How do pathogens invade the lungs? Using human lung microtissues, a team has uncovered the strategy used by a dangerous pathogen. The bacterium targets specific lung cells and has developed a ...

The COVID-19 pandemic showed that predicting the invasion of a novel pathogen into the human population and its evolutionary potential to generate new variants is crucial for preventing future ...

Humans have been getting infected by ancient bacteria and viruses for at least 37,000 years. Now, for the first time, pathogen DNA has uncovered a pivotal disease "turning point" that happened 6,500 ...

The human intestine is home to a dense network of microorganisms, known collectively as the gut microbiome, which actively helps to shape our health. The microorganisms help with digestion, train the ...

Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.

Distinguishing between self and non-self is a critical ability of the immune system. Some pathogens have evolved proteins that resemble those of their host, a mechanism called molecular mimicry, in an ...

In a new genetic study, scientists have charted the rise of 214 human diseases across ancient Europe and Asia. By Carl Zimmer To prepare for future pandemics, scientists look to the past for clues.
