Research seeks alternatives for reducing bacteria in fresh produce using nanoengineering
A team of researchers at Wayne State University have been exploring natural, safe and alternative antimicrobials to reduce bacterial contamination. Plant essential oils such as those from thyme, oregano and clove are known to have a strong antimicrobial effect, but currently their use in food protection is limited due to their low solubility in water.

Giant cosmic tsunami wakes up comatose galaxies
A composite image of the ‘Sausage’ merging cluster CIZA J2242.8+5310, made using data from the Subaru and Canada France Hawaii Telescopes (CFHT). The white circles indicate galaxies outside of the cluster, while yellow circles are cluster galaxies, where accelerated star formation is taking place. Green marks regions of radio emission, tracing out shock waves and purple marks the hot gas between the galaxies that emits X-rays. The cluster is one of the most massive in the Universe.

Northwestern scientists develop first liquid nanolaser: Technology could lead to new way of doing 'lab on a chip' medical diagnostics
To understand the concept, imagine a laser pointer whose color can be changed simply by changing the liquid inside it, instead of needing a different laser pointer for every desired color.

Nature: Low-reflection wings make butterflies nearly invisible: Irregular nanostructures on the transparent wing of the glasswing butterfly prevent the reflection of light -- publication in Nature Communications -- researchers plan applications
Contrary to other transparent surfaces, the wings of the glasswing butterfly (Greta Oto) hardly reflect any light. Lenses or displays of mobiles might profit from the investigation of this phenomenon.

Surface matters: Huge reduction of heat conduction observed in flat silicon channels
The different circles represent the studied surfaces of the Si membranes: crystalline, rough, flat with native SiO2, and rough with native SiO2. The right image shows a representative thermal map on the membranes upon a localized thermal excitation used to measure the thermal conductivity.
