempered.
What happens when a scientific problem seems too complex to solve precisely, yet understanding it could reshape how researchers design new materials and medicines? For decades, much of the polymer science community has relied on a "good enough" approach to a stubborn problem:
How well do language models understand Meenzerisch, the dialect spoken in the German city of Mainz? A research team led by Johannes Gutenberg University Mainz (JGU) has now investigated this question for the first time. Meenzerisch still shapes regional language culture today
You skip the pesticides, you remove weeds by hand, you choose heirloom seeds. Organic methods give you comfort in knowing that your vegetables are grown without excessive chemicals.
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control of the wealth and the gap between rich and poor
Scientists at VIB and Vrije Universiteit Brussel have uncovered a previously unknown mechanism that helps a widely used biological pesticide become more effective. The study, published in Nature Communications, reveals how bacteria produce ultra-strong protein fibers that form
Economists have identified—and resolved—a seeming paradox regarding how competition from China affects the price and volume of products that are exported from other countries into the United States. The findings shed new light on the complex dynamics of international trade and
The practice of freediving is teaching physiologists how humans stretch their physical and mental limits, which in turn may improve treatments for lung and heart ailments.
A new European-led telescope could map the dusty, hidden half of the universe, all without using fossil fuels. If you have ever seen the Milky Way in the night sky, you probably noticed that it looks cloudy. That is because towards the center of our galaxy, and of most
When I first became co-director of an archaeological project at Jebel Barkal in northern Sudan in 2018, I was amazed by the site's pyramids, temples and palaces. It had been an urban center in the ancient empire of Kush, which dominated the Nile Valley off and on for more than
Formula 1 auto racing is one of the most energy-intensive and logistically complex sports on the planet. The events involve cars, of course, but also long-haul freight, international travel, temporary event infrastructure, and a global calendar that keeps people and equipment
A large-scale analysis of Grokipedia, the world's first AI-written encyclopedia, has found that while many Grokipedia articles closely resemble their Wikipedia counterparts, a substantial subset diverged markedly in style, sourcing and political leaning.

Holding off on that late-night online order of a book, blender or blue jeans could ease the strain on a warehouse worker. Consumers' around-the-clock, often impulsive demand for cheap, rapidly delivered products creates harsher working conditions in e-commerce fulfillment
In every organism, the regulation of cell populations is a constant process. This balance relies on a continuous interplay between "guardian" proteins that promote cell survival and "killer" proteins that trigger programmed cell death, known as apoptosis. Any disruption of this
According to NOAA, the global average sea level has risen 8–9 inches (21–24 centimeters) since 1880. The rate at which the sea level is rising is increasing, threatening coastal cities and ecosystems around the world.
The pre-print website arXiv has announced that researchers who put their names to papers which included errors clearly generated by artificial intelligence (AI) will face a year-long ban and ongoing restrictions.
Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often neglected—a fact that Bayreuth doctoral researcher Frederik Gareis already
It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts like a giant conveyor belt, moving warm surface water
An AI trained to use thermal images to detect whale body heat could help warn ships at risk of colliding with the marine mammals.
Some animals can move efficiently beneath granular surfaces. These include the sandfish (Scincus scincus), a lizard native to the Sahara. It can burrow into the sand and then literally "swim" through the desert sand to hunt or escape predators.
As space missions travel farther from Earth, spacecraft must increasingly be able to process and store their own data. Soon, artificial intelligence (AI) could be the primary tool for handling this growing volume of information.
The sudden resolution of a well-known conjecture highlights the growing adoption of AI as an assistant in high-level mathematics
