Gel-filled gemstones make a better breathalyzer

To gauge whether suspects involved in accidents or routine traffic stops have been driving drunk, police officers pair field sobriety tests with breathalyzers, which signal the presence of alcohol in the breath. Most breathalyzers are expensive and unable to test for precise concentrations of alcohol. Offering a better solution, Italian researchers have developed a novel idea for an inexpensive, portable breathalyzer whose color would change from green to red with higher alcohol concentrations.

Cells prefer nanodiscs over nanorods

For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.

Cell-detection system promising for medical research, diagnostics

Researchers are developing a system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient's blood, an advance that could help medical doctors diagnose cancer earlier than now possible and monitor how well a patient is responding to therapy.
