A study found genetically similar lice on 1,000-year-old Peruvian mummies, challenging the idea that all diseases were transmitted from the Old World to the New World at the time of Columbus. The discovery sheds new light on human migration patterns and may help understand the origins of epidemic typhus.
Researchers found a 500,000-year-old human fossil in Turkey with evidence of Leptomeningitis tuberculosa, a form of brain tuberculosis. The discovery suggests that dark-skinned people migrating from low latitudes may be more vulnerable to the disease due to vitamin D deficiency.
Scientists investigate Hanford's vadose zone to understand contaminant migration and develop remediation solutions. They find complex pathways for nuclear waste travel, affecting composition and speed, impacting the environment and people downstream.
A study by Rafael Reuveny examines the impact of climate change on population migration and conflict. He advocates for a five-step approach to minimize climate change-induced migration and violent conflict in receiving areas.
Human migration out of Africa and into Asia occurred in at least four pulses, driven by climate and sea level changes. The initial migration was thwarted, but subsequent pulses took advantage of stable climates and sea levels to expand into eastern Asia, Australia, and Melanesia.
The special issue explores human migration, production systems, invasive species, and their effects on ecosystems, biodiversity, and conservation policy. Scientists propose an ecological knowledge system to facilitate access to new and existing sources of ecological information.
Scientists analyzed DNA and tooth shape in modern and ancient pigs to contradict longstanding ideas about Pacific colonist origins. The research suggests that ancient humans may have traveled between islands before reaching New Guinea and eventually landing on Hawaii and French Polynesia.
Researchers found that some viruses, like the human polyomavirus JCV, may be evolving at higher rates than previously assumed. The virus is traditionally used as a genetic marker for human migration and evolution, but its reliability has been called into question by this new study.
New evidence suggests Bering Strait flooded into Arctic Ocean 11,000 years ago, challenging traditional view of human migration from Asia to Americas. Sediment cores collected from Chukchi Sea reveal high resolution records of climate change and sea level rise.
A 6,000-year-old migration route of the pronghorn antelope in Yellowstone National Park is under threat from continued development and human disturbance. The study's findings highlight the need for immediate recognition and protection to safeguard this unique population.
Researchers suggest that productive kelp forests in the Pacific Rim may have facilitated human coastal migrations around 35,000 to 15,000 years ago. This theory is supported by findings of kelp forests near earliest coastal archaeological sites in the Americas.
Researchers used a popular internet game to study human travel patterns in the US, revealing statistical laws that can be applied to model infectious disease spread. The breakthrough model considers variables such as population density and transportation modes, offering improved predictions for future pandemics.
A three-year study by the University of Manchester found that people migrating from India to Britain are at greater risk of cardiovascular disease due to higher body mass, blood pressure, and cholesterol levels. The research highlights the importance of adopting a healthy lifestyle with a balanced diet and regular exercise.
A study suggests that the evolutionary history of tuberculosis is linked to historical patterns of human migration. The researchers found that the genetic signatures of over 300 strains of Mycobacterium tuberculosis reflect the dispersal and evolution of the pathogen according to human migration patterns, with a strong gender bias obse...
The Genographic Project is a five-year global study of human migratory history, analyzing genetic samples from indigenous peoples and public participants. Researchers will use markers encoded into DNA to trace lineages, unveiling new aspects of family trees that persist through genes.
The study reveals that Iraqi Turkmen are a well-educated population with high socio-economic circumstances, contributing to forced migration. The report emphasizes the importance of Turkmen participation in Iraq's reconstruction and suggests their valuable human resource can aid in rebuilding efforts.
University of Wisconsin-Madison researchers used a computer-modeling program to project 200 years of change in a forest in northwestern Wisconsin under three climate scenarios. The model found that some species would not be able to survive warmer conditions, while human actions also contribute to the changing landscape.
A team of researchers at Stanford University used a computer simulation to trace the origins of genetic mutations in human populations. By modeling population growth, migration, and mutation rates, they were able to estimate the location and time of origin for these genetic changes.
A recent study highlights the dangers of communications towers for migrating birds, which mistake tower lights for the moon and collide with structures. The Cornell University meeting brought together experts to discuss solutions, including co-location rules and reduced lighting in tall buildings.
A new study reveals that Hispanics are increasingly settling in the heartland and Sun Belt regions of the US, attracted by job growth and economic opportunities. The fastest growth occurred in states such as Georgia, Maryland, Nebraska, Iowa, Minnesota, and Nevada.
A Brown University study reveals that many songbirds migrating south each autumn switch from insects to a berry-rich diet to store fat for the long haul. The study found that these 'pit stops,' crucial for tiny songbirds traveling thousands of miles, are under intense development and ecological pressure.
