| Can prions from contaminated meat remain on cutlery, dishes, pans etc, after contact with them? Posted: 08 Jan 2022 08:17 AM PST I read that iatrogenic cjd can be transmitted through contaminated surgical instruments after contact with contaminated tissue, so can variant cjd be transmitted in this way, but through the kitchen utensils that were used to cook this meat? For example, if contaminated meat is cooked in a frying pan, and later normal meat (or any other food) is cooked in the same frying pan, will this normal meat get infected through the frying pan? Will prions from the contaminated meat remain on it? [link] [comments] |

| How can gravity escape a black hole? Posted: 08 Jan 2022 02:02 AM PST If gravity isn't instant, how can it escape an event horizon if the space-time is bent in a way that there's no path from the inside the event horizon to the outside? [link] [comments] |
| Why is Covid testing so much easier than a year ago? Posted: 08 Jan 2022 06:39 PM PST Originally to get tested you had to stick the swab like 2 inches into your nose. Now you can just swab around the opening. Has tests gotten better, or were we just not great at understanding how Covid works so sticking it really far up you nose was a cautious measure to ensure accuracy. [link] [comments] |

| Why does fallen fruit begin to grow mold while fruit still attached to the tree does not? Posted: 07 Jan 2022 04:06 PM PST My guess is that the tree as some form of defense against fungi but I am at a loss to what mechanisms make up that defense. [link] [comments] |

| How do we age living trees without cutting them down? Posted: 08 Jan 2022 10:35 AM PST I'm curious on this, as the two forms of dating I know are tree rings, which require it to be cut down, and carbon dating, but as they're still alive I'm not sure this would work. [link] [comments] |

| How can B2H6 form even when boron has only 3 valence electrons? Posted: 08 Jan 2022 07:50 AM PST I was studying chemistry when I read this. It said something like terminal hydrogen and bridge hydrogen and "Banana" bond. But I wasn't able to understand. [link] [comments] |

| Is energy conserved in the redshift of cosmic microwave background (CMB) radiation? Posted: 07 Jan 2022 05:45 PM PST If I understood correctly, the CMB originated at a time when the universe was much hotter and denser than today, and originally consisted of photons of much shorter wavelength than today. As the universe expanded and cooled, the photons comprising this background radiation did too, and at present it appears to us in the microwave range of wavelengths. I don't understand how the law of conservation of energy holds for the total amount of energy carried by the CMB. The number of photons comprising the CMB can't increase. It can only remain the same or decrease (some photons will get absorbed by matter), and their wavelength is continually increasing. The total amount of energy carried by the CMB should therefore decrease (photons will longer wavelengths have less energy). If energy is conserved, where did this energy go? [link] [comments] |
| What might cause the creation of many waterfalls (in a hypothetical world)? Posted: 08 Jan 2022 03:33 AM PST Just theoretically, what properties would an ecosystem/planet need to have for the creation of a large number of waterfalls? Say, more than Earth has. I know waterfalls are created by soft rock eroding next to hard rock under a water current, but how might this scenario be naturally achieved on a grander scale? [link] [comments] |
| Heat seeking technology: how does it work? Posted: 08 Jan 2022 01:49 AM PST Is there a certain tracking distance this technology is limited by? For instance, heat seeking missiles: do they operate off of infrared light and gps, locating the target first by infrared, then tracking its path by coordinate displacement? [link] [comments] |
| Where in the sky will Sol (our sun) be in 100 years? Posted: 08 Jan 2022 08:34 AM PST If we take into account local motion among nearby stars, rotation around the Milky Way, and movement of the Milky Way itself, where would I look in the sky to see the future path of our sun (and us)?
