A new molecule designed by University of Adelaide researchers shows great promise for future treatment of many cancers. The new molecule successfully targets a protein that plays a major role in the growth of most cancers. This protein target is called proliferating cell nuclear antigen (PCNA), otherwise known as the […]

The sex of a baby controls the level of small molecules known as metabolites in the pregnant mother’s blood, which may explain why risks of some diseases in pregnancy vary depending whether the mother is carrying a boy or a girl, according to new research from the University of Cambridge. […]

A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer’s growth and spread, University of Illinois researchers report in a new study in mice. The molecules, called endocannabinoids, are made naturally by the body and have similar properties to cannabinoids found in marijuana – but […]

Recent studies show that 40 percent of Americans over the age of 85 have Alzheimer's disease, and that the disease begins 10 to 20 years before people show up at the doctor's office with memory problems. One major problem with understanding Alzheimer’s is not being able to clearly see why […]

What if cancer cells could be re-engineered to turn against their own kind? A new study led by Harvard Medical School researchers at Brigham and Women’s Hospital leverages the power of gene editing to take a critical step toward using cancer cells to kill cancer. The team reports promising results […]

Follow-up imaging for women with non-metastatic breast cancer varies widely across the country, according to a new study led by researchers at UC San Francisco. Some patients go without the annual mammograms that experts recommend, while others with the same cancer diagnosis receive full-body scans that expose them to significant […]

New research on human papillomavirus (HPV) testing drew the same reaction from Drs. Rachel Winer and Constance Mao: It’s about time. The UW Medicine researchers responded to a decade-long study reported by two Canadian universities. It showed that HPV screening is more accurate at detecting cervical pre-cancers than the long-established Pap smear. Both doctors hope this will […]
