- What kind of diet would we need to not have to practice dental hygiene such as brushing teeth or flossing? Are we biologically "intended" to eat this diet?
- Hi guys, so there is a comet Neowise flying past the earth right now. My question is how can a comet be visible for 2 weeks ?! Won't it just be visible for a day or two and just fly away. How can a comet be "flying by" for two weeks ?!

| Is there a natural reference for the correct time, down to the milliseconds? Posted: 20 Jul 2020 10:49 PM PDT If all our time-keeping devices shut down, how do we reset them again to the correct time? What defines the correct time in absolute term? [link] [comments]  |

| Do toothed wales digest bones, if they eat seals? Posted: 21 Jul 2020 02:50 AM PDT Do toothed wales digest the bones of the seals they eat? How do they get rid of the bones? Do they have just much stronger acids in their stomach? [link] [comments]  |

| Why do all the planets orbit along the same plane? Posted: 20 Jul 2020 11:42 PM PDT Every model I've seen of planets has them orbiting the sun along the same plane like a Frisbee. Same thing for the milky way, is everything along the same plane? [link] [comments]  |
| Why is COVID non-response (asymptomatic) considered a problem for elders? Posted: 21 Jul 2020 08:16 AM PDT I was reading this article in National Geographic, when I came across this quote that I am finding confusing, "...a range of immune responses to COVID-19, independent of age, including one that was essentially a non-response. That lack of response among some older people in the study 'could be linked to immunosenescence,' speculates Michael Betts, an immunologist at the University of Pennsylvania's Perelman School of Medicine..." I understand that means that a vaccine will not be as effective in elders, but wouldn't non-responders be fine, and not necessarily need a vaccine anyway? Because they may be infected but have no symptoms - they'd need to be quarantined until the infection period passes, of course, so as not to spread to others; but otherwise, wouldn't they survive and be just fine? Sorry if this is basic - not a biology major, not a doctor :-) *edited: changed "the" to "a" twice [link] [comments]  |

| How do you get one virus to display parts of another virus? Posted: 20 Jul 2020 07:41 PM PDT I read that the Oxford vaccine for SARS-COV-2 used an adenoviral vector expressing the spike protein of SARS-COV-2. How do scientists get one virus to express the spike protein of another? [link] [comments]  |
| Posted: 20 Jul 2020 06:00 PM PDT To further expand on the question, it's my understanding that some COVID-19 patients may experience a cytokine storm, where the immune response gets out of hand. Since a vaccine elicits an immune response, would there be a risk of it also causing a cytokine storm, either from the vaccine itself or if the person is subsequently exposed to the virus? Or is there something in the vaccines that would prevent this from happening? [link] [comments]  |

| Why are so many flowers yellow? Posted: 20 Jul 2020 12:38 PM PDT So many wild flowers that I see growing are yellow! I was wondering if there was a reason such as that color collects more light or somethin??? [link] [comments]  |
