Biodesic has assembled several alpha test units of the next LavaAmp hardware revision.  We've replaced the original thin film heaters (which I screen printed by hand -- not fun solvents) with a new design.  Here is a photo, with my battered iPhone for scale.  Next up is switching from the aluminum case to something injection molded, and sorting out the sample loop design and manufacturing.

I recently had cause to re-read the National Strategy for Counter Biological Threats (Full PDF), released last fall by the National Security Council and signed by the President.  I think there is a lot to like, and it demonstrates a welcome change in the mindset I encounter in Washington DC. (Update: Fixed the broken link to the PDF.  Sorry about that.)

When the document came out, there was just a little bit of coverage in the press.  Notably, Wired's Threat Level, which usually does a commendable job on security issues, gave the document a haphazard swipe, asserting that "Obama's Biodefense Strategy is a Lot Like Bush's".  As described in that post, various commentators were unhappy with the language that Under Secretary of State Ellen Tauscher used when announcing the Strategy at a BWC meeting in Geneva.  According to Threat Level, "Sources tell this reporter that the National Security Council had some Bush administration holdovers in charge of editing the National Strategy and preparing Ms. Tauscher's script, and these individuals basically bulldozed the final draft through Defense and State officials with very little interagency input and with a very short suspense."  Threat Level also asserts that "Most are disappointed in the language, which doesn't appear to be significantly different than the previous administration."  It is unclear who "Most" are.

In contrast to all of this, in my view the Strategy is a clear departure from the muddled thinking that dominated earlier discussions.  By muddled, I mean security discussions and policy that, paraphrasing just a little, went like this: "Biology Bad!  Hacking Bad!  Must Contain!" 

The new National Strategy document, however takes a very different line.  Sources tell this reporter, if you will, that the document resulted from a careful review that involved multiple agencies, over many months, with an aim to develop the future biosecurity strategy of the United States in a realistic context of rapidly spreading infectious diseases and international technological proliferation driven by economic and technical needs.  To wit, here are the first two paragraphs from the first page (emphasis added, of course):

We are experiencing an unparalleled period of advancement and innovation in the life sciences globally that continues to transform our way of life. Whether augmenting our ability to provide health care and protect the environment, or expanding our capacity for energy and agricultural production towards global sustainability, continued research and development in the life sciences is essential to a brighter future for all people.

The beneficial nature of life science research is reflected in the widespread manner in which it occurs. From cutting-edge academic institutes, to industrial research centers,
to private laboratories in baseĀ­ments and garages, progress is increasingly driven by innovation and open access to the insights and materials needed to advance individual initiatives.
Recall that this document carries the signature of the President of the United States.  I'll pause to let that sink in for a moment.

And now to drive home the point: the new Strategy for Countering Biological Threats explicitly points to garage biotech innovation and open access as crucial components of our physical and economic security.  I will note that this is a definite change in perspective, and one that has not fully permeated all levels of the Federal bureaucracy and contractor-aucracy.  Recently, during a conversation about locked doors, buddy systems, security cameras, and armed guards, I found myself reminding a room full of biosecurity professionals of the phrase emphasized above.  I also found myself reminding them -- with sincere apologies to all who might take offense -- that not all the brains, not all the money, and not all the ideas in the United States are found within Beltway.  Fortunately, the assembled great minds took this as intended and some laughter ensued, because they realized this was the point of including garage labs in the National Strategy, even if not everyone is comfortable with it.  And there are definitely very influential people who are not comfortable with it.  But, hey, the President signed it (forgive me, did I mention that part already?), so everyone is on board, right?

Anyway, I think the new National Strategy is a big step forward in that it also acknowledges that improving public health infrastructure and countering infectious diseases are explicitly part of countering artificial threats.  Additionally, the Strategy is clear on the need to establish networks that both promulgate behavioral norms and that help disseminate information.  And the new document clearly recognizes that these are international challenges (p.3):

Our Strategy is targeted to reduce biological threats by: (1) improving global access to the life sciences to combat infectious disease regardless of its cause; (2) establishing and reinforcing norms against the misuse of the life sciences; and (3) instituting a suite of coordinated activities that collectively will help influence, identify, inhibit, and/or interdict those who seek to misuse the life sciences.

