Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing
an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed
the genome of M. osmundae, focusing on genes that may provide some insight into its
mode of pathogenicity and reproductive biology.
Mixia osmundae has the smallest plant pathogenic basidiomycete...

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...
Eucalypts are the world’s most widely planted hardwood trees. Their outstanding diversity, adaptability and growth have
made them a global renewable resource of fibre and energy. We sequenced and assembled >94% of the 640-megabase
genome of Eucalyptus grandis. Of 36,376 predicted protein-coding genes, 34% occur in tandem duplications, the largest...

Significant seabird mortality on the Oregon (OR) and Washington (WA) coast in 2009 has been attributed
to a massive bloom of the dinoflagellate Akashiwo sanguinea (K. Hirasaka) G. Hansen & Ø. Moestrup.
Initial, albeit limited, observations suggested this bloom began in WA and reached OR waters through
southward transport. Here,...

Stream-dwelling species in the U.S. southern Appalachian Mountains region are particularly vulnerable to climate change and acidification. The objectives of this study were to quantify the spatial extent of contemporary suitable habitat for acid- and thermally sensitive aquatic species and to forecast future habitat loss resulting from expected temperature increases...

Histone deacetylase (HDAC) inhibitors are undergoing clinical trials as anticancer agents, but some exhibit resistance mechanisms
linked to anti-apoptotic Bcl-2 functions, such as BH3-only protein silencing. HDAC inhibitors that reactivate BH3-only family
members might offer an improved therapeutic approach. We show here that a novel seleno-α-keto acid triggers global histone...

Sodium-ion batteries are emerging as a highly promising technology for large-scale energy
storage applications. However, it remains a significant challenge to develop an anode with
superior long-term cycling stability and high-rate capability. Here we demonstrate that the
Na⁺ intercalation pseudocapacitance in TiO₂/graphene nanocomposites enables high-rate
capability and long cycle life...

Emerging application areas such as air pollution in megacities, wind energy, urban security, and operation of unmanned aerial vehicles have intensified scientific and societal interest in mountain meteorology. To address scientific needs and help improve the prediction of mountain weather, the U.S. Department of Defense has funded a research effort—the...

There is a lack of consensus regarding the roles of sulfide saturation versus volatile degassing on the partitioning of Cu and Ag during differentiation and eruption of convergent margin magmas. Because of their oxidized character, volatile-rich magmas from the Eastern Manus Back-arc Basin (EMBB) only reach sulfide saturation following magnetite-driven...
