Record number celebrated equal opportunities with KI in the Pride parade

The late-summer sun shone down on Stockholm as Karolinska Institutet took part in this year’s Pride parade on 1 August. Together with KI President Annika Östman Wernerson, students, staff and alumni, the parade once again filled the streets with colour and enthusiasm during what was perhaps the most inclusive celebration of the year. The tragedy in Berlin cast a sombre shadow over the parade, serving as a reminder of why the event is so important.

New study

Somatic mutations linked to vascular damage in progeria

In the rare disease progeria, blood vessels deteriorate prematurely. A study shows how different cell types in the vascular wall undergo progressive changes and accumulate mutations over time.

New study

Digital visits may reduce inequalities in sexual healthcare

Young people with ADHD are more likely to visit youth clinics than their peers, while autistic individuals are less likely to do so, a new study shows. The results also suggest that digital healthcare consultations could help reduce these disparities.

Brain tau spreads differently in early- and late-onset Alzheimer's disease

The amount and distribution of the tau protein in the brain differs between early and late-onset Alzheimer's disease, a new study shows. The results also indicate that blood tests do not always reflect changes in the brain.

What vegan and vegetarian diets can and can’t tell us about eating disorders

Many people worry that following a vegetarian or vegan diet may signal an eating disorder. But a systematic review found no clear overall association, suggesting that the reasons behind dietary choices matter far more than the diet itself. Read the article in The Conversation.

A single dose of psilocybin eased depression symptoms for months

A single dose of the psychedelic substance psilocybin, found in so-called magic mushrooms, can provide rapid relief from recurrent depression, with the effects lasting for over three months, according to a new study. However, the researchers also caution that the results may have been influenced by the placebo effect. Read the article in The Conversation.
