Cell Biology Overview

Cell biology is a multifaceted discipline focused on the structure and function of cells, the basic units of living organisms. It involves studying processes such as growth, division, communication, energy production, and waste removal within cells. At the heart of cellular activity lies the nucleus, containing genetic instructions known as DNA. Other essential parts include membranes surrounding structures called organelles, which carry out specialized functions.

Introductory Biology Course Improvements

In recent years, many colleges have implemented research-intensive courses to improve students' skills, confidence, and attitudes towards scientific research and discovery. These courses typically involve active learning through hands-on experiments, data analysis, and scientific writing. Such curricula aim to equip students with the necessary tools for future success in careers related to biology.

Graduate Teaching Assistants' Identities

For graduate teaching assistants (TAs) in introductory biology classes, their roles can vary from teacher to researcher to mentor. These roles are complex and evolve as the class progresses, involving guidance of students in learning and practicing skills needed to excel in biology. Developing a tool to gauge TAs' identification with these roles, called the Biology Teaching Assistant Role Identity Questionnaire (BTARIQ), can reveal insights into their professional development and career aspirations.

Career Opportunities

After completing a degree in biology, one might enter either academia or industry. Academia offers independence and flexibility, whereas industry provides structured environments with set goals. Both paths demand high levels of competence in fields like molecular biology and genetics. Postdoctoral fellows sometimes struggle to find suitable jobs in the fast-changing landscape of biomedical sciences, highlighting the importance of staying up-to-date with emerging technologies and techniques.
