Welcome back to the third and final part of our Women in Science series, where we’ve been exploring the key factors that perpetuate the gender gap in STEM. In Part 1 of this series, Breaking the Bias: Addressing the STEM Gender Gap, we dug into the key factors of gender stereotypes and male-dominated culture. Part 2, This is What a Scientist Looks Like: The Importance of Female Role Models in STEM, was all about the issue of fewer visible female role models in STEM. Last but certainly not least, this installment will focus on tackling the issue of the confidence gap, including the factors that play into it and the myriad ways we see it unfolds.
Part of my exploration of this topic included having conversations with a handful of my incredible female colleagues at Promega about the challenges women in STEM face. These colleagues were (in no particular order): Becky Godat, Instrumentation Scientist; Jacqui Mendez-Johnson, Quality Assurance Scientist; Johanna Lee, Content Lead, Marketing Services; Jen Romanin, Sr. Director, IVD Operations and Global Support Services; Kris Pearson, Director, Manufacturing & Custom Operations; Leta Steffen, Supervisor, Scientific Applications; Monica Yue, Technical Services Scientist; and Poonam Jassal, Manager, Regional Sales.
Welcome back to Part 2 of our March Women in Science series! In Part 1 of this series, Breaking the Bias: Addressing the STEM Gender Gap, we took a closer look at gender stereotypes and male-dominated culture and their roles as key factors in perpetuating the gender gap in STEM. In this installment, we will be continuing the conversation about the STEM gender gap and focusing on the key issue of fewer female role models in STEM.

What Does A Scientist Look Like?
If someone asked you to draw a scientist, what would that person look like? Over the past 5 decades, this question has been asked of over 20,000 students across all grades from kindergarten through 12th, and evaluated in nearly 80 studies. A meta-analysis of these decades of studies revealed some interesting findings.
Between 1966 and 1977, of the 5,000 drawings collected from students during the original 11-year study, only 28 of those 5,000 drawings (less than 1% of the drawings) depicted a female scientist, with all 28 of them being drawn by girls.
Within the broader March-long observance of Women’s History Month, March 8th marks the annual International Women’s Day. It’s a day of both celebration and reflection, dedicated not only to honoring the accomplishments and contributions that women bring to the table, but also to critical analysis of the areas where gender inequality still persists.
Although we’ve made big strides in the last few decades, women are still significantly under-represented in many fields of science, technology, engineering and mathematics (STEM). Women make up nearly 50% of the US workforce, but less than 30% of that number are STEM workers, and with women comprising less than 30% of the world’s researchers.
In honor of this year’s theme for International Women’s Day, Break the Bias, and as a woman in science myself, I was interested in exploring the challenges of anyone who identifies and lives as a woman in science, and the key factors that continue to perpetuate the gender gap in STEM fields. I invited eight of my female colleagues at Promega—diverse in roles, age, educational background, ethnicity, and experience—to sit down with me (virtually) to learn more about them and their experiences as women in STEM.
While you can rely on Taylor Swift and Adele to help heal emotional heartbreak, unfortunately treating a physically “broken” heart, a heart damaged by fibrosis, is a much more complicated process than putting on your favorite sad songs and wallowing in your feelings. In a recent study published in Science, researchers developed a therapeutic approach to treat damaged hearts in mice through the removal of scar tissue using genetically engineered immune cells (CAR T cells) and the mRNA technology used in the mRNA coronavirus vaccines.
For decades now, peptides have been a molecule of interest for drug discovery research. Peptides offer a unique opportunity for therapeutic intervention that closely mimics natural pathways, as many physiological functions utilize peptides as intrinsic signaling molecules. Macrocyclic peptides, in particular, have recently proven to be promising candidates for targeting intracellular protein–protein interactions (PPIs), an attractive but hard-to-reach therapeutic target for conventional small molecule and biological drugs.
As with any opportunity, there are also challenges that accompany the peptide therapeutic development. Peptide ligands typically have poor membrane permeability, so thus far the majority of peptide therapeutics predominantly target extracellular proteins and receptors. There are also multiple mechanisms for cellular uptake of peptides, including both energy-dependent routes like endocytosis, and energy-independent, like passive diffusion or membrane translocation. Multiple mechanisms of cellular uptake paired with poor permeability makes engineering enough membrane permeability into peptides in order to advance them through drug discovery pipelines extremely difficult.
There are other factors to consider in developing peptide therapeutics, such as solubility, protein/lipid binding and stability, which can also have an affect on the overall cytosolic concentration and, ultimately impact the ability of the peptide to effectively engage its desired intracellular targets.
