TL;DR: Variance of hospital stays and costs calculated from these preliminary data suggests that 1,500 to 2,000 patients must be evaluated over at least a 1-year period to determine whether the CYP2D6 genetic variation significantly alters the duration of hospital stay and costs.

TL;DR: In this paper, the authors present an atlas of high-resolution M-dwarf spectra and compare the spectra to atmospheric models and demonstrate that in this spectroscopic range, the large amount of absorption features compensates for the intrinsic faintness of an M7 star.

TL;DR: Ground-based high-resolution spectroscopy detected excess absorption in the helium triplet during the transit of the Saturn-mass exoplanet WASP-69b, which is interpreted as the escape of part of the atmosphere trailing behind the planet in comet-like form.
