Tomorrow marks 5 years since the Curiosity rover’s dramatic landing on the red planet! The rover’s Sample Analysis at Mars (SAM) instrument suite onboard Curiosity is the most complicated instrument NASA has ever sent to another planet. SAM is designed to measure the composition of the atmosphere and solid samples inside Gale Crater on Mars, and help scientists assess the habitability (could a certain place support life?) of environments recorded in in rocks in Gale Crater. The SAM team has made many amazing discoveries, including finding evidence of a habitable environment – a place that life (think tiny microorganisms, not dinosaurs) could have survived if it had been in that spot on Mars, millions of years ago. SAM also detected the first organics (building blocks of life) on Mars, known to have originated on this planet. We’re a group of scientists and engineers from the SAM team, ready to answer your questions about Mars and SAM. We’ll be online from 1:00 to 2:00 pm EST and we will sign our answers. Ask us anything! Paul Mahaffy, SAM Principle Investigator, Director of Solar System Exploration Division, NASA Goddard Space Flight Center Charles Malespin, SAM Deputy Principle Investigator, NASA Goddard Space Flight Center Jen Stern, Planetary Scientist, NASA Goddard Space Flight Center James Lewis, Postdoctoral Fellow, NASA Goddard Space Flight Center Brad Sutter, Planetary Scientist, NASA Johnson Space Flight Center Greg Flesch, Instrument Engineer, NASA Jet Propulsion Laboratory Peter Martin, PhD student, CalTech/NASA Jet Propulsion Laboratory Doug Archer, Planetary Scientist/NASA Johnson Space Center We have now been on Mars for 5 years - WOW.

That’s all we have time to answer now! Thanks for all your pulsar related questions. You can stay up-to-date on the mission here: https://www.nasa.gov/nicer. And learn more technical information about NICER here: https://heasarc.gsfc.nasa.gov/docs/nicer/. Pulsars are rotating “lighthouse” neutron stars that began their lives as stars between about seven and 20 times the mass of our sun. They spin hundreds of times per second, faster than the blades of a household blender and they possess enormously strong magnetic fields, trillions of times stronger than Earth’s. For the first time, NASA has a mission to study pulsars using X-ray technology to uncover mysteries of the cosmos while paving the way for future space exploration. This two-in-one mission is called NICER-SEXTANT and it’s currently aboard the International Space Station. NICER (the Neutron star Interior Composition Explorer) uses 56 telescopes to study the structure, dynamics and energetics of these spinning neutron stars. What makes up their cores is not known, but if these super-dense objects were compressed much further they’d collapse into black holes. SEXTANT (the Station Explorer for X-ray Timing and Navigation Technology) uses NICER’s observations to test - for the first time in space – technology that uses pulsars to create a GPS-like system. This technology could support spacecraft navigation throughout the solar system, enabling deep-space exploration in the future.

*** THIS AMA IS NOW OVER, BUT I WILL CHECK BACK FROM TIME TO TIME TO ANSWER ADDITIONAL QUESTIONS. THANKS TO EVERYONE WHO PARTICIPATED. I WISH YOU CLEAR SKIES ON AUGUST 21! *** I hope you’ve got plans to experience the total solar eclipse that will cross the United States on August 21. It will be a mind-blowing, awe-inspiring, not-to-be-missed spectacle! I’ve been chasing total eclipses since I saw my first, in Aruba, in 1998. It was such a moving, addictive experience that I just had to repeat it. (You can read about my obsession/hobby here and here.) I also became fascinated with the history of eclipses, which led me to write my new book, American Eclipse: A Nation’s Epic Race to Catch the Shadow of the Moon and Win the Glory of the World. My book tells the true story of the total solar eclipse of July 29, 1878, which crossed America’s western frontier, from Montana Territory to Texas. In the nineteenth century (and even today), total eclipses were keenly important for astronomers, enabling them to probe the outer reaches of the sun and the inner reaches of the solar system. In 