Volcanic CO tracks the incubation period of basaltic paroxysms.

The ordinarily benign activity of basaltic volcanoes is periodically interrupted by violent paroxysmal explosions ranging in size from Hawaiian to Plinian in the most extreme examples. These paroxysms often occur suddenly and with limited or no precursors, leaving their causal mechanisms still incompletely understood. Two such events took place in summer 2019 at Stromboli, a volcano otherwise known for its persistent mild open-vent activity, resulting in one fatality and damage to infrastructure.

Participation of communal cattle farmers in drought risk reduction in Southern Zimbabwe.

Communal cattle farming has remained the mainstay of many rural livelihoods in Zimbabwe and beyond. This was an enterprise that has stood the test of time, despite the increasing threats from drought shocks in the last two decades in Southern Africa. Prevalence of weather-related shocks was of concern, which had not galvanised communal farmers to actively engage in disaster risk reduction (DRR) initiatives in order to shield cattle from the negative effects of drought.

Ground deformation reveals the scale-invariant conduit dynamics driving explosive basaltic eruptions.

The mild activity of basaltic volcanoes is punctuated by violent explosive eruptions that occur without obvious precursors. Modelling the source processes of these sudden blasts is challenging. Here, we use two decades of ground deformation (tilt) records from Stromboli volcano to shed light, with unprecedented detail, on the short-term (minute-scale) conduit processes that drive such violent volcanic eruptions.

Phenotype and genotype of 87 patients with Mowat-Wilson syndrome and recommendations for care.

Purpose: Mowat-Wilson syndrome (MWS) is a rare intellectual disability/multiple congenital anomalies syndrome caused by heterozygous mutation of the ZEB2 gene. It is generally underestimated because its rarity and phenotypic variability sometimes make it difficult to recognize. Here, we aimed to better delineate the phenotype, natural history, and genotype-phenotype correlations of MWS.

Common PHOX2B poly-alanine contractions impair RET gene transcription, predisposing to Hirschsprung disease.

HSCR is a congenital disorder of the enteric nervous system, characterized by the absence of neurons along a variable length of the gut resulting from loss-of-function RET mutations. Congenital Central Hypoventilation Syndrome (CCHS) is a rare neurocristopathy characterized by impaired response to hypercapnia and hypoxemia caused by heterozygous mutations of the PHOX2B gene, mostly polyalanine (polyA) expansions but also missense, nonsense, and frameshift mutations, while polyA contractions are common in the population and believed neutral. HSCR associated CCHS can present in patients carrying PHOX2B mutations.
