BITE MARKS ON THE FRILL OF A JUVENILE CENTROSAURUS FROM THE LATE CRETACEOUS DINOSAUR PROVINCIAL PARK FORMATION, ALBERTA, CANADA

Bite marks on the frill of a juvenile Centrosaurus from the Late Cretaceous Dinosaur Provincial Park Formation, Alberta, Canada

Bite marks on bones can provide critical information about interactions between carnivores and animals they consumed (or attempted to) in the fossil record.Data from such interactions is somewhat sparse and is hampered by a lack of records in the scientific literature.Here, we present a rare instance of feeding traces on RAW CACAO NIBS the frill of

Resistance Monitoring for Six Insecticides in Vegetable Field-Collected Populations of Spodoptera litura from China

The common cutworm, Spodoptera litura (Fabricius), is a notorious and damaging insect pest of horticultural crops in China, the management of which largely relies on chemical agents that are limited by the development of chemical resistance in target populations.As such, resistance monitoring of S.litura populations is a necessary part of managemen

Systematic dissection and trajectory-scanning mutagenesis of the molecular interface that ensures specificity of two-component signaling pathways.

Two-component signal transduction systems enable bacteria to sense and respond to a wide range of environmental stimuli.Sensor histidine kinases transmit signals to their cognate response regulators via phosphorylation.The faithful transmission of information through two-component pathways and the avoidance of unwanted cross-talk require exquisite
