Biology

This course is a combination of lectures, student presentations and group discussions that address fundamental principles and also contemporary issues examining the way all forms of Life on Earth are ultimately dependent on sunlight to satisfy their food and energy requirements. We examine the steps from the capture of Physical energy (photons), to the development of electrochemical potentials and finally, to their utilization by cellular organelles towards the synthesis of the chemical "currency" that fuels all biological processes (biosynthesis, cell communication, movements, etc.). Special emphasis will be on current developments in biotechnologies that utilize microbial populations to supply us with fuels and also to clean up environmental hazards. The course will also consider ways to extract lessons from Nature's successful designs and harmonious adaptations so that we, in the long run, can utilize them towards a minimization of our negative impact on the environment.Note: Freshmen and Sophomores only, with good foundations in any two of the following: Physics, Chemistry, Biology, Biophysics.

MCB MS students with instructor's permission during ADD/DROP Period.

Area: Natural Sciences

This course examines how recently developed single-molecule methods have enhanced our understanding of cellular processes. The ability to observe and manipulate individual biological macromolecules has revolutionized our understanding of the machines and processes that enable life. The course will provide an overview of single-molecule approaches and discuss relevant publications that exemplify how these methodologies are applied to biological problems. For each approach, key concepts will be introduced in a lecture/discussion, followed by a student-led presentation of a related publication.

Area: Natural Sciences

This course examines modern concepts in genetics and molecular biology. The coursefocuses on the mechanisms controlling replication, recombination, transcriptional, posttranscriptional, translational, and posttranslational regulation. Lectures will have threeparts: a student-led paper presentation, a discussion about the concepts surrounding atopic, and a discussion of modern techniques to experimentally probe the topic.Biology PHD students only.

Students will be given instruction in the concepts of physical and quantitative biology. Students will learn to simulate biological processes, identify the relationship between data and models, and will learn to fit biological data. Note: Friday classes will be held in UTL 398.

This course addresses the basic principles that underlie physiological processes in animals. Framed in an evolutionary context, processes ranging from respiration, circulation, neural control, movement, excretion and metabolism will be understood in terms of core principles that also apply to humans. Emphasis is placed on the physical and chemical principles underlying the comparative biology of how different animals solve physiological problems.

The creation and implementation of new approaches to the drug discovery and development process is a very active area of research. Currently, only one compound out of 5,000 that enter preclinical studies becomes a drug. Moreover, the development process is time consuming, lasting more than ten years on average. The rate of failure is extremely high. It has become evident that this field is in urgent need of revolutionary changes. This course will cover drug discovery issues ranging from the identification of hits to their optimization as drug candidates. Current as well as novel and proposed approaches aimed at accelerating discovery, potency optimization, selectivity, pharmacokinetics and other drug properties will be discussed. Grad students only.

All aspects of cell biology are reviewed and updated in this intensive course through critical evaluation and discussion of the current scientific literature. Topics include protein trafficking, membrane dynamics, cytoskeleton, signal transduction, cell cycle control, cell physiology, and the integration of these processes in neurons. Recommended Course Background: AS.020.306

This course provides foundational and multi-tiered training in career strategy and professional development. Through synchronous and asynchronous classes, students will learn to assess and develop the skills needed to transition into a career and align them to their strengths, values and interests. By engaging in small group discussions, experiential learning activities and networking with alumni experts, students will enhance self-knowledge and confidence to explore wider career opportunities. Biology 3rd year and above students only

This is the second course in a two-part series that provides foundational and multi-tiered training in career strategy and professional development. Through synchronous and asynchronous classes, students will learn to assess and develop the skills needed to transition into a career and align them to their strengths, values and interests. By engaging in small group discussions, experiential learning activities and networking with alumni experts, students will enhance self-knowledge and confidence to explore wider career opportunities. This course provides in-depth understanding of specific career paths based on the career exploration covered in 020.688. Biology 3rd year and above students only.

Prerequisite(s): AS.020.688

This course involves discussions of ethical conduct and the responsible practice of scientific research.Department signature only; restricted to graduate students in Biology PhD students only.

The purpose of this course is to gain experience in critical thinking about the logic and methods used in modern biological research. The main approach will be the critical reading, presentation, and discussion of primary research papers, and the preparation and presentation of a research proposal. It is held once a week on the NIH Bethesda campus. Grad students only.
