| Posted: 13 Jun 2022 04:00 AM PDT I am Dr. Helen Okoye, MBBS, FMCPath, FWACP. I am a haematologist currently working as an Attending Physician and Thrombosis Specialist at the University of Nigeria Teaching Hospital in Enugu, Nigeria. My clinical work focuses on thrombosis and haemostasis with a special interest in women's health. I see all kinds of patients with thrombotic disorders including obstetric and cancer patients. I am passionate about women's health and helping my patients to overcome barriers to health care here in Nigeria, many of which are due to cost and/or lack of resources. I am here to answer your questions about what it is like to work as a female clinician in Nigeria. I will be here at 12 p.m. noon US ET (16 UT), AMA!

| Are reptiles capable of affection and forming bonds? Posted: 13 Jun 2022 05:02 PM PDT I thought that was exclusive to mammals and maybe birds, that the Ancient Reptilian Brains literally had not developed the "layers" responsible for what we'd call "emotions" (allegedly, the Limbic System?). Yet, I'm finding out many anecdotal examples of reptiles being loyal or physically affectionate. I'm very confused by this. EDIT: a poster has brought up that we may be confusing "affection," which only mammals can do, with "imprinting," which "simpler" brains can manage. What are the differences between the two, in practice? Can one design tests to distinguish one process from the other, on a behavioral, empirical, tangible, objective level? [link] [comments] |
| Why do I need infinite energy to keep a spring compressed, but a vice doesn't? Posted: 13 Jun 2022 02:02 PM PDT If I take a big strong spring and compress it between my arms, it takes a continuous amount of energy for me to hold it there. However if I put that same spring in a vice and use some of my energy to close the vice, it'll happily sit there closed without me needing to add extra energy to the vice. What's the difference here? Why do I seemingly need an infinite amount of energy to hold the spring closed but the vice doesn't? Where is that energy from me going? [link] [comments] |
| Do different neutron stars differ in composition? Posted: 13 Jun 2022 07:27 PM PDT I know that on the one hand black holes "have no hair" (any two with the same mass, change, and spin are identical), while on the other hand normal stars can be different from each other by having different concentrations of elements (hydrogen-rich vs metal-rich etc.). Which of these extremes is more similar to neutron stars? What material properties, if any, could be different in one neutron star vs another? [link] [comments] |
| Has climate change affected weather forecasting? Posted: 13 Jun 2022 06:51 PM PDT An increase in severe weather events and anomalies is something scientists attribute to climate change. Does this mean weather in some places is more difficult to predict? Does climate change make it harder to create accurate weather forecasts? Or is weather forecast technology able to keep up with changing climates? [link] [comments] |
| Why stem cells can divide endlessly ? Posted: 12 Jun 2022 07:55 AM PDT Specialized cells have telomers which protect their DNA from damaging, but when cell divides, some telomer is lost and daughter cells have it less than parent cell. After some time, DNA is complitly un protected and so, cell dies. Why then stem cells can divide endlessly ? [link] [comments] |
| Do all animals have XX chromosomes for female and XY for male? Posted: 13 Jun 2022 12:37 AM PDT |
| How effective is platelet-rich plasma (PRP) as healing ligaments and tendons? Posted: 13 Jun 2022 09:47 AM PDT There are so many websites claiming it heals all sorts of injuries but they all seem to be doctors selling the product. [link] [comments] |

| Does early humans have any special abilities that was lost through evolution? Posted: 11 Jun 2022 09:09 AM PDT This may be a dumb question. But yeah in a previous post I saw that turtles tracks their home via geomagnetic signature or something. Does humans used to have any senses that we lost through evolution ?? [link] [comments] |
| Does your vision decrease if you use one eye. ore than the other? Read tho whole thing to understand Posted: 12 Jun 2022 05:24 PM PDT I was hit by a van a little while ago and ever since I've had double vision when looking up, down and left. So I've been mainly using my left eye to focus on things. I think I've noticed that my right doesn't seem to be the same quality as my left. Does your vision quality decrease if you don't "exercise" the eye enough? [link] [comments] |
