Eukaryotic ribosome biogenesis involves ~200 assembly
factors, but how these contribute to ribosome
maturation is poorly understood. Here, we
identify a network of factors on the nascent 60S subunit
that actively remodels preribosome structure. At its hub is
Rsa4, a direct substrate of the force-generating ATPase
Rea1. We show that...

The Antarctic contribution to sea level is a balance between ice loss along the margin and accumulation in the interior. Accumulation records for the past few decades are noisy and show inconsistent relationships with temperature. We investigate the relationship between accumulation and temperature for the past 31 ka using high-resolution records...

Recalcitrance to transformation makes genetic engineering of many valuable plants infeasible for practical use. Transitory host modification during transformation using transgenes offers a possible means of overcoming this obstacle. In prior work in our laboratory, the genes GA20ox7 and EBB1 were found to increase regeneration in vitro. In this project,...

Understanding continental crust formation and modification is a fundamental and longstanding geologic problem. Influx of mantle-derived basaltic magma and partial melting of the crust are two ways to drive crustal differentiation. This process results in a low density upper crust and denser, more refractory lower crust, creating significant and vastly...
