Nearly one-third of cancer studies published in high-impact journals disclosed a conflict of interest, according to a new study from researchers at the University of Michigan Comprehensive Cancer Center.

Scientists who study cancer may be prone to drawing simplistic conclusions from the powerful molecular tools now available because they don’t appreciate how complex the data is that is being generated, said a team of Georgetown University Medical Center (GUMC) researchers in the January issue of Nature Reviews Cancer.

A report released today confirms women have a very high chance of surviving breast cancer if it is detected early. The study has found the five-year survival rate for women whose cancer was less than one centimetre in size was almost as high as for women without breast cancer at all.

MIT researchers have developed a new way to study the function of microRNA, tiny strands of genetic material that help regulate at least 25 percent of a cell's genes.

Scientists have captured on video the intracellular version of a postal delivery service. Reporting in the journal Biochemical and Biophysical Research Communications (BBRC), bioengineering researchers at UC San Diego published videos of a key message-carrying protein called paxillin moving abruptly from hubs of communication and transportation activity on the cell surface toward the nucleus. Paxillin was labeled with a red fluorescence marker to make it stand out in live cells.

Hormone Replacement Therapy (HRT), the menopause treatment previously linked to breast cancer, may now also increase the risk of ovarian cancer. A British study has found those on HRT were more than 20 per cent more likely to develop ovarian cancer.

What happens when a 68 million-year-old Tyrannosaurus Rex meets 21st century medical science? A North Carolina State University researcher and her colleagues at Harvard Medical School and Beth Israel Deaconess Medical Center found out when they confirmed the existence of protein in soft tissue recovered from the bone of a 68 million-year-old T. rex.
