In a new study, researchers at Uppsala University have clarified family relationships in four graves from a 5,500-year-old hunter-gatherer culture at Ajvide on Gotland. DNA analyses suggest that the people were well aware of family lineages and that relationships beyond the immediate family played an important role.
Generative AI can help fight misinformation but can also worsen it by creating convincing, hard‑to‑detect manipulations that spread quickly. A new study identifies seven roles AI can play in the information environment and examines their strengths, weaknesses, opportunities and risks.
With extreme weather events, fires and floods growing increasingly common, general warnings are no longer adequate. Researchers at Uppsala University, in collaboration with the World Meteorological Organization and others, now call for change – from mass mailings to personalised warnings that actually persuade people to act.
People affected by traumatic brain injury (TBI) have an increased risk of work disability that can recur even years after the injury, regardless of its severity. This has been shown in a new national registry study from Uppsala University in collaboration with Karolinska Institutet (KI) and is based on close to 100,000 people with a traumatic brain injury.
In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known. Some of the new genetic variants can be linked to an increased risk of gluten intolerance, haemorrhoids and cardiovascular diseases.
The number of patients diagnosed with cardiomyopathy has increased substantially over the past two decades. This is the finding of a new study from Uppsala University that mapped all cases of cardiomyopathy in Sweden. Despite identifying this increase, it is still unclear whether this is due to more people developing cardiomyopathy or to healthcare becoming better at diagnosing it.
Individuals with a birth weight of less than one kilogram have an increased risk of cerebral palsy, intellectual disabilities and attention deficit disorders. Nonetheless, they rate their quality of life as high as individuals with normal birth weight. This finding emerges from a new study of 201 adults who were born prematurely and followed from birth to the age of 26–29 in Sweden.
