Many researchers agree that shifting to a more plant-based diet is an important step towards reducing our impact on the climate. A new doctoral thesis from Karolinska Institutet describes the development and test of a new method of providing sustainable school lunches. The new lunch resulted in a 40 per cent reduction in climate impact with no increase in cost or decrease in consumption.

A large brain imaging study involving researchers at Karolinska Institutet demonstrates that same-sex sexual behaviour-related differences in the brain exist. Patterns in the brain that differentiate between men and women were less pronounced in non-heterosexual individuals, and some of the brain differences could be linked to a genetic predisposition for non-heterosexuality. The study is published in the scientific journal Human Brain Mapping.

Despite the importance of enzyme-substrate reactions in biology and medicine, there is a lack of general and unbiased tools for identifying substrate proteins for a given enzyme of interest. Scientists from Karolinska Institutet have now developed a new proteomics method called “System-wide Identification and prioritization of Enzyme Substrates by Thermal Analysis” (SIESTA). Their study is published in Nature Communications.

People with cardiometabolic risk factors such as high blood pressure, obesity and diabetes have an increased risk of life-threatening COVID-19 requiring treatment with invasive ventilation in the intensive care unit. The risk factors are more important in younger people, but there are also clear links between severe COVID-19 and other diseases such as asthma and chronic inflammatory diseases. The researchers believe the findings may be important for future vaccinations in younger age groups.

Almost one in five people lacks the protein α-actinin-3 in their muscle fibre. Researchers at Karolinska Institutet now show that more of the skeletal muscle of these individuals comprises slow-twitch muscle fibres, which are more durable and energy-efficient and provide better tolerance to low temperatures than fast-twitch muscle fibres. The results are published in The American Journal of Human Genetics.

Researchers at Karolinska Institutet explain that the neurotrophin brain-derived neurotrophic factor (BDNF) binds to the receptor tropomyosin receptor kinase B (trkB) present on the surface of many neurons, triggering signaling pathways critical to the maturation and growth of neurons during development. In their latest article however, they show that BDNF-trkB signaling also plays a significant role in the functioning of the adult brain.

Last year, researchers at Karolinska Institutet and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany showed that a major genetic risk factor for severe COVID-19 is inherited from Neandertals. Now the same researchers show, in a study published in PNAS, that Neandertals also contributed a protective variant. Half of all people outside Africa carry a Neandertal gene variant that reduces the risk of needing intensive care for COVID-19 by 20 percent.

The pandemic has meant that courses and programmes have only had a short time to transition to distance teaching – something which has required major involvement from teachers, students and educational administrators.
