Possibly my favourite science article of 2013 so far. It makes sense in terms of evolutionary adaption since astral light sources would be an evolutionary environmental constant so adapting to utilize them makes a lot of sense. Proving that dung beetles do this - is just a wow. cool artile worth reading.

Will we ever… reveal all the secrets of life from DNA?

Will we ever… reveal all the secrets of life from DNA? | Information, Complexity, Computation | Scoop.it

Good article on the BBC Future website : As our technologies and understanding advance, will we eventually be able to look at a pile of raw DNA sequence and glean all the workings of the organism it belongs to? Just as physicists can use the laws of mechanics to predict the motion of an object, can biologists use fundamental ideas in genetics and molecular biology to predict the traits and flaws of a body based solely on its genes? Could we pop a genome into a black box, and print out the image of a human? Or a fly? Or a mouse?

Not easily... Click on the image or the title to learn more.

What's quantum physics got to do with biology?

Tonight at the World Science Festival, astrophysicist Paul Davies and quantum computing innovator Seth Lloyd will talk about the growing field of quantum biology—why it works, what it means, and how it might shape our future. The Bad News: The Festival is happening in New York City and tonight's panel is sold out. The Good News: You can watch a live webcast of the event online at 8:00 Eastern time.  Learn more

Robert Sapolsky lecture on emergence and complexity.

Professor Robert Sapolsky gives a lecture (May 2010) on emergence and complexity.  Robert is Professor of Biological Sciences, and Professor of Neurology and Neurological Sciences at Stanford University and is a research associate with the National Musuems of Kenya. Essential watching for those just starting to learn about complex systems and system properties such as emergence and guided formation rules.  Worth watching.

Antibiotic 'apocalypse' warning

Antibiotic 'apocalypse' warning | Information, Complexity, Computation | Scoop.it
The rise in drug resistant infections is comparable to the threat of global warming, according to the chief medical officer for England.

Perhaps appropriate that Prof Sally Davies used the comparison to global warming in that at least popular press coverage of antibiotic resitatnce tends to either saw from the dismissive to the apocalyptic. Good interview by the BBC - worth reading.

Life and fuzziness

Life and fuzziness | Information, Complexity, Computation | Scoop.it

Many scientists have devoted time to try to find a definition for life, in spite of the differences the large majority of life definitions rely on the dichotomy living vs. non-living. Bruylants and colleagues argue that “it is indeed impossible to define a natural frontier between non-living and living systems and therefore also impossible to define dichotomic criteria which could be used in order to classify systems in one of these two classes (living or non-living)”. Thus authors conclude that “fuzzy logic provides a natural way to deal with problems where class membership lacks sharply defined criteria”, proposing a paradigmatic shift…a truly needed one. Great piece of work, highly raccommended.
