A new study suggests that summer monsoons from Asia and Africa reached the Middle East at least 125,000 years ago, providing suitable corridors for human migration. This finding corresponds with cyclical changes in Earth's orbit that brought increased summer precipitation, supporting animal and human migration into the region.
A new modeling approach can help researchers, policymakers and the public better understand how policy decisions will influence human migration as sea levels rise. The approach suggests that global policy decisions about greenhouse gas emissions and coastal policies will determine whether people need to migrate and where they may go.

A recent study published in PLOS ONE analyzed 194 native Latin American maize populations, revealing three distinct geographic groups of maize in Mexico and four groups in South America and the Caribbean. The findings suggest that genetic variation in maize populations may reflect human migration patterns and agricultural development.
A new study on genetic data of prehistoric human remains shows that only a few women participated in the migration from the Pontic-Caspian Steppe around 5,000 years ago, whereas men made up most of the migrants. This suggests that different social and cultural processes drove the two migrations.
Researchers used a model to simulate human migration in the Americas, finding that east-west migration was easier due to transferable knowledge. The study reveals how modularity of knowledge interacts with asymmetry during migration, with implications for understanding cancer metastasis and other biological systems.
Researchers discovered a population of previously unrecognized young neurons that migrate in the human brain during the first few months of life. These neurons contribute to inhibitory circuits, balancing excitatory activity, and are associated with the plasticity of the brain observed during postnatal development.
Researchers have discovered a previously unknown mass migration of inhibitory neurons into the brain's frontal cortex during the first few months after birth. This late-stage migration may play a role in establishing fundamentally human cognitive abilities.
A new study dispels the notion that millionaires are highly mobile, finding they are reluctant to move for tax benefits. The study reveals that only about 12,000 millionaires change states annually, and family responsibilities are a key factor limiting migration among top-income earners.
