| Why do advances in animal models rarely translate to equally functional & effective therapies? Posted: 19 Feb 2019 05:38 AM PST I understand that there are fundamental differences in biology between animal models and humans. However, I don't think I have a clear answer as to what broad categories of issues might be responsible for the aforementioned failure of successes in animal models to translate to human therapeutics and I was hoping someone could explain. Enormous amounts of funding go to these therapeutic developments each year, surely someone must have discussed this discrepancy. [link] [comments]  |
| How are electromagnetic waves used to detect aircraft? Posted: 19 Feb 2019 03:22 AM PST Pretty much what the title says - I'm wondering about the way in which electromagnetics can be used to detect things such as aircraft and missiles? And what types of commonly used electromagnetic 'fields' (if this is the right term) there are? Thanks [link] [comments]  |

| does the torque required to pop a wheelie change with wheelbase? Posted: 19 Feb 2019 06:36 AM PST I know the basics of a vehicle getting front tires off the ground. Changing the weight balance and guaranteeing a lot of traction. My question is as the title says, torque. [link] [comments]  |

| Posted: 18 Feb 2019 03:42 PM PST I'm wondering if someone who lives higher up (but below the "normal" threshold for altitude sickness) has a higher tolerance than someone living at sea level. For instance, it might take the average person living at 5,000 to go up to 12,000 feet to really feel the effects instead of 8,000. Or even more interesting, would someone who lives at 1,000-2,000 feet (which is very low still) have a slightly higher tolerance vs. someone who lives at sea level? Or is it totally irrelevant and you don't start acclimatizing until 8,000 feet or so? [link] [comments]  |

| What is the sound of the "crack" of a baseball bat? Posted: 18 Feb 2019 01:45 PM PST Spring training is upon us as are the sights and sounds of baseball. One of the most recognizable sounds is the sound made when the bat makes contact with the ball. Its a great sound to anyone who loves baseball. I was curious though, what is that sound, and what is happening there? Also why the sound is slightly, for lack of a better word, different when it comes to certain players? Thanks for any help on this and continuing to count down the days until April! [link] [comments]  |

| What material to use for IR reflector? Posted: 19 Feb 2019 02:43 AM PST I need a very reflective material in the NIR-spectrum (about 850nm) but easily deformable like a plastic. I know this is not the right subreddit for it but it's the best I know and it's not against the rules. [link] [comments]  |
| Posted: 18 Feb 2019 06:57 PM PST Let's say a new dam went up, or a landslide, or some other event took away spawning grounds. Do those animals just find the nearest one to that? [link] [comments]  |

| Posted: 19 Feb 2019 01:28 AM PST We can't achieve a perpetual system due to entropy. What about something like the moon? Throughout human history, has it distanced itself in anyway from the Earth? And do satellites stay up there forever? [link] [comments]  |
