9.12 Experimental Molecular Neurobiology (MIT)
Designed for students without previous experience in techniques of cellular and molecular biology, this class teaches basic experimental techniques in cellular and molecular neurobiology. Experimental approaches covered include tissue culture of neuronal cell lines, dissection and culture of brain cells, DNA manipulation, synaptic protein analysis, immunocytochemistry, and fluorescent microscopy.
Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors behave the same?
2.797J Molecular, Cellular, and Tissue Biomechanics (MIT)
This course develops and applies scaling laws and the methods of continuum mechanics to biomechanical phenomena over a range of length scales. Topics include structure of tissues and the molecular basis for macroscopic properties; chemical and electrical effects on mechanical behavior; cell mechanics, motility and adhesion; biomembranes; biomolecular mechanics and molecular motors. The class also examines experimental methods for probing structures at the tissue, cellular, and molecular levels.
10.37 Chemical and Biological Reaction Engineering (MIT)
This course applies the concepts of reaction rate, stoichiometry and equilibrium to the analysis of chemical and biological reacting systems, derivation of rate expressions from reaction mechanisms and equilibrium or steady state assumptions, design of chemical and biochemical reactors via synthesis of chemical kinetics, transport phenomena, and mass and energy balances. Topics covered include: chemical/biochemical pathways; enzymatic, pathway, and cell growth kinetics; batch, plug flow and well
HST.161 Molecular Biology and Genetics in Modern Medicine (MIT)
This course provides a foundation for understanding the relationship between molecular biology, developmental biology, genetics, genomics, bioinformatics, and medicine. It develops explicit connections between basic research, medical understanding, and the perspective of patients. Principles of human genetics are reviewed. We translate clinical understanding into analysis at the level of the gene, chromosome and molecule; we cover the concepts and techniques of molecular biology and genomics, an
7.342 Developmental and Molecular Biology of Regeneration (MIT)
How does a regenerating animal "know" what's missing? How are stem cells or differentiated cells used to create new tissues during regeneration? In this class we will take a comparative approach to explore this fascinating problem by critically examining classic and modern scientific literature about the developmental and molecular biology of regeneration. We will learn about conserved developmental pathways that are necessary for regeneration, and we will discuss the relevance of these findings
9.013J Cell and Molecular Neurobiology (MIT)
This course explores the major areas of cellular and molecular neurobiology, including excitable cells and membranes, ion channels and receptors, synaptic transmission, cell-type determination, axon guidance, neuronal cell biology, neurotrophin signaling and cell survival, synapse formation and neural plasticity. Material includes lectures and exams, and involves presentation and discussion of primary literature. It focuses on major concepts and recent advances in experimental neuroscience.
12.458 Molecular Biogeochemistry (MIT)
This course evaluates and discusses the formation and diagnostic structural properties of organic compounds with particular emphasis on those molecules which form chemical fossils. The course is structured around the biosynthetic and phylogenetic origins of recalcitrant hydrocarbons.
Thinkwell Chemistry: Finding Empirical and Molecular Formulas, Part 1 of 2
This is a clip from a larger segment on how to find empirical and molecular formulas. (06:07)
Chain Reaction: Water
Artists using using visual media to capture climate change in the act. The video begins with showing water bottles made from plastic which uses oil to produce the bottles, gas to transport the bottles and the entire planet's resulting consequences of global warming. Speeded up climate changes showing dying coral, rising water levels, hurricanes, ending with a challenge to be concious of the changes and "Sound the Alarm." Set to contemporary music.
Using a Chemical Reaction To Blow Out a Candle
Mixture of baking soda and vinegar produces carbon dioxide. Video shows how to blow out a candle in this experiment. Experiment is set to music, no narration. Grades 5-12. 56 sec.
Chemical Reaction Egg Shell Demonstration
Join Nanna as she demonstrated how vinegar can create a chemical reaction that will dissolve the shell of a raw egg. She uses two glasses, vinegar, water, and two raw eggs to complete her experiment and explains how the acidic acid in the vinegar reacts with the egg shell. The Kids Know It movies bring your student on a fun and interactive journey through the world around us. Run time 06:47
Empirical and Molecular Formulas from Stoichiometry
Empirical and Molecular Formulas from Stoichiometry
This video offers instruction from Sal Khan. This is another stoichiometry example. Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly.
Introduction to Reaction Mechanisms
In this video, Sal Khan offers an introduction to reaction Mechanisms. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. Please open the screen to 'full view' to see the small writing on a black screen.
Molecular and Empirical Forumlas from Percent Composition
The instructor discusses a word problem concerning Molecular and Emperical Forumlas from Percent Composition. This is Example 2.9 from the Kotz Chemistry book. Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly. (10:34)
Molecular Genetics: The Protein vs. DNA Debate
The protein vs. dna debate - Professor George Wolfe discusses molecular genetics and the protein vs. DNA debate in this video from Thinkwell's online Biology series. Run time 09:23.
The program examines isomers and how the electronic structure of a molecule's elements and bonds affects its shape and physical properties. This video explores how molecules with the same numbers and kinds of atoms with very diverse shapes can be very different in properties.
Reaction to New Immigration- late 1800s
This video is accompanied by text. "The influx of millions of new immigrants into America’s cities had a powerful effect on city governments. At the time, state and federal governments did little to help immigrants adjust to their new lives in America, leaving city governments burdened with the enormous task. Due to the rapid rate of urban growth, cities could scarcely keep up with city dwellers' needs for transit, water, sewers, street cleaning, and fire and police protection. This lack of go
Learn about the Maillard Reaction with Cooking
Believe it or not, steak, coffee beans, caramel, and toast have something in common. It's called The Maillard Reaction and it is the reason that things get browned when they are heated. It is a chemical reaction of sugars with amino acids. Dr. Kiki helps explain this process. Run time 03:38