| Posted: 11 Jun 2022 11:20 PM PDT Asking because I have fake nails I glue onto my fingers, which means I'm in skin contact with plastic for weeks and through hot showers. I've heard BPA is a big issue in both these situations so I'm a bit concerned. Is there any way to test this at home? For example, through their reaction with alcohol or through testing their melting point? [link] [comments] |
| How much water is required to produce a single computer chip? Posted: 12 Jun 2022 12:13 PM PDT |
| Does RTV-1 Silicone Rubber react with hand soap in a way that prevents the soap from foaming? Posted: 12 Jun 2022 05:48 AM PDT I was using some silicone rubber (the kind you use to seal gaps between tiles) and some of it got on my hand. When I went to wash it off in the sink with some hand soap I noticed that the soap wasn't foaming, no matter how much soap I put on my hands. After drying off my hands I tried it again and this time the soap was foaming as usual, so my guess is it must have had something to do with the silicone on my hands [link] [comments] |
| Is there a genetic code or mechanism that makes sure that our body grows uniformly? Posted: 12 Jun 2022 12:07 PM PDT Like is there something that prevents our hands from growing significantly larger that the other or our bones from growing through our skin? [link] [comments] |
| Posted: 11 Jun 2022 04:29 AM PDT On a clear night, without light pollution, I can follow the path from Cassiopeia to the Andromeda galaxy, which appears as a dim smear of light. I assume that the closer I travel towards Andromeda (as impossible as that is) the brighter and more visible it will be and therefore it stands to reason that if I am inside Andromeda it will be incredibly bright. I mean, I'd be standing inside something which is giving off enough light to be seen from Earth in a whole other galaxy. I assume our galaxy looks the similar from the perspective of an Andromedan so why does it ever get dark? [link] [comments] |
| Does salt intake (directly or indirectly) affect mental health? Posted: 12 Jun 2022 03:27 PM PDT |
| Is there a difference between a pixel of live footage and animated? Posted: 12 Jun 2022 04:04 PM PDT Does live footage take up more or less data than animated when similar resolutions and stuff is accounted for? Or are there any other differences that I'm just not thinking of at all? [link] [comments] |
| Why does human skin get so thin and fragile as people age? Posted: 11 Jun 2022 09:56 AM PDT |
| Posted: 12 Jun 2022 04:33 AM PDT I know a new species description can be conducted by comparison with other relatives, and they can be described with descriptions and illustrations and studied over time to show their are a unique species, but when some sort of genetics are extracted and analysed, how does this happen ? [link] [comments] |
| Posted: 11 Jun 2022 07:20 AM PDT I have heard that sea turtles travel hundreds of miles and return to their place of birth to lay their eggs. I have heard that fresh water turtles can travel two or more miles by land to their place of birth to lay their eggs. And I have always been told not relocate land turtles, like box turtles, since they will try to get back to where you found them or where they were going. [link] [comments] |
| Is the Hydrogen spectrum fully solved? Posted: 10 Jun 2022 02:24 PM PDT As an undergrad student, I used the Schrödinger equation to solve the Hydrogen atom, but the result would lead to missing transitions. The professor then said that the Dirac equation would give a better result, but it would still lack some corrections from the hyperfine structure and quantum field theory. So, my questions are: 1) Are all the known corrections enough? Or are there transitions that happen using a state that shouldn't exist according to the model? I.e., are all states from the Hydrogen atom in the model? 2) Do these corrections make a closed formula, or are they had to be done using numerical methods? [link] [comments] |
| Are there any other species that use tools to "improve" their environment? Posted: 11 Jun 2022 10:34 AM PDT Adam Savage pointed out that humanity's ability to adapt to our environment (and adapt our environment to ourselves)1 has been a major evolutionary advantage. Clothing seems like the earliest example of this kind of adaptation. Unlike tool use for hunting/gathering, which definitely predated homo sapiens and shows up in other species, is use of tools for creating habitats unique to us? [link] [comments] |
| Have there been any efforts to recover fossils from under sea level? Posted: 11 Jun 2022 08:04 AM PDT |
| Is this paper on a treatment for rectal cancer as promising as it sounds? Posted: 10 Jun 2022 12:36 PM PDT |
