(Phys.org) —Scientists have used selective breeding to create purple wings on the normally brown-winged butterfly Bicyclus anynana. Antonia Monteiro and her colleagues selected butterflies with wing scales that reflected ...
Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like traditional photographic film to record light for distances ...
