We’re signing off for now. Thanks for all your great questions! Tune into the LIVE expansion at 5:30am ET on Thursday on NASA TV (www.nasa.gov/ntv) and follow updates on the @Space_Station Twitter. We’re a group from NASA and Bigelow Aerospace that are getting ready to make history on Thursday! The first human-rated expandable structure, the Bigelow Expandable Activity Module (BEAM) will be expanded on the International Space Station on May 26. It will be expanded to nearly five times its compressed size of 8 feet in diameter by 7 feet in length to roughly 10 feet in diameter and 13 feet in length. Astronaut Jeff Williams is going to be doing the expanding for us while we support him and watch from Mission Control in Houston. We’re really excited about this new technology that may help inform the design of deep space habitats for future missions, even those to deep space. Expandable habitats are designed to take up less room on a rocket, but provide greater volume for living and working in space once expanded. Looking forward to your questions! *Rajib Dasgupta, NASA BEAM Project Manager *Steve Munday, NASA BEAM Deputy Manager *Brandon Bechtol, Bigelow Aerospace Engineer *Lisa Kauke, Bigelow Aerospace Engineer *Earl Han, Bigelow Aerospace Engineer Proof: http://www.nasa.gov/press-release/nasa-televises-hosts-events-for-deployment-of-first-expandable-habitat-on-0 We will be back at 6 pm ET to answer your questions, ask us anything!
Abortion is an accepted legal practice, in many countries, (Center for Reproductive Rights 2016), but that does not mean that there are not ethical implications which are being ignored. This article examines the ethical consequences in the light of a new understanding of them: the “infinite crime”. This variety of crime is one in which any given action has infinite consequences of a negative nature. Several motivations for elective abortion are considered individually with regards to their ethics, in the light of this new definition of an ethical crime. These include the desire for the freedom to be lazy; the freedom to be materialist; the freedom of time and its subcategory the freedom to create; and the freedom of movement. Furthermore, rape is examined and the question considered as to whether it is an infinite crime, and whether it is always a crime, at all, in a broader ethical context. The Principle of the Immorality of Conception by Rape, is defined. The issue of how to approach abortion in rape cases, is addressed. Other reasons for abortion are weighed, including abortion for reason of timing; abortion for reason of family sizing, abortion for reason of genetic deformity and abortion for reason of incest. A new value for human life is proposed. The implications for medicine and law, of this new understanding of the ethics of abortion, are outlined.
Hi, we’re Bernadette Woods Placky and Brian Kahn from Climate Central and Carl Parker, a hurricane specialist from the Weather Channel. The last 11 12 months in a row have been some of the most abnormally warm months the planet has ever experienced and are toeing close to the 1.5°C warming threshold laid out by the United Nations laid out as an important climate milestone. We’ve been keeping an eye on the record-setting temperatures as well as some of the impacts from record-low sea ice to a sudden April meltdown in Greenland to coral bleaching in the Great Barrier Reef. We’re here to answer your questions about the global warming hot streak the planet is currently on, where we’re headed in the future and our new Twitter hashtag for why these temperatures are #2hot2ignore. We will be back at 3 pm ET to answer your questions, Ask us anything! UPDATE: The National Oceanic and Atmospheric Administration released their April global temperature data this afternoon. It was the hottest April on record. Despite only being four months into 2016, there’s a 99 percent chance this will be the hottest year on record. Some food for thought. UPDATE #2: We’ve got to head out for now. Thank you all for the amazing questions. This is a wildly important topic and we’d love to come back and chat about it again sometime. We’ll also be continuing the conversation on Twitter using the hashtag #2hot2ignore so if we didn’t answer your question (or you have other ones), feel free to drop us a line over there. Until next time, Carl, Bernadette and Brian
Greetings Reddit! I am Anthony (Tony) Noce, the current Chair of the ACS Committee on Environmental Improvement (http://www.acs.org/content/acs/en/about/governance/committees/cei.html). I have more than 27 years of experience in environmental chemistry and environment health and safety (EH&S) consulting, with a focus on global EH&S compliance as well as due diligence and integration services. I am currently a Principal Consultant with Haley & Aldrich, Inc. (http://www.haleyaldrich.com/) where I work with clients to help control and mitigate their operational risk, particularly in the EH&S arena, while building their business. I have firsthand experience on how scientists and related professionals can lend their perspectives to policy.

