Gates fields questions from future competitors at MIT
"Software is the engine that makes the IT industry run, and developers will need to adapt as the world of computer science changes over the next several years, said Bill Gates, chief software architect at Microsoft Corp., in a speech to students at the Massachusetts Institute of Technology (MIT) Thursday."
"A student asked Gates what fields he would consider if he were a computer science student today. After drawing laughs for alluding to his decision to drop out of neighboring Harvard University to found Microsoft with Paul Allen, Gates cited artificial intelligence and computational biology as two areas that he would like to study if he were a student again."

The Dawn of
McScience
"In Science in the Private Interest , a strongly argued polemic against the commercial conditions in which scientific research currently operates, he shows how universities have become little more than instruments of wealth. This shift in the mission of academia, Krimsky claims, works against the public interest. Universities have sacrificed their larger social responsibilities to accommodate a new purpose--the privatization of knowledge--by engaging in multimillion-dollar contracts with industries that demand the rights to negotiate licenses from any subsequent discovery (as Novartis did, Krimsky reports, in a $25 million deal with the University of California at Berkeley). Science has long been ripe for industrial colonization. The traditional norms of disinterested inquiry and free expression of opinion have been given up in order to harvest new and much-needed revenues."
redux [01.16.02]
"A debate is heating up in the academic community over whether software that is generated by publicly funded research must be released with an open source license. The Internet is one example of how releasing research code benefited the public, but the trend seems to be changing now, and universities are more likely to consider the profit opportunity. The Bayh-Dole Act paved the way for the privatization of publicly funded resources, but not everyone is happy with the results.
Against the tide of privatization comes a group of bioinformatics researchers and programmers with an online petition to require that all software created by publicly funded research projects be licensed as open source. They have founded a group and a Web site, OpenInformatics.org, to further this cause.
Here we present two opposing viewpoints on this issue."

"ONCE upon a time, pure and applied science were the same. Sir Humphry Davy discovered seven chemical elements, and invented the miner's safety lamp. Louis Pasteur investigated the properties of molecules, and worked out how to stop milk spoiling. Everybody thought that was admirable. Somehow, things have changed. Today the feeling is widespread that science and commerce should not - must not - mix. There is a queasy suspicion that the process of discovery is in some way corrupted if it is driven by profit."
"Far from compromising science, profit in both these cases - the development of new medicines and the elucidation of the genome - has animated it, and directed it towards meeting pressing human needs. It is a happy marriage. Davy and Pasteur would surely have approved."

Xerox Unveils New Document-Management Technology
"Scientists at Xerox's Research Centre Europe in Grenoble, France, said Thursday that they've come up with new classification software clever enough to "read" an electronic document, decide how it should be classified, then automatically route it to the right person's E-mail address or an online document-management system."
"In the pilot program that Xerox ran with the Swiss Institute of Bioinformatics, an academic nonprofit foundation, "their traditional search engines for medical articles often presented the most pertinent documents at the end of the list," said Gaussier. "Using our software, they were much more successful at finding what they were looking for, and typically had to browse less than half of the list to find the information.""

Farming pharma
"Indian pharmas are also waking up to the fact that 'ripping off' patented drugs is becoming more difficult with 'legit piracy' no longer a real option. It's in this changed scene that India plans to make a splash.
A well-developed base industry such as pharma gives India a distinct advantage over others in the biotech boom. It already has a good network of research labs and scores of bioinformatic units have been set up by IT companies across the country. Add to these a rich biodiversity and access to diverse disease populations, and India is ready to ride the wave. At the forefront of this 'petri-dish revolution' will be drug companies -- especially those that manage to add bioinformatics to the already existing arsenal of molecule'n'mortar process."
redux [02.11.04]
"Software major Sun Microsystems would set up a Centre of Excellence (CoE) for medical bio-informatics at Centre for DNA Fingerprinting Analysis and Development (CDFD) here. The CoE would help in analysis, storage of biological research in areas like genomics, structural biology and molecular evolutionary genetics."
"The proposed CoE is the ninth major medical bio-informatics centre established by Sun in the world and first in India."

