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.

Rapid Test Identifies Wildfire Taint in Wine Grapes

Scientists have devised a new rapid and accurate test to enable wine producers to evaluate the effects of wildfire smoke damage on their crops prior to wine production. We spoke to Dr Wesley Zandberg about the new approach and how science is working with the wine industry.

Diamond Light Source in its Anniversary Year

The UK’s national synchrotron, Diamond Light Source, celebrates its double anniversary this year. 2017 sees them mark 15 years since the company was formed, and on the 19th October, they commemorated 10 years since their official opening by Her Majesty the Queen.

SWATH-MS Generates Highly Reproducible Data

Scientists looked to address the quantitative and qualitative reproducibility of SWATH-mass spectrometry (MS). The study concluded that detection of large numbers of proteins from highly heterogeneous samples is not only feasible but provides reliable and reproducible quantitative results.

New Crystal Structure of (Ph)PINK1 Aids Understanding of Early Onset Parkinson’s

Scientists have determined the crystal structure of PhPINK1 bound to it's substrate ubiquitin. Mutations of PINK1 are associated with early onset Parkinson's disease and it is expected that this information will help the design of Parkinson's therapeutics.

Pumpkins Hold the Key to Natural Disinfectants

Specific bacterial communities found on Styrian oilseed pumpkins were found to produce highly effective volatiles that inhibited the growth of both human and plant pathogens. The discovery has been applied to decontamination of hatching eggs which is currently performed using toxic formaldehyde.

Utilising Liquid Chromatography for Evaluating Toxic Histones in Packaged Fish

Researchers utilised liquid chromatography to investigate the effects of polyethylene packaging (PEP) in air versus vacuum packaging (VP) on deterioration of fish products, a common cause of scombroid food poisoning.
