Put down that bleach.
A sanitised environment can mean fewer helpful bacteria. That has some surprising consequences for the health of children.
Magnetotactic bacteria owe their special property to the magnetic nanoparticles they contain.
These single-celled organisms naturally respond to the Earth's weak magnetic field. Scientists are untangling how it all works, looking to future biomedical and other engineering applications.
When bacteria change, antibiotics can stop working.
Antibiotic resistance is a major and growing global health threat. These five recent examples show us how dangerous it can be.
DNA knot as seen under the electron microscope.
Mathematical models can describe the many shapes of DNA, as well as cellular processes like DNA replication.
There are countless nanoscopic architectures in nature, creating iridescence, sticky feet, magnetic navigation – and more.
The average office desk is said to contain 400 times more germs than a toilet seat.
Bacteria exchange genes easily, but a newly discovered set of rules that regulate these exchanges could help us to prevent the spread of antibiotic resistance.
The discovery of molecular rules that regulate the transfer of genetic material between bacteria could help prevent the spread of antibiotic 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.
If you eat a healthy diet, it’s probably not worth it.
Probiotics have been proclaimed by many as the answer to all sorts of health issues and conditions. But what exactly are probiotics? And, more importantly, should you be taking them?
Faecal bacteria on hands is really common.
Handshakes may be polite, but they're also a sure fire way to transfer lots of bacteria from one hand to another.
Following NASA's latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
With all the different types of yogurt on offer, making a decision on which one to buy can be difficult.
Consuming yoghurt is associated with many health benefits. But with all the varieties of yoghurt, and added ingredients like fruits and probiotics, it can be hard to know which is best for your health.
No mother wants their baby to develop jaundice, but it turns out that they should probably be grateful.
A low diversity of gut bacteria may help explain heart attacks in young people, women and certain ethnic groups.

The "sniff test" doesn't work every time, and other food safety tips.
Sugar mama? Researchers are teasing out the benefits of various molecules in human milk.
A chemist explains how some molecules in human breast milk help fight infection. Understanding their properties could lead to better infant formulas that share the health advantages of breastfeeding.
Eczema, which is common in babies, is itchy and painful.
In this clinical trial, the first of its kind, physicians explore whether directly applying a 'good' strain of bacteria to the skin can heal eczema
Cancer is the leading cause of death in the world.

Synthetic biology allows us to engineer biological cells. This could help us tackle cancer in remarkable ways.
From a human perspective, some strains are good, some are evil.
E. coli bacteria are the frequent culprits behind outbreaks of food-borne illnesses. But not all strains are harmful; some are even helpful.
New research has found a way to speed up enzymes that break down the PET plastic in bottles.
