Alzheimer Disease and Metabolic Dysfunction: A Critical Intersection in Brain Health

Posted on by Simon Moe

This guest blog post is written by Alden Little, a Marketing Intern at Promega.

Alzheimer disease (AD) is one of the most devastating neurodegenerative disorders, affecting millions worldwide. While much attention has been given to amyloid plaques and tau tangles, emerging research suggests that metabolic dysfunction in the brain plays a crucial role in the disease’s progression. A recent study published in Acta Neuropathologica by Schröder et al. sheds new light on how astrocytes—the brain’s metabolic support cells—are affected in AD, and how their dysfunction impacts neurons.

Auguste Deter, a patient of Dr. Alzheimer, who first described the hallmark plaques and tangles of AD.

Ice Age Secrets: The Discovery of a Juvenile Sabretooth Cat Mummy 

Posted on by Shannon Sindermann

In the permafrost of Siberia, a remarkable discovery has been made—a mummified juvenile sabretooth cat, Homotherium latidens, frozen in time for over 35,000 years. This discovery, made along the Badyarikha River in the Indigirka River Basin of Yakutia, Russia, offers an exciting glimpse into a species that has no modern analog (a living equivalent of something extinct) (1). For paleontologists and evolutionary biologists, it provides an unprecedented look at an ancient predator that roamed the Earth during the Ice Age. So, how is this cub mummy truly fascinating scientists?

The permafrost of Siberia is a treasure trove of Ice Age fossils, but the discovery of a mummified Homotherium cub stands out for its rarity and significance. While bones can tell us a lot about the history of an extinct species, mummies—where the animal’s soft tissues, such as fur, skin and sometimes internal organs, are preserved—offer far more detailed information. ‘Mummies’ refer to animals (or humans) that have been preserved with their soft tissues intact, often through natural or intentional processes like drying or embalming. This preservation allows scientists to gain insights into the organism’s diet, health, development and adaptations—details that bones alone can’t reveal!

Thanksgiving Cooking: Lessons in Chemistry

Posted on by Shannon Sindermann
Thanksgiving dinner

With Thanksgiving just around the corner, kitchens across the country will soon be alive with the sights, smells and sounds of cooking. But what if we dove deeper into those recipe books and looked beyond the instructions? You might find you’re more than just a cook; you’re quite the chemist!  

Inspired by the popular show Lessons in Chemistry, an adaptation of Bonnie Garmus’s bestselling novel, cooking is presented as applied science, encouraging viewers to think critically about their cooking and the chemical reactions that create the flavors and textures they love. In this blog, we’ll explore the chemistry behind Thanksgiving cooking, revealing how different techniques bring out the best in each dish.

Third Annual Targeted Protein Degradation Symposium: Embracing the Excitement of Discovery

Posted on by Simon Moe

The third annual Targeted Protein Degradation (TPD) Symposium just wrapped up last month. It was kicked off with Poncho Meisenheimer, VP of Research and Development at Promega, likening the gathering of researchers to “kids in a biology candy store.” This playful analogy captured the vibrant energy and sense of exploration among the attendees, who convened to delve into the future possibilities of proximity-induced degradation. Poncho left attendees with three key questions to consider throughout the symposium:

  1. How can we focus on quantitative measures of cellular events in relevant models?
  2. How do we generate results that serve both human and AI models?
  3. How do we best embrace the excitement of discovery?

Nearly 150 participants from both industry and academia attended the two-day symposium. It was held on September 11th and 12th at Promega’s R&D hub, the Kornberg Center, in Madison, Wisconsin. The event, now in its third year, provided a familiar environment where collaborations flourished, and many attendees rekindled connections forged through previous interactions or partnerships in the field.

The Casual Catalyst: Science Conversations and Cafes

Posted on by Michele Arduengo

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).

More Than a Scientist: Paraj Mandrekar’s Career & Contributions to Tabletop Roleplaying Games

Posted on by Riley Bell

Paraj Mandrekar began his career at Promega in 1998 in the Genetic Identity Research and Development program. In 2001, he was a consultant at the World Trade Center to help meet the urgent need to identify victims of the 9/11 attacks. Two products, one of them being our DNA IQ™ System, that Paraj and others used for automating forensic DNA purification at the time were featured in the R&D 100 Award in 2002.

As he progressed through the successive ranks in R&D, Paraj took on more responsibility for the research, design, and development of novel chemistry. A significant high point in his career was being promoted to Senior R&D Scientist 1 in 2010. At that point, he was working on both forensic and non-forensic chemistries with paramagnetic particles. Promega’s non-forensic kit (AS1290) was launched with a new chemistry in March 2010, and a few months later, he got a new version of the Maxwell forensic sample kit (AS1240) out the door.

Myths, Misconceptions and Debated Theories in Biology

Posted on by Shannon Sindermann

Research studies and novel discoveries continually reshape our understanding of the natural world, often refining—and sometimes contesting—prevailing scientific theories. While this influx of new information is important for expanding knowledge, it can also give rise to myths and misconceptions stemming from biases, media misrepresentations and overgeneralizations. In this blog, we’ll explore misconceptions that blur the lines between fact and fiction, some scientific myths that just won’t go die and theories that scientists can’t stop debating.

Humans Only Use 10% of Their Brain 

This myth, frequently perpetuated through movies like Lucy with Scarlett Johansson and Limitless with Bradely Cooper, has ambiguous roots. Some attribute this pseudoscience to Albert Einstein, despite no recorded record of such a claim, while others associate it with a misinterpretation of William James and his “Reserve Energy Theory” (8).

To Tweet or Not to Tweet: Microblogging for Science Communication

Posted on by Kerstin Hurd

Microblogging is a form of blogging characterized by a shortened format and frequent posting schedule. Instead of personal websites, microblogs reside on social media platforms or apps, making them accessible to interact with and post on smartphones. Microblogs focus on interacting with audiences directly. With the ability to reply to or repost content, microblogging is more conversational and collaborative with audiences than long- form writing.

After its founding in 2006, Twitter (recently renamed “X” by its new owner) quickly became the face of microblogging platforms. Users publish content to the platform in posts of 280 characters that can include images, gifs, videos, and what the platform is most known for: hashtags. Hashtags enable users to search the platform by topic to connect with or follow other users who are writing about those topics. Users can also interact with each other by liking or retweeting tweets, which posts them to their own account. The open forum discussion style makes it possible for individuals to share their stories, offering first-hand accounts of breaking news and fueling political movements such as the Women’s March and Black Lives Matter.