1878, many of the era’s great scientists traveled to Wyoming and Colorado to conduct their studies in the midday darkness. American Eclipse focuses on three remarkable individuals. Thomas Edison, age 31 and a recent celebrity due to his invention of the phonograph, traveled to Wyoming with a new device (the tasimeter) to study the sun’s corona. James Craig Watson, an astronomer at the University of Michigan, used the eclipse to search for a mysterious planet called Vulcan, which scientists believed circled the sun within the orbit of Mercury. And Maria Mitchell, professor of astronomy at Vassar College, used the eclipse for political/social purposes. She assembled an all-female expedition to Denver, to demonstrate to a skeptical public that women could equal men as scientists. I love to talk about solar eclipses! Ask me about the eclipse of 1878, the upcoming one on August 21, or anything else. I can also offer eclipse-viewing advice. I recently gave a TEDx talk about eclipse chasing, and it’s now online here. And I wrote a blog post about the August 21 eclipse for Scientific American here. I should also mention that my friends at NOVA PBS will be producing a live broadcast on Facebook during the eclipse from Irwin, Idaho. It’ll be hosted by science journalist Miles O’Brien—follow them on Facebook to get more information and updates. —David
ACS AMA Hi Reddit! My name is Donna Huryn. I am a medicinal chemist at the University of Pittsburgh’s School of Pharmacy and have an adjunct appointment at the University of Pennsylvania’s (Penn’s) Chemistry Department. I received my Ph.D. in Organic Chemistry at Penn, then spent the first part of my career as a medicinal chemist in the pharmaceutical industry, working on inventing drugs to treat HIV, cancer, Alzheimer’s disease and other CNS disorders. In 2004, I moved to academia. Currently we work on medicinal chemistry projects focusing on new treatments for cancer and kidney disease. I am PI of the University of Pittsburgh Chemical Diversity Center – we are a member of NCI’s Chemical Biology Consortium (https://next.cancer.gov/discoveryResources/cbc.htm). This consortium brings together experts in multiple disciplines to focus on drug discovery for cancer, with the goal of advancing compounds into Phase I clinical trials. Our group in Pittsburgh contributes our medicinal, synthetic and computational chemistry expertise to various projects; other centers bring expertise in biological assays, biophysics, pharmacokinetics and animal models, among others. I also am one of the Associate Editors of ACS Medicinal Chemistry Letters (http://pubs.acs.org/journal/amclct), which publishes short, urgent communications in all areas of medicinal chemistry. Ask me anything about medicinal chemistry / drug discovery in academia. I’ll be back at 12pm EDT (9am PDT, 4pm UTC) to answer your questions. [EDIT] - Hello Reddit! Thanks for the great questions so far - looking forward to a stimulation hour [EDIT] - Thanks Reddit! It was a great hour. I am signing off now, but will try to come back to answer a few other questions later in the day.
Hi Reddit, My name is Ben Halpern and I am a Professor at the Bren School of Environmental Science and Management at UC Santa Barbara and Director of the National Center for Ecological Analysis & Synthesis. My research focuses on a range of issues and questions related to effective and efficient protection and sustainable use of marine species and habitats. My colleagues and I recently published an article titled Drivers and implications of change in global ocean health in the past five years in PLOS ONE. In this paper we report five years of annual assessment of the health of the ocean in all 220 coastal countries and territories around the world, tracking how 10 different broad goals are doing and what is driving changes in those goals. Most notably we found that many countries have improved their overall score by substantially increasing the amount of marine protected areas, while many other countries have seen scores decline due to unsustainable management of fisheries and other ocean resources. I will be answering your questions at 1pm ET from the ESA 2017 Annual Meeting – Ask Me Anything!
