Issues

Summary: Characterisation of taste buds in the developing bamboo shark, Chiloscyllium punctatum, reveals that taste papillae are functional, innervated units, allowing the shark to seek out food in utero, at birth or following hatching.

Summary: The spinocerebellar ataxia type 6 (SCA6) protein, α1ACT, causes polyglutamine length-dependent toxicity and aggregation in new Drosophila transgenic lines, opening the door for additional studies of this disease.

Summary: New SigD-regulated genes were identified in the plant growth-promoting rhizobacterium Bacillus amyloliquefaciens FZB42, which is closely related to the model organism B. subtilis.

Summary: Analysis of phosphopantetheinyl transferases and metabolic pathways for L-α-aminoadipic acid that are required for beta-lactam biosynthesis in the arthropod Folsomia candida.

Summary: The p68-related Drh1protein is essential for both growth and development of the ciliate Tetrahymena thermophila. It localizes to meiotic nuclei and is required for chromosome breakage of developing somatic chromosomes.

Summary: We show that the presence of a reflection peak in the NIR in some frogs can contribute to a temperature difference of up to 3.2°C, which extends the period they can go without rehydration by over an hour (22.7%).

Summary: Strigolactones signal through D14 to regulate shoot development by targeting SMXL6-clade proteins, but not BES1 or DELLA proteins, for degradation. BRC1 and PIN1 plausibly act downstream to regulate branching.

Summary: The findings here demonstrate that the signaling molecule retinoic acid (RA) plays an early role in determining how embryonic progenitor cells decide to differentiate into either mesodermal or neural tissues.

Summary: Using mouse embryonic stem cell cultures, we show BMP4 sufficiency to specify two cell fates and appropriate temporal patterning of the dorsal telencephalon, i.e. evidence for BMP4 as a dorsal telencephalic morphogen.

Summary: Cag1, a Tup1 homologue in Coprinopsis cinerea, is required for gill formation in fruiting body development and is highly expressed in the central region of gills.

Summary: The boundary layer laminarization of rainbow trout swimming in turbulent flows was confirmed. The results suggested an energy-efficient swimming strategy of this species in the turbulent flow environment.

Summary: In this study we used sound playback to test the importance of communication sounds of bats as contextual information for decision making for place preference during feeding.

Summary: Severely food-deprived snails cannot acquire conditioned taste aversion, because this conditioning is thought to be mitigated by a high content of a reward transmitter, dopamine, in these snails.

Summary: This work uncovers molecular determinants of Adgra2/Gpr124 and Reck trafficking to the plasma membrane where the partners meet to act as potent Wnt7-specific Wnt/β-catenin signaling co-activators required for brain vascularization.

Summary: We evaluate a metric for quantifying localization in microscopy images, termed the threshold overlap score, which is simple to calculate and interpret, generally applicable, and suitable for mixed localization patterns.
