Which of these two jobs should I take?

I have been offered two jobs and have to make a decision ASAP. Both positions are in the same city. One pays $38k and one pays $52k. The $38k position is a 6 month temporary position, but if it works out, I may be offered a supervisor position that starts out around $60k. The $52k position is a permanent position with a 5% annual pay increase, but I'm pretty much stuck in that position for at least 10 years. Both jobs have similar benefits except the $52k position's retirement plan can't be used until after 20-30 years on the job, which is fine as I won't want to relocate and it's for a university, so I could easily find another job there and continue my retirement. The $52 position is a systems analyst, but the $38k position is a high-throughput data analyst which after some experience in, could lead to a 6 figure job if I ever wanted to move to a larger pharmaceutical corporation. The systems analyst position is basically a desk job, while the high-throughput job, I would have two desks and apart from database work, I would be working with actual biological samples, chemicals, lab mice, wear a lab coat & goggles, etc. Apart from the obvious $14k difference for the first 6 months, one job has a lot more potential in the future, would be way more exciting, and also has coolness factor like working with medical marijuana. I just got out of the military and have no desire to do anything illegal or stupid, it's just a little bit of a coolness factor. In all seriousness, I know which ever position I take, I could regret in 6 months, but with the high throughput job, I may actually be a lot better off down the road. What should I do. Both positions have been offered to me.
