What is the HHMI? Why is it amazing?
I visited the Howard Hughes Medical Institute last week.
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Great Discoveries in Science: The Double Helix
The Double Helix is the story of the scientists and evidence involved in one of the most important scientific quests of the 20th century: the discovery of the structure of DNA. [16:53]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: The Origin of Species: The Making of a Theory
The epic voyages of Darwin and Wallace led each to independently discover the natural origin of species and to formulate the theory of evolution by natural selection. [30:51]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: The Origin of Species: Lizards in an Evolutionary Tree
In the Caribbean Islands, adaptation to several common habitats has led to a large adaptive radiation with interesting examples of convergent evolution. [17:45]

Hhmi: Bio Interactive: Animation: Triplet Code
Once the structure of DNA was discovered, the next challenge was determining how the sequence of letters coded for the 20 amino acids could make protein. In theory, one or two letters can only code for 4 or 16 amino acids, respectively....

Hhmi: Bio Interactive: Making of the Fittest: Co Evolution of Genes & Culture
Follow human geneticist Spencer Wells, Director of the Genographic Project of the National Geographic Society, as he tracks down the genetic changes associated with the ability to digest lactose as adults, tracing the origin of the trait...

Hhmi: Bio Interactive: Animation: Translation
See this close-up animation showing how ribosomes carry out translation to make a particular proteins. [3:04]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Regulation of Eukaryotic Dna Transcription
General transcription factors, activators, and repressors interact to regulate the transcription of eukaryotic DNA into RNA. [2:05]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Rna Folding
Since RNA is single-stranded, it can fold upon itself and form structures that are protein-like in both appearance and functionality. [0:33]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Lactose Digestion in Infants
A quick video clip that shows the lactase enzyme produced in the small intestine of infants. It digests lactose by breaking it into glucose and galactose. [0:53]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Microarrayer in Action
See how a microarraying robot delivers hundreds of small molecules to a series of slides. [2:00]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: How Tumors Grow
A look inside the birth and life of a tumor. See how the growth begins, and how blood vessels form to support the tumor. [1:12]
Howard Hughes Medical Institute
Hhmi: Bio Interactive: Dna Gene Chip Explanation
Observe a scientist describe the process used to extract DNA from a cell and to analyze it on a gene chip. [1:41]
