Newly discovered antibody may be body's natural defense against Alzheimer's

...re of the protein when the amyloid was "aged" in a way that allowed soluble aggregates to form. These beta amyloid "oligomers" can grow into insoluble "fibrils" that cluster around brain cells and are a hallmark of Alzheimer's disease. While monomers are produced from birth and appear to be relativel...

Genetic factors are linked to fever following smallpox vaccination

... “Vaccines are the safest and most effective way to prevent a number of very important childhood and adult diseases,” Dr. Stanley remarked. “Our work is designed to identify ways we might make vaccines even more acceptable in the future by discovering ways to further reduce the chance of minor adve...

Could fungal collection hold the key to new life-saving drugs?

...ontain new compounds that can be used to point the way to new drugs for serious diseases.” CABI currently uses its fungal collection, along with the expertise of its scientists to offer a range of services to businesses, including fungal identification, sales, preservations, patenting, training and co...

New findings challenge established views on human genome

...s uncovered many exciting surprises and blazed the way for future efforts to explore the functional landscape of the entire human genome,” said NHGRI Director Francis S. Collins, M.D., Ph.D. “Because of the hard work and keen insights of the ENCODE consortium, the scientific community will need to rethin...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

...s diseases. The approach represents a potential way to overcome hurdles in delivering cargo to the interiors of cells, where they could be used as an alterative technology for gene therapy, said Rashid Bashir, a researcher at Purdue's Birck Nanotechnology Center. The researchers attached nanopartic...

Warning from Asian bees

...lations. Asian bees are known to have found their way into Australian ports at least half a dozen times in the last decade. This time it’s a Javanese strain of the bee and because the latest incursion had lain undiscovered for at least three months, it is unknown how many more swarms might exist and ...

Weizmann Institute scientists develop a general 'control switch' for protein activity

... discovery of insulin’s role in diabetes paved the way for the development of a treatment based on insulin injections. Yet, despite enormous research efforts led by scientists worldwide, the cellular function of numerous proteins is still unknown. To reveal this function, scientists perform various genet...

Researchers discover 'acquired' DNA key to certain bacterial infection

...f acquired genetic material, the bacterium finds a way to get inside the cells and it takes control, not the phagocyte.” Phagocytes are cells that engulf and digest pathogens and cellular debris, and in humans serve as the body’s initial immune response. The researchers did not find a similar isla...

Fat fish put obesity on the hook

...ience University in Portland, OR, have found a new way fish can help eliminate obesity. In a study to be published in the July 2007 print issue of The FASEB Journal, researchers describe the first genetic model of obesity in a fish. Having this model should greatly accelerate the development of new drugs...

Revealed -- Mosquito genes that could be controlling the spread of killer viruses

...and as much as possible about these genes, and the way they interact with specific pathogens, we hope to gain a more complete understanding of the mechanisms by which a pathogen either survives inside the insect body, or is killed by the insect’s defences.” The international research team, led by Impe...
