Hi fellow dataviz enthusiasts! My name is Nadieh Bremer and these days I freelance as a data visualization designer, under the name of Visual Cinnamon. Since July of 2016 I’ve been doing a personal collaboration with Shirley Wu called data sketches, creating an elaborate visualization ±each month, during which I created works about the words spoken in the LotR movies, all Olympic gold medal winners, the fights in Dragon Ball Z, a “breathing” Earth and more. In 2011 I graduated as an Astronomer (still very much drawn towards the subject, either in data such as in this exoplanet visual and HR-diagram, or in design elements, such as in Royal Constellations). I then became a Data Scientist for Deloitte Consulting where I gradually discovered my passion for the visualization of data (and Self-Organizing Maps), making complex things accesible to non-experts. From December 2014 I finally decided to go heads-on into data visualization, and started freelancing in 2017. I find myself focusing on making non-standard visualizations that convey a lot of information, so people can also find their own stories beyond the general point the visual wants to make, while also being visually appealing to draw people in. But I also like to experiment with web techniques that haven’t quite found their way into dataviz, such as the gooey effect and other experiments And finally, I enjoy diving into the world of data-art every now and then with works such as The art in pi & Marble butterflies I’ll be back at 18:00 CET / 9:00am PST to answer your questions (proof that it’s me)! Update: Here now and answering questions! Update: And done! All questions answered, thanks for tuning in, hope some of the answers were helpful

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!

Hi Reddit, I’m Elijah Meeks. I wrote D3.js in Action and I just open sourced Semiotic, a data visualization framework focused on information modeling. I used to do data visualization in the digital humanities, including projects like ORBIS, Kindred Britain and the Digital Gazetteer of the Song Dynasty. Now I work at Netflix visualizing user behavior, algorithm performance and just big data more generally. Lately I’ve been pushing for the community to take a critical look at professional data visualization: how we design roles, how data visualization is seen by leadership and how we evaluate data visualization products. Proof of Life Follow me on Twitter Read my pieces on Medium Some examples of my work: My Blocks A visualization of Archer ORBIS - Geographic and Transportation Data Visualization of the Roman Empire A timeline of US Wars EDIT: Okay I came back and responded to a few more things and it was totally worth it.

Thanks for the great questions, Reddit! We’re done answering for the day and are off to finish preparations for tomorrow’s Earth Gravity Assist maneuver. Tomorrow, NASA’s asteroid-hunting spacecraft, OSIRIS-REx, will fly by Earth and use the planet’s gravitational pull to slingshot itself onto a new trajectory. This maneuver, called an Earth Gravity Assist (EGA), will put the spacecraft on course to rendezvous with a primitive, near-Earth asteroid named Bennu. The spacecraft will reach Bennu next year, map the asteroid, and collect a sample of surface material (called regolith) that will be returned to Earth for study in 2023. This mission will bring the largest sample of space material to Earth since the Apollo missions’ lunar samples. We’re a group of scientists and engineers based at the University of Arizona—home to the mission’s Principal Investigator’s office and the Science Processing Operations Center—ready to answer your questions about OSIRIS-REx, EGA, and the mission to collect some of the oldest material in the solar system. We’ll be online from 1 to 3 pm PST (4 to 6 pm EST). Ask us anything!

Hello everyone. My name is Andy Kirk and I am a UK-based freelance data visualisation specialist. I do dataviz design consultancy, run training workshops, write books, give talks, undertake research work, lecture at Imperial College and I am the editor of visualisingdata.com. I also provide data visualisation services to the Arsenal FC performance team. You can find me on the web, on Twitter, Facebook and Instagram. I launched visualisingdata.com at start of 2010 to continue learning, research and writing about the subject. It won (gold, 2015) and lost (silver, 2016) awards at the last two Kantar Information is Beautiful awards event. I tend to be known for my list-making, with my ‘Best of…’ monthly and ’10 most significant developments’ posts quite popular as well as my ‘Little of visualisation design’ #LittleVis series. I also try to compile useful data resources for folks trying to make sense of all the options out there, such as dataviz tools, the chartmaker directory and dataviz books. Since I became a freelance professional in 2011 I have focused, primarily, on providing data visualisation consultancy and training workshops – of which I have delivered over 210 public and private training events across the UK, Europe, North America, India, South Africa and Australia. You can see my past clients listed here. In July 2016, I released my second book entitled “Data Visualisation: A Handbook for Data Driven Design”, published by Sage. So that’s me in text form here’s proof that I am actually me. ** Update @ 6:30pm (BST): I’m back, let’s do this **

