| Posted: 03 Jul 2019 04:00 AM PDT Hi! My name is Alicia McGrew, and I am a PhD candidate at the University of Florida. My PhD research at the University of Florida is focused on the food web that lives inside the leaves of a carnivorous pitcher plant (Sarracenia purpurea). Florida is the carnivorous plant hotspot of North America; however, this particular pitcher plant is unique, as it relies on a community of aquatic micro-organisms to help decompose its prey and acquire important nutrients for growth. I use this model food web to ask a number of questions about ecological communities: which organisms are there, how do they interact, and how does this composition and structure vary across different ecological and environmental conditions? I'm particularly interested in the role of nutrients and predation on structuring aquatic communities. I'm from Michigan, and first began doing research on aquatic communities in the Great Lakes region, where I spent many hours on a microscope! I worked as a technician to sample and identify zooplankton taxa in a variety of habitats. For my Master's research, I investigated the feeding ecology of an aquatic invasive species to the Great Lakes region, the bloody red shrimp. When I'm not doing science, my other interests include teaching, reading, gardening (including a mini pitcher plant bog!), traveling, and hiking. You can read more about the work being done at the UF/IFAS Department of Wildlife Ecology and Conservation here and here. I'll be on at noon EDT (16 UT), AMA! [link] [comments]  |

| Can Brain Training Improve Reading Speed? Posted: 03 Jul 2019 04:30 AM PDT Reading is a very complex cognitive process. It's very interesting, can brain training, for example, Lumosity games, improves reading speed? Any investigations? [link] [comments]  |
| What prevents a tower crane from toppling over? Posted: 03 Jul 2019 08:13 AM PDT I'm just astounded by the engineering marvel of cloud-breaching skyscraper construction and the assisting tower cranes that make it possible. Hoisting significantly heavy materials from ground to top level, and such a skinny build, what are the design measures that balance it? What balances the center of mass? [link] [comments]  |
| What would be the consequences of rejecting the assertion of the axiom of empty set? Posted: 03 Jul 2019 12:20 AM PDT The existence of a set that contains no elements is something I could never wrap my head around or accept. Defining nothingness seems like a contradiction and a mistake. You can only define what exists and according to naive set theory, any definable collection is a set. It seems to me that the axiom of empty set is simply an arbitrary assertion created to avoid Russell's paradox. In mathematics, a set is a collection of distinct objects, considered as an object in its own right. The concept and quality of nothingness is the very opposite of what it means to be a set. There is no quality of nothingness. It just simply isn't there. It isn't even an "It".. We give it a name so as to talk about it conceptually when I disagree we should even talk about it at all considering we aren't even talking about anything to begin with. [link] [comments]  |

| Posted: 03 Jul 2019 02:42 AM PDT I saw this post and wondered if the charge of the battery (full vs. dead) would affect the intensity of the reaction. Secondly is there any types of battery where the charge would affect this sort of reaction? [link] [comments]  |
| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 03 Jul 2019 08:13 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Engineering, Mathematics, Computer Science Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Is the ionic radius of Cu2+ bigger than Cu as an atom? If so then why? Posted: 03 Jul 2019 01:48 AM PDT I could not find any help on the internet. Any help would be very much appreciated :) [link] [comments]  |

| What would happen when a simple pendulum is taken to the centre of the Earth? Posted: 03 Jul 2019 02:52 AM PDT When the pendulum is at the center, what does infinite Time Period signify? Will there be no oscillation, or 1 oscillation in infinite time, or are both the same thing? [link] [comments]  |
| How does white vinegar get rid of odours? Posted: 03 Jul 2019 02:11 AM PDT I see vinegar recommended in a lot of places for removing odours (particularly cat pee) but how does it actually do this? [link] [comments]  |
| Posted: 03 Jul 2019 05:56 AM PDT I mean, how could it fight gravity continuously without expend any energy? [link] [comments]  |
| Does biological material encased in Amber fossilise? Posted: 02 Jul 2019 10:08 PM PDT Fossilisation replaces biological material with minerals. In Amber is the material protected and therefore potentially available for analysis? [link] [comments]  |
| What differentiates the Neogene from the Quaternary period? Posted: 02 Jul 2019 11:44 PM PDT I see that Wikipedia says that the Neogene period ended "2.588 ± 0.005 million years ago." Was there a drastic change that happened and allowed us to determine this to with such precision? [link] [comments]  |
| How does Newton's 3rd Law apply to an object falling in a vacuum? Posted: 02 Jul 2019 07:25 PM PDT For every action there's and equal, opposite reaction. If you were to drop an object, the force of gravity will be fought by air resistance in an atmosphere, but, in a vacuum where there is no air, what is the opposite reaction? [link] [comments]  |
| How far underwater do I have to go to be protected from sunburn? Posted: 02 Jul 2019 08:26 PM PDT Will a standard swimming pool's depth protect me from getting sunburned? [link] [comments]  |
| Posted: 02 Jul 2019 06:47 PM PDT So if I understand correctly light waves enter the atmosphere as infrared, visible light, and UV. Mostly the infrared waves heat up the earth and can't escape due to the greenhouse gas molecules in the atmosphere, which means the heat builds up in the Earth. If greenhouse gases block the radiation from leaving, why wouldn't they also block them from entering? [link] [comments]  |
| Does gravity act the same way on antimatter as it does on matter? Posted: 02 Jul 2019 09:41 PM PDT What is it about matter that makes it susceptible to gravitational forces? [link] [comments]  |
| What keeps the earth's axis in its position? Posted: 03 Jul 2019 12:55 AM PDT Is there anything that could cause the axis to move to a completely vertical position? (so that day and night length would be equal) [link] [comments]  |
| Posted: 02 Jul 2019 02:45 PM PDT What is the first known occurence of cancer in the animal kingdom? Can we even tell that through the fossil record? Thank you [link] [comments]  |
| Should gravity, as an abbreviated form, use capital G or lowercase g? Posted: 02 Jul 2019 08:25 PM PDT I'm an old guy and always thought it was uppercase G. But I recently came across an article on the g-force involved in the explosion of torpedoes on the Kursk, and see it all being lowercase. I am usually reading astronomy articles, as an amateur - is there a difference? [link] [comments]  |