"Tata Consultancy Services (TCS) is on track to launch it's biotech software package 'Bio-Suite' by April '04. The software, which will be used in analysing and accelerating drug discovery processes, is being developed in partnership with the Council for Scientific and Industrial Research (CSIR)."
"The software consists of eight 'blocks' covering all aspects of computational biology ranging from genomics to structure-based drug design. In all, Bio-Suite encompasses more than 200 individual algorithms, and is designed to be highly modular so that new algorithms can be added as scientific advances take place."
redux [08.07.03]
"Sun Microsystems has made a proposal to the department of biotechnology to invest in bioinformatics projects in India and to collaborate with various R&D institutions under the department in this burgeoning area. DBT's Task Force on bioinformatics has asked to multinational to specify the quantum of investment and the specific areas of bioinformatics wherein alliances could be forged with Indian institutes."
Official sources said that the Centre for DNA Fingerprinting & Diagnostics, Hyderabad which has an alliance with software services major Tata Consultancy Services, would possibly be a nodal centre for the joint venture project with Sun."
redux [07.14.03]
"The report estimates that currently up to 10 per cent of investment in R&D is IT-related, and hence there is huge potential for Indian biotech and IT companies to enter into collaborative bioinformatics research with global pharma majors in the near term.
The report, however, indicated that despite India's IT capabilities, it may be difficuly to replicate this success in biotechnology as biotechnology differs from IT in many ways. Avendus suggests that Indian players will have to leverage upon the lower costs of infrastructure and human resources. The cost of setting up and running a bioinformatics company in India is a fraction of the cost in the US."
redux [03.18.03]
"Despite several strengths inherent, India's biotechnology industry is not able to take a quantum jump mainly due to lack of capital and low R&D spending, absence of industry-academic partnership and the mismatch between strategic research, product planning and effective collaboration.
The Associated Chambers of Commerce and Industry of India (Assocham) paper on Business of Biotechnology has pointed out that India has several options with the main focus on informatics. Bioinformatics is crucial for the advancement of the biotech industry by cutting the timeframe and costs in developing a product tremendously."
"Everyone in the room, from Sen. Hillary Rodham Clinton to Buffalo Mayor Anthony Masiello, was beaming at last week's announcement.
The news was that Asia's largest computer consultant has become a deep-pocket partner of the University at Buffalo. Under an agreement signed Monday, Tata Consultancy Services of India will partner with local researchers and help transform their discoveries into money-making products."
"But some in the tech community voiced concern that the state's $100 million-plus bioinformatics investment will wind up boosting the economy in Bombay instead of Buffalo."

