Color terms and color concepts [PDF]
Journal of Experimental Child Psychology, 2006 In their lead articles, both Kowalski and Zimiles (2006) and O'Hanlon and Roberson (2006) declare a general relation between color term knowledge and the ability to conceptually represent color. Kowalski and Zimiles, in particular, argue for a priority for the conceptual representation in color term acquisition.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Color categories and color appearance [PDF]
Cognition, 2012 We examined categorical effects in color appearance in two tasks, which in part differed in the extent to which color naming was explicitly required for the response. In one, we measured the effects of color differences on perceptual grouping for hues that spanned the blue-green boundary, to test whether chromatic differences across the boundary were ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Background-matching, disruptive coloration and the evolution of cryptic coloration
, 2005 Cryptic prey coloration typically bears a resemblance to the habitat the prey uses. It has been suggested that coloration which visually matches a random sample of the background maximizes background matching.

Leucism occurrence frequency in an island population of tayra (Eira barbara), in Roraima, Brazil: A comparative analysis with camera trap records [PDF]
Acta AmazonicaCarnivores have a wide variation of color patterns that serve both ecological and physiological functions. However, genetic mutations can lead to the appearance of unusual color patterns, which can directly influence the survival of individuals.

Journal of Agricultural Sciences, 2020 This study was designed to determine the ideal dosages of marigold (Tagetes erecta) and synthetic carotenoid in blue streak hap (Labidochromis caeruleus) and pindani (Pseudotropheus socolofi) fry (Cichlidae), and to compare effects on the growth and skin

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