...This Strategy reflects the fact that the challenges presented by biological threats cannot be addressed by the Federal Government alone, and that planning and participation must include the full range of domestic and international partners.
Norms, open biology, better technology, better public health infrastructure, and better intelligence: all are themes I have been pushing for a decade now.  So, 'nuff said on those points, I suppose.

Implementation is, of course, another matter entirely.  The Strategy leaves much up to federal, state, and local agencies, not all of whom have the funding, expertise, or inclination to follow along.  I don't have much to say about that part of the Strategy, for now.  But I am definitely not disappointed with the rest of it.  It is, you might say, the least bad thing I have read out of DC in a long time.

Big Gene Patent (Busting) News???

| 2 Comments | No TrackBacks
Well now, isn't this an interesting development.  As covered by many news outlets (NYT, Wired, Genomeweb), US District Court Judge Robert Sweet has invalidated several US patents, sometimes referred to as the "BRCA1/2 patents", held by the University of Utah and Myriad Genetics.  From Judge Sweet's decision: "Products of nature do not constitute patentable subject matter absent a change that results in the creation of a fundamentally new product."  Judge Sweet's decision is here (PDF) via Genomics Law Report.  Here is the ACLU's take.

Here is a brief summary of what follows: The ruling is remarkable.  Various commentators and reporters remark upon it.  They get confused.  I try to clarify.  Then we get to a truly revolutionary part of the decision: it's about science!  And a little bit about law.  Finally: so what if a few patents are invalidated?
 

Didn't See That Coming.  But I Can't Complain.

Last month, I noted that I was skeptical that the ACLU and other plaintiffs would be so successful in one go.  So I am surprised, but I am certainly not disappointed.  But I am not surprised, while being somewhat disappointed, that the coverage of the decision is so confused and confusing.  This confusion arises, I suspect, because the wording of Judge Sweet's decision is not entirely straightforward in places, and this has led to analyses that are insufficiently careful.  More on these points below.

DISCLAIMER: Please recall in what follows that I am but a humble physicist by training (oh yes, yes, we're all very humble), not a lawyer.  But I have written some stuff about patents on genes, and at least a few people (some of whom are IP law lawyers) think my analysis doesn't suck a lot.

First, over at Genomics Law Report (GLR), John Conley and Dan Vorhaus have a great analysis with a nice title: "Pigs Fly: Federal Court Invalidates Myriad's Patent Claims".  I won't bother to repeat their discussion.  If you are interested in this issue, please read that post as well as Dan Vorhaus' initial post analyzing the decision.  In particular, the reader might want to attend closely Vorhaus and Conley's observations about the potential for appeals, the likelihood of success in that endeavor, and the applicability of the ruling in other jurisdictions.

The short summary of what's transpired so far in the case is that Judge Sweet has invalidated a small number of claims, in a summary judgement ruling that so far applies only in the Southern District of New York.  Assertions that this is the end of the world for companies that hold gene patents are rather overblown.

There's Too Much Confusion, But Here is Some Relief

But now onto some of the confusing bits alluded to above.  The confusion starts, surprisingly, at GLR.  Here are Conely and Vorhaus:  "In the broader policy debate surrounding gene and biotechnology patents, however, this decision is the latest, unmistakable shot across the bow of gene patent holders, particularly those such as Myriad Genetics that have developed businesses around patent-protected genetic tests supported by exclusive rights in underlying gene patents."  Hummm...  Maybe not so much, actually.  Let me get straight to the point: there is a rather substantial difference between a "gene patent" that claims naturally occurring sequences and one that claims sequences that are not natural. 

