Hidden Armor, New Species: Scientists Find a Chiton in Korea's Coastal Waters

South Korean researchers have identified a new chiton species, Acanthochitona feroxa, living under stones along the west and south coasts. Using mitochondrial DNA sequencing and COI markers, they showed it is genetically distinct from the similar Acanthochitona defilippii, revealing hidden biodiversity in a lineage dating back more than 80 million years and highlighting the power of genetics in modern species discovery.

Neanderthal Ghost Lineage Revealed: 50,000 Years of Complete Isolation

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.

Exploring the Impact of Lifetime Cannabis Use on Brain Function and Structure

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.
