Hybrid Nano-probe Can Detect Live Cancer Cells

A new hybrid nano-probe that could lead to noninvasive detection and treatment of cancer at the level of a single cell has been developed by a University of Southern California scientist. Fabien Pinaud, assistant professor of biological sciences, chemistry and physics and astronomy at USC Dornsife, created a method for amplifying a biochemical signal on the surface of cancer cells. The new technique binds and assembles gold nanoparticles in living cells using two fragments of a fluorescent protein as “molecular glue. [Read More]

Programmed Nanorobots Seek And Destroy Cancer Tumors

Nanorobots have been successfully programmed to shrink tumors by cutting off their blood supply. This major advancement came from Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences. The demonstration of the technology, the first-of-its-kind study in mammals, used breast cancer, melanoma, ovarian and lung cancer mouse models. said Hao Yan, director of the ASU Biodesign Institute’s Center for Molecular Design and Biomimetics and the Milton Glick Professor in the School of Molecular Sciences.

Exercise In Teen Years Lowers Cancer Risk In Adult Women

Engaging in physical exercise as a teenager can help to lower the risk of death due to cancer and other diseases in later life, researchers recently found. Clarfying long-term impacts of modifiable lifestyle factors like exercise in adolescence is of key importance, and could have significant public health implications for disease prevention over the course of life, said lead author Sarah J. Nechuta. Nechuta and her colleagues analyzed data from the Shanghai Women’s Health Study, a large, population-based prospective cohort study of about 75,000 women ages 40 to 70, from Shanghai, China, led by Wei Zheng, MD, PhD, at the Vanderbilt Epidemiology Center.
