Economists and environmental scientists see the world differently—here's why that matters‎

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 of symptoms or learned triggers. Because they're looking at the problem differently, they'll resort to completely different treatments.

Draining wetlands produces substantial emissions in the Canadian Prairies‎

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 development.

Genetic analysis reveals an alternative explanation for the Jomon migration to Japan‎

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, suggests that an initial migration of a single lineage later split, giving rise to regional diversity. The findings are published in the journal Anthropological Science.

What it really means to love your job—and when that love can become a liability‎

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 commitment rather than an economic transaction.

Bushbabies reclassified as 'near threatened.' Scientists share how to protect these adorable primates‎

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 from the eerie, wailing noises they make at night.

Atrocities take place in democratic nations as well as autocratic ones—our database has logged them all‎

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 deaths of more than 1,300 people in the U.S., according to data tracking such incidents.

Researchers measure Puijo lichens and microbes for canopy nitrous oxide uptake‎

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 of Eastern Finland since the mid-1980s, led by Professor Emeritus Pertti Martikainen. When Martikainen retired in 2016, Professor of Microbial Biogeochemistry Jukka Pumpanen took over as the group's leader," says Academy Research Fellow Henri Siljanen from the Department of Environmental and Biological Sciences.

Sea level rise worries most Hawaiʻi residents, survey finds‎

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 financed.

Expedition to investigate coastal Kelvin waves and marine heat waves in the tropical Atlantic‎

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 understood phenomena: the Benguela upwelling system off the coasts of Angola and Namibia, which partly operates independently of the wind, and the recurring marine heat waves known as Benguela Niños, which have a significant impact on the local climate and cause flooding in Angola and Namibia.

How 1.5 million km of undersea internet cables can double up as an earthquake and tsunami warning system‎

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 around the planet, they can also monitor the tectonic movements that cause earthquakes and tsunamis.
