Large test suites are frequently used to evaluate software systems and to locate errors. Unfortunately, this process can generate a huge amount of data that is difficult to interpret manually. We have created a system, TARANTULA, that visually encodes test data to help find program errors. The system uses a principled color mapping to represent source lines in passed and failed tests. It also p...

The structure of the membranes of sarcoplasmic reticulum (SR), tubular (T) system, and sarcolemma has been studied by freeze fracture in leg muscles of the Tarantula spider. Two regions of the sarcoplasmic reticulum can be differentiated by the distribution of particles on the fracture faces: a junctional SR, at the dyads, and a longitudinal SR, elsewhere. The dyads are asymmetric junctions, th...

A fossil tarantula (Araneae: Mygalomorphae: Theraphosidae) is described from an exuvium in Tertiary (Miocene) Chiapas amber, Simojovel region, Chiapas State, Mexico. It is difficult to assign it further taxonomically, but it is the first mygalomorph recorded from Chiapas amber and only the second unequivocal record of a fossil theraphosid. With a carapace length of ca. 0.9 cm and an estimated l...

We present spectroscopic analysis of the luminous X-ray source Melnick 33Na (Mk 33Na, HSH95 16) in LMC 30 Doradus region (Tarantula Nebula), utilising new time-series VLT/UVES spectroscopy. confirm Mk as a double-lined O-type binary with mass ratio $q = 0.63 \pm 0.02$, $e 0.33 0.01$ and orbital period $18.3 0.1$ days, supporting favoured from observations obtained via Tarantula -- Revealed by X...