Here is one way to think about the issues under discussion: in my one hand, I have a piece of isolated DNA that is identical in sequence to one in your body.  It is the same genetic sequence, so it carries the same information.  Indeed, for it to be useful in a test tube for the purposes of diagnosis, it must have both the same information content and the same function as the sequence in your body.  In fact, it only works as a diagnostic tool because it is the same as what is in your body.  As I noted in my earlier post, this is sort of the opposite of invention, and I have never understood why natural genes can be patented.  (Note: Judge Sweet hits this point quite squarely, but not until p.124 of his ruling.)  In my other hand, I have a piece of isolated DNA that is solely the result of human manipulation -- "human ingenuity" -- consisting of a sequence that does not exist in nature.  Both pieces of DNA are isolated, but they derive from very different sources, and are derived by very different means. Unfortunately, everybody discussing the present decision, including Judge Sweet in the early pages of his decision, seems to be a tad careless about the distinction, which leads many people down a rabbit hole.  (There is an extended discussion of the definition of "isolated DNA" and of the BRCA1/2 genes on p.90-92.)

Here is where it starts: Judge Sweet sets up his decision in the first couple of pages focusing specifically on the BRCA1/2 genes, and slightly more generally on isolated human genes: "Are isolated human genes and the comparison of their sequences patentable?" (p.2)  He continues: "Two complicated areas of science and law are involved: molecular biology and patent law.  The task is to seek the governing principles in each and to determine the essential elements of the claimed biological compositions and processes and their relationships to the laws of nature."

This sounds great.  Judge Sweet is clearly referring specifically to certain human gene sequences named in the patents in question.  Alas, on the next page he switches his language to address the specific assertions of the plaintiffs that ""isolated DNA" containing human BRCA1/2 sequences" are not patentable.  The basic contention here is that because the isolated DNA as described in the patents does the same thing inside the body as outside the body -- it is an information storage medium -- there is no difference between the two forms of DNA and therefore the isolated DNA in question cannot be patented.  Judge Sweet concludes (p.4):

DNA represents the physical embodiment of biological information, distinct in its essential characteristics from any other chemical found in nature. It is concluded that DNA's existence in an 'isolated' form alters neither this fundamental quality as it exists in the body not the information it encodes.  Therefore, the patents at issue directed to "isolated DNA" containing sequences found in nature are unsustainable as a matter of law and are deemed unpatentable subject matter.
The judge thereby switches within a couple of paragraphs very seamlessly from language referring only to human genes to language referring seemingly to all "isolated DNA".  It takes another 100 pages to get to a true clarification, and I'll bet very few people have read that far, or followed all the byways and cross-references (p.100): "...The issue presented by the instant motions with respect to the composition claims is whether or not claims directed to isolated DNA containing naturally-occurring human sequences [emph added] fall within the products nature exception.  ...It is concluded that the composition claims-in-suit are excepted."

In other words, Judge Sweet very specifically ruled that the claims on isolated DNA containing naturally occurring sequences are not valid.  Even more specifically, the ruling only applies to the motion in question by the plaintiffs, namely to invalidate the patents on BRCA1/2 held by Myriad et al.  Judge Sweet pointedly cites Diamond vs. Chakrabarty (p.109) -- a case that affirmed the patentability of "genetically engineered" organisms -- in limiting his ruling to the patentability of naturally occurring genes.  The ruling has no applicability outside that subject matter, and therefore has little applicability to, for example, much of anything that might come out of synthetic biology (unless you are talking about a synthetic DNA version of a naturally occurring gene).  Nor, for that matter, does the ruling have any say about any bit of DNA altered to be different from a natural sequence.  Which means that the ruling has very little to do with most patents on DNA, and therefore has very little to do with most of the industry surrounding those patents -- more on this below.

