| What are Parrots trying to achieve by mimicking sounds they hear? Posted: 06 Apr 2022 07:08 AM PDT Don't know how much Animal Behaviour fits this subreddit, but I think it is a scientific question nonetheless. I like watching videos of domestic parrots making dozens of different sounds, and sometimes it's hard to think they're being made at random. When a parrot mimics a sound, what are they trying to achieve? Are they trying to convey different things with different sounds? Are they learning what responses each sound they make may elicit in other individuals? Are they simply being playful, and enjoy reproducing some sounds they hear when stimulated? [link] [comments] |

| Ask Anything Wednesday - Engineering, Mathematics, Computer Science Posted: 06 Apr 2022 07:00 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] |

| Are there any bacteria that digest methane and produce fragrances? Posted: 05 Apr 2022 11:28 PM PDT So I'm pretty aware of bacteria that digests methane and produce biofuels, but I would have to imagine that if it was possible to culture a bacteria that can produce non-carcinogenic fragrances as a byproduct, it would effectively be self-feeding if it was placed in a frequently used bathroom. My question thus, is do they exist? [link] [comments] |
| Posted: 05 Apr 2022 04:11 PM PDT Moderna is now in phase 2 of their omicron booster shot. https://www.clinicaltrialsarena.com/news/moderna-omicron-specific-booster/ No word on Pfizer. But why the wait? Why not just submit for an EUA right away? Is the vaccine that different that it would need much data to support it? Will this be the process for every variant of concern that comes out? Cause if so, it's gonna be unsustainable. [link] [comments] |
| Does the length of sleep affect the perceived length of dreams? Posted: 05 Apr 2022 06:23 AM PDT Time in dreams is a bit scooty, but I'm sure it's a pretty common experience that we sometimes have dreams which seem to go on for much longer than others. Is this at all related to the amount of time we're asleep? Can we have dreams which feel like they're longer than the time we actually slept for? [link] [comments] |
| How do you determine the age of living plants that aren’t trees? Posted: 04 Apr 2022 08:30 PM PDT We recently visited Namibia , where the Welwitschia grows. Supposedly to ages of >2000 years. How would they establish this for a living example? It doesn't have a stem where you could count rings. [link] [comments] |
| What equipment and software would be needed to map topography? Posted: 06 Apr 2022 11:41 AM PDT How could you map out the microtopography of test sites in wetlands as the hummocks and hollows relate to vegetation growth. I have zero background in surveying, ground mapping, etc. Some sites would have heavy vegetation and some sites may be inundated by water at times throughout the field season. Any help or advice would be greatly appreciated! [link] [comments] |
| Is it possible to distinguish forged steel from rolled steel by microstructure? Posted: 05 Apr 2022 02:12 PM PDT What is your opinion on how this steel was produced according to the microstructure? It seems to me that this is more like forging than rolling, do you agree? Steel microstructure https://imgur.com/gallery/teViOVg [link] [comments] |
| Why does hypotension cause nausea? Posted: 05 Apr 2022 12:09 PM PDT I was wondering what is the mechanism in which low blood pressure causes nausea? Is it a physiologically relevant mechanism or just a byproduct? [link] [comments] |
| How are bacteria-derived products produced at scale? Posted: 05 Apr 2022 11:08 AM PDT There are a lot of products, (probiotic supplements, drain cleaners, powder agricultural soil amendments), that describe the number of Colony Forming Units they contain. But how are these mass produced? Is that way off the mark? Overly reductive? Or missing some common intermediary processes? [link] [comments] |
| Posted: 05 Apr 2022 10:06 AM PDT Essentially I'm wondering if there would be a noticeable difference between different parts of a cosmic year, caused by proximity to other stars or some other factor. Is it relatively stable, in that an observer on earth would notice little to no change, or is it more significant? [link] [comments] |

| What senses do ants use to find food? Posted: 05 Apr 2022 12:27 PM PDT If there's, say, a pastry sealed in a plastic bag, can they sense the food in the plastic bag and chew through the plastic? I'm curious but also I do have ants in my kitchen please help :) [link] [comments] |
| Is there a consensus on how prescription amphetamines impacts the brain in the long term? Posted: 05 Apr 2022 12:13 AM PDT Is there good research on the long-term neurological and behavioural effects of amphetamines? I'm curious about how neurotoxic medications like dexamphetamine, lisdexamphetamine, and amphetamine are? How do they compare to other central nervous stimulants like methylphenidate? [link] [comments] |
| Does the day appear brighter in the tropics than in the higher latitudes? Posted: 05 Apr 2022 11:28 AM PDT Since the amount of light per unit area decreases as you go towards the poles, and the thickness of the atmosphere that sunlight has to pass through increases because the light is coming at an angle, does the day appear to be brighter near the equator than it is near the poles? I only have anecdotal experience when I have travelled in June (went south by about 15 degrees of latitude). The day appeared somewhat brighter down south, although that could have been because there were more bright surfaces reflecting light. But this got me thinking about insolation and angles of incidence and it would make sense that a clear day in the tropics when the sun is directly overhead would "look brighter" than a clear day in summer in a place like Belgium, which would also look brighter than a clear winter day somewhere like Sweden. I've also noticed that the days appear brighter now in April than they did in January, and I figured it has to do with the angle of insolation. [link] [comments] |

| Posted: 05 Apr 2022 07:33 PM PDT We had to do it in one of my labs for class, and I just don't really get why it's necessary to use western blotting for this. Thanks in advance [link] [comments] |
