Algorithms can also learn without examples
In donut-shaped buildings, particle accelerators take super-detailed X-ray images. Yet those images are not good enough to learn how to drive on hydrogen for example. Mathematics PhD student Allard Hendriksen has developed an algorithm that improves the images without having to learn from data from…

Foraging skills may have made the essential difference in the evolution of our huge brain
Hunter-gatherers acquire their food through complex gender-specific foraging techniques for a relatively stable and diverse supply of energy. New research indicates that this specialisation by boys and girls starts at a very young age. Most likely, this enabled the human species to evolve much larger…
