Deciphering gold nanoclusters

Researchers have described the principles behind the stability and electronic properties of gold nanoclusters, confirming the divide and protect bonding structure.



Exhausted B cells fail to fight HIV

Individuals who had high levels of HIV in their blood had lots of B cells, but they failed to replicate normally or to produce high-quality antibodies.



Tweaking quantum forces

Physicists have discovered that the Casmir force can be reduced by altering the surface of metal plates, a discovery that could prove useful as microelectrochemical systems.



Children's food's empty benefits

Nine out of ten regular food items aimed specifically at children have a poor nutritional content - because of high levels of sugar, fat or sodium - according to a detailed study of 367 products.



Cellular decision on the computer

Scientists have simulated how cells decide whether or not to migrate and were able to predict the molecular targets within a cell that needs to be targeted for the process to occur.



Cleaner hydrogen generation

Utilising the entire spectrum of the sun's energy, water, and nanotube diodes, scientists have produced a in inexpensive and green hydrogen.



Tumour-inhibiting protein

A tumour-inhibiting protein called angiocidin may play a role in a new leukaemia treatment, according to Temple University researchers.



Stomach bug protection for kids

H. pylori, a long-time microbial inhabitant of the human stomach, may protect children from developing asthma, according to a new study among more than 7,000 subjects.



Cancer immune response findings

Researchers conducting a clinical trial of a dendritic cell vaccine designed to fight glioblastoma multiforme have found a correlation between the two.



Common genetic history

Researchers have established an identical mechanism of genetic imprinting, a process involved in marsupial and human foetal development, which evolved 150 million years ago.



Vitamin A incites cancer growth

Vitamin A has been found to promote cancer by turning on genes that cause stem cells embedded in a tumour to transform into endothelial cells that link to the body's blood supply.



Shooting for HIV's weakness

Scientists believe they have discovered a weak spot hidden in HIV's envelope protein, gp120, and believe their results can help develop a preventative vaccine.



Gene signatures for scleroderma

Distinct genetic profiles can discern different groups of patients with scleroderma, a vexing autoimmune disease in which the body turns against itself.



Mind-body connection mechanism discovered

The stress hormone cortisol suppresses immune cells' ability to activate their telomerase, possibly explaining why the cells of persons under chronic stress have shorter telomeres.



Dragon a bird flu killer

Researchers have crystallised and characterised the structure of one of the most important protein complexes of the H5N1 virus, the most common strain of bird flu.




Vaccinating against avian flu

New evidence suggests that a booster vaccination against H5N1 avian influenza given years after initial vaccination with a different strain may prove useful in controlling a potential future pandemic.



Differentiating between ulcers

Multidetector CT using virtual gastroscopy and post contrast enhanced multiplanar reformation images can be useful in differentiating between malignant and benign gastric ulcers.



Circadian rhythms and health

Exposure to irregular patterns of light and darkness can cause the human circadian system to fall out of synchrony with the 24-hour solar day, negatively affecting human health.



Cancer fighting nanoparticles

Scientists have developed a potential new treatment against cancer that attaches magnetic nanoparticles to cancer cells, allowing them to be captured and carried out of the body.



Innate HIV resistance genetic

The simultaneous expression of certain versions of two specific genes called KIR3DL1 and HLA-B*57 is thought to be at the root of some cases of this innate resistance to HIV infection.
