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.

Abstract:

We learn in undergraduate courses the intimate relationship between entropy and irreversibility: an irreversible process is characterized by an increase of entropy. In the last years and using concepts from information theory, we have been able to quantify irreversibility and relate this measure of irreversibility to the entropy produced along a process. More recently, we have applied these ideas to estimate the entropy production in biophysical processes. Entropy production is closely related to relevant quantities in biophysics which are hard to measure., such as the ATP consumption. Out technique allows one to estimate the entropy production even in the absence of currents and flows, where the standard methods from irreversible thermodynamics fail. We can in principle detect if a system is far from equilibrium in the absence of currents. In biophysics, this is equivalent to discern if a process is active or passive, valuable information to find out the physical mechanisms behind molecular motors and other systems.
