John Holdren, Director of the Office of Science and Technology Policy, “has directed Federal agencies with more than $100M in R&D expenditures to develop plans to make the published results of federally funded research freely available to the public within one year of publication and requiring researchers to better account for and manage the digital data resulting from federally funded scientific research.”

Type 2 Diabetes Mellitus
• Affects 20 million in US, 170 million world-wide
• Leading cause of kidney failure, blindness, amputation
• Major risk factor for heart disease, stroke, birth defects
• 12% of all US health-care dollars
• Prevalence in children born after the year 2000 expected to reach 30%
• Many drugs available to elicit more insulin secretion, heighten insulin response, lower glucagon secretion
• New drugs still needed and used: DPP-4 inhibitors (2008)

Six Lessons Learned
• Sufficient data already exists to impact medicine– More is better, but we see no reason to wait for perfect data or annotations
• Even imperfect data and annotations have high utility– Requiring perfection slows secondary use
• It’s not just about infrastructure, it’s about using it– Already too many tools. Those who build tools use them first!
• Enable yourself as a scientist first, then enable others– Build and they will come… won’t work if no utility or findings
• Sticks seem to work better than carrots– Continue exponential growth, more transparency
• Need to train students to initiate science with data– High school higher education career changers
