Mobile Money and Economic Activity: Evidence from Kenya★.

This paper estimates the impact of access to mobile money services on local economic activity. The analysis combines data from the early expansion of the mobile agent network in Kenya with a local-level measure of economic performance proxied by the intensity of nighttime lights. Leveraging the variation in areas that gained access to mobile money services at different times and the high resolution of the data, the paper shows that access to mobile money services increased local economic activity and that these effects increased over time.

On the single and multiple associations of COVID-19 post-acute sequelae: 6-month prospective cohort study.

Medical research is progressing to clarify the full spectrum of sub-acute and long-term effects of the post-COVID-19 syndrome. However, most manuscripts published to date only analyze the effects of post-COVID-19 in patients discharged from hospital, which may induce significant bias. Here, we propose a pioneering study to analyze the single and multiple associations between post-COVID-19 characteristics with up to 6-months of follow-up in hospitalized and non-hospitalized COVID-19 patients.

Electrical properties of outer membrane extensions from MR-1.

MR-1 is a metal-reducing bacterium that is able to exchange electrons with solid-phase minerals outside the cell. These bacterial cells can produce outer membrane extensions (OMEs) that are tens of nanometers wide and several microns long. The capability of these OMEs to transport electrons is currently under investigation.

Surgical Management of Vulvar Melanoma: A Case Series.

Vulvar malignant melanoma is the second most common subtype of vulvar cancer, accounting for 5-10% of all vulvar cancers. The prognosis is still very poor, although some advances have been achieved in the last years. One of the most significant changes in its management has been the development of less invasive surgical techniques that diminish the risk of postoperative morbidity and long-lasting sequelae.
