TL;DR: Transgenic mice that express high levels of human mutant APP support a primary role for APP/Aβ in the genesis of AD and could provide a preclinical model for testing therapeutic drugs.

TL;DR: In this paper, optical and ultraviolet spectra of the binary neutron star merger GW170817 were obtained nightly between 1.5 and 9.5 days post-merger, using the SOAR and Magellan telescopes.
Journal ArticleDOI
The whole earth telescope - A new astronomical instrument
TL;DR: In this article, a multimirror ground-based telescope for time-series photometry of rapid variable stars, designed to minimize or eliminate gaps in the brightness record caused by the rotation of the earth, is described.
Journal ArticleDOI

TL;DR: In this article, the power spectrum of a pulsating prewhite dwarf star (DPV) PG 1159 - 035 was resolved into 125 individual frequencies; 101 of them were identified with specific quantized pulsation modes, and the rest were completely consistent with such modal assignment.
