Footbridges, also commonly known as pedestrian bridges, used to link two areas are nowadays becoming beautiful works of engineering and architecture that add visual value to a landscape. While often wondrous to look at, these small structures can come at a high price if not constructed in a key location or if designed with typical materials.

Soft robots — which don’t just have soft exteriors but are also powered by fluid flowing through flexible channels — have become a sufficiently popular research topic that they now have their own journal, Soft Robotics. In the first issue of that journal, out this month, MIT researchers report the first self-contained autonomous soft robot capable of rapid body motion: a “fish” that can execute an escape maneuver, convulsing its body to change direction in just a fraction of a second, or almost as quickly as a real fish can.

Osmosis, a vital biological process, is finding its way to the clean and renewable energy technology. Researchers at the Chemical and Biomolecular Engineering Department at the National University of Singapore and at the Water Desalination & Reuse Center at King Abdullah University of Science and Technology fabricated polyethersulfone (PES) thin film composite membranes with hollow fiber supports in order to achieve a membrane with high mechanical strength and high flux—a membrane specifically designed to optimally procure the osmotic energy generated by seawater brine.

A team of MIT researchers has used a novel material that’s just a few atoms thick to create devices that can harness or emit light. This proof-of-concept could lead to ultrathin, lightweight, and flexible photovoltaic cells, light emitting diodes (LEDs), and other optoelectronic devices, they say.

Researchers from North Carolina State University have developed a computational tool designed to guide future research on biochemical pathways by identifying which components in a biological system are related to specific biochemical processes, including those processes responsible for gene expression, cell signaling, stress response, and metabolism.

Encryption might not be enough for all that data stored in the cloud. An analysis of usage patterns — which files are accessed and when — can give away secrets as well. Computer scientists at Brown have developed an algorithm to sweep away those digital footprints. It’s a complicated series of dance-like moves they call the Melbourne Shuffle. To keep data safe in the cloud, a group of computer scientists suggests doing the Melbourne Shuffle.
