Spontaneous muscle twitches during sleep guide spinal self-organization
Article Abstract:
Computer simulation of spontaneous muscle twitches using a correlation-based learning mechanismsensorimotor explains the functional adaptation of the withdrawal reflex system in spinal reflex systems. Furthermore, tactile feedback from sleep generated spontaneous muscle twitches modify sensorimotor transformation in young rats. Data indicate that such fetal movement-associated twitches facilitate spinal self-organization.

Signal sequence directs localized secretion of bacterial surface proteins
Article Abstract:
N-terminal signal sequence in bacteria Streptococcus pyogenes is studied. It is seen that the signal sequences of two surface proteins, M protein and protein F (PrtF) direct secretion to different sub cellular region indicating that a signal sequence may contain information that directs the secretion of a protein to one subcellular region, in addition to its role in promoting secretion.

Effects of species and functional group loss on island ecosystem properties
Article Abstract:
A group of 30 islands in northern Sweden, for which island size determined disturbance history, and therefore vegetation successional stage and biotic and abiotic ecosystem properties is studied. The study provides evidence that the consequences of biotic loss for ecosystem functioning vary greatly among ecosystems and depend on the specific abiotic attributes of the system.
