New discovery, immune cells confront viruses just inside of the lymph node

Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. An improved understanding of how the immune system operates during a viral infection is critical to designing successful anti-virus vaccines.

New Parkinson's disease research points to serotonin

For most people with Parkinson's disease, the only relief from the tremors, rigidity and impaired movement associated with the progressive loss of their motor skills is a drug called L-DOPA. But as the disease progresses, L-DOPA can cause prominent side effects that counteract its effectiveness.

Researchers examine immune cells where HIV can lie dormant, possible treatments

Researchers have determined how HIV is able to lie dormant in certain immune system cells and prevent the cells from self-destructing, according to a study published Thursday online in the journal Retrovirology, the AP/Google.com reports.

New research shows that people with blue eyes have a single, common ancestor

A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today.

Study looks at safe dosages of the isotope astatine-211 for brain tumors

In a study to determine safe dosages of the isotope astatine-211 for patients with recurring brain tumors, researchers were pleasantly surprised to find that not only was the isotope's potency sufficient to kill residual cancer cells without damaging sensitive healthy brain cells, but the patients experienced longer survival rates.

March of Dimes works to eliminate racial gaps in infant health

In recognition of Black History Month, the March of Dimes is drawing attention to the tremendous gap in premature birth and infant mortality rates that disproportionately affect black women in the United States and to the programs and research designed to reduce -- and one day eliminate -- these disparities.

Onchocerciasis parasite shows signs of resistance

Onchocerciasis is an infection caused by Onchocerca volvulus, a parasite nematode worm transmitted to humans by a species of black fly of the Simulium genus whose larvae develop in fast-flowing rivers.

Body fat protein adiponectin plays role in tumour growth

Scientists have discovered how low levels of a protein hormone found in body fat, plays a crucial role in tumour growth and spread. Their findings are published in a paper in the British Journal of Cancer.

Why your fertility cells must have 'radio silence'

Researchers in Kobe, Japan, and Montreal, Canada, have uncovered a previously unknown mechanism which causes embryonic germ cells which later develop into sperm or ova to go through a period of "transcriptional silence," during which information from the cell's DNA cannot be copied.

Virtual human in HIV drug simulation

The combined supercomputing power of the UK and US 'national grids' has enabled UCL (University College London) scientists to simulate the efficacy of an HIV drug in blocking a key protein used by the lethal virus.

Dairy-free diets may put boys with autism at risk for thin bones

Results of an early study suggest that dairy-free diets and unconventional food preferences could put boys with autism and autism spectrum disorder (ASD) at higher than normal risk for thinner, less dense bones when compared to a group of boys the same age who do not have autism.
