It’s just amazing to analyze such an anomaly.”&nbsp;&nbsp;</p> <p style="margin-left:auto;">Using advanced ion and electron microscopes, Howe and the researchers observed the arrangement of carbon atoms and its variants, known as carbon isotope anomalies, and discovered the presolar graphite grain contained oxygen-rich silicates –&nbsp;something they did not expect to see.</p> <p style="margin-left:auto;">The researchers’ observation gives new insights into the conditions of a dying star. It also contradicts the scientific hypothesis that the two types of stardust material, oxygen- and carbon-rich – which are presolar building blocks in the formation of a solar system – could not form in the same nova outburst, under the same conditions.</p> <p style="margin-left:auto;">The international collaboration, which includes Howe, planetary scientists, astronomers and material scientists at the University of Arizona,&nbsp;Washington University in St. Louis, Polytechnic University of Catalonia in Spain, and Hitachi High Technologies in the U.S. and Japan, <a href="https://www.nature.com/articles/s41550-019-0757-4">published their findings today in&nbsp;<em>Nature Astronomy</em>.</a></p> <p style="margin-left:auto;">“Sometimes research is about satisfying your curiosity. One of the greatest curiosities is how the universe was formed and how life started,” says Howe. “And this weirdo particle showed us something we didn’t know before.”</p> <p style="margin-left:auto;"><img alt class="media-image attr__typeof__foaf:Image img__fid__10770 img__view_mode__media_large attr__format__media_large" height="453" src="/sites/default/files/2019-04-29-Pierre%20Haenecour%20Jane%20Howe%20Hitachi%20-resized.jpg" typeof="foaf:Image" width="680" loading="lazy"></p> <p style="margin-left:auto;"><em>Dr. Pierre Haenecour (left) of the Lunar and Planetary Laboratory at the University of Arizona and ˾ֱ Associate Professor Jane Howe, analyze images of stardust particles with Hitachi’s SU9000 low-voltage STEM/SEM electron microscope (photo courtesy of Maria Schuchardt, University of Arizona)</em></p> <p style="margin-left:auto;">Howe, who joined ˾ֱ Engineering in January, is currently using her electron microscopy expertise to&nbsp;<a href="https://news.engineering.utoronto.ca/advanced-materials-for-sustainability-meet-professor-jane-howe/">study materials to advance renewable energy</a>, and also plans to expand her work to include meteoritic materials science research.</p> <p style="margin-left:auto;">“I thought this research project was really exciting, and I’m a curious person by nature. At the time, it was just part of my job assignment, but now it’s starting to become part of my research portfolio,” says Howe.</p> <p style="margin-left:auto;">She hopes to further her collaboration with researchers at the University of Arizona. In addition, she recently began a collaboration with&nbsp;<strong>Kim Tait, </strong>an associate professor in the department of&nbsp;Earth sciences who is also the senior curator of mineralogy at the Royal Ontario Museum, to study&nbsp;<a href="https://www.rom.on.ca/en/collections-research/rom-staff/kim-tait">its collection of meteorites</a>.</p> <p style="margin-left:auto;">And, in September 2023 when the University of Arizona-led NASA OSIRIS-Rex mission returns to Earth after taking samples of carbon-rich asteroid, Bennu, Howe will be among the team of Canadian researchers to analyze its samples.</p> <p style="margin-left:auto;">“This kind of research, it’s part of a much larger debate of how life started on Earth. We all care about who we are and where we came from,” says Howe.</p> <p style="margin-left:auto;">“I’m so excited to be part of advancing our knowledge in this.”</p> </div> </div> </article> </main></div> </div> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 29 Apr 2019 17:10:29 +0000 noreen.rasbach 156475 at Twins in space: ˾ֱ expert on how space travel affects gene expression /news/twins-space-u-t-expert-how-space-travel-affects-gene-expression <span class="field field--name-title field--type-string field--label-hidden">Twins in space: ˾ֱ expert on how space travel affects gene expression</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2019-01-10-kelly-space-resized.jpg?h=afdc3185&amp;itok=JuVEZXac 370w, /sites/default/files/styles/news_banner_740/public/2019-01-10-kelly-space-resized.jpg?h=afdc3185&amp;itok=3t3iYYWc 740w, /sites/default/files/styles/news_banner_1110/public/2019-01-10-kelly-space-resized.jpg?h=afdc3185&amp;itok=_ijB_S1L 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2019-01-10-kelly-space-resized.jpg?h=afdc3185&amp;itok=JuVEZXac" alt="Photo of Scott Kelly in space"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>noreen.rasbach</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2019-01-10T10:37:04-05:00" title="Thursday, January 10, 2019 - 10:37" class="datetime">Thu, 01/10/2019 - 10:37</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Astronaut Scott Kelly during a spacewalk on Dec. 21, 2015: Astronauts on space missions experience various physiological effects (photo by NASA via Getty Images)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/christine-bear" hreflang="en">Christine