Can hook-bending be let off the hook? Bending/unbending of pliant tools by cockatoos
The spontaneous crafting of hook-tools from bendable material to lift a basket out of a vertical tube in corvids has widely been used as one of the prime examples of animal tool innovation. However, it was recently suggested that the animals' solution was hardly innovative but strongly influenced by predispositions from habitual tool use and nest building. We tested Goffin's cockatoo, which is ...

متن کاملInterstrand crosslink repair: can XPF-ERCC1 be let off the hook?
The interstrand crosslink (ICL) presents a challenge to both the cell and the scientist. From a clinical standpoint, these lesions are particularly intriguing: ICL-inducing agents are powerful tools in cancer chemotherapy, and spontaneous ICLs have recently been linked with accelerated aging phenotypes. Nevertheless, the ICL repair process has proven difficult to elucidate. Here we discuss rece...
متن کاملOff the hook: what Olin might mean.
Background. Bacillus anthracis, the etiologic agent of inhalational anthrax, is a facultative intracellular pathogen. Despite appropriate antimicrobial therapy, the mortality from inhalational anthrax approaches 45%, underscoring the need for better adjuvant therapies. The variable latency between exposure and development of disease suggests an important role for the host’s innate immune respon...
متن کاملCorpus Analysis Tools for Computational Hook Discovery
Compared to studies with symbolic music data, advances in music description from audio have overwhelmingly focused on ground truth reconstruction and maximizing prediction accuracy, with only a small fraction of studies using audio description to gain insight into musical data. We present a strategy for the corpus analysis of audio data that is inspired by the FANTASTIC toolbox and optimized fo...
