Fire may be key to reviving dogwood trees

Proper and timely burning of some Eastern U.S. forests could help revitalise flowering dogwood trees, which benefits a wide range of species, a Purdue University report shows.

Uncovering the Mystery of a Major Threat to Wheat

Scientists have solved a longstanding mystery as to why a pathogen that threatens the world's wheat supply can be so adaptable, diverse and virulent.

Superbug's CPU revealed

A team of researchers has revealed that a small chemical, made by the superbug Staphylococcus aureus and its drug-resistant forms, determines this disease's strength and ability to infect.

Structure of anti-HIV immune molecule

In findings that contribute to efforts to design an AIDS vaccine, a team of scientists has determined the structure of an immune system antibody molecule that effectively acts against most strains of human immunodeficiency virus, the virus...

From microbe to hydrogen fuel

Scientists have investigated a means for enhancing the efficiency of clean energy production by using specialised bacteria.

Powerful genome barcoding system

Genetic abnormalities are most often discussed in terms of differences so miniscule they are actually called "snips" - changes in a single unit along the 3 billion that make up the entire string of human DNA.

Robots offer vaccination packaging accuracy

When it comes to packaging life-saving and expensive pharmaceuticals, robots provide a precision that not only meets stringent safety guidelines but also improves efficiency. Claudia B Flisi reports.

Bacteria could improve digestive health

The researchers used a colony of mice raised in a large plastic bubble, called an isolator, that was completely sterile, lacking even a single bacterium.

Overcoming anthrax's natural defences

Army scientists have discovered a way to "trick" the bacterium that causes anthrax into shedding its protective covering, making it easier for the body's immune system to mount a defence.

Treatment of gums may lower blood sugar

Recent research suggests that the treatment of serious periodontal disease in diabetics with Type 2 diabetes may lower their blood sugar levels.

Suppressing activity of common intestinal bacteria

Researchers has discovered that common intestinal bacteria appear to promote tumour growths in genetically susceptible mice, but that tumorigenesis can be suppressed if the mice are exposed to an inhibiting protein enzyme.

Diatoms reveal freshwater pollution

Researchers in India have demonstrated that microscopic aquatic creatures could be used as the ecological equivalent of a canary in a coalmine for assessing inland freshwater lakes and ponds.

Unmasking anthrax for immune destruction

Anthrax-causing bacteria can be engineered to shed their invisibility cloaks, making it easier for the immune system to eradicate it, according to a new study.

Fighting fungal infections with bacteria

A bacterial pathogen can communicate with yeast to block the development of drug-resistant yeast infections, say Irish scientists.

Seeing disease may trigger immune response

Just seeing someone who looks sick is enough to make your immune system work harder, according to a new study in which volunteers looked at pictures of sick people.

Microbes contribute less to climate warming

The physiology of microbes living underground could determine the amount of carbon dioxide emitted from soils on a warmer Earth, according to a study published online this week.

New cell measurement system

Using a sensor that weighs cells with unprecedented precision, researchers have measured the rate at which single cells accumulate mass - a feat that could shed light on how cells control their growth and why those controls fail in cancer...

Combatting vancomycin resisitance

A new study has uncovered for the first time how bacteria recognise and develop resistance to a powerful antibiotic used to treat superbug infections.

Chip checks for oral cancer

The gentle touch of a lesion on the tongue or cheek with a brush can help detect oral cancer with success rates comparable to more invasive techniques, according to preliminary studies.

Cryptococcus' affinity for brains

Highly dangerous Cryptococcus fungi love sugar and will consume it anywhere because it helps them reproduce. In particular, they thrive on a sugar called inositol which is abundant in the human brain and spinal cord.