"India is set to reap substantial rewards in the field of functional genomics, thanks to an invaluable genetic resource and highly advanced IT expertise, predicts Samir Brahmachari, director of the country's Institute of Genomics and Integrative Biology in Delhi."
"Brahmachari sees India's genetic resource - not the biological samples themselves, but the associated information - as a tradable commodity. Data can be processed using India's unparalleled IT expertise, he says: The country's IT industry generated about $10 billion in revenues this year, and has continued to grow by 50% each year over the past decade. The information, once processed, represents an "intellectual-property protectable" commodity, he says."
redux [06.23.02]
"Also, India's success in information technology provides excellent opportunities in the field of bioinformatics.
"Traditional IT companies are translating their strong capabilities in data mining and warehousing to business models based on biological data," says the report, citing examples of IBM's India Research Lab and Satyam's five-year agreement with the Center for Cellular and Molecular Biology, Hyderabad."
redux [02.13.02]
"India's biotech boom could even dwarf software in coming years if you trust the most optimistic projections. Much of our $2.5-billion biotech market relies on low-end products like vaccines, but experts predict that as more start-ups come up, that could change dramatically."
"The need to dive into this ocean of genetic data for hidden treasures has created a whole new discipline--bio-informatics, the science of using information technology (IT) to decipher the genomic jumble. Thanks to a flourishing IT industry, bioinformatics is today the darling of venture capitalists, drug firms, and, of course, IT majors. So, Satyam Computers has signed a five-year alliance with CCMB to create, store, and annotate genetic databases, and it is angling for contracts from global bigpharma to sequence genes and build protein catalogs. Strand Genomics, a Bangalore-based bio-informatics start-up, is designing tools to accelerate drug discovery."
redux [09.17.01]
"India has the potential to garner 8-10 per cent of the global software market in the next few years from the current levels of just 1.5 per cent, but the country?s planners need to focus on improving computer penetration and use of Indian made software in the industry.
This was the view of FC Kohli, chairman, Tata Consultancy Services, while speaking at Connect 2001, an international conference and exhibition on information technology, communication technologies and bioinformatics, which opened on Thursday. Currently, India's IT exports are about $8.7 billion."
redux [08.27.01]
"THE mood is one of caution as far as bioinformatics is concerned. The beginning of the year saw hype building up around the fledgling industry as the next big gold rush for India.
But six months after the first bioinformatics seminar in the country, with the IT industry's lesson on hype fresh in mind, things are moving at a more sedate pace."
"In India, bioinformatics training institutes have already begun to mushroom. Bangalore and Hyderabad have around five private training institutes between them. However, the industry is sceptical about the quality of manpower these centres can supply because most of them have short-term courses offering basic skills, says Dr. Sabharwal. In all fairness to them she adds, "We need to wait for a few months to see the outcome of it all.""

The dark side of the moon is a misnomer. Light reaches la luna's entire surface, but one half is unviewable from Earth. The human genome, the now essentially decoded map of life, likewise has a light side--the genes encoding mRNA and protein--and a dark side, which is coming into view for the first time. The dark side encompasses more than its opposite: The majority of the genome comprises intronic regions, stretches of repeat sequence, and other assorted gibberish that has attained the ignoble dubbing, "junk."
The first exploratory missions to the human genome's faceted surface are turning up traces regarding the extent of the junk."
redux [11.21.02]
"In a provisional patent application filed July 31, Pellionisz claims to have unlocked a key to the hidden role junk DNA plays in growth -- and in life itself.
Rather than being useless evolutionary debris, he says, the mysteriously repetitive but not identical strands of genetic material are in reality building instructions organized in a special type of pattern known as a fractal. It's this pattern of fractal instructions, he says, that tells genes what they must do in order to form living tissue, everything from the wings of a fly to the entire body of a full-grown human."

"In a new study in the August 29 issue of Nature, researchers at The Wistar Institute identify a cohesin-containing protein complex that reshapes chromatin to allow cohesins to bind to DNA. In doing so, they also identified the locations on the human genome where the cohesins bind. Somewhat to their surprise, the binding sites were found to be a repetitive DNA sequence found throughout the human genome for which no previous role had ever been identified. These bits of DNA, known as Alu sequences, are liberally represented along those vast stretches of the human genome not known to directly control genetic activity, sometimes referred to as junk DNA."
redux [08.09.02]
"Results of a new University of Michigan study suggest that junk DNA - dismissed by many scientists as mere strings of meaningless genetic code - could have a darker side.
In a paper published in the Aug. 9 issue of Cell, scientists from the U-M Medical School report that, in cultured human cancer cells, segments of junk DNA called LINE-1 elements can delete DNA when they jump to a new location - possibly knocking out genes or creating devastating mutations in the process."
"Scientists in the past decade have discovered that remnants of ancient germ line infections called human endogenous retroviruses make up a substantial part of the human genome. Once thought to be merely "junk" DNA and inactive, many of these elements, in fact, perform functions in human cells.
Now, a new study by John McDonald of the University of Georgia and King Jordan at the National Center for Biotechnology Information at the National Institutes of Health, suggests for the first time that a burst of transpositional activity occurred at the same time humans and chimps are believed to have diverged from a common ancestor - 6 million years ago."

