Moon Dust Would Give Astronauts Lunar Hay Fever

Astronauts of the future spending long periods of time on the moon could suffer from bronchitis and other health problems by inhaling tiny particles of lunar dust, study indicates. Simulated lunar soil is toxic to human lung and mouse brain cells. Up to 90 percent of human lung cells and mouse neurons died when exposed [...]

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 [...]

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 [...]

A cellular pump known to move drugs like antibiotics out of E. coli bacteria has the potential to bring them in as well, researchers in the University of Wisconsin-Madison Department of Biochemistry have discovered. The finding could revise almost 50 years of thinking about how these types of transporters function in the cell. Cells must [...]

Laser Triggered Nanoshells Deliver Drugs Inside Tumors

Researchers have developed a method for delivering cancer-killing drugs inside tumors with gold nanoparticles they can activate remotely using a laser. The researchers employed gold nanoshells to deliver toxic doses of two drugs — lapatinib and docetaxel — inside breast cancer cells, showing they could use a laser to remotely trigger the particles to release [...]
