Transforming Your Fear In Meetings

During the summer after my junior year of undergrad, I worked as a marketing intern for a health education nonprofit. I was a biology major, but by this time I knew I wanted to pursue a career in science writing, and this internship was my first real-world experience. It was an amazing summer, and by the time I walked into my exit interview, I was confident that my supervisor was pleased with my performance. However, she shared a piece of feedback that caught me off guard.

Superior Support to Automate and Scale-Up Your Workflows with Ease

Automating a workflow can be a tedious and challenging process that requires lots of time and resources. A helping hand can make all the difference, as it did for Stephanie Dormand, Molecular Supervisor at UniPath Women’s Health, a diagnostics lab located in Denver, Colorado. 

See how Promega Field Service Support staff helped one laboratory automate and scale-up sample processing to improve laboratory workflow. Promega Scientist at a liquid handler.

The women’s health molecular testing service at UniPath primarily relied on the tabletop Maxwell® RSC Instrument to conduct nucleic acid extractions using the Maxwell® Viral TNA Kit. As their testing needs grew, they required more throughput. Dormand worked with Promega Field Support Scientist Rick Grygiel to implement the Maxwell® HT Viral TNA Kit on the Tecan Fluent 780 liquid handler, raising their throughput from 16 to 96 samples per run. When COVID-19 struck, Dormand worked with Rick to quadruple their testing with the addition of another Fluent 780.

Antibody Correlates of Protection for mRNA Vaccine

Identifying correlates of protection, or biological markers that correlate with a certain level of protection from disease helps public health experts assess vaccination performance. Picture of a COVID-19 vaccine vial.

In the rapidly shifting context of a pandemic, public health officials need a way to quickly assess how vaccinations perform in changing situations. One approach is to identify correlates of protection, or biological markers that correlate with a certain level of protection from disease. This tool is used to assess the design and formulation of annual influenza vaccines, as immune system markers that correlate with protection from flu can give developers a sense of how effective the vaccine might be for different population groups. Though they are not a replacement for rigorous clinical trials, correlates of protection can provide meaningful and predictive data for vaccine developers with smaller trial sizes and less time.

A study published in November 2021 indicated that levels of binding antibodies and neutralizing antibodies for the SARS-CoV-2 virus in blood serum are correlates of protection for Moderna, Inc.’s COVE phase 3 clinical trial of their mRNA COVID-19 vaccine.

What is nonalcoholic fatty liver disease (NAFLD)?

NAFLD is not a simple disease, it is an umbrella term for a range of liver conditions. The main defining characteristic of NAFLD is fat accumulation in the liver, called steatosis. In about 20% of people, steatosis is accompanied by inflammation, which is a more severe form of NAFLD called NASH (nonalcoholic steatohepatitis). NASH can progress to more advanced conditions like liver cirrhosis and liver failure. Most of the time, NAFLD is associated with underlying conditions—it is closely related to metabolic dysfunction, obesity, and type 2 diabetes. To better reflect the disease pathology, there has been a lot of discussion in the field recently to rename NAFLD to MAFLD, for metabolic associated fatty liver disease. Even though NAFLD has been studied for many years, the causes and progression of the disease are still not well understood. There are no FDA-approved diagnostic tools or treatments for it yet.

Real-Time Analysis for Cell Viability, Cytotoxicity and Apoptosis: What Would You Do with More Data from One Sample?

Originally posted May 25, 2017. Updated 2022

You are studying the effects of a compound(s) on your cells. You want to know how the compound affects cell health over a period of hours, or even days. Real-time assays allow you to monitor cell viability, cytotoxicity and apoptosis continuously, to detect changes over time.

Why use a real-time assay?
A real-time assay enables you to repeatedly measure specific events or conditions over time from the same sample or plate well. Repeated measurement is possible because the cells are not harmed by real-time assay reagents. Real-time assays allow you to collect data without lysing the cells.

Advantages of  Real-Time Measurement
Real-time assays allow you to:

Making Sense of Climate Change

Earlier this year, I had an opportunity to attend a virtual talk presented by leading climate scientist and communicator Dr. Katharine Hayhoe. She began by asking the audience to send in one word that describes how they feel when thinking about climate change. The responses popped up live in a word cloud on Hayhoe’s shared screen:

Anxious

Frozen

ARGHH!

Those words also describe how I felt when I realized the conclusion to my series of blogs on the 2021 Nobel Prizes would address the topic of climate change.

Linking Evolution to Pregnancy Outcomes: A Study in Gene Expression

Many of the traits characteristic to human pregnancy are unique. In contrast to other mammals, human pregnancy and labor last longer, and humans are more prone to complications, including infertility, preeclampsia and preterm birth. Research recently published in eLife Sciences by Vincent Lynch, PhD, and colleagues explores the history of gene expression in the human uterus, how it differs from other mammals and how changes in expression may be implicated in our susceptibility to disease.

This study is part of the emerging field of evolutionary medicine, where researchers apply modern evolutionary theory to help us understand the mechanisms behind human health and disease. By studying the history of gene expression, researchers and physicians can illuminate the pathways through which evolution has guided the development of modern tissues and organ systems, and how these systems may differ in one species versus the next.

Finding the Latest Science News While On the Go

Today’s guest blog was written in collaboration with Melissa Martin, a former global marketing intern with Promega. She is a senior at the University of Wisconsin-Madison where she is double majoring in zoology and life sciences communication, with a certificate in environmental studies.

Have you ever found yourself wondering what the newest advancements were on genetically engineering plants or using artificial intelligence in biotechnology but didn’t know where to start looking? You most likely know the basic science behind the headlines, but a general web search may lead to dramatized articles that focus more on getting attention than being accurate. Or you might find a scholarly article that will offer in-depth, peer-reviewed information but may require more time to read than you are willing to give.

Resume vs. CV — What Is the Difference?

Today’s guest blog is written by Sophie Mancha, a former global marketing intern with Promega. She is in her 4th year as a PhD candidate in the Biomedical Engineering Department at the University of Wisconsin-Madison, studying pancreatic cancer.

Whether you are applying for a scholarship or trying to land a position in a research lab, there are plenty of decisions to make. Arguably, the most critical consideration is what documents to include to showcase that you are the right person for the job. Specifically, should you be preparing a curriculum vitae (CV) or a resume? What exactly is the difference?
