New dates from Sangiran suggest early humans arrived between 1.3-1.5 million years ago, nearly 300,000 years after previous estimates, with implications for understanding human migration and settlement in Asia.
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.
Researchers found that people tend to move to counties with similar political preferences, creating a 'hollowing out' of the political center. This phenomenon suggests that politically extreme counties can act as magnets for migration, further widening the political divide.
Researchers at the University of Arizona found that changes in rainfall patterns over the past 40 years have been insignificant in most places, with only some local areas showing significant changes. This suggests that scale matters and that climate change may not be the primary driver of migration from Central America.
Researchers Karen Culcasi and Cynthia Gorman examine how international laws formed after WWI contributed to today's hostile climate for refugees. They found that the creation of new countries, nationalism, and the establishment of international governance entities like the League of Nations shaped refugee law.
The study reveals that anatomically modern humans (Homo sapiens sapiens) first appeared in a southern African homeland and thrived there for 70,000 years. The researchers used mitochondrial DNA to reconstruct the earliest human population history, suggesting that climate changes triggered early migrations.
A team of researchers, led by Sean Ryan, documents the invasive history of the small cabbage white butterfly, which they attribute to human activities such as trade and migration. The study uses DNA analysis from over 3,000 submitted butterflies to reveal the butterfly's spread across Europe, Asia, Siberia, North America, and New Zealand.
Researchers are studying how environmental changes lead to migration and how migrants impact landscapes both at their destinations and origins. Climate change, deforestation, and socioeconomic inequalities are key drivers of this complex relationship, according to Claudia Radel, a geographer and migration researcher.
New discoveries at Cooper's Ferry site suggest humans occupied western Idaho by nearly 16,500 years ago. The findings support a Pacific coastal migration route and contradict the traditional 'ice-free corridor' hypothesis.
A study published in PLOS ONE found that nearly 30% of migrants through Mexico to the US experience physical, psychological, or sexual violence. Women and trans migrants are disproportionately affected by these incidents.
A radio-tracking study by University of Guelph biologists found that wind and temperature are more important influences than precipitation on daytime insect migration. The study revealed that insects can fly faster as it warms up, but flight is impeded when it gets too hot.
Researchers used sophisticated modelling to determine the likely routes travelled by Aboriginal people tens of thousands of years ago and the sizes of groups required for survival. The simulations indicate that at least 1300 people arrived in a single migration event or smaller waves, averaging 130 people every 70 years over 700 years.

A new study in the Serengeti-Mara ecosystem highlights how human activity near protected areas affects wildlife and ecosystem function. The results show that human pressure has caused wildlife to migrate to the core of the park, resulting in changes to fire regimes, grazing patterns, and increased vulnerability to droughts.
A global team predicts that by 2050, 49% of the world's population will live in areas where Aedes aegypti and Aedes albopictus mosquitoes are established. Climate change and human migration patterns drive the spread of these disease-carrying insects.
A study by National Research University Higher School of Economics found that educated migrants contribute to the convergence of wages across Russian regions. Migrants with secondary or vocational education levels have a significant impact on increasing regional wages, while higher-education migrants have little effect.
Research estimates that approximately 1.2% of the global population migrates every five years, resulting in up to 87 million people moving each year. Notably, around one-quarter of all migrations involve return journeys to individuals' countries of birth.
Researchers have developed a new statistical method to estimate migration flows between countries, revealing higher rates of migration and return migration. The pseudo-Bayes approach provides more accurate estimates than previous methods, with rates fluctuating between 1.1 and 1.3 percent of global population from 1990 to 2015.

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.
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.
Researchers urge governments to share more information about migration to track people moving between countries. Governments need to prioritize sharing data, training programs, and modeling to make better public policy decisions.
Researchers use diffusion equation and geographical data to simulate prehistoric human migration into England, Scotland, and Wales. The method accurately predicts points of contact between migratory paths, providing insights into early human dynamics.

The research found that greater enforcement raised costs and risks for migrants, causing them to stay longer in the US.
Researchers at the University of California, Riverside, found that corn grown in home and community gardens in Southern California has higher genetic diversity than commercial seeds. This discovery highlights the importance of preserving genetic resources through diverse farming practices.
The study found that local governance institutions and attitudes contribute to frontier-specific effects, including lower levels of law and order and public goods provision. Frontier settlers have developed a strong sense of autonomy, supporting right-wing parties and politicians who prioritize populist and patriotic statements.
A new study suggests that traditional assessment methods overestimate the vulnerability of salt marshes to sea-level rise. Salt marshes can generally survive higher rates of sea-level rise than predicted by current models, thanks to their ability to grow vertically and migrate landward.
A University of Warwick study suggests that EU policy must change to address the migrant crisis. Researchers propose four new measures: replacing deterrent border control with interventions addressing migratory causes, revising migration categories to reflect diverse reasons for migration, opening safe and legal routes, and improving r...
Research found that species with diverse migration patterns are less likely to decline, while those funneling into smaller areas are more vulnerable. Partial migrants, like Blackbirds and Robins, showed greater resilience to human impacts.
A study by the University of Exeter has found that the children of migrants tend to think and reason like the wider UK population. This shift occurs despite retaining cultural similarities with their parents. The research suggests that communities can integrate over a single generation, contrary to common assumptions.
