Genetic analysis of a Neanderthal from Grotte Mandrin in southern France reveals a 'ghost lineage' named Thorin that lived about 50,000 years ago and remained completely isolated from other Neanderthal populations for ~50,000 years, suggesting Neanderthals were far more fragmented than previously thought even when neighboring groups coexisted.
A study using the UK Biobank suggests lifetime cannabis use is linked to changes in brain structure and function, particularly affecting white matter integrity and neuronal connectivity. However, genetic analysis indicates these changes may not be causally related to cannabis use, highlighting the need for further research. The study also notes sex-based differences in brain impact and emphasizes the importance of understanding cannabis's long-term effects as its global use increases.
