Living cells have unique functions that can be harnessed by engineers to tackle human problems in energy, water, food, and health.

Historically living cells were considered too difficult to predictably engineer because of their complexity, vulnerability, and continuous change in state. The elucidation of the design principles that underlie cell function along with increasing numbers of examples of hybrid cell based devices are slowly erasing that notion.

In this class you will be learn about these established and emerging cellular design principles and begin to view cells as machines. This knowledge can also then be applied to non-living devices that mimic and communicate with cells. You will also be introduced to current and emerging living/non-living biohybrid devices such as biohybrid robots and neural implants.

Have you ever wondered why humans walk on two legs rather than four? In this course, we will explore how science investigates this unusual form of locomotion. We will start our investigation by looking at the mechanics of upright walking in humans and comparing that to bipedal locomotion in large birds, bears, and apes.

We will journey back millions of years into the human fossil record in an effort to understand how and why upright walking evolved. Around our first birthday, each of us learned how to walk, but how does this happen? With bipedalism came costly trade-offs as well-- we’ll examine these aches and pains as byproducts of our evolutionary history.

This course will take an intentionally interdisciplinary approach to studying how and why humans move bipedally. You will be exposed to anthropology, biomechanics, anatomy, evolution and paleontology to explore something deeply human: upright walking.

This course was developed in collaboration with SmithsonianX (National Musuem of Natural History and the National Zoological Park).

We will explain how to start with raw data, and perform the standard processing and normalization steps to get to the point where one can investigate relevant biological questions. Throughout the case studies, we will make use of exploratory plots to get a general overview of the shape of the data and the result of the experiment. We start with RNA-seq data analysis covering basic concepts of RNA-seq and a first look at FASTQ files. We will also go over quality control of FASTQ files; aligning RNA-seq reads; visualizing alignments and move on to analyzing RNA-seq at the gene-level: counting reads in genes; Exploratory Data Analysis and variance stabilization for counts; count-based differential expression; normalization and batch effects. Finally, we cover RNA-seq at the transcript-level: inferring expression of transcripts (i.e. alternative isoforms); differential exon usage. We will learn the basic steps in analyzing DNA methylation data, including reading the raw data, normalization, and finding regions of differential methylation across multiple samples. The course will end with a brief description of the basic steps for analyzing ChIP-seq datasets, from read alignment, to peak calling, and assessing differential binding patterns across multiple samples.

Given the diversity in educational background of our students we have divided the series into seven parts. You can take the entire series or individual courses that interest you. If you are a statistician you should consider skipping the first two or three courses, similarly, if you are biologists you should consider skipping some of the introductory biology lectures. Note that the statistics and programming aspects of the class ramp up in difficulty relatively quickly across the first three courses. By the third course will be teaching advanced statistical concepts such as hierarchical models and by the fourth advanced software engineering skills, such as parallel computing and reproducible research concepts.

These courses make up 2 XSeries and are self-paced:

PH525.1x: Statistics and R for the Life Sciences

PH525.2x: Introduction to Linear Models and Matrix Algebra

PH525.3x: Statistical Inference and Modeling for High-throughput Experiments

In the PH525 case studies, we will explore the data analysis of an experimental protocol in depth, using various open source software, including R and Bioconductor. We will explain how to start with raw data, and perform the standard processing and normalization steps to get to the point where one can investigate relevant biological questions. Throughout the case studies, we will make use of exploratory plots to get a general overview of the shape of the data and the result of the experiment.

The cell is a powerful case study to help us explore the functional logic of living systems. All organisms, from single-celled algae to complex multicellular organisms like us, are made up of cells. In this course, you will learn the how and why of biology by exploring the function of the molecular components of cells, and how these cellular components are organized in a complex hierarchy.

This course is designed to explore the fundamentals of cell biology. The overarching goal is for learners to understand, from a human-centered perspective, that cells are evolving ensembles of macromolecules that in turn form complex communities in tissues, organs, and multicellular organisms.

We will focus, in particular, on the mitochondrion, the organelle that powers the cell. In this context, we will look at the processes of cell metabolism. Finally, we will examine the F1F0 ATP synthase, the molecular machine that is responsible for the synthesis of most of the ATP that your cells require to do work. To underscore the importance of cell biology to our lives, we will address questions of development and disease and implications of science in society.

By the end of four weeks, we hope learners will have a deep intuition for the functional logic of a cell. Together we will ask how do things work within a cell, why do they work the way they do, and how are we impacted?

Join us as we explore the extraordinary and wonderfully dynamic world of the cell.

Brain and behavior are inextricably linked in neuroscience. The function of the brain is to govern behavior, and the aim of this course is to causally link biophysical mechanisms with simple behaviors studied in mice. The brain processes information through the concerted activity of many neurons, which communicate with each other through synapses organised in highly dynamic networks. The first goal of the course is to gain a detailed understanding of the structure and function of the fundamental building blocks of the mammalian brain, its synapses and neurons. The second goal is to understand neuronal networks, with specific emphasis on the interactions of excitatory glutamatergic and inhibitory GABAergic neurons. The third goal is to place neuronal network function in the context of sensory processing ultimately leading to behavioral decisions and motor output.

Every day, we see concrete used all around us – to build our houses, offices, schools, bridges, and infrastructure. But few people actually understand what gives concrete its strength, resistance, and utility.

The aim of this course is to offer basic cement chemistry to practitioners, as well as new students in the fields of chemistry and engineering.

You will learn how cement is made and hydrated, as well as the environmental and economical benefits it offers. You’ll learn to test your samples in isocalorimetry in order to track the hydration and to prepare and observe samples by scanning electron microscopy. In the last two weeks of the course, you will also learn how X-ray diffraction works and how to apply it to cements.

Because the course is designed for beginning students, it’s not necessary to have a cement background, however basic concepts in chemistry and crystallography will help. This course lasts 6 weeks, during which you can take theoretical courses and tutorials to test the cement in the laboratory.
