| Posted: 02 Dec 2021 04:01 AM PST Multiple sclerosis is a complex disease that affects the central nervous system, including the brain, spinal cord, and optic nerve. Many of its symptoms are easily noticed, like gait, balance, tremor, and speech. But others are not visible to the naked eye - like fatigue, cognitive dysfunction, and pain - and make day-to-day life with the disease difficult to navigate for the more than two million people living with MS globally. Today from 11a - 2p ET (16-19 UT), Patricia Coyle, MD and Patricia Melville, RN join us to take your questions about the invisible symptoms and disease related to MS. MS Team Meeting: The Impact of the Invisible Symptoms of MS is a new four-part video series featuring Coyle and Melville for The Journal of Clinical Psychiatry. Watch as they share an in-depth conversation with Lillian, a woman with MS for the past 30 years who shares a candid account of life with this disease. Patricia K. Coyle, MD is the director of the MS Comprehensive Care Center and professor of neurology at Stony Brook Neurosciences Institute. Patricia Melville, RN, NP-C, CCRC, MSCN is a supporting specialist at Stony Brook Neurosciences Institute. Learn more about multiple sclerosis in the MS Clinical Resource Center.

| Posted: 02 Dec 2021 01:18 AM PST With the recent discovery of Omicron and it's apparent rapid transmission and positive identification across the globe, how do current COVID tests determine which variant is being detected as present? Which tests have this capability? I have only ever seen tests that detect the presence of a coronavirus, but not the exact variant. If the Omicron variant was just discovered days ago in South Africa, how would tests already in use in Europe, USA and Asia be able to not only detect the presence of but also positively determine which variant was detected, especially when that variant was not known to exist until this week?

| Where do common cold and flu infections come from? Posted: 02 Dec 2021 05:16 AM PST My question is about the human virome and wether you get get sick with a cold or flu without any human to human interaction (aka in isolation). I know that, for example, staph bacteria is normally found on the skin of healthy individuals and then occasionally become pathogenic if they get into skin pores, or skin cuts or the person's immunity drops. Does the same thing happen with viruses that cause the common cold or flu? Are rhinoviruses for example normally found in healthy humans like staph bacteria is found on healthy skin? Do these viruses then become pathogenic due to drops in immune function? Or do all cases of common cold and flu infections come from viruses that a healthy human is exposed to from outside their body? Thank you so much [link] [comments] |
| Dear Astronomers / Physicists, could you help me understand tidally locked planets? Posted: 02 Dec 2021 05:32 AM PST I'm curious about tidally locked planets orbiting red dwarves, such as GJ 581g, and their potential for sustaining atmospheres or even life. As one side of the planet is faced away at all times from its star, do the freezing temperatures that occur prohibit an atmosphere from forming? Also, in regards to the red dwarves the planets must be orbiting so closely, is radiation due to closer proximity also a problem? As many have taken the time during the epidemic to explore themselves a little more, I've decided to pick up science fiction writing. As a large part of the story is placed on a tidally locked planet, it's important to me to keep things realistic in a sense. Looking forward what you guys can educate me on. [link] [comments] |
| What SI units are used to measure the highest levels of ionizing radiation? Posted: 02 Dec 2021 12:40 PM PST Hi, everyone! So, I'm a volunteer firefighter with an interest in hazardous materials response. One of the aspects that I've always wondered about is the radiological side of things. I've done extensive research into nuclear disasters such as Chernobyl and Fukushima and have always pondered this question. I'd greatly appreciate it if someone could help me out. [link] [comments] |

| What is the mechanism behind certain covid variants crowding others out? Posted: 02 Dec 2021 01:40 PM PST I often hear people talk about this as if one variant is displacing the efficacy of another to spread but I can't figure out why that would be. My best guess is that this is a misnomer and one does not crowd out another, but instead previous ones taper off and new ones arrive. As those new ones peak it casts the impression that displacing others when in fact the two are on two different infection cycles. [link] [comments] |
| How much the COVID treatment improved ? Posted: 02 Dec 2021 09:59 AM PST I've seen a lot of news about vaccine development this year but almost none about how much we improved at curing it. [link] [comments] |
| How is it possible that we are running out of water? Posted: 01 Dec 2021 07:17 PM PST I imagine this is a common point of confusion. I am aware that only a small percentage of water on earth is freshwater, only a small percentage of that is liquid. My question is - does the actual amount of fresh water on earth decrease? If not, how is it possible that we are running out? Where is it going? [link] [comments] |
| Did Whales always live in pods? Posted: 01 Dec 2021 05:08 PM PST Late in the book Moby Dick Ishmael tells the reader that whales only started living in pods as a defense mechanism after humans started hunting them. Is this true? I'm aware Moby Dick takes some liberties with actual science (such as claiming whales are a fish rather than a mammal) but I can't find any information confirming or debunking this particular claim.

| Posted: 01 Dec 2021 07:38 PM PST The assertion was made at https://www.reddit.com/r/MapPorn/comments/r6jxsh/each_us_state_split_in_half_by_population/hmtqkqq/ that it is always possible to draw a straight line to divide a given contiguous territory into two parts that are both equal in area and equal in population. For this purpose, assume that when I say "two parts", I don't mean "two parts that are also contiguous." So if I've got a crescent-shaped territory and my line ends up dividing the territory into a "middle" part and two non-contiguous bits that are the horns of the crescent, that line isn't invalid for that reason, if you follow me. Is the conjecture true? Is it always possible to use a straight line to divide a contiguous territory into parts that are both equal-area and equal-population? [link] [comments] |
| Do the relative positions of stars in the Milky Way change as the galaxy rotates? Posted: 01 Dec 2021 07:24 PM PST For example, do they all move as if they are glued in place on a record on a record player, or do they move like items going down the drain, with the central stars revolving more rapidly than the peripheral stars? [link] [comments] |
| How did the shift from unicellular to multicellular life occur? Posted: 01 Dec 2021 06:16 PM PST To start off, I'd like to clarify that I'm not doubting the validity of evolution and natural selection. My question is more specific to how cellular life shifted from simple unicellular organisms to a group of cells like sponges, and even organised into tissues in more complex species.
