| Is chemotherapy better now than it was 10 years ago? Posted: 20 Jul 2021 08:58 AM PDT Is the process relatively unchanged or is it more effective / has less side effects than it would have had say 10 years ago? What might we expect it to look like in 10 years from today? [link] [comments]  |

| Why has early detection of diseases via dogs not found widespread use in medicine? Posted: 20 Jul 2021 05:41 PM PDT I have heard how dogs can detect diseases such as cancer or now covid with a surprisingly high accuracy. However I have not seen widespread use of dogs in such a manner. [link] [comments]  |

| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 21 Jul 2021 07:00 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary 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]  |
| Posted: 21 Jul 2021 06:33 AM PDT My understanding is that a B cell remembers a specific pathogen, so I am assuming most pathogens you have ever encountered have B cells made for them hanging out where they might some day be needed. Are there a limited amount of these cells (or total cells?) you can have in your body? Like, does having 30 different versions of useless common cold B cells mean that the area they hang out in is now diluted and can hold less useful B cells? [link] [comments]  |

| [ Africa Rift / EARS ] Help understanding Tanzanian Divergence, and KT Rift & Kivu Rift differences? Posted: 21 Jul 2021 02:42 AM PDT Welcome, I am interested in learning more of the science of the Rifts. Primarily the Tz Divergence of the KT Rift. Secondarily, why the differences between the KT Rift and Kivu Rift? Recently I have been spending time in Arusha and am curious about Mts Meru / Kilimanjaro relation to the KT Rift and the nature of the splintering of the KT Rift. Where does the rift end and fractures begin? I assume Ngorongoro? After much searching on Google, Wikipedia and Scihub I have learned about the Tanzanian Divergence and a large reservoir of lava under us. I feel comfortable with basic research (google/wiki) but my weeks of Scihub research I am acquiring more questions than answers. Also, interested in the differences between the KT Rift and Kivu Rift. Specifically the cause, and why they differ so much. Kivu is very clean as lakes with large volcano ranges between them. KT also has this (Natron/Ngorongoro/Eyasi) but with a lot more around it. Such as Milima Meru / Kilimanjaro, or Mt Kenya not being on the rift. I assume this has to do with the reservoir of lava and goes back to my primary question? Any reason these great Mounts are so far to the east of the KT Rift? Extra Credit: I am from between both rifts. South East of Lake Victoria. In my reading I learned we are separate from the Africa east of Ngorongoro and West of Kivu. I am unclear of the south east separation of our plate. I assume it is Mts Udzungwa? Thank you!

| What exactly is unhealthy air quality? Posted: 20 Jul 2021 07:09 PM PDT Hey what does it mean when the weather says "Unhealthy air quality for sensitive groups" and shows a number, for example here 113. What is this number referencing? How do they determine what's healthy vs not healthy air and why is it happening? [link] [comments]  |

| Why does ibuprofen reduce inflammation? Posted: 20 Jul 2021 09:51 AM PDT In specific how does it help with costochronditis? [link] [comments]  |
| What receptors mediate the taste of milk? Posted: 20 Jul 2021 09:00 AM PDT After drinking dairy milk all my life and switching to oatmilk for a few months, I now find the taste of milk repulsive. Lots of questions here focus individual variability in taste perception for certain foods. But is it known which taste receptors 'die out' when I stop drinking dairy? or does oatmilk specifically causes others to predominate? Or even something related to mouth flora? [link] [comments]  |
| Are film grain and digital noise caused by the same thing? Posted: 20 Jul 2021 08:23 AM PDT So I get that film grain is caused by larger silver particles in higher ISO films, but digital noise is also caused by high ISO. Is this just a coincidence? Not sure what to tag this with so I'll just go with physics. [link] [comments]  |
| Are there cases of rocks from Earth finding their way to Mars? Posted: 19 Jul 2021 07:54 PM PDT It is well known that Martian Meteorites frequently find their way to Earth. This is one of the ways by which we can study the geology of Mars and such rocks often contain evidence that Mars was once habitable. But does the opposite ever happen? Are there cases of rocks from Earth finding their way to other planets like Mars? Is it much rarer for such to occur due to the strength of Earth's gravity and magnetic field as well as the thickness of Earth's atmosphere compared to that of Mars? If so, what could cause such freak events to occur? If such ever occurred, and let's say the rocks happen to be carrying microscopic organisms from Earth, would they contaminate Mars once the rocks got there? [link] [comments]  |
| Were rats/ mice as ubiquitous pre-agriculture as they are now? Posted: 19 Jul 2021 05:14 PM PDT Rats, mice, "pest" animals in general really. Go to any major city at night, and you'll undoubtedly see a rat run across the street. But would pre agricultural human camps have the same sights, or were their populations naturally kept in check?
