Vin Crosbie, on the challenges, financial and otherwise, that newspaper publishers are facing: "The real problem, Mr. Newspaperman, isn't that your content isn't online or isn't online with multimedia. It's your content. Specifically, it's what you report, which stories you publish, and how you publish them to people, who, by the way, have very different individual interests. The problem is the content you're giving them, stupid; not the platform its on."

There's a problem in the drug industry that people have recognized for some years, but we're not that much closer to dealing with it than we were then. We keep coming up with these technologies and techniques which seem as if they might be able to help us with some of our nastiest problems - I'm talking about genomics in all its guises, and metabolic profiling, and naturally the various high-throughput screening platforms, and others. But whether these are helping or not (and opinions sure do vary), one thing that they all have in common is that they generate enormous heaps of data.

Now that the Web labor market is saturated and Web design a static profession, it's not surprising that 'user experience' designers and researchers who've spent their careers online are looking for new worlds to conquer. Some are returning to the “old media” as directors and producers. More are now doing offline consulting (service experience design, social policy design, exhibition design, and so on) under the 'user experience' aegis. They argue that the lessons they've learned on the Web can be applied to phenomena in the physical and social worlds. But there are enormous differences...

Clay Shirky, in deconstructing Second Life hype: "Second Life is heading towards two million users. Except it isn’t, really... I suspect Second Life is largely a 'Try Me' virus, where reports of a strange and wonderful new thing draw the masses to log in and try it, but whose ability to retain anything but a fraction of those users is limited. The pattern of a Try Me virus is a rapid spread of first time users, most of whom drop out quickly, with most of the dropouts becoming immune to later use."

Over the last few years we've seen old barriers to creativity coming down, one after the other. New technologies and services makes it trivial to publish text, whether by blog or by print-on-demand. Digital photography has democratised a previously expensive hobby. And we're seeing the barriers to movie-making crumble, with affordable high-quality cameras and video hosting provided by YouTube or Google Video and their ilk... Music making has long been easy for anyone to engage in, but technology has made high-quality recording possible without specialised equipment, and the internet has revolutionised distribution, drastically disintermediating the music industry... What's left? Software maybe? Or maybe not."

Derek Lowe on the news that the Nobel Prize for medicine has gone to Craig Mello and Andrew Fire for their breakthrough work: "RNA interference is probably going to have a long climb before it starts curing many diseases, because many of those problems are even tougher than usual in its case. That doesn't take away from the discovery, though, any more than the complications of off-target effects take away from it when you talk about RNAi's research uses in cell culture. The fact that RNA interference is trickier than it first looked, in vivo or in vitro, is only to be expected. What breakthrough isn't?"

Andrew Phelps: "Recently my WoW guild has been having a bit of a debate on the merits of Player-vs.-Player (PvP) within Azeroth. My personal opinion on this is that PvP has its merits, and can be incredible fun, but the system within WoW is horridly, horribly broken. It takes into account the concept of the battle, but battle without consequence, without emotive context, and most importantly, without honor..."
From later in the piece: "When I talk about this with people (thus far anyway) I typically get one of two responses, either 'yeah, right on!' or 'hey, it’s war, and war isn’t honorable – grow the hell up'. There is a lot to be said for that argument – but the problem is that war in the real historical world has very different constraints that are utterly absent from fantasized worlds..."

Derek Lowe: "So, you're developing a drug candidate. You've settled on what looks like a good compound - it has the activity you want in your mouse model of the disease, it's not too hard to make, and it's not toxic. Everything looks fine. Except. . .one slight problem. Although the compound has good blood levels in the mouse and in the dog, in rats it's terrible. For some reason, it just doesn't get up there. Probably some foul metabolic pathway peculiar to rats (whose innards are adapted, after all, for dealing with every kind of garbage that comes along). So, is this a problem?.."

Bob Jacobson, on shopping at his local Albertsons supermarket where he had "one of the worst customer experiences" of his life: "Say what you will about the Safeway chain or the Birkenstock billionaires who charge through the roof for Whole Foods' organic fare, they know how to create shopping environments that create a more pleasurable experience, at its best (as at Whole Foods) quite enjoyable. Even the warehouses like Costco and its smaller counterpart, Smart & Final, do just fine: they have no pretentions, but neither do they dump virtual garbage on the consumer merely to create another trivial revenue stream, all for the sake of promotions in the marketing department..."

Corante Developments
Here you will find the latest news from Corante including updates on upcoming events, new initiatives, product and publication launches, and more.
It was with shock that I returned home from a night out last night to hear the news of Russell's passing. How terribly, terribly sad. Most of all for him, as he'd seemed buoyant, healthier, and content when I'd last seen him several months ago when he was in town - he was happy that work was busy and rewarding and was having fun with it but most of all was thrilled about how things were going with his girlfriend, Ellen.
I've known Russ for what seems like ages now (in a good way) though in fact it's only been about six or seven years since the early days of "commercial" blogging when he started working on various projects at and around Corante. He was a diligent, committed, and prolific journalist who had impressively and more ably than others been able to make the transition from the old-school way of doing things to the new. He had his quirks, as we all do, but I greatly valued that he was good-natured, collegial, reliable, quick to adopt, trustworthy, eager to learn, and earnest in his interest in helping others better understand what he wrote about.
He was also, it should be said, a kind and thoughtful soul and it was the rare conversation in which he didn't ask, with sincerity, about what he knew of my life, e.g. our new babe, and we didn't talk as seemingly old friends about our lives and respective paths. I can't say I knew him very well, of course, but in our half-dozen get-togethers over the years and dozens of conversations I got a good sense of the man: he cared about learning and sharing and his bearing was earnest and ego-less and we'll miss him for that and more.