The first, Collins said, will be a paper that puts the total count of human genes at between 30,000 and 35,000. "That's less than half the number most people have been predicting.'' The second is a study ascribing previously unknown biological missions to genes scientists thought were inactive, or so-called "junk genes."

IBM plans second Blue Gene supercomputer
"IBM will install a second Blue Gene/L supercomputer as part of a radio telescope project in the Netherlands, the company plans to announce Monday.
The supercomputer will be used for a new radio telescope project called Lofar, short for low frequency array, run by a Dutch organization called Astron. The system, which is expected to be complete in 2005, will run the Linux operating system, use about 12,000 processors and perform more than 30 trillion calculations per second, sources familiar with the plan said."
redux [11.15.03]
"IBM on Friday talked up its Blue Gene/L supercomputer, the first module of which is a relatively small, dishwasher-size machine that can perform 1.4 trillion calculations per second.
The performance is enough to make the machine the world's 73rd fastest supercomputer, according to a ranking of the top 500 to be released Sunday. By the time IBM has upgraded the box's 512 chips, each with two processors, and linked it with another 127 identical systems in 2005, Big Blue hopes to take the top spot."
redux [09.19.03]
"WHATEVER happened to Blue Gene, IBM's ambitious attempt to build the world's fastest computer? The project, launched in 1999, called for the construction of a "massively parallel" computer with over 36,000 processing chips, each containing 32 processing cores roughly equivalent in power to a desktop PC. 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 idea was to achieve all of this within five years--something that even enthusiasts thought ambitious.
Four years on, the chips that will power the first Blue Gene computer are now being manufactured and tested. But the plans have changed somewhat."
redux [05.08.03]
""Blue Gene is a completely oddball, you've-never-seen-anything-like-this-before design," said Illuminata analyst Jonathan Eunice. "It is not custom everything, (but) it is still very exotic compared to anything you can buy.""
"IBM already has spent more than the original $100 million budgeted for the project and won't meet its 2004 goal for the ultimate machine, but the company has made progress bringing its ideas to fruition."
redux [02.11.03]
"THE first version of IBM's revolutionary Blue Gene chip will roll off the production line this quarter, Ajay Royyuru, head of IBM's Computational Biology Centre, has revealed."
""We plan to build a 512-node prototype Blue Gene machine in our Watson Research Centre, in New York, where I am located, hopefully before the end of the year.
Then we will build a 64,000- node Blue Gene machine and deliver it to the Lawrence Livermore laboratory by late 2004, or early 2005."
redux [10.24.02]
"Linux will be the main operating system for IBM's upcoming family of "Blue Gene" supercomputers--a major endorsement for the OS and the open-source computing model it represents."
""We had two choices of operating systems for the Blue Gene family, either use a special purpose system or Linux," Bill Pulleyblank, director of Exploratory Server Systems at IBM Research, said in a statement. "We chose Linux because it's open and because we believed it could be extended to run a computer the size of Blue Gene. We saw considerable advantage in using an operating system supported by the open-source community so that we can get their input and feedback.""
redux [07.13.01]
""Ambuj Goyal, IBM Research's general manager for software, solutions, and strategy, was more ambitious than that. Why not build a machine to model molecular dynamics using general-purpose chips rather than specialized ones? That way you'd produce a prototype for a whole new family of supercomputers. Not only would it be great technology development, it would be great marketing, too. Whereas the Department of Energy has the greatest interest in top-end supercomputing - with its need to understand how nuclear weapons work - focusing on the life sciences rather than the death sciences could make supercomputing more widely appealing. What's more, a biology program would be a way of telling one of the newest markets for big iron - the post-genome biotech world - that IBM took its interests seriously. "We believe that the life sciences are going to be a rapidly growing area," says Blue Gene project manager Bill Pulleyblank, "a huge growth area for IBM.""

