Distinct neuron types in the auditory organ are necessary for encoding different features of sound and relaying them to the brain. Researchers at Karolinska Institutet provide evidence of an early, neuronal activity-independent, emergence of the different subtypes of auditory neurons, prior to birth in mice. The findings have recently been published in Nature Communications.

The clinical outcome and severity of COVID-19 cannot be explained by a single factor like age, gender, or comorbidities. A new study from Karolinska Institutet in Sweden has identified potential determinants of COVID-19 severity at the cellular level using advanced systems biology analysis. The findings, published in the journal Cell Systems, offer insights into the metabolic tug-of-war in the human body and its association with disease severity.

For a drug to be effective and not harmful it needs to be administered at the right dosage. Certain enzymes in the body eliminate drugs, and the activity of these enzymes vary between individuals. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden have studied two enzymatic variants which eliminate drugs less efficiently and show that the these enzyme variants are inherited from Neandertals.
