"Google’s IPO has also made big news this year as their current stock position places the net worth of the company at an amazing USD 130 billion. This brings them close to the giants of the industry IBM and is only trailed by biggest like Intel and Microsoft. However, the Google guys are not resting on their laurels, as they believe that there is much more to be done and achieved.

"Brin said in a statement: “It’s clear there’s a lot of room for improvement, there’s no inherent ceiling we’re hitting up on. Google has a large computational infrastructure – that could be very useful for microbiology or computational biology. I don’t think we particularly restrict ourselves or have a 20-year vision or anything like that. I don’t think we’re averse to doing something new.”"

"SERGEY BRIN and Larry Page have ambitious long-term plans for Google’s expansion into biology and genetics through the fusion of science, medicine and technology."

"Over dinner and plenty of wine in February, Brin discussed the prospects for genetics with Craig Venter, the maverick biologist who decoded the human genome.

Despite millions of dollars in funding and thousands of hours of computing time from America’s federal Department of Energy, Venter needed more help to unlock the molecular mysteries of life. It seemed to him that Google’s mathematicians, scientists, technologists, and computing power had the potential to vault his research forward. He pressed Brin hard to get Google involved."

"Not long after the dinner, Brin and Page teamed up with Venter."

"By the end of next year, Google intends to open an engineering center in the Valley that will employ 600. The company has said it wants to be in a place with a strong quality of life for its employees, with access to public transportation and amenities."

"Downtown Phoenix offers perfect geography, housing and the public transit amenities that Google wants, said John Chan, deputy director of the downtown development office."

"Downtown is the Valley’s financial center and it also has a growing cluster of biotechnology companies. That may interest Google, since the company is said to be intrigued by bioinformatics, the use of computers to characterize the molecular components of living things."

"Continuing yesterday's well executed web applications theme I've drafted a list of common sense "golden rules" for bioinformatics web application interfaces. After all, the underlying algorithm might be fantastic but if nobody can use it then you may as well have kept it to yourself.

When I say "golden rule", of course, I mean "generally, and in my opinion". If you've got more to add, or disagree with any of them, add a comment and I'll check it out."

"A Johns Hopkins researcher, with colleagues in Sweden and at the Fred Hutchinson Cancer Research Center, suggests that the traditional view of cancer as a group of diseases with markedly different biological properties arising from a series of alterations within a cell's nuclear DNA may have to give way to a more complicated view. In the January issue of Nature Reviews Genetics, available online Dec. 21, he and his colleagues suggest that cancers instead begin with "epigenetic" alterations to stem cells.

"We're not contradicting the view that genetic changes occur in the development of cancers, but there also are epigenetic changes and those come first," says lead author Andrew Feinberg, M.D., M.P.H., King Fahd Professor of Medicine and director of the Center for Epigenetics in Common Human Disease at Johns Hopkins."

"Although the human genome was sequenced more than five years ago, it can provide scientists with comparatively few clues to the origins and treatment of disease.

The bulk of that information lies buried in the "epigenome" -- from the Greek epi, meaning "in addition to." The epigenome consists of chemical "amendments" to strings of DNA that spell out the human genetic code.

Now, an international group of 40 leading cancer scientists are proposing a new effort -- the Human Epigenome Project -- to map these chemical modifications.

And it would appear some of these altered genes are passed on to future generations with a range of studies emerging to support the idea.

"In a written commentary, evolutionary biologist Massimo Pigliucci said that Ruden's experiment was "one of the most convincing pieces of evidence that epigenetic variation is far from being a curious nuisance to evolutionary biologists." Pigluicci doesn't go so far as to say that the heritable changes caused by Hsp90 alterations are Lamarckian, but Ruden does. "Epigenetics has always been Lamarckian. I really don't think there's any controversy," he says.

Not that Mendelian genetics is wrong; far from it. The increased understanding of epigenetic change and the recent evidence indicating its role in inheritance and development doesn't give epigenetics greater importance than DNA. Genetics and epigenetics go "hand in hand," says Ohlsson. In the case of disease, says Reik, "there are clearly genetic factors involved, but there are also other factors involved. My suspicion is that it will be a combination of genetic and epigenetic factors, as well as environmental factors, that determine all these diseases.""

"Genes are tricksters. They can be turned on or off -- and whether they're on or off decides whether the gene-owner will develop disease.

Gene researchers have embarked on a new field of research, called epigenomics, to determine whether genes are in the on or off position. This type of marker could prove an important diagnostic or therapeutic tool for all types of cancer.

"At Johns Hopkins, researchers are performing clinical trials on about 15 patients with leukemia and other cancers to find out if epigenomics might give pharmaceutical companies a lead for developing cancer drugs.

The research, like all epigenomics research, is studying a chemical found in everyone's DNA called cytosine. Cytosine is the only chemical of the four that make up human DNA (the others are adenine, thymine, and guanine) that is prone to a phenomenon called methylation. When cytosine is methylated, it tuns off its gene."

"And HapMap shows how differences between ethnic groups can be very subtle."

"But although the absolute differences between the various ethnic backgrounds are tiny, there are genetic trends that differ between ethnic groups. A given set of SNPs may be linked in one way in Asian populations for example, but in a different way in Europeans. Over the whole genome there are more differences between individuals than there are between ethnic groups, but such trends are still thought to be useful for targeting drugs.

Hudson stresses that not all people within an ethnic group share the same SNP pattern, so pharmaceutical companies should bear this in mind. "We would want to give a drug not based on the colour of someone's skin but based on the presence or absence of the genetic markers," he says."

What a difference five years can make. Today, we are witnessing a revolution in the understanding of health and disease, spurred on by the sequencing of the human genome and the subsequent creation of a map of human genetic variation. And, like most historic movements, this revolution has been given a name: personalized medicine."

"Will access to genomic technologies be equitable? Will knowledge of human genetic variation reduce prejudice or increase it? What boundaries will need to be placed on this technology, particularly when applied to enhancement of traits rather than prevention or treatment of disease? Will we succumb to genetic determinism, neglecting the role of the environment and undervaluing the power of the human spirit?"

I hope that by 2010, we emerge as a significant contributor to the global bioinformatics sector. The basic infrastructure — high performance computing machines — has just arrived in the country at IISc, IITs, TIFR and CSIR laboratories. "

"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."

As an academic branch of learning, bioinformatics remains mostly what it always was -- a cross-disciplinary endeavor between computer science and molecular biology. But bioinformatics as a money-making proposition has different criteria for success, and it has received a lot of bad press lately, some of it deserved."

"During this golden age, bioinformaticists developed software that computational biologists could use to make biological discoveries based on genomic data. But the industry swerved off course by selling expensive systems that focused on the individual pieces of a solution, without heeding downstream processes that were the actual bread-and-butter of our customers.
