Detecting extraterrestrial life through nanoscale vibrations

Scientists have developed an extremely sensitive yet simple motion detector that can be built easily by adapting already-existent technology. The system has proven accurate with detecting bacteria, yeast, and even cancer cells, and is considered for the rapid testing of drugs and even the detection of extraterrestrial life.

Gummy bears under antiparticle fire

Gelatin is used in the pharmaceutical industry to encapsulate active agents. It protects against oxidation and overly quick release. Nanopores in the material have a significant influence on this, yet they are difficult to investigate. In experiments on gummy bears, researchers have now transferred a methodology to determine the free volume of gelatin preparations.

Magnetic vortices: Controlling core switching in Pac-man disks

Magnetic vortices in thin films can encode information in the perpendicular magnetization pointing up or down relative to the vortex core. These binary states could be useful for non-volatile data storage devices such as RAM memories, but the switching between them must be fast and energy-efficient.

How electrons split: New evidence of exotic behaviors

In certain materials where the electrons are constrained in a quasi one-dimensional world, they appear to split into a magnet and an electrical charge, which can move freely and independently of each other. A longstanding question has been whether or not similar phenomenon can happen in more than one dimension. Researchers have uncovered new evidence showing that this can happen in quasi two-dimensional magnetic materials.
