The geologic record demonstrates that our environment has changed over a variety of time scales from seconds to billions of years. This course explores the many ways in which geologic processes control and modify the Earth's environment and serves as an introduction to Environmental Earth Science Field Course (12.120), which addresses field applications of these principles in the American Southwest.

This course covers introductory microbiology from a systems perspective, considering microbial diversity, population dynamics, and genomics. Emphasis is placed on the delicate balance between microbes and humans, and the changes that result in the emergence of infectious diseases and antimicrobial resistance. The case study approach covers such topics as vaccines, toxins, biodefense, and infections including Legionnaire’s disease, tuberculosis, Helicobacter pylori, and plague.

Chemistry and biology are traditionally taught as separate subjects at the high school level, where students memorize fundamental scientific principles that are universally accepted. However, at the university level and in industry, we learn that science is not as simple as we once thought. We are constantly confronted by questions about the unknown and required to use creative, integrated approaches to solve these problems. By bringing together knowledge from multidisciplinary fields, we are empowered with the ability to generate new ideas. The goal of this course is to develop skills for generating new ideas at the interface between chemistry and biology by analyzing pioneering studies.

Each part of the world faces specific vulnerabilities to climate change and has different opportunities to mitigate the effects and build resilience in the 21st century. With the Paris Agreement at COP 21, the global community has signaled its intent to act. Indeed, without climate action, decades of development progress are threatened, meaning that we are at a ‘make it or break it’ point in time. This course presents the most recent scientific evidence, regional impacts and climate action strategies, and some opportunities for you to take action on climate change.

During each week of this course, chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Inspired by such cooking mastery, the Harvard team will then explain the science behind the recipe.

Topics will include:

• How molecules influence flavor
• The role of heat in cooking
• Diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià.

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen. By following along with the engaging recipe of the week, taking precise measurements, and making skillful observations, you will learn to think like both a cook and a scientist. The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

Join us for the Sochi 2014 Winter Olympics! Mega-events like the Olympics are complex phenomena that combine decisions about a short-term festival with long-term social impacts. On the surface, the public spectacle is compelling but going inside the games reveals so much more about the event, athletes, and host city. We will explore the many dimensions of mega-events—history, culture, politics, business, law, sports management, health, and economics—and provide the tools and language to interpret and understand the 2014 Winter Olympics. Join us, and fans around the world, for a month of Olympic spectacle.

From understanding social identities to modeling the spread of disease, this eight-week course will span key science and survival themes using AMC’s The Walking Dead as its basis. Four faculty members from the University of California, Irvine will take you on an inter-disciplinary academic journey deep into the world of AMC’s The Walking Dead, exploring the following topics: Maslow’s hierarchy of needs—is survival just about being alive? Social order and structures—from the farm and the prison to Woodbury Social identity, roles, and stereotyping—as shown through leaders like Rick and the Governor The role of public health in society—from the CDC to local community organizations The spread of infectious disease and population modeling—swarm! The role of energy and momentum in damage control—how can you best protect yourself? Nutrition in a post-apocalyptic world—are squirrels really good for you? Managing stress in disaster situations—what’s the long-term effect of always sleeping with one eye open? Each week we’ll watch engaging lectures, listen to expert interviews, watch exclusive interviews with cast members talking about their characters, use key scenes from the show to illustrate course learning, read interesting articles, review academic resources, participate in large and small group discussions, and—of course—test our learning with quizzes. We recommend that you plan on spending about two (2) to four (4) hours per week on this course, though we believe the course is compelling enough you’ll want to spend more time. At the end of this course, you will be able to: Describe how infectious diseases—like a zombie epidemic—spread and are managed Apply various models of society and Maslow’s hierarchy of needs to existing and emerging societies as a means for understanding human behavior Analyze existing social roles and stereotypes as they exist today and in an emerging world Debate the role of public health organizations in society Describe how mathematical equations for population dynamics can be used to study disease spread and interventions Apply concepts of energy and momentum appropriately when analyzing collisions and other activities that either inflict or prevent damage Summarize multiple methods for managing stress in disaster situations

