If we find microbes on Mars, it will be difficult to exclude the possibility that we have accidentally brought them there from Earth.
Not all bathrooms are clean, which poses a problem for holiday travelers trying to keep their hands clean.
With holiday travel in full swing and people packed together in small spaces, it's important to try to stop the spread of germs. But can we really get our hands clean with a few seconds of cold water?

Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.

Humans - the very "carriers" who can spread dangerous microbes unthinkingly from their equipment and shoes - can instead become the first line of defence against a possible microscopic invasion.
A range of pathogens might be lurking in makeup testers, from the mild to the deadly.
Bacteria cultured from a sample of air in a public building.
When jetting off on holiday, we rarely give a second thought to what microbes we might be taking with us. But humans spread trillions of bacteria around the globe, potentially harming ecosystems' balance.
Help us put this old wives' tale to a scientific test.
Some E. Coli protect humans from more harmful strains.
Sometimes the enemy of your enemy is your friend.
It helped them conquer the world, three billion years ago.
Healthy soil teems with bacteria, fungi, viruses and other microorganisms that help store carbon and fend off plant diseases. To restore soil, scientists are finding ways to foster its microbiome.

The volcanoes would be a great place t to search for fossilised microbes.
Drug-resistant strains of gonorrhoea, once easily dispatched with penicillin, are spreading across the globe resulting in chronic pain and sterility.
Without leading edge innovations and coordination, Canadians will die from the epidemic of antibiotic resistant infections.
Just as organisms that infect us make changes in us - we too make changes in them and they grow and adapt to their human hosts.
Humans play host to many little passengers. Right now, you’re incubating, shedding or have already been colonised by viral, bacterial, parasitic or fungal microorganisms - perhaps even all of them.
Trillions of microorganisms live inside your gut.
Trillions of microorganisms living inside your digestive system may influence your health and even your weight. Here's how your gut may communicate with your brain, bone marrow and immune system.
Modern diets are changing the compositions of our gut microbiota, and with that, our personalities.
For most of the twentieth century, we were at war with microbes, leading to substantial changes in our body's ecosystem. This has changed our diets, disease profile, moods and even personalities.
Those keypads are teeming with microbes.

What's on your cash? Studies show our money carries everything from pet DNA and old food to E.coli and traces of cocaine.
Open wide … the mouths of crocodiles like this contain bacteria that cause potentially lethal infections in people they bite.
Until recently we didn't know much about which antibiotic is best for people who have been attacked by a crocodile.

New findings make it hard to imagine a more important goal for solar system exploration than searching for microbial life in Enceladus' internal sea.
