Spring into Hope

Turning Hope Thoughts Into Goal-Directed Behavior

well-being might result. Similarly, insofar as perceiving the good things in one's life as the result of the intentional benevolence of another person or persons makes those benefits even more enjoyable, it is easy to imagine how one might be happier and healthier as a result. Obviously, much of daily life occurs without conscious control and without a second thought. Nonetheless, some people m...

Cohesin and condensin spring into action

Retinoic acid keeps Lingo-1 quiet R etinoic acid (RA) promotes axon regeneration by silencing a key inhibitory receptor, Puttagunta et al. report. Neuronal regrowth after injury is limited, in part, by inhibitory proteins released upon disruption of the surrounding myelin sheath. These proteins bind to the Nogo receptor complex on the neuronal plasma membrane, thereby activating the RhoA GTPase...

Hope against Hope

In the penultimate chapter of the Bible, in the opening statement of the very last speech God makes in the whole of the Christian Scriptures, God says: "Behold I am making all things new" (Rev 21:5). The prophet sees the old heavens and the old earth the universe as it now is passing away, and new heavens and a new earth, God's new creation of all things, coming into being. It is not that God r...

On the coarse-graining of polymers into bead-spring chains

We present a study of the coarse-graining of polymers into bead-spring chains using statistical mechanics. The force–extension behavior is examined at different levels of coarse-graining. A direct result of the springs being decoupled is that the force–extension behavior depends only on the number of flexibility lengths (e.g. persistence or Kuhn lengths) represented by each spring. This dimensi...
