A recent study published in the journal Nature reveals that the Neolithic era in North Africa was shaped by a complex interplay of cultures between African hunter-gatherers, European farmers, and Near Eastern pastoralists. The study, which analyzed genomic data from Neolithic human remains in the Maghreb region, challenges previous theories about the origins of agriculture and livestock in North Africa. The findings suggest that the Neolithic Revolution in this region was the result of a multifaceted process involving cultural exchanges, genetic mixing, and the adoption of new techniques from immigrant groups. This research sheds new light on the diverse origins and shared knowledge of ancient populations in North Africa over 7,000 years ago.

A new study published in The Lancet found that centenarians may possess a distinct genetic composition in their immune cells that makes them less prone to disease as they grow older. The research revealed that the study participants' immune cell profiles did not appear to have undergone the typical transformations associated with aging. The study team also identified the heightened expression of one particular gene associated with fighting off DNA damage as a factor in longevity. The findings may help inform developments in future therapies to allow patients to enjoy many more years to come.
