Two MIT students have found a way to get a spaghetti noodle to split in half instead of into several pieces -- an iteration of a problem that perplexed famed American physicist Richard Feynman -- by using a device that bends and twists it to apply pressure evenly to both ends. The students believe insight from their experiment can be used to study fractures for a wide range of materials.
Robots typically cannot be productive without power sources, but engineers at Caltech have developed a self-sufficient, 3D-printed robot that doesn't need batteries or fuel to power itself. Instead, the robot comes with a paddling mechanism that is activated by rising temperatures.
A team of Peruvian students has made an award-winning device that collects potable water in Peru's Amazon rainforest region. The system involves a set of vertical tubes that can double as walls in homes while collecting water from the roof, treating it and then delivering it to water networks.
Tangier Island in Chesapeake Bay faces an existential threat due to changing weather patterns that lead to rising water levels and increased erosion. The Army Corps of Engineers is planning to address erosion on the island with a $3 million jetty, and the Corps is seeking approval for a study examining the best ways to protect the island.
The Navy is testing a system that can be lowered from a helicopter to destroy enemy sea mines. The technology, which is expected to be deployed within a few years, involves a warhead equipped with sonar and video that is connected via a fiber-optic link to a console on the helicopter.
The Navy has awarded a $47 million contract to Lockheed Martin to upgrade the AN/BLQ-10 electronic warfare system for submarines. The system automatically detects, classifies and identifies potentially hostile radar and communications signals.
Welding problems with missile tubes identified by a subcontractor hold the potential to delay construction of the first Columbia-class submarines, the next iteration of Virginia-class submarines and the UK's Dreadnought submarines. General Dynamics Electric Boat and the Navy are looking into the issue.
Bath Iron Works will provide engineering, planning, ship configuration, material and logistical support for modernization of the Navy's littoral combat ships under a $33.6 million modification to an existing contract. The original $100 million contract was awarded in 2014.
Join Rep. Rob Wittman, R-Va., on the opening day of the Technology Enablers for Digital Engineering workshop, to be held Oct. 16-17. This event is in Dahlgren, Va., with the first day unclassified and the second day classified. Learn more online.
