If working out causes micro tears in muscle and the healed tissue is where strengthening comes from could one just induce Micro tearing from a artificial source other than working out and gain benefits from it?

Can dogs tell the difference between male and female humans?

Posted: 14 Mar 2020 05:21 PM PDT

Are dogs able to distinguish if you are a male or female? My male dog tends to gravitate towards me where as my female dog loves my wife. Do they tend to pick sides?

Soap interacts with lipids. My cells are held together by lipids. How come that if I wash my hands with soap my body doesn't dissolve?

Posted: 15 Mar 2020 05:13 AM PDT

Thought about it because of some Corona virus illustration I saw on Reddit about how washing hands with soap rips apart the virus and thus helps.

Why do isotopes like deuterium and tritium fuse so easily in stars?

Posted: 14 Mar 2020 09:21 PM PDT

So I know in stars, deuterium and tritium fuse together to form helium isotopes, which generates a mass amount of energy. But what makes deuterium and tritium so prone to fusion in stars? Why not hydrogen or another atom? What chemical property or behaviour makes them so prone to fusion?

Why do people get muscle cramps seemingly at random?

Posted: 14 Mar 2020 06:57 PM PDT

I tried googling how muscle cramps work but I honestly can't find anything solid on the biological basis for why cramps occur. One paper had language like "Disturbances at various levels of the central and peripheral nervous system and skeletal muscle are likely to be involved in the mechanism of cramp and may explain the diverse range of conditions in which cramp occurs.", which to me reads like "no clue".

Bonus question: do all mammals get muscle cramps? What about insects?

Is there any good science behind Earworms?

Posted: 14 Mar 2020 02:13 PM PDT

I hear it's established psychology that an earworm (song you hear in your head) is the result of the mind not being very busy. However, what is happening when the song is the same song (or, frustratingly, the same few lines of a song) day after day after day? This considers several days of sleeping/school/work/normal daily activities, but the same song pops up. Then after a few days, that song will be gone, and not even easy to recall what it was.

So what's going on with that?

What is the rationale or correlation between pH and protein adsorbtion to plastics in microtitre plates?

Posted: 14 Mar 2020 04:36 PM PDT

Higher pH Buffers such as Tris or Sodium Bicarbonate are commonly used to Coat/Adsorb proteins to microtitre plates for ELISAs. My question is why a Higher pH is better for protein adsorbtion to (polystyrene) plastics?

Does white noise sound different for everyone??

Posted: 14 Mar 2020 11:40 AM PDT

If white noise is a combination of all frequencies of sound that humans can hear, and people hear certain frequencies more than others, does that mean white noise sounds different for other people? Do old people hear white noise as a lower "note" than young people?

What role does gravity play in creating the rings of a planet?

Posted: 14 Mar 2020 05:03 PM PDT

I watched a documentary on black holes and they showed the accrual disc and it occurred to me that it is flat and not a cloud. This doesn't really make sense to me because gravity should pull in all directions right? So the debris that makes up the disc should be coming in from everywhere.

Then I thought about Neptune and Saturn and they have rings, but again the rings are flat discs. So what is going on that makes the debris flatten out?

How old is the Atlantic meridional overturning circulation (AMOC) system?

Posted: 14 Mar 2020 03:51 PM PDT

Reading "Ocean circulation and climate during the past 120,000 years," by Rahmstorf, S. (2002), and I got to wondering if it's the same age as the Cenozoic.

Were there similar older systems in the Mesozoic? The Paleozoic?
