Next generation synthetic memory via intercepting recombinase function.

Here we present a technology to facilitate synthetic memory in a living system via repurposing Transcriptional Programming (i.e., our decision-making technology) parts, to regulate (intercept) recombinase function post-translation.

Engineering allosteric communication.

Protein allostery is a vitally important protein function that has proven to be a vexing problem to understand at the molecular level. Allosteric communication is a hallmark of many protein functions. However, despite more than four decades of study the details regarding allosteric communication in protein systems are still being developed.

Transcriptional programming using engineered systems of transcription factors and genetic architectures.

The control of gene expression is an important tool for metabolic engineering, the design of synthetic gene networks, and protein manufacturing. The most successful approaches to date are based on modulating mRNA synthesis via an inducible coupling to transcriptional effectors. Here we present a biological programming structure that leverages a system of engineered transcription factors and complementary genetic architectures.

Revision of the Neotropical water scavenger beetle genus García, 2001 (Coleoptera: Hydrophilidae: Acidocerinae).

The Neotropical water scavenger beetle genus Globulosis García, 2001 is revised. Originally described from a single male specimen from southeastern Venezuela, the genus has since been found in localities across the Guiana Shield region and beyond, including Colombia, Suriname, Guyana, and Brazil. The genus is redescribed.

Hexanchorus bifurcatus sp. nov., a new tepui riffle beetle (Coleoptera: Elmidae: Larainae) from Tafelberg, Suriname.

Here we present the first published record of a laraine elmid from Suriname, which represents a new species - Hexanchorus bifurcatus sp. nov. Specimens were collected from the summit of Tafelberg, a table mountain near the Wilhelmina Range of Suriname.

Review of the Lutrochidae (Coleoptera) of the Guianas and Lesser Antilles, with description of four new species.

The species of Lutrochidae from the Guianas, and the Lesser Antilles are reviewed, including the first reports of the family from Guyana, Suriname, and Grenada. Four species are described as new: Lutrochus funkae n. sp.

A new genus of egg case-carrying water scavenger beetle from the Guiana Shield (Coleoptera: Hydrophilidae: Acidocerinae).

Radicitus gen. n. is described to accommodate three new species of water scavenger beetles from the Guiana Shield region of South America: R.

Clade age and diversification rate variation explain disparity in species richness among water scavenger beetle (Hydrophilidae) lineages.

Explaining the disparity of species richness across the tree of life is one of the great challenges in evolutionary biology. Some lineages are exceptionally species rich, while others are relatively species poor. One explanation for heterogeneity among clade richness is that older clades are more species rich because they have had more time to accrue diversity than younger clades.

Ciimaerocyon gen. nov., a morphologically aberrant myrmecophilous genus of water scavenger beetle (Coleoptera: Hydrophilidae: Sphaeridiinae).

Anew hydrophilid genus Chimaerocyon gen. nov. containing two species, C.

A revision of the Lutrochidae (Coleoptera) of Venezuela, with description of six new species.

The species of Lutrochidae occurring in Venezuela are revised. The only previously recorded species, Lutrochus acuminatus Grouvelle, is redescribed and a lectotype is designated. Lutrochus vestitus Sharp, is recorded from Venezuela and French Guiana for the first time.

New species and new records of the hygropetric water beetle genus Oocyclus Sharp from South America (Coleoptera: Hydrophilidae).

Three new species of Oocyclus Sharp, 1882 are described from tropical South America: O. maluz sp. n.

Review of the Berosus Leach of Venezuela (Coleoptera, Hydrophilidae, Berosini) with description of fourteen new species.

The species of the water scavenger beetle genus Berosus Leach occurring in Venezuela are reviewed. Thirty-six species are recorded, including fifteen new species, fourteen of which are described here as new: Berosus araguasp. n.

Discovery of the water scavenger beetle genus Brownephilus Mouchamps in Turkey (Coleoptera, Hydrophilidae, Hydrophilini.

The recently described Hydrochara major İncekara, Mart, Polat, & Karaca, 2009 from Turkey is transferred to the genus Brownephilus Mouchamps. New records and habitat information are given for the species, as well as diagnostic features for separating it from the only other described member of the genus, Brownephilus levantinus Balfour-Browne. The discovery of Brownephilus in Turkey marks the first time the lineage has been found since its original description more than seventy years ago.
