Oocytes are prone to aneuploidy due to errors in chromosome segregation during meiotic maturation. Aneuploid eggs can cause infertility, miscarriages or developmental disorders like Down syndrome. Here, we describe methods to introduce materials of choice into oocytes and methods to study meiotic maturation and assess ploidy.

Maturation of Endosomes

The early endosome containing internalized molecules matures through transformations in its location, morphology, intraluminal pH, and membrane protein composition. Together, these changes result in a more acidic late endosome that contains multiple intraluminal vesicles; therefore, the late endosome is also called a multivesicular body (MVB). Changes in location The maturing endosome moves along microtubules from the periphery of the cell towards the perinuclear region. This movement of the...

This video presents synthetic biology and its role in bioengineering. Synthetic biology refers to the methods used to genetically modify organisms in order to make them capable of producing large quantities of a product. This product could be a protein that the cell already makes or a new protein that has been encoded in a newly-inserted DNA sequence. Here, we discuss how an organism's genetic material is modified using transformation or transfection. Then, the process is shown in the...

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials. Ecosystems also perform critical services, such as purifying our air and water. A large body of evidence indicates that such ecosystem services depend on biodiversity. Furthermore,...
FAQs
Biological maturation is guided genetically but not rigidly predetermined. Environmental conditions can influence when developmental changes appear and how strongly they are expressed. This means researchers examine timing and expression together rather than treating biology as independent of context. In psychology, that perspective helps explain why people may show different developmental patterns even when underlying biological processes are broadly comparable.
Changes in the brain and nervous system do not occur in isolation from the rest of biological development. Hormonal activity, physical growth, and increasing neural organization operate as coordinated processes, and their relationship can support shifts in cognition, emotion, social behavior, and physical capabilities. This systems perspective is especially relevant when interpreting developmental changes during infancy, puberty, and adolescence.
Timing is a central variable in biological maturation. Developmental changes may be examined not only by what changes occur, but also by when they occur. Earlier or later timing can be considered alongside environmental conditions, because context may influence the expression of development. In psychology, this supports study of individual differences and developmental pathways without assuming that all people change at the same pace.
To distinguish biological maturation from learning, psychologists can relate changes in behavior to concurrent changes in physical growth, hormonal activity, brain development, or neural organization, while also considering experience and environmental conditions. This comparison does not remove the role of learning. Instead, it helps researchers examine how biologically guided change and experience may contribute to cognition, emotion, and social behavior.
During infancy, puberty, and adolescence, biological maturation helps organize questions about why capabilities and behaviors change at particular developmental periods. Researchers can examine cognition, emotion, social behavior, and physical capabilities in relation to ongoing biological changes. The approach is useful for studying developmental timing and for identifying how environmental conditions may shape the expression of those changes across individuals.
Biological maturation helps researchers interpret changes in cognition, emotion, social behavior, and physical capabilities as connected developmental outcomes. Studying these domains together can clarify how brain development, hormonal activity, physical growth, and neural organization relate to behavior. It also supports research on individual differences, developmental timing, health outcomes, and interactions between biological processes and environmental influences.
