Scientists find a way to detect which breast abnormalities may develop into cancer
Scientists at the Royal Liverpool University Hospitals in the UK have found a way of testing whether certain abnormalities in a woman's breast are likely to go on to develop into breast cancer, the 3rd European Breast Cancer Conference in Barcelona heard today (Wednesday 20 March). Armed with information from the test, doctors could then consider... view more... (2002-03-18)

Neuroblastoma expert reviews progress and challenges in fighting difficult pediatric cancer
Childhood cancers are fortunately rare, but among them, neuroblastoma is a special case, accounting for 7 percent of all childhood cancers, but 15 percent of childhood cancer deaths. view more (2007-06-25)
DNA test shows promise for identifying patients with colorectal cancer (p 1283)
Testing for DNA changes in stools might provide a new, accurate, and less invasive way to screen patients for colorectal cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Colorectal cancer is one of the most common cancers in the industrialised world, and early detection might help to reduce the risk of death... view more... (2004-04-14)
Probiotic bacteria at weaning may help alleviate allergy in infants
“Friendly” bacteria (probiotics) given to babies during weaning may help alleviate the symptoms of eczema, suggests research in Gut. view more (2002-06-20)
Identifying the potential for tamoxifen resistance in patients
Tamoxifen is a widely used and highly successful drug in the treatment of breast cancer, though resistance to tamoxifen is still a concern in recurrent disease (affecting 25-35% of patients), since therapy resistant metastatic tumor cells are a major cause of death. view more (2009-06-11)
Why face symmetry is sexy across cultures and species
In humans, faces are an important source of social information. One property of faces that is rapidly noticed is attractiveness. Research has highlighted symmetry and sexual dimorphism (how masculine/feminine a face is) as important variables that determine a face's attractiveness. view more (2008-05-07)

Mini subs to probe odd structures in BC lake
Single person submersibles have been called in to help scientists retrieve samples from a lake in northern British Columbia that may hold vital clues to the history of life on Earth and on other planets. view more (2008-06-17)
Colon Cancer Screening Technique Shows Continued Promise in New Study
Recent clinical trials show that a new colon cancer screening technique created by Northwestern University researchers has a high enough sensitivity that it could potentially be as or more successful than a colonoscopy in screening for colon cancer. view more (2009-06-10)
Prairie soil organic matter shown to be resilient under intensive agriculture
A recent study has confirmed that although there was a large reduction of organic carbon and total nitrogen pools when prairies were first cultivated and drained, there has been no consistent pattern in these organic matter pools during the period of synthetic fertilizer use, that is, from 1957-2002. view more (2009-01-16)
10 Million Euro Technology Project Makes Europe a leader in Biocrystallography
A project to create a common platform throughout Europe for researchers working in the field of 'biological crystallography' is underway thanks to a grant of 10 million euros from the EU's 6th Framework Programme (FP6). view more (2005-02-08)
UWE develops detectors for oestrogen in river water
Small quantities of oestrogens, which are female hormones, are excreted from the body and thus enter the sewage system. Although these chemicals seem to be largely removed in sewage treatment, it seems that minute quantities remain and thus can enter rivers to which treated sewage is discharged. These very low levels of oestrogens have been... view more... (2001-08-14)

Component of red wine quells inflammation in chronic inflammatory lung disease (COPD)
A component of red wine, resveratrol, seems to damp down the inflammatory process in the progressive lung disease COPD, finds a small study in Thorax. So effective was resveratrol in laboratory tests that the authors suggest that the compound could be developed to treat the disease. COPD (chronic obstructive pulmonary disease) is irreversible and... view more... (2003-10-24)
Silicon May Have Been The Key To Start Of Life On Earth
A scientist at the University of Sheffield has discovered that silicon may have been key to the establishment of life on earth. Until now it has generally been thought that bacteria do not interact with silicon, but Dr Milton Wainwright and his team at the University's Department of Molecular Biology and Biotechnology, has found that this is not... view more...
