Navarre researcher, Jaione Valle Turrillas, has identified two genes that could help as targets for pharmaceutical drugs that fight the Staphylococcus aureus “one of the bacteria which causes most infections in medical implants”. The results of her research have been published in her PhD thesis, "The role of the global regulators SarA and õB in Staphylococcus aureus biofilm formation", defended at the Public University of Navarre.
Bacterias a thousand time more resistant
The bacteria Staphylococcus aureus is one of those which are associated with greater frequency of infections in implants carried out in hospitals. Usually, the bacteria adheres to the surface of the implant, “where microorganism communities are formed that grow on being absorbed into a matrix of polysaccharides, commonly known as biofilm”, according to Jaione Valle.

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...
