Ebola virus (EBOV) and Marburg virus (MARV) are two closely-related viruses in the family Filoviridae. Filoviruses are often pathogenic, causing hemorrhagic fever disease in human hosts. The Ebola outbreak of 2014 caught the world by surprise by spreading so quickly and severely that public health organizations were unprepared. The devastating outcome was a total of over 11,000 deaths by the time the outbreak ended in 2016. Research that provides further understanding of filoviruses and their potential for transmission is important in preventing future outbreaks from occurring. But what if the outbreak comes from a virus we’ve never seen before?
All in the viral family
A recent study published in the journal Nature Microbiology provides evidence of a newly identified filovirus species. Using serum samples taken from bats, a well-known host for filoviruses, Yang et al. isolated and identified viral RNA for an unclassified viral genome sequence using next generation sequencing analysis. This new virus genome sequence was organized with the same open reading frames as other filoviruses, encoding for nucleoprotein (NP), viral protein 35 (VP35), VP40, glycoprotein (GP), VP30, VP24, and RNA-dependent RNA polymerase (L). This new genome sequence shared up to 54% of the nucleotide sequences for the filovirus species Lloviu virus (LLOV), EBOV and MARV, with MARV being the most similar. Their analysis suggested that this novel virus should be classified within the Filoviridae family tree as a separate genus, Dianlovirus, and was named Měnglà virus (MLAV).
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.
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.

If you follow Promega on social media, you may have noticed that several scientists and science communicators (including myself) were sharing posts for Science-A-Thon this week. The event was organized by the Earth Science Women’s Network (ESWN), whose mission is to create opportunities for mentorship, community, and collaboration for women in science.
The goal of Science-A-Thon was to “increase visibility of scientists and the important work they do to the public.“ The week-long celebration of science also served as a campaign to raise money for ESWN and to support Science Forward, “a STEM-wide initiative that empowers scientists, promotes scientists as role models, and builds on-ramps for students to engage in STEM.” Scientists and science communicators were invited to share their #dayofscience on Twitter, Instagram, and/or Facebook to give followers a better idea of what a scientist actually does from day to day—from morning coffee to meetings to micropipettes. Science-A-Thon followed a science outreach trend similar to the #scientistswhoselfie movement by humanizing science and showcasing the fact that scientists are people, too, with diverse backgrounds and interests.

When someone is admitted to a hospital for an illness, the hope is that medical care and treatment will help them them feel better. However, nosocomial infections—infections acquired in a health-care setting—are becoming more prevalent and are associated with an increased mortality rate worldwide. This is largely due to the misuse of antibiotics, allowing some bacteria to become resistant. Furthermore, when an antibiotic wipes out the “good” bacteria that comprise the human microbiome, it leaves a patient vulnerable to opportunistic infections that take advantage of disruptions to the gut microbiota.
One such bacteria, Clostridium difficile, is of growing concern world-wide since it is resistant to many different antibiotics. When a patient is treated with an antibiotic, C. difficile can thrive in the intestinal tract without other bacteria populating the gut. C. difficile infection is the leading cause of antibiotic-associated diarrhea. While symptoms can be mild, aggressive infection can lead to pseudomembranous colitis—a severe inflammation of the colon which can be life-threatening.
Earlier this year, an opinion piece published in Science criticized scientists who use Instagram as a tool for science outreach.1 The author argued that “time spent on Instagram is time away from research” and specifically called out female scientists for snapping selfies instead of proposing policy changes to battle the systemic issues of marginalization in STEM fields.
The piece received a significant amount of backlash from a community of social media-savvy scientists. The community commonly referred to as “Science Twitter” is active in using the social media platform as a novel way to humanize science and engage with science-curious followers. Likewise, Instagram provides snapshots into the diverse lives of scientists who feel free to offer their own personal perspectives rather than acting as a representative of their institutions. These growing communities also challenge the stereotypical image of scientists as white men wearing lab coats. Furthermore, the digital presence of scientists and science communicators continues to be fueled by trending hashtags like #actuallivingscientist, #stillascientist, and #scientistswhoselfie.
