Patient access schemes for high-cost cancer medicines: Good in theory, difficult in practice
Patient access schemes -- created by the pharmaceutical industry to allow access to expensive cancer drugs -- can be fraught with administrative problems, meaning that money does not reach the parts of the UK National Health Service that it should, if at all.

No difference in survival between leukaemia patients 10 years after undergoing stem-cell or marrow transplant
Patients transplanted with peripheral blood stem cells have no difference in survival compared with patients given bone marrow after 10 years, according to the largest randomized study comparing the effect of type of transplant on survival, published online first in the Lancet Oncology.

Gene function discovery: Guilt by association
Scientists have created a new computational model that can be used to predict gene function of uncharacterized plant genes with unprecedented speed and accuracy.

New technology aims to repair the after-effects of gum disease
Advances in tissue engineering are offering the promise of being able to restore lost bone and gum tissue following periodontal disease.

Cells send dirty laundry home to mom
Understanding how aged and damaged mother cells manage to form new and undamaged daughter cells is one of the toughest riddles of aging, but scientists now know how yeast cells do it.

Dogs may provide an excellent model for understanding human complex diseases
In the new Swedish-Finnish study, published in Nature Genetics, the researchers identified five loci that predispose to an SLE-related disease in Nova Scotia duck tolling retrievers.

Seeing the brain hear reveals surprises about how sound is processed
Neurobiologists at the University of Maryland have discovered information about how the brain processes sound that challenges previous understandings of the auditory cortex.

WHO pneumonia expert recognized for efforts to ensure children receive life-saving vaccines
WHO pneumonia expert Dr. Thomas Cherian will be honored by a group of the world's leading infectious disease experts today for his pivotal work to accelerate access to vaccines preventing pneumococcal disease, the world's leading vaccine-preventable killer of children under age five.

Novel studies of decomposition shed new light on our earliest fossil ancestry
Decaying corpses are usually the domain of forensic scientists, but palaeontologists have discovered that studying rotting fish sheds new light on our earliest ancestry.

Uncritical IT implementation in Swedish schools
Thomas Karlsohn at the University of Gothenburg; Sweden, has explored the IT bubble in the Swedish school system and the rhetoric used in the education trade press, and his conclusion is clear: the introduction of IT in Swedish schools could have been scrutinized better.

Dog studies reveal strong risk factors for SLE
Researchers at Uppsala University and the Swedish University of Agricultural Sciences have found several genes that lead to increased risk for an SLE-like autoimmune disorder in dogs.

HIV researchers solve key puzzle after 20 years of trying
Researchers have made a breakthrough in HIV research that had eluded scientists for over 20 years, potentially leading to better treatments for HIV, in a study published today in the journal Nature.
