Migration00:53

Migration

8.7K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

Gene Flow02:39

Gene Flow

37.3K
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Cell Migration01:19

Cell Migration

6.3K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell Migration

18.5K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

Gastrulation01:56

Gastrulation

65.6K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Selected Data About Geographic Locations01:25

Selected Data About Geographic Locations

243
Geographic Information Systems (GIS) rely on two core types of data: spatial data and attribute data.Spatial DataSpatial data defines the physical location of features within a coordinate system, typically expressed in terms of latitude and longitude. It provides precise positioning for elements like roads, rivers, or buildings.Attribute DataAttribute data complements spatial data by adding descriptive information about these features. For example, a road's spatial data includes its start and...

Area of Science:

  • Demography
  • Sociology
  • Data Science

Background:

  • Existing US migration data lack spatial granularity or suffer from biases.
  • High-resolution migration data are crucial for understanding demographic, environmental, and health trends.

Purpose of the Study:

  • To develop a novel method for creating high-resolution annual migration matrices.
  • To fuse proprietary and Census data to overcome limitations of existing datasets.
  • To provide a valuable resource for migration researchers.

Main Methods:

  • Developed a data fusion technique combining high-resolution proprietary data with coarse US Census data.
  • Created MIGRATE, annual migration matrices with unprecedented spatial resolution (US Census Block Group pairs).
  • Validated estimates against external ground-truth datasets, demonstrating improved accuracy.

Main Results:

  • MIGRATE captures fine-grained migration flows at ~4,000x the resolution of public data.
  • Analysis revealed national patterns in homophily, upward mobility, and moving distance, including income-based and racial disparities.
  • Identified local migration drivers, such as wildfire-induced out-migration, previously undetectable.

Conclusions:

  • The MIGRATE dataset offers a significant advancement in migration data resolution and accuracy.
  • This resource enables novel analyses of national and local demographic, social, and environmental phenomena.
  • MIGRATE is released to facilitate future research in migration studies.
