Hi, we’re Drs. Ben Poulter (NASA), Thomas Gumbricht (CIFOR), David Olefeldt (University of Alberta) and Etienne Fluet-Chouinard (University of Wisconsin) — we study techniques to map wetlands around the world, how they change over time, and how this information can be used to understand how wetlands function and provide ecosystem services to people. Wetlands can be mapped using a variety of techniques, from sending people out into the field using inventory techniques to taking advantage of satellites in orbit around the Earth and using the electromagnetic spectrum. Recently, a new map of tropical wetlands was published by Thomas Gumbricht as well as a high-resolution map of global surface inundation by Etienne Fluet-Chouinard, both databases are being used for a variety of purposes, including to understand how wetland affect climate change by emitting methane. Join our AMA to find out how satellites are helping in the quest to learn more about where wetlands are located, how human activities affect wetland area, and how climate change is affecting methane emissions from wetlands. We’ll be back at 12 pm ET to answer your questions, AMA!

I’m Mike Liemohn, a Professor in the Department of Climate and Space Sciences and Engineering (http://clasp.engin.umich.edu/) at the University of Michigan (umich.edu). You’ve probably seen Gravity, The Martian, or The Fantastic Four, so you know that outer space is a dangerous place. But isn’t outer space a vacuum of nothingness? Beyond no air to breathe, what else could possibly hurt you? It turns out…lots! I investigate the physics at work in the almost-nothingness of our solar system. I am also the Editor in Chief of the Journal of Geophysical Research – Space Physics2169-9402/) a leading journal in this field of understanding the Sun, solar eruptions, magnetic storms, the radiation belts, and the aurora at Earth and other planets. I am also currently teaching a very fun course at U-M called SPACE 101: Intro to Rocket Science. I hope to have an engaging discussion with you about the fascinating physics happening in the near-emptiness of outer space, and explore the many ways that space might pose a danger to astronauts, to satellites, or even to power grids here on Earth. I’ll be back at 12 pm ET to answer your questions, Ask Me Anything! The AGU AMA series is conducted by the Sharing Science (sharingscience.org) program. Sharing Science: By scientists, for everyone.

Hello, I am a medical epidemiologist and infectious disease doctor at CDC in the Waterborne Disease Prevention Branch. I work to prevent and stop infections caused by free-living amebas, which are single-celled organisms found in the environment, in water and soil. They cause diseases ranging from a type of encephalitis, or brain infection, to serious eye infections. I support epidemiologic, laboratory, and communication activities related to free-living ameba infections. Acanthamoeba is a free living ameba that can get on your contact lenses, and lead to a painful and disruptive infection called Acanthamoeba keratitis (AK). AK can lead to vision problems, the need for a corneal transplant, or blindness. Luckily, AK and other contact lens-related eye infections are largely preventable. So while I spend a lot of time working on specific free-living ameba infections, I also work with the CDC Healthy Contact Lens Program to help people learn about contact lens-related eye infections and the healthy habits that can reduce your chances of getting an eye infection. For more information about the CDC Healthy Contact Lens Program and our contact lens recommendations, visit our website: https://www.cdc.gov/contactlenses/index.html. I’ll be back at 1 pm to answer your questions, ask me anything!
Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive search for specific terms in tweets on Twitter. The second search examined prescient inquiries submitted to a search engine, highlighted by a comprehensive search for specific search terms submitted to a popular astronomy web site. The third search involved a request for a direct Internet communication, either by email or tweet, pre-dating to the time of the inquiry. Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered. Although these negative results do not disprove time travel, given the great reach of the Internet, this search is perhaps the most comprehensive to date.
