| Are there any autoimmune diseases that have been "cured?" Posted: 29 Oct 2020 03:16 PM PDT All the autoimmune disorders I am familiar with have the same general treatment idea - manage the symptoms. Some types may go into remission here and there but this is unpredictable. Is this correct? Are there any that can be considered "cured" after medical treatment? [link] [comments]  |
| Posted: 30 Oct 2020 04:00 AM PDT I am a research scientist at NASA Goddard Space Flight Center and SETI Institute. My research focus is on detection, vetting and characterization of transiting exoplanets from Kepler, K2, and TESS, with the goal of understanding how these exoplanets form, evolve, and compare to the Solar System. Now citizen scientists can be part of the hunt for exoplanets, too, by joining Planet Patrol. The goal of Planet Patrol is twofold:
Automated methods of processing TESS data sometimes fail to catch imposters that look like exoplanets. The human eye is extremely good at spotting such imposters, and we need citizen scientists to help us distinguish between the look-alikes and genuine planets. Some of the most exciting planet candidates are difficult to analyze. For example, Earth is a small planet with a long orbit, which means it would generate a weak signal in the data and be difficult to detect, vet and ultimately confirm. Planet Patrol volunteers will help me and my team sift through TESS images of potential exoplanets by answering a set of questions for each - like whether an image contains multiple bright sources or resembles stray light, rather than light from a star, or is simply too noisy for detailed analysis. These questions help us narrow down the list of possible planets for further follow-up study. Links:

| How can pointing tuned lasers at atoms/molecules cool them down? Posted: 29 Oct 2020 09:40 PM PDT Recently I was watching a video, and it mentioned that there is a process used to supercool things by shining lasers at it. Is this because of a "vibration-damping" effect that outweighs the energy put in by the laser? [link] [comments]  |
| Why aren’t alcoholics all overweight? Posted: 29 Oct 2020 10:05 PM PDT Asking because I am wondering if alcohol metabolizes faster and thus .... doesn't stick on to turn to fat? If alcohol is generally high in calories (90 for a shot of vodka!!) why aren't people who are addicted to alcohol heavier? Is it because of alcohol itself, or am I making a bad generalization.

| Why does colour have a 3D (RGB) representation but sound doesn't, despite both being spectra? Posted: 29 Oct 2020 11:55 PM PDT Sound is a spectrum of frequencies and so is light but colour has a representation with RGB as components, but sound doesn't? Aren't they both one dimensional frequencies? What is different about light? If we can see light with only 3 types of sensors could we do the same for sound? [link] [comments]  |
| What causes Nitroglycerin to detonate? Posted: 29 Oct 2020 06:02 PM PDT From what I've read, decomposition or physical shock are what cause the detonation. What I'm not understanding is the chemical portion of this. Is is a rearrangement of molecules, or breaking a bond? What is it about the shock or decomp that actually initiates the explosion?

| Is it nothingness between galaxies or is there constantly objects? Posted: 29 Oct 2020 02:40 PM PDT I know this sounds stupid. But aren't galaxies spread far apart from one another. And if so is it like nothingness in between excluding asteroids and such, or do they all just kind of merge together? [link] [comments]  |
| Do you produce antibodies faster on reinfection? Posted: 29 Oct 2020 09:50 AM PDT Looking at this post, u/Alwayssunnyinarizona says it takes ~5 days to produce antibodies. If you've already been previously infected and your B cells have the "blueprint" for antibodies, do you produce antibodies faster on reinfection? [link] [comments]  |

| Why do gravitational slingshots work? Posted: 29 Oct 2020 06:16 PM PDT I understand what a gravitational slingshot is, but I don't understand why it works in the first place. I understand that approaching the high gravity body would cause you to speed up, but wouldn't you lose an equal amount of speed while being shot away from the body? [link] [comments]  |
| Posted: 29 Oct 2020 09:31 AM PDT While we're on the subject, as telescopes get more powerful, do they see more recent events? If a star 100 light years away goes supernova, we won't see it happen with our own eyes for 100 years. Will a telescope decrease this time lag? I feel like I'm oversimplifying this, though.

| How does sex determination in amphibians work? Posted: 29 Oct 2020 08:43 AM PDT So Mammals and Birds use a form of Genotypic Sex Determination XY and ZW systems respectively but what do amphibians use? Reptiles and Fish have various modes of sex determination but I'm more curious as to what amphibians use. I read that amphibians even have two homomorphic sex chromosomes so their XY or ZW chromosomes are almost identical in gene content and size. How do they even differentiate and also how do they recombine and not degenerate like the Y and W chromosomes in Mammals and Birds? The XY/ZW chromosomes are heteromorphic in Birds and Mammals. Also, don't get the terminology confused XY/ZW in Birds and Mammals are not the same as the ones on Amphibians it's just a new way of labeling. [link] [comments]  |
| Posted: 29 Oct 2020 07:12 AM PDT I'm struggling to understand how the process of natural selection is capable of developing something capable of perceiving objects and not just using light as photosynthesis. [link] [comments]  |
