New biomarker for HIV

An increase in the CD163+/CD16+ monocyte subset could be a biomarker for the progression of HIV disease, according to researchers.

Brain development

Scientists have identified a gene that, in mice, is critical for these stem cells to divide correctly. Without it, they fail and die.

Folate scores big

The vitamin B chemical, folate, found in leafy green vegetables, beans and nuts has now been shown to blunt the damaging effects of heart attack.

Staph A camouflage

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

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.

Virus detection and identification

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

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.

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.

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.

Norwalk virus' weakness

An international team has determined the detailed structure of the enzyme the Norwalk virus uses to make copies of its genetic code in order to replicate itself.

Nogo receptor boosts synapses

New findings about a protein called the nogo receptor are offering fresh ways to think about keeping the brain sharp, by boosting synapse signals.

Awakening stem cells

Scientists have discovered what chemical in the eye triggers the dormant capacity of certain non-neuronal cells to transform into progenitor cells.

Parasitic worm disease

A research team has identified chemical compounds that hold promise as potential therapies for schistosomiasis, a parasitic disease that afflicts people worldwide.

Inflammatory diseases

Investigators have identified a new mechanism involved in the pathogenesis of inflammatory diseases such as rheumatoid arthritis.

Promise in HIV switch

If the battle against HIV, the virus that causes AIDS, is a chess match, then new research gives new insight into one of the virus' most important moves.

New patent system

Biotechnology discoveries are at risk of being unduly hindered or taken hostage by private corporations unless patent systems are brought into the 21st century.

New haemoglobin type

Scientists at the University of Bonn have discovered a new rare type of haemoglobin distorts the level of oxygen measured.

Emerging disease hotstops

Scientists say the next major disease could occur in any of a number of developing countries concentrated along the equator.

Microbial profiles of ecosystems

A new study provides the first inventories of microbial capabilities in nine very different types of ecosystems, ranging from coral reefs to deep mines.