Hi! I’m Tony Hey, the chief data scientist at the Science and Technology Facilities Council in the UK and a former vice president at Microsoft. I received a doctorate in particle physics from the University of Oxford before moving into computer science, where I studied parallel computing and Big Data for science. The folks at Physics Today magazine asked me to come chat about Richard Feynman, who would have turned 100 years old today. Feynman earned a share of the 1965 Nobel Prize in Physics for his work in quantum electrodynamics and was famous for his accessible lectures and insatiable curiosity. I first met Feynman in 1970 when I began a postdoctoral research job in theoretical particle physics at Caltech. Years later I edited a book about Feynman’s lectures on computation; check out my TEDx talk on Feynman’s contributions to computing. I’m excited to talk about Feynman’s many accomplishments in particle physics and computing and to share stories about Feynman and the exciting atmosphere at Caltech in the early 1970s. Also feel free to ask me about my career path and computer science work! I’ll be online today at 1pm EDT to answer your questions. Edit: Thanks for all the great questions! I enjoyed answering them.
What we do: Dark matter is a mysterious form of matter that makes up 80% of the matter in the universe. We call it dark matter because it doesn’t emit or reflect any light or radiation, so it’s basically invisible. The ADMX experiment looks for a theoretical type of dark matter known as the axion. These hypothetical particles were developed to solve problems in nuclear physics, but its properties also make it a very promising dark matter candidate. The detection of axion dark matter would solve two of the biggest mysteries in physics. ADMX is an incredibly sensitive detector that functions a lot like an AM radio and tries to “hear” a particular signal from axions. We just published results from our most recent science run, where we achieved an unprecedented sensitivity to axion dark matter that makes us the first experiment to probe the most likely areas for axions. Ask us all your axion, dark matter, and science questions!

Discoveries of planets outside our solar system have burst from a trickle to a flood in recent years, transforming our understanding of the Universe. NASA’s Kepler exoplanet-hunting spacecraft and other missions have shown that the Milky Way Galaxy is teeming with at least tens of billions of planets. These exoplanets come in a variety of shapes and sizes, from smaller than Earth to larger than Jupiter, and include a small number of Earth-size planets in the “habitable zones” of their stars. Telescopes like the Hubble Space Telescope are carefully examining the atmospheric compositions of many of these alien worlds. However, the goals of imaging an Earth-size planet around another star and comprehensively understanding surface properties and atmospheric characteristics remain elusive. The launch of the James Webb Space Telescope in 2018 will help move comparative planetology forward, while astronomers are continuing to design and develop the next generation of observatories. As scientists deeply involved in this research, we welcome your questions about the current state of knowledge about the diversity of exoplanetary systems, and the challenges of direct imaging and atmospheric characterization in particular. We’re especially interested in telescope concepts under development to directly image exoplanets and search for water, ozone, oxygen, and other potential markers of habitability, and envision where these may take our understanding of exoplanets in the next decade.

The moderators of /r/philosophy are pleased to announce an upcoming AMA by Professor Debra Satz, Marta Sutton Weeks Professor of Philosophy at Stanford University and co-host of the Philosophy Talk radio program. This AMA is the fourth in our Spring 2018 AMA Series; you can find more details on all of this semester’s AMAs with philosophers by going to the AMA Hub Post. You can find all of our previous AMAs over the years by going to the AMA wiki. Professor Satz will be joining us on Monday February 19th at 12PM ET to discuss issues in political science, public policy, the ethical limits of markets and more. Hear it from her: Debra Satz I’m Debra Satz, the Marta Sutton Weeks Professor of Philosophy at Stanford University and co-host of the Philosophy Talk radio program. I grew up in the Bronx, and was the first of my family to go to college. From there, I graduated from City College of New York and received my PhD from M.I.T. where – after toying with the idea of writing on the philosophy of logic – I wrote a dissertation focusing on Marx’s theory of social progress. Although I have traveled far from where I began, my experiences growing up in the Bronx continue to influence my work and thought. My philosophical work has been broadly concerned with the economic preconditions for a democratic society of equals. But rather than approaching this question at a very high level of abstraction, I have focused on the ethics behind the creation and operation of particular markets. Markets in the abstract are models of