Article Synopsis
- * This research marks the first discovery of kaolinite or halloysite on another planet, alongside findings of dehydrated minerals indicating possible intense alteration processes.
- * The rocks' formation likely resulted from intense water activity followed by heating and dehydration, possibly linked to impact events that dispersed the materials across the crater.
Article Synopsis
- The study investigates population divergence in silvereye birds (Zosterops lateralis) by analyzing genetic data from mainland and island subspecies in southeastern Queensland, Australia.
- It reveals that geographic isolation, particularly due to water barriers, plays a crucial role in driving divergence among island populations despite short distances.
- Findings indicate that while genetic diversity is similar between island and mainland populations, island populations exhibit lower inbreeding, suggesting a unique evolutionary path influenced by their isolated environments.
Contagious ovine digital dermatitis (CODD) causes a severe, infectious foot disease and lameness of sheep, is common within the UK and is now also emerging in other countries. As well as causing severe animal welfare issues, huge economic losses emerge from the disease due to weight loss/lack of weight gain, and veterinary treatments. CODD lesion progress is measured, with a scoring system from 1 (early lesions) to 5 (healed).

Doppler ultrasound was used to measure AOP of the brachial and superficial femoral arteries using straight and curved blood flow restriction cuffs in 21 males and 21 females. Vessel diameter and blood flow were evaluated as independent predictors of AOP.
