Assessment of the exposure to <i>Phlebotomus perniciosus</i> and the presence of anti- <i>Leishmania infantum</i> antibodies in stray cats in an endemic region of Spain, and their potential correlation with environmental factors Open
Phlebotomus perniciosus is a major vector of Leishmania infantum in the Mediterranean. While the seroprevalence of leishmaniosis in Spanish dogs and cats has been studied, data on the exposure of cats to P. perniciosus bites under natural …

Formation and Stability of Salty Soil Seals in Mars‐Like Conditions. Implications for Methane Variability on Mars Open
Methane spikes observed in the Martian atmosphere require the abrupt release of large amounts of methane from the Martian subsurface. The mechanism for such release has not been identified. We tested whether gas traps can form under Mars‐l…
