Swallows track human moves
Most studies of the impact of humans on other species tend to be negative as more and more habitats are destroyed or degraded, so a new study provides a surprising contrast. It adds weight to the view that one of the northern hemisphere's best-loved summer visitors has vastly increased in range and numbers as a result of human activity. The barn swallow is found across North America, Europe and...
متن کاملMolecular Devices AUnidirectional DNAWalker That Moves Autonomously along a Track**
Amajor challenge in nanotechnology is to precisely transport a nanoscale object from one location on a nanostructure to another location along a designated path. The successful construction of self-assembled DNA nanostructures provides a solid structural foundation to meet this challenge. DNA, with its immense information-encoding capacity and welldefinedWaston–Crick complementarity, has been e...
متن کاملSimulating Human Tutor Dialog Moves in AutoTutor
This purpose of this paper is to show how prevalent features of successful human tutoring interactions can be integrated into a pedagogical agent, AutoTutor. AutoTutor is a fully automated computer tutor that responds to learner input by simulating the dialog moves of effective, normal human tutors. AutoTutor’s delivery of dialog moves is organized within a 5step framework that is unique to nor...
متن کاملHuman genetics: Methylation moves into medicine
The role of DNA methylation in mammalian development has been a source of controversy for some time. Methylation of DNA, which takes place on the cytosine of CpG dinucleotides, is clearly required for development, because mice lacking the maintenance methyltransferase gene Dnmt1 die early in development [1]. It is also generally agreed that the primary role of DNA methylation is to silence tran...