Celera
defends human sequence
""We hope it puts to rest, once and for all, all this whining that's been going on that the genome could not be assembled without the public data," J. Craig Venter, founder of Celera Genomics and coauthor of the paper, told The Scientist ."
"Bob Waterston, professor and head of the Department of Genetics at the Genome Sequencing Center, University of Washington School of Medicine, one of the leading critics of the Celera data, was not impressed."
redux [02.10.04]
"In a paper published in the Proceedings of the National Academy of Sciences, Celera Genomics has vowed to deposit the draft human genome sequence it published in 2001, as well as two more recent human genome assemblies, in GenBank.
The company also pledged to release the source code for its Celera Assembler genome assembly algorithm."
"Their report, to be published online in the Proceedings of the National Academy of Sciences, compares the accuracy of the draft sequences against the "finished" human genome sequence now available at GenBank.
According to the report, both versions "covered about the same amount of the genome, but they did so in different ways." The Celera sequence provided "more order and orientation" while the HGP sequence provided "better coverage of exact and nearly exact repeats.""
redux [06.13.02]
"But Celera's rival published its version free of charge on the internet, a move which damaged Celera's commercial prospects. "That has had an impact," says Bennett. "Any stand-alone information business will be challenged because the value of information degrades," he adds.
But he denies that the venture has been a failure. "We have 250 subscribers, both commercial and non-commercial," says Bennett. The business even makes a profit, but the company will not discuss the impact of the free genome data on profits."
redux [01.28.02]
"As all that was happening, people who know him say, White, Venter's boss, was getting grumpy. He well knew that Celera, under its original business plan, could not deliver long-range earnings growth that would justify what the market was paying for Celera shares. One top genetic scientist said White snapped to him in the midst of the publicity barrage, "'This is all nice, but we need a business plan.'"
They quickly came to the same conclusion as many minds before them: In biology and medicine, the only business plan that offers the potential of extraordinary profits is drug development. All the biotechnology superstars have been companies with hit drugs."
redux [01.22.01]
"Dr Craig Venter, the US scientist who led the private effort to decode the human genome, has quit as boss of his company Celera Genomics."
""We are now at a critical juncture where my best contributions can be made in a scientific advisory role, allowing the rest of the organisation to continue Celera's progress toward becoming a successful pharmaceutical business.""
redux [06.09.00]
"Great discoveries do not necessarily make great businesses. Businesses have to sell something. Celera Genomics doesn't sell or make anything tangible. It hawks service and information. It sells access to lists of genes and computers that can sort through those messy lists. Samuel Broder, the company's executive vice president and chief medical officer, makes Celera sound like some kind of consulting company, or perhaps a library."
"Venter's quest could be a fable, with all sorts of morals about the power of capitalism and the importance of a single, brilliant, willful individual who used the market to shake the ivory towers of science. But those morals only hold if Celera succeeds, if business and science blend to propel the company into the future with breathtaking speed without rocketing it into the realities of the marketplace. Celera could become one of the great business success stories. It could also be a financial train wreck."
Right now, that makes it a very volatile stock."
redux [07.17.00]
"Craig Venter, head of Celera Genomics which last month completed the map of the human genome, has outlined his next goal.
Speaking at a conference he said his new task was to map the proteins which drive all chemical reactions in the body."
""A big part of the business is the straightforward providing of information, but I'm not complacent just to do that," Venter said."

New technology aids cell analysis
"Equipped with cutting-edge techniques to track the activity of tens of thousands of genes in a single experiment, biologists now face a new challenge -- determining how to analyze this tidal wave of data. Stanford Associate Professor of Computer Science Daphne Koller and her colleagues have come to the rescue with a strategic approach that reduces the trial-and-error aspect of genetic sequence analysis.

