Virus detection and identification

PCR-based detection and identification of viruses assumes a known, relatively stable genome.

What women want

A new study from The University of Texas at Austin reveals women's preferences can be influenced by their own attractiveness.

Lung cancer prevention

A small RNA molecule, known as let-7 microRNA (miRNA), substantially reduced cancer growth in multiple mouse models of lung cancer.

Precise 3-D imageing of the human brain

New technology at is enabling researchers to translate the most abstract, complex scientific concepts into clearer, more precise 3-dimensional images.

New ways of disarming the herpes virion

Researchers used mutations of the herpes simplex virus' NS5A phosphoprotein to disrupt virus particle production at an early stage of assembly.

Staph A camouflage

Researchers have uncovered how the bacterium Staphylococcus aureus resists our body's natural defences against infection.

Strengthening T-Cells

When a certain protein was activated in mice, the animals eliminated existing tumours and were protected against developing new ones.

When salmonella kills

Nearly half of all HIV-positive African adults who become infected with Salmonella die from what otherwise would be a seven-day bout of diarrhoea.

Six organs removed

To get to a tumor, a organ transplant specialist said he first had to remove her stomach, pancreas, spleen, liver and small and large intestines.

Is organic productive?

Can organic cropping systems be as productive as conventional systems? The answer is an unqualified, "Yes" and a qualified "Most of the time."

Blood test replacement

One day soon patients may spit in a cup, instead of bracing for a needle prick, when being tested for cancer, heart disease or diabetes.

MRI charts blood volume

A special type of magnetic resonance imaging can depict changes in blood volume in the brain that often precede cancerous transformation of brain tumours.

Ant gut-based drugs

Scientists have discovered two key proteins that guide one of the two groups of pathogenic bacteria to make their hardy outer shells - their defence against the world.

Seeing may be believing

While people do tend to notice objects within their gaze, it is the assumptions they make about their environment that affects their perceptions.

Epilepsy's hub

An increased number of neuron hubs in the epileptic brain may be the root cause for the seizures that characterise the disorder.

Antidepressants link

The risk of diabetes almost doubled for the patients who were using tricyclic antidepressants and selective serotonin re-uptake inhibitors.

Defending corn kernels

Discovery that a specific gene is integral to both fungal invasion of corn and development of a potentially deadly toxin in the kernels may lead to ways to control the pathogen and the poison.

Genome research ethics

A global team of legal, scientific and ethics experts have put forward eight key recommendations to establish guidelines for conducting research.

Numbers not enough

Researchers are not contradicting the theory that it is possible to demonstrate signal transfer in proteins using statistical methods.