We help the American Chemical Society’s members articulate policy statements on environmentally facing issues such as chemical risk assessment, climate change, and various energy and water sources. You can read my ACS Comment published yesterday in Chemical & Engineering News entitled “TSCA reform and changing our practice of chemistry” here: http://cen.acs.org/articles/94/i20/TSCA-reform-changing-practice-chemistry.html?h=-1691421665 I really enjoyed doing this, and hope that you enjoyed it as well. Thank you for all the questions. I got through as many as I could in the time allowed. I plan to come back later today or tomorrow if I can. Who knows, maybe they’ll even invite me back. All the best!
Hi Reddit! I’m Katie Rizzone and I’m a primary care sports medicine physician at the University of Rochester Medical Center. I specialize in musculoskeletal ailments including strains, sprains, tendonitis, fractures, sports concussions, and arthritis, as well as medical problems unique to the female athlete, and runners. As a lifelong athlete, with two young sons who are just getting into sports, I am very passionate about sports safety. One area I’m particularly concerned about is school-age athletes overtraining and specializing in one sport all year long, rather than resting in the off-season. My research looks at what this may be doing to their bodies not just during their competitive years, but in the long term. I’m also working to expand our understanding of who is most at risk from specialization and overtraining – Girls? Boys? Athletes in a particular sport? And I’m looking at the ages of athletes when these injuries start to occur. With that information, we can establish better sports safety guidelines for young athletes. The goal is to help young athletes continue to enjoy sports, and be able to maintain their physical health well into the future. Good morning! I’m here to answer your questions, ask me anything!**
Abstract Pediatric feeding disorders are common, especially among developmentally delayed children. The consequences of having these disorders can be severe: children could suffer from growth failure, chronic illness, and even death. In addition, these disorders have been reported to affect members of the entire family. While some interventions have been implemented to help families with children with these disorders, these studies are limited by small sample sizes and the lack of long-term follow-up visits. Moreover, there is a lack of a standardized system to classify children with these disorders, which directly impacts the diagnoses of children with these disorders. This paper reviews the relevant literature on the impact on the family of these feeding disorders and the current classification systems and interventions used to help children with these feeding disorders. It also recommends further research to create a more standardized classification system and to test the efficacy of current interventions, with the aim of improving accuracy of diagnoses and developing treatments tailored to children’s special needs.
Yang-Mills theories are a very fruitful concept in quantum field theory. Fundamental interactions and its unifications can be described with Yang-Mills theory. However, gravity is still not modeled in the framework of Yang-Mills theory. It is modeled in terms of the Einstein-Hilbert action in the case of semiclassical field theory, but ordinary quantization of the spacetime field fails due to UV divergences. A possible approach to quantum gravity called E-gravity theory avoids UV-divergences. Primary, this theory is based on a spacetime discretization and the assignment of a curvature measure to discretized spacetime. This paper shows that this approach is also a special case of Yang-Mills theory.
