| What is the difference between a mirror and a white object? Posted: 07 May 2021 12:06 AM PDT So I'm taking physics and we've just finished light. One thing that struck me was that white objects and mirrors both reflect the whole color spectrum so how come a mirror and a white object look so different. [link] [comments]  |
| Posted: 06 May 2021 04:44 AM PDT Wikipedia lists 32 annular lakes, of which 24 are north of the 49th parallel. Follow up question: why are 20 of them in just the three countries of Canada, Finland, and Sweden? What makes these countries more prone to annular lakes than others? Do they account for the majority of land north of the 49th? [link] [comments]  |
| How do non-plugin hybrid cars actually use less fuel? Posted: 06 May 2021 06:34 PM PDT I know that the basics of a hybrid involves using the electric motor at low speeds, and the ICE at higher speeds. And when the car is using the ICE, it charges the electric motors battery, so that it can be used again. But how does this save fuel? A basic understanding of the first law of thermodynamics is that energy cannot be created nor destroyed, only transferred. Wouldn't this mean that the ICE would use more fuel while it is charging the electric engine, negating whatever gain it would have gotten? I feel like it would actually be counterintuitive, because the transfer isn't likely to operate at perfect efficiency. Anyone have more insight into this? [link] [comments]  |

| Posted: 07 May 2021 04:00 AM PDT I am Michael Abramoff, a physician scientist, and also the founder of Digital Diagnostics (formerly IDx, https://dxs.ai), that created the first ever FDA approved autonomous AI. It makes a medical decision without human oversight, and was based on decades of work in neuroscience and neural networks, design of diagnostic AI algorithms, and design of validation trials, in close collaboration with US FDA. This happened in 2018, and I did an AMA here at the time here: https://www.reddit.com/r/askscience/comments/9d5id2/askscience_ama_series_im_michael_abramoff_a/ Since then, the success of Digital Diagnostics allows me to focus on the deep scientific questions around autonomous AI. What are the ethical issues and dilemmas around autonomous AI in healthcare, and how can we solve these to build an ethical foundation for autonomous AI. This framework then helps guide design, development, validation, regulation, liability issues, implementation and even reimbursement. Read more here: https://doi.org/10.1016/j.ajo.2020.02.022, and also in an the issue of the American Journal of Bioethics dedicated to our framework https://doi:10.1080/15265161.2020.1819469 Given its almost infinitely scalability, autonomous AI has the potential to do good on a massive scale. Think of improving access, solving health disparities, address health equity issues, lowering cost of care, and improving care quality, to benefit patients is tremendous. At the same time, because the large scale in which it is deployed, it also has the potential to do harm. That is why it needs to be done the right way. And, thanks to ethical frameworks, we have come far already: inclusion in clinical standards of care, a framework for autonomous AI medical liability, a methodology for autonomous AI's reimbursement incorporating massive cost savings, and most recently a Medicare reimbursement of $55 and more. The healthcare system was built around physicians, nurses, and other human healthcare workers doing "stuff". Research studies, peer reviewed publications, FDA approval, ultimately are not enough for changing in clinical practices. So all these steps, and many more, were necessary to get the results of the science of AI to benefit patients. Now that the technology is real, other companies also have entered the autonomous AI field, we are getting ready to start a trial for a second autonomous AI, for skin cancers, it is time to do another AMA. I am neuroscientist who started studying neural networks to mimic brain function over 30 years ago. I am also a practicing retina specialist - a physician who specializes in ophthalmology with a fellowship in vitreoretinal surgery -; and a computer scientist, with a MS in Computer Science about artificial neural networks, and a PhD in 2001 on "AI" of medical images. I am founder and executive chairman of Digital Diagnostics, and hence have conflicts of interest. You may also know me as one of the original developers of ImageJ, a widely used open-source image analysis app. I have published over 300 peer reviewed journal papers (h-index 66) on AI and retina, and am inventor on 17 patents and 5 patent applications in this area. Because my statements are often under FDA, FTC, or CMS oversight and scrutiny, my answers may then seem unnaturally constrained - I will try to explain when that is the case. I'll be in and out for a good part of the day, AMA! Username: /u/MichaelAbramoff [link] [comments]  |

| What is the difference between the Moon's revolution and the time it takes between New Moons? Posted: 07 May 2021 03:54 AM PDT The moon takes 27.3 days to make a full revolution, yet 29.5 to change from New moon to New moon? What creates the difference? The elliptical orbit? The angle of it's orbit? Please explain to me like I'm a child because I'm going to be explaining it to children! [link] [comments]  |
| What is the difference between the J&J and AZ vaccines? Posted: 06 May 2021 09:04 PM PDT As far as I know, both of them are adenovirus vector vaccines. Is the difference between the two only the way they attained approval (i.e. one using 1 dose in clinical trials and the other using 2) or is there some deeper difference between them that causes any difference in practice? Put another way, if someone receives only one dose of AZ, would they get similar protection as someone who receives the J&J vaccine? People report getting a lot of side effects with the J&J vaccine, but comparatively fewer with AZ's first dose. Is this because of vaccine composition, or is it all unsubstantiated?

| Does light lose intensity when reflected? Posted: 06 May 2021 11:53 AM PDT If so, how does it work? If not, could it be used to make more efficient solar panels or stuff like that? Sorry if the question is too stupid. [link] [comments]  |
| Do insects have a sense of danger? Posted: 06 May 2021 03:17 PM PDT Like if a fly is almost swatted, will they avoid that location later? [link] [comments]  |
| How long do bacteria remain resistant to a drug? Posted: 06 May 2021 08:01 AM PDT We all know about bacteria forming resistance to treatments. Creating so called 'super bugs". But I also read somewhere that when a resistance is formed, doctors stop using the antibiotic, and without the exposure, the bacteria 'forget' how to defend against it after a while and it works again. Is ANY of that true? And how long does bacteria resistance last? [link] [comments]  |
| Posted: 06 May 2021 12:16 PM PDT Is it true that people with O blood group and specifically the O-ve blood group have less chance of getting the COVID-19? And if so, what is the reason behind it? [link] [comments]  |
| Posted: 05 May 2021 11:15 PM PDT Pretty much the title. Is it possible for marine mammals to drown? Are there any recorded instances of drownings in the wild or in captivity? [link] [comments]  |
| Posted: 06 May 2021 08:39 AM PDT So, vaccines like the pertussis vaccine contain a subunit of the pathogen, which the body produces an immune response to. mRNA vaccines, like the ones currently developed to provide immunity against COVID-19, contain the mRNA that produces a modified spike protein found on the virus. Once this protein is constructed, the mRNA is destroyed. My question: After the modified spike protein is produced and the mRNA is destroyed, is it incorrect to say that the mRNA vaccine acts just like a subunit/conjugate/recombinant type vaccine? They both involve the body responding to subunits of the target pathogen, but both simply have different methods of delivering the subunit, right? The source that informed me and triggered me to ask this question: https://www.hhs.gov/immunization/basics/types/index.html [link] [comments]  |