(Side note, as I read through the decision: Myriad's lawyers didn't do themselves any favors by making generally unpersuasive assertions aimed as broadside attacks against the plaintiffs' arguments.  As noted in my previous post on this case "Whither Genome Patents?", the defendants' assertions that patents serve as necessary incentives for scientific research are complete bunk.  Defense attorney Brian Poissant previously argued that "women would not even know they had BRCA gene if it weren't discovered" under a system that incentivizes patents.  I say again, as calmly as I can, bull pucky.  For example, see the publicly funded Human Genome Project.  See also the fact that BRCA2 was sequenced first in academic labs rather than by Myriad, who somehow managed to patent it anyway.  See also the many  BRCA1/2 assays independently developed in academia, the use of which Myriad repeatedly quashed through cease-and-desist letters, as recounted in detail in the decision.  But here is Judge Sweet himself (p.76): "According to Myriad, its policy and practice has been and still is to allow scientists to conduct research studies on BRCA 1 and BRCA 2 freely, the result of which has been the publication of [over 8600 papers] representing the work of over 18,000 scientists."  (It wasn't clear to me whether Myriad's legal team itself provided these numbers -- but if they did: bad legal tactics, fellas.)  In other words, 18,000 scientists have managed to produce a substantial body of work without any promise whatsoever of remuneration based on a patent for BRCA1/2.  Unless, of course, you count keeping your job through the promise of not being sued by Myriad.)  

It's Science!  And Science Always Wins -- Eventually, But May be Delayed By Appeals.

There is another very interesting angle to Judge Sweet's decision.  Andrew Pollack, writing in the New York Times, suggests that the most revolutionary part of the decision is where Judge Sweet recognizes that DNA carries information.  Pollack quotes Rebecca Eisenberg, a law professor at the University of Michigan: "There isn't a whole lot of doctrinal support" for considering DNA as information rather than as a chemical.  That, for me, is a truly eye opening perspective.  Not because I didn't know about it before -- unfortunately, that view is all too prevalent among IP lawyers -- but rather because it is being defended and suggested as a possible grounds for appeal.  True, it may be precedent, but that does not mean it is good precedent.

Here's the thing: There may not be much "doctrinal support" for considering DNA as information, but there is a rather overwhelming amount of scientific and technical support for considering DNA as information rather than as a chemical, say starting with the vast majority of molecular biology and biochemistry papers published in Science, Nature, Cell, PNAS, and any other relevant journal you can think of.  For all of the last six decades, no less.  Oh, and then all those silly textbooks.  The genetics and molecular biology ones, obviously; not the law textbooks.

Judge Sweet, in my humble opinion, already smacked this one out of the park on p.4: "The facts relating to molecular biology are fundamental to the patents at issue and to the conclusions reached.  Consequently, in the findings which follow, the discussion of molecular biology precedes the facts concerning the development, application, and description of the patents."  (Whoa there!  Science and reason trump the law of man!  Or science and reason trump the law of lawyers?  Damn, now that is a novel legal theory.  And a welcome one.  Don't tell Sen. James Inhofe.) 

Unfortunately, Pollack misses this angle, and promulgates further the confusion that Judge Sweet's ruling spells doom for the biotech industry: "Some biotechnology investors and executives say that lack of patent protection for DNA could diminish investment in the field and remove incentives for companies to develop tests."  Never mind that, as described above, Judge Sweet's ruling applies only to patents on naturally occurring genes, which should ameliorate the concerns of most of the "some biotechnology investors and executives".  It is nonetheless true that diagnostics companies that rely on patents claiming naturally occurring sequences may have to reevaluate their business plans.  (For instance, they may want to be especially careful in issuing cease-and-desist letters, lest the ACLU and company get busy again.)  And it may be true that this small fraction of biotech businesses may have difficulty raising capital -- but time will tell.  If it turns out that development of new diagnostic assays lags as a result of more patents on human genes being invalidated, then we will have something real to talk about.  We might consider developing public policy around alternate incentives.  Until there is a demonstrated concern, however, it isn't clear to me that we should be so concerned about the fate of private investors who gambled on patents whose validity has long been questioned.

