Quantum dot nanodevice that can detect and image apoptosis

Aiming to help researchers get a better handle on how - and if - anticancer agents are triggering cell death, investigators at the University of Twente in The Netherlands have developed a quantum dot nanodevice that can detect and image apoptosis, also known as programmed cell death.

Researchers study cells whose membranes have been opened by ultrasound

Researchers have shown how ultrasound energy can briefly "open a door" in the protective outer membranes of living cells to allow entry of drugs and other therapeutic molecules – and how the cells themselves can then quickly close the door.

Mitochondrial DNA sequencing tool updated

High-tech laboratory tools, like computers, are often updated publicly as their analytical capabilities expand. In the September issue of the Journal of Molecular Diagnostics, NIH grantees report they have developed a second generation "lab on a silicon chip" called the MitoChip v2.0 that for the first time rapidly and reliably sequences all mitochondrial DNA.

Genotoxic bacteria in the digestive tract

Escherichia coli is a commensal bacterium, which lives peacefully in our digestive tract. However, certain strains are pathogenic and are frequently incriminated in a broad spectrum of infections, affecting both farmed animals and humans (diarrhoea, urinary tract infections, food poisoning, septicaemia, neonatal meningitis, etc.).

DNA overwinds when stretched

Most of us are familiar with the winding staircase image of DNA, the repository of a biological cell's genetic information. But few of us realize just how tightly that famous double helix is wound.
