  • Are there any good opportunities for veterinary-human crossover drug discovery?

Computer science

  • What is the minimum number of dimensions necessary to implement a universal classical computer?
  • Are computational kinetics provable? (i.e. can we determine analytically which processes cannot be computed faster on an alternative architectures without having to simulate them?)
  • Will homeomorphic encryption become practical anytime soon?
  • How probabilistic is software debugging? How much of it can be automated?

  • Can more computation be memoized than we think?


  • Do microwaves have any non-thermal effects on reaction kinetics?
  • How useful is light in imparting enantioselectivity?
  • How well can organisms discriminate isotopes?

  • Can the reverse of a microwave oven exist? I.e. “stimulated radiative cooling”.
  • Can some formal expression describe the minimal energetic costs of molecular quality control?
  • How does Shannon entropy relate to Boltzmann entropy? (I read answers to this one once in a while, but I don’t really get it yet. It seems like the most important and fundamental bit of science that I never encountered in school.)
  • Can we measure the information content of matter through calorimetry?
    • Thought experiment: I have one hard drive filled with random data and another that has 1s and 0s in strict alternation. I put them both in a perfect bomb calorimeter. Do they evolve different amounts of heat?
