Taking the Plunge: How the Seine Became Olympic-Ready

What would the Olympics be without a little controversy? From spy drones to air conditioning battles and debates over the bronze medal in women’s floor exercises, the 2024 Games had their fair share. Yet, amidst all the drama, one story stood out—the transformation of the Seine River. After being off-limits to swimmers since 1923, the Seine made a historic comeback this summer, hosting Olympic swimming events for the first time in modern history, including a 10K marathon, the aquatic portion of the triathlon and a Paralympic swimming event (4). With nearly 1 billion people watching, the Seine needed to be more than just swimmable – it had to be media-ready, as even a small misstep could have tarnished the river’s new image.

Understanding Persistent Digestive Disorders With Multiplex PCR

Digestive disorders are a leading cause of mortality worldwide, with diarrhea being particularly deadly. Despite declining mortality rates, diarrhea still causes an estimated 1.65 million deaths annually, with the highest burden in low- and middle-income countries, largely due to poor sanitation and lack of clean water. While acute diarrhea has been extensively studied, less is known about the pathogens responsible for long-lasting digestive issues, including diarrhea and abdominal pain that persist for 14 days or more. A recent study in Scientific Reports offers valuable insights into the prevalence of these pathogens and highlights the importance of advanced molecular diagnostics in addressing this issue.

How Artificial Intelligence Revolutionized the 2024 Paris Olympics

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.

Ancient Retroviruses and Modern Cancer: Role of Endogenous Retroviruses in Transcriptional Changes in Tumor Cells 

Approximately 30 million years ago, a retrovirus integrated into the germline of a common ancestor of baboons, gorillas, chimpanzees and humans. That endogenous retrovirus, now known as gammaretrovirus human endogenous retrovirus 1 (HERV-1), may provide clues about the aberrant regulation of gene transcription that enables tumor cells to grow and survive.  

Understanding the Mechanism Behind Cancer Gene Expression 

Scientists have long described the striking differences in gene expression, signaling activity and metabolism between cancer cells and normal cells, but the underlying mechanisms that cause these differences are not fully understood. In a recent Science Advances article, published by Ivancevic et al., researchers from the University of Colorado, Boulder; the University of Colorado Anschutz Medical Campus, and the University of Colorado School of Medicine report their efforts to identify endogenous retrovirus elements that might be part of the answer to the complex question of what biological events are responsible for the changes in gene expression in cancer cells.  

The researchers hypothesized that transposable elements (TEs), specifically those associated with endogenous retroviruses could be involved in cancer-specific gene regulation.  Endogenous retroviruses (ERVs) are the remnants of ancient retroviral infections that have integrated into the germline of the host. 

The transposable element LTR10, derived from an endogenous retrovirus, can alter gene expression in a number of cancers. Artist's conception of an invasive cancer cell.

How Promega Supports Sustainable Science

What is ACT and why does it matter?

The ACT label stands for Accountability, Consistency and Transparency. The ACT label provides information on the environmental impact of life science products to help researchers make informed choices about the products they use in their labs. ACT was developed by the non-profit organization My Green Lab, in collaboration with the International Institute for Sustainable Laboratories (I2SL).

The ACT label is one of the most comprehensive product labels for the life sciences. It measures the environmental impact of a product across four categories: manufacturing, user impact, end of life, and innovation. The criterion was developed with input from industry leaders, scientists, manufacturers, and sustainability directors. Most categories are scored on a scale from 1 to 10; 10 being the highest score. Other values are assigned a yes/no value or in some instances, a specific value per day (ex. kWh/day). The Environmental Impact Factor (EIF) is the summation of these categories. The varying energy usage and distinct reports across global markets has resulted in separate awards for different world regions. By choosing products with the ACT label, researchers can align their purchasing behaviors with any goals of reducing their environmental footprint and support sustainable practices in the life science industry.

The Casual Catalyst: Science Conversations and Cafes

There is no shortage of stories about great scientific collaborations that have taken root as the result of an excited conversation between two scientists over sandwiches and beer at a bar or a deli. One of the most famous examples of such a conversation was that between Herbert Boyer and Stanley Cohen when they attended a conference on bacterial plasmids in 1972—that very conversation led to the formation of the biotechnology field as the two scientists worked together to clone specific regions of DNA (1).  

“Over hot pastrami and corned beef sandwiches, Herbert Boyer and Stanley Cohen opened the door to genetic engineering and laid the foundations for gene therapy and the biotechnology industry.”  

Steven Johnson, author of Where Do Good Ideas Come From, credits the English coffee house as being crucial to the spread of the enlightenment movement in the 17th and 18th centuries (2). He argues that coffee houses provide a space where ideas can come together and form networks. In fact, he defines the concept of “idea” not as a single entity—a grand thought that poofs into existence upon hard work—but at its simplest level, a new idea is a new network of neurons firing in sync with each other.  

Johnson further argues that the development of great new ideas not only requires a space for ideas to bump into each other, connect and form a network, but also that great ideas are rarely the product of a single “Eureka” moment. Rather, they are slowly developing, churning hunches that have very long incubation periods (2).

Elephants May Call Each Other By Name

Elephants intertwining trunks
New research points to the possible use of names among elephants in the African savanna

Names are part of something called “arbitrary communication”, wherein a sound represents an idea without imitating it. Where we have so far seen names used in nature, they are typically imitative—for instance, bottlenose dolphins and parrots mimic an individual’s signature call to get their attention. However, this differs from how humans refer to each other using an arbitrary or random sound chosen to represent an individual. The use of arbitrary language is a mark of linguistic complexity that moves beyond the limitations of imitative speech and expands expressive power into the potential exchange of intricate ideas, abstract concepts and symbolic thought.