Edit 12:46 PM ET: We are signing off! Thanks so much for all your questions. Remember to check out eclipse2017.nasa.gov/safety to make sure you are ready to watch the eclipse safely! Happy eclipse watching! Edit 11:04 AM ET: We’re live! On Aug. 21, 2017, all of North America will have the chance to see a partial solar eclipse. Along a narrow, 70-mile-wide track called the path of totality, the Moon will totally block the Sun, revealing the Sun’s comparatively faint outer atmosphere – the corona. Total solar eclipses like this are a rare chance for solar scientists to study this region of the Sun, since we can’t ordinarily see it from the ground or with satellite instruments. The sudden blocking of light also gives Earth scientists a rare chance to track how Earth’s atmosphere responds to the Sun’s radiation. Find out more about NASA’s eclipse science (and how to watch the eclipse) at eclipse2017.nasa.gov. Noah Petro I first became interested in Geology as a student at Fox Lane High School in Bedford, NY. It was while I was a student at Bates College that I was introduced to the field of planetary geology. Following my PhD work at Brown University I came to NASA Goddard as a NASA Post-Doc. Alexa Halford I am a contractor at NASA Goddard. Throughout my education I have been lucky to work at JPL NASA looking at Uranus’s moons and study Saturn on the Cassini mission at the South West Research Institute. Today I stick a bit closer to home studying the Earth’s magnetic field and its space weather phenomena. Mitzi Adams I am a solar scientist for NASA’s Marshall Space Flight Center (MSFC), where I study the magnetic ﬁeld of the Sun and how it aﬀects the upper layer of the solar atmosphere, the corona. With a professional interest in sunspot magnetic ﬁelds and coronal bright points, friends have labelled me a “solar dermatologist”. Bill Cooke The head of NASA’s Meteoroid Environment Office, I help NASA in placing meteoroid protection on spacecraft and construct meteor shower forecasts for unmanned space vehicles and the International Space Station. While a graduate student at the University of Florida, I worked on instruments flying on board balloons, the Space Shuttle, Giotto (European mission to Halley’s Comet), and LDEF. After obtaining my PhD in Astronomy, I came to work at Marshall Space Flight Center as a member of the Space Environments Team, where I became an acknowledged expert in meteors and meteoroids. I am one of the many NASA astronomers interacting with the public on the upcoming solar eclipse. Jay Herman I am an atmospheric scientist working on several projects. Two of them are of interest to the eclipse or other atmospheric questions. 1) The Pandora Spectrometer Instrument that measures the solar spectrum and derives the amount of trace gases in the atmosphere, such as ozone, nitrogen dioxide, and formaldehyde, and 2) The DSCOVR/EPIC spacecraft instrument that observes the entire sunlit globe from sunrise to sunset from the Earth-Sun Lagrange-1 point (1 million miles from earth). We derive both atmospheric and surface properties from EPIC, and we will see the Moon’s shadow during the upcoming eclipse. Guoyong Wen I am an atmospheric scientist interested in the way radiation passes through the atmosphere. The experiment we are planning to perform is a combination of theory and measurements to see if they match. For this purpose we are using an advanced radiative transfer calculation in three dimensions and measurements from the ground and a spacecraft. Hopefully, the calculations and data will match. If not, we can learn about whatever may be missing. The result will be improved calculation capability. Edit 9:18 AM ET: Added Jay Herman’s bio Edit 11:11 AM ET: Added Guoyong Wen’s bio
My name is Dr. Gerard A. Silvestri. I’m an international expert in lung cancer and interventional pulmonology. I am the President of the American College of Chest Physicians, the George Sr. and Margaret Hillenbrand Professor of Thoracic Oncology, and Vice-Chair of Medicine for faculty development at the Medical University of South Carolina in Charleston. I am a writer and editor of the American College of Chest Physicians lung cancer guidelines; I’ve authored more than 200 scientific articles, book chapters, and editorials; and have had the opportunity to serve on multiple editorial boards of medical journals, including the journal CHEST®. My passion to find new treatments and create guidelines for lung cancer is truly to help inform the public on a disease that takes the lives of many annually and assist in any way I can. Lung cancer, the second most common cancer in both men and women, is responsible for nearly one in five cancer deaths annually. There are many factors we come across daily that can cause lung cancer, including: air pollution, exposure to radon, aging, history of cancer in other parts of the body, secondhand smoke, and air pollution, and lung cancer can even run in families. While smoking is the number one cause of lung cancer, as it accounts for 80% to 85% of all lung cancer cases, we need to change the viewpoint that lung cancer is something that patients bring onto themselves. There are several factors that play into lung cancer, and many patients who receive this diagnosis are, in fact, nonsmokers. There are two types of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Non-small cell lung cancer (NSCLC) represents 80% to 90% of all lung cancer cases each year, while small cell lung cancer (SCLC) accounts for 10% to 20% of cases and tends to grow more quickly than NSCLC. Due to the various types of the disease, there is no one-size-fits-all method to treating lung cancer. Different types of lung cancer often behave differently in the body, and treatment decisions are normally based on the patient, the type of cancer they have, and what is known as the stage of cancer. I’d love to share information about the barriers and the diagnosis and treatments in lung cancer and hope I can leave you with some insight on the disease and future advancements to come. I will be back at 1 pm ET to answer your questions, ask me anything!
