Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their...

The 2010 Deepwater Horizon oil release posed the challenges of two types of spill: a familiar spill characterized by buoyant oil, fouling and killing organisms at the sea surface and eventually grounding on and damaging sensitive shoreline habitats, and a novel deepwater spill involving many unknowns. The subsurface retention of...
We demonstrate a versatile and efficient setup to perform femtosecond stimulated Raman spectroscopy (FSRS). Technical innovations are implemented to achieve the wavelength tunability for both the picosecond narrowband Raman pump pulse and femtosecond broadband Raman probe pulse. Using a simplified one-grating scheme in a home-built second harmonic bandwidth compressor followed...
Adequate energy stores are essential for survival, and sophisticated neuroendocrine mechanisms evolved to stimulate foraging in response to nutrient deprivation. Food search behavior is usually investigated in young animals, and it is not known how aging alters this behavior. To address this question in Drosophila melanogaster, we compared the ability...
A nivel profesional los bibliotecarios han proclamado un responsabilidad ética que asegure acceso a la información a la población entera. Aún así existen muchas barreras para cumplir este cometido, entre ellos distintos niveles educativos y tecnológicos alrededor del planeta, costes a la hora de obtener información de investigación y concentración...
Climate change affects public land ecosystems and services throughout the American West and these effects
are projected to intensify. Even if greenhouse gas emissions are reduced, adaptation strategies for public lands
are needed to reduce anthropogenic stressors of terrestrial and aquatic ecosystems and to help native species
and ecosystems survive...
An experimentally based, quantitative understanding of the entrapment and function of small peptides within PEO brush layers does not currently exist. Earlier work provided a rationale for expecting that an ordered, compact peptide will enter the PEO phase more readily than a peptide of similar size that adopts a less...
