Dr. Laura Landweber - "Epigenetics: Rewriting the information in DNA"
"Epigenetics: Rewriting the information in DNA" Dr. Laura Landweber - Princeton University, Dept of Ecology and Evolutionary Biology Global DNA rearrangements occur in many cells, including several forms of cancer. The phenomenon is most exaggerated in some single-celled organisms known as ciliates. I will show how RNA molecules can provide a scaffold to orchestrate these DNA rearrangements, unveiling a new role for RNA in the cell. This provides an example of epigenetics, a term that describes
Dr. Ralph Pudritz - "From First Stars to First Life"
"From First Stars to First Life" Dr. Ralph Pudritz - McMaster University, Origins Institute, and Physics & Astronomy How did life arise on Earth? Are we alone? These are among the oldest and most profound human questions. Life as we know it requires rocky planets that have liquid water and carbon rich molecules such as amino acids -- the building blocks of proteins. All of these basic ingredients for life are the products of the formation and evolution of stars. This talk will trace the remarka

2.75 Precision Machine Design (MIT)
Intensive coverage of precision engineering theory, heuristics, and applications pertaining to the design of systems ranging from consumer products to machine tools. Topics covered include: economics, project management, and design philosophy; principles of accuracy, repeatability, and resolution; error budgeting; sensors; sensor mounting; systems design; bearings; actuators and transmissions; system integration driven by functional requirements, and operating physics. Emphasis on developing cre
6.004 Computation Structures (MIT)
6.004 offers an introduction to the engineering of digital systems. Starting with MOS transistors, the course develops a series of building blocks — logic gates, combinational and sequential circuits, finite-state machines, computers and finally complete systems. Both hardware and software mechanisms are explored through a series of design examples. 6.004 is required material for any EECS undergraduate who wants to understand (and ultimately design) digital systems. A good grasp of the mat
Geraldine the Giraffe Learns About /Ww/
In this cute video, Geraldine the Giraffe learns about the letter /Ww/. She learns to say the sound correctly and looks for things in her house that begin with /Ww/. She finds a wolf, a block of wood, a wallet, and Prince William. This is a great resource to introduce and/or review alphabet letters and sounds in the early childhood classroom. (4:01)

21F.501 Beginning Japanese I (MIT)
This course covers Lessons 1 through 6 from Japanese: the Spoken Language, Part 1 (by Eleanor H. Jorden with Mari Noda, Yale University Press, 1987), providing opportunities to acquire basic skills for conversation, reading and writing. The program emphasizes ACTIVE command of Japanese, not passive knowledge. The goal is not simply to study the grammar and vocabulary, but to acquire the ability to use Japanese accurately and appropriately with increasing spontaneity. Students learn Hiragana
Thurgood Marshall: Biography
Thurgood Marshall, born on July 2, 1908 in Baltimore, Maryland, studied law at Howard University. As counsel to the NAACP, he utilized the judiciary to champion equality for Black Americans. In 1954, he won the Brown v. Board of Education case, in which the Supreme Court ended racial segregation in public schools. Marshall was appointed to the Supreme Court in 1967 and served for 24 years. In this video clip, learn more about activist Thurgood Marshall. (2:13)

Rare Seahorse Filmed for the First Time
October 11, 2012 — The rare West African seahorse has been filmed in the wild for possibly the first time. Researchers hope to learn more about the species and help create a more sustainable trade in the animal. It's estimated that around 150 million seahorses are sold annually for traditional medicine worldwide. (01:13)
NASA | Gradient Sun
Watching a particularly beautiful movie of the sun helps show how the lines between science and art can sometimes blur. But there is more to the connection between the two disciplines: science and art techniques are often quite similar, indeed one may inform the other or be improved based on lessons from the other arena.
