An individual human can maintain stable social relationships with about 150 people. This is known as ‘Dunbar’s number’. A new study indicates that a cognitive limit on human group sizes cannot be derived in this manner.
Another piece of the puzzle has fallen into place regarding the Viking town of Birka. Parts of the town were encircled by a moat, suggesting that Birka was fortified against hostile attacks. This is one of the findings of a new archaeological research study at Stockholm University.
"We have enormous sustainability challenges ahead of us. In order to handle these challenges, we need collaboration. Meet Albert Norström and Marie Löf at the Baltic Sea Centre, in a film about the study.
Over half of our drugs impact proteins found on the cell membrane. These include the membrane proteins that regulate uptake of sugar by cells. Wallenberg Scholar David Drew is breaking new ground by adding to our understanding of the structure and function of transport proteins.
An individual human can maintain stable social relationships with about 150 people. This is the proposition known as ‘Dunbar’s number’ – that the architecture of the human brain sets an upper limit on our social lives. A new study from Stockholm University indicates that a cognitive limit on human group sizes cannot be derived in this manner.