We've been remiss in letting you know about two new independent blogs we've helped launch in the past month or so.
The first - the ConversationHub - is a companion blog to Supernova 2007, the latest edition of Kevin Werbach's excellent conference on all things connected. As the conference site says: "Supernova examines the effects of an increasingly connected world on business, life, and public policy. As disparate physical and social networks link with one another, a new societal network is rapidly evolving... The New Network is greater than the sum of its parts. It challenges us to re-create everything from the software and hardware we use...to the business models we employ...to the information and entertainment we encounter...to the ways we work and play."
Visit the ConversationHub and you'll find several dozen leading thinkers and doers, led by a few notable ringleaders, weighing in on the themes and trends of the day in technology and business. We encourage you to tune in - feel free to comment and even suggest topics and ideas for posts.
The second blog - Mobile Messaging 2.0 - convenes about a dozen top observers of the mobile messaging space for an intense discussion of the industry and where it's headed. Among its contributors are leading commentators, journalists and players in the field - tune in and you'll find them touching on topics such as mobile device design, messaging platforms, market pressures, user-generated content, interface design, and much, much more.
Also, if you visit the site, which is sponsored by Airwide Solutions, this week, you'll find live coverage and commentary from Global Messaging 2007, to which several of our contributors have traveled to hear about the latest developments from a broad spectrum of the industry's players and providers.
Be sure to catch the Office 2.0 Conference and hear from and engage with leading thinkers and doers in this exciting new market. Find out more here and be sure to use the code "GLDRK" for a special discount for Corante readers.

Deadly, Tiny, and Ready For Its Close-up, Mr. DeMille
Posted by Carl Zimmer
If you took a census of life on Earth, you'd probably find that the majority of life forms looked like this. It's a virus known as a bacteriophage, which lives exclusively in bacteria. There are about 10 million phages in every milliliter of coastal sea water. All told, scientists put the total number of bacteriophages at a million trillion trillion (10 to the 30th power). Bacteriophages not only make up the majority of life forms, but they are believed to have existed just about since life itself began. Since then, they have been evolving along with their hosts, and even making much of their hosts' evolution possible by shuttling genes from one host to another. Thanks in large part to bacteriophages, more and more bacteria are acquiring the genes they need to defeat antibiotics. Bacteriophages also kill off a huge portion of ocean bacteria that consume greenhouse gases. If you suddenly rid the world of all bacteriophages, the global climate would lurch out of whack.
It may seem strange that the world's most successful life form looks a bit like the ship-drilling robots that swarmed through The Matrix. But the fact is that the bacteriophage is nanotechnology of the most elegant, most deadly sort. To get a real appreciation of its mechanical cool, check out the movie from which this picture comes. (Big and small Quicktime.) The movie is based on the awesome work of Michael Rossmann of Purdue University and his colleagues. (Their most recent paper appears in the latest issue of Cell, along with even more cool movies.) Rossmann and company have teased apart pieces of a bacteriophage and have gotten a better understanding of how they work together. The phage extends six delicate legs in order to make contact with its host, E. coli.. Each leg docks on one of the bacteria's receptors, giving the phage the signal that it is time to inject its DNA. The legs bend so that its body pulls towards the bacterium. The pulling motion makes the base of the phage begin to spin like the barrel of a lock. A set of shorter legs, previously held flush against the base of the virus, unfold so that they can clamp onto the microbe's membrane. The phage's sheath, shown here in green, shrinks as its spiralling proteins slide over one another. A hidden tube emerges, which in turn pushes out a needle, which rams into the side of the bacterium. The needle injects molecules that can eat away at the tough inner wall of the microbe, and the tube then pushes all the way into the microbe's interior, where it unloads the virus's DNA.
It has taken a while, historically speaking, for scientists to come to appreciate just how sophisticated parasites such as bacteriophages can be, a subject I explored at length in my book Parasite Rex. The best human-designed nanotech pales in comparison to bacteriophages, a fact that hasn't been lost on scientists. Some have been using bacteriophages to build nanowires and other circuitry. Others see them as the best hope for gene therapy, if they can be engineered to infect humans rather than bacteria. In both cases, evolution must play a central role. By allowing the phages to mutate and then selecting the viruses that do the best job at whatever task the scientists choose, the scientists will be able to let evolution design nanotechnology for them. From the depths of deep time, one of the next great advances in technology may come. And perhaps some more work in Hollywood, I hope.
Bacteriophages are a truly incredible species of viral-like "organisms", but even more spectactular is their ability to be used for DNA delivery or transport of other nucleic acids as part of a treatment of attempt of gene therapy. Bravo for bringing them up and discussing their brillianc!

