Microcantilevers are masters of measurement

Rice University researcher Sibani Lisa Biswal and Kai-Wei Liu, a graduate student in Biswal's lab who recently earned her doctorate at Rice, used microcantilevers as ultrasensitive measuring devices to study how lipid bilayers interact with surfactants.

Hart oder weich - beides zugleich: Neues Nanomaterial wechselt Eigenschaft nach Bedarf

Das hat die Welt noch nicht gesehen: Ein Werkstoff, der quasi auf Knopfdruck seine Festigkeit aendert. Dieser Wandel in Sekundenschnelle kann durch Aenderungen der Elektronenstruktur eines Materials erreicht und so zum Beispiel aus einem festen und sproeden Stoff ein weicher und formbarer werden. Den entscheidenden Impuls liefern elektrische Signale, Clou dieser sensationellen Entwicklung.

Microscopic worms could help open up travel into deep space

A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.

An alternative to antibiotics

Antibiotics are among the greatest achievements of medical science. But lately the former multi-purpose weapon fails in the battle against infectious diseases. Bacteria are increasingly developing resistance to antibiotics. Researchers have now found a therapeutic equivalent which could replace penicillin and related phamaceuticals.

The fine art of etching

They see more than the naked eye and could make traffic safer: miniaturized thermal imaging sensors. But they are difficult to manufacture on a commercial scale. Researchers have now developed a new system. On it, special micro-electromechanical systems can be produced - with the correct etching technique.

Quantum knowledge cools computers

Research without supercomputers is unimaginable nowadays. However, they increasingly represent an energy problem. Every single computer operation, especially deleting data, converts electrical energy into heat. For this reason, the latest research results by a team of physicists from Switzerland, England and Singapore deserve careful attention: under certain conditions, cold is generated instead of heat when deleting data. The only condition is that the content of the memory must be known "more than completely" during the deletion process. This is possible provided the so-called quantum-mechanical entanglement is included, since such entanglement carries more information than a classical copy of the data.
