The genus Spasskia Belokobylskij, 1989 (Hymenoptera: Braconidae: Helconinae) is reported for the first time from China. Two species, namely Spasskia brevicarinata Yan et Chen sp. n.and Spasskia indica Singh, Belokobylskij et Chauhan, 2005 are described and illustrated. A key to the species of this genus is updated to include the new species.

In this issue, two papers implicate histone H3 lysine 56 acetylation in histone deposition in chromatin. Li et al. (2008) show that acetylation of H3K56 promotes S phase chromatin assembly that is mediated by the histone chaperones CAF-1 and Rtt106. Chen et al. (2008) establish that the acetylation mark promotes chromatin reassembly following DNA double-strand break repair.

An annotated list of the species genus Interphasma Chen et He, 2008 from China is given. huayingshanense Li, Shi Wang, sp. n. described Chinese province Sichuan. The type specimens a new are deposited in collection Department Plant Protection, College Agronomy, Sichuan Agricultural University.

In this issue of Blood, Chen et al and Kameda et al demonstrate that Tet2 loss has 2 effects in Jak2V617F mice: it increases both the severity of the myeloproliferative disorders and the self-renewal properties of the Jak2V617F hematopoietic stem cells (HSCs).

Paternal diet influences offspring metabolism, yet the underlying epigenetic mechanisms are unclear. Recently, Chen et al. (2016) and Sharma et al. (2016) identified tRNA fragments in sperm and the male reproductive tract as possible inherited factors altered by paternal diet that lead to gene misexpression and altered metabolism in offspring.

In this issue of Neuron, Chen et al. (2012) and van Versendaal et al. (2012) used fluorescently tagged gephyrin to track inhibitory synapses in the mouse visual cortex in vivo. Their studies show that visual experience-dependent plasticity is associated with clustered and location-specific pruning of inhibitory synapses.

Thaiscelis alutaceus gen. et sp. nov. is described from Thailand, which is the first record of the subfamily Caliscelinae from this country. The taxonomic position of the genus Bambusicaliscelis Chen et Zhang, as well as the evolution of the family Caliscelidae, are briefly discussed. The area of origin and the primitive and advanced groups of the family are hypothesized.

In wireless sensor networks (WSNs), a registered user can login to the network and use a user authentication protocol to access data collected from the sensor nodes. Since WSNs are typically deployed in unattended environments and sensor nodes have limited resources, many researchers have made considerable efforts to design a secure and efficient user authentication process. Recently, Chen et a...
