Shedding a light on the composition, toxicity and potential therapeutic strategies of internationally relevant ophidotoxins [PDF]
openAmong the four-thousand species of snakes currently known to taxonomists, around a fifth of them developed a peculiar hunting tactic based on injecting a toxic cocktail of compounds, generally referred to as “venom”, inside of their prey. This deadly

A neuro‐behavioural model of neophobia
Biological Reviews, EarlyView.ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

Loss, persistence and reversal of phenotypic traits
Biological Reviews, EarlyView.ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Chemistry – A European Journal, EarlyView.Nucleotide‐detected solid‐state NMR has been applied to probe nucleotide conformations and dynamics during ATP hydrolysis using the dimeric P‐loop ATPase SmsC as a model protein. The different stages of ATP hydrolysis have been mimicked by ATP analogues for which different degrees of conformational heterogeneity have been observed. ABSTRACT Solid‐state
