    One of the greatest scientific discoveries of the twentieth century is the structure of DNA and how it encodes proteins. Current genome projects, especially the Human Genome Project, have sparked interest in the information encoded in DNA, which is often referred to as "the blueprint for life", implying that it contains all the information needed to create life. This interpretation ignores the com... View full abstract»

    Systematists study how a group of genes or organisms evolved. These biologists now have set their sights on the Tree of Life challenge: to reconstruct the evolutionary history of all known living organisms. A typical phylogenetic reconstruction starts with biomolecular data, such as DNA sequences for modern organisms, and builds a tree, or phylogeny, for these sequences that represents a hypothesi...

    Technology frequently turns out to be a double-edged sword. For example, as technology has increased connectivity and network accessibility, concerns about privacy and security have grown. As this concern has increased, invasive technologies-such as those that let third parties plant software on a PC and monitor users' activities from across a LAN or the Internet-are becoming more sophisticated. T... View full abstract»

    The authors propose a new software system that incorporates biological data and domain-specific knowledge and show how biologists can use it to model, analyze, and experiment with genomic evolutionary processes. A better understanding of biology will come through information-theoretic studies of genomes that provide insights into DNA's role in governing metabolic and regulatory pathways. Understan...

    Embedded processors are fundamentally different from desktop processors -costs are too tight for fancy chip sets and expensive packaging. So if you're new to embedded processors, the marketplace is foreign. Worse, so are the design decisions. When you consider purchasing an embedded microprocessor, look carefully at the direct memory access engine View full abstract»

    The computing profession has had many great successes, but there have been many great blunders. Blunders arise from a failure of imagination, from an inability to see beyond the immediate problem to its full social or professional context. If professionals acquire an education in and remain sensitive to social and ethical issues, they will commit fewer blunders and recover more swiftly from them. ... View full abstract»

    Fusing computing and biology expertise, bioinformatics software provides a powerful tool for organizing and mining the vast amounts of data genetics researchers are accumulating. As life scientists and computational scientists interact to create useful bioinformatics software systems, several themes or lessons recur. We identify seven themes: the nature of biological data; data storage, analysis a... View full abstract»

    Using genomic information to understand complex organisms requires comprehensive knowledge of the dynamics of phenotype generation and maintenance. A phenotype results from selective expression of the genome, creating a history of the cell and its response to the extracellular environment. Defining cell phenomes requires tracking the kinetics and quantities of multiple constituent proteins, their ... View full abstract»

    Biology and computer science share a natural affinity. Physicist Erwin Schrodinger envisioned life as an aperiodic crystal, observing that the organizing structure of life is neither completely regular, like a pure crystal, nor completely chaotic and without structure, like dust in the wind. Perhaps this is why biological information has never satisfactorily yielded to classical mathematical analy... View full abstract»

    Ultimately, genome sequencing seeks to provide an organism's complete DNA sequence. Automation of DNA sequencing allowed scientists to decode entire genomes and gave birth to genomics, the analytic and comparative study of genomes. Although genomes can include billions of nucleotides, the chemical reactions researchers use to decode the DNA are accurate for only about 600 to 700 nucleotides at a t... View full abstract»