This introductory course in biology starts at the microscopic level, with molecules and cells. Before we get into the specifics of cell structure and behavior, however, let’s take a cursory glance at the field of biology more generally. Though biology as we know it today is a relatively new field, we have been studying living things since the beginning of recorded history. The invention of the microscope was the turning point in the history of biology; it paved the way for scientists to discover bacteria and other tiny organisms and ultimately led to the modern cell theory of biology. You will notice that, unlike the core program courses you took in chemistry and physics, introductory biology does not have many mathematical “laws” and “rules” and does not require much math. Instead, you will learn a great number of new terms and concepts that will help you describe life at the smallest level. Over the course of this semester, you will recognize the ways in which the tiniest of molecules are involved…

Welcome to BIO101B, Introduction to Molecular and Cellular Biology.  This course is intended for the student interested in understanding and appreciating common biological topics in the study of the smallest units within biology: molecules and cells. Molecular and cellular biology is a dynamic field.  There are thousands of opportunities within the medical, pharmaceutical, agricultural, and industrial fields (just to name a few) for a person with a concentrated knowledge of molecular and cellular processes.  This course will give you a general introduction of these topics.  In addition to preparing for a diversity of career paths, an understanding of molecular and cell biology will help you make sound decisions in your everyday life that can positively impact your diet and health. Note that this course is an alternative to BIO101A [1], and that you may choose to take either BIO101A or BIO101B in order to learn about Molecular and Cellular Biology.  These courses cover the same material, but in a slig…

This lab course supplements BIO302: Human Anatomy [1].  Although we cannot virtually replicate the lab experience, this “lab” will familiarize you with scientific thinking and techniques and will enable you to explore of some key principles of human anatomy. The material in this lab supplement relates to the material covered in the lecture and reading portion of the course.  While that portion focuses more on large-picture concepts, here we will focus more on visual understanding, manipulation, and practical use of your knowledge.  You will review the anatomy and histology of the organs by using images of models, microscopic slides, and videos on cat and sheep dissections.  Then you will be asked to assess your knowledge, which eventually can be put to practical or experimental use.  Working though this lab supplement, you will realize that you must memorize new terms and locate different structures and organs, which can only be achieved by repetition and practice. Note: This course makes use of…

This course will teach you the fundamentals of thermodynamics. Thermodynamics is the study of energy and its transformations. Energy is a physical property that can be converted from one form to another in order to perform work. For example, a stone rolling down a hill is converting gravitational potential energy into the kinetic energy of motion. Thermodynamics can be applied to systems we use every daysuch as, for example, heat pumps and refrigerators, internal combustion engines, batteries, and both electrical and mechanical power generators. An awareness of thermodynamics will help you examine other concepts involving chemical processes more quickly and will enable you to understand why many physical phenomena (such as automobile engines or chemical explosives) work the way they do. The knowledge you will gain in this course also will help you determine how much work an object can put out and predict how to optimize an object’s operation. In this course, you will learn about the laws of thermodynamics…

This course will teach you the important role that metal ions play in key biological processes.  You will learn that many biological functions are performed at the cellular level by metal ions that are incorporated into the activation sites of proteins and enzymes.  For example, when oxygen is transported through blood in the human body, it is bound to iron ions that are incorporated into the hemoglobin protein.  In order to function properly, these iron ions must be high-spin and in their +2 oxidation state.  As you progress through this course, you will learn about these and other requirements and mechanisms that must be present in order to facilitate critical biological functions. You will begin this course by reviewing the basic principles of inorganic chemistry, biochemistry, and molecular biology.  Following a brief overview of the spectroscopy methods that scientists use in the study of metals that contain protein, you will explore the structures of the most relevant metal centers in biological…

Bioorganic chemistry studies the chemistry of organic biomolecules.  It is a rapidly growing interdisciplinary field that combines organic chemistry and biochemistry.  Please recall that organic chemistry investigates all molecules that contain carbon and hydrogen, and biochemistry focuses on the network of molecular pathways in the cell.  Bioorganic chemistry employs organic chemistry to explain how enzymes catalyze the reactions of metabolic pathways and why metabolites react the way they do.  Bioorganic chemistry aims to expand organic-chemical research on structures, synthesis, and kinetics in a biological direction. This one-semester course will cover several advanced chemistry topics and will discuss the chemistry behind biological processes.  The course begins by introducing you to the mechanisms behind the most common biological chemical reactions (Unit 1).  You will then take a closer look at the metabolic processes of biomolecules.  You will apply your knowledge of the structural feature…