My most recent column (https://undark.org/article/soy-formula-babies-endocrine-disruptor/) looked at soy formula (and other soy products) which contain a remarkably high level of hormonally active compounds called phytoestrogens. I was interested in the idea that by feeding soy to babies - a constant diet at an age critical in human development - we might be running an inadvertent experiment on those children, perhaps alerting their reproduction systems. The scientists I talked to agreed that that’s a real possibility. There are studies showing that soy diets can affect gene expression in the vaginal cells of female girls, for instance, that there are other longer term studies showing changes in menstruation and other effects. It’s an issue I’d like to follow further. Part of the reason I was interested in that aspect of soy exposure is that I’m a toxicology writer. I’ve been researching and writing about toxic substances for a decade, as the author of The Poisoner’s Handbook, but also as a blogger for Wired and for The New York Times, where I wrote an online column called Poison Pen. I started out being very focused on acute toxicity but I’ve more recently become interested in low-dose toxicology - the question of what chronic exposure to a very low dose of a compound (say arsenic in rice or drinking water) means in terms of public health. The question of every day exposures and how we navigate them really fascinates me and is part of my current book project, which follows the story of America’s first great food safety chemist at the turn of the 20th century. I’m here today from 1 pm-3:00 pm EST to answer questions about chemical exposures in our everyday life, questions of natural versus synthetic compounds, and when it’s worth paying attention. Looking forward to hearing from you!
Happy Eclipse Day r/science! We’re here early to answer any last minute questions you might have about today’s historical event. Here are your AMA eclipse chat hosts: Alexa Halford is a heliophysics scientist originally from Chippewa Falls WI (go Pack go!). She is a prime example of what happens when you go to college in MN and take up space… You become a space physicist. Because she got her PhD in Oz, you sometimes hear her say x,y, zed instead of x,y, zee. Although she has worked on science questions throughout the solar system, today she sticks a bit closer to home studying the Earth’s magnetic field and the impacts of space weather events. She was part of a huge NASA AMA yesterday on the eclipse with a bunch of scientists posting as /u/NASASunEarth. Angela Fritz is The Washington Post’s deputy weather editor and an atmospheric scientist who hails from the city of rock and roll and burning rivers – Cleveland, Ohio. She knew from a young age that weather was her true calling. After receiving a B.S. in meteorology from Valparaiso University and an M.S. in earth and atmospheric science from the Georgia Institute of Technology, Angela worked as a meteorologist at CNN in Atlanta and Weather Underground in San Francisco. When she’s not forecasting hurricanes or reading the latest climate science papers, Angela enjoys outdoor adventures, public transportation, and Oxford commas. We’re going to get started at 10 a.m. ET so get those questions ready! AMA! Proof EDIT: And that’s a wrap for now! We may come back later to answer additional questions, but in the meantime, enjoy this historic day, be safe! And if you want more info, follow live coverage from The Washington Post, who is featuring coast-to-coast coverage and a livestream. EDIT 2: One more link: Here is every total solar eclipse happening in your lifetime. Enter your birth year and we’ll tell you when and where.
