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.

A “Losing” Proposition: Tackling the Problem of Lost or Unrecovered Analytes in Chromatography

Liquid chromatography has proven to be an invaluable tool in analytical labs. However, despite being a “mature” technique, there are still some areas that prove problematic, leading to suboptimal results. One such area is the loss of analytes during the chromatographic process, but design innovations are aiming to overcome this problem.

A Leading Voice for T-Cell Expertise During COVID-19 and Beyond

The unprecedented scale of global scientific collaboration, including the establishment of expert consortia, has played an important part in addressing the COVID-19 pandemic. We spoke to Professor Danny Altmann, chair of the Global T cell Expert Consortium (GTEC) about the role that T cells have in viral infections like SARS-CoV-2 and what GTEC is hoping to achieve.

Kombucha Inspires Creation of a Microbial “Living Material”

Scientists have created a “living material” made from microbes that can respond to stimuli from their surrounding environment. It is hoped the material could find diverse applications in contaminant detection, highlighting damage, for example, to packaging, delivering nutrients or therapeutics and even in creating living photographs.

Bringing Speed and Simplicity to SEM-EDS Analysis

While many researchers combine scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS) to examine materials for defects at the micro-scale, the process is often viewed as slow and complex. Fortunately, however, advances in SEM-EDS analysis are bringing a new level of speed and simplicity to failure analysis.

Taking Cultured Meat to the Next Level

In a study published in Metabolic Engineering, bovine cells were engineered to endogenously produce phytoene, lycopene and β-carotene. We recently had the pleasure of speaking to Andrew Stout, lead author of the study, to learn how these cells were created and explore some of the benefits of engineering in the abilities to produce additional nutrients.

Single-Cell, "Multi-Omics" Analysis Uncovers a New Stage in Immune Cell Formation

A research team from The Walter and Eliza Hall Institute has adopted a single-cell, multi-omics approach to explore this question, focusing particularly on T and B lymphocyte formation. They discovered a new stage in lymphocyte development, information which the researchers say could "enrich future studies of the immune system". We wanted to know more.
