Microbial evolution

A mathematical approach for analysing a protein simultaneously in a set of ecologically distinct species to identify occurrences of natural selection has been developed.

Multiple sclerosis symptoms

A bodysuit that heats or cools a patient, combined with painless measurements of eye movements, helps to study the link between body temperature and MS symptoms.

Fighting cervical cancer

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

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.
