Dunbar’s Number: Why the Theory That Humans Can Only Maintain 150 Friendships Has Withstood 30 Years of Scrutiny

Thirty years ago, Robin Dunbar theorized humans can maintain a friendship group of 150 people, with five intimate friendships. Despite many attempts to challenge the theory, Dunbar's Number has stood the test of time. Backed by neuroscience and statistics, Robin Dunbar explains why his theory still prevails.

COVID-19 pandemic likely to go in waves

A new mathematical model shows the current COVID-19 pandemic could decline during the summer months, but return in the fall, with a major resurgence next winter. The model takes into account the seasonal variations of other closely related respiratory coronaviruses. Based on other coronavirus data, the model reveals infections were ten times more common between December and April in the northern hemisphere than between July and September. Researchers emphasize this model only attempts to examine possible scenarios, as we are currently unsure how warmer temperatures will affect SARS-CoV-2.
