Diffuse degassing of carbon dioxide on the NW sector of Colli Albani volcanic complex (Rome, Italy)

Systematic CO2 soil flux surveys at Cava dei Selci on the Colli Albani volcano (28 seasonal surveys since the year 2000) have shown a significant variation of diffuse CO2 release, with a marked decrease, from 25 to 4 tonnes/day, from May 2000 to August 2004, followed by a new increase. Over the same period, CO2 flux halved at S. Maria delle Mole (16.8 tonnes/day in 2000 and 8.3 tonnes/day in 2006). Also the quantity of CO2 dissolved in the deep waters of the Albano crater lake decreased by one order of magnitude in the period 1997-2006. The high CO2 flux values in 2000 could represent the “tail” of a strong degassing episode recorded at Colli Albani in 1995 and related to local earthquakes. The following decrease of CO2 flux could reflect a permeability decrease caused by hydrothermal calcite precipitation favored by PCO2 reduction in the deep sourc

Repurposing an osteoporosis drug for β cell regeneration in diabetic patients.

Replenishing the lost or dysfunctional insulin-producing β cell mass in diabetic patients could slow down or reverse disease progression. Kondegowda et al. (2015) now show that osteoprotegerin and denosumab, inhibitors of the receptor activator of the NF-κB Ligand (RANKL) pathway and osteoclast activation, stimulate human β cell proliferation and therefore possess therapeutic potential
