The world’s best known writer of science fiction, Sir Arthur C Clarke was the first to propose satellite communications in 1945. One of his short stories inspired the World Wide Web, while another was later expanded to make the movie 2001: A Space Odyssey, which he co-wrote with director Stanley Kubrick. He has lived in Sri Lanka since 1956. This is the final video of a remarkable man of optimism and vision for us to cherish forever:
In an exclusive preview of his new book, The Stuff of Thought, Steven Pinker looks at language, and the way it expresses the workings of our minds. By analyzing common sentences and words, he shows us how, in what we say and how we say it, we’re communicating much more than we realize
Can we create new life out of our digital universe?” asks Craig Venter. And his answer is, yes, and pretty soon. He walks the TED2008 audience through his latest research into “fourth-generation fuels” — biologically created fuels with CO2 as their feedstock. His talk covers the details of creating brand-new chromosomes using digital technology, the reasons why we would want to do this, and the bioethics of synthetic life. A fascinating Q&A with TED’s Chris Anderson follows .
To reduce the severity of his seizures, Joe had the bridge between his left and right cerebral hemisphers (the corpus callosum) severed. As a result, his left and right brains no longer communicate through that pathway. This is an extraordinary insight into the machinary of the mind. Here’s what happens as a result:
I have been following JoVE is the Journal of Visualized Experiments, for some time. This very unique “video journal” focuses on publishing videos of experimental procedures in life sciences.
Today I learned JoVE may soon be indexed on Pubmed, which will give it a credibility of peer reviewed scientific journal. Apparently they have also signed agreement with established science publishing companies (Annual Reviews, Springer Protocols, Current Protocols) for joint protocol publication, as in this example.. I think this is extremely useful for scientists or those who want to see actual experiments done. It will be interesting to see how it develops and accepted in scientific community.
This is a very informative animation of how DNA is packaged and replicated within the cell nucleus. [Youtube=http://www.youtube.com/watch?v=5UoKYGKxxMI]
Biological engineering does not have to be confined to the laboratories of high-end industry laboratories. Rather, it is desirable to foster a more open culture of biological technology. This talk is an effort to do so; it aims to equip you with basic practical knowledge of biological engineering.
