Microbes: Our tiny, crucial allies

Long viewed simply as ‘germs,’ the hidden half of nature turns out to be crucial to the health of people and plants.
Tackling antimicrobial resistance relies on us tackling the interrelated areas of human, animal and environmental health. from www.shutterstock.com

Why the health and agriculture sectors need to work together to stop antibiotic resistance

The federal government is tackling antimicrobial resistance with a ‘One Health’ approach. But what is One Health and what can it offer that other approaches haven’t?

How many genes does it take to make a person?

The answer – fewer than are in a banana – has implications for the study of human health and raises questions about what generates complexity anyway.
It’s bacterial biofilms that give the Grand Prismatic Spring its colorful hues. Karin Sauer

Unlocking the secrets of bacterial biofilms – to use against them

The vast majority of the bacteria that surround us are not free-floating but prefer to band together in cooperative communities called biofilms. How do biofilms form and cooperate?

Bacteria found to thrive better in space than on Earth

One common terrestrial bacterium has been found to grow in the microgravity of the International Space Station than on Earth, although it remains a mystery why.
Baby it’s warm inside … we have 200 microbes for every human cell. Agricultural Research Service

Are you overweight? The clue’s in your poo

Our personal collection of microbes is vital for gut health - but new research shows that large-scale analysis of our ‘microbiomes’ can show if a population is fat or lean. The answer is in sewage.

How the bacteria in our gut affect our cravings for food

We’ve long known that that the gut is responsible for digesting food and expelling the waste. More recently, we realised the gut has many more important functions and acts a type of mini-brain, affecting…

Households are new source of antibiotic-resistant superbug

Human skin is a garden of microbes which is home to about 1,000 bacterial species. Most are benign but some invade the skin and cause illness – and of these, antibiotic resistant bacteria are particularly…

Education, breastfeeding and gender affect the microbes on our bodies

Trillions of microbes live in and on our body. We don’t yet fully understand how these microbial ecosystems develop or the full extent to which they influence our health. Some provide essential nutrients…

Scientists pinpoint when harmless bacteria became flesh-eating monsters

Bacterial diseases cause millions of deaths every year. Most of these bacteria were benign at some point in their evolutionary past, and we don’t always understand what turned them into disease-causing…

Good vs bad bacteria: the bugs responsible for Crohn’s disease

New links between the bacteria in your gut and disease are being made almost daily. We know, for instance, that the microbial communities residing in your intestines have a role in your mood and levels…
Trypanosomes in the blood. Wendy Gibson

Caught in the act: microbes do have sex

There is no denying that humans think sex is important, but it also matters for microbes. Sex allows genes from two parents to be mixed, leading to new combinations of genes in the offspring. In the past…
The trillions of bacteria in your gut can affect your brain – psychologically and physically. Helga Weber

Navel gazing: healthy gut bacteria can help you stress less

Striking new evidence indicates that the gut microbiome, the ecological community of microorganisms that share our body, has a huge effect on brain function – much larger than we thought. It has long been…
