Researchers simulated thousands of scenarios of an ancient pathogen being released into modern ecosystems. In the worst cases, up to one-third of host species were destroyed.
Dangerous fungal infections are on the rise globally. But we have few drugs that work and no prospect of anti-fungal vaccines any time soon.
A virus’s genes hold a record of where it’s traveled, and when.

After a nose swab tests positive for a virus or bacteria, scientists can use the sample’s genetic sequence to figure out where and when the pathogen emerged and how fast it’s changing.
Microbes are everywhere – and they aren’t all friendly.

Scientists get up close and personal with deadly pathogens to give doctors the tools they need to treat people sickened by germs. The key is keeping the researchers – and everyone around them – safe.
Children in the study seemed to display a very strong “innate” immune response.
Institutions like hospitals and transit systems have been using UV disinfection for years.

UV disinfection is a proven means of killing pathogens like the SARS-CoV-2 virus, but it’s not risk-free.
Ordinary food coloring suspended in tiny droplets in the air can generate oxygen free radicals that collide with airborne virus particles.

People have lived with infectious disease throughout the millennia, with culture and biology influencing each other. Archaeologists decode the stories told by bones and what accompanies them.
Immune cells release proteins called cytokines which alert the rest of the immune system that a virus is present.
We blame the coronavirus for the thousands of deaths, but it is actually a hyperactive immune reaction that is the cause of death. An immunologist explains.
Your body wants you to freak out about germs so you avoid them.

Human psychology has evolved to avoid situations that could lead to infection. Behavioral choices now could have long-term effects on how people interact with others and the world.

The COVID-19 pandemic may trigger large-scale disruptions such as school closures, event cancellations and movement restrictions.

A key component of how the coronavirus could be spreading is the environment.
Places where lots of animals come into contact can help pathogens move from species to species.

In the real world, new diseases emerge from complex environments. To learn more about how, scientists set up whole artificial ecosystems in the lab, instead of focusing on just one factor at a time.
Whether by biology or behavior, some people in the crowd will transmit coronavirus to more than the average number of others.

The novel coronavirus spreading outward from Wuhan, China, will get an assist from a subset of infected people who transmit it to many others.
What happened to make plague able to cause devastating epidemics, as in this depiction from 1349?

People caught and died from plague long before it caused major epidemics like the Black Death in the middle ages. Could what scientists call cultural resistance be what kept the disease under control?
Spraying insecticide to kill mosquitoes: Mosquitoes are vectors of many devastating diseases such as malaria.
In the ongoing arms race to kill off mosquitoes that spread malaria, researchers have modified a naturally occurring fungus that kills mosquitoes with a deadly toxin to wipe out these insects faster.
Once a respiratory virus like influenza has entered your home or workplace, it is wise to treat the space like a hospital and practice infection prevention and control.
From face-touching to virus-contaminated electronic devices, a scientist offers some tips on eradicating the flu virus from your home.
A virus like SARS can shut down cytokine production, enabling it to multiply to higher levels and causing significant infection and even death.

We’ve all endured infections. Here’s how it works when our bodies are attacked by viruses, bacteria or parasites, and our innate immune system becomes the first line of defence.
When governments delay releasing information about disease outbreaks, algorithms come to the rescue.
The original antigenic sin has made fighting diseases really difficult.
Innovative initiative aims to inspire pupils on the continent to take up careers in science.