The big picture
"Now, quite suddenly, biology is being consumed by a fast-moving intellectual revolution that could profoundly change the course of science -- and medicine -- in the new century. Called "systems biology," it is an audacious attempt to transcend molecular biology and understand organisms as complex interacting systems that are more than the sum of their parts -- that the best way to understand ants, for instance, is to study colonies rather than just the individual insects.
In only a few years, the idea has gone from fringe concept to rallying cry as Harvard, MIT and universities around the world scramble to establish large new systems biology efforts."
redux [02.04.04]
"Big Pharma is going to be a dinosaur. I think the whole industry is going to be restructured and they'll never be able to get systems biology, so they'll be out of the discovery business. Big Pharma is the worst of silos, even worse than medical schools.
Maybe there are a few like Amgen that'll be flexible enough to really change things. But even there, Roger Perlmutter [executive VP, R&D, Amgen], he's chairman of our board and he still doesn't get systems biology - and he's a really smart guy! See, these guys are too embedded in a billion-dollar-a-year drug [philosophy]. That's exactly the wrong attitude."
redux [01.14.04]
"But is big pharma up to the task of using systems biology to transform drug discovery? In spite of efforts like the one at Novartis to create breeding grounds for systems biology, some say that traditional pharmaceutical companies lack the organizational flexibility to make it work. Industry observers say big pharma may be able to integrate data from various biological experiments, or extract patterns from genomic data, but they doubt that systems biology will flourish there. That's because the ultimate goal of systems biology - constructing models of complex biological systems that would enable researchers to predict the outcome of particular experiments - may be beyond the ken of the highly structured behemoths."
"Even with the plethora of existing biological data, Sorger contends that biology is data-poor in "systematically acquired sets of data. All the interesting data in what I work in seems to be missing," he said. "We need to be able to link unstructured data in a systematic way."
"The barrier here is going to be crossed by creativity, not more CPUs," Sorger continued. "The goal is to usher in a systems biology approach without losing the small science that has sustained" the field."
redux [11.01.03]
"Dealing with the immediate challenge requires a shift to what researchers are calling systems biology, an emerging field of math-based predictive biology."
""I'm up to my eyes in targets," said Ken Kupfer, head of scientific informatics at Bayer's office in Berkeley, Calif. "The time it takes us to develop the depth of understanding we need blows our business models.""
redux [09.22.03]
"In a further validation of Big Pharma's acceptance of systems biology, GlaxoSmithKline has licensed part of the Ingenuity Pathways Knowledge Base to facilitate genome-wide computational analysis of biological systems underlying disease."
"According to Frank Mara, Ingenuity's senior vice president of marketing, "GSK will be using the Ingenuity Knowledge Base to internally build systems biology applications. Every biotech group out there should pay attention when GSK licenses this thing.""
"But major challenges remain in the area of systems biology, Hood said. On the academic level, where centers for systems biology and integrative biology are being established, the biggest challenge, according to Hood, is integration. "How do you create a cross disciplinary faculty?," he asked. "How do you put together the high-throughput technology? How do you deal with salary scales of software engineers and engineers so you doint get funneled off to industry?"
And then, while the centers themselves have received abundant funding, there is the issue of how to fund the research. A major challenge remains in getting the funding agencies, especially at the level of study sections, to understand that systems biology is more than "a big fishing expedition.," Hood said. "But we are pushing to get that.""
redux [09.05.03]
"With sights set on provoking the next wave of bio developments, schools including Cornell, Duke, MIT, Princeton, Stanford, the University of California, and the University of Michigan have undertaken bold initiatives to foster cross-fertilization among faculty and students of diverse disciplines. With state-of-the-art labs and mod monikers such as Bio-X and QB3, the programs will push scientists to seek interdepartmental solutions to biological questions raised by, among other things, genome data. And their directors - scientists who've had illustrious careers in biology, computational genomics, engineering, genetics, and medicine - are systems biology's new vanguard."
"As David Botstein, director of Princeton's fledgling Lewis-Sigler Institute for Integrative Genomics, notes, "We're in very early days. What we have here is high concept." But if concepts become reality, the training, research, and technologies that flow from these centers will instruct the future of the field that's becoming commonly known as systems biology."
redux [08.21.03]
"Some time last year, the "gene bubble" burst when the investment community became disenchanted with the deliverables of genomics, which were not quite as spectacular as promised. Now, a local researcher has predicted that the current hot topic of bioinformatics will not exist within the next ten years. Instead, its position will eventually be usurped by disciplines such as system biology and transcriptome research, which will be the focus for pharmaceutical research in the near future."
"System biology is an emergent field that aims at system-level understanding of biological systems. While system-level understanding has been a long-standing goal of biological sciences, it was only recently that system-level analysis, grounded on discoveries at molecular-level, could be made."
redux [06.24.03]
"The study of systems biology, the field of research that creates predictive models of complex biological processes, will lead to advances in pharmaceuticals and medical treatment, but also to advances in computer science, a leading systems biologist predicted Monday.
""I think biology is going to give fundamental new insights to IT," Hood said. "Really understanding the evolution of gene regulatory networks is going to provide completely new strategies for how one deals with this horrendous computational problem of taking big programs ... and restructuring them really efficiently so that you don't restructure them simply by adding more onto them.""