What Is The Real Impact Going To Be? 

To reiterate the numbers from my earlier post: of the roughtly 2% of US GDP that is derived from biotech, at a rough guess I would put only 1% of the total (so .01% of US GDP) in the molecular diagnostics category that depends explicitly on excluding other uses of patented human genes.  A few billion dollars a year, in other words, might be at risk.  But somebody is going to do the tests, and Judge Sweet's decision lists a variety of tests that cost about 1/3 of Myriad's; that is, before Myriad shut them down with cease-and-desist letters.  If you eliminate those patents, we might have to come up with some other way to incentivize the development and testing of assays.  Prizes come to mind as a fine thing to try.  They work.  Academics and garagistas will be happy to compete for those prizes, I am sure.

But the rest of the biotech industry shouldn't be concerned about this ruling, frankly.  They might even celebrate the fact that they now have access, potentially, to a whole bunch more genes that are naturally occurring.  Not just in humans, mind you, but any organism.  This opens up a rather substantial toolbox for anybody interested in using biological technologies derived from viruses, bacteria, plants, etc.  If it holds up over the long run, Judge Sweet's decision should accelerate innovation.  That is definitely a good thing.

DIY Cleanroom

Gizmodo and Make are both pointing to Bill Morris's DIY Cleanroom.  Compare it to the hoods shown in my post on Garage Biology in Silicon Valley a couple of days ago.

Morris reports that his goal is a Class 10,000 hood, a specification that is slightly more involved than I had remembered.

In any event, Morris' hood would be of great use to those doing cell culture at home.  I suspect you are going to want a better filter, for nabbing smaller contaminants, maybe higher airflow, and perhaps some way to hack up a laminar-flow set-up.

Cool.

Whither Gene Patents?

| No Comments | No TrackBacks
Wired and GenomeWeb (subscription only) have a bit of reporting on arguments in a case that will probably substantially affect patents on genes.  The case is Association of Molecular Pathology , et al. v. US Patent and Trademark Office, otherwise known as "the BRCA1 case", which seeks to overturn a patent held by Myriad Genetics on a genetic sequence correlated with breast cancer.

Here is a brief summary of what follows: I have never understood how naturally occurring genes can be patentable, but at present patents are the only way to stake out a property right on genes that are hacked or, dare I say it, "engineered".  So until IP law is changed to allow some other form of protection on genes, patents are it.

The ACLU is requesting a summary judgment that the patent in question be overturned without a trial.  Success in that endeavor would have immediate and enormous effect on the biotech industry as a whole, and I doubt the ACLU is going to get that in one go.  (Here is the relevant recent ACLU press release.)

However, the lawsuit explicitly addresses the broader question of whether any patents should have been granted in the first place on human genes.  This gets at the important question of whether isolating and purifying a bit of natural DNA counts as an invention.  Myriad is arguing that moving DNA out of the human genome and into a plasmid vector counts as sufficient innovation.  This has been at the core of arguments supporting patents on naturally occurring genes for decades, and it has never made sense to me for several reasons.  First, changing the context of a naturally occurring substance does not constitute an invention -- purifying oxygen and putting it in a bottle would never be patentable.  US case law is very clear on this matter.  Second, moving the gene to a new context in a plasmid or putting into a cell line for expression and culturing doesn't change its function.  In fact, the whole point of the exercise would be to maintain the function of the gene for study, which is sort of the opposite of invention.  Nonetheless, Myriad wants to maintain its monopoly.  But their arguments just aren't that strong.

