| Posted: 20 Mar 2020 04:00 AM PDT Hi Reddit! We are two behavioral ecologists who study the evolution, diversity, and function of animal weapons! Weapons such as elk antlers, beetle horns, and crab claws are fascinating (and badass) structures that puzzle us because of their extravagant sizes, shapes and colors. In the broadest sense, we use a combination of observational, experimental, and theoretical studies, to understand everything and anything that relates to animal weapons.
Although we both spend most of our time working with animals that are easy to catch and study, we recently studied one of the most charismatic animals in nature: the narwhal. Narwhal tusks are perhaps one of the most bizarre traits that exist today. Why bizarre? Well, the tusk is actually a modified tooth that can grow up to 8ft in length and protrudes from the head of male narwhals (females rarely have them). So, you can imagine how it would feel to walk about doing your daily business with a pool stick sticking off the top of your head. Despite being bizarre, little is known what the narwhal tusk is used for. Some researchers suggest that the tusk is a hunting tool, while others suggest it is a weapon used during fights. Dozens of hypothesis regarding the function of the tusk have been proposed. In our study, we examined the growth and variation of 245 male narwhal tusks to gain insights on this mysterious structure. We found that that the largest male narwhals have disproportionately long tusks, and that there was immense variation in tusk length within males. These trends align with what would be expected of a structure that has sexual functions, whether it be as a weapon use in male combat, or a signal used in female choice (or both). Furthermore, we know that male narwhals often have a lot of scars on their heads, which may have resulted from "tusking" behavior, where two male narwhals will display and cross their tusk. This study is just one example of how we both try to learn about animals and their unique weaponry. So, if you are interested in learning about animal weapons, fighting behavior, and narwhal tusks, join us at 14:00 PST (17:00 EST, 21:00 UTC), and will try to answer as many questions as possible!

| Did corals exist in prehistoric oceans? If not what filled their ecological niche Posted: 20 Mar 2020 02:09 AM PDT Was watching our planet and sir David said that if ocean temperatures rose even a degree corals expel their zooxanthellae, bleach and eventually die. Which then got me thinking, if coral is so fragile and we know the earth has had way warmer and way colder periods then how did corals survive or evolve. and were there even corals existing during most of the paleocene and if not why is their existance so crucial to our oceans health if they didn't exist before?

| (Why) do pathogens generally survive longer on metallic/hard surfaces? Posted: 19 Mar 2020 03:24 PM PDT A physics professor of mine once said there's a reason why hospitals, kitchens, and bathrooms use hard surfaces: because pathogens struggle to survive there, especially metallic surfaces. Amid the covid-19 outbreak, some cursory googling suggested contrary information (i.e. typically coronaviruses live up to 9 days on metallic/hard surfaces). I'm curious if there's a general medical consensus on this. Are hard surfaces more about easier cleaning or is there some property of non-porous and metallic surfaces that help destroy viruses?

| Why are elements like iron clustered in the ground, rather than distributed randomly? Posted: 19 Mar 2020 10:35 AM PDT My friend just said: "Isn't is crazy that wood just.. grows? It's so hard! And metal kinda grows too. What's up with that?" He's sober as a bird, for the record. But it does bring up an interesting question: Why is it that an element like iron, lead, or gems like garnet, or whatever else, commonly show up together, in clusters in the ground? For products of organic matter, like oil, it makes sense that it would be in one place. But my understanding is that atoms of iron, lead, or carbon are created in explosive fusion, and this mess gets pulled back together via gravity into hot, hot planets. So why aren't planets just uniform solutions of elements? When everything is soupy, do elements like to hang out together? I hope I've made my question clear, but I'm happy to offer clarifications if needed. [link] [comments]  |

| [[Medicine]] How do tests for viruses works? Posted: 19 Mar 2020 03:55 PM PDT I mean, lets say I get tested for influenza or Corona, what does the test do? What it does look for? And what's a positive regarding this tests? Thanks beforehand [link] [comments]  |

| How long is someone infectious after recovery from Covid-19 symptoms? Posted: 19 Mar 2020 07:29 AM PDT I haven't been able to find any data for this, does it exist? I'm thinking particularly for mild symptoms. [link] [comments]  |
| Is there a 'Naxalone' drug for alcohol overdoses? Posted: 19 Mar 2020 11:06 AM PDT Basically wondering if there's a drug doctors administer to patients that have severe alcohol poisoning, kind of like Naxalone, before hooking them up to the usual IU's and stuff. If it exists, is this a prescription drug or is it something individuals can carry on hand in case of emergencies? [link] [comments]  |