"One of the critical priorities now is to take all the components we can detect, and reconstruct the interaction networks inside cells that underlie biological processes. This type of reconstruction is very tricky: People call it 'integration of heterogeneous databases.' Collating these data files is like stacking playing cards -- each piece of data stands upon, and influences, the reliability of other pieces.
The next priority is then to generate computer models that can be used for simulations -- in silico biology. There are three categories of models we need to build: models for metabolism, DNA regulation, and cell signaling."

"Systems biology, a siren in a sea of dark prospects, has lured investors frustrated with low returns in biotechnology and anxious to set a new course of drug discovery. Institutions have also geared up training programs, but the excitement in the new field has failed to arrest downsizing in the biotech industry."
"Despite the interest of the pharmaceutical industry, prospective systems biologists should think carefully before investing in training in hopes of landing a job in the new field."

"To understand biology at the system level, we must examine the structure and dynamics of cellular and organismal function, rather than the characteristics of isolated parts of a cell or organism. Properties of systems, such as robustness, emerge as central issues, and understanding these properties may have an impact on the future of medicine. However, many breakthroughs in experimental devices, advanced software, and analytical methods are required before the achievements of systems biology can live up to their much-touted potential."

"Over the last few years, there's been an explosion of information in biology. The mapping of the human genome gave biologists unprecedented detail about some 30,000 to 40,000 genes. 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."

"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."

"Systems biology is a loosely defined term, but the main idea is that biology is an information science, with genes a sort of digital code. 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."

"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."

"Our Mission is to develop an integrated, easy-to-use environment, the workbench , which will enable biologists to create, manipulate, display and analyze biological models at molecular, cellular and multicellular levels. We are focusing on biochemical networks including mass action kinetics, metabolic pathways, stochastic simulation, gene expression and regulation."
"One of the key aspects of out project is to facilitate collaboration among existing developers and users of system biology software. We aim to do this by providing an open-source software infrastructure which will enable collaborators to freely use and share each other's computational resources."

"For most of us, formal biology education begins with complex systems--the traditional dissection of a frog in high school biology class is virtually a rite of passage in the U.S.
But the way many people learn about and invest in biotechnology is at the smallest end of the spectrum--the genome, now often described as the "periodic table" of biology. 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."

Scientists Abandon their Software
[requires 'free' registration]
"Vitacolonna isn't alone in abandoning a good project at the end of his postdoc term. It's a ritual of many a bioinformatician. If a person's postdoc project is wildly successful and published in multiple journals, he or she can continue overseeing the program in a junior professor job. If it's just ho-hum work, the creator will probably move on to more interesting projects on the next step up the career ladder.
In the field of bioinformatics, this process, which results in programs known as abandonware, has a debilitating impact."

