Water plays a vital role in countless aspects of daily life—drinking, cooling, recreation and more. However, the same systems that deliver these benefits can also harbor Legionella, a waterborne bacteria responsible for Legionnaires’ disease, a severe form of pneumonia (1). Legionella thrives in stagnant aquatic environments, many of which are human-made and common in modern infrastructure, like in cooling towers, hot tubs and complex building water systems. In this blog, we explore the risks posed by Legionella, the limitations of traditional detection methods and how advanced tools at Promega are transforming water safety monitoring.
Cyanobacteria, microscopic photosynthetic bacteria, have been quietly shaping our planet for billions of years. Responsible for producing the oxygen we breathe, these tiny organisms play a critical role in the global carbon cycle and are now stepping into the spotlight for another reason: their potential to both understand and potentially combat climate change.

Recently, researchers discovered two new strains of cyanobacteria, UTEX 3221 and UTEX 3222, thriving in a marine volcanic seep off the coast of Italy. While cyanobacteria are virtually everywhere there is water and light—from calm freshwater ponds to extreme environments like Yellowstone’s hot springs—this particular habitat is remarkable for its naturally high CO₂ levels and acidic conditions. For these newly identified strains, a geochemical setting like marine volcanic seeps have likely driven the evolution of unique traits that could make them valuable for carbon sequestration and industrial applications.
There’s something oddly captivating about watching a film that makes you jump, scream, or better yet—a film that sticks with you long after watching. Millions of people embrace the fear, willingly diving into the dark world of horror movies. But why? What is the appeal of subjecting ourselves to terror? The reasons we watch and enjoy scary movies go far beyond the jump scares—they’re deeply psychological.
For those who find themselves covering their eyes or clutching the nearest pillow, it might be hard to understand. Yet, as the hair-raising month of October ends, many people spent the 31 days leading up to Halloween watching films designed to scare the daylights out of them. In this blog, we explore why people enjoy fear (or why they don’t) and what psychology reveals about the movies that truly terrify us.
In June, Promega proudly announced the ten winners of the 2024 Promega iGEM Grant. These extraordinary teams have been hard at work preparing for the iGEM Grand Jamboree, which will take place from October 23-26, 2024, in Paris, France. We interviewed a handful of this year’s grant recipients to learn more about their projects and journeys they’ve taken to reach this exciting milestone. Below are stories from four of the winning teams.
At the end of July, many people across the globe were preparing to tune into the two-week, 2024 Olympic Games in Paris, France. The Olympics were slated to feature several high-profile athletes—including Simone Biles (USA, artistic gymnastics), Eluid Kipchoge (Kenya, marathon) and Marta Vieira da Silva (Brazil, football). However, in the lead-up to the Games, the International Olympic Committee (IOC) focused on a secondary player: Artificial Intelligence (AI). The IOC laid out an ambitious AI agenda aimed to enhance athlete performance, ensure fairness and optimize operations. The 2024 Paris Olympics represent a significant leap forward in integrating AI into the world of sports.
“Together, we can unlock AI’s full potential to promote solidarity, further digitalization, improve sustainability and resilience, and reinforce the role of sport in society.” – Olympic AI Agenda
Here, we explore several applications of AI in the 2024 Paris Olympics.
Contraception, or birth control, is an important tool in family planning. Given the fourfold increase in population over the last century1 there is a clear need for more affordable, reversible, and safe methods of contraception. At present, the responsibility of takingcontraceptives falls largely on people with female reproductive organs as there is no current method of birth control for people with male reproductive organs. The search for a non-hormonal, male birth control has been an elusive goal in the field of reproductive health.
Recently, a group of scientists from Baylor College of Medicine with contributions from Promega scientists identified a novel compound that 1) inhibits a specific kinase and 2) functions as a reversible male contraceptive. The kinase targeted in this study is the serine/threonine kinase 33 (STK33); a genetic knockout of this gene in male mice is known to cause sterility. The team published their work in Science and utilized a suite of approaches—including DNA-Encoded Libraries (DELs), crystallography, and cellular NanoBRET™ Target Engagement Kinase Assays—to discover a potent inhibitor of STK33 (CDD-2807). The CDD-2807 inhibitor has shown promising results in inducing reversible contraception in male mice, marking a significant milestone in the development of non-hormonal contraceptive options. Let’s dive into the foundation, novel methodology, collaboration, and implications for this work.
In April 2024, Promega hosted the “Target Engagement in Chemical Biology Symposium” at the Kornberg Center, a research and development hub on Promega’s campus in Madison, Wisconsin. The goal of the symposium was to gather interdisciplinary researchers interested in the field of small molecule target engagement to foster collaboration through knowledge sharing and innovation. The symposium featured a 1.5-day agenda packed with 23 speakers, 4 workshops, poster sessions and social events. Over 130 attendees gathered to participate in the multifaceted event, with participants from different geographic regions and in different research sectors from academia to government to industry.

The symposium highlighted the collective commitment to overcoming the challenges in drug discovery by developing more targeted and efficacious treatments, driven by a shared determination to create innovative solutions that address unmet medical needs. While we cannot share all the exciting research presented at the symposium, we are thrilled to highlight a few talks that exemplify the novel work and collaborative spirit of this research community.
Farmers everywhere strive to protect their crops and ensure a stable food supply while minimizing environmental harm. A promising approach to achieving this leverages a plant’s built-in defense mechanisms, reducing the need for chemical interventions. Many geneticists and agronomists lean on technologies that can automate and streamline nucleic acid extraction and pathogen detection to identify naturally pest resistant crops and, ultimately, keep up with the changing agricultural landscape.
In an era where science moves at a rapid pace, integrating automation into your lab is not just beneficial but essential. When you automate your lab, you free up an invaluable resource: time. From scaling up operations and handling increased demand to improving consistency and reducing manual errors, automation can be the key to achieving higher throughput, saving costs, and—most importantly—enabling researchers to focus on the science rather than the process. However, embarking on a lab automation project requires careful planning, clear goals and an understanding of the intricacies involved in automating complex biological workflows.
In the evolving field of forensic science, a study by Fantinato et al. has opened new avenues in using DNA extraction and analysis to recover important information from crime scenes. Their work, “The Invisible Witness: Air and Dust as DNA Evidence of Human Occupancy in Indoor Premises,” focuses on extracting DNA from air and dust. This novel approach could revolutionize how crime scenes are investigated, especially in scenarios where traditional evidence—like fingerprints or bodily fluids—is scarce, degraded or has been removed from surfaces.
