We share this planet with approximately 8.7 million species of plants and animals. Within such a diverse environment, it’s only natural that many complex relationships have developed among different species. Some relationships are mutually beneficial, some are parasitic—and some are lethal.
Natural toxins and venoms are biologically active compounds produced by normal metabolic processes in an organism but are harmful to other organisms. Typically, toxins are encountered passively or ingested by the affected organisms, and have a specific mode of action and binding site within a cell. In contrast, venoms are introduced directly into the victim through a specialized delivery mechanism, and they may consist of a mixture of compounds that affect a range of cell types and tissues (1). Both types of poisons are produced for predation, defense, or to offer a competitive advantage (1).
The elk tooth is small and ancient, with a crude hole bored through the top. It was likely worn as a pendant, but worn by whom? Was the owner male or female? Where did they come from? Did the pendant indicate their social status, mark a significant accomplishment, was it a gift, or was it worn as an expression of individuality?
Artifacts such as personal ornaments and tools play a pivotal role in helping us understand the migration, behavior and cultures of ancient peoples. To date, this information has stopped short of providing insight into things like the biological sex or genetic ancestry of the individuals who may have worn or used these items, and thus limited our ability to accurately characterize societal roles and behaviors. Recent advances in DNA techniques and technologies, and one little pendant, might be changing that.
Foodborne disease affects almost 1 in 10 people around the world annually, and continuously presents a serious public health issue (9).
Food Contamination is common and can be seen in a variety of forms and food products.
More than 200 diseases have evolved from consuming food contaminated by bacteria, viruses, parasites, and chemical substances, resulting in extensive increases in global disease and mortality rates (9). With this, foodborne pathogens cause a major strain on health-care systems; as these diseases induce a variety of different illnesses characterized by a multitude of symptoms including gastrointestinal, neurological, gynecological, and immunological (9,2).
But why is food contamination increasing?
New challenges, in addition to established food contamination hazards, only serve to compound and increase food contamination risks. Food is vulnerable to contamination at any point between farm and table—during production, processing, delivery, or preparation. Here are a few possible causes of contamination at each point in the chain (2):
Production: Infected animal biproducts, acquired toxins from predation and consumption of other sick animals, or pollutants of water, soil, and/or air.
Processing: Contaminated water for cleaning or ice. Germs on animals or on the production line.
Delivery: Bacterial growth due to uncontrolled temperatures or unclean mode of transport.
Preparation: Raw food contamination, cross-contamination, unclean work environments, or sick people near food.
Further emerging challenges include, more complex food movement, a consequence of changes in production and supply of imported food and international trade. This generates more contamination opportunities and transports infected products to other countries and consumers. Conjointly, changes in consumer preferences, and emerging bacteria, toxins, and antimicrobial resistance evolve, and are constantly changing the game for food contamination (1,9).
Hence, versatile tests that can identify foodborne illnesses in a rapid, versatile, and reliable way, are top priority.
Chris Geo Provido, Divya Kashyap and Deborah Ola listen to presentations at D.O.O.R.S. Scholars Day
When six undergraduate students from across the country convened at Promega Madison to present their research, several of them were surprised to see Promega CEO Bill Linton in the audience.”
“I’ve never interacted with a biotechnology company like this, and then the CEO shows up,” says Valeria Sanchez Estrada. “We actually discussed ChatGPT and how AI and machine learning can advance biology research.”
Valeria, a second-year student from St. John’s University, was a 2022 recipient of the Diversification Of Our Research Scientists (D.O.O.R.S.) Scholarship, provided the BioPharmaceutical Technology Center Institute and Promega North America. The scholarship provides ten students with a $5,000 award that can be used towards educational fees, books and supplies to support their scientific education. The scholarship is open to undergraduate students from underrepresented backgrounds pursuing a biotechnology-related major.
Several D.O.O.R.S. Scholars eat lunch with Promega scientists
On March 24, 2023, scholarship recipients were invited to Promega Madison for the first in-person D.O.O.R.S. Scholars Day. In addition to presenting their research, students had the opportunity to meet with Promega R&D scientists and tour the beautiful Kornberg Center. Overall, the event was a day of celebration and building connections between outstanding students and the biotechnology industry.