Bear</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/faculty-staff" hreflang="en">Faculty &amp; Staff</a></div> <div class="field__item"><a href="/news/tags/faculty-medicine" hreflang="en">Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/genetics" hreflang="en">Genetics</a></div> <div class="field__item"><a href="/news/tags/global" hreflang="en">Global</a></div> <div class="field__item"><a href="/news/tags/nasa" hreflang="en">NASA</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/space" hreflang="en">Space</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Researchers have had a rare opportunity to see how conditions on the International Space Station translate to changes in gene expression by comparing <a href="https://www.cnn.com/2018/03/14/health/scott-kelly-dna-nasa-twins-study/index.html">identical twin astronauts</a>.

Overall, astronauts remain in excellent mental and physical health relative to the general population, even after their return from <a href="https://www.ncbi.nlm.nih.gov/m/pubmed/30514748/">long-term missions</a>. And yet, the health consequences of such missions have been recognized, including <a href="https://www.ncbi.nlm.nih.gov/pubmed/30510516">cardiovascular deconditioning</a> and vision problems, the causes for which are being investigated.</p> <p>NASA scientists are exploring how gene expression – the way DNA is converted to tissues – changes in response to the environment inside the ISS. The field of epigenetics describes mechanisms through which environmental factors, like microgravity, relatively high carbon dioxide levels and possible surges in radiation alter the way DNA is read.</p> <p>Researchers also want to know how each astronaut’s unique DNA will determine their response to the space station environment. Right now, of the 37 studies under way in the space station, <a href="https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Inve%20stigation.html?#id=1664">three focus specifically on genetic research</a>.</p> <h3>Two of a kind</h3> <p>Preliminary results of the <a href="https://www.nasa.gov/feature/nasa-twins-study-confirms-preliminary-findings">exceptional study of identical twin astronauts</a> support the idea that space travel can affect gene expression in different organs. From 2015 to 2016, astronaut Scott Kelly was aboard the ISS for a consecutive 340 days. His twin brother Mark stayed on Earth. Scott’s basic genetic code was not altered, but the environment of the space station affected the way in which this code was converted into tissue.</p> <p>According to one of the lead scientists in the twin study, Christopher Mason, these changes occurred in important biological pathways relevant to bone formation and the immune system. The gene expression changes were categorized with respect to possible risk, “as low, medium or high.”</p> <p>Low-risk changes to gene expression (approximately 93 per cent of all the changes) reset to normal when Scott returned to Earth. Possible medium- to high-risk changes didn’t reverse after six months and “are changes that we’ll want to keep an eye on,” according to Mason. For example, there are expression changes that lead to the immune system being on “high alert,” says Mason.</p> <p>Although the study of identical twins provides the best evaluation of space effects on gene expression, there are not too many twin astronauts around.</p> <p>Validation of the findings in the Kelly twins will, by necessity, involve studies in other astronauts. Right now, these validation studies are happening on the International Space Station as liquid biopsies (cell-free DNA and RNA samples from blood) <a href="https://www.nasa.gov/mission_pages/station/research/experiments/2474.html">are collected for analysis</a>. But the experiments on the twins really provided a “springboard for all of these subsequent studies,” says Mason.</p> <h3>Vision changes after missions</h3> <p>Previous studies of eye health in a group of astronauts suggest that not all astronauts will respond the same way to life on the space station. <a href="https://www.ncbi.nlm.nih.gov/pubmed/28546443">Astronaut ophthalmic syndrome</a> is a condition that affects some astronauts. These ocular changes are classified by NASA “<a href="https://www.nasa.gov/mission_pages/station/research/experiments/1255.html">as a significant risk for human space travellers</a>,” and include changes to the lens and shape of the eye.</p> <figure class="align-left zoomable"><a href="https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img alt sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" src="https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=237&amp;fit=clip" srcset="https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=614&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=614&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=614&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=772&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=772&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/252972/original/file-20190109-32127-34i8ja.png?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=772&amp;fit=crop&amp;dpr=3 2262w"></a> <figcaption><em><span class="caption">Pre-flight images of normal optic disc.

