- AskScience AMA Series: Hi Reddit! We are scientists from Pacific Northwest National Laboratory. We recently designed a carbon capture method that's 19% cheaper and less energy-intensive than commercial methods. Ask us anything about carbon capture!
- Covid vaccine 2nd dose?
- Is it possible for black holes to 'move' through space and, if so, what would happen if Earth came upon one?
- Can someone get immunity to covid by getting blood from a fully vaccinated blood donor?
- Is it possible that an object in space is so red or blue shifted, that it’s outside of the visible light spectrum? Are there things moving away from us so fast that we can’t see it with a typical telescope?
- What is the clear fluid that oozes from wounds?
- How is a magnetic field captured through a telescope? More specifically, how did the Event Horizon Telescope manage to capture that recent black hole image?
- This may sound stupid, but, because of the way chromosomes are passed down, how does a paternal grandmother have a genetic relationship with a grandson?
- Is it really that bad for a battery to recharge it before it’s completely empty?
- How is CPT symmetry maintained if each individual aspect of it is violated?
- Do you become contagious after getting a vaccine?
- Where in the process for formal FDA approval are any of the three COVID vaccines beyond the EUA?
- Is it particularly hard to treat rabbies or have no treatments been developed simply because the vaccine is so effective?
- Why does the pH of hydrogen fall at such a perfect integer value?
| How do the so-called nuclear shadows from Hiroshima work? Posted: 25 Mar 2021 04:24 PM PDT How could an explosion that consists of kinetic energy (might be some other type?) and thermal radiation create a physical "shadow" or imprint on the ground or on a wall? [link] [comments]  |
| Posted: 26 Mar 2021 06:39 AM PDT Hi Reddit! We're Yuan Jiang, Dave Heldebrant, and Casie Davidson from the U.S. Department of Energy's Pacific Northwest National Laboratory, and we're here to talk about carbon capture. Under DOE's Carbon Capture Program, researchers are working to both advance today's carbon capture technologies and uncover ways to reduce cost and energy requirements. We're happy to discuss capture goals, challenges, and concepts. Technologies range from aqueous amines - the water-rich solvents that run through modern, commercially available capture units - to energy-efficient membranes that filter CO2 from flue gas emitted by power plants. Our newest solvent, EEMPA, can accomplish the task for as little as $47.10 per metric ton - bringing post-combustion capture within reach of 45Q tax incentives. We'll be on at 11am pacific (2 PM ET, 16 UT), ask us anything! Username: /u/PNNL [link] [comments]  |
| Posted: 26 Mar 2021 04:32 AM PDT Is the 2nd dose of the (Pfizer or Moderna) vaccine a different formulation than the 1st? Why do people get more side effects from the 2nd dose? [link] [comments]  |

| What is the clear fluid that oozes from wounds? Posted: 26 Mar 2021 12:01 AM PDT I burned myself pretty badly a few days ago. Left wrist and two fingers through the skin. Now the wounds leak this clear fluid which will drip off if I'm moving that hand or crust up if left motionless. I'm guessing it's a reaction by the body to prevent infection by making a barrier. But what is this stuff made of, and how does it work? [link] [comments]  |

| Posted: 25 Mar 2021 09:10 AM PDT The grandson has his Y chromosome because of his father and paternal grandfather. The X chromosome is either from his maternal grandmother or grandfather, because the mother has an X chromosome from both grandparents obviously. How does a biological relationship still exist if this is what's happening? [link] [comments]  |
| Is it really that bad for a battery to recharge it before it’s completely empty? Posted: 25 Mar 2021 05:17 PM PDT Why is it bad for a phone battery for example to plug it into a charger before it's lost its charge? In my head that always made no sense because i would think that it would be more taxing on a battery to get it going from zero again. Obviously it's not like this, but why? By the way i am not too sure if the ‚Engineering' flair is the right one to chose, perhaps chemistry would've been more appropriate? [link] [comments]  |
| How is CPT symmetry maintained if each individual aspect of it is violated? Posted: 25 Mar 2021 09:55 AM PDT Still learning about the subject, but I'm really confused on why CPT symmetry works at all. [link] [comments]  |
| Do you become contagious after getting a vaccine? Posted: 26 Mar 2021 02:31 AM PDT This might be a stupid question but I was asked whether you become contagious after getting a vaccine (Covid vaccine in this case, specifically Sputnik), and my first intuition was no, but don't you get a weakened virus by the vaccine and can't that one spread? AFAIK, the vaccine contains an adenovirus and not THE corona virus so you can't spread the actual disease but I'd like if someone else would confirm and explain it better. [link] [comments]  |
| Where in the process for formal FDA approval are any of the three COVID vaccines beyond the EUA? Posted: 25 Mar 2021 07:42 AM PDT I have tried scouring the FDA website and I can't find anything beyond a dozen explanations on what a EUA is and why the vaccine was accepted. I'm wondering where in The process to formal approval any of the three vaccines are and where I can go to educate myself further? [link] [comments]  |
| Posted: 25 Mar 2021 07:23 AM PDT Seems odd that when trying to find information on attemps to develope treatments for rabbies the information is so scant. Is it impossible to develope antibody serums or amtivirals for rabbies? Or does the effectiveness of the vaccine mean there is little interest? [link] [comments]  |
| Why does the pH of hydrogen fall at such a perfect integer value? Posted: 25 Mar 2021 09:43 AM PDT I find it weird that at 25C, Kw = 10^-14 such perfectly. Why are these perfect powers of 10/why is their log in base 10 an integer? Is it just a happy coincidence? Is it why we picked 25C to be the temp at which most acid-base chem takes place?
