| Posted: 20 Jul 2016 05:00 AM PDT Hi, my name is Eric Noel Muñoz. A life-long ocean lover with a degree in physical geography from San Diego State University, I wrote about how Agua Hedionda Lagoon in northern San Diego County eradicated an invasive species of seaweed between 2000 and 2006 which was most likely released from a home aquarium. This strain of Caulerpa taxifolia (nicknamed "Killer Algae" for good reason) is a mutant genetic clone of a natural counterpart; it has no predators, keeps fish away, grows rapidly and smothers reef or rocky substrate, and reproduces via fragmentation. First detected in the Mediterranean Sea and now in over half a dozen countries there, it also is in Southern and Eastern Australian wetlands. As a Carlsbad city planner and later lagoon foundation president, I had many roles in the eradication effort and outreach efforts from 2000 through 2015. The book is a personal account which covers the issue from many angles and includes time spent in New Zealand, Australia, Croatia, France, and Monaco. Our local effort—the only known successful eradication of an invasive marine species—is put into a global context and outlines the success of our rapid response that combined funding, science, and policy. You can check out my book Caulerpa Conquest: A Biological Eradication on the California Coast on Amazon or directly from the publisher, Open Books Press. You can watch my 3-minute TED animated video here: Attack of the Killer Algae - Eric Noel Muñoz For my AMA session, I will be joined as necessary by a consulting biologist/scuba diver who was part of the eradication team, Robert Mooney, Ph.D, of Marine Taxonomic Services in San Marcos, CA. Christopher Knight, environmental activist and Peter Brady from The Brady Bunch will be on from 12:30 to 1:00 PST and can chime in on any questions about his work with community outreach regarding Caulerpa taxifolia. I look forward to your questions on everything from our efforts in California to the situation in the Mediterranean and in Australia, plus whatever else you might think up. I'll be on from noon to 2 p.m. PST. AMA! [link] [comments]  |
| Why are planets not tidally locked with the sun? Posted: 20 Jul 2016 03:40 AM PDT We only see one side of the moon because it's tidally locked with the earth. Why do other orbiting bodies not tidally lock with their centers? (i.e. planets and the sun) [link] [comments]  |
| Posted: 19 Jul 2016 09:54 PM PDT If for example, you just sit through classes with your hands on your desk and your arms in a constant flex... assuming you are determined enough not to let loose, is it possible to strengthen them this way? [link] [comments]  |
| Is 'not not and not not not' the same as 'not'? Posted: 20 Jul 2016 06:58 AM PDT Dunno if /r/asklogic exists is frequented or is populated but I was wondering; there can be 'not' and there can be 'not not' but can there also be a third of 'not not and not not not' or is the third the same as the first or second? [link] [comments]  |
| Posted: 19 Jul 2016 08:36 PM PDT And is there strong evidence to suggest the body selectively targets unfit cells for removal on these diets? A few papers I found:
And some documentaries: [link] [comments]  |
| Posted: 19 Jul 2016 08:02 PM PDT I have long thought that the redshift/blueshift stuff was light being subjected to the rigors of space over light years. If it can observably change directions, surely it can stretch or contract given the right environmental conditions IMO. What would that imply given what we know about the current size of the universe? [link] [comments]  |
| Why can't iodine (I2) be mixed with water? Posted: 20 Jul 2016 07:40 AM PDT According to the Iodine MSDS, it says iodine must never be mixed with water, i would like a simple explanation as to why it is like that. Thank you and please. Edit: Im on mobile, so I cant see flairs, sorry about that. [link] [comments]  |
| Why do we see only one side of the moon ever? Posted: 19 Jul 2016 05:37 PM PDT I know the rotational period and period of revolution for the moon are the same, but why is this the case? What caused them to be the same? [link] [comments]  |
| How is blood flow directed within the brain? Posted: 19 Jul 2016 09:47 PM PDT Neural imaging scans work by showing us how different parts of the brain get different amounts of blood flow depending on how much they're being used at the moment. So, somehow, different parts of the brain with a lot of activity get more blood, and parts with less activity get less. But ... how? How is this blood flow directed within the brain? How do different veins or arteries know to open or constrict in time to keep up with the brain's rapidly changing demands? Is there some structure in the brain that basically controls all of this, or is it somehow distributed to all the different parts, each one taking what it needs? [link] [comments]  |
| What's the longest single cell in the world? Posted: 19 Jul 2016 08:40 PM PDT I'm assuming it's probably going to be a neuron in a blue whale ... but how long is it? [link] [comments]  |
| Posted: 19 Jul 2016 01:45 PM PDT Do they have their own languages they have built? Thanks. [link] [comments]  |
| Posted: 19 Jul 2016 06:39 PM PDT I tried asking a (probably stupid) question on the AMA with the quantum researchers that was held yesterday, but I guess I was too late to the party, so here it goes: What is the difference between a particle being in a superposition of states and simply having it's current state unknown to us (but determined)? To give an example, we could theoretically create a machine that splits a ball in half, sending one half spinning clockwise and the other anticlockwise (randomly). If we find one half of the ball, we would be able to know that the other half is spinning in the opposite direction. However, I understand that those two parts of this microscopic ball aren't entangled. How different to this system are entangled particles and why? Is it related to bell's theorem (if so, I'll probably need a very simplified explanation on that)? [link] [comments]  |
| How do ALVAC and AIDSVAX work to prevent HIV infection? Posted: 20 Jul 2016 05:45 AM PDT Recently CNN published a news that a new vaccine regiment of ALVAC and AIDSVAX has managed to score a modest rate of vaccination of about 30% at the end of the trial in Thailand, and now the researchers are going to run another trial in South Africa (source: CNN). Being very curious, I looked for paper. To my disappointment, most papers give the highlight on statistical analysis, much less on the molecular virology of the vaccines. Those papers are:
If anyone could provide the molecular biology aspect of the vaccines, ALVAC and AIDSVAX, that would be extremely helpful! [link] [comments]  |

