Wastes from facilities like this cheese factory could find uses in agriculture.
Leftover lactose from cheese production shows early promise as a treatment that can help soils retain water and nutrients, making them more resistant to drought.
Human poo is a concoction made up mostly of water with a sprinkling of the solid stuff.
Around 75% of our faeces is made up of water. The other 25% is the good stuff, including bacteria, viruses and undigested food.

Regular hand washing is important not only to keep from getting the flu but also to prevent passing it to others, such as young children and seniors, who may be even more vulnerable. Here's how.

Wetlands are some of the world's most undervalued weapons against climate change. They store huge quantities of carbon – but without better protection, many could soon be drained or paved over.
We can create the right kind of food plants to survive on Mars.
If humans are to live on Mars they will need a stable supply of food. Earth plants are not suited to the Mars climate but we can engineer plants that are.
Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
Following NASA's latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
An ingredient in toothpaste and other personal care products may be harming the microbes in our gut and leaving us vulnerable to disease.
Triclosan is found in thousands of personal care products from toothpaste to soap. New research links it to inflammation and cancer in the gut in mice, by disrupting their microbiome.
Though examining poop samples scientists working on the American Gut Project are getting a new perspective on the microbes in our guts.

In the largest citizen science experiment to date, 11,336 people sent poop samples to this San Diego lab so that microbiologists could figure out how the microbes in our guts make us healthy or sick.

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?

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.
