Birds face exceptionally high energy demands during their flight. One visible feature of some species is alternating between flapping and gliding, which should allow them to save energy. To date, there no empirical evidence an energetic benefit this. understand the physiology behind strategy, we equipped hand-raised Northern Bald Ibises ( Geronticus eremita ) with data loggers human-guided migr...

Full foil (50–260 nm) obtained from EDX derived Ag/Au weight ratio. Ultra-high-resolution SEM measurements, supported by STEM and RBS. Scientific evidence for paleness A special gilding material called Zwischgold has been frequently observ...

While progress in science sometimes results from the insight of a genius or from serendipity, more often it evolves from the toil of a vast number of investigators, each building upon another's contributions. Most of these investigators become casualties of progress; the stars of one era fade into oblivion in the light of the new knowledge in a new era. Only historians remember. In this autobio...
