- AskScience AMA Series: I'm Samantha Vanderslott. I research all things about vaccines and society - public attitudes/views/beliefs, developing new vaccines, government policies, and misinformation. Ask me anything!
- What would happen to hitchhiking ants?
- Why does an ion engine ionise the fuel?
- Can raccoons contract tetanus?
- Why do bees fly inside the gaps between the decoration on the exterior wall of a building and the wall?
- Why is the black hole photo so big?
- Can the amount of SARS-CoV-2 in the air be tested?
- Are kilograms relative to Earth's gravitation? Would scales work on other planets?
- Are we related to all other life or did some of it pop up independently?
- Why do black holes spiral into each other and get picked up by LIGO, instead of just orbiting each other like everything else in the universe?
- How do people find out the maximum load of bridges?
- Does water have different boiling points depending on height?
- Can a vaccine against a pathogen provide immunity if the disease created by the pathogen doesn't provide it?
- How do vaccines against Bacteria work? Such is the case with the Diptheria vaccine.
- How are stars and planets named? And why are only the planets in our solar system named after more “simple” things like gods and goddesses?
- Are there illnesses for which bloodletting actually improves a person's condition?
- Will ice fail to melt if there's no room for the water to expand?
- Could a pandemic originate in the US? Why always China?
| Posted: 03 Jul 2020 04:00 AM PDT I am a researcher at the Oxford Martin School and Oxford Vaccine Group at the University of Oxford working on health, society, and policy topics www.samanthavanderslott.com. I draw on perspectives from sociology, history, global public health, and science and technology studies (STS). I am passionate about public engagement and science communication. I have spoken on radio/TV, written media articles and am currently curating a physical and digital exhibition about the past and present of typhoid fever: www.typhoidland.org. I tweet with @SJVanders and @typhoidland. I will be on in the evening (CET; afternoon ET), ask me anything! Username: sjvanders [link] [comments]  |
| What would happen to hitchhiking ants? Posted: 02 Jul 2020 09:35 PM PDT What would happen to ants who goes up to a car and leaves someplace else? Would they die or would they join another colony? [link] [comments]  |
| Why does an ion engine ionise the fuel? Posted: 03 Jul 2020 03:36 AM PDT I know what it does but if you don't ionise it you can save a lot of power, right? [link] [comments]  |
| Can raccoons contract tetanus? Posted: 02 Jul 2020 09:07 PM PDT I work with wildlife, and I am aware that after being bitten or scratched by a raccoon a tetanus shot is recommended. I recently came across a raccoon that was stiff as a board but obviously still mentally present. I was thinking it may have had paralytic rabies, but also wondering about tetanus. Google could not give me even one resource that answers this question. [link] [comments]  |
| Posted: 02 Jul 2020 09:23 PM PDT My house has block-like plastic decorations around the windows on the exterior wall. And there are gaps between those decorations and the bricks of the building. During the summer, there are always bees looking for those gaps so they could fly into them while I rarely caught them flying out. I wonder why do they do that? What do they do inside? Is there anything I should do about this situation? I guess that maybe they want to stay in a cooler place since it's quite hot outside? However, it's also worth noting that they seem to be interested in only one particular side of one particular window since I have never seen this happening to other windows of my house. Thank you in advance for anyone trying to help!!!! [link] [comments]  |
| Why is the black hole photo so big? Posted: 02 Jul 2020 10:55 PM PDT I know this is old news but i never understood why they need petabytes of data for a blurry picture of what i can only imagine to be the aura around the black hole. Whats the deal with this thing? [link] [comments]  |
| Can the amount of SARS-CoV-2 in the air be tested? Posted: 03 Jul 2020 07:41 AM PDT I am so tired of the maskers vs. anti-maskers and how the issue has become politicized. So many people say masks don't work and to require them is asinine. The CDC currently recommends wearing them but then people point to studies like this oneon the CDC website to say that masks are ineffective. Is there a way to put someone with COVID-19 in a sterile room wearing a mask and then move that same person into an identical sterile room without a mask on to test how much the viral load in the air is in both situations? If so could thing be done with surfaces in the room such as counters? I was intrigued by Dr. Rich Davis's experiment with the agar plates but know that only showed bacteria and would like something that specifically shows that masks help with the small SARS-CoV-2 particles.

| Are kilograms relative to Earth's gravitation? Would scales work on other planets? Posted: 03 Jul 2020 06:17 AM PDT Is kilogram defined relative to Earth's gravity? Would a ~60kg object only weight ~10kg on the moon or ~20kg on Mars? If we took scales from Earth to Mars, would it still reliably measure the weight of a person (or object) in kilogram, or does it rely on Earth's gravitation? Is it even possible to make scales that work interplanetary? [link] [comments]  |
| Are we related to all other life or did some of it pop up independently? Posted: 02 Jul 2020 06:55 PM PDT I'm pretty sure I'm related to all other humans if you go far back enough, but if we went back further am I related to every duck? And even further, am I related to every oak tree? [link] [comments]  |

| Does water have different boiling points depending on height? Posted: 02 Jul 2020 11:07 PM PDT I know there are some factors that contribute to this, like purity of water. E.g: throwing salt into water so it boils later due to the ions of the salt restricting the movement on the molecules and therefore impeding it to boil by 1 °C. Also pressure. But only considering the atmospheric pressure and impliying the water is completely pure, what would be some boiling points at heights way above or below sea level? The height you choose.

| Posted: 02 Jul 2020 04:42 PM PDT If a disease cannot provide immunity, can a vaccine against the pathogen creating this disease provide it and, if yes, how? [link] [comments]  |
| How do vaccines against Bacteria work? Such is the case with the Diptheria vaccine. Posted: 02 Jul 2020 06:42 PM PDT https://en.wikipedia.org/wiki/Diphtheria_vaccine Don't vaccines only work against viruses? [link] [comments]  |

| Are there illnesses for which bloodletting actually improves a person's condition? Posted: 02 Jul 2020 11:33 AM PDT In the modern practice of medicine, are there genuine applications in which bloodletting is still regarded an effective treatment or even the most effective method of treatment?

| Will ice fail to melt if there's no room for the water to expand? Posted: 02 Jul 2020 06:29 AM PDT Let's say I fill a metal water bottle half way with ice and the other half with water. If I leave it alone sitting on my kitchen counter at room temperature, will the ice melt or will it remain solid because there's no more space for the water to go? [link] [comments]  |
| Could a pandemic originate in the US? Why always China? Posted: 02 Jul 2020 09:30 PM PDT NY and LA are very densely populated, why don't we see more pandemics starting in the US? Why do so many pandemics originate in Asia? [link] [comments]  |
