Cell fusion and nuclear fusion in plants
Seminars in Cell & Developmental Biology, 2016Eukaryotic cells are surrounded by a plasma membrane and have a large nucleus containing the genomic DNA, which is enclosed by a nuclear envelope consisting of the outer and inner nuclear membranes. Although these membranes maintain the identity of cells, they sometimes fuse to each other, such as to produce a zygote during sexual reproduction or to ...

The Role of Controls in Nuclear Fusion
Proceedings of the 45th IEEE Conference on Decision and Control, 2006The need for new sources of energy is expected to become a critical problem within the next few decades. Although controlled fusion is a very challenging technology, a fusion power reactor would offer significant advantages over existing energy sources, including no air pollution or greenhouse gases, no risk of nuclear accident, no generation of ...

Nature, 1966
THE idea that chromosomes can double repeatedly by “internal growth” without mitosis was put forward by G. Hertwig1 and others to account for the giant (polytene) chromosomes in the salivary glands of Diptera. Berger2 showed that in larvae of Culex (2n=6) the epithelial nuclei of the ileum undergo a succession of such internal divisions with a ...

Reviews of Modern Physics, 1999
The earliest speculations about nuclear power—first, about nuclear fusion— followed soon after the publication of Albert Einstein’s special theory of relativity. A story related by Edward Teller tells of the young George Gamow’s being offered, in 1929, the nightly use of the full electric power grid of Leningrad if he would undertake to create in the ...

Physics of Atomic Nuclei, 2012
Recent accelerator experiments on fusion of various elements have clearly demonstrated that the effective cross-sections of these reactions depend on what material the target particle is placed in. In these experiments, there was a significant increase in the probability of interaction when target nuclei are imbedded in a conducting crystal or are a ...

During the five years I spent at ITER I discovered that people visiting ITER, despite very different origins and backgrounds, have one thing in common: the vast majority of them confuse nuclear fission and nuclear fusion. However, the difference between fusion and fission is indeed fundamental. In modern nuclear fission power plants large atomic nuclei
