Canadian researchers have identified a new protein in the progression of breast cancer. According to a recent study from the Université de Montréal and the University of Alberta, published in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours. Targeting this protein with drug therapy may provide hope to women with breast cancer.

Adelaide researchers have made a world breakthrough in treating premature babies at risk of developmental disorders.

New data released today by the Wildlife Conservation Society and Malaysia's Department of Wildlife and National Parks (DWNP) reveals that a population of endangered Asian elephants living in a Malaysian park may be the largest in Southeast Asia.

A tug-of-war between the two sides of the brain causes it to become asymmetrical, according to research published today in the journal Neuron. Asymmetry in the brain is thought to be important to enable the two hemispheres to specialise and operate more efficiently.

Scientists at Albert Einstein College of Medicine of Yeshiva University have identified a small intracellular protein that helps cells commit suicide. The finding, reported as the "paper of the week" in the January 16th print issue of the Journal of Biological Chemistry, could lead to drugs for combating cancer and other diseases characterized by overproduction of cells. The research was led by the late Dennis Shields, Ph.D., a professor in Einstein's Department of Developmental and Molecular Biology for 30 years, who died unexpectedly in December.

Scientists at St. Jude Children's Research Hospital have teased apart the biological details distinguishing two related neurological diseases—ataxia telangiectasia-like disease (ATLD) and Nijmegen breakage syndrome (NBS).
