The Astrophysical Journal LettersRecent studies revealed viewing-angle-dependent color and spectral trends in brown dwarfs, as well as long-term photometric variability (∼100 hr). The origins of these trends are yet unexplained.

Sustainable Development, EarlyView.ABSTRACT As anthropogenic pressures increasingly impact marine ecosystems and the biodiversity they support, governance mechanisms for international biodiversity conservation have emerged. Seaweed habitats are important repositories for marine biodiversity, and they provide crucial ecosystem services that support both ocean and human health.

Configuring a Liquid State High‐Entropy Metal Alloy Electrocatalyst
Small, EarlyView.A liquid‐state high‐entropy metal alloy is developed to overcome key kinetic bottlenecks in ammonia electrosynthesis from nitrate. Atomically dispersed active sites and a dynamic hydrogen‐shuttling mechanism enable barrier‐free deoxygenation and hydrogenation. Guided by molecular dynamics, design of experiments, and density functional theory, the alloy

The potential for Earth-mass planet formation around brown dwarfs
, 2007 Recent observations point to the presence of structured dust grains in the discs surrounding young brown dwarfs, thus implying that the first stages of planet formation take place also in the sub-stellar regime.

An Informed and Systematic Method to Identify Variable Mid-L Dwarfs
The Astrophysical JournalMost brown dwarfs show some level of photometric or spectral variability. However, finding the most variable dwarfs more suited for a thorough variability monitoring campaign remained a challenge until a few years ago with the design of spectral indices ...

Unraveling Brown Dwarf Origins [PDF]
Science, 2004 Brown dwarfs, which occupy a fuzzy gap in mass between stars and planets, appear to be common both in the solar neighborhood and in star-forming regions. Their origin is a topic of significant current interest and debate. Some astronomers have suggested that brown dwarfs are stellar embryos, ejected from newborn multiple star systems. Others argue that

TAXON, EarlyView.Abstract The genus Indigofera in the Greater Cape Floristic Region (GCFR) comprises a diverse assortment of species. Almost 90% of the region's Indigofera species belong to the Cape Clade, while the remaining species are scattered among the other three globally distributed Indigofera clades.
