If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Connecting to our ongoing discussion in these pages over the likelihood that we will be able to recognize alien life, the multiplicity of possible forms life probably takes, and the difficulties of knowing how to scan for intelligent species, here's some excellent late-summer reading: an article called Could alien life exist in the form of DNA-shaped dust? at...

It would be interesting to ask whether such dust-plasma objects (dasmites? plustets?) could ever (self-) organize into the assemblies required of more complex life.

Very Interesting!

being important for the formation of worlds and its needs?

http://en.wikipedia.org/wiki/RNA_world_hypothesis

looks
to be very close to the article hypothesis, but maybe the rings around Saturn are part of a neccessary formation of multiple planets needed to give life a chance to flourish? it could be the "shape" of DNA to come is moulded by a number of factors, even the medium of light has a function in dictating the geometry of structures?

I guess Sir Fred Hoyle was thinking along similar lines of inquiry:

http://en.wikipedia.org/wiki/Panspermia

Maybe, just maybe the whole solar system's planets have past along via evolution, particular tweaking of attributes to lifes structures?..for instance our racky planet without an atmosphere, may have been beneficial to the formation of certain molocules, then a shower of new molocules may have landed here and instigated a slight change in local thermal quantities at the chemical ground level?
