Refugees from Ukraine who suffer from potential war trauma are less likely to work than their compatriots who do not. This is the result of a study published as an RFBerlin discussion paper.
For years, satellite data suggested that autumn snow cover in the Northern Hemisphere was actually increasing — a surprising twist in a warming world. But a new analysis reveals that this apparent growth was an illusion caused by improving satellite technology that became
Northern Japan, especially the island of Hokkaido, is home to some of the snowiest cities in the world. Sapporo, the island's largest city and host of an annual snow festival, typically sees more than 140 days of snowfall, with nearly six meters (20 feet) accumulating on
Imagine someone has chronic pain. One doctor focuses on the body part that hurts and keeps trying to fix that single symptom. Another uses a more comprehensive brain-body approach and tries to understand what's keeping the nervous system stuck in alarm mode—perhaps stress, fear
Scientists in China have unveiled a breakthrough way to mass-produce powerful cancer-fighting immune cells in the lab. By engineering early-stage stem cells from cord blood—rather than trying to modify mature natural killer (NK) cells—they created a streamlined process that
The value of wetlands on the landscape cannot be overstated—they store and filter water, provide wildlife habitat, cool the atmosphere and sequester carbon. Yet, in the farmland area of Canada's Prairies, wetlands are being drained to increase crop production and expand urban
It's long been assumed the Jomon people, who had inhabited the Japanese archipelago since around 16,000 years ago, had multiple lineages resulting from different migration routes. But new genetic evidence, including mitochondrial DNA from 13 newly sequenced Jomon skeletons,
What does it mean to love your job? The language of love has become increasingly common in contemporary discussions of work. People say they want to love their jobs, organizations promise roles candidates will love, and recruitment ads frame employment as an emotional
Frank Cuozzo and Michelle Sauther first traveled to South Africa in 2012 to search for some of the most unusual primates on Earth—bushbabies. These animals are nocturnal and small, often around the size of a housecat. Bushbabies have big ears, round eyes and get their names
Thousands of people were killed by Iranian security forces in days of protests in January 2026. Meanwhile, in the same month, the killing of two protesters in Minneapolis shone a light on the use of fatal force by American law enforcement—a phenomenon that in 2025 saw the
The role of soil and forests in greenhouse gas sequestration has been studied for a long time. However, forests are also home to invisible organisms that may affect the climate. "Soil, water and peatlands have been studied in the Biogeochemistry Research Group at the University
Most Hawaiʻi residents believe sea level rise is already affecting the state, expect major impacts within their lifetimes, and support significant changes to how and where development occurs. At the same time, many remain uncertain about how large-scale adaptation should be
Yesterday, an international team of researchers from various disciplines set off aboard the German research vessel METEOR for an expedition along the west coast of Africa, led by the GEOMAR Helmholtz Centre for Ocean Research Kiel. The expedition focuses on two poorly
Forecasting earthquakes presents a serious challenge on land, but in the oceans that cover around 70% of Earth's surface it is all but impossible. However, the vast network of undersea cables that crisscross the world's seas could soon change this. As well as transmitting data
