After completing an undergraduate degree in Natural Sciences at the University of Cambridge in 2006, Karen became a research scientist at the Animal Health Trust, UK. During her time there, she completed a PhD in molecular microbiology and evolutionary genetics in partnership with the University of Cambridge and went on to hold a post-doctoral position. Her research focused on the fundamental biology of infectious diseases, outbreak analysis and the development of vaccines and diagnostic assays. In 2017 she left the lab to pursue a career in science communication. As senior science writer, Karen employs her wealth of knowledge and hands-on experience to coordinate and create a range of scientific content, tools and resources for the site and provide scientific support across the teams.

Microplastic Analysis and the Future Detection Landscape

The full impact that microplastics have on health and the environment is still not well understood, however, mounting evidence regarding their negative effects has made microplastics a topic of interest for scientists, governments and regulatory bodies. We spoke to Kathleen A. Young about microplastics detection techniques and technologies, the importance of standards and how regulations may come to fruition in the years to come.

A Step in the Right Direction for Dioxin Detection

To detect, quantify and ultimately instigate remedial action in relation to dioxin contamination, scientists require suitable analytical tools and techniques. The USEPA recently approved a new dioxin testing method which could assist these efforts. We spoke to Frank L. Dorman, PhD, FRSC, about the hazards posed by dioxins, challenges in their identification and the future detection landscape.

The Evolving Problem of Microplastics in a PPE Era

Microplastics are now ubiquitous in our lives and environment. To compound the problem, the advent of COVID-19 has seen uptake of single-use plastics in the form of personal protective equipment (PPE) skyrocket. We spoke to Kathleen A. Young about how the microplastics issue has evolved in light of COVID-19, particularly around PPE waste and what gains are being made in the areas of testing and analysis standards.

Leveraging Pseudoviruses in the Face of the COVID-19 Pandemic

The incredible efforts of scientists and public health agencies worldwide in response to SARS-CoV-2 has resulted in the emergency use authorization and rapid deployment of antibody-based countermeasures, including therapies and vaccines. Their effectiveness is typically measured in a neutralization assay, however, biosafety restrictions make working with SARS-CoV-2 challenging. We take a look at how pseudovirus may offer an alternative tool.

An Automated Age for Western Blotting

Western blotting has been a core technique in molecular biology for many years, however, optimization and reproducibility can be problematic. We spoke to Dr Alexandre Lucas about the automation of western blotting and the difference this advance is making to research.
Antimicrobial Resistance
Article

Antimicrobial Resistance

Antimicrobial resistance (AMR) is the ability of microorganisms to resist the killing capacity of antimicrobial drugs, a worryingly increasing problem. This article explores the science behind AMR, factors promoting its spread and techniques to detect it. Looking to the future, ways to combat AMR and alternatives to antimicrobials are discussed.
