| Posted: 14 Apr 2020 04:00 AM PDT Hi Reddit, I'm Dr. Hans Sues. I am a vertebrate paleontologist who is particularly interested in late Paleozoic and Mesozoic vertebrates. I first became interested in fossils when I was four years old and, as a high-school student, started collecting animal and plant fossils with a group of amateur collectors. Later I studied earth sciences and zoology and received my Ph.D. in biology. I have worked as a university professor and curator for many years. I am now Senior Scientist in the Department of Paleobiology at the Smithsonian's National Museum of Natural History. My field research has taken me to many countries around the world. I have done a lot of blogging and a recent series of videos called "The Doctor Is In" about fossils for general audiences. I look forward to talking with you! I will begin answering questions at 12 noon Eastern Time (16:00 UTC). Username: MESOZOICGUY [link] [comments]  |

| Posted: 13 Apr 2020 02:25 PM PDT i'm trying to develop a novel use for monoclonal antibody therapy and want to understand the possible side effects of treating somebody whose body has already endured and antigenic substance and produces natural antibodies against it. [link] [comments]  |
| Can cats catch the new coronavirus? Posted: 14 Apr 2020 06:07 AM PDT I saw some news of a tiger in a zoo that showed up with covid-19. I have no idea why someone wouldn't keep social distance of a tiger, but it happened. Was it a unique event, specific of that tiger? Maybe its immune system wasn't ok. Does it mean that other felines can catch the disease as well? For example, our common domestic cat? [link] [comments]  |
| Why does the genome for SARS-COv-2 ends in a plethora of adenine? Posted: 13 Apr 2020 12:01 PM PDT Here is the genome: https://www.ncbi.nlm.nih.gov/nuccore/NC_045512 [link] [comments]  |

| How does the Earth dissipate heat? Posted: 14 Apr 2020 08:12 AM PDT The sun is constantly warming the sun. I have a basic understanding of thermodynamics, and I can't seem to figure out how the Earth is able to dissipate all the energy it collects from the sun. It has to somehow, otherwise we'd just continue to heat up. Heat doesn't travel through a vacuum, so where does all that energy go? I recall reading that this is also a problem with the ISS and a potential problem for any future long-term space mission. So how does the Earth handle this? Thanks in advance. [link] [comments]  |

| Posted: 14 Apr 2020 07:20 AM PDT For example, do we know if someone who normally sits at 96°F would have a different chance of getting sick than someone usually at 99°F? I know there are many factors that go into immunity, I was just wondering if someone's natural body temp has something to do with it? [link] [comments]  |
| Posted: 13 Apr 2020 09:48 PM PDT I'm sure this might be unfeasible, but in theory? Give those vulnerable to the virus passive immunity, once every 1-3 months, until a treatment is found? [link] [comments]  |
| How did we know about planets before telescope? Posted: 14 Apr 2020 05:52 AM PDT How did we know that planets are different from stars before we could see them? [link] [comments]  |
| How are scientists projecting "peaks" of death/infections? Posted: 13 Apr 2020 04:31 PM PDT I'm keep hearing how scientists have projected a time period in which the peak of this pandemic takes place. How? What factor do they account for which suddenly makes it drop? [link] [comments]  |
| Wavelength manipulation...is it possible? and questions about electrons Posted: 14 Apr 2020 03:46 AM PDT Lockdown got me thinking about this. Is it possible to manipulate a wavelength. If the colour of an object is denoted by wavelength interaction between photons and electrons it got me thinking can this be manipulated. After researching about it, it then lead me to thinking about how electrons get excited - light or collision - is there a maximum amount of light that electrons can absorb? What happens if an electron stays excited? [link] [comments]  |
| Are there any diseases for which a vaccine exists but humanity isn't trying for herd immunity? Posted: 13 Apr 2020 03:15 PM PDT I have a reasonable knowledge of disease vectors, vaccines and the concept of herd immunity to protect those who cannot be vaccinated. Some people don't want any or some vaccines from a principle of bodily autonomy and I understand that viewpoint, even if I don't agree with it. Are there any diseases where this is a reasonable position to take? Are there any diseases where it isn't practical to go for herd immunity? Please don't gum up this thread with anti-anti-vaxx stuff. That's not what I'm asking. This is an academic question about disease eradication. [link] [comments]  |

| Posted: 13 Apr 2020 04:55 PM PDT I've never had the flu. I've also never had the flu vaccine, and I work in a hospital so I don't think I'm just 'lucky'. So how would getting the flu vaccine help reduce the chance of transmission? I would think the likelihood of transmission would be the same for someone with or without the vaccine?

| Except as carriers, are mosquitoes deadly? Posted: 13 Apr 2020 05:05 PM PDT What if my whole body was covered with mosquitoes and they were sucking my blood. Will it be enough to drain me out or kill me? [link] [comments]  |
| Do local geographical factors impact thunderstorm intensity or lightning strike frequency? Posted: 13 Apr 2020 10:53 AM PDT From pure casual observation, it seems that certain areas within a 50-mile radius of where I live tend to be impacted by thunderstorms more strongly than others. Is that possibly correct, or is it random? The only info I can find so far is on broad large regional differences, not local variations. [link] [comments]  |
| Posted: 13 Apr 2020 12:48 PM PDT I play video games regularly with a group of 3-5 players in a 4 player multiplayer game. We want to develop a ranking system over time that fairly reflects our performance given the fact that sometimes we have 3 players, sometimes 4, and sometimes 5, with 4 people per round and the loser rotating out. We're thinking something like an average ordinal place, except we don't want 1st out of 3 to be worth the same as 1st out of 4 (as one example). This seems like a straightforward mathematical problem but I'm having trouble wrapping my mind around any provably optimal solution. Any help would be greatly appreciated!