With so many challenging factors, the ability to have a predictive, high-throughput assay to assess cell permeability, independent of the mechanism(s) of entry, would be a critical and invaluable tool to support peptide drug discovery research.
Each year, the International Forum on Consciousness draws thought leaders from around the world to explore important, and often challenging, topics related to the exploration of consciousness. The theme for this year, Consciousness of Connection: Awakening from Despair to Awe, is an invitation to broaden curiosity about connection and take a closer look at the variety of connections that we forge in our lives.
Participants will examine the kinds of connections that transcend our individual selves and reach our inner desire to be part of an interconnected world, perhaps to transform our current sense of the individual, community, and society, from independent to interdependent. More specifically, the Forum will examine connection across the primary aspects of our lives with:
Self, and the many selves in our amazing neural networks
Others, and the multiple communities we intersect
Nature, and the breadth of life forms that surround us
Although it is easy to get swept up in the dark year that was 2020, one advantage of overwhelming darkness is it makes it easier to find the bright spots, the beacons of hope, the people working to make the world a better place. One of these bright spots was the launch of Wild Genomes, a new biobanking and genome sequencing program through Revive & Restore.
Back in 2018, the Catalyst Science Fund was established by Revive & Restore with a 3-year pledge from Promega for $1 million annually. The purpose of the fund is to help support proof-of-concept projects and to advance the development of new biotechnology tools to address some of the most challenging and urgent problems in conservation that currently lack viable solutions, including genetic bottlenecks, invasive species, climate change and wildlife diseases.
Through this fund, the Wild Genomes program was launched, with the goal of getting sequencing and biobanking tools into the hands of people working to protect biodiversity right now, and to help support them in applying genomic technologies towards their wildlife conservation efforts.
In their first request for proposals , the competitive Wild Genomes program received over 58 applications from researchers in 19 different countries, all of which aimed to address various species conservation issues using applied genomic technologies. The second round of projects, to be announced this Spring, will focus solely on marine species. Take a look at these first 11 amazing projects that have been awarded funding and the species conservation challenges they are taking on below:
Canine distemper virus (CDV) is a highly contagious pathogen that is the etiological agent responsible for canine distemper (CD), a systemic disease that affects a broad spectrum of both domestic dogs and wild carnivores. While there are commercially available vaccines for CDV that can provide immunity in vivo and protect canines from contracting CD, there is a strong demand for effective canine distemper antivirals to combat outbreaks. Such drugs remain unavailable to date, largely due to the laborious, time-consuming nature of methods traditionally used for high-throughput drug screening of anti-CDV drugs in vitro. In a recent study published in Frontiers in Veterinary Science, researchers demonstrated a new tool for rapid, high-throughput screening of anti-CDV drugs: a NanoLuc® luciferase-tagged CDV.
On August 6, 2020, the first successfully cloned Przewalski’s horse was born at the Texas-based veterinary facility, Timber Creek Veterinary, along with a new hope for restoring some much-needed genetic diversity to the species. The successful birth of this foal is the culmination of the collaborative efforts between Revive & Restore, San Diego Zoo Global (SDZG), and ViaGen Equine, and lays the groundwork as an important model for future conservation efforts.
The new Przewalski’s foal (pronounced “shuh-VAL-skees”) has been affectionately dubbed Kurt, in honor of noted animal conservationist, geneticist and pathologist, Dr. Kurt Benirschke. Dr. Benirschke played an instrumental role in founding the Frozen Zoo®, a genetic library comprised of cryopreserved cell lines of endangered species. Established in the 1970s, this collection was built on a foundation of prescient hope, banking on the future development of reproductive and cloning technologies that did not yet exist.
Now thanks to his foresight, that gamble is paying off and the fruits of that labor are literally being brought to life almost 50 years later through Kurt the foal, who is as adorable as he is important to the future of his kind.
As the SARS‐CoV‐2 pandemic continues to rage across the United States and around the globe, the demand for COVID‐19 testing is increasing. The vast majority of the COVID-19 assays use RT‐qPCR to detect the viral RNA in patient samples such as nasopharyngeal swabs, which are collected and stored in viral or universal transport media (VTM/UTM). The general workflow for these COVID‐19 assays can be broken down as follows:
Collect and store patient samples
Ship samples to testing laboratory
Extract RNA from samples
Amplify and analyze samples
While many companies who manufacture the products that are used in these steps have been able to adapt and significantly increase their production capacities, there are still gaps between the supply of these products and the global test demand. Both the sample collection and storage step and the RNA extraction/purification step have a tendency to bottleneck and experience supply constraints. One way to address these bottlenecks and expand production capacity for these in‐demand products is to evaluate the viability of skipping a step in the workflow, without hindering the ability to detect viral RNA from samples.
