“We’re From NASA”: How Citizen Science Helped Find Ultima Thule

The science world is a-twitter with excitement lately, following the recent arrival of the New Horizons spacecraft at 2014 MU69, dubbed “Ultima Thule” by popular vote. The name means “beyond the borders of the known world”, signifying Ultima Thule’s status as the most distant object ever visited by Earthly spacecraft. Ultima Thule is a dark reddish rock in the Kuiper belt, a contact binary formed by two smaller rocks coming together in what was presumably a gentle fashion.

Reaching this space snowman 6.5 billion kilometers away from Earth took brains, dedication, ingenuity and the help of an unnamed Argentinian man and his daughter.

To successfully intercept Ultima Thule, the New Horizons mission team needed to answer some questions, such as “What trajectory is Ultima Thule on?” and “Is there any space debris around Ultima Thule that will destroy our spacecraft?” Being so small (~30km diameter at its widest point), observing the spacecraft directly from this far away would be too difficult, so the team relied on data gathered during stellar occultations, i.e., when Ultima Thule passed in front of a star.

One of these occultations occurred on July 17, 2017, in the Patagonia region of Argentina. The team had already struck out twice in trying to observe Ultima Thule passing over a star: once in South Africa, and again using the airborne telescope SOFIA over the Pacific Ocean, so tension was already running high.

On this particular night, it happened to be very windy where the observation team was, which is bad news when you’re trying to hold steady focus on a tiny object that’s really far away. The team found themselves needing help to shield the telescopes they had brought with them from wind vibrations, and get the data from the star “without it jiggling around all over the place”, as planetary scientist Anne Verbiscer puts it.

Where does one find volunteers for an astronomical observation? Well, apparently even in Argentina NASA is known and loved, and help can be found just by walking into the community. “If you just started out with ‘We’re from NASA,’ people started coming out of the woodwork,” said Dr. Verbiscer. And that is how one Argentinian man and his daughter ended up spending their evening blocking the wind from a telescope using a truck, a tarp and some plywood, allowing the NASA folks to collect the data they needed to send New Horizons to Ultima Thule.

Fun with Science for the Holidays: An “Actor’s” Perspective

This past weekend, I had the opportunity to be a part of “Once Upon a Christmas Cheery in the Lab of Shakhashiri”. Bassam Z. Shakhashiri is a professor of chemistry at the University of Wisconsin–Madison who is well-known for his fun science demonstrations and a fervent dedication to public science communication. Once Upon a Christmas Cheery started in 1970 as an end-of-semester treat for Dr. Shakhashiri’s freshman chemistry class; by 1973, the Christmas lecture had become so popular that Wisconsin Public Television offered to broadcast it during Christmas week, and this collaboration has continued uninterrupted ever since.

That’s 49 years of Christmas lectures, commemorated by making indium, the 49th element, the Sesame Street-esque “sponsor” of the show. It helps that indium burns bright violet, the name of Dr. Shakhashiri’s granddaughter and hence his favorite color. The color purple made a firm foundation for many aspects of the show: The chrysanthemums frozen in liquid nitrogen were purple, as was the balloon I inflated during my spiel on air movement. Most of the set was various shades of purple, too.

When School is just a Memory: Science after College Graduation

Happy graduation! Whether you graduated last week or twenty years ago, the experience is roughly the same. As soon as you arrive on the far side of the stage, empty diploma folder under your arm, hand still sticky from the Dean’s sweaty handshake, the reality of post-academic life sets in. Perhaps grad school is on the horizon for some and others might be busy prepping for med school. For some of us, though, our years of formal education end after four and we run off to rejoice in our newfound freedom. No more exams, group projects, late nights writing papers, disapproving professors, supervisors and mentors – done with that life forever! We didn’t even bother with the GRE, MCAT, LSAT or a single “Why [insert school]” essay. Now it’s off to enjoy the Real World, which will definitely be better than college.

I’ve found, in my one year of post-college life, that sometimes you can miss academic life. You’ll occasionally look back and think, “I didn’t know how good I had it.” In particular, those of us with a pure love of learning can find ourselves unsatisfied with our prospective learning opportunities or lack thereof. We spent college soaking up mountains of knowledge–and not just from textbooks. University life gives you access to free talks from eminent thought leaders, unrestricted access to myriad scientific journals, and plenty of people around who are eager to argue about that day’s lecture in Cell Biology or Neuroscience. After college, it’s tough to fill that void.

I work at Promega (obviously), a biotech company, so I still have access to journals and there are plenty of brilliant scientists around me. However, I’m still looking for more opportunities to learn and grow. I may be out of school, but the love of science never goes away. Here are a few of my tips for everyone receiving their hard-earned science degree this spring.

Some Seriously Funny Science

The other night I was playing volleyball and, during a team huddle, made a joke that the only players working hard were those with two X chromosomes (a playful jab at the male players on my team). The only response I got was a single, delayed smile along with a bunch of blank looks. That joke certainly would have produced a better reaction among my scientific colleagues, even if that simply meant a bunch of immediate groans.

