Scientists can now differentiate between healthy cells and cancer cells - One of the current handicaps of cancer treatments is the difficulty of aiming these treatments at destroying malignant cells without killing healthy cells in the process. But a new study by McMaster University researchers has provided insight into how scientists might develop therapies and drugs that more carefully target cancer, while sparing normal healthy cells ...

New insight into aggressive childhood cancer - A new study reveals critical molecular mechanisms associated with the development and progression of human neuroblastoma, the most common cancer in young children. The research, published by Cell Press in the January 6th issue of the journal Cancer Cell, may lead to development of future strategies for treatment of this aggressive and unpredictable cancer. ...

Aquaculture's growth seen as continuing - Aquaculture production of seafood will probably remain the most rapidly increasing food production system worldwide through 2025, according to an assessment published in the January 2009 issue of BioScience. The assessment, by James S. Diana of the University of Michigan at Ann Arbor, notes that despite well-publicized concerns about some harmful effects of aquaculture, the technique may, when practiced well, be no more damaging to biodiversity than other food production systems. Moreover, it may be the only way to supply growing demand for seafood as the human population increases. ...

Dormant cancer cells rely on cellular self-cannibalization to survive - A single tumor-suppressing gene is a key to understanding, and perhaps killing, dormant ovarian cancer cells that persist after initial treatment only to reawaken years later, researchers at The University of Texas M. D. Anderson Cancer Center report in the December Journal of Clinical Investigation. ...

Study shows that the societal, economic burden of insomnia is high - A study in the Jan. 1 issue of the journal Sleep indicates that the indirect costs of untreated insomnia are significantly greater than the direct costs associated with its treatment. The study estimates that the total annual cost of insomnia in the province of Quebec is 6.5 billion Canadian dollars, representing about one percent of the province's $228.5 billion in gross domestic product for 2002. ...

Few DNA repair genes maintain association with cancer in field synopsis - Variants of numerous DNA repair genes initially appeared to be statistically significantly associated with cancer risk in epidemiological studies. When the data from individual studies are pooled, however, few DNA repair gene variants appear truly associated with increased cancer risk, according to a field synopsis published in the December 30 online issue of the Journal of the National Cancer Institute. ...

Facial expressions of emotion are innate, not learned, says new study - Facial expressions of emotion are hardwired into our genes, according to a study published today in the Journal of Personality and Social Psychology. The research suggests that facial expressions of emotion are innate rather than a product of cultural learning. The study is the first of its kind to demonstrate that sighted and blind individuals use the same facial expressions, producing the same facial muscle movements in response to specific emotional stimuli. ...

Flowering plants speed post-surgery recovery - Contact with nature has long been suspected to increase positive feelings, reduce stress, and provide distraction from the pain associated with recovery from surgery. Now, research has confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery. ...
