The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease.

Buckyballs squeeze hydrogen

Material scientists have discovered that buckyballs are so strong they can hold volumes of hydrogen nearly as dense as those at the centre of Jupiter.

Brain imaging study

Researchers have conducted the first-ever brain imaging study that directly contrasts two different techniques for emotion regulation.

Designer enzyme protection

Designer enzymes will have applications for defence against biological warfare, by deactivating pathogenic biological agents.

Assessing public health preparedness

Since 2001, state and local health departments in the United States (US) have accelerated efforts to prepare for high-impact public health emergencies.

Genotyping of Bacillus anthracis and Yersinia pestis

Anthrax and plague bacteria are etiological agents for worldwide zoonotic diseases and are considered among the most feared potential bioterror agents.

Virus detection and identification

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

What women want

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.

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.