freedom and equality. Freedom because each has the choice to enter into, or refrain from entering, any particular exchange. Moreover, because each of us is linked through countless others, no one is under the thumb of any particular person. This latter point also underwrites our equality. In theory, neither is dependent on the other and each has the right to refuse a deal which we view as unfair. But, in reality, many markets depart very far from that theory. Some markets involve agents who are asymmetrically situated: One person desperately needs a good that only the other has (think of credit markets in the developing world); or, one person has relevant knowledge that another person lacks (think of the market for used cars). Moreover, some markets involve risks that fall on others besides the transacting agent (think of exchanges that generate pollution); or markets where others are transacting on our behalf (think of child labor markets where parents transact on behalf of their children, or governments where dictators transact debt on behalf of their populations). My book, Why Some Things Should Not be For Sale: The Moral Limits of Markets develops a theory that distinguishes between ordinary markets that resemble abstract markets and what I call noxious markets. Noxious markets are characterized along four parameters: weak agency, background vulnerability and inequality of the transacting agents, harms to individuals, and harms to society. My book examines markets in body parts, commercial surrogacy, child labor and prostitution. Importantly, I argue that the fact that a market is noxious does not entail the conclusion that we should ban it. It may be possible to increase agency (by giving parties better information) or address third party harms through regulation. But a message of my work, which resonates with a long tradition of political economy (where figures such as Adam Smith, David Ricardo, Karl Marx and RH Tawney are central) is that not all markets are the same. I also have interests in the distribution of educational opportunities, where I have argued that the sharp divide policy makers and philosophers draw between adequacy approaches and equality approaches is overdrawn. A theory of distributing educational opportunity that is adequate for a democratic society will have strong egalitarian elements. In addition to pursuing my interests in education (which was my path out of poverty), I am writing a paper which examines the role of the state’s distribution of in kind goods (such as health care) for a democratic society of equals. I look forward to discussing my work with you on reddit! Links of Interest: My book: Why Some Things Should Not be For Sale: The Moral Limits of Markets.

Hi reddit, I’m a physicist at the University of Bath, UK, working on microscopy and automated instrumentation. I’m very interested in using and developing open source hardware for scientific applications – particularly microscopes. Two projects I’m working on at the moment are developing high-precision positioning mechanisms that can be 3D printed, and creating automated microscopes for analysing blood smears to diagnose malaria. The project teams include scientists and engineers from the Universities of Bath and Cambridge, and Ifakara Health Institute and STICLab in Tanzania. All the hardware we’ve developed so far on these projects is open-source, available on GitHub, for example: https://github.com/rwb27/openflexure_microscope/ I hope that, by sharing our designs, we can enable small maker spaces and engineers like STICLab (https://www.sticlab.co.tz/) to produce, and indeed customise, sophisticated products with less reliance on expensive imported goods. It also makes it much easier for people to get involved with the research project, by hacking, tweaking, or replicating our hardware for their own use. Science relies on experiments being repeatable, but often University labs are full of black boxes (metaphorically – they’re usually beige) which are expensive, hard to customise, and sealed up so you can’t see how they work. Even worse, this proprietary hardware often won’t talk to open software, making it difficult to integrate into complicated, automated experiments. There’s a growing movement of people trying to open up scientific hardware – because this is good for science, even without the cost savings that can come from 3D printing many components in your lab. This is all explained much more eloquently in the GOSH manifesto and roadmap: http://openhardware.science/gosh-manifesto/ http://openhardware.science/global-open-science-hardware-roadmap/ I’m quite new to reddit, but I guess this is the part where I stop and let you take over – I’ll be back at 10 am ET to answer your questions, ask me anything! Thanks everyone for the questions - it’s been fun! I’m signing off now, though I’ll try to keep an eye out in case there are any follow-up questions. I should also take a moment to thank my sponsors - I have the privilege of being funded to work on this project, by the UK’s Engineering and Physical Sciences Research Council (EP/P029426/1), the Royal Commission for the Exhibition of 1851, and the University of Bath.
