In 1958, Matthew Meselson and Frank Stahl published the "most beautiful experiment", where they demonstrated that DNA undergoes semi-conservative replication. In this video, we describe the experiments that lead to this discovery and why understanding how DNA replicates is so important. This video is a complement to Matthew Meselson's iBiology Discovery talk, where Meselson recalls the events that led him to meet Frank Stahl and to plan and execute these experiments.
This video was produced in collaboration with iBiology.
iBiology (www.ibiology.org) is a growing collection of free open-access online videos by scientists about research and discoveries in fields including cell biology, neuroscience, molecular biology, microbiology, ecology, development, and biophysics, and also features short talks on topics such as professional development, careers, policy, and education. iBiology is funded by NSF, NIGMS, and HHMI, and is supported by the ASCB and UCSF.

Feelings are often associated with physical reactions: terror can send chills down your spine, and love can leave you weak in the knees. A recent study has linked specific emotions to physical sensations. Researchers tested emotional responses in hundreds of subjects and then created maps identifying locations in the body where emotions cause physical changes.

Sexual behavior, romance, and partnerships are among the strongest human social drives. In this session we delve into the biology of sexual behavior and such topics as love addictions, serial monogamy, clandestine adultery, hookup culture, and how human partnering psychology is reflected in our animal cousins.

Why do we sleep? Why do we dream? How conscious are we during sleep and dreams? Neurologist Mélanie Boly explains the important ongoing studies at The Center for Sleep and Consciousness at University of Wisconsin.
During the past four decades, molecular biology has dominated the life sciences. Curiously, no participant in this scientific revolution has previously attempted a book-length history of the development of this powerful science. Harrison ("Hatch") Echols provides such an account in Operators and Promoters. A gifted molecular biologist and talented raconteur, Echols relates the intellectual history of the most influential discoveries in molecular biology from his own experiences.

THNKR is honored to present excerpts from the WWW conference. The WWW conference, created by author, architect, and TED founder, Richard Saul Wurman, generates compelling conversations by pairing "amazingly interesting individuals prompted by a question." Theoretical physicist, Jeffrey West, explores the scaling principles of biology and how they compare to those of urban populations. The results are profound and alarming.
