Care in the Community – How Biofilms Improve Bacterial Survival
Article

A single bacterial cell on its own is vulnerable to attack and like many living things they can benefit from safety in numbers. But bacteria take communal living to a whole new level, forming veritable civilizations - the bacterial biofilm.

Antigenic Drift vs Antigenic Shift
Article

As part of the host-pathogen arms race, viruses are continually evolving to evade the host immune response, be it from previous infection or immunity acquired through vaccination. Here we take a look at the processes of antigenic drift and antigenic shift.

Exploiting Epigenetics in Cancer Treatment
Article

Changes to the complex of DNA and the proteins that form chromatin are important drivers in many cancers. We explore the challenges and progress in the development of new therapies targeting epigenetic regulators.

Exploring the Public’s Perception of Food Fraud
Article

When you go to the shops to buy the weekly groceries, it’s quite likely you’ll find yourself thinking about where your food has come from. Is this organic? Is that free-range? You are perhaps less likely to find yourself wondering, “Is this food fake?”

Understanding the Lytic Cycle – What Are the Steps?
Article

Bacteriophage (phage) are viruses that specifically infect bacteria. They have a two-phase lifecycle, residing in a dormant state within the host genome (lysogenic cycle) or hijacking the host cellular machinery for their own replication (lytic cycle). Here we will explore the important steps of the lytic cycle.

Cold Plasma for Seed, Fruit and Vegetable Decontamination and Plant Disease Control
Article

An effective way to increase crop yield is to minimize losses to pathogenic microorganisms by improving the disease resistance of crop plants. A recently emerging alternative to conventional methods for improving plant disease resistance is cold plasma.

Untargeted Profiling of Metabolites: In Search of Cancer Biomarkers and Antibiotics
Article

When you are examining a predetermined set of metabolites (in other words, when you know what you are looking for), targeted approaches can be adopted. But when a comprehensive profile of all the metabolites in a sample, known and unknown, is required, untargeted technologies are the way to go. Here, we look at how how untargeted metabolomics is helping science discover new biomarkers for cancer and natural antibiotic sources.

The Genetics of Coffee Consumption
Article

Marilyn Cornelis, of the Feinberg School of Medicine at Northwestern University, has spent years researching how coffee affects our body. In this interview, she explains how coffee affects our brain, interacts with cannabis, and why listening to your body might be the best way to decide how much coffee to drink.

MALDI Imaging Mass Spectrometry (MALDI IMS): A Marriage of Mass Spectrometry and Morphological Spatial Resolution
Article

Matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI IMS) is a powerful analytical technique that enjoys the sensitivity of mass spectrometry coupled with spatial distribution information.

Above the Genome: How Epigenetics Influences Cancer and Obesity
Article

Truly understanding how our DNA influences our lives and health sometimes means moving past the DNA sequence. Epigenetics encompasses a group of heritable modifications without changes to the DNA sequence itself. Our epigenetics affects our susceptibility to a staggering number of diseases, including both cancer and obesity.
