Due to its completeness, the AL 288-1 (‘Lucy’) skeleton has long served as the archetypal
bipedal Australopithecus. However, there remains considerable debate about its limb …

We describe late Pliocene and early Pleistocene hominin fossils from Sterkfontein Caves (South
Africa), including two femoral specimens, as well as a partial tibia and a partial fibula. …

The 3.67-million-year-old StW 573 Australopithecus skeleton is important for the light it sheds
on the paleobiology of South African species of that genus, including, as discussed here, …

We present new Arecibo 21 cm line measurements of the temperatures of interstellar gas.
Our temperatures for the cold neutral medium are significantly lower than previous single-dish …

… The original data are published in a catalogue (Heiles 1966ci), available in limited …
with large radial motion will eventually collapse (Heiles 1966b), possibly forming stars …

A genetic algorithm (GA) coupled with density functional theory (DFT) calculations is used to
perform global optimisations for all compositions of 8-atom Au–Ag bimetallic clusters. The …

… This connection was pointed out by Ablowitz el aJ.in the … the well known Henon-Heiles
Hamiltonian. The Painleve property … that we have found for the Henon-Heiles system are remark- …

The hepatitis C virus (HCV) envelope proteins, E1 and E2, form noncovalent heterodimers
and are leading candidate antigens for a vaccine against HCV. Studies in mammalian cell …

… We reanalyze the interrelationships among Shane-Wirtanen galaxy counts, HI column
densities, and reddenings, and resolve many of the problems raised by Heiles. These problems …

The Arecibo Observatory (AO) is a multidisciplinary research and education facility that is
recognized worldwide as a leading facility in astronomy, planetary, and atmospheric and space …
