Researchers from the University of Copenhagen have discovered an important phenomenon beneath the Arctic sea ice that was previously thought impossible. This phenomenon could have implications for the food chain and the carbon budget in the cold north. The shrinking sea ice in the Arctic Ocean is, overall, a disaster.

Archaeology A research team led by the University of Copenhagen has uncovered a remarkable Early Bronze Age ceremonial gathering place at Murayghat in Jordan. The discovery may shed new light on how ancient societies responded to social and environmental upheaval. How did ancient cultures react to severe crises and the breakdown of the established social order? The 5,500-year-old bronze age site of Murayghat in Jordan, excavated by archaeologists from the University of Copenhagen, may hold an answer.

Mesoamerica Christophe Helmke and Magnus Pharao Hansen have taken the first steps toward solving a major archaeological mystery surrounding the ancient Mexican city of Teotihuacan. Until now, the language of Teotihuacan has been unknown. More than two millennia ago, Teotihuacan was a thriving metropolis in central Mexico with up to 125,000 inhabitants.

PROTEOMICS Researchers from the University of Copenhagen have developed a groundbreaking method that allows for the analysis of thousands of proteins in heart tissue. This provides entirely new insights into the characteristics of heart diseases and could pave the way for more targeted treatments. Each year, cardiovascular diseases affect more than 65,000 Danes - conditions that claim the lives of one in five Danes.

Colorectal cancer Patients who have undergone surgery for colorectal cancer experience fewer serious complications and fewer readmissions when an AI tool supports treatment decisions, according to new research. The tool has the potential to save the healthcare system significant costs. Readmissions after surgery are demanding for patients and costly for society.

Discrimination How can we get the majority to recognise the discrimination experienced by minorities? A new study examines this question. The results show that both cold facts and warm stories can change perceptions - but in different ways. Researchers from the University of Copenhagen and Aarhus University have investigated how to raise awareness of discrimination.

Economics Although the average cash holdings (bank deposits) have increased in Denmark since 1996, almost half of the population still only has cash equivalent to one or two months of income. This is not just a temporary situation, according to research from the University of Copenhagen. Danes' low cash holdings are remarkably persistent.

Exercise Exercising in green surroundings improves mood, reduces stress levels, and improves heart rate compared to exercising in the city or indoors. This is shown by new research from the University of Copenhagen. The study provides new insights that can be used to improve public health. An hour of brisk walking in the forest, on the beach, or in a green park reduces stress hormones, improves mood, and makes exercise easier to enjoy.

Health New research from the University of Copenhagen shows that team sports are a highly effective and potentially life-extending form of exercise for patients with high blood pressure and COPD. Even after a relatively short training period involving team sports, participants showed significantly improved blood pressure.

Artificial intelligence does not necessarily help students learn more if it is only used to provide answers. However, research from the University of Copenhagen shows how aligning GenAI with learning theories and a human-centered perspective improves its educational impact. Artificial intelligence is here to stay.

Carbon Capture From waste to valuable resource: Chemists at the University of Copenhagen have developed a method to convert plastic waste into a climate solution for efficient and sustainable CO2 capture. This is killing two birds with one stone as they address two of the world's biggest challenges: plastic pollution and the climate crisis.

Greenland The Inuit arrived in Greenland several hundred years earlier than previously believed. This is revealed by a genetic mapping of sled dogs, conducted by researchers from institutions including the University of Copenhagen. For many of us, dogs are our best friends, but in Greenland, sled dogs have for centuries been more than just loyal companions: they are an indispensable workforce, contributing to hunting and pulling sleds across the country's icy terrain.

Politics With a few adjustments, the quality of online political debates can be significantly improved, according to new research. However, a better tone of debate does not necessarily change people's attitudes, the researchers behind the study point out. Online political debates are often characterised by sharp divisions, personal attacks and a low level of information.

ISOTOPES Medicines have a unique chemical fingerprint, according to a new study from the University of Copenhagen. Researchers say this knowledge can be used to trace counterfeit or stolen medicine. That's how many packages of illegal medicines EU agencies confiscated during an eight-month operation in 2024.

Microbiome An international research team led by scientists from the University of Copenhagen has discovered a common gut bacterium that lowers body weight and blood sugar while increasing bone density. The finding could pave the way for a new approach to preventing and treating cardiovascular disease, obesity, diabetes, and osteoporosis.

A new study challenges the notion that Americans fear ethnic and religious replacement. On the contrary, the majority want a more diverse United States. At a time marked by debate about identity, migration and national cohesion, a new study brings a surprising message: Most Americans want a more ethnically and religiously diverse society than the one they live in today.

Staphylococcus Goats, horses and cows carry a bacterium that could become an effective weapon against increased antibiotic resistance in society. New research from the University of Copenhagen shows that signaling molecules from this bacterium can treat infections caused by multi-resistant Staphylococcus bacteria in an animal model as effectively as antibiotics.

ANCIENT DNA A new study maps infectious diseases across millennia and offers new insight into how human-animal interactions permanently transformed our health landscape. A research team led by Eske Willerslev, professor at the University of Copenhagen and the University of Cambridge, has recovered ancient DNA from 214 known human pathogens in prehistoric humans from Eurasia.

Sea Levels Researchers from the University of Copenhagen have gained unique insight into the mechanisms behind the collapse of Antarctic ice shelves, which are crucial for sea level rise in the Northern Hemisphere. The discovery of old aerial photos has provided an unparalleled dataset that can improve predictions of sea level rise and how we should prioritise coastal protection and other forms of climate adaptation.
