Although transposable elements (TEs) are known to be potent sources of mutation, their contribution to the generation of recent adaptive changes has never been systematically assessed. In this work, we conduct a genome-wide screen for adaptive TE insertions in Drosophila melanogaster that have taken place during or after the spread of this species out of Africa. We determine population frequenc...

The function of the human Tes protein, which has extensive similarity to zyxin in both sequence and domain organization, is currently unknown. We now show that Tes is a component of focal adhesions that, when expressed, negatively regulates proliferation of T47D breast carcinoma cells. Coimmunoprecipitations demonstrate that in vivo Tes is complexed with actin, Mena, and vasodilator-stimulated ...

Remarkable progress has occurred in many branches of biology and health sciences during the last few decades. Trace element (TE) research has definitely shared in this explosion of scientific knowledge. Due to the improvements in analytical technology, the discovery of TEs in organism was realized. The developments of TE research have been promoted by the demand of public health (e.g. deficienc...

[1] The Tropospheric Emission Spectrometer (TES) is an infrared instrument that was launched on board NASA’s Aura satellite in 2004. TES is the first instrument to provide vertical information on tropospheric ozone while simultaneously measuring CO on a global basis. Before they may be used for scientific study, TES profiles must first be validated to determine if there are any systematic biase...

Transposable elements (TEs) and repetitive sequences make up over 35% of the rice (Oryza sativa) genome. The host regulates the activity of different TEs by different epigenetic mechanisms, including DNA methylation, histone H3K9 methylation, and histone H3K4 demethylation. TEs can also affect the expression of host genes. For example, miniature inverted repeat TEs (MITEs), dispersed high copy-...

The chemical and structural organization of the plant cell wall was examined in Zinnia elegans tracheary elements (TEs), which specialize by developing prominent secondary wall thickenings underlying the primary wall during xylogenesis in vitro. Three imaging platforms were used in conjunction with chemical extraction of wall components to investigate the composition and structure of single Zin...

[1] Constraints on the mineralogical composition of low-albedo, low-sulfur sands at Meridiani Planum are determined from Mars Exploration Rover (MER) Opportunity Miniature Thermal Emission Spectrometer (Mini-TES), Mössbauer, and Alpha Proton X–Ray Spectrometer measurements. Results of this work show that the sand is olivine basaltic in composition, with minor amounts of sulfate and a high-silic...

Transposable elements (TEs) are powerful facilitators of genome evolution, and hence of phenotypic diversity as they can cause genetic changes of great magnitude and variety. TEs are ubiquitous and extremely ancient, and although harmful to some individuals, they can be very beneficial to lineages. TEs can build, sculpt, and reformat genomes by both active and passive means. Lineages with activ...

The 15-year development of the European interpretation of the Transition Edge Sensor (TES) microcalorimeter is described within this document. In essence, a TES microcalorimeter is a high-resolution cryogenic photon detector that converts temperature changes induced by incoming photons into changes in electrical resistance. Conceptually, the device consists of an absorber, a detector, heat sink...