GenomeWeb reports that defense attorney Brian Poissant, argued that "'women would not even know they had BRCA gene if it weren't discovered' under a system that incentivizes patents."  This is, frankly, and with all due respect, a manifestly stupid argument.  Mr. Poissant is suggesting that all of science and technology would stop without the incentive of patents.  Given that most research doesn't result in a patent, and given that most patent application are rejected, Mr. Poissant's argument is on its face inconsistent with reality.  He might have tried to argue more narrowly that developing a working diagnostic assays requires a guarantee on investment through the possession of the monopoly granted by a patent.  But he didn't do that.  To be sure, the assertion that the particular gene under debate in this case would have gone undiscovered without patents is an untestable hypothesis.  But does Mr. Poissant really want the judge to believe that scientists around the world would have let investigation into that gene and disease lie fallow without the possibility of a patent?  As I suggested above, it just isn't a strong argument.  But we can grind it further into the dust.

Mr. Poissant also argued "that if a ruling were as broadly applied here as the ACLU would like then it could 'undermine the entire biotechnology sector.'"  This is, at best, an aggressive over generalization.  As I have described several times over the past couple of years (here and here, for starters), even drugs are only a small part of the revenues from genetically modified systems.  Without digging into the undoubtedly messy details, a quick troll of Google suggests that molecular diagnostics as a whole generate only $3-4 billion a year, and at a guess DNA tests are probably a good deal less than half of this.  But more importantly, of the nearly ~2% of US GDP (~$220-250 billion) presently derived from biological technologies, the vast majority are from drugs, plants, or bacteria that have been hacked with genes that themselves are hacked.  That is, both the genes and the host organisms have been altered in a way that is demonstrably dependent on human ingenuity.  What all this means is that only a relatively small fraction of "the entire biotechnology sector" is related to naturally occurring genes in the first place.   

I perused some of the court filings (via the Wired article), and the defense needs to up its game.  Perhaps they think the weight of precedent is on their side.  I would not be as confident as they are. 

But neither is the plaintiff putting its best foot forward.  Even though I like the analysis made comparing DNA patents to attempts to patent fresh fruit, it is unclear to me that the ACLU is being sufficiently careful with both its logic and its verbiage.  In the press release, ACLU attorey Chris Hansen is quoted as saying "Allowing patents on genetic material imposes real and severe limits on scientific research, learning and the free flow of information."  GenomeWeb further quotes the ACLU's Hansen as saying "Patenting human genes is like patenting e=mc2, blood, or air."

As described above, I agree that patenting naturally occurring genes doesn't make a lot of sense.  But we need some sort of property right as an incentive for innovators.  Why should I invest in developing a new biological technology, relying on DNA sequences that have never occurred in nature, if anybody can make off with the sequence (and revenues)?  As it happens, I am not a big fan of patents -- they cost too damn much.  At present, the patent we are pursuing at Biodesic is costing about ten times as much as the capital cost of developing the actual product.  Fees paid to lawyers account for 90% of that.  If it were realistically possible to engage the patent office without a lawyer, then the filing fees would be about the same as the capital cost of development, which seems much more reasonable to me.

I go into these issues at length in the book.  Unfortunately, without Congressional action, there doesn't seem to be much hope for improvement.  And, of course, the direction of any Congressional action will be dominated by large corporations and lawyers.  So much for the little guy.

Video from The Economist's World in 2010 Festival

| No Comments | No TrackBacks
The Economist has posted video from the World in 2010 Festival, held in Washington DC in early December.  The Innovation panel is below, with me (Biodesic), Dean Kamen (DEKA Research), Dwayne Spradlin (Innocentive), and Kai Huang (Guitar Hero), moderated by Mathew Bishop (The Economist).  (Here is a link to video selections from the rest of the event.)  I was chatting with a reporter a few days ago who observed that everyone else on the panel is quite wealthy -- hopefully that bodes well for me in 2010.  But maybe I am destined always to be the odd man out.  C-Span is re-running the video periodically on cable if you want to watch it on a bigger screen, but I can't seem to find an actual schedule.  (Here is their web version: Innovation in 2010.)


