Scientists have discovered a new, more southern population of the rare monito del monte marsupial in Patagonia, extending its known range by about 100 km. This finding suggests there may be other hidden populations of this ancient, evolutionarily unique animal, which is crucial for planning its conservation in the face of climate change.

A new study shows that white-tailed eagle populations in northern Europe, after recovering from near-extinction, are now being limited by their own growing numbers and by warming sea temperatures. This means that even successful conservation stories face new challenges, as climate change and competition for resources start to curb future population growth.

Researchers used a new genetic technique to silence specific chromosomes and found that natural genetic variations, not just having an extra chromosome, can control whether a gene linked to Down syndrome is turned on or off. This uncovers a hidden layer of complexity in genetic disorders, showing that an individual’s unique DNA sequence can significantly influence how extra genes behave.
