The aim of this work is to review current knowledge relating the established cancer hallmark, sustained cell proliferation
to the existence of chemicals present as low dose mixtures in the environment. Normal cell proliferation is under tight
control, i.e. cells respond to a signal to proliferate, and although most cells...

Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...
Two major types of glycerol dialkyl glycerol tetraethers (GDGTs) are commonly
used in paleoecological and paleoclimatological reconstructions: isoprenoidal and
branched GDGTs. In aquatic environments, it was originally assumed that isoprenoidal
GDGTs, especially crenarchaeol, derive mainly from aquatic Thaumarchaeota, whilst
branched GDGTs are an allochthonous input derived from soil Bacteria. Recently,...
Coastal wetlands are characterized by high biodiversity, which is one of the main criteria considered when establishing protection policies or when proposing adequate management actions. In this study, the crustacean and aquatic insect composition of the Emporda wetlands is described. These two faunal groups contribute highly to the total biodiversity...
The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...
What historical and political reality is reflected in the novels Gringo viejo and La frontera de cristal? What is revealed when the characters, plot, and setting of the novels are analyzed against research of the context of U.S.-Mexico relations? We begin to explore these questions by studying three periods crucial...
Extending rheological characterization methods to very small length scales is of interest. AC susceptometry using magnetic nanoparticle probes has been proposed for measurement of frequency-dependent rheological properties at the nanoscale. As this technique has been primarily used for ideally Newtonian fluids, this research aimed to extend this technique to viscoelastic...
