Cell discovery strengthens quest for cancer treatments
Fresh insights into how our cells multiply could help scientists develop drugs to treat cancer. Researchers have gained better understanding of the workings of two key proteins that control cell division. This process must be carried out accurately to keep cells healthy, and when it goes out of control, it can lead to cancer.

New findings show how some cells protect themselves against HIV
A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it needs to replicate, according to research published online in Nature Immunology.

New technology to tackle treatment-resistant cancers
Free-flowing cancer cells have been mapped with unprecedented accuracy in the bloodstream of patients with prostate, breast and pancreatic cancer, using a brand new approach, in an attempt to assess and control the disease as it spreads in real time through the body, and solve the problem of predicting response and resistance to therapies.

Warfarin and aspirin are similar in heart failure treatment
In the largest and longest head-to-head comparison of two anti-clotting medications, warfarin and aspirin were similar in preventing deaths and strokes in heart failure patients with normal heart rhythm, according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2012.

Websites advertising cholesterol-lowering drugs of poor quality
A new study published in the journal Pharmacoepidemiology & Drug Safety reveals that internet sites selling prescription statins directly to consumers are widespread, and that most websites advertising statins for sale to the general public contain very poor levels of information relevant to safe use of the medicine and side effects.

Protein structures give disease clues
Using some of the most powerful nuclear magnetic resonance equipment available, researchers at the University of California, Davis, are making discoveries about the shape and structure of biological molecules - potentially leading to new ways to treat or prevent diseases such as breast cancer and Alzheimer's disease.
