I understand the damage is probably cumulative over time, yet the reduction in lifespan is extreme. I find it interesting that they can survive the venom and develop the "anti-venom" to it, but they still suffer from this effect. What is the scientifical reason for this to happen and can people suffer from the same effect from spider bites, albeit in a minor form due to probably much less venom being injected?

| How do chemical reactions occur at relatively low temperatures if typical bond energies are so high? Posted: 25 Aug 2020 07:04 AM PDT My understanding is that when molecules interact with each other and form other molecules what first has to happen is that chemical bonds need to be broken before they can be reformed. Looking at various tables for the bond energies of common bonds they're usually listed in kJ/mol or eV, in the latter case being listed as several eV. My understanding is also that an energy of 1 eV is associated with a temperature of around 11,000 K. Since bonds are listed with strengths of several eV, wouldn't that mean that you'd need to heat compounds up to several tens of thousands of degrees to break them? That clearly doesn't happen in everyday scenarios or when chemists heat up samples for experiments, so what's my misunderstanding with all this? [link] [comments]  |
| How will this flu season affect the current COVID-19 situation? Posted: 24 Aug 2020 10:08 AM PDT I'm not very knowledged on how viruses work, but would the chance of mutation increase if there are other viruses present in the immune system? If so, how severe/mundane could this turn out? [link] [comments]  |

| Do sea levels fluctuate over the seasons due to water trapped in land ice? Posted: 24 Aug 2020 03:13 PM PDT My understanding is that sea ice doesn't really change that much in terms of sea level but that land ice does as water is locked up on land. Since most land is in the north, do sea levels go down in the northern winter at all and up in the northern summer? [link] [comments]  |

| Why do children not spread covid as well as adults ? Posted: 24 Aug 2020 04:46 PM PDT With schools opening up in the UK , the government are saying the science is saying, transmission rate among children is low. Why is it low for children and not adults? Why is this getting downvoted... [link] [comments]  |
| Are vaccines usually conferring sterilizing immunity? Posted: 24 Aug 2020 09:10 AM PDT I have been reading a lot about the recent development of COVID-19 vaccines and the discussion about how good it's going to protect us and I started to wonder wether vaccines usually confer sterilizing immunity or not? Is it normal to be immune but still being able to shed a virus (maybe in reduced amounts) or are vaccines normally sterilizing so you can't infect anybody after your body has developed immunity/antibodies. Is it normal to be completely not spreading anything anymore after being vaccinated or do you rather just gain immunity for yourself so you don't get sick? Wich vaccine does what specifically? I couldn't really find anything about this topic on google. Thank you very much! [link] [comments]  |
| Posted: 24 Aug 2020 04:14 AM PDT The family Felidae (cats) is split into two extant subfamilies, Pantherinae and Felinae, so I would assume that even though they are cats, members of Pantherinae would technically not be 'feline' (although they would be felids). Googling this just comes up with "feline = cat" which isn't totally clear [link] [comments]  |
| [Biology] How do animals, both mammal and non-mammal handle eating active, living prey? Posted: 24 Aug 2020 01:55 AM PDT As a human, I can't imagine eating an entire living organism whole, and NOT experience severe indigestion. What with it still alive, for a time, in my stomach wiggling about. So how do animals tolerate this? [link] [comments]  |

| How do we measure the energy released by cosmic explosions? Posted: 24 Aug 2020 02:32 AM PDT So, a friend of mine sent me a post about how there was an energy outburst by a binary collapsing, and the caption said that the energy released was equivalent to 10 trillion atom bombs or some other really crazy number like that. How do we calculate these large numbers? How accurate are they? My intuition says that we already know how much energy an ordinary atom vomits up, so we could just compare the energy released by one atom to the energy released by the stars, but this is just a guess. I would love it if you guys could explain it this to me, or just direct me towards a relevant article. [link] [comments]  |