Hello Reddit! I’m Chris Jones, BBSRC Future Leader Fellow at Rothamsted Research in the UK. At 14 I wanted to be a soccer player. At 32 I am not a soccer player but instead spend my time attaching insects to pieces of wire. How did this come to pass? Biologist? Molecular entomologist? Molecular ecologist? It’s hard to know what box I tick. But what I do know is that I am interested in researching the genetic basis of the fascinating migrations of insects, and more specifically, insects of agricultural importance. Every year billions of insects take to the skies migrating vast distances to find suitable habitats in which to breed. Forgoing food and reproduction, these journeys are arduous and risky, but the rewards are high. These migrations are often multi-generational - in other words - the offspring inherently know when and where to go. But what is the genetic programme that drives this behaviour? What are the genes involved? And how can we study this in the lab? The goal of my research is to understand the ‘migratory gene package’ in greater detail. So go ahead. Ask me anything. I will be back at 4pm BST. In the meantime you are welcome to find out more about me and my work in a blog entry I recently wrote for Rothamsted Research’s ‘A day in the life of a Research Scientist’http://www.rothamsted.ac.uk/day-life-dr-chris-jones blog series. I’ll be back at 11 am ET to answer your questions, ask me anything! POST-AMA Hi all, it’s 6pm and time to catch what’s left of the UK spring evening. Thanks for all your questions on insect migration. Some really good questions. Thoroughly enjoyed it! Sorry I haven’t answered everything. I will come back and answer a few more tomorrow. If you are interested more in the work I/we do here in the Insect Migration Group at Rothamsted then please find our contact info in the usual places. Enjoy the rest of your Monday folks. All the best.
Hi Reddit! In 2010, we watched Sonia’s mom die of a rapid, mysterious neurodegenerative disease that baffled her doctors. After her death, we learned that it had been a genetic prion disease, and Sonia was at 50/50 risk. We got genetic testing and learned, in late 2011, that Sonia had inherited the lethal mutation, meaning that unless a treatment or cure is developed, she’s very likely to suffer the same fate, probably by about age 50. After learning this information, we abandoned our old careers in law and city planning, and threw ourselves headfirst into re-training as scientists. Four years later, we’re both Harvard biology PhD students, and we work side-by-side Stuart Schreiber’s lab at the Broad Institute, where we are researching therapeutics for prion disease.

Max, The New Yorker, September 27, 2013 We’ll be back at 1 pm EST (10 am PST, 6 pm UTC) to answer your questions, ask us anything! Update: Hi Reddit, we’re going to officially sign off but just wanted to say thank you so much. Four and half years ago, we never would have imagined people taking such an interest in our cause, or our career changes, or this uphill battle we are fighting. It’s humbling to have so many people out there pulling for us. Hopefully this story has many chapters to come. Thank you!
Digital research and scholarship is an area of growth and investment for many libraries, and defined loosely at different institutions. In this job talk, I propose that digital research support be separated from “services” and that libraries must reimagine our role in the research landscape as we embark into this area. I close by suggesting that the adopting of a portfolio management model, proposed by Jen Vinopal at NYU, will serve to coordinize the future of digital research and digital services. The text is lightly edited to make sense outside a presentation format.
Hi reddit! I am Francis Collins, Director of the National Institutes of Health where I oversee the work of the largest supporter of biomedical research in the world, spanning the spectrum from basic to clinical research. In my role as the NIH Director, I oversee the NIH’s efforts in building groundbreaking initiatives such as the BRAIN Initiative, the Big Data to Knowledge (BD2K) Initiative, the Precision Medicine Initiative Cohort Program, and the Vice President’s Cancer Moonshot program. In addition to these programs, my colleagues and I work to promote diversity in the biomedical workforce, improve scientific policy with the aim to improve the accuracy of outcomes, continue NIH’s commitment to basic science, and increase open access to data. Happy DNA Day! We’ve come a long way since the completion of the Human Genome Project. Researchers are now collaborating on a wide range of projects that use measures of environmental exposure, social and behavioral factors, and genomic tools and technologies to expand our understanding of human biology and combat human disease. In particular, these advances in technology and our understanding of our DNA has allowed us to envision a future where prevention and treatment will be tailored to our personal circumstances. The President’s Precision Medicine Initiative, being launched this year, will enroll one million or more Americans by 2019, and will enable us to test these exciting ideas in the largest longitudinal cohort study ever imagined in the U.S. Proof! I’ll be here April 25, 2016 from 11:30 am - 12:15 pm ET. Looking forward to answering your questions! Ask Me Anything! Edit: Thanks for a great AMA! I’ve enjoyed all of your questions and tried to answer as many as I could! Signing off now.
