Computer analysis of the genomes of extremophiles — organisms that live in extreme environments — reveals that their living conditions are recorded in their DNA.
New research suggests the gut bacteria of red and grey squirrels differ significantly, potentially explaining the decline of the native red and the success of its grey counterpart.
The organisms living in your gut microbiome can influence your mental and physical health. Researchers have developed a way to better test for those biological effects.
Much like our gut microbes, the community of microbes used to process human waste must be healthy to do the job well. Monitoring the DNA in waste sludge can help us ensure the system stays healthy.
The current treatments for inflammatory bowel disease do not work for everyone. Tapping into new areas of biology may be the key to developing new therapies.
Probiotics are great for your gut, but which sources contain the most beneficial bacteria? Newly developed sensors are helping scientists figure it out.
The contrasting realities of antimicrobial resistance between high-income countries and low- and middle-income countries demands international co-operation to effectively fight superbugs.
Australia is one of the highest users of antibiotics in the developed world. So when do we actually need antibiotics to treat an infection? And when should we avoid them?
We’ve all heard of antibiotic resistance. The same thing is happening with other causes of infections in humans: fungi, viruses and parasites. This is making thrush and other infections hard to treat.
