In January 2024, Antonio Alcamí and Ángela Vázquez, virologists from the Severo Ochoa Centre for Molecular Biology, landed in Antarctica to study the avian flu virus. They embarked on a journey to monitor 17,000 penguins as part of their efforts to study the virus and prevent its spread. Our Maxwell® RSC 48 was delivered to extract nucleic acids from the samples, which are set to be analyzed using qPCR.
In 2000 measles was officially declared eliminated in the United States (1), meaning there had been no disease transmission for over 12 months. Unfortunately it was not gone for good. So far in 2024 there have been 8 outbreaks and 131 cases. Ninety of these case (69%) are associated with an outbreak and seventy (53%) have resulted in hospitalization (as of May 2, 2024; 2).
Before the development of a vaccine in the 1960s, measles was practically a childhood rite of passage. This common childhood disease is not without teeth however. One out of every 20 children with measles develops pneumonia, 1 out of every 1,000 develops encephalitis (swelling of the brain), and 1 to 3 of every 1,000 dies from respiratory and neurological complications (3). Between the years of 1958 and 1962, the US averaged 503,282 reported cases of measles (4). The first measles vaccine was licensed in the U.S. by John Enders in 1963, and not surprisingly, after the measles vaccine became widely used, the number of cases of measles plummeted. By 1970, there were under 1,000 cases (2).
What was surprising was that with the disappearance of this childhood disease, the number of childhood deaths from all infectious diseases dropped dramatically. As vaccination programs were instituted in England and parts of Europe, the same phenomenon was observed. Reduction or elimination of measles-related illness and death alone can’t explain the size of the decrease in childhood mortality. Although measles infection is associated with suppression of the immune system that will make the host vulnerable to other infections, these side effects were assumed to be short lived. In reality, the drop in mortality from infectious diseases following vaccination for measles lasted for years, not months (5).

At Promega, the arrival of spring is not merely a celebration of nature’s rejuvenation, but also a reflection of our steadfast commitment to environmental stewardship. This vibrant season allows us to spotlight a crucial ecological initiative: the controlled prairie burn. Conducted every three to five years across over 25 acres of native prairie restorations, these burns are essential for habitat health. They not only reduce the risk of wildfires but also curb invasive weeds and stimulate new growth. Undertaking these burns exemplifies how Promega reinforces its commitment to environmental stewardship – a foundational principle that guides our operations and influences our architectural designs.

April 2024 marked the 23rd anniversary of Sexual Assault Awareness Month (SAAM) in the United States. While we have crossed into May, the importance of what SAAM stands for does not diminish with the changing of the calendar. The National Sexual Violence Resource Center (NSVRC) emphasizes that SAAM is a time to not only draw attention to the prevalence of sexual assault, but to also educate individuals and communities about how to prevent sexual violence.

A tightly coiled lattice unspools to reveal a sinuous DNA stand. Along its length, tendrils of RNA sprout, growing bit by genetic bit. Eventually, the signal to stop and break away arrives, yielding a new strand of RNA that faithfully transcribes the DNA strand’s genetic code. Proteins trim and splice this new growth, pruning it so it takes its final form, messenger RNA. More proteins then ferry this mRNA strand through a pore in the nuclear envelope into the open space of the cell’s cytoplasm. Ribosomes and codon-carrying tRNA alight onto the released mRNA strand, reading the instructions it has carried from the DNA in the nuclear nursery. From this trio new forms emerge, bulbous proteins shaped by their destined purpose.
And so it goes, every second of every day, in the tens of trillions of cells in your body…
…And on the tens of thousands of kit packages we deliver to customers across the globe every year.

This project is the first embodiment of the city of Madison’s pedestrian mall experiment, set to kick off in May. Taylor McAda, Promega Senior Graphic Designer, was selected to design and paint one of four original 20-foot circle murals.
For decades, pharmaceutical companies have relied on high-throughput screening (HTS) as the first step in the drug discovery process. After an initial screening of thousands of compounds, scientists select a smaller list of candidate drugs that is then used for further downstream testing. A major limitation to HTS, however, is the need to synthesize all compounds used in the screen—the compounds need to physically exist to be tested. This significantly limits the number of compounds that can be tested, hindering the discovery of new drugs.
What if we could test compounds even before they are synthesized?

In the Spring of 2015, greenhouse tomato plants grown in Jordan presented with a mosaic pattern of light and dark green patches on leaves, narrowing leaves, and yellow- and brown-spotted fruit (Salem et al. 2015). The pathogen was identified as a novel plant virus, the tomato brown rugose fruit virus (ToBRFV), and the original outbreak was traced back to the fall of 2014 to Israel (Luria et al. 2017). This newly emerging virus can infect tomato and pepper plants at any stage of development and greatly affect crop yield and quality. Furthermore, the virus spreads rapidly by mechanical contact but can also be spread over long distances by contaminated seeds (Caruso et al. 2022), and as of 2022 it had been detected in 35 countries across four continents (Zhang et al. 2022). Compounding its transmissibility, is the ability of the virus escape plant genetic resistance to viral infection (Zhang et al. 2022). There are seven host plants for the virus, including some common grasses and weeds, which could act as a reservoir for the virus, even if it is eliminated from commercial crops. Some researchers consider ToBRFV to be the most serious threat to tomato production in the world.

The massive metal plates shift until a half-ton of compressed plastic tumbles out onto the waiting pallet. The crowd cheers. Permanent markers are passed around and everyone takes turns signing the massive block.
It’s February 16, 2024, and the members of the Promega Sustainability Committee are gathered to witness the first bale of plastic film being ejected from the Madison campus’s new baler. It’s only the first bale, but it represents a major step in the company’s efforts to reduce plastic waste.
“All of this would have gone to the landfill if we hadn’t set up this program,” Katelyn says. “It feels good to know that at least some of my waste is getting a second life.”
Plastic film is notoriously difficult to recycle and takes decades to break down in a landfill. The Promega initiative to divert this waste was started by a small group of employees who noticed a problem and worked for over a year to build a sustainable solution. What began as a small volunteer operation grew to spur capital investment in a process that will rescue around 35,000 pounds of plastic per year.

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.
