The precise number and pattern of axonal connections generated during brain development regulates animal behavior.Therefore, understanding how developmental signals interact to regulate axonal extension and retraction to achieve precise neuronal connectivity is a fundamental goal of neurobiology.We investigated this question in the developing adult
Diet and subsistence in Bronze Age pastoral communities from the southern Russian steppes and the North Caucasus.
The flanks of the Caucasus Mountains and the steppe landscape to their north offered highly productive grasslands for Bronze Age herders and their flocks of sheep, goat, and cattle.While the archaeological evidence points to a largely pastoral lifestyle, knowledge regarding the general composition of human diets and their variation across landscape
Low-cost wave characterization modules for oil spill response
Marine oil spills can be remediated by mechanical skimmers in calm waters, but performance degrades with increased wave height.We have developed and demonstrated a system that quantifies local wave characteristics with an uncertainty of four inches of heave.Our system is intended for the measurement of wave characteristics during oil Two Drawer Mob
The unusual practices within some Neo-Pentecostal churches in South Africa: Reflections and recommendations
This article reflects and makes recommendations on the recent unusual practices within some Neo-Pentecostal churches in South Africa.Neo-Pentecostal churches in South Africa refer to churches that have crossed denominational boundaries.These churches idolise the miraculous, healing, deliverance and enactment of bizarre church performances often per
Oviposition stimulants underlying different preferences between host races in the leaf-mining moth Acrocercops transecta (Lepidoptera: Gracillariidae)
Abstract The importance of plant chemistry in the host specialization of phytophagous insects has been emphasized.However, only a few chemicals associated with host shifting have been characterized.Herein, we focus on the leaf-mining moth Acrocercops transecta (Gracillariidae) consisting of ancestral Juglans (Juglandaceae)- and derived Lyonia (Eric