On analysis, the research findings suggest that each astronaut’s genetic background plays a role in determining their eyes’ vulnerability, or epigenetic response, to detrimental triggers in the space station.</p> <h3>Space eyes and Earth wombs</h3> <p>This research means that certain astronauts could be warned of their personal risk of developing vision problems during long space missions. Better yet, personalized preventive measures or personalized medicine could be discovered and implemented for those with the greatest risk of disease.</p> <p>“Virtually all the work that NASA does has implications for the general population,” says Smith.</p> <p>Ophthalmic Syndrome in astronauts is related to another, much more common health problem here on Earth. It turns out that the same genetic variants and changes in serum factors that are associated with ocular problems in astronauts are also connected to <a href="https://www.mayoclinic.org/diseases-conditions/pcos/symptoms-causes/syc-20353439">polycystic ovary syndrome</a> (PCOS), a form of infertility in women.</p> <p>PCOS affects up to 10 per cent of women. A genetic component for this syndrome was previously suspected.</p> <p>Genetic and epigenetic studies in astronauts promise to provide astronauts with personalized medical interventions while in space. And they could also provide those of us on Earth with potential therapies.<!-- Below is The Conversation's page counter tag.

And we will need to be able to interpret huge amounts of data, which is where machine learning and artificial intelligence will be essential.”</p> <p>With all of these possibilities still to explore, Sherwood Lollar and the committee have recommended that the search for life take a variety of forms of life into consideration.&nbsp;</p> <p>“We need to go broad in thinking about the search for life in the universe. There might be oxygen in a planet’s atmosphere, but that assumes life will be like life on Earth, resulting from photosynthesis.&nbsp;But life can survive through other metabolic strategies.”</p> <p>She points out that life on Earth has been dependent on oxygen only for the past 2.5 billion of the planet’s 4.5 billion years.&nbsp;Before that, “we had lots of life, but no free oxygen in the atmosphere.&nbsp;And that’s important to realize – planets evolve.&nbsp;At one point, Mars was probably more habitable than Earth.&nbsp;We need to look at that evolution with other planets.”</p> <p>So the goal in going broad in the search is to “keep the blinkers off and consider the huge variety of lines of evidence that might be important to really nail down the question.”</p> <p>Another important direction for future research is to explore what is going on beneath the surface of planets. Part of the excitement around the discovery of the ocean deep under the surface of Europa, a moon orbiting Jupiter,&nbsp;is that life underground has been discovered on Earth, too.&nbsp;</p> <p>“One of the reasons I wanted to be a scientist was the discovery on the ocean floors in the 1970s that life down there was not driven by the sun’s energy,” says Sherwood Lollar. “It was not photosynthetic life, but life dependent on chemicals.</p> <p>"Hydrothermal vents mixed with ocean waters to produce chemical energy and it was discovered that microbes in those systems can live in the deep parts of this planet off of that chemical energy.&nbsp;And it could then sustain higher order organisms like tubeworms.&nbsp;And it’s since been found that life that lives on chemicals is not just on the ocean floors, but also the continental subsurface.”</p> <p>And if these forms of life – odd to us, but still life – can happen in Earth’s subsurface, could they happen in the deep parts of other planets?</p> <p>Consider these discoveries:</p> <ul> <li>In July, researchers found what they believe to be a lake under the southern polar ice cap of Mars.&nbsp;Water is a key component of the life we know.&nbsp;“This really qualifies as a body of water. A lake, not some kind of meltwater filling some space between rock and ice, as happens in certain glaciers on Earth,” Roberto Orosei of the Italian National Institute for Astrophysics told the BBC.&nbsp;</li> <li>The discovery of thousands of exoplanets – planets outside our solar system – by the NASA Kepler spacecraft increased the possibility for life elsewhere, especially those exoplanets at the special distance from their star in a habitable zone (that is, an area that has the right conditions for life).