We can fine-tune bacteria using algorithms to help them produce the things we need, from antibiotics to methane.
Spending more time in nature may be associated with less fear of germs.
A fear of microbes, like germs, could be harming human health.

Solutions to some of the globe’s most daunting environmental challenges may be closer than you think. Scientists are harnessing nature to clean up toxic chemicals and mining waste.
With an average shelf life of nine years, the coming tsunami of waste EV batteries needs action now.
Glaciers aren't sterile wastelands – they're chock-full of microscopic life.
Invisible to the eye, the microbial life in the air around us can vary depending on our environment.

Some face masks now come with a coating of graphene, a substance that can kill microbes. Is it safe to breathe it in?
Scientists are starting to use genetic information from bacteria to measure the health of vast areas of the ocean.

Whether or not you respond to a certain medicine or therapy doesn’t just depend on you. The microbes in your gut play a role in the success or failure of various drugs, including cancer therapies.
There are more viruses in the ocean than stars in the Milky Way – and they’re fundamental to Earth’s biodiversity.

The microbes in your gut influence how your immune system reacts to bacteria and viruses. A severe immune reaction is deadly; a small one lets the virus win. The right balance may depend on your diet.
More valuable than it looks.
Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.

If so, then the possibility of planetary super-heating in future has just become much more real.
The process of turning a newly dead animal into a bony skeleton relies on an explosion of life that ushers in decomposition.
Nutrients and energy contained within dead animals are repurposed and repackaged into living, breathing insects.
