2018 preview: Thousands of mystery lifeforms to be revealed
Bacteria and other microbes are all around us but we only know about 1 per cent of them. That is set to change, thanks to a technique called metagenomics
How good bacteria control your genes
Scientists have discovered a way that bacteria in the gut can control genes in our cells. Their work shows that chemical messages from bacteria can alter chemical markers throughout the human genome. The signal chemicals are made when bacteria digest fruits and vegetables. By communicating in this way, the bacteria may help to fight infections and to prevent cancer.
WHO urges development of new drugs for resistant bugs
A multidrug-resistant type of tuberculosis is at the top of the list of priority pathogens for developing new antibiotics, but at least three foodborne bacteria are also high-priority status. The foodborne pathogens of Salmonella, Campylobacter and Helicobacter pylori are near the top of the list of 20 antimicrobial-resistant bacteria identified by a World Health Organization...
Cystic fibrosis bacterial burden begins during first years of life
Cystic fibrosis shortens life by making the lungs prone to repeated bacterial infections and inflammation. Researchers have now shown for the first time that the lungs' bacterial population changes in the first few years of life as respiratory infections and inflammation set in. This research offers a way to predict the onset of lung disease in children with CF and suggests a larger role for preventive therapies, such as hypertonic saline.
Scientists find microbes on the skin of mice promote tissue healing, immunity
Beneficial bacteria on the skin of lab mice work with the animals' immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues.
Surfers may be swallowing bacteria and spreading it to others
Surfers seem to swallow more antibiotic resistant bacteria from polluted water than swimmers. They may also be spreading it to vulnerable people they know
Amoebae Give Black Death Bacteria a Safe Place to Hide
The simple amoeba — a single-celled organism found in the water and soil — may provide a safe haven for the deadly bacteria that cause the plague, a new study finds.
What species is most fit for life? All have an equal chance, scientists sayOlder articles »
There are more than 8 million species of living things on Earth, but none of them -- from 100-foot blue whales to microscopic bacteria -- has an advantage over the others in the universal struggle for existence.A trio of scientists report that regardless of vastly different body size, location and life history, most species are equally 'fit' in the struggle for existence.
