I am very happy to announce that a first key work from the Folding@home project on Alzheimer's Disease (AD) was just published.
Simulating oligomerization at experimental concentrations and long timescales: A Markov state model approach, by Nicholas W. Kelley, V. Vishal, Grant A. Krafft, and Vijay S. Pande. J. Chem. Phys. 129, 214707 (2008); DOI:10.1063/1.3010881

Abeta misfolding and aggregation is believed to be the cause of Alzheimer's Disease. Simulations, like Folding@home, are a natural way to understand this process. However, there are several key challenges for simulating the key step -- oligomerization. This work represents a new way to simulate Abeta oligomerization, with a key advance of being able to simulate experimentally relevant timescales and concentrations, using a novel method. We use this new method and the power provided by Folding@home donors to simulate oligomerization in all-atom detail. This has lead to specific predictions about the process, which we are now testing experimentally.
In many ways, this paper is the "tip of the iceberg" for the Folding@home activities in AD, with a lot more interesting results to come, especially in terms of experimental tests of our predictions and interesting new possibilities for new drugs and AD therapeutics. So, while we're excited that this result is now past peer review, we're even more excited for what's coming down the pipeline, waiting peer review. We'll keep you posted as more results become public, hopefully with some even bigger announcements in 2009.
How does it work?: You download a safe, tested program (see link below) that is certified by Stanford University. It gets work from Stanford, runs calculations using your spare computer power, and sends the results back to the University.
Is it safe? Yes! Folding@Home rarely effects computer performance in any way and won't compromise your privacy in any way. It only uses the computing power you aren't using so it doesn't slow down other programs.
How do I get started folding for Team FreeRepublic?:
1.) Download the folding program from Stanford University's folding download page (Folding@home Client Download). Type in your desired user-name.
2.) Type in 36120 for the team number. THIS IS VERY IMPORTANT - if you get the number wrong, you won't be folding for team FreeRepublic!
3.) The third question asks, "Launch automatically at machine startup, installing this as a service?" - We recommend you answer YES. Otherwise you will have to manually start the program after every reboot.
How can my computer help? Even if they were given exclusive access to all of the world's supercomputers, Stanford still wouldn't have as much processing power as they get from the supercluster of people's desktop systems Folding@home relies on. Modern supercomputers are essentially a cluster of hundreds of processors linked by fast networking. But Stanford needed the power of hundreds of thousands of processors, not just hundreds.
There's no reason to not get involved! It's free, easy, and you can know you're helping every minute without lifting a finger.

Dr. Pande has published a new peer-reviewed article concerning the formation of certain peptides implicated in the development of Alzheimer's Disease.
While most of the article is lost to me in a fog from college biology past, it is great to see Folding complete a peer-reviewed article.
Net net - our work is making a difference with researchers across the world in finding a solid cure for Alzheimer’s Disease!

It's been a while since I've posted on this topic, so I thought it would be a good time to talk about the long term vision for FAH. In the first few years, we have done a lot to build up methodology (novel distributed computing algorithms, tests of methods), especially in the last years working to bring GPU’s, PS3’s, and tightly coupled SMP calculations to a distributed computing platform.
While all of this has been going on, there has been a lot of work which would have a direct impact to disease and human health, and donors should see more results (i.e. papers) coming out in this direction soon. In particular, results on Alzheimer's Disease, Huntington's Disease, and some other surprises in the works (sorry, some details are best left until peer review is done).
In terms of a long term vision for the FAH software, our short term goals is to shore up the SMP client. Just as there was a big improvement from the GPU1 -> GPU2 client, we have been working steadily on an SMP2 client — a version which is much easier to use, requires less donor effort, and scales much better. This really is a combination of a modified client and (especially) new cores. This effort has been going on for about a year and it's far enough along that I'm starting to talk about it publicly.
In the previous post, I also mentioned about some of our work behind the scenes in revamping the back end of FAH, i.e. a whole new set of server codes. We have code for the workserver and collection servers, but in time we expect the full back end to be cleanly rewritten from scratch.
Longer term, with a more solid GPU2 and SMP2 clients done, we can then move on to other areas. Our goal is to be bleeding edge in the nature of our science, but get back to the simplicity and stability found in the classic client. We still have a ways to go, but I am excited that projects that were started some time ago are now looking like they will see the light of day.

Active CPUS are defined as those which have returned WUs within 50 days. Active GPUs are defined as those which have returned WUs within 10 days (due to the shorter deadlines on GPU WUs). Active PS3's are defined as those which have returned WUs within 15 days. |

| *TFLOPS is the actual teraflops from the software cores, not the peak values from CPU/GPU/PS3 specs. Please see our main FAQ, PS3 FAQ, NVIDIA GPU FAQ, or ATI GPU FAQ for more details on specific platforms. |
Woo-hoo! I finally made it into the top 200 on our team!
I know, no big deal but I only have one computer folding.

fyi...
Egon (just) and Pseudocode (recently) broke a million!
