The Mentor Page: (Want to mentor OLPC/XO code creation) >From slashdot.org: "Just wanted to drop a line reminding open source projects that they only have until March 12th (Pacific time) to apply for Google's Summer of Code. We are accepting more organizations this year than last because we want to add a couple hundred more students to the program. If you are part of a great project or know someone who is, we'd love to see an application. Please note that this is for organizations and not for prospective students, that's not for a few more weeks (see the program timeline)!" http://code.google.com/soc/2008 http://code.google.com/soc/2008/org_signup.html The student page: http://groups.google.com/group/google-summer-of-code-announce/web/guide-to-the-gsoc-web-app-for-student-applicants Henry Brown [EMAIL PROTECTED] cell 795-3680 office 505 827-2509

Schwartz Cc: [email protected]; [EMAIL PROTECTED] Subject: OLPC Tricoder for field doctors >From Ben Schwartz: "reading a microarray typically requires a high-resolution digital fluorescence microscope, which is very expensive" OLPC could be connected to USB chip for fast/cheap diagnostics. http://www.ece.ualberta.ca/~chrisb/research/lifesciencemain.htm January 29, 2008 Genetic testing Lab on a chip for less than $100 Canadian <http://nextbigfuture.com/2008/01/genetic-testing-lab-on-chip-for-100.html> Since a journal article was submitted to the Royal Society of Chemistry, the U of Alberta researchers have already made the processor and unit smaller and have brought the cost of building a portable unit for genetic testing down to about $100 Cdn. <http://www.eurekalert.org/pub_releases/2008-01/uoa-loa012808.php> In addition, these systems are also portable and even faster (they take only minutes). Backhouse, Elliott and McMullin are now demonstrating prototypes of a USB key-like system that may ultimately be as inexpensive as standard USB memory keys that are in common use - only tens of dollars. It could help with Pandemic disease control and detecting and controlling tainted water supplies. This development fits in with my belief that there should be widespread inexpensive blood, biomarker and genetic tests <http://nextbigfuture.com/2007/11/proposal-for-widespread-monitoring-and_09.html> to help catch disease early and to develop an understanding of biomarker changes to track disease and aging development. We can also create adaptive clinical trials to shorten the development and approval process for new medical procedures <http://nextbigfuture.com/2007/12/biomarkers-and-adaptive-clinical-trials.html> The device is now much smaller than size of a shoe-box (USB stick size) with the optics and supporting electronics filling the space around the microchip Canadian scientists have succeeded in building the least expensive portable device for rapid genetic testing ever made <http://www.rsc.org/Publishing/ChemScience/Volume/2008/02/Genetic_testing_shoe-box.asp> . The cost of carrying out a single genetic test currently varies from hundreds to thousands of pounds, and the wait for results can take weeks. Now a group led by Christopher Backhouse <http://www.ece.ualberta.ca/~chrisb/> , University of Alberta, Edmonton, have developed a reusable microchip-based system that costs just 500 (pounds) to build, is small enough to be portable, and can be used for point-of-care medical testing. To keep costs down, 'instead of using the very expensive confocal optics systems currently used in these types of devices we used a consumer-grade digital camera', Backhouse explained. The device can be adapted for used in many different genetic tests. 'By making small changes to the system you could test for a person's predisposition to cancer, carry out pharmacogenetic tests for adverse drug reactions or even test for pathogens in a water supply,' said Backhouse. The heart of the unit, the 'chip,' looks like a standard microscope slide etched with fine silver and gold lines. That microfabricated chip applies nano-biotechnologies within tiny volumes, sometimes working with only a few molecules of sample. Because of this highly integrated chip (containing microfluidics and microscale devices), the remainder of the system is inexpensive ($1,000) and fast. There are many possible uses for such a portable genetic testing unit: Backhouse notes that adverse drug reactions are a major problem in health care. By running a quick genetic test on a cancer patient, for example, doctors might pinpoint the type of cancer and determine the best drug and correct dosage for the individual. Or health-care professionals can easily look for the genetic signature for a virus or E. coli - also making it useful for testing water quality. "From a public health point of view, it would be wonderful during an epidemic to be able to do a quick test on a patient when they walk into an emergency room and be able to say, 'you have SARS, you need to go into that (isolation) room immediately.' " A family doctor might determine a person's genetic predisposition to an illness during an office visit and advise the patient on preventative lifestyle changes.

MATLAB is not required. If you can make the case for microarray analysis, appropriate software can be created easily enough. reading a microarray typically requires a high-resolution digital fluorescence microscope, which is very expensive However, . Therefore, any clinic that can make use of this technology is likely to be able to afford more appropriate dedicated computing hardware than the XO. --Ben Schwartz ______________________________________________________________________ This inbound email has been scanned by the MessageLabs Email Security System. ______________________________________________________________________ Confidentiality Notice: This e-mail, including all attachments is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
