Key protein that may cause cancer cell death identified
— 17:20 GMT | HealthResearchers at ASTAR's Institute of Molecular and Cell Biology (IMCB) have become the first to discover and characterise a human protein called Bax-beta (Bax-beta), which can potentially cause the death of cancer cells and lead to new approaches in cancer treatment. The finding is published in the 16 January report of Molecular Cell…
Postnatal depression can possibly be prevented drug-free
— 17:20 GMT | HealthA heart-to-heart chat with a peer has proven an effective way to prevent postnatal depression in high risk women, cutting the risk of depression by 50%, according to a University of Toronto nursing study published in BMJ Online…
Pre-emptive treatment helped curtail skin toxicity with panitumumab
— 16:46 GMT | HealthWith a pre-emptive, prophylactic skin regimen, patients who receive panitumumab for treatment of metastatic colorectal cancer may be able to avoid some of the skin-associated toxicities, according to data presented at the 2009 American Society of Clinical Oncology Gastrointestinal Cancers Symposium in San Francisco…
Study may give hope that ivory-billed woodpeckers still around
— 16:46 GMT | BiologyUntil credible sightings popped up three years ago, the scientific world was in agreement that ivory-billed woodpeckers had gone the way of the dodo. A new study conducted by University of Georgia researchers reveals that the ivory-billed woodpecker could have persisted if as few as five mated pairs survived the extensive habitat loss during the early 1900's. A new paper published in the online journal Avian Conservation and Ecology by researchers at the Warnell School of Forestry and Natural Resources adds another angle to the ongoing debate about modern existence of the birds…
Slight changes in climate may trigger abrupt ecosystem responses
— 16:46 GMT | EnvironmentSome of these responses, including insect outbreaks, wildfire, and forest dieback, may adversely affect people as well as ecosystems and their plants and animals…
Neurones show sex-dependent changes during starvation
— 16:46 GMT | HealthWhen it comes to keeping brains alive, it seems nature has deemed that females are more valuable then males. As reported in this weeks' JBC, researchers found that nutrient deprivation of neurones produced sex-dependent effects. Male neurones more readily withered up and died, while female neurones did their best to conserve energy and stay alive…
Dartmouth researchers identify potential cancer target
— 16:46 GMT | HealthDartmouth Medical School researchers have found two proteins that work in concert to ensure proper chromosome segregation during cell division. Their study is in the January 2009 issue of the journal Nature Cell Biology…
Why you can't hurry love
— 16:46 GMT | BiologyScientists have developed a mathematical model of the mating game to help explain why courtship is often protracted. The study, by researchers at UCL (University College London), University of Warwick and LSE (London School of Economics and Political Science), shows that extended courtship enables a male to signal his suitability to a female and enables the female to screen out the male if he is unsuitable as a mate…
Canada-US scientists discover gene responsible for brain's ageing
— 16:46 GMT | HealthWill scientists one day be able to slow the ageing of the brain and prevent diseases such as Alzheimer's and Parkinson's? Absolutely - once the genetic coding associated with neuronal degeneration has been unravelled…
The heart disease mutation carried by 60 million
— 16:46 GMT | HealthHeart disease is the number one killer in the world and India carries more than its share of this burden. Moreover, the problem is set to rise: it is predicted that by 2010 India's population will suffer approximately 60% of the world's heart disease. Today, an international team of 25 scientists from four countries provides a clue to why this is so: 1% of the world's population carries a mutation almost guaranteed to lead to heart problems and most of these come from the Indian subcontinent, where the mutation reaches a frequency of 4%…
