Three new species of the ditomyiid genus Calliceratomyia Lane, so far known only from the type-species from southeastern Brazil, are described from Mexico. The new species-Calliceratomyia papaveroi sp. n., Calliceratomyia pantelhomyia sp. n. and Calliceratomyia zayolli sp. n.-are described based on adult males collected with Malaise traps in the States of Oaxaca, Chiapas and Hidalgo, Mexico. The descriptions are illustrated and the diagnosis of the genus is revised.

Dog skull shape challenges assumptions of performance specialization from selective breeding.

Through selective breeding, humans have driven exceptional morphological diversity in domestic dogs, creating more than 200 recognized breeds developed for specialized functional tasks such as herding, protection, and hunting. Here, we use three-dimensional reconstructions of dog skulls to ask whether these function-oriented kennel-club groups reflect differences in morphology that correspond to those functions. We analyzed 117 canid skulls, representing 40 domestic dog breeds and 18 wild subspecies, using geometric morphometric techniques and -means clustering.

Cold atmospheric plasma (CAP) has emerged as a promising technology for neutralizing microbes, including multidrug-resistant strains. This study investigates CAP's potential as an alternative to traditional antimicrobial drugs for microbial inactivation. In the era of increasing antimicrobial resistance, there is a persistent need for alternative antimicrobial strategies.

Long-term effects of social play on neural and behavioral development remain unclear. We investigated whether just 1 h of juvenile social play could rescue the effects of play deprivation on stress-related behavior and markers of neural plasticity. Syrian hamsters were reared from postnatal days 21-43 in three conditions: peer isolation, peer isolation with daily social play sessions (dyadic play), or group-housed with littermates.

Capillary vibrating sharp-edge spray ionization (cVSSI) has been used to control the droplet charging of nebulized microdroplets and monitor effects on protein ion conformation makeup as determined by mass spectrometry (MS). Here it is observed that the application of voltage results in noticeable differences to the charge state distributions (CSDs) of ubiquitin ions. The data can be described most generally in three distinct voltage regions: Under low-voltage conditions (<+200 V, LV regime), low charge states (2+ to 4+ ions) dominate the mass spectra.
