How To Make Medicine on Mars

Posted on by Darcia Schweitzer

Today NASA’s InSight lander will touch down on Mars. InSight, which launched on May 5, is NASA’s first Mars landing since the Curiosity rover in 2012. The lander will begin a two-year mission to study Mars’ deep interior, gathering data that will help scientists understand the formation of rocky planets, including Earth.

While every spacecraft that reaches Mars offers more knowledge of the Red Planet, a lot of the excitement is fueled by hopes that someday these missions will bring humans to Mars and enable us to start colonies there. While this goal seems very distant, tremendous progress is being made. Scientists around the globe are making incremental discoveries that will lead to the advances necessary to make colonization of Mars a reality.

I had the pleasure of meeting one team of scientists doing just this—eight high school students from iGEM Team Navarra BG. I met the team and their advisors at the 2018 iGEM Giant Jamboree, where they presented their synthetic biology project, BioGalaxy, as part of the iGEM competition. The problem they aimed to solve is key to helping humans stay on Mars for an extended period of time—how do you take everything you need when there isn’t enough room on the spacecraft?

Virtual Reality Is Changing How We Experience Science

Posted on by Mariel Mohns

The South Pole was exactly as I expected—snowy and barren, apart from the giant research station in front of me. Suddenly, I got a notification in my communication system that there was a strong signal coming from the sky. I looked up and changed the visual display settings of my goggles to find stunning views of the Solar System, all the way past Pluto. My heads-up display told me that I’ve discovered a subatomic particle, called a neutrino, that flies through the fabric of space at nearly the speed of light. I wanted to find the source of this neutrino, so I switched my display to X-ray vision. The signal brightened, and the source was revealed—a massive black hole. I captured as much data as possible so I could report back to the lead scientist on the project. What an exciting afternoon of research!

Okay, I’ve never actually been to the South Pole, but I experienced this event in virtual reality at a conference expo booth for the National Science Foundation. This experience put me in the shoes of an astrophysicist working at the IceCube Neutrino Detection Facility, operated by UW-Madison researchers. As someone who specializes in the life sciences, I had the opportunity to learn more about an area outside my expertise—the fascinating world of particle physics.

VR headsets offer immersive experiences for entertainment, education, training, and more.

Most people think of augmented reality (AR) and virtual reality (VR) in the context of gaming or entertainment. You’ve likely had a casual AR experience if you’ve ever given yourself a flower crown in Snapchat, or hunted for Charmander at your local park with the Pokémon GO app. Yet, as I experienced at a conference several weeks ago, AR and VR can have massive implications for education and training experiences in the sciences.

In a Perfect World, Bacteria Wins

Posted on by Jordan Villanueva

iGEM 2018 from aboveLast month, several of my Promega colleagues and I attended the 2018 iGEM Giant Jamboree in Boston, MA. This annual event is the culmination of the International Genetically Engineered Machines competition, in which 350+ teams of high school, undergraduate and graduate students use synthetic biology to solve a problem they see in the world.

The iGEM Giant Jamboree is the closest I have ever come to a scientific utopia. For four days, several thousand students from 45 countries come together to share their experiences and discuss ways that science can change the world. They present impressive projects with real-world applications including human diagnostics and alternative energy. Collaboration and open science are among the core tenets of iGEM, and it’s not unusual to see three or more countries represented on the Collaborators slide at the end of a presentation. Each project also contains a public engagement component, which many teams fulfill with educational programs or partnerships with underrepresented communities.

Hey, iGEMers! We’re talking to you!

Posted on by Jordan Villanueva

The 2018 iGEM Giant Jamboree is upon us! This Wednesday, October 24th, thousands of you will flood into Boston, weighed down by posters and presentation materials, but energized by the excitement of a non-stop science-packed conference. Promega will also be attending, with a booth full of helpful giveaways and staff standing by to answer all your questions about science, Promega or future careers. As you make your final plans for the Jamboree, here are a few helpful tips for making the most of this incredible opportunity.

Catalyzing Solutions with Synthetic Biology

Posted on by Michele Arduengo, PhD

Computer-generated model of a virus.

The keynote speaker for this year’s International Symposium on Human Identification (ISHI), Andrew Hessle, describes himself as a catalyst for big projects and ideas (1). In biology, catalysts are enzymes that alter the microenvironment and lower the energy of activation so that a chemical reaction that would proceed anyway happens at a much faster rate—making a reaction actually useful to the biological system in which it occurs.

In practical terms, Andrew Hessel is the person who helps us over our inertia. Instead of waiting for someone else, he sees a problem, gathers an interested group of people with diverse skills and perspectives, creates a microenvironment for these people to interact, and runs with them straight toward the problem. Boom. Reaction started.

One of the problems he has set his mind toward is that of cancer drug development. Continue reading “Catalyzing Solutions with Synthetic Biology”

iGEM: Saving the World with Science

Every year, groups of teenagers gather together and brainstorm ways to save the world—with science. The International Genetically Engineered Machine (iGEM) Foundation is a non-profit organization that is dedicated to educating young scientists and enhancing open community and collaboration in the field of synthetic biology. They hold a competition every year with hundreds of teams participating from around the world.

Last year, Promega provided cloning reagents to the University of Chicago iGEM team, and they received a bronze medal for their work. We asked two of the team members, Steve Dvorkin and Julia Byeon, about their experience. Steve is a junior and majors in biology; he is co-president of the team this year. Julia recently graduated and works in public policy. Continue reading “iGEM: Saving the World with Science”

Designer Bacteria Detect Cancer

Posted on by Isobel Maciver

Every day scientists apply creative ideas to solve real-world problems. Every so often a paper comes up that highlights the creativity and elegance of this process in a powerful way. The paper “Programmable probiotics for detection of cancer in urine”, published May 27 in Science Translational Medicine, provides one great example of the application of scientific creativity to develop potential new ways for early detection of cancer.

The paper describes use of an engineered strain of E.coli to detect liver tumors in mice. The authors (Danino et al) developed a potential diagnostic assay that uses a simple oral delivery method and provides a readout from urine, all of which is made possible by some seriously complex and elegant science.