Not to mention their use as anti-microbial therapeutics, as was done almost 100 years ago by the Russians, was forgotten about or relegated to textbooks, and then rediscovered and repopularized by Fischetti and the group at Rockefeller (I think). I would pick the same nit as Seth over the term "life" or "organism", but I think is is arguably a matter of opinion.
Myself and one other member of Seyet LLC, Lee Gooding, created the 3D visualizations for Purdue University.
It was a great experience and I love working on scientifically accurate visualizations because of the advanced research and discoveries I have to learn about in the process.
I agree that these bacteriophages are quite amazing. When we first had a completed model of the bacteriophage built it was so incredible to see such a small biological structure that looks mechanical in nature. Also, that model was built directly from their research so it is highly accurate. It is not a representation. It still amazes me to look at that animation and know that I am seeing precisely how a virus can inject its DNA into e-coli.
The Structural Biology group at Purdue seems to be doing a lot of different work on DNA docking and delivery. It will be great to see what comes of the research over the years. Instead of taking pills filled with drugs maybe someday they will be filled with living organisms that can do a specific task inside our body such as dock to cancer cells.
If anyone has questions on the creation of the visualization feel free to ask.
Also, I have probably read many of Carl's articles without even knowing it since I am a big Popular Science and Discover fan. Look's like I will picking up a copy of his books as well.

Great article, only I disagree on one point though, sticking a needle into tisue and inject some chemical bond is not considered sophisticated when done by men, then why is it when a bacteriophage does a similar thing? (and probably infringes some hotheads patent in the process :-) )
It only shows that the process of doing such thing is a proven tactic in our evolution as we all share each others evolution to thrive ourselfs, oops sharing is forbidden nowadays, one wonders how patent laws will stop evolution in the end... lol... we just mutate lawyers into green goo... lol...
But on a serious note, nature works because of it's simplicity, don't let yourself fool by things that look complicated closeby, it's behaviour paterns are often simple and because of that they work.
A bacteriophage sticking a tube into tisue
to inject manipulating chemicals to reach it's goals is simple and expected behaviour.
I like your viewpoint, but I think it is a complex process and it is more advanced than a doctor and a needle.
This bacteriophage only sticks its needle into e-coli when its "legs" come across a specific receptor.
Imagine putting a ton of these little guys in your system and they can only attach to HIV and they carry something to kill it.
Also, for cancer treatment the toxic drug would only be able to go into the cancer cell and would not be able to invade healthy cells as well. Cancer patients would not have to live through the grueling side effects of chemotherapy.
Perhaps one day there will be a whole army of "helper" organisms in our bodies that act as a secondary immune system.
On a less serious note, you comments remind me of the movie Pi, where everything is simply and complexly mathematical and predictable.
Yeah, my experience with nature is that it _looks_ simple until you start peeling back the layers, because our brains are simple and so we assume other things must be simple. When a human being wants to inject something into something, we put a straight metal needle onto a glass tube with a plunger. When nature wants to do it, it builds an assembly of rotating proteins, a six-part docking assembly, creates solvents to eat through the walls... and when you look up even closer it's probably even more complicated, because this is the version that's been simplified for us to understand by a professional writer. Atoms are not billiard balls, our eyes don't just take a picture like cameras, and being able to describe something briefly doesn't make it simple.

It only shows that the process of doing such thing is a proven tactic in our evolution as we all share each others evolution to thrive ourselfs, oops sharing is forbidden nowadays, one wonders how patent laws will stop evolution in the end... lol... we just mutate lawyers into green goo... lol...
But on a serious note, nature works because of it's simplicity, don't let yourself fool by things that look complicated closeby, it's behaviour paterns are often simple and because of that they work.

to inject manipulating chemicals to reach it's goals is simple and expected behaviour.

I like your viewpoint, but I think it is a complex process and it is more advanced than a doctor and a needle.
This bacteriophage only sticks its needle into e-coli when its "legs" come across a specific receptor.
Imagine putting a ton of these little guys in your system and they can only attach to HIV and they carry something to kill it.
Also, for cancer treatment the toxic drug would only be able to go into the cancer cell and would not be able to invade healthy cells as well. Cancer patients would not have to live through the grueling side effects of chemotherapy.
Perhaps one day there will be a whole army of "helper" organisms in our bodies that act as a secondary immune system.
On a less serious note, you comments remind me of the movie Pi, where everything is simply and complexly mathematical and predictable.

Yeah, my experience with nature is that it _looks_ simple until you start peeling back the layers, because our brains are simple and so we assume other things must be simple. When a human being wants to inject something into something, we put a straight metal needle onto a glass tube with a plunger. When nature wants to do it, it builds an assembly of rotating proteins, a six-part docking assembly, creates solvents to eat through the walls... and when you look up even closer it's probably even more complicated, because this is the version that's been simplified for us to understand by a professional writer. Atoms are not billiard balls, our eyes don't just take a picture like cameras, and being able to describe something briefly doesn't make it simple.
