| Posted: 06 Jul 2020 04:00 AM PDT We are Criminologists from Birmingham City University and editors on the new book Video Games, Crime and Next-Gen Deviance: Reorienting the Debate. After a drunken debate about the myopic view of video games causing violence after the tragic incident at Sandy Hook we decided to write a book. We argue that such discussion are reductive, inconclusive and frankly boring. We and our fantastic contributors then highlight some key areas in which we can recognise deviancy embedded within video games! The book is open access so free to download electronically and available here: https://www.amazon.com/Video-Games-Crime-Next-Gen-Deviance-ebook/dp/B087BV7H9V We will be on from 1pm ET (5pm GMT), ask us anything!

| How do Sperm Whales find Giant squid? Posted: 05 Jul 2020 10:27 AM PDT They dive to extreme depths to find the squid but how do they actually locate them? Do they use sonar or smell or some other sense to hone in on them? I imagine its pitch black down there and the ocean is huge so it blows my mind they are able to survive off such a strange and hard to get to diet. [link] [comments]  |
| Why don't people with heart valves, titanium hips, breast implants etc need anti-rejection meds? Posted: 06 Jul 2020 06:31 AM PDT I already feel like this is going to end up being a stupid question, but if your immune system rejects foreign objects in your body, why doesn't it reject those kinds of things like it does organ transplants and, at times, things like piercings or catheters? Thanks so much! [link] [comments]  |
| What is the significance of community transmission of a disease during a pandemic? Posted: 05 Jul 2020 11:48 PM PDT Why is it such a big thing? What are the implications of community transmission stage in an area during a pandemic? Can lack of human resource required to properly track the source of infection of each infected person lead to this stage? [link] [comments]  |
| How are multiple signals passed over wires (phone lines, fiber optics, etc...) without interference? Posted: 05 Jul 2020 03:48 PM PDT I was thinking about the old days especially when most communication was over the phone lines which I know to be multiple individual strands of wire spanning thousands of miles with various interconnections. But, if my neighbor and I are making a phone call at the same time, how do the lines keep those 2 signals entirely separate when its on the same line for at least a part of the transmission?

| Viruses come from animals but where did that animals disease that adapted to us come from? Posted: 05 Jul 2020 10:51 PM PDT I read some previous threads that all say that viruses come from animals and "hop on over" to humans but where does the first version of that virus come from? If I'm not mistaken, human viruses are usually mutations of animal viruses. Well where did the animal viruses come from? Other animals? Where did those animal viruses come from? Could we get viruses from eating animals with "broken" cells like cancer cells which then use their cell mutations to become a new virus? I'm not a biologist, I hope I didn't say something weird.

| Does everyone have cancerous cells? Posted: 06 Jul 2020 12:12 AM PDT I think I read it or heard it once that people have it dormant in their system and something "triggers" it to become active. [link] [comments]  |
| Posted: 05 Jul 2020 11:33 PM PDT Light is an electromagnetic wave where the magnetic field creates an electric field and so on, to create a wave of light that is self propagating without the need for any medium. When talking about young's double slit experiment, it is proved light has wave properties due to the interference pattern since light photons are actually waves of probabilities (places the photon has a probability at landing). So the confusing part is reconciling these two ideas of waves. I can visualize a wave that is created from all the potential locations of a photon (and an interference pattern from this). But then instead of a wave of potentials, we can start talking about the EM wave. I guess I am just confused. Are these two concepts the same wave? And what is the proper explanation?

| Posted: 05 Jul 2020 08:56 PM PDT Okay so I'm French Lebanese and currently live in Lebanon while part of my family live in France. Initially France was hard hit, and quarantined for roughly 2 months and half. They re opened and the population acts like there's no virus since mid may, yet there's no crazy increase in cases or deaths. Same situation in Lebanon, we quarantined very very early, for 3 months. Apart from the airport that just reopened, we've been de quarantined since the beginning of June and everyone is acting like there's no virus (nightclubs, pubs...) yet we have little cases every day and no increase in deaths. I don't understand how come it's not rising exponentially again. Or is it a respite until fall? [link] [comments]  |

| Posted: 05 Jul 2020 10:23 PM PDT For purposes of the question, assume the following about the vaccine: Phase 2 trials have shown safety and efficacy across all age groups among the trial participants The vaccine is RNA based There's been some discussion about challenge trials for a COVID-19 vaccine, but practically no discussion of widespread early access in western nations, though the Chinese military has already started inoculating its troops with a Chinese RNA-based candidate. I understand that administering a treatment to a healthy population is riskier than administering a treatment to a sick population. However, I'm sure I don't need to mention in this community that COVID-19 death tolls are almost certainly higher than reported, that people will die due to untreated chronic conditions, and that the economic effects of the pandemic will reverberate for generations. And that's all on top of a baseline of a disease that is exceptionally virulent and deadly, that America clearly lacks the sustained willpower to rein in through distancing measures, and that has yet to take its toll on many parts of the world. Taking even some carriers out of the population would save lives. With RNA-based vaccines being safer than historical methods of inoculation and phase 1/2 trials showing promising results,it seems that there are greater questions about efficacy than there are about safety. If the concerns are about efficacy, then the risk of making an unproven vaccine widely available might be giving ammunition to anti-vaxxers. But this risk can be mitigated by being transparent with the public that the vaccine has not been shown to be efficacious, and making people sign waivers consenting and understanding to what they are taking. Is there something that I'm missing in the risk profile of an RNA-based vaccine, or is the unwillingness of the FDA/biotech/medical community to take risks even in the face of mass death a reflection of an obsession with precision based on a history of bad risk taking (and flat out abuse) within the community and fear of further reputational harm? Obviously there is some hypothetical combination of virulence and deadliness that would justify this ethically -- what do you think it would be in the eyes of the scientific community?

| Can you help me understand what a stretcher is? Posted: 05 Jul 2020 08:45 AM PDT Stretchers as part of the Antibody-Drug Conjugates formulas. Hello! I'm a translator and I'm trying to understand what a "stretcher" is in order to be able to find a suitable translation. All the texts I've found talk about the "stretcher" as something well known, but I don't know them! If this post is breaking any rule, I'm really sorry. [link] [comments]  |
| On average how old are icebergs estimated to be? Posted: 05 Jul 2020 06:48 AM PDT Tried to search through r/askscience, but didn't see anything similar. To clarify how old and any information about how this is determined would be very interesting [link] [comments]  |
| Posted: 05 Jul 2020 06:24 AM PDT Like any primitive vacuum pump. Not necessarily the complex modern ones. I don't get how all air molecules can be removed from a container. [link] [comments]  |
| Will we get sufficient oxygen, if we wear the face mask through out the day during pandemic? Posted: 05 Jul 2020 10:12 PM PDT Actually, which face mask we should prefer? Clinical or cloth mask? By wearing, whether we will get sufficient oxygen for inhalation? [link] [comments]  |
