Viruses Aren’t All Nasty – Some Can Actually Protect Our Health

Viruses are mostly known for their aggressive and infectious nature. It’s true, most viruses have a pathogenic relationship with their hosts – meaning they cause diseases ranging from a mild cold to serious conditions like severe acute respiratory syndrome (SARS). They work by invading the host cell, taking over its cellular machinery and releasing new […]

Helium Ion Microscopy Reveals Phage-Bacterium Interaction

Bacteria and viruses can be imaged with helium ions in contrast to electrons, which are the standard workhorse in nanoscale microscopy, an interdisciplinary research consortium from the Nanoscience Center at University of Jyvaskyla in Finland has found. Helium ions, being more massive than electrons, can be focused to a much tighter spot down to the […]

Phage Therapy Effective For Drug Resistant Lung Infection Treatment

Phage therapy may be a safe and effective antibiotic alternative for the treatment of cystic fibrosis lung infections, scientists from the University of Liverpool’s Institute of Infection and Global Health have shown. Chronic lung infections caused by the bacterium Pseudomonas aeruginosa are becoming increasingly difficult to treat due to antimicrobial resistance (AMR). With limited alternative […]

Microbial Therapeutics With Thermal Bioswitches For Cancer

To battle cancer and other diseases of the gut, we could one day use genetically altered bacteria that release medicines to tumors or the gut. A new study performed using mice demonstrates how doctors might one day better regulate those therapeutic microbes by engineering them to respond to temperature. For instance, if engineered bacteria were […]