&nbsp;Planets in our solar system have moons; now astronomers are theorizing that exoplanets must also have moons, thus increasing the possibility for life.</li> </ul> <p>While the report pushes exploring via an outside-the-box focus, Sherwood Lollar also emphasizes that “the committee is not recommending that space scientists and agencies do everything.”&nbsp;In fact, she says, it is essential to strategize and to plan carefully and to ensure that governments, research institutions and agencies work closely together on how to conduct the search for life.&nbsp;</p> <p>“It’s a very human report in that sense.&nbsp;It’s about teamwork.&nbsp;It isn’t a solitary, ivory tower kind of exercise.&nbsp;Scientists have to be deeply engaged in their own communities and with the broader public.&nbsp;That’s how we do our best work in any area of research.”</p> <p>But how important is this search for life elsewhere?&nbsp;Wouldn’t the high expenditures associated with space research be better spent on the problems more directly associated with life on Earth?&nbsp;</p> <p>“It’s an excellent question and one I ask myself.&nbsp;So I say this:&nbsp;Astrobiology is about the study of life in the universe, which means it is about life on Earth.&nbsp;We need to take a broad view of the scientific enterprise and recognize that the search for life off Earth can have important ramifications for what we do to keep this planet habitable.&nbsp;Life will persist for us.&nbsp;The question is what will the quality of that life be?&nbsp;</p> <p>“So if you care about this planet, there are aspects of astrobiology that are deeply integrated in the health of Earth.&nbsp;It’s not an either-or proposition.&nbsp;It’s about broad-scale thinking about how planetary systems are linked.&nbsp;And that becomes more vital by the day with climate change on this planet.”</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 20 Dec 2018 05:00:00 +0000 noreen.rasbach 149236 at ˾ֱ astrophysicist teams up with NASA, uses sound to showcase latest galactic discovery /news/u-t-astrophysicist-teams-nasa-uses-sound-showcase-latest-galactic-discovery <span class="field field--name-title field--type-string field--label-hidden">˾ֱ astrophysicist teams up with NASA, uses sound to showcase latest galactic discovery</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/gamma-ray.jpg?h=afdc3185&amp;itok=KsujK0TP 370w, /sites/default/files/styles/news_banner_740/public/gamma-ray.jpg?h=afdc3185&amp;itok=wIzjcRrb 740w, /sites/default/files/styles/news_banner_1110/public/gamma-ray.jpg?h=afdc3185&amp;itok=YMq2BWzv 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/gamma-ray.jpg?h=afdc3185&amp;itok=KsujK0TP" alt="Gamma ray visualization"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Romi Levine</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2018-07-12T12:07:36-04:00" title="Thursday, July 12, 2018 - 12:07" class="datetime">Thu, 07/12/2018 - 12:07</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">The detection of gamma rays coming from a black hole has helped scientists understand one of the universe's mysteries (illustration by NASA/DOE/Fermi LAT)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/romi-levine" hreflang="en">Romi Levine</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/astronomy-astrophysics" hreflang="en">Astronomy &amp;

I wasn't sure how I would fit in at a conference for visualizers since I work mainly with sound, but it worked out perfectly. I happened to talk to the team from NASA who were gearing up for the big announcement, and they had an animation of the blazar's gamma rays being detected that was begging to be heard. They sent over the data, and I finished it with my collaborator Andrew Santaguida in the hotel room that evening. Since then we've been talking to other teams at NASA about other projects and about ways to make astronomy more accessible to the visually impaired.</p> <p><strong>What is a blazar?</strong></p> <p>Almost all galaxies have supermassive black holes at their centres, and sometimes we catch them feeding on gas, dust, and stars as they spiral in towards oblivion. All of this energy in such a small space launches a powerful jet at near light speed out of the black hole's North and South poles. When this jet is pointed straight at Earth, we call it a blazar. This would of course be deadly if we were anywhere near the blazar, but they're typically very far away. This one is almost four billion light years away.