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.

Crawling the Web: Open Access

Everyday, Scientist Live turns its eyes to the Web around it and highlights news and research across the Internet. Today we look take an extended look at the Open Access debate as well as establishing order in a bacterial cell culture.

Active, sedentary behaviour genetic

Recent mouse model studies indicate that genetics may play a role in influencing whether an animal exhibits active or sedentary behaviour.

Lending a hand

Scientists have compiled guidelines to help other researchers design, develop, and manage next-generation databases of biological parts.

HIV trial hits snag

The National Institute of Allergy and infections Diseases announced that it will not conduct the HIV vaccine study known as PAVE 100.

Schizophrenia, bipolar disorder linked

A new study sought to analyse the patterns of gene expression in the brains of individuals diagnosed with schizophrenia or bipolar disorders.

Protein protects against eye disease

Scientists have identified the protein responsible for transporting nutrients to the eye that are believed to protect against the development of age-related macular degeneration.

Allergies, asthma tied to cell

NYU research shows that Foxp3-directed regulatory T cells (Treg) are produced in the mucosal tissue and remain there to prevent allergic reactions.

HIV destroys immune system quickly

New research into the earliest events occurring immediately upon infection with HIV-I shows that the virus deals a stunning blow to the immune system earlier than was previously understood.

Crawling the Web: Protein interactions

Everyday, Scientist Live turns its eyes to the Web around it and highlights news and research across the Internet. Today we look take an extended look at protein-protein interaction networks.
