Arthropods are the most numerous animals on Earth, with the phylum Arthropoda being divided up into five subphyla of which four are extant. These are hexapods (insects), crustaceans (crabs, shrimps etc.), chelicerates (spiders, scorpions, horseshoe crabs etc.) and myriapods, which include millipedes and centipedes. Up until now, genomic sequences had been generated from representatives of all of these subphyla except the hexapods. Now a new...

Myelin sheath is an important component of the nervous system because it aids in neuronal function and improves the efficiency of neuronal communication.  It is formed by oligodendrocytes, which wrap layers of cell membrane around neurons to provide insulation to neurons, increase conduction velocity and the speed of neuronal processing.  Myelinated neurons have whitish appearance and are therefore called white matter in the central...

Having power impacts fundamentally on the way a person speaks, to the extent that it can be perceived by a listener. This is the main finding of a new study in the journal Psychological Science, a journal of the Association for Psychological Science. The study comes from a research team in San Diego State University and Columbia University.

A study published in the current issue of the journal Nature Neuroscience offers hope for treating the cognitive learning/memory deficits attributable to Noonan Syndrome in both children and adults. The study is the result of the efforts of a team of international researchers, including lead author Yong-Seok Lee, and group leader Alcino Silva at the University of California Los Angeles.
