Around 1,000 years ago, a major climate shift reshaped rainfall across the South Pacific, making western islands like Samoa and Tonga drier while eastern islands such as Tahiti became increasingly wet. New evidence from plant waxes preserved in island sediments shows this
A new report warns Deaf women experiencing domestic abuse in Scotland remain "effectively invisible" due to the chronic absence of specialist services and a lack of coordinated national support. Researchers say this gap leaves deaf victim-survivors without meaningful access to
Giant mosasaurs, once thought to be strictly ocean-dwelling predators, may have spent their final chapter prowling freshwater rivers alongside dinosaurs and crocodiles. A massive tooth found in North Dakota, analyzed using chemical isotope techniques, reveals that some
Air pollution is the latest environmental crisis causing havoc across Iran. Large parts of the country are already suffering from a drought, one of the worst in decades. Its wetlands are dry, and its land is subsiding at alarming rates.
Congress appears poised to spend money in 2026 on beach replenishment projects in wake of the zero dollars it allocated this year.
New data released today from one of the world's longest-running wildlife surveys show Australia's waterbird population made a partial return after last year's steep drop, but numbers remain well below historic levels.

When you next bite into a chicken sandwich, consider this: 2,400 of these birds are being slaughtered somewhere in the world every second. From street stalls in Mumbai to supermarkets in Beijing, chicken has become the world's most consumed meat. In 2023 alone, humans
Although all children have a right to education, many arrival centers for refugees offer little or no access to education, concludes a study by Johanna Funck (University of Bremen) and Markus Ciesielski (htw saar).
At the heart of every camera is a sensor, whether that sensor is a collection of light-detecting pixels or a strip of 35-millimeter film. But what happens when you want to take a picture of something so small that the sensor itself has to shrink down to sizes that cause the
People often see science as a world apart: cool, rational and untouched by persuasion or performance. In this view, scientists simply discover truth, and truth speaks for itself.
The water that flows down irrigation canals to some of the West's biggest expanses of farmland comes courtesy of the federal government for a very low price—even, in some cases, for free.
Doenjang is a traditional Korean fermented soybean paste made from meju—naturally fermented soybean blocks—mixed with salt and aged through long-term fermentation. Unlike Japanese miso, Korean doenjang does not use koji; its flavor develops entirely from the natural

The holiday season sparks a significant increase in consumer spending. This year, Black Friday alone saw consumers shell out a record US $11.8 billion. It's the time of year when many Americans make purchases to decorate for the holidays—lights, ornaments and Christmas trees.
Carl Sagan famously said that "We're all made of star stuff." But he didn't elaborate on how that actually happened. Yes, many of the molecules in our bodies could only have been created in massive supernovae explosions—hence the saying—and scientists have long thought they had
Learning to read is a complex process. It requires children to master and integrate multiple skills, from mapping abstract symbols to the right speech sounds to understanding what all the words mean. This is why reading is one of the first and most important things children are
