34 - immunoincompatibility :: take the human genome, and refactor it so | |
35 that it doesn't use a particular codon at all. Then remove the | |
36 support from our ribosomes for that codon. What does this do for | |
37 us? It makes us immune to almost all viruses! | |
38 | |
39 - life cycle :: it's called a cycle, right? So, the thing that repeats | |
40 itself over and over, right? Not much of a cycle if | |
41 you don't come back after you die, if you ask me! | |
42 | |
43 - car with no blind spots :: use some cameras in the back of the car | |
44 to augment the rear-view mirror so that you never have to turn | |
45 around in order to lane change. | |
46 | |
47 - partial cell death :: you freeze a set of cells using some cryo | |
48 protocol and 60% survive. How can this be explained? It seems to | |
49 me that if the cells are the same, and the conditions | |
50 homogoneous, then all the cells should either die or | |
51 live. However, suppose that there is a metabolic cycle that needs | |
52 to be in a certain phase for the cell to survive. If the cells | |
53 are asynchronous, then you might end up with some cells dying | |
54 because there were in the wrong part of their cycle. This implies | |
55 that you might be able to cryoprotect cells by causing them to | |
56 enter a certain metabolic mode before freezing. | |
57 | |
58 - cryonics color appeal :: perfusate used by cryonics companies should | |
59 have red food coloring in it. It's just a nice touch so that the | |
60 cryonics patient looks more life-like than with clear CPAs, and | |
61 hopefully might get treated with more respect. | |
62 | |
63 - paramagnetic CPA :: you take a CPA that can be influenced by | |
64 magnetic fields so that its degrees of freedom are limited. Then, | |
65 you release the field, instantaly increasing the size of the | |
66 state space of the system and dramatically decreasing the | |
67 temperature enough to plunge the system past homogenous | |
68 nucleation temperature and directly to the glass transition | |
69 temperature, creating a doubly unstable glass at much lower CPA | |
70 concentrations than possible at conventional CPA concentrations. | |
71 | |
72 - room temp noodles :: how does the physics of cooking noodles work? | |
73 Could you use a vacuum instead of heat to force water into the | |
74 noodle? | |
75 | |
76 - personal carbon offset :: feel bad about contribuiting to global | |
77 warming by using electricity / driving a car? Forget trying to | |
78 "conserve" or "minimize your carbon footprint". Follow the | |
79 Platinum rule -- make the world BETTER off than you found it! | |
80 This would be a small, self contained system that sucks C02 out | |
81 of the air. It uses electricity, but it's so efficient at | |
82 removing CO2 that it more than offsets the CO2 produced by even a | |
83 coal plant to produce that electricity. This way, you can still | |
84 drive even a gas guzzler, but have a net negative carbon | |
85 footprint! Maybe something cool could be done with the carbon as | |
86 well. Use as much electricity as you want, but negate the damage | |
87 to the enviroment with more technology. | |
88 | |
89 - undoing spermogenesis :: with enough sperm, you can derive the | |
90 donor's entire genome. You gain more confidence in the alleles | |
91 for a particular gene the more sperm you have. Each additional | |
92 sperm gives you the same sort of information you'd get flipping a | |
93 coin and trying to decide whether the coin is H/T of H/H. Is | |
94 there enough sperm in the the average load for you to be as | |
95 confident as mitosis? | |
