Ornithologists tagged 27 juvenile birds to track the way they use updrafts of air heated by the sun to migrate over long distances.
The wings of black butterflies are inspiring the design of new solar-cell technology.

RADWANUL HASAN SIDDIQUE, KARLSRUHE INSTITUTE OF TECHNOLOGY / CALIFORNIA INSTITUTE OF TECHNOLOGYThe wings of the black butterfly, Pachliopta aristolochiae, are covered in microscopic scales that are particularly adept at harvesting sunlight over a wide spectral range. Scientists used these as a template for designing photovoltaic absorbers, showing that they have potential to increase the functionality of thin-film solar cells.