I have a couple of general thoughts about the event, colored by another meeting full of economists, bankers, and traders that I attended in the last week of December.  I met a number of fantastically accomplished and interesting people in just a few hours, many of whom I hope will remain lifelong friends. 

First, I have to extend my thanks to The Economist -- they have been very good to me over the last 10 years, beginning in 2000 by co-sponsoring (with Shell) the inaugural World in 2050 writing competition.  (Here is my essay from the competition (PDF).  It seems to be holding up pretty well, these 10 years later, save the part about building a heart.  But at least I wasn't the only one who got that wrong.)

Here is a paraphrased conversation over drinks between myself and Daniel Franklin, the Executive Editor of the newspaper.

Me:  I wanted to thank you for including me.  The Economist has been very kind to me over the past decade.
Franklin: Well, keep doing interesting things.
Me:  Umm, right.  (And then to myself: Shit, I have a lot of work to do.)

On to the World in 2010 Festival.  The professional economists and journalists present all seem to agree that we have seen the worst of the downturn, that the stimulus package clipped the bottom off of whatever we were falling into, and that employment gains going forward could be a long time in coming.  Unsurprisingly, the Democratic politicians and operatives who turned up crowed about the effects of the stimulus, while the Republicans who spoke poo-pooed any potential bright spots in, well, just about everything.

At the other meeting I attended, last week in Charleston, SC, one panel of 10 people, composed Federal reserve and private bankers, traders, and journalists couldn't agree on anything.  The recovery would be V shaped.  No, no, W shaped.  No, no, no, reverse square root shaped (which was the consensus at The World in 2010 Festival).  No, no, no, no, L shaped.  But even those who agreed on the shape did not agree on anything else, such as the availability of credit, employment, etc.

Basically, as far as I can tell, nobody has the slightest idea what the future of the US economy looks like.  And I certainly don't have anything to add to that.  Except, of course, that the future is biology.

Here is John Oliver's opening monologue from the Festival.  He was absolutely hilarious.  Unfortunately you can't hear the audience cracking up continuously.  I nearly pissed myself.  Several times.  (Maybe the cocktails earlier in the evening contributed to both reactions.)



Back to Innovation in 2010.  Dean Kamen had this nice bit in response to a question about whether the imperative to invent and innovate has increased in recent years (see 36:20 in the C-Span video): "7 billion people can't be recipients, they have to be part of the solution.  And that is going to require advanced technologies to be properly developed and properly deployed more rapidly than ever before."

To this I can only add that we are now seeing more power to innovate put into the hands of individuals than has ever occurred in the history of humanity.  Let's hope we don't screw up.

Can't believe it's finally here.

A Spot of Tea at The Economist

| No Comments | No TrackBacks
While in London last month I sat down for tea and an interview with Geoff Carr at The Economist (permalink).  We covered a lot of ground, though as befitting a brief chat over tea we didn't get too deep in to the weeds.  Alas, they cut out the bit where the good Dr. Carr tried to put milk in my peppermint tea.  A topic for discussion in itself.



The Times is running a nice profile piece on Eric Schadt and his work at Rosetta and now Sage Bionetworks.

Biodesic evaluated systems biology investments for a large organization about 18 months ago, and Schadt's approach makes more sense to me -- by far -- than anything else we looked at.  I sat in on the pitch that Schadt and Stephen Friend made to that same organization, and it was crystal clear to me that Sage -- now residing at the Hutch here in Seattle -- should be on the receiving end of piles of money.  The stacks of Nature Group publications Schadt is accumulating suggest he is on to something, and it appears that his methods can be used to make predictions about the behaviors of complex networks.  Time and experimentation will tell, of course.  The open source aspect is a huge bonus.

Schadt's move to Pacific Biosciences is interesting because during his talk he suggested that genome sequencing provides enough information about variation to fuel his statistical methods for predicting interactions not just between genes but between tissues -- he is working at the level of describing the behavior of networks of networks.  It seems he will now have access to plenty of data.
