Wavelet analysis of the ionospheric response at mid-latitudes during the April 200 storm using magnetograms and vTEC from GPS [PDF]
, 2013 In this work we pursue the idea of computing a parameter that allows us to estimate the local ionospheric response to a geospheric event that triggers an ionospheric storm. For that, wavelet technique has been chosen because of its ability to analyze non-

Record phenological responses to climate change in three sympatric penguin species
Journal of Animal Ecology, EarlyView.This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.One coordinate pnictide (Pn3− = P, As, and Sb) salts of TiIV and ZrIV were prepared using PnH2− as pnictogen atom transfer from suitable TiII and ZrIV complexes through H2 extrusion. This strategy allows access to unprecedented 3d and 4d terminal stibides, alongside phosphide and arsenide analogues, enabling systematic comparisons across the Pn group ...

Grassland Science, EarlyView.Abstract High Andean grasslands are vulnerable to changes in their nutritional quality and carbon sequestration capacity, especially in grazing systems. This study evaluated soil quality and native grasses by measuring carbon, physicochemical parameters, and the nutritional quality of predominant species in the wet Puna of Junín, Peru.
