Live long and prosper? Decoupling lifespan and healthspan in aging research
(Medical Xpress)—A long-standing assumption in aging research, and therefore in resulting antiaging interventions, is that modifying genetic and environmental factors to extend lifespan also increases healthspan – the length of time an organism is in optimal health. As it turns out, however, that assumption has escaped scientific scrutiny due largely to its apparent validity. Recently, scientists at University of Massachusetts Medical School (UMMS) examined this assumption, and thereby the life-/healthspan relationship, by investigating multiple lifespan-modulating signaling pathways – mechanisms in which ligands (ions or molecules) bind to receptors, resulting in altered cellular responses – in the wild type and four long-lived mutants (insulin/insulin-like growth factor-1, dietary restriction, protein translation, and mitochondrial signaling) of the roundworm Caenorhabditis elegans, a species studied for over two decades in aging research. They found that all long-lived mutants spent a higher percentage of their extended lifespan in a frail, rather than healthy, state. The scientists therefore conclude that aging research must include additional factors beyond lifespan alone.

Neural spines operate like miniature neurons
Nerve cells use a much larger repertoire of data-processing structures than previously thought. Research at LMU and in Regensburg shows that the so-called spines on the dendritic processes of neurons are able to process stimuli locally.

The latest fashion: Graphene edges can be tailor-made
Theorists show it may be possible to tune graphene edges by varying heat and force as graphene is fractured. Edge configurations affect graphene's electronic and mechanical properties, which are important for applications.
