Local agricultural transition, crisis and migration in the Southern Andes - Nature In the Uspallata Valley, agriculture was adopted by local populations, as evidenced by genetic continuity from earlier hunter-gatherers to farmers; maize-dependent groups from the same regional p...

How did farming reach the Southern Andes? Through migration or cultural transmission? Our new paper in @nature.com combines ancient DNA, isotopes, archaeology & paleoclimate to reconstruct 2,000+ years of history in Uspallata, Mendoza.

Cow Tools!

We have lived alongside cows for nearly 10,000 years.
We breed them and exploit them

It is now, only now, that we have discovered THEY CAN USE TOOLS

Mutant CHCHD10 disrupts cytochrome c oxidation and activates mitochondrial retrograde signaling - EMBO Molecular Medicine Mutations in CHCHD10, a mitochondrial intermembrane space (IMS) protein implicated in proteostasis and cristae maintenance, cause mitochondrial disease. Knock-in mice modeling the human CHCHD10S59L va...

🟢 The Institut Pasteur goes green for Mitochondrial Disease Awareness Week! 🟢
These rare diseases affect 1 in 5,000 people. Mitochondria, the “powerhouses” of our cells, are also thought to play a role in Alzheimer's disease.

Mitochondria protect against an intracellular pathogen by restricting access to folate As major consumers of cellular metabolites, mitochondria are poised to compete with invading microbes for the nutrients that they need to grow. Whether cells exploit mitochondrial metabolism to protec...
