  • In drawing tests, US children draw female scientists more today than in previous decades
    on March 20, 2018 at 4:00 am

    The participation of women in science has risen significantly in the United States since the 1960s. A new meta-analysis reviewed five decades of 'Draw a Scientist' tests to determine whether children's drawings have mirrored that change. The study found that US children and adolescents today draw female scientists more often than in earlier decades, but overall, female scientists are still depicted much less frequently than males in children's and youths' drawings.

  • US children now draw female scientists more than ever
    on March 20, 2018 at 4:00 am

  • Potential cognitive effects of targeted drugs in children may be reversible with therapy
    on March 20, 2018 at 4:00 am

    Young mice that received molecularly targeted therapies used to treat brain cancer in human patients sustained cognitive and behavioral deficits, but the deficits were largely reversible through environmental stimulation and physical exercise. The study suggests that pediatric brain cancer patients may experience similar side effects of molecularly targeted therapies, and may benefit from efforts to remediate any cognitive deficits. […]

  • Intensification of agriculture and social hierarchies evolve together, study finds
    on March 19, 2018 at 7:00 pm

    A long-standing debate in the field of cultural evolution has revolved around the question of how and why human societies become more hierarchical. Some theorize that material changes to a society's resources or subsistence strategies lead it to become more hierarchical; others believe that hierarchy is the cause rather than the result of these changes. Many see the answer as being somewhere on the spectrum between these two extremes. In order to test these theories, a group of researchers from […]

  • New life form answers question about evolution of cells
    on March 19, 2018 at 7:00 pm

    Bacteria and Archaea are two of the three domains of life. Both must have evolved from the putative last universal common ancestor (LUCA). One hypothesis is that this happened because the cell membrane in LUCA was an unstable mixture of lipids. Now, scientists from the University of Groningen and Wageningen University have created such a life form with a mixed membrane and discovered it is, in fact, stable, refuting this hypothesis. The results will be published in the journal Proceedings of […]
