AQUILA: A laboratory facility for the irradiation of astrochemical ice analogs by keV ions.

The detection of various molecular species, including complex organic molecules relevant to biochemical and geochemical processes, in astronomical settings, such as the interstellar medium or the outer solar system, has led to the increased need for a better understanding of the chemistry occurring in these cold regions of space. In this context, the chemistry of ices prepared and processed at cryogenic temperatures has proven to be of particular interest due to the fact that many interstellar molecules are believed to originate within the icy mantles adsorbed on nano- and micro-scale dust particles. The chemistry leading to the formation of such molecules may be initiated by ionizing radiation in the form of galactic cosmic rays or stellar winds, and thus, there has been an increased interest in commissioning experimental setups capable of simulating and better characterizing this solid-phase radiation astrochemistry.

Diffusion-Based Generation of Neural Activity from Disentangled Latent Codes.

Recent advances in recording technology have allowed neuroscientists to monitor activity from thousands of neurons simultaneously. Latent variable models are increasingly valuable for distilling these recordings into compact and interpretable representations. Here we propose a new approach to neural data analysis that leverages advances in conditional generative modeling to enable the unsupervised inference of disentangled behavioral variables from recorded neural activity.

Further records of social parasitic ants in Europe and review of the Bulgarian species.

Background: Social parasitic ants exploit the colonies of other ant species, either permanently or temporarily. The permanent parasites are amongst the rarest species of ants, although their hosts may be very common. Due to their rarity and often restricted distribution range, most of them are listed as vulnerable.

can promote development in honeybee gut: an underrated threat for bees?

The genus harbors opportunistic pathogenic species, among which is pathogenic for honeybees although little studied. Recently, virulent strains of colonizing the mite's mouth were found vectored into the honeybee body, leading to septicemia and death. also occurs as an opportunistic pathogen in the honeybee's gut with a low absolute abundance.