Hi all! My name is Dr. Christopher Carroll. I am a pediatric critical care physician at Connecticut Children’s Medical Center, a Professor of Pediatrics at the University of Connecticut, and I serve on numerous committees within the American College of Chest Physicians including as trustee of the CHEST Foundation, chair of the Scientific Presentations and Awards Committee, past-chair of the Pediatric NetWork and steering committee of the Critical Care NetWork. Most of research has focused on the treatment of severe respiratory diseases in children (particularly acute asthma and bronchiolitis) and the influence of genetics on respiratory diseases in critically ill children. My name is Dr. Jayshil Patel, and I currently administer to patients, teach and conduct research as an academic intensivist for the Pulmonary and Critical Care Division at the Medical College of Wisconsin. I received training in internal medicine at the Cook County Health and Hospital System in Chicago followed by subspecialty training in pulmonary and critical care medicine at the Medical College of Wisconsin. The majority of my career has centered around a mixture of enhancing patient care, providing education and mentorship to house staff and medical students and advancing science through research, in which I primarily study the impact of enteral nutrition on critical care patient outcomes. Influenza, most commonly known as the flu, is a contagious respiratory illness caused by influenza viruses. The flu can cause mild to severe illness and at times can lead to death. Anyone can get the flu, and serious problems related to the flu can happen at any age but may have a higher risk of occurring in young children and patients 65+. We are in the heart of a particularly severe flu season and it’s important to understand the causes, symptoms and ways to treat and prevent the flu. Since the flu and the common cold are both respiratory illnesses that share very similar symptoms, it can become very tough to differentiate one from the other. We’re here to provide the facts, share the latest in research and help provide more information on how to best tackle this flu season. Just a note, we won’t be able to give specific medical advice or a diagnosis on this Reddit AMA. Conflict of Interest Disclosure: Our thoughts and opinions are our own. We will be back at 1 p.m. CT to answer your questions; ask us anything!
The mods of /r/philosophy are pleased to announce an upcoming AMA by Michael Cholbi, Professor of Philosophy and Director, California Center for Ethics and Policy, California State Polytechnic University, Pomona. This AMA is the second in our Spring 2018 AMA Series; you can find more details on all of this semester’s AMAs with philosophers by going to the AMA Hub Post. You can find all of our previous AMAs over the years by going to the AMA wiki. Professor Cholbi will be joining us on Thursday January 25th at 1PM ET to discuss issues in ethical theory, moral psychology, practical ethics, Kant and the philosophy of death and dying. Hear it from him: Michael Cholbi I’m Professor of Philosophy at California State Polytechnic University, Pomona. I work and publish in a number of area of ethics, including ethical theory, moral psychology, practical ethics, and the history of moral philosophy. Much (though not all) of my work has a Kantian flavor – but do note I’m willing to take Kant and Kantians to task when need be! (For a good overview of my work on Kant’s ethics, check out my book Understanding Kant’s Ethics). Here are some more specifics about my research: I’m perhaps best known for my work on philosophy of death and dying, including my work on suicide and grief. With respect to suicide, my views are complicated: I argue that most acts of suicide violate our Kantian duty to preserve our rational agency, but precisely because this is a self-regarding duty or duty to self, then at a social level, individuals have an autonomy-based right to shorten their lives, consistent with their moral obligations to others; that medically assisted dying is not contrary to the moral norms of medicine and that the medical profession should not monopolize access to desirable ways of shortening our lives; that, all other things being equal, mental health problems provide equally strong justifications for suicide as do ‘physical’ ailments, etc.; and that non-invasive public health measures to prevent suicide are typically defensible. Grief is an understudied phenomenon among philosophers. Much of my work here is concerned with understanding how grief can makes our lives better — why we wouldn’t find it desirable to be unable to grieve, like Meursault in Camus’ The Stranger — despite the fact that it involves pain or mental distress. In the book I’m writing, I propose that grief represents an especially fruitful opportunity to know ourselves and understand our own commitments and values more deeply. In other areas of social ethics, I write on paternalism, defending what I call the ‘rational will’ conception of paternalism, wherein paternalism is wrong because it intercedes in our powers of rational agency in various ways; on race and criminal justice, where I argue (in a forthcoming paper in Ethics) that racial bias in the administration of the death penalty in the U.S. merits its de facto abolition; and on the philosophy of work and labor, a new area of research where I’m exploring universal basic income and notions of meaningful work. As you can tell, my work is very diverse, both topically and methodologically. I try to integrate empirical work from economics, legal studies, and psychiatry into my research where appropriate. I look forward to discussing any and all of my work with the reddit audience! Links of Interest: My Stanford Encyclopedia of Philosophy article on suicide My review of Fischer and Mitchell-Yellin’s book on near death experiences A piece on grief in Four By Three A blog post on paternalism from LSE’s The Forum AMA Please feel free to post questions for Professor Cholbi here. He will look at this thread before he starts and begin with some questions from here while the initial questions in the new thread come in. Please join me in welcoming Professor Michael Cholbi to our community!
