Summary
The Washington State Twin Registry (WSTR) has expanded its research capabilities, including recruiting younger participants and developing environmental exposure data. This update details its growth and future directions in twin research.
Area of Science:
- Human Genetics
- Twin Research
- Epidemiology
Background:
- Twin registries are crucial resources for scientific research.
- The field of twin research has advanced significantly since 2013.
- This article updates the scientific community on the Washington State Twin Registry (WSTR).
Purpose of the Study:
- To provide current information on the Washington State Twin Registry (WSTR).
- To summarize the registry's history, construction, member characteristics, and data.
- To outline WSTR's research goals, recent studies, and future directions.
Main Methods:
- Summarizing historical and construction methods of the WSTR.
- Describing member characteristics and available data.
- Detailing WSTR's growth, including youth recruitment, geocoding for environmental exposures, and biobank expansion.
Main Results:
- The WSTR has grown in size and scope since its last description in 2013.
- Recruitment now includes youth pairs under 18.
- Environmental exposures have been developed through geocoding and linked to health data; a biobank has been expanded for various 'omics' studies.
Conclusions:
- The Washington State Twin Registry is a continuously evolving resource for scientific research.
- Recent expansions enhance its utility for studying genetic and environmental influences on health.
- Future research directions leverage integrated data and bio-specimens for advanced analyses.

Measurement is an indispensable part of analytical chemistry. The result of measurement helps quantify a substance's physical property and compare it with the physical property of another substance. Each measurement comprises two components - a number indicating the magnitude and a unit of measurement as a standard for comparison. Further, the same quantity can be measured using different units of measurement, which leads to differences in magnitude.

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