NHGRI Releases RFAs for '$1,000 Genome'
"The National Human Genome Research Institute today released two RFAs aimed at reducing the costs of sequencing a single, full-length mammalian genome to $1,000 - down from current average costs of $10 to $50 million per genome - by the end of a 10-year time frame."
"The RFAs gave several potential applications of cost reduction efforts, including: expanding comparative genomic analysis across species, applying human genetic variation studies to individual health care, and analyzing microbial genomes for food and environment monitoring."

"Just before lunch today at the GSAC conference, Craig Venter stood before the crowd and announced a mouth-watering proposition: a $500,000 Genomic Technology Prize to be awarded by the J. Craig Venter Science Foundation to a person or organization that develops technology "to significantly advance" automated DNA sequencing toward making the $1,000 genome a reality.
"Look at [the number of] important medical, and environmental advances that would happen if we could sequence a genome in the same time as we are having this conversation," Venter told GenomeWeb News today after the session ended. "

"It's been three years since scientists completed a rough draft of the human genetic code, but nobody's rushing out yet for a personal DNA analysis. That's because the first draft took 12 years and cost billions of dollars.
Today, the cost has fallen, but only to around $50 million. The target price is orders of magnitude away: $1,000 for an individual's DNA sequence."

""We are proposing to give people their own sequence if they'll have it," says genomicist George Church of Harvard Medical School."
"Church and other experts think this is no longer a pipe dream. They believe that in less than a decade, people will be able to get their own genomes sequenced for about the price of a laptop or a flat-screen TV. When that happens, the thinking goes, a whole new industry of personal genomics will take off."

Scientists: The Latest Mac Converts
""For our [Mars] landing site work, we always get the highest-end desktop Mac we can find, so we just got one of the G5s with dual 2-GB processors and 8 GB of RAM," Matt Golombek, a planetary geologist at NASA's Jet Propulsion Laboratory, told the E-Commerce Times."
""If you pull up a shot of NASA after the [first] Mars landing and look at the desktops, you'll see a couple of PC laptops there, but you'll see more PowerBooks," Jon Rubinstein, senior vice president for hardware engineering at Apple, told the E-Commerce Times."

"Apple's focus on creating products that should be of use to the high-performance computing markets has spawned a new, little-known product combo - the Apple Workgroup Cluster for Bioinformatics.
This is a pre-configured bioinformatics cluster built around the new Xserve G5. The cluster includes between four and 16 servers, a rack to hold the them, cabling, and systems and application software. The bundled system includes The BioTeam's iNquiry software with 200 informatics applications including BLAST and HMMER. It costs from $27,999."
"To address raw HPC processing power needs, Apple introduced a new version of its Xserve rack-mounted server that includes the PowerPC G5 processor. The new Xserve G5 delivers more than 30 gigaFLOPS (30 billion floating point operations per second). This is about 60 percent more raw processing than the original Xserve, which used the PowerPC G4 processor."
"Apple has always been known for its easy-to-use products. So as the company moves into the enterprise HPC market, it is trying to retain the well-liked "ease-of-use" features in more-complex computing environments."

"Apple today previewed Xgrid, a computational clustering technology from Apple's Advanced Computation Group (ACG). Xgrid helps scientists and others working in compute intensive environments to fully utilize all IT resources, including desktops and servers, by creating a grid enabled "virtual" IT environment that takes advantage of unused computing capacity to run batch and workload processing."
""The Xgrid BLAST application enables bioinformatics researchers to perform distributed BLAST searches on a cluster running the Xgrid software," said Richard H. Scheller, Ph.D., senior vice president of Research, Genentech in the press release. "We tested Xgrid BLAST by querying DNA sequence files for matches against multi- gigabyte genomic databases on a cluster of four dual-processor Xserves.""

"Dr Elia Stupka (left), Bioinformatics Programme manager, Laboratory of Computational Biology said, "The Xserve is suitable to TTL because the operating system (OS) X Unix-based open source application can be ported and run easily. And integration with specific software tools is seamless.""
"In addition, he could use the same OS on his desktops, portable computers and network cluster. Stupka sought to tap on the unused computing power of all the devices in the cluster."
