Heart progenitors spontaneously regenerate cardiac muscle via a tight junction “honeycomb” in salamanders. Whether there are endogenous adult heart progenitors that can replenish damaged muscle cells remained controversial.

Vaccines based on inactivated SARS-CoV-2 virus are commonly used in resource-poor countries due to their low cost. New research from Karolinska Institutet shows that a booster shot of mRNA vaccine to individuals who have received two doses of inactivated vaccine offers the same level of protection against COVID-19 as three doses of mRNA vaccine. The findings are published in the journal Nature Communications.

A new study shows that the menstrual phase has effects on the microbiome. “This will be very important for planning future studies, both in basic science and for interventions aiming to improve the vaginal microbiome”, corresponding author Ina Schuppe Koistinen at the Department of Microbiology, Tumor and Cell biology at Karolinska Institutet, says.

Six predictors could help determine the amount of lithium needed to treat patients with bipolar disorder, according to a large study led by researchers at Karolinska Institutet in Sweden.

Researchers at Karolinska Institutet, Germany’s Technical University of Munich (TUM) and AstraZeneca, among others, have identified a unique therapeutic approach with the potential to restore heart function following a heart attack. The new findings rely on so-called human ventricular progenitor (HVP) cells to promote novel heart tissue and reduce scarring after injury. This pre-clinical study is published in the journal Nature Cell Biology.

A team of scientists including at Karolinska Institutet has used mini-kidneys simulating those of diabetic patients to further our understanding of the link between diabetes and COVID-19. The researchers found that diabetic mini-kidneys have a higher susceptibility to SARS-CoV-2 infection than non-diabetic mini-kidneys. The study, which is published in the journal Cell Metabolism, also identified genetic evidence for the essential role of the ACE2 receptor in COVID-19.

Researchers at Karolinska Institutet have studied how the screen habits of US children correlate with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect. The results are published in the journal Scientific Reports.

Screen time is often associated with poor health in young people, but it is more complicated than that, say researchers. We are affected, but differently and not just negatively. What we do on our phones – and what we do when we are not using them – also plays a role in our well-being.
