Nanomaterials are rough on microbes such as bacteria. They actually puncture the cell walls of the single-cell microbes, causing leaks and ultimately death. Put that on a cloth and you could have an effective, chemical-free disinfecting wipe.

Researchers designed a polymer known as a liquid crystal elastomer that can be 'programmed' to both twist and bend in the presence of light. Especially in the field of soft robotics, this is essential for building devices that exhibit controllable, dynamic behavior without the need for complex electronic components.

Biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.

Researchers have captured an atomic-level high-definition image of a protein and the small molecule that binds to it. Both have been implicated in conditions including dry eye and post- traumatic stress disorder (PTSD). Full understanding of their structures will hopefully lead to development of an effective drug to regulate the protein's function.

Researchers have discovered a new energy-efficient method to generate and release substantial volumes of metastable, nano-scale gas bubbles in water, in excess of natural solubility levels. The discovery has the potential to disrupt a number of industries including; wastewater treatment, gas storage, food, bio-pharma and brewing.
