New alternatives in photoprotection: Preparation and evaluation of lamellar silicate derivatives and their use as sunscreens

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The use of nanotechnology in sunscreens has increased, with various filters and organoclays tested for new intercalated formulations. As animal toxicity tests decrease, New Approach Methodologies are favoured. The S4 + OMC‐NC improved cell survival under SSL and showed antimutagenic properties, making it a promising candidate for safe photoprotection ...

Evidence for a Role of Extraintestinal Pathogenic Escherichia coli, Enterococcus faecalis and Streptococcus gallolyticus in the Aetiology of Exudative Cloacitis in the Critically Endangered Kākāpō (Strigops habroptilus)

open access: yesMolecular Ecology, EarlyView.
ABSTRACT The kākāpō is a critically endangered flightless parrot which suffers from exudative cloacitis, a debilitating disease resulting in inflammation of the vent margin or cloaca. Despite this disease emerging over 20 years ago, the cause of exudative cloacitis remains elusive.

Low‐Coverage Whole‐Genome Analysis of Population Structure, Bottlenecks, and Selection in Indiana Bats Before and After White‐Nose Syndrome

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Conservation successes for the endangered Indiana bat (Myotis sodalis) in the early 2000s were largely reversed by white‐nose syndrome (WNS), a novel fungal disease that emerged in North America in 2006. Impacts have been variable among Indiana bat colonies leading to uncertainty regarding the full impact of WNS on this species.