I happen to think science-minded folks like myself have a terrific sense of humor, it’s just tailored to a more niche audience since a lot of the jokes we tell may not be immediately understood by the average person. While I appreciate comedy in all forms, I delight in laughing at and making a joke related to science.

Since I don’t think I am alone, I thought I would share a few events in today’s blog that really highlight the humor that can be found in the scientific community.

BioTech Scientists through a Different Lens

When I was in grad school and pictured what a role in industry would look like, the first thing that came to my mind was a Research and Development (R&D) Scientist. My life as a grad student and as a postdoc revolved around benchwork, so that must be the case in industry too, right?

It really wasn’t until I started working at Promega that this image of a scientist in industry was completely turned upside down (in a good way). Here are some roles that a scientist can assume at Promega: Senior Scientist, Research Scientist, R&D Group Leader, Production Scientist, Technical Services Scientist, Product Manager, Strategic Marketing Manager, Client Support Specialist, Client Support Consultant, Clinical Technical Consultant, Field Support Scientist, Applications Scientist, Scientific Instructional Designer. The list can probably go on for a while, but it makes the point that there are a variety of interesting positions for scientists in the biotech industry.

Rwanda – Africa’s Next Biotech Hub

Promega sponsored a preconference workshop for grad and undergrad students at the University of Rwanda’s biotechnology campus in Huye, the capital city of Rwanda’s Southern Province.

More than twenty years after the Rwandan genocide when some 800,000 people were killed in just 100 days by ethnic extremists, Rwanda is on a path to not only healing and order, but also technological advancement. Now politically and functionally stable, which is an exception to the rule in east Africa, the country is recognizing that biotechnology is one of the key drivers to help improve the health and well being of its citizens. Rwanda is focusing on providing the resources and training needed to grow its capabilities in biotechnology, and could be on track to become an African biotech hub.

Rwanda, and its biotech push, caught the attention of Promega by way of customers working with its Belgium-Netherlands-Luxembourg (BNL) branch office. Researchers who are also African ex-patriots working at Université libre de Bruxelles (ULB), a French-speaking private research university in Brussels, Belgium, invited Promega to attend a conference in Rwanda earlier this month organized by the Society for the Advancement of Science in Africa (SASA) and the Rwanda Biotechnology Association focusing on translational science and biotechnology advances in Africa. Promega was a main sponsor of the conference along with US medical device manufacturer Medtronic. Continue reading “Rwanda – Africa’s Next Biotech Hub”

Tick, Tock! The Molecular Basis of Biological Clocks

A long time ago, before the rise of humans, before the first single celled organisms, before the planet even accumulated atmospheric oxygen, Earth was already turning, creating a 24-hour day-night cycle. It’s no surprise, then, that most living things reflect this cycle in their behavior. Certain plants close their leaves at night, others bloom exclusively at certain times of day. Roosters cock-a-doodle-doo every morning, and I’m drowsy by 9:00 pm every night. These behaviors roughly align with the daylight cycles, but internally they are governed by a set of highly conserved molecular circadian rhythms.

Jeffrey Hall, Michael Rosbash and Michael Young were awarded the 2017 Nobel Prize in Physiology/Medicine for their discoveries relating to molecular circadian rhythms. The official statement from the Nobel Committee reads, “…this year’s Nobel laureates isolated a gene that controls the normal daily biological rhythm. They showed that this gene encodes a protein that accumulates in the cell during the night, and is then degraded during the day. [They exposed] the mechanism governing the self-sustaining clockwork inside the cell.” What, then, does this self-sustaining clockwork look like? And how does it affect our daily lives (1)?

“Reverse” Molecular Reactions in DNA through Mind-Body Interventions

While my morning routine typically only involves a large cup of coffee, increasingly more Americans are beginning their days with a set of sun salutations. Sun salutations are a series of poses originating from yoga, one of the most popular types of mind-body interventions in the United States. Along with yoga, other commonly recognized mind-body interventions (MBI) include meditation, mindfulness, Tai chi, and Qigong. Despite the fact that each of these activities differ in the amount of physical effort required, they all view mental and physical health as single cohesive system.

The influence of overall mind-body intervention on health and wellness is an ancient concept that is now revolutionizing Western medicine. In the past, Western medicine has focused primarily on the health of the physical body. Yoga and meditation were viewed as beneficial, but were less likely to be recommended by clinicians as a method for relief. Now, with recent developments in gene expression analysis techniques, we have a better understanding of biological mechanisms and how they interact with psychological variables. A possible shift in clinician’s philosophies can be seen in the steady rise in the complementary health approaches of yoga, Tai chi, and qi gong1.

To completely understand how MBI affects a person’s health, we must first realize the links between stress and the conserved transcriptional response to adversity (CTRA). CTRA refers to the common molecular pattern discovered in individuals facing hardship. Whether it be in the form of diagnosis of a life-threatening disease or the death of a loved one, the characteristics of CTRA stay consistent. CTRA causes an influx in the production of epinephrine and norepinephrine. These neuromodulators then affect the production of transcription factors.
