| Do dyslexics have issues with all symbols, or just letters? Posted: 17 Feb 2016 08:17 PM PST If a person with dyslexia saw a Chevy logo or the batman symbol, is there a chance that it would be flipped around? [link] [comments]  |

| Do you need both a -10 and -35 sequence for a promoter to bind? Posted: 17 Feb 2016 08:05 PM PST Just a bit of background. I have a DNA sequence I am trying to interpret and there is a -10 sequence for RpoD (regulatory gene regulator) and there is no -35 sequence that matches a promoter for RpoD. However, at the -17 position I have a sequence that matches AlgT (sigma factor/transcription factor) and a promoter sequence at -42. Is it possible for the RpoD to only bind at the -10 sequence and initiate transcription? Is it possible for AlgT to initiate transcription even if it is 17 nucleotides downstream of the promoter?

| Why can or can't I move differentials around an equation? Posted: 17 Feb 2016 04:19 PM PST I am currently working towards a bachelor's in mechanical engineering and I was wondering about calculus differentials. Quite often in class, we move them around freely and a professor will say something along the lines of "If you are a mathematics major, this probably makes you cringe. Technically you can't move differentials around but we can in this field." (physics or engineering) So basically my question is why is it that you cannot technically move them around, yet I do it all the time when solving problems? [link] [comments]  |

| Posted: 17 Feb 2016 06:54 PM PST It seems to me to be a great jump to postulate the existence of a new type of matter in response to astrophysical observations not lining up with predictions as dictated by current theory. Would not the more parsimonious response be to work on modifying the theory? Do we really need dark matter to explain our observations? [link] [comments]  |
| How do red/green ganglion cells detect red? Posted: 17 Feb 2016 08:54 PM PST I'm studying neuropsych and reading about trichromatic theory. I undesrstand that a green signal is sent from the ganglion cell if the dominant stimulus it recieves is from M rather than L cone cells. Because M cones are stimulated by around 530nm light, which corresponds to green light on the wavelength spectrum. But a red signal is triggered by stimulus from L cone cells, which respond to 560nm light..... but that's yellow?? Is my textbook wrong, shouldn't L cones respond to red light, such as 680nm? If not, how does the eye detect red light? [link] [comments]  |
| What is the probability of one target being hit by a ball? Posted: 18 Feb 2016 06:08 AM PST Suppose I have 4 targets. I can throw a ball four times. The ball hits one random target every time I throw it. What is the probability of the ball hitting the first target at least once? One of my classmates says that the probability is 100%, but everyone else disagrees. What's the correct solution? EDIT: The targets are reusable; they can be hit more than once. [link] [comments]  |
| Why do we always try to stop the swelling that occurs upon spraining or breaking a bone? Posted: 17 Feb 2016 04:57 PM PST Also, if it is so detrimental to recovery, why does the body do it? [link] [comments]  |
| I find entropy to be an interesting concept, but why do we research it? Why is it significant? Posted: 17 Feb 2016 06:39 PM PST I remember learning about it back in 1st year chem, but I never really grasped why it is important. To me it just seems like a cool theoretical concept, and I feel like I am missing something. [link] [comments]  |
| Posted: 17 Feb 2016 08:38 PM PST So I'm sure I saw this in a movie once. A guy breaks into a company / data centre and need some info / passwords that are on the computer. He steals the RAM because the data is stored unencrypted in memory. However because the RAM is volatile, it will loose the information if the power is disconnected. To compensate for this, he uses a spray can of some gas (maybe freon?) to freeze the RAM. This gives him a few minutes to pull the RAM out of the machine and get out of the building and re-energise it in a computer, before the RAM loses the data. Is there any validity to this?

| Are there any effects of brain hemisphere lateralization? Posted: 17 Feb 2016 08:33 PM PST I read this in my consumer behavior textbook. http://imgur.com/U4ZDEFR Is the information accurate? Does brain lateralization have any effects on behavior? I am weary to believe anything of brain lateralization after learning that left/right brain personality theory is not necessarily true.

| Half life period of radioactive substance? Posted: 18 Feb 2016 03:59 AM PST I know that half life period is the the time required for a substance to decay half of it's initial amount.My question is that many radioactive element have a huge life time in order of billion years.so how some atoms of the radioactive substance stays without decaying for such a long time. radioactive elements are unstable and and gain stability by decay process so why not every atom decay as fast as possible. I also don't understand concept of probability in radioactive decay. [link] [comments]  |

| How come this dude can carry highly enriched Uranium 235? Posted: 17 Feb 2016 05:54 PM PST Was reading this article on wikipedia[1] and got confused because some guy is holding some "highly enriched uranium 235" with only rubber gloves. If it isn't really hot, then how is this uranium used to produce heat for nuclear reactors? [link] [comments]  |
| In beta positive decay, isn't mass created? Posted: 17 Feb 2016 03:51 PM PST In the process, a proton decays into a neutron, which has more mass than a proton, a positron, which has mass, and an electron neutrino, which has mass. Therefore, although things like charge and lepton number are conserved, mass is not. What is going on? [link] [comments]  |

| Can electricity be used to convert ADP to ATP in the presence of excess inorganic phosphates? Posted: 17 Feb 2016 12:54 PM PST Sorry if the question is phrased improperly, but after doing some reading about oxidative phosphorylation it (perhaps incorrectly) occurred to me that the electron transfer chain that fuels the conversion of ADP to ATP is comparable to electricity. Could actual electrical current be used to fuel the same process? Again, my apologies if the question is phrased poorly. [link] [comments]  |
