| Posted: 18 Nov 2021 04:01 AM PST In recognition of Hunger and Homelessness Awareness Week (#HHWeek), join a discussion about the societal and medical problems that are not only faced by individuals with homelessness and mental illness, but also the limitations faced by the providers and care agents. Ira Glick, MD is an academic psychiatrist, Professor Emeritus of Psychiatry and Behavioral Sciences, previously Director of Inpatient Hospitalization Services, and Chief of the Schizophrenia Clinic at Stanford University School in addition to having been professor at UCSF and Cornell. Jack Tsai, PhD serves as Campus Dean and Professor of Public Health at the University of Texas Health Science Center at Houston. He is a licensed clinical psychologist with additional training in psychopharmacology and conducts research on severe mental illness, homelessness, and trauma. Read two recent articles at The Journal of Clinical Psychiatry co-authored by our hosts:
We'll be on from 11a - 2p ET (16-19 UT), AUA! Username: /u/PsychiatristCNS [link] [comments] |
| Why do viruses, such as smallpox, chickenpox, and monkeypox, cause random lesions and blisters? Posted: 18 Nov 2021 12:00 AM PST Viruses like smallpox lead to blisters, rashes, and or lesions on the surface of the skin. How does the virus cause this an why do the 'pox' tend to appear randomly on the body. What decides the location of these marks and their density or cluster formation? [link] [comments] |
| Posted: 18 Nov 2021 10:52 AM PST By 1950, the major blood groups and RH would surely have been known for transfusion, (eg in North Carolina where the crash occurred) [link] [comments] |
| Is the time component of spacetime expanding as well? Posted: 18 Nov 2021 09:03 AM PST It's been established that space is expanding - accelerating, even. But my layman's understanding is that in spacetime, space and time aren't really separate concepts, they're just different relative directions that something can move through it, to use the loaf of bread analogy. But it's one can stretch the analogy further, that would imply time is also expanding. What does that even mean? [link] [comments] |
| What are the similarities and differences between short and long acting antipsychotic injections? Posted: 18 Nov 2021 10:58 AM PST Hello, I'm trying to understand the similarities and differences between these two forms of injections. For example, what is different about long acting injections that makes the medication last so long? Also, what ingredients, if any, are found in both of these types? Thank you. [link] [comments] |
| Would adding more mass to Earth change its orbit? Posted: 17 Nov 2021 11:56 PM PST If we start mining other planets, or the asteroid belt, and begin bringing raw materials to Earth, what are the implications? Obviously this endeavor would be extremely resource and energy intensive, but let's assume for the sake of the thought experiment that we have some sort of super efficient fuel by the time we start bringing iron ore down in shipping containers. If we increase the mass of Earth, wouldn't we need to figure out a way to increase the speed of the orbit in order to avoid plunging into the sun, or crashing into another planet? With that being said, if we start shooting ships out into the solar system at a high rate, we would be removing mass from the Earth as well, which would also alter the orbit of Earth. I've never seen or heard this topic discussed in real world or SCI-FI scenarios. What say you? [link] [comments] |
| Does T cell thymic selection occur in distinct step or not necessarily? Posted: 18 Nov 2021 07:03 AM PST I've seen some articles/references that say they occur in 2 successive steps that differ in temporal and spacial aspects. On the other hand other articles and références say it isn't necessarily that positive selection occur before negative selection. I feel my head is puzzled, can someone simplify this for me? [link] [comments] |
| Is it possible for a substance to be so sticky that passing gas particles would stick to it? Posted: 18 Nov 2021 01:55 AM PST |
| What would happen with an explosive reaction in which the material could not expand? Posted: 18 Nov 2021 05:10 AM PST So with a chemical reaction such as gun powder or high explosive that reacts but quickly turning into a gas. What would happen if it was in a container that wont break essentially if an explosive reaction was forced into a situation in which the material could not expand. What would happen?