Thank you everyone who sent in questions! That was a fun hour. Must run, but I’ll come back later and address those that I couldn’t get to in 60 minutes. Means a lot to me to see all of this excitement for science. And if you missed the AMA in real time, feel welcome to pose more questions on twitter @jannalevin. Thanks again. Black holes are not a thing, they’re a place—a place where spacetime rains in like a waterfall dragging everything irreversibly into the shadow of the event horizon, the point of no return. I’m Janna Levin, an astrophysicist at Barnard College of Columbia University. I study black holes, the cosmology of extra dimensions, and gravitational waves. I also serve as the director of sciences at Pioneer Works in Red Hook, Brooklyn, a non-profit foundation that fosters multidisciplinary creativity in the arts and sciences. I’ve written several books, and the latest is titled, “Black Hole Blues and Other Songs from Outer Space.” It’s the inside story on the discovery of the century: the sound of spacetime ringing from the collision of two black holes over a billion years ago. I’m also the host of NOVA’s new film, “Black Hole Apocalypse,” which you can watch streaming online now here. In it, we explore black holes past, present, and future. Expect space ships, space suits, and spacetime. With our imaginary technology, we travel to black holes as small as cities and as huge as solar systems. I’ll be here at 12 ET to answer your questions about black holes! And if you want to learn about me, check out this article in Wired or this video profile that NOVA produced. —Janna
Welcome to our new semi-regular Science Issues Discussion. This month, the discussion topic is net neutrality and potential impacts on science, science communication, education, and and informed citizenry. Some example concerns are: How will this impact scientists’ abilities to collaborate on projects? How will this impact citizen science initiatives? Will this exacerbate the relationship between income levels and access to scientific knowledge? How will this impact science communication and journals - especially open access journals? How will this impact start-ups and smaller private scientific enterprises? To guide us in this discussion we have invited Ryan Singel (u/ryansingel2) who is a Media and Strategy Fellow at Stanford Law School and represented start-ups at a meeting with then FCC chairman Tom Wheeler about net neutrality. Ryan Singel covered net neutrality (and more) for Wired from 2002 to 2012. He left Wired to found Contextly, an engagement platform for publishers. He’s now a Media and Strategy Fellow at Stanford Law School’s Center for Internet and Society focussing on net neutrality and the CEO of Contextly. You are welcome to ask Ryan questions directly but we also invite him to engage with ongoing discussions where he can lend his expertise and share his thoughts. Science Issue Discussions are more relaxed formats than AMAs. We encourage you to bring your own personal experience - especially those of you who have flair in our sub and can speak to how this topic impacts your own field of study. Anecdotes and personal narratives are permitted. However, we still maintain strict rules about commenting and we do not permit rudeness, hateful or angry comments, bigotry, doxing, or witch hunts. Your comments should be related to the topic of the discussion and not jokes, memes, or pop culture references. No pseudoscience and this is not the place for grandstanding or big political arguments. Failure to adhere to these rules will have your comments removed and you risk being banned.
The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential environmental and human health impacts.” Experts from across academia, government and industry are here to answer questions on this topic. The research being presented at our meeting will cover topics such as how fish react when a variety of medicines get through wastewater treatment and into their environment, to what levels of detection in water is risky to human health, to how veterinary medicines given to cattle get into the environment, among others. Please do note that we are asking members of the society who represent researchers from a variety of disciplines and sectors; the answers are not official SETAC positions. We encourage discussion and debate! Just please keep it professional. For more information on SETAC see http://www.setac.org Post your question and the organizers of the conference will find someone to answer it as soon as possible. Answers to questions will be most active during the session break at 10AM-11AM EST and immediately following 12PM-2PM EST, ending at 2PM EST.
