The journal Endocrine-Related Cancer today publishes work showing that scientists from the Clinical Proteomics Program of the US National Cancer Institute (NCI) have discovered a test that was 100% effective for detecting early ovarian cancer in their study.
The study describes the use of a high-resolution mass spectrometer to measure patterns of protein markers in a small sample of blood. The mass spectrometer measured slight differences in the weights between normal and cancerous proteins, enabling the researchers to identify the cells that would lead to cancer. The results of the trial revealed 100 percent sensitivity and 100 percent specificity for the detection of ovarian cancer, including the correct classification of all stage I ovarian cancer cases (where the cancer is still confined to the ovaries).
There are about 6,800 new cases of ovarian cancer each year in the UK, making it the fourth most common cancer among British women*.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