| Can we predict coronal mass ejections? Posted: 18 Nov 2021 02:12 AM PST Can we predict whether a CME will struck the earth? If yes, how do we respond/prepare? [link] [comments] |
| How does the phase of emitted light relate to the oscillation of a charged particle? Posted: 18 Nov 2021 04:51 AM PST Let's say there is a a dipole oscillating up and down (Z axis). This causes it to release light. Will the electric-field portion of this light oscillate on the same plane (z axis) or will it oscillate perpendicular? And will the positive part of the wave match the positive part of the dipole or will it be flipped? [link] [comments] |
| Posted: 18 Nov 2021 06:49 AM PST I'm an AP bio teacher and I can explain in detail how nondisjunction occurs, I've looked around the internet and I can find a thorough explanation of the causal mechanism and how nondisjunction occurs in this syndrome and how the isochrome 12 is produced. I could use the guidance of an expert biologist here who may understand this better than I. [link] [comments] |
| What exactly does "relative to C-12" mean? A question regarding atomic weight. Posted: 18 Nov 2021 10:26 AM PST So I'm trying to understand the definition of atomic weight (? a bit confused with the names as well). Here's what I understand so far: - masses of atoms are cumbersome to express in kilograms, so scientists came up with a more simplified way of expressing them: - by using the stable and abundant C-12 isotope, containing 12 nucleons, they defined the atomic mass unit as 1/12 of the atomic mass. Since the mass of the electrons is negligible, this essentially gives us an approximate mass of one nucleon (a proton or a neutron) - by using C-12 as a baseline we can now define other isotopes' atom masses relative to C-12. The thing I'm trying to understand is why other isotopes masses aren't integers like C-12. I thought the whole idea was to get integer numbers as an easy way of measuring atoms masses. My google searching found the following, which I'm struggling to understand: - due to isotopes' different binding energies they all have different mass defects. The mass defect is defined as the sum of the components' masses minus the experimentally measured mass. I sort of get this, but: - because the masses are relative to C-12 they will not be integers. ^ This is the thing I'm struggling with. Relative how? So the C-12 experimentally measured mass / 12 equals 1 amu, meaning that the C-12 mass defect is "baked into" this unit. How do we determine the masses of other isotopes then, relative to C12? Do we just experimentally measure the weight of the isotope atoms in kilograms, and then express them in amu? Is this what "relative to C-12" means? Any insights are appreciated! [link] [comments] |
| How does adderall exactly work? Posted: 17 Nov 2021 09:40 PM PST Why does it seem to focus people with ADHD but give others a lot of energy? And what's with all the side effects? What does it do to the brain? [link] [comments] |

| Posted: 17 Nov 2021 04:36 PM PST I understand there's likely foreign bodies on certain hairs etc, but I'm curious what the body is doing to create that deep, tense 'sneeze approaching' sense sensation. [link] [comments] |
| IBM Eagle new quantum computer how does it work? Posted: 17 Nov 2021 02:38 PM PST Hi, IBM has recently announced new, the fastest quantum computer called Eagle. Can you comment more how does it work? [link] [comments] |
| Are all muscles contracting? As in there are no "push" type muscles? Posted: 17 Nov 2021 04:11 PM PST What about other species besides humans? And what are non-contracting (I'm assuming stationary) muscles generally used for? [link] [comments] |
| Why are certain cancers more common than others? Posted: 17 Nov 2021 08:28 PM PST Lung Cancer, Breast Cancer, and Prostate Cancer rank among the most common cancers. Why are cancerous growths more common in these locations than in a place like your arm or brain? [link] [comments] |
| Could exposure to radioactive radiation be "good"? Posted: 17 Nov 2021 09:59 AM PST So I'm just curious no I'm not gonna try to expose myself to radiation and I know it's very likely to cause permanent damage or kill you but was I'm wondering is whether there is a chance when it changes your dna that it makes you "better" [link] [comments] |
