Reading between the lines and with a healthy dose of cynicism and probability, what is "really" on this laptop is enough irreplaceable data that if not recovered, it will significantly impact and possibly even ruin this researcher's career. Odds are good there's at least one grant with now-unattainable expectations/deadlines. There is a small but finite chance that losing it might actually set a cure of one sort or another back, but, sadly, a much larger chance that it won't help a cure and never would have. Most cancer research doesn't advance the cure dramatically at one stroke, or it would be cured, after all.

(I'm not saying research is worthless. I'm saying that, on the whole, plink a random study and all the research behind done for it and the world won't be very different on the whole. The whole matters more than the parts.)

Still worth $1000 to get it back, for both the data and the career.
