Using unique nanoparticles that convert laser light into useful information, Rice University scientists have created the world’s first nano-sized pH meter. The discovery, which appears online this week in the journal Nano Letters, presents biologists with the first potential means of measuring accurate pH changes over a wide pH range in real-time inside living tissue and cells.

The University of Leicester is leading a three-nation consortium in a ‘fantastic voyage’ to explore empty space — with potential benefits that have only been explored in the realms of science fiction. The study aims to delve into a ‘void’ or empty space in which atoms move, which has a large intrinsic energy density known as zero-point energy.

An ancient avenue for producing cellular energy, the glycolytic pathway, could provide a surprisingly rich target for anti-cancer therapies. A team of Harvard Medical School (HMS) researchers knocked down one of the pathway’s enzymes, LDHA, in a variety of fast-growing breast cancer cells, effectively shutting down glycolysis, and implanted the cells in mice.

A team of scientists led by Professor Nick Dixon at the Research School of Chemistry at The Australian National University have cracked one of the great DNA mysteries. For more than 20 years scientists have tried in vain to understand the last step in the copying of DNA in cells that are about to divide.