Hi Reddit, My name is Johannes Hegemann and I am Professor of Microbiology and Head of the Institute for Functional Microbial Genomics at the Heinrich-Heine-University in Düsseldorf, Germany. And my name in Katja Mölleken and I am a Senior Postdoctoral Fellow at the Institute for Functional Microbial Genomics at the Heinrich-Heine-University in Düsseldorf, Germany. Our research focuses on the molecular mechanisms that enable the pathogenic bacteria Chlamydia trachomatis and Chlamydia pneumoniae to infect their human hosts. This month, we published a study titled “Acquisition of Rab11 and Rab11-Fip2 – A novel strategy for Chlamydia pneumoniae early survival” in the journal PLOS Pathogens. Infection begins when the chlamydiae recognize specific receptors on their target cells, which triggers uptake of the bacteria. Once inside the cell, they establish a membrane-bound compartment termed an inclusion, in which they multiply before being released to infect new human cells. In our study we found that the nascent chlamydial inclusion actively recruits specific host proteins called Rab proteins into its membrane. These proteins define the inclusion as a so-called recycling endosome vesicle, within which the Chlamydiae hide out, so as to avoid degradation by the host cell’s waste disposal system, the lysosome. Our findings help to understand how Chlamydiae establish the intracellular niche which is essential for their survival and release. We will be answering your questions at 1pm ET – Ask us Anything!
We are SynTouch: the world leader in the technology of human touch. We invented the only sensor in the world that endows machines with the ability to replicate the human sense of touch. We call this emerging field Machine Touch. Like machine vision, it requires a combination of sensors and algorithms to take a human sense, capture it and allow us to do useful things with tactile information. One core application of our technology is quantifying dimensions of touch - we’ve created a taxonomy called the SynTouch Standard® that consists of fifteen dimensions humans feel. The information is captured by our BioTac Toccare® which Automakers, Apparel and Consumer Electronics companies use to define and improve the haptics of their products. Analogous to the use of digital color meters to capture RGB values and drive product manufacturing decisions to ensure they ‘look right’, our technology provides information to ensure products ‘feel right’. Our technology also functions as the input for haptic displays for VR and telerobotics. This allows us to drive haptic displays with real-world data for anything from a surgical robot to a gaming device – and we’ve worked with both! We’re also pursuing long-term projects to command robotic hands with tactile sense and reflexes. Our sensors allow robot hands to handle fragile objects better than currently available systems – one prime use case that we’re pursing now deploying this technology in prosthetics to allow amputees to handle fragile objects without dropping or crushing them. SynTouch was founded in 2008 by Professor Gerald Loeb, and Ph.D. students Matthew Borzage, Jeremy Fishel, and Nicholas Wettels who were at the University of Southern California. We’ve been recognized by Popular Mechanics, The Robot Report, and the World Economic Forum… Happy to answer more questions, but we’re getting busier with foot traffic right now. Thank you for your interest!
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!
Hi Reddit, my name is King-Wai Yau, and I’m a neuroscientist at the Johns Hopkins University School of Medicine studying sight and smell! I started out in medical school at the University of Hong Kong but soon switched back to basic science and came to study in the U.S I have been studying vision for over 40 years, focusing on its first step, in which light interacts with the rod and cone receptor cells of the retina, initiating a complex biochemical/biophysical process which your brain eventually interprets as vision. However, we now know that additional photoreceptor cells beyond the rods and cones you learn in school actually exist in the retina. These newly found cells mediate eye functions unrelated to creating images, like constricting your pupil in response to changes in light. These non-rod/non-cone photoreceptors are important for helping us appreciate the progress of the day and, for example, in enabling us to get over jet-lag when traveling across time zones. Recently, my research has focused on understanding how light-induced pupillary constriction in mouse eyes can occur without the brain. Unlike in humans, mice’s pupils can constrict without an obligatory connection to the brain because light-detecting pigment, present in the iris’ sphincter muscle, responds directly to light. These findings shed light on the evolutionary path of the pupillary light reflex in vertebrates, which is essential for regulating light entry into the eye especially under bright conditions. Outside of the lab, although I hardly watch any commercial television, I would compulsively put aside work in the evening to watch Nature and Nova programs when they come up on Public Television. Any knowledge about biology, physics and chemistry is fair game to me! Check out my latest research here I’ll be back at 1pm ET today to answer your questions.
Every day I work on the cutting edge of science and technology and I love it.

Have a question on the latest in active imaging research? Are you looking to make your own impact on the science community? I will be online at 1:00 pm to answer your questions – Ask Me Anything!
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
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.
