Ways in which ICME sheaths differ from magnetosheaths

Ways in which coherence is confirmation conducive

Recent works in epistemology show that the claim that coherence is truth conducive – in the sense that, given suitable ceteris paribus conditions, more coherent sets of statements are always more probable – is dubious and possibly false. From this, it does not follows that coherence is a useless notion in epistemology and philosophy of science. Dietrich and Moretti 2005 have proposed a formal o...

Three Ways in Which Midline Regions Contribute to Self-Evaluation

An integration of existing research and newly conducted psychophysiological interaction (PPI) connectivity analyses suggest a new framework for understanding the contribution of midline regions to social cognition. Recent meta-analyses suggest that there are no midline regions that are exclusively associated with self-processing. Whereas medial prefrontal cortex (MPFC) is broadly modulated by s...

Historicity of the ways in which knowledge production impacts practice

New ways in which GLP-1 can regulate glucose homeostasis.

Glucagon-like peptide-1 (GLP-1) has a diverse set of peripheral actions which all serve to promote enhanced glucose tolerance, and for this reason it has become the basis for new treatments for type 2 diabetes. In this issue of the JCI, Knauf et al. provide clear evidence that GLP-1 signaling in the CNS is also linked to the control of peripheral glucose homeostasis by inhibiting non-insulin-me...

Individual Oligodendrocytes Have Only a Few Hours in which to Generate New Myelin Sheaths In Vivo

The number of myelin sheaths made by individual oligodendrocytes regulates the extent of myelination, which profoundly affects central nervous system function. It remains unknown when, during their life, individual oligodendrocytes can regulate myelin sheath number in vivo. We show, using live imaging in zebrafish, that oligodendrocytes make new myelin sheaths during a period of just 5 hr, with...