| Why does my Lifestraw (filtration system) filter out harmful bacteria, but not salty water? Posted: 19 Jul 2016 07:47 PM PDT If I was to venture a guess, it would be because the salt attaches to the H2O molecules, where bacteria does not actually bind to them. However I'm not really sure so I thought I'd ask! Thanks in advance! [link] [comments]  |

| What would it look like at the edge of the universe? Posted: 19 Jul 2016 04:37 PM PDT If the universe is expanding in all directions at the speed of light then what would it look/be like to stand at the very edge? Would you witness anything happening as the universe expanded or would it seem as if nothing new had formed or changed at all? [link] [comments]  |

| What were the treatments for Syphilis prior to antibiotics? Posted: 19 Jul 2016 07:41 PM PDT Before antibiotics, how did physicians combat syphilis? I'm particularly curious about how they did in the 19th and early 20th century. [link] [comments]  |
| Posted: 19 Jul 2016 10:20 AM PDT Let's assume that my fingers can magically grip atoms, and that I can align them with perfect precision. How much strength would it take to rip one apart or combine two atoms? How much would the required force vary for different elements to split or fuse them? Bonus question, would the energy released from the reaction be visible or perceptible to me? How much would the energy released vary from the fission or fusion or different atoms? [link] [comments]  |
| Are there cases where a common ancestor, as well as descendants, have existed simultaneously? Posted: 19 Jul 2016 07:27 PM PDT So in evolution, two species might share common ancestry. What I am wondering is if there are times where these common ancestors continue to exist after their descendants have "evolved" into their current form. If so, are there any more extreme cases, where it might have gone back many ascendants? [link] [comments]  |
| If an atom were at absolute zero, would it be possible to know both its position and velocity? Posted: 19 Jul 2016 11:48 AM PDT |