</p> <p>Scientists have been watching this one continuously for over 10 years, and in 2017, it flared with an extreme burst of energy lasting several months. It must have been hungry.</p> <p>The energy released by the whirlpool of gas and the jet creates light at many different wavelengths (radio, microwave, infrared, visible, UV, X-ray, gamma rays) which we can detect with different types of telescopes. This time, scientists have also detected neutrinos from the blazar, which are very light fundamental particles that don't like to interact with other particles. Billions of these pass through you every second, but you'd never know it.</p> <p><img alt="Matt Russo" class="media-image attr__typeof__foaf:Image img__fid__8826 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Russo-750-x-500.jpg" style="width: 750px; height: 500px; margin: 10px;" typeof="foaf:Image"><br> <em>Matt Russo combined his passions of astrophysics and music to create sounds from the movement of the cosmos (photo by Romi Levine)</em></p> <p><strong>What goes into creating the sounds for this particular phenomenon?</strong></p> <p>Gamma rays are so energetic that they strike the detector one at a time, like light-speed pebbles hitting the surface of a pond. We can hear them being detected by playing a raindrop sound for each gamma ray as it's detected while letting the energy of the gamma ray control the pitch of the raindrop. The highest energy gamma rays are heard as the highest pitched notes.</p> <p><strong>How does it feel having SYSTEM&nbsp;Sounds featured on a world stage like this?</strong></p> <p>Working with NASA has been a dream of mine for a long time, but I always thought it was out of reach since my scientific research was never focused on space missions. Since I started exploring the universe through sound, I realized that I could help communicate the data gathered by NASA in new ways that would help reach new audiences. Sound gives everyone, including the visually impaired, a visceral and affective way to experience and learn about the cosmos. And there's never going to be a shortage of astronomical data waiting to be heard.</p> <p><strong>Will you be working on creating sounds for other parts of this discovery?</strong></p> <p>This discovery is exciting because scientists have observed the same system with two completely different types of “eyes.”&nbsp;In addition to the many different wavelengths of light, they've also detected particles that were ejected from an explosion happening almost four billion light years away. My goal is convert each one of these signals into the separate instruments, or parts, of the complete blazar orchestra.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 12 Jul 2018 16:07:36 +0000 Romi Levine 138730 at One small step for man, one giant leap for these ˾ֱ engineering students /news/one-small-step-man-one-giant-leap-these-u-t-engineering-students <span class="field field--name-title field--type-string field--label-hidden">One small step for man, one giant leap for these ˾ֱ engineering students</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/NASA-group-shot-%28for-web-embed%29.jpg?h=15c9ad5d&amp;itok=Yt4kYJXo 370w, /sites/default/files/styles/news_banner_740/public/NASA-group-shot-%28for-web-embed%29.jpg?h=15c9ad5d&amp;itok=hUguHEyJ 740w, /sites/default/files/styles/news_banner_1110/public/NASA-group-shot-%28for-web-embed%29.jpg?h=15c9ad5d&amp;itok=5zS_BKrs 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/NASA-group-shot-%28for-web-embed%29.jpg?h=15c9ad5d&amp;itok=Yt4kYJXo" alt="NASA group photo "> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>geoff.vendeville</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2017-05-24T16:38:23-04:00" title="Wednesday, May 24, 2017 - 16:38" class="datetime">Wed, 05/24/2017 - 16:38</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Kevin Wang, Haroon Dawood, Stephanie Gaglione, Kate Lonergan, Jason Martins and Madhushan Perera visited a NASA facility in Mountain View, Calif. after researching a process for making acetic acid on Mars (photo courtesy Stephanie Gaglione) </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/geoffrey-vendeville" hreflang="en">Geoffrey Vendeville</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Geoffrey Vendeville</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/faculty-applied-science-engineering" hreflang="en">Faculty of Applied Science &amp;
