| Posted: 24 Jun 2020 06:04 PM PDT Possibly a related question: Why is it that humans are able to produce offspring with "fresh" DNA, yet we are unable to maintain the integrity of our own DNA over time? [link] [comments]  |
| Posted: 25 Jun 2020 07:58 AM PDT How does that work? How do some trees live for thousands of years and not die of old age? [link] [comments]  |

| Are moons always smaller than the planets they orbit? Posted: 25 Jun 2020 02:42 AM PDT Could there be a planet the size of earth with a moon the size of Jupiter orbiting it? Is it a matter of density or size? [link] [comments]  |
| Could CRISPR be applied as a cure for viruses? Posted: 25 Jun 2020 04:29 AM PDT If bacteria uses it as a defence against viruses couldn't humans do it as well? Could it be the long awaited cure for viruses? [link] [comments]  |
| How seseriously is Bret Weinstein's Reserve Capacity Hypotheses taken by the scientific community? Posted: 25 Jun 2020 08:15 AM PDT In his recent appearance on the Joe Rogan Experience, Bret Weinstein brought up his Reserve Capacity Hypotheses which, roughly said, implies that a particular strain of lab mice that are used for testing pharmaceuticals have been inadvertently bred with abnormally long telomeres. And that this, in practice, leads to unreliable data on toxicity when testing human pharmaceuticals on those mice. I'd previously read his paper, and it made some sense, and felt that it was at least worth considering, given the implications. But the way that Weinstein spoke on that program set off all of my conspiracy theorists alarms. ...as is tradition with anyone that gets within six feet of Rogan. So, how credible is his claim and how seriously is it taken by the scientific community? [link] [comments]  |
| Why have the recent protests across the US not resulted in spikes in coronavirus cases? Posted: 24 Jun 2020 10:04 AM PDT Recently COVID-19 cases have been surging upward across the US, especially in the South and West, with the causes being attributed to reopening of the economy, and the Memorial day weekend gatherings. However no major outbreaks have been linked to the massive protests that have occured in cities across the country, despite public health experts warnings about large gatherings of people yelling, chanting, and coughing (from tear gas or pepper spray). How did this happen? [link] [comments]  |
| Do we update latitudes and longitudes to account for plate tectonics? Posted: 24 Jun 2020 01:45 PM PDT I just watched a documentary about the Yellowstone hotspot, and it said that the US in that region is moving to the SW at about one inch/year. That would be about 1m in 40 years, which is enough to mess up navigation. How do we account for that? [link] [comments]  |
| Do the memories of people with anterograde amnesia degrade over time? Posted: 25 Jun 2020 09:04 AM PDT People with anterograde amnesia are unable to create new memories, so apparently every time they wake up, it's the same day over and over again (essentially). So the last thing they would remember would be the final memories before being afflicted with anterograde amnesia. Do those final memories "age"? As time goes on, do those memories feel more distant? Or does it always feel like they just happened? [link] [comments]  |
| Posted: 24 Jun 2020 10:14 PM PDT This thought popped up as a response to the common saying that humans drink the same water that the dinosaurs once did. As much as there are a bunch of water molecules that do get recycled like this, it begs the question whether some water molecules simply are too deep down and under so high pressure that they never get the chance to emerge and be incorporated into the water system known by land beings.

| What happens to your brain as you're waking up? Posted: 24 Jun 2020 06:28 PM PDT When I wake up out of a dream, it takes me about an hour regain my faculties. I'm groggy, thinking is unclear, and I remember random scenes from my dream, which rapidly fade from memory. What's happening to my brain during this period? [link] [comments]  |

| How do we know the magnitude of historical earthquakes? Posted: 24 Jun 2020 07:15 PM PDT I'm reading Nate Silver's book The Signal and the Noise and he has a chapter on earthquake forecasting. In it he talks a lot about historical earthquakes, sometimes from centuries ago. For example he talks about a series of 8.1-8.3 magnitude earthquakes that hit the New Madrid Fault over a period of a few months in 1811-1812. How is the magnitude of an earthquake that happened two centuries ago determined? [link] [comments]  |

| What is the method by which our body’s acclimate to taste and smell? Posted: 24 Jun 2020 03:25 PM PDT Why do I initially smell my air freshener then it goes away, but if I leave and return I smell it again? Is it that the sensors ability becomes saturated, or does our brain receive all the signals and just filter some out? [link] [comments]  |
| Why aren’t nasal vaccines more widespread? Posted: 24 Jun 2020 11:07 AM PDT |
| Posted: 24 Jun 2020 07:58 PM PDT I've heard that the strength of immunity to a disease can vary between the two. In a recent debate, I've had someone assert that immunity developed from contracting the disease will always be stronger than immunity from getting a vaccine. I was highly skeptical, but didn't have the domain knowledge to argue it, so here I am. [link] [comments]  |
| Posted: 24 Jun 2020 05:13 PM PDT Looking at boiling point graphs, hydrogen bonded substances have a significantly greater B.P than similar molecules with no hydrogen bonding. Furthermore, molecules with an electronegativity difference very close to the limit of hydrogen bonding show very different behaviours. What is special about it, and why is the distinction from dipole dipole bonding? [link] [comments]  |
| Do van der Waals forces include or exclude dipole-dipole forces? Posted: 24 Jun 2020 11:02 PM PDT I searched online and found 2 conflicting definitions on numerous websites: 1) Dipole-dipole forces are a type of van der Waals force. 2) van der Waals forces and dipole-dipole forces are separate, with the former only referring to London dispersion forces. Does anyone know which one is correct? [link] [comments]  |
| What determines gendered voice differences? Posted: 24 Jun 2020 06:26 PM PDT Men and women tend to sound different. To what degree is this the result of social conditioning, and conversely, how much of this is dictated by physiology? Also, how consistent are gendered voice differences from culture to culture?
