One of the ways in which cancer cells evade anticancer therapy is by producing a protein that pumps drugs out of the cell before these compounds can exert their cell-killing effects. A research team at Northwestern University has found that biocompatible iron oxide-titanium dioxide nanoparticles can bypass this pump and enable DNA-damaging anticancer drugs to reach the cell nucleus.

Scientists have discovered that a superlattice phase-change film multilayered using germanium-tellurium alloy sub-layers and antimony-tellurium alloy sub-layers with aligned orientation axes has a magnetoresistance effect in excess of 2000% in a temperature range from room temperature to around 150 C.

When a pebble is dropped onto the surface of a pond, a droplet of water bounces up from the surface. The same thing happens when a focussed laser-beam strikes the surface of a thin metal film - the metal can be locally melted by the laser light and it can bounce up from the metal surface as a metallic droplet. Researchers now show that this phenomenon can be used to make nanoscale metallic droplets.

Researchers at Eindhoven University of Technology (TU/e) have succeeded in monitoring and controlling a molecular self-assembly process via different pathways. While it was formerly thought that the molecules form the right structure by themselves, this research shows that the assembly process can follow different pathways yielding different structures; in this case polymer chains with left- and right-handed helical directions.

By shining infrared light on specially designed, gold-filled silicon wafers, scientists at The Methodist Hospital Research Institute have successfully targeted and burned breast cancer cells. If the technology is shown to work in human clinical trials, it could provide patients a non-invasive alternative to surgical ablation, and could be used in conjunction with traditional cancer treatments, such as chemotherapy, to make those treatments more effective.
