A system that produces bubbles at the bow of a ship is said by inventor Chris Kinman to offer fuel savings of 25% to 35% while also boosting speed. The system consists of a bow-mounted stack of horizontal plates with spaces between that hold compressed air bubbles that in turn push seawater around the bow.

Technology being developed by the University of Connecticut engineering lab and the Naval Research Laboratory-Monterey promises better rerouting to help ships avoid severe storms. The Tool for Multi-objective Planning and Asset Routing, or TMPLAR, works something like Google Maps but with a great deal more complexity to account for numerous factors while calculating the safest and speediest routes.

Cell therapy products grown in petri dishes hold great promise for treatments that are largely thwarted by the difficulty of producing the therapies on a mass scale. But bioengineers at the University of Toronto and the University of British Columbia believe they have a solution following Quality by Design protocol, which uses target profiles of product identity, purity and potency, allowing engineers to validate product attributes of cells and other materials all along the production line.

Two layers of elastomer that can stretch as much as 400% sandwich a hydrogel serving as an electrode to produce a wearable skin that generates electricity from ordinary bodily movements. The STENG material, or "skin-like triboelectric nanogenerator," can be used to power things such as LED lights or a smartwatch, says inventor Zhong Lin Wang, professor of materials science and engineering at Georgia Tech.

The plan comes as San Diego's regional water agency plans to cut off its water to the lake at the end of the year, a move that will speed up the lake's evaporation.
