You may think that your milk-drinking, ice cream-licking days are behind you as you battle the discomfort of lactose intolerance. But there maybe be a way to reverse the situation.
Drug discovery can get an assist from what nature’s already devised.
As antibiotic resistance increases globally, the heat is on to find new alternatives to treat infections. Chemists can get a head start by looking at compounds produced in nature by fishes' microbes.
An increase in colorectal cancer in adults younger than 50 is troubling to doctors and often tragic for patients.
Colorectal cancer rates among older adults have been declining, but diagnoses in adults younger than 50 have increased. As Colorectal Cancer Awareness Month winds down, a researcher offers insight.
A new body of research suggests that infections in childhood, along with antibiotic use, could impact the bacteria in our intestines and raise risks of mental health challenges in later life.
Research using massive databases -- such as the Danish Psychiatric Central Research Register -- is enabling a whole new understanding of the links between life history, the gut and mental health.
Millions of Americans suffer from food allergies.
There has been a dramatic rise in life-threatening food allergies in the last few decades. Antibiotics, poor diet and C-sections have all been implicated. Now new evidence points to gut microbes.
The microbes that live in our gut are essential to good health.

When immigrants come to the US, it isn't just the people who assimilate. The microbes in their gut also become Westernized after living here. This may predispose them to diseases like obesity.
Hand washing is an effective way to help prevent the spread of bacteria.
Millions of bacteria live on our skin without making us sick. It's when they manage to get through that they can be dangerous – particularly if they're resistant to antibiotics.
Every surface of our body – inside and out – is covered in microorganisms: bacteria, viruses, fungi and many other microscopic life forms.
Just because you don't have the flu doesn't mean that your aren't teeming with viruses inside and out. But what are all these viruses doing, if they aren't making you sick?
Put down that bleach.
A sanitised environment can mean fewer helpful bacteria. That has some surprising consequences for the health of children.

Many probiotic bacteria don't manage to colonise the gut, but that doesn't mean they don't have positive health benefits.
Don’t scratch it!
Mosquitoes are picky about who they bite but it's not actually "us" that they're smelling when they choose their next meal...

Cancer immunotherapies are considered as revolutionary. But many cancer patients don't respond to them. In a new clinical trial, researchers are testing whether gut microbes are the key to remission.
Clinical trials involving probiotics are failing to report on the safety and harms of these treatments.
Gut microbe composition is fairly similar across a range of diseases.
Certain gut microbes have been associated with certain diseases, but a new study finds that the pattern of microbes is consistent across a range of diseases.

A new type of antibiotic uses DNA to fight a common deadly microbe, Clostridium difficile. These new drugs are inexpensive and adaptable and can be modified to target any bacterium, lowering the chance of drug resistance.
By the time they turn one, half of Australian babies have had a course of antibiotics.
There may be additional long-term health harms from antibiotic exposure in early life and before birth, including an increased risk of infection, obesity and asthma.
Manipulating environmental exposures to optimize a healthy microbiome may hold the promise of preventing chronic inflammatory diseases, such as Crohn’s disease and ulcerative colitis.
Halting the rapid rise in inflammatory bowel disease will require a proactive approach to medicine, and a focus on the gut.
The immune system has to establish which cells belong to us and which are foreign, no mean feat.
Nobel laureate Peter Doherty explains immunity.
