Computer analysis of the genomes of extremophiles — organisms that live in extreme environments — reveals that their living conditions are recorded in their DNA.
The Nobel Prize-winning Luria−Delbrück experiment showed that random mutations in bacteria can allow them to develop resistance by chance.
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.
Chronic UTIs come back repeatedly or never fully go away despite treatment.
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.
The science of smell is an exciting area of research.
New technology could unlock the soil-enriching nitrogen-fixing ability of legumes…and one day apply this to other crops too.
Your mouth and your gut is full of them. But we don’t know if they’re friend or foe.
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.
Keeping wounds clean and infection free has challenged people for thousands of years.
While every week or two will generally suffice for sheets, towels are best washed every few days. A microbiologist explains.
Zosurabalpin is highly effective against dangerous bacterium Crab, which can kill up to 60% of people infected with it.
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.
Gut bacteria consume the nutrients that harmful pathogens need to survive, thereby keeping them in check, a new study finds.
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.
Developing new antibiotics is important in the fight against antibiotic resistance. But we also need to use the antibiotics we already have much more wisely – GPs play a major role in this.
The meadow spittlebug can transmit a deadly bacterium – many plants in Britain could be at risk.
