| Posted: 02 Jun 2020 10:57 AM PDT Black lives matter. The moderation team at AskScience wants to express our outrage and sadness at the systemic racism and disproportionate violence experienced by the black community. This has gone on for too long, and it's time for lasting change. When 1 out of every 1,000 black men and boys in the United States can expect to be killed by the police, police violence is a public health crisis. Black men are about 2.5 times more likely to be killed by police than white men. In 2019, 1,099 people were killed by police in the US; 24% of those were black, even though only 13% of the population is black. When black Americans make up a disproportionate number of COVID-19 deaths, healthcare disparity is another public health crisis. In Michigan, black people make up 14% of the population and 40% of COVID-19 deaths. In Louisiana, black people are 33% of the population but account for 70% of COVID-19 deaths. Black Americans are more likely to work in essential jobs, with 38% of black workers employed in these industries compared with 29% of white workers. They are less likely to have access to health insurance and more likely to lack continuity in medical care. These disparities, these crises, are not coincidental. They are the result of systemic racism, economic inequality, and oppression. Change requires us to look inward, too. For over a decade, AskScience has been a forum where redditors can discuss scientific topics with scientists. Our panel includes hundreds of STEM professionals who volunteer their time, and we are proud to be an interface between scientists and non-scientists. We are fully committed to making science more accessible, and we hope it inspires people to consider careers in STEM. However, we must acknowledge that STEM suffers from a marked lack of diversity. In the US, black workers comprise 11% of the US workforce, but hold just 7% of STEM jobs that require a bachelor's degree or higher. Only 4% of medical doctors are black. Hispanic workers make up 16% of the US workforce, 6% of STEM jobs that require a bachelor's degree or higher, and 4.4% of medical doctors. Women make up 47% of the US workforce but 41% of STEM professionals with professional or doctoral degrees. And while we know around 3.5% of the US workforce identifies as LGBTQ+, their representation in STEM fields is largely unknown. These numbers become even more dismal in certain disciplines. For example, as of 2019, less than 4% of tenured or tenure-track geoscience positions are held by people of color, and fewer than 100 black women in the US have received PhDs in physics. This lack of diversity is unacceptable and actively harmful, both to people who are not afforded opportunities they deserve and to the STEM community as a whole. We cannot truly say we have cultivated the best and brightest in our respective fields when we are missing the voices of talented, brilliant people who are held back by widespread racism, sexism, and homophobia. It is up to us to confront these systemic injustices directly. We must all stand together against police violence, racism, and economic, social, and environmental inequality. STEM professional need to make sure underrepresented voices are heard, to listen, and to offer support. We must be the change. Sources:

| Why are diabetics considered to be at higher risk of death from COVID_19? Posted: 17 Jul 2020 04:25 PM PDT My little brother is diabetic, and I was wondering why I read everywhere that people with preexisting conditions like diabetes are susceptible to more severe symptoms of the virus. I understand that a person with a condition that would affect their immune system would have a harder time fighting the virus, but I don't see how a diabetic would struggle with it.

| Posted: 18 Jul 2020 05:06 AM PDT Since we've confirmed that early humans interbred with Neanderthals and Denisovans and that some people have genes that can be traced back to them, can we also assume that there are likely other modern genes that were acquired from other hominids we just don't have a fossil record of?

| Posted: 17 Jul 2020 07:36 PM PDT As the question implies, if you have two sets of twins (male and female) and each pair has a child, of the same sex or different sex, would you be able to tell what child "belongs" to what parents? If each dad and mom shares identical DNA with their twin, wouldn't these children (who are cousins) be genetically identified as siblings? And in addition, can you tell if there's any genetic difference between identical twins? [link] [comments]  |
| What kind of effect will anti-vaxers have once there is a vaccine for COVID-19? Posted: 17 Jul 2020 05:54 PM PDT In other words, if they don't vaccinate, could it be possible that it destroys the chance of a successful vaccine deployment for the rest? [link] [comments]  |
| What seems to be the mortality rate of COVID? Posted: 18 Jul 2020 02:03 AM PDT Some say it's up to 4%, but I also hear 1%. What does it seem to be at this point now we know more? [link] [comments]  |
| Has the ratio of Carbon 14 to Carbon 12 in the atmosphere been the same over Earth's history? Posted: 18 Jul 2020 07:16 AM PDT Hi all! I'm curious about the question "has the ratio of C14 to C12 in the atmosphere (1 to 1 trillion) remained a constant across Earth's history?" This came up because I'm active in discussions on Young Earth Creationism. During one of these discussions, I came across this article: https://answersingenesis.org/geology/carbon-14/doesnt-carbon-14-dating-disprove-the-bible/ The main argument in the article is this: Carbon 14 dating is unreliable because assumptions are made about the ratio of C14 to C12 in the Earth's past. Since the ratio could have been different in the past, we can't get accurate readings on the age of dead animals/plants.
I also came across a short article that directly conflicts with the above: https://chem.tufts.edu/science/FrankSteiger/carbon14.htm
So is the ratio of C14 to C12 over history an assumption? Or do we know that the 1 to 1 trillion ratio has been more or less a constant over the history of life on Earth? If it's not a constant, how to we resolve that and account for the difference when dating fossils? [link] [comments]  |
| Oxford COVID-19 vaccine, why use a different virus ? Posted: 17 Jul 2020 10:24 PM PDT Excerpt from the article. "The technical name of the vaccine is ChAdOx1 nCoV-19, as it is made from a virus called ChAdOx1, which is a weakened and non-replicating version of a common cold virus (adenovirus). The vaccine has been engineered to express the SARS-CoV-2 spike protein." Question: 1- Why do they have to use a different virus, why not use inert COVID-19 virus itself? 2- Why do they have to engineer a spike protein when COVID-19 already has the spike? https://www.ovg.ox.ac.uk/news/trial-of-oxford-covid-19-vaccine-starts-in-brazil [link] [comments]  |

| Why does motion sickness cause vomiting? Posted: 16 Jul 2020 10:01 PM PDT I have heard of a theory that says that conflict in balance systems causes motion sickness, and that this conflict looks like poisoning to the brain, which causes vomiting to expel the poison. but I would like something different, a different explanation. would motion sickness cause nausea and vomiting by the vagus nerve?