“I imagined industry just being about hard science and lab time,” says Chris Provido, a third-year student from Bowie State University. “But Promega’s values showed me today that although we’re all scientists, your humanity is just as important, and it’s important to find a balance between hard science and being human.”
The Earth Month Plant Swap included cuttings from displays throughout the Promega Madison campus
Earth Day 2023 is past, but protecting our environment and natural resources is important every day of the year.
As a company, Promega has set ambitious goals for reducing our carbon emissions, plastic waste and water usage by 2030. We design each new building to surpass the sustainability features of all previous facilities. Our culinary garden employs techniques that are beneficial to the ecosystem, from enriching the soil to supporting local wildlife. In fact, over 225 acres of our 400-acre Madison campus is dedicated to preserved prairie, wetlands and woodlands.
Promega employees are also dedicated to reducing their impact on the natural world. This month, a series of employee-hosted Earth Month events gave Madison-based Promega employees the opportunity to test-drive electric cars, trade plants and learn about sustainable lawncare. Here are a few highlights from Earth Month 2023 at Promega.
Cells, commonly considered the smallest unit of life, provide structure and function for all living things (3).

Because cells contain the fundamental molecules of life, in some situations such as yeast, a single cell can be considered the complete organism. In other situations, for more complex multicellular organisms, a multitude of cells can mature and acquire different, specialized functions (3).
Cells developing specificity are undergoing differentiation, a process where a cell’s genes are either turned “on” or “off” resultant in a more specific cell type. As these differentiated cells start to exhibit their identity, they organize themselves into the tissues, organs, and organ systems integral to the functioning of a multicellular, developing organism. This process in which order and form is created within a developing organism is referred to as morphogenesis (5).
“I just feel burned out.” I heard those words recently from my college junior. For him, the spring semester is barreling to a close and he is feeling tired, unmotivated and unproductive. He isn’t alone; most of us have said (or thought) those words at some point in our lives. We use the words when we are feeling tired, stressed or overwhelmed at work (or school), but burnout is more than just an emotional response to workload or other job-related challenges. Burnout can quickly cascade into more physical symptoms and take a toll on both our personal and professional lives.
Bioluminescence imaging is a powerful tool for non-invasive studies of the effect of treatments on cells and tissues. The luminescent signal is strong, and can be used in vivo, enabling repeated observations over time, allowing longitudinal study of cellular changes for hours or days. Bioluminescence imaging can be used in live animals over varying periods of time, without interfering with normal cellular processes.
Fluorescence imaging is also used in cellular studies. Although it can provide a stronger signal than luminescence, fluorescence requires light for excitation, and thus its in vivo use is limited at a tissue or cell depth greater than 1mm.

In addition, autofluorescence can be an issue with fluorescence imaging, as cellular components and surrounding proteins and cells can fluoresce when exposed to light. Autofluorescence can result in high background signals, making it difficult to distinguish true fluorescence from background.
International Pet Day, observed each year on April 11th, provides the purrfect opportunity to reciprocate all the labored love and affection our pets so freely give us. There’s no doubt that our furry, feathered, and scaley friends greatly improve our quality of life. But did you know there are benefits to this human-animal bond beyond their incredible cuteness? Read about some of the paw-some science-approved benefits that can come with pet ownership.
The Biotechnology Youth Apprenticeship Program hosted by the BTC Institute gives high school students an opportunity to gain hands-on experience in a research lab. Students can work as paid apprentices for either one or two years while also attending weekly training sessions at the BioPharmaceutical Technology Center. Through this program, students can graduate high school with robust knowledge of lab safety and fundamental techniques, as well as a strong understanding of the soft skills required to succeed in science, from reading peer-reviewed literature to delivering a research presentation.
Many of these students will grow up to pursue careers in science, from academic research labs to the biotechnology industry. Some of them have returned to Fitchburg to work at Promega, the primary corporate sponsor of BTC Institute. As these scientists progress in their careers, the skills they developed in the Youth Apprenticeship Program continue to support their work every day.