Edit: Hi everyone! Many thanks for those who were interested in this topic, I really enjoyed answering your thought-provoking questions. I am signing out now, but will try to check back later and answer a few more. Hello Reddit! I’m a chemical ecologist at Rothamsted Research in the UK. Up until the age of eight I had wanted to become a pilot, an ambition that was stopped short after a failed attempt to fly a home-made glider. However, I think it was my innate curiosity that eventually made me realise that I wanted to do something connected to nature. Endless hours a day spent in the back garden, natural history books, influential teachers and, later in life, great mentors supported me on my way to becoming an ecologist. First at the Plant Protection Institute of the Hungarian Academy of Sciences (http://marton.agrar.mta.hu/start.php?lang=en), and later at Rothamsted (https://www.rothamsted.ac.uk/). I was amazed by the dedication and focussed work of inspiring scientists who wanted to make a difference, thereby setting a standard for me. After my third level studies, I was introduced into the amazing world of semiochemicals (behaviour- and development-modifying chemicals). Since then, I have found myself immersed in this magical world of chemical communication that invisibly governs key interactions among organisms! It is fascinating stuff! I mainly work with insect pests in agro- and forest ecosystems. I identify volatile compounds from the pests’ host plants or the insects themselves. I then use these compounds to manipulate the behaviour and development of the plant, or the insect, to help keep the pest’s population under control. I recently also started to study the chemical ecology under our feet. The soil is a tough one, because it is much less accessible, and therefore harder to research, than the environment above the ground. However, when something is discovered here, it has the potential to be ground-breaking! In a world where environmental, human and food safety are fortunately becoming increasingly important, we need alternative, non-toxic ways to tackle pests, and chemical ecology research offers such solutions. The recent ban of many key pesticides is also driving the focus of plant protection in this direction. It would be great to discuss my research with you. Feel free to ask me anything! On Thursday 26th October at 4pm (BST) I will be live on Reddit Science AMA. In the meantime, you are welcome to find out more about me in a blog entry I wrote for Rothamsted’s ‘A day in the life of a research scientist’ blog series (https://www.rothamsted.ac.uk/articles/day-life-dr-jozsef-vuts).

Hi Reddit, My name is Natasha Agramonte and I am a Research Fellow at the CDC Entomology Branch and a PhD Candidate at the University of Florida. My research focuses on how insecticide resistance affects mosquito blood-feeding behavior. I recently published a study titled ‘Pyrethroid resistance alters the blood-feeding behavior in Puerto Rican Aedes aegypti mosquitoes exposed to treated fabric in PLOS Neglected Tropical Diseases. Insecticide resistance is a problem in mosquito control, because it increases disease risk, control costs, and environmental damage. Using a pyrethroid-susceptible and a pyrethroid-resistant strain of Ae. aegypti, we observed the blood-feeding behavior using fabric treated with four distinct but related insecticides. The results of this study indicated that higher amounts of pyrethroid chemicals are necessary to reduce blood-feeding behavior in the resistant Puerto Rican strain of Ae. aegypti, but interestingly the blood-feeding resistance was different (and lower!) than when the chemicals were directly applied to the mosquitoes for two chemicals: permethrin and etofenprox.

Hi Reddit! We’re the editors for Science Advances, an open access journal that accepts longer research articles (up to 6,000 words). Since our launch in February of 2015, we’ve published more than 1,500 papers and have a number of articles with tens (and even hundreds) of thousands of downloads, and hundreds of citations. As we mature as a publication, we continue our interest in areas of great scientific breakthroughs and innovation on both broad and disciplinary-specific levels. The journal is broadly organized in the areas of life and biological sciences, earth and environmental sciences, and physical and materials sciences. This month our publications range from water on the moon to the diverse interests of people who participated in the Women’s March to the internal GPS of seabirds. Feel free to ask us about what makes for a good research article, what topics we’re interested in, what questions we find most intriguing, and anything about open access. We’re also happy to chat about what makes us different and unique as an open access journal of AAAS, and what the editorial process here is like. We have editors Kip and Warren here to answer your questions as well as the managing editor Philippa Benson. What do you want to know about publishing and open access? We’ll be back at 2 pm ET to answer your questions, Ask us anything!
