Stopping bacteria from talking to each other could help prevent serious infections say scientists from Aberdeen, in new research presented Monday, 06 September 2004 at the Society for General Microbiology’s 155th Meeting at Trinity College Dublin.
“It is war out there. Bacteria need to wait until there are enough of them to attack us, otherwise they just get beaten off by our skin, the antibodies which patrol our blood, and our other defences,” says Professor Andrew Porter from Aberdeen University spin-out company Haptogen. “They use tiny molecules called haptens to talk to each other, letting each other know how many of them there are, much in the same way that we can smell things to sense what is going on in the world around us.”
“If we can block the actions of the haptens then we can fool the bacteria into thinking that there aren’t enough of them to attack us,” says Prof Porter. “The problem is that haptens are such tiny molecules that they don’t trigger our normal immune defences - they are so small they are invisible to our early warning radar.”

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...
