As NASA's Curiosity rover recently began climbing a Martian valley nicknamed "Valle Grande," it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each about ...

For decades, a 30 million-year-old fossil sat entombed in rock in an Oregon museum collection. When it was first found, paleontologists thought it might be an early relative of sheep, camels and pigs, whose fossilized skeletons ...

Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...

Researchers at the University of Bath and The London School of Economics and Political Science (LSE) suggest that the celebrated Dunning-Kruger effect, often taken to mean the least competent people are the most overconfident, ...

Deploying ocean iron fertilization—a strategy for carbon dioxide capture—in higher latitudes rather than near the equator could reduce environmental impacts while still achieving removal of carbon dioxide from the atmosphere, ...

In the words of a former Antarctic tour guide we interviewed: "You'd see massive glacier calvings, and you'd just want to cry. But all the guests would be cheering. And you'd be like … 'can you not put two and two together?'"

Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with ...

Scientists have uncovered an ancient population previously unknown to science in Ladakh, a high-altitude region in northern India. Their studies revealed individuals with a nearly perfect 50–50 mix of South Asian-related ...

Pennsylvania's roughly 100,000 oil and gas wells produce wastewater that's many times saltier than seawater and contains radium, a known carcinogen. For decades, that saltwater, called brine, was spread on dirt and gravel ...

Around a quarter of the U.S. food supply is grown in California's Central Valley. Most of its crops, like rice, fruit trees and nut trees, are water-intensive and require extensive groundwater pumping during droughts. Over ...

At long last, astronomers have firm evidence that Betelgeuse, one of the most famous stars in the night sky, is not alone. Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team led by French researcher ...

Ancient footprints preserved along the shores of Kenya's Lake Turkana are reshaping scientists' understanding of one of humanity's extinct relatives. A paper published in Proceedings of the National Academy of Sciences describes ...
