BACKGROUND Sponges have long been known to be ecologically important members of the benthic fauna on coral reefs. Recently, it has been shown that sponges are also important contributors to the nitrogen biogeochemistry of coral reefs. The studies that have been done show that most sponges are net sources of dissolved inorganic nitrogen (DIN; NH4 (+) and NO3 (-)) and that nitrification, mediated...

Environmental cues transduced by an endocrine network converge on Caenorhabditis elegans nuclear receptor DAF-12 to mediate arrest at dauer diapause or continuous larval development. In adults, DAF-12 selects long-lived or short-lived modes. How these organismal choices are molecularly specified is unknown. Here we show that coregulator DIN-1 and DAF-12 physically and genetically interact to in...

Cryptography is the science of secure computation and communication. The scope of cryptosystems, nowadays, ranges from private-key encryption and authentication to more complex systems such as publickey encryption, electronic voting, secure multi-party computation on large data sets, etc. My specialization is in foundations of cryptography, a field that aims at designing cryptographic protocols...

We present new estimates of emissions of nitrous oxide (N2O) from rivers and estuaries, using the NEWS-DIN model. NEWS-DIN is a model of the global transport of dissolved inorganic nitrogen (DIN) by rivers to coastal waters (Dumont et al. forthcoming). It calculates DIN export rates as a function of watershed characteristics, including human influences. We used the calculated DIN export rates b...

DNA damage-inducible (din) genes in Bacillus subtilis are coordinately regulated and together compose a global regulatory network that has been termed the SOS-like or SOB regulon. To elucidate the mechanisms of SOB regulation, operator/promoter regions from three din loci (dinA, dinB, and dinC) of B. subtilis were cloned. Operon fusions constructed with these cloned din promoter regions rendere...

Clear-cutting is today the primary driver of largescale forest disturbance in boreal regions of Fennoscandia. Among the major environmental concerns of this practice for surface waters is the increased mobilization of nutrients, such as dissolved inorganic nitrogen (DIN) into streams. But while DIN loading to first-order streams following forest harvest has been previously described, the downst...
