Attacking Cancer Cells with Hydrogel Nanoparticles

(PhysOrg.com) -- One of the difficulties of fighting cancer is that drugs often hit other non-cancerous cells, causing patients to get sick. But what if researchers could sneak cancer-fighting particles into just the cancer ...

Human cell death captured for first time

Scientists based at the La Trobe Institute of Molecular Science have discovered that some molecules which are central to the body's defence and immune system are ejected from inside the decomposing cell to form long beaded ...

Nanotechnology: A dead end for plant cells?

Using particles that are 1/100,000 the width of a human hair to deliver drugs to cells or assist plants in fighting off pests may sound like something out of a science fiction movie, but these scenarios may be a common occurrence ...

Deadly combination: New direct trigger for cell death discovered

Scientists led by Professor Ana J. Garcia-Saez at the CECAD Cluster of Excellence for Aging Research at the University of Cologne have shown that apoptosis, the programmed cell death, involves a direct physical interplay ...
