Turner, J. E., McLaughlin, M. A., Cordes, J. M., Lam, M. T., Shapiro-Albert, B. J., Stinebring, Dan R. ... NANOGrav Collaboration. (2021). The NANOGrav 12.5 year data set: monitoring interstellar scattering delays. Astrophysical Journal, 917(1), article 10.
From the abstract: "We extract interstellar scintillation parameters for pulsars observed by the NANOGrav radio pulsar timing program. ...For most pulsars for which scattering delays are measurable, we find that time-of-arrival uncertainties for a given epoch are larger than our scattering delay measurements, indicating that variable scattering delays are currently subdominant in our overall noise budget but are important for achieving precisions of tens of nanoseconds or less."
From the abstract: "Insects possess small brains but exhibit sophisticated behaviour, specifically their ability to learn to navigate within complex environments. To understand how they learn to navigate in a cluttered environment, we focused on learning and visual scanning behaviour in the Australian nocturnal bull ant, Myrmecia midas, which are exceptional visual navigators."
