The immune system is a complex network of cells and chemicals that defend the body against harmful invaders like bacteria, viruses, fungi, and parasites. It includes various components such as ...

Pseudomonas bacteria infected by different mutations of a jumbo phage. The dot in the middle is the shield created by the phage to protect its DNA after it has infected the bacterial cell. Image by ...

Scientists built a model that allows them to diminish phage communities from a mouse gut microbiome -- and then bring them back -- without affecting the bacteria. On a test run of their model, ...

On average, most adults will catch two to three colds a year; children (partially because their immune systems are still ...

The laureates’ work focused on a specialised immune cell called regulatory T cells which prevent the body from attacking itself. When this system fails, the consequences can be devastating. Autoimmune ...

A petri dish full of dead bacteria isn’t usually cause for celebration. But for Stanford’s Brian Hie it was a game-changer in his efforts to create synthetic life. The perpetrator was a type of virus ...

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published today in Nature Biomedical Engineering, the Synthetic Biological ...

Each winter, cold and flu season reaches its peak. That leaves a lot of people dealing with coughing, sneezing and fevers. People often take fever reducers to lower their body temperature when they’re ...

University of Toronto researchers have made the first discovery of a virus that infects Legionella pneumophila, the bacteria ...

This project is not being offered for the current term. Please check back next semester for updates. The human gut is home to diverse microbes and has one of the highest density of microbes on Earth.

Viruses are so simple in their structure, they may not even qualify as living things. Yet, they are ruthless in their robotic ...
