Comparative architecture of the tessellated boxfish (Ostracioidea) carapace.

Tessellations (surface architectures of arrays of hard tiles) are common in natural and man-made designs. Boxfishes (Ostracioidea) are almost completely encased in a tessellated armor and have evolved a plethora of cross-sectional carapace shapes, yet whether the scutes constructing these exhibit comparable variation is unknown. Using high-resolution microCT and semi-automatic segmentation algorithms, we quantitatively examined thousands of scutes from 13 species of diverse body form.

Sex-dependent effects of ethanol withdrawal from a single- and repeated binge episode exposures on social anxiety-like behavior and neuropeptide gene expression in adolescent rats.

Ethanol withdrawal sensitivity is a risk factor for the development of alcohol use disorder. Heavy episodic drinking during adolescence often encompasses repeated periods of withdrawal. Adolescent intermittent ethanol exposure of laboratory rodents produces several neurobiological deficits that differ between sexes, but the sensitivity to withdrawal as a contributor to the observed sex differences is not clear.

Prelimbic cortex perineuronal net expression and social behavior: Impact of adolescent intermittent ethanol exposure.

Adolescent intermittent ethanol (AIE) exposure in rats leads to social deficits. Parvalbumin (PV) expressing fast-spiking interneurons in the prelimbic cortex (PrL) contribute to social behavior, and perineuronal nets (PNNs) within the PrL preferentially encompass and regulate PV interneurons. AIE exposure increases PNNs, but it is unknown if this upregulation contributes to AIE-induced social impairments.

AEDES ALBOPICTUS IN-HOUSE WINTER BREEDING IN GERMANY-A CASE STUDY.

In February 2024, a resident of Mannheim, Germany, collected aggressively attacking mosquitoes in her home and forwarded them to the "Mueckenatlas" citizen science recording scheme. The specimens turned out to be Aedes albopictus. Upon discussing the situation and consultation on the biology of the Asian tiger mosquito, the submitter found numerous developmental stages in the water of a flowerpot with an orchid in her living room.
