| What is the highest temperature any solid material/element can take without changing states? Posted: 21 Jun 2022 10:22 PM PDT Im not talking just melting point either. Sublimation too. I know tungsten has the highest known melting point of any pure element at 3695 K, but I read somewhere that there are also other alloys that can take hotter temperature. I know carbon sublimes at around 4098 K so i'm wondering if there is anything that can go beyond those temperatures without a phase transition. Compounds are allowed too. Edit: Under earth's atmospheric pressure at sea level. [link] [comments] |
| Posted: 21 Jun 2022 03:27 PM PDT Let's say if i have a piece of glass or transparent medium that goes through space with a speed higher than the phase velocity and light reaces the medium from the back, can it go through, is it reflected or is absorbed? [link] [comments] |
| Why are there so many different types of venoms? Posted: 21 Jun 2022 09:47 PM PDT For example, there are different types of snakes. Of the venomous ones, how did their venoms go about evolving in potency and effects? [link] [comments] |
| Is there any way to teach the immune system to not attack an implant? Posted: 21 Jun 2022 05:29 PM PDT As in convince the system to treat or even see the implant as 'self' or at least a new part of 'self'? [link] [comments] |

| Posted: 20 Jun 2022 06:03 PM PDT It is said the massive "Carrington Event" solar storm of 1859 was so powerful it caused telegraph stations to catch fire. https://en.wikipedia.org/wiki/Carrington_Event If a coronal mass ejection of equal or greater strength were to hit Earth today, what kind of effects would it have across the globe?

| Posted: 20 Jun 2022 07:39 PM PDT Asking for a friend. Google was no help. Friend has an oat allergy that manifest as eczema, and sometimes (not all times) they break out when eating eggs or chicken or other meat. Could they be affected if the animal ate oats? They put this question to me, and I thought it might be okay to ask here. I am interested to learn if there is some sort of nutritional pass-along that comes from the food that the animals eat.

| How did the middle stages of evolution occur? Posted: 20 Jun 2022 08:06 PM PDT At one end of development we know that amino acids can form spontaneously. Peptides aren't that much of a stretch after that. At the other extreme, the strongest produce more offspring and the genes multiply. How did we get from peptides to a self-reproducing code that leads to the production of peptides that make more copies of the original code? Has anyone proposed intermediate complexity structures and then organisms that would then lead to simple single cell organisms? [link] [comments] |
