Nice to see you: parrotfishes prey on seaweed, which consume seaweeds that can outcompete, smother or even poison corals.
A combination of factors – pollution, disease and overfishing – is harming corals but scientists have found clues to effective treatment by studying corals' microbiome.
The types of bugs that may be calling your lungs home.
Understanding the bugs in our lungs could help treat certain diseases, including asthma.
Horse poo clues point the way.
Microbes reveal that the great Carthagian general Hannibal may have taken a surprisingly difficult route to get to Italy.
Why are some new parents wiping vaginal fluid all over their baby’s mouth, eyes, and skin?
For years, we’ve known that brain activity can affect our gut.
Could it be that in some cases, changes in the gut are actually driving mood disorders rather than the other way around? Mounting evidence suggests this is likely to be the case.
Probiotics are live microorganisms that have been delivering health benefits for thousands of years by helping to establish healthy gut microbiota.
The human gastrointestinal tract harbours trillions of microorganisms, with up to 1,000 or so different bacterial species.

Don’t undo all your good work by eating this on the weekend.
Yo-yoing between eating well during the week and bingeing on junk food over the weekend is likely to be just as bad for your gut health as a consistent diet of junk.
Being too clean isn't what's making us sick. It's the loss of biodiversity in the bacteria and organisms that live in our bodies and work with the immune system.
Acid busting PPIs may have some downsides.

PPI drugs are widely used to suppress gastric acid, but they could come with some risk to our 100 trillion gut microbes.
While nutrient supplementation can have a role in treating certain psychiatric disorders, all kinds of nutrients should, in the first instance, be consumed as part of a balanced wholefood diet.
A growing body of research points to the detrimental effect of unhealthy diets and the protective value of healthy diets – along with select nutritional supplements as required – for maintaining and promoting mental health.
The modern emphasis on sanitation has a role in our shrinking microbial populations.
Human activities have altered whole ecosystems with declines in species diversity, extinctions and the introduction of weeds and pests. But it's not just the outside world we're harming.
Allergies are becoming more frequent in the western world.
Allergies are reactions caused by the immune system as it responds to environmental substances that are usually harmless. But we don't yet have a cure or the ability to prevent them from developing.
When we think of antibiotic overuse, we don't generally think of allergies. Research is beginning to suggest that maybe we should.
I can’t believe it isn’t true.

Most people who report allergies don't actually have them – and there are other things you may find surprising.

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.
Gut bacteria can manufacture special proteins that are very similar to hunger-regulating hormones.
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…

One of medicine’s greatest innovations in the 20th century was the development of antibiotics. It transformed our ability to combat disease. But medicine in the 21st century is rethinking its relationship…
