Hypsarhythmia was originally spelled with one 'r' by Drs Frederick and Erna Gibbs when they coined the term in 1952.

Mapping the abundance of C in leaf-wax components in surface sediments recovered from the seafloor off northwest Africa (0–35°N) reveals a clear pattern of dC distribution, indicating systematic changes in the proportions of terrestrial C3 and C4 plant input. At 20°N latitude, we find that isotopically enriched products characteristic of C4 plants account for more than 50% of the terrigenous in...

The 2014 Ebola epidemic in West Africa is the largest ever recorded, and understanding the interrelated dynamics of surveillance and intervention is a key concern, both for this and future epidemics. Moreover, as transmissibility and mortality are believed to increase as symptoms progress, intervention strategies may depend on individual’s stage of infection. To examine these issues, we develop...

A case of West Nile virus (WNV) infection was reported in the Algarve region, Portugal, in the first week of September 2015. WNV is known to circulate in Portugal, with occasional reports in horses and birds (2004 to 2011) and very sporadically human cases (in 2004 and in 2010). Here we present the clinical and laboratory aspects related to the first human case of West Nile neuroinvasive diseas...

Entomological, veterinary, and human surveillance systems for West Nile virus (WNV) infection have been implemented in Italy since the first detection of the virus in 1998. These surveillance activities documented a progressive increase of WNV activity and spread in different regions and the emergence of new WNV lineages and strains. Italy is a paradigmatic example of the complex epidemiology o...

A West Nile virus (WNV) surveillance network including sentinel chickens was deployed in Thessaloniki county, Greece, from May to July 2011. For the first time in summer 2011, a chicken WNV isolate from 6 July was molecularly identified. The partial NS3 sequence was identical to that of the Nea Santa-Greece-2010 WNV lineage 2, detected in central Macedonia in 2010. This suggests that WNV is act...

To improve peoples’ living conditions, Western African countries need to considerably reinforce their electricity supply infrastructures. Retrofitting the existing installations and constructing new generation and transmission facilities require significant financial resources which are very difficult to attract due to the countries specific economic and political conditions. This paper discuss...
