How nature itself uses genetic modification

Revealing how nature uses sunlight to split water. Introduction.

How mitosis keeps itself in order

How mitosis keeps itself in order C ells progress through mitosis by switching protein activities on and off in a clearly defi ned order. The ubiquitin ligase APC/C deactivates mitotic proteins by targeting them for degradation by the proteasome. The APC/C is activated by two different subunits that recognize short sequence motifs, known as D and KEN boxes, in the target proteins. In early mito...

Phishing: How an Organization can Protect Itself

The objective of this paper is to report on research to construct a model, which should provide guidance to an organization on how to address all dimensions associated with phishing and assist in solving the problem holistically. The emphasis will be placed on the human and organizational dimensions. Most research in this area has shown that only certain dimensions used to combat phishing attac...

Genetic modification and genetic determinism

In this article we examine four objections to the genetic modification of human beings: the freedom argument, the giftedness argument, the authenticity argument, and the uniqueness argument. We then demonstrate that each of these arguments against genetic modification assumes a strong version of genetic determinism. Since these strong deterministic assumptions are false, the arguments against g...

The computational nature of memory modification

Retrieving a memory can modify its influence on subsequent behavior. We develop a computational theory of memory modification, according to which modification of a memory trace occurs through classical associative learning, but which memory trace is eligible for modification depends on a structure learning mechanism that discovers the units of association by segmenting the stream of experience ...
