ENGINEERING Designing and constructing mechanical systems to operate at a microscale are challenging tasks. Yet, organisms such as fruit flies perform many of the desired movements and functions of a microscale robot within a compact body. Kenichi Iwasaki, Charles Neuhauser et al. developed a platform for harnessing the visual and olfactory systems of fruit flies to guide the flies in specific tasks.

Significance Migration of scientists contributes to circulation of ideas and innovation. While this is the case for both migration within a country (internal) and across countries (international), most research has focused only on international migration, due to lack of data. We generated a global database of migration of researchers that includes internal mobility and enables us to study the interrelationships between internal and international migration, and how they affect each other.
