    Travel fosters tool use in wild chimpanzees

    Thibaud Gruber et al.
    Travel has a major influence on tool use in wild chimpanzees, suggesting that tool use reduced travel costs during hominid evolution.

    Decoding the neural mechanisms of human tool use

    Jason P Gallivan et al.
    Imaging experiments reveal that some brain regions do not distinguish between actions performed using tools and those performed using the hands, while others represent these two types of action separately.

    Stone Tool Use: Monkeys overharvest shellfish

    George H Perry, Brian F Codding
    The use of stone tools by macaques in Thailand has reduced the size and population density of coastal shellfish; previously it was thought that tool-assisted overharvesting effects resulted uniquely from human activity.

  1. Research: Decoupling of the minority PhD talent pool and assistant professor hiring in medical school basic science departments in the US

    Kenneth D Gibbs Jr et al.
    A systems-level analysis of the biomedical workforce in the US shows that current strategies to enhance faculty diversity are unlikely to have a significant impact, and that there is a need to increase the number of PhDs from underrepresented minority backgrounds who move on to postdoctoral positions.

    A user-friendly, open-source tool to project impact and cost of diagnostic tests for tuberculosis

    David W Dowdy et al.
    A freely available computer program that takes into account specific local conditions enables users to predict the impact of adopting different diagnostic strategies on the spread of tuberculosis in their region.

    Group-specific archaeological signatures of stone tool use in wild macaques

    Lydia V Luncz et al.
    Tool behaviour of long-tailed macaques leaves archaeological signatures that differ between populations despite similar ecological conditions, highlighting the potential for diversity in material culture.

  2. Point of View: Correcting the bias against interdisciplinary research

    Ehud Shapiro
    When making decisions about funding and jobs the scientific community should recognise that most of the tools used to evaluate scientific excellence are biased in favour of established disciplines and against interdisciplinary research.

    Resource depletion through primate stone technology

    Lydia V Luncz et al.
    Technology-driven overharvesting of marine prey influences tool selection pattern in long tailed macaques, posing a serious threat to their behavioural traditions.
  3. Point of View: A fair deal for PhD students and postdocs

    Henry R Bourne
    The relentless expansion that threatens the sustainability of biomedical research in the US takes a heavy toll on young researchers.