ACS AMA Hey Reddit folks! My name is Charley Trowbridge and I am the Director of Peer Review Operations at the ACS. Along with my group, which consists of 15 team members distributed around the country and the globe, I am responsible for the support and maintenance of the peer review system that the ACS uses for all of its journals and books, and for the administrative support of our ca. 500 worldwide editorial offices. We strive to ensure that submitted content receives swift and thorough review, and are constantly looking for ways to improve our processes and policies to make submitting to ACS journals as easy as possible, while maintaining the highest possible quality of review experience. Recently we have also dedicated ourselves to developing the ACS Reviewer Labhttps://www.acsreviewerlab.org/, which is a free online interactive course that we have developed and launched to educate researchers on the principles of quality peer-review. Anyone can take the course, which takes about four hours to complete, in total. You can go through the six modules of the course at your own pace, and have 30 days to complete it. Also, September 11-17 is Peer Review Week - follow the conversations via #PeerRevWk17 on Twitter. I have been at the ACS for 11 years, and have been involved in the development and implementation of web-based peer review for about 16 years. Before coming to the ACS I worked for many of the major science publishers in a variety of roles and capacities, and I have been involved in scholarly publishing for the past 35 years overall. I have a BA in comparative literature, with a concentration in German. I lived and worked in Germany for two years. Ask me anything about the peer review system and process at the ACS, about how we handle submissions, and about how ACS supports authors, reviewers, and editors. I’ll be back at 11am EDT (8am PDT, 3pm UTC) to start answering your questions. Logging in at 11am EDT. Logging off at 12:31pm EDT.

Hello Reddit! We are: Hakhamanesh Mostafavi: Graduate student in biology at Columbia University Molly Przeworski: Professor of biology at Columbia University Joe Pickrell: CEO at personal genomics company Gencove and professor at the New York Genome Center. We are a few of the authors of a recent paper Identifying genetic variants that affect viability in large cohorts where we sought to use biomedical data sets to learn about mutations that affect survival. This paper was covered in a number of news outlets with titles like Massive genetic study shows how humans are evolving, and there was a great discussion of the paper on r/science What does it mean for humans to still be evolving? For a species to evolve simply means that mutations—the accidental changes to the genome that happen in the process of copying DNA—are increasing or decreasing in frequency in the population over time. Our basic idea was that mutations that affect the chance of survival should be present at lower frequency in older individuals. For example, if a mutation becomes harmful at the age of 60 years, people who carry it have a lower chance to survive past 60, and so the mutation should be less common among those who do. We therefore looked for mutations that change in frequency with age among around 60,000 individuals from California (as part of the GERA cohort) and around 150,000 from the UK Biobank. Across the genome, we found two variants that endanger survival in these individuals: (i) a mutation in the APOE gene, which is a well-known risk factor for Alzheimer’s disease, drops in frequency beyond age 70, and (ii) a mutation in the CHRNA3 gene, associated with heavy smoking, starts to decrease in frequency at middle-age in men.We found genetic mutations linked to a number of diseases and metabolic traits to be associated with survival: individuals who are genetically predisposed to have highertotal cholesterol, LDL cholesterol, risk of heart disease, BMI, risk of asthma, or lower HDL cholesterol, tend to die younger than others. Perhaps more surprisingly, we discovered that people who carry mutations that delay puberty or the age at which they have their first child tend to live longer. Thanks for having us, this was a lot of fun
