Early maternal loss leads to short- but not long-term effects on diurnal cortisol slopes in wild chimpanzees

Unveiling the population of orphan Gamma Ray Bursts [PDF]

open access: yes, 2015
Gamma Ray Bursts are detectable in the gamma-ray band if their jets are oriented towards the observer. However, for each GRB with a typical theta_jet, there should be ~2/theta_jet^2 bursts whose emission cone is oriented elsewhere in space.
