I am a scientist, obsessed with birds, nature, mitochondria and telomeres.
New research provides evidence that mercury and PFAS can influence mitochondrial function in free-living seabirds, highlighting bioenergetics as a sensitive mechanistic link between pollution exposure and organismal health. 🔗 Press release: www.bi.mpg.de/news/2026-01-hau
Marine pollutants disrupt cellular energy production in seabirds
A new study showed that presence of mercury was linked to inefficient fuel use during energy production in wild birds’ cells, while certain per- and polyfluoroalkyl substances (PFAS) may prevent prote...

Please repost: 🚨Field assistant position 🐧 We offer a 14-months field assistant position through the French Polar Institute to work on king penguin ecophysiology and behavioral ecology. Requirements: EU citizen < 30yo having experience with harsh fieldwork & wild bird/mammal handling/sampling.
Excited to share our new paper! 🎉 we explored foraging behavior, contaminant exposure ( #Hg & #PFAS), and mitochondrial bioenergetics, revealing how #pollution can affect cellular energy in an apex marine predator @stefi-casagrande.bsky.social #mitochondria pubs.acs.org/doi/full/10....
Pollutant Exposure Shapes Mitochondrial Bioenergetics in a Wild Seabird
Laboratory studies show that mercury (Hg) and per- and polyfluoroalkyl substances (PFAS) can impair mitochondrial bioenergetics, which is a vital process for cellular energy production. However, their...

New documentary on our work with the enchanting #Scopoli’s #shearwater in #Linosa— a story of winds, wild journeys and also #mitochondria. 🐦🌊 So glad to have worked on this with #GiacomoDell’Omo and an amazing team #ValeriaVizioli #JürgenHansen #ArteTV #prospecttv www.arte.tv/de/videos/11...
