"Tracking, collecting and tabulating data from marine samples, satellite images and shipboard information is cumbersome, but with a new software interface the task becomes more manageable and improves the data's value, say marine biologists."
"Putting all of those pieces together took time and involved referring to numerous data sources, recalls Chris Scholin, the lead biologist on the project. Now the newly designed software interface makes it an "all-in-one stop" where information about the ship's movement can be plotted onto a map and displayed in a geographical information system (GIS) program, which can be overlaid with the latest satellite data regarding water temperature or clarity, for example. Additionally, biologists can enter any new molecular data right away, and compare it with previous samples in real time."

Efforts are also under way to identify the thousands--and potentially millions--of proteins encoded by those genes. Researchers are now pursuing the next logical step in integrating all this data: systems biology.
The goal is to understand not just the functions of individual genes, proteins and smaller molecules like hormones, but to learn how all of these molecules interact within, say, a cell. Biologists hope to then use this information to generate more accurate computer models that will help unravel the complexities of human physiology and the underlying mechanisms of disease. The biggest payoff: faster development of more-effective drugs."

HMS Beagle Are Computers Evolving in Biology?

"I suspect that although the new enthusiasm for computers in biology is genuine, it overlooks some basic problems in implementation. The basic difficulty, as I see it, is that although biologists use computers, they do not trust everything that comes out of them. It is one thing to use them to print up nice-looking graphs, but it is an entirely different matter to use them to think better."
"Francis Crick was once quoted as saying that no biologist had ever made a discovery using a mathematical model. I would reply that no biologist has ever made a discovery by running an electrophoretic gel. They make discoveries by using their brains. Computers, like all scientific tools, are only as good as the person who uses them. If biologists don't understand how computer models are constructed, they won't know their strengths and limitations. Without some foundation of trust, biologists will be unlikely to utilize or accept this powerful method of data analysis."

"The integration of bioinformatics with these systems approaches is an integral, essential feature. One of the things that we stress is that in the future it's going to be increasingly important for people in bioinformatics to be intimately associated with data producers, because no matter how smart you are you can't model biological complexity--it's just too complex. The only way we're going to understand it is through the integration of these global experimental observations, together with powerful computational tools for analysis, and ultimately, for modeling.
A mistake that a lot of people in bioinformatics have tended to make is thinking that you can set up a bioinformatics center and it can work in isolation from the biology, and it can study all these great databases and learn lots and lots about biology. In vitro biology and in silico biology are all popular terms, but it isn't true, and it isn't going to be true in the future."

Moreover, while much of molecular biology has involved studying a single gene or protein in depth, systems biology looks at the bigger picture, how all the genes and proteins interact. Ultimately the goal is to develop computer models that can predict the behavior of cells or organisms, much as Boeing can simulate how a plane will fly before it is built.
But such a task requires biologists to team up with computer scientists, engineers, physicists and mathematicians. The structure of universities makes that difficult, Dr. Hood said."

Nature Segmentation in silico
"A new mathematical biology is emerging. Building on experimental data from developing organisms, it uses the power of computational methods to explore the properties of real gene networks."
"Our understanding of gene networks is at an early stage. We perceive their complexity only after it has been filtered by the limitations of the techniques used to study them. Genome databases and DNA-chip technology, which enables huge numbers of genes to be screened for activity, will undoubtedly provide more, and much more complicated, data than anything produced by Drosophila genetics. If a relatively simple gene network such as the segment-polarity system is hard to understand intuitively, we can be certain that modelling will be essential to make sense of the flood of new data.
But this will not be elegant theoretical modelling: rather, it will be rooted in the arbitrary complexity of evolved organisms. The task will require a breed of biologist-mathematician as familiar with handling differential equations as with the limitations of messy experimental data. There will be plenty of vacancies, and, on present showing, not many qualified applicants."

Genomics and all its related buzzwords have been responsible for much of the media attention, government grants, and investment capital heaped on the biotech industry over the past decade.
But just as there is a whole lot of chemistry that happens in between the periodic table and a birthday cake, there is a lot of biology in between the genome and a living organism. With the completion of biology's periodic table within sight, academics and industry players alike are pondering the best way to apply our hard won knowledge.
The only problem is, the path from genome to system seems to get harder the more we learn."

Harnessing all that computing horsepower--more than one petaflop, or 1,000 trillion floating-point calculations per second--would, it was hoped, allow scientists to simulate the folding of a protein, an extraordinarily demanding task which might help to streamline the discovery of new drugs.

The Economist Publish and perish?
"THE rapid progress of genomics means that the publication of yet another gene sequence for one of the Earth's many millions of species is not guaranteed to raise much interest. But this is no ordinary species. Bacillus anthracis is the bug that causes anthrax. The publication, in Nature, comes two months after a group of editors of the world's leading scientific journals announced they were worried about publishing information that could be used by terrorists to evil ends. New procedures had therefore been put into place to tackle this threat. The question is, do they work?"

BBC Bioterror fears impact free science
"A group of leading scientific journals has announced measures aimed at restricting the publication of research which could be used by bioterrorists.
In a joint statement, the journals' editors say it is crucial that concerns over terrorism do not affect the release of valuable medical research.
But they say they recognise there may be occasions when new research data should be withheld from publication because it could be abused.

Genomeweb Should Bioterror Fear Make Sequences Secret? For TIGR's Fraser It's a Qualified No
"Despite fears that bioterrorists will use DNA sequence data to create 21st century superpathogens, genomic science should remain public, The Institute for Genomic Research head Claire Fraser said at a special National Academies meeting on national security and the life sciences last week.
Her explanation: genomics just isn't good enough yet to provide the kind of tools terrorists need."

"Scientific information that the US government wants to keep mum, but which can't officially be labeled "classified," has been designated "sensitive but unclassified." One example is the National Academy of Science's recent report on agricultural bioterrorism. Its chapter on bioterror case studies is available only on a need-to-know basis. Other professional groups may find themselves in the same boat, but the rules governing the category are anything but clear.

“Bioinformatics will be at the core of biology in the 21st century. In fields ranging from structural biology to genomics to biomedical imaging, ready access to data and analytical tools are fundamentally changing the way investigators in the life sciences conduct research and approach problems. Complex, computationally intensive biological problems are now being addressed and promise to significantly advance our understanding of biology and medicine. No biological discipline will be unaffected by these technological breakthroughs.”
