One of the great perils posed by the world's warming waters is glaciers melting in Antarctica, and researchers now have determined which type of geoengineering offers the best possible solution. They say the best bet is building a berm tall enough to protect the frigid continent's Thwaites Glacier from being melted by warm waters.

Dangerous bacterial infections can produce symptoms comparable to those produced by viruses but can be difficult to validate. A new device from researchers at McGill University speeds detection with placement of a small sample in a chamber whose rough surface contains tiny 3D structures that capture individual bacteria, allowing for identification in minutes.

Sandvik has two decades of experience with the technology that provides self-driving heavy equipment for the construction and mining industries. The company's latest vehicles can operate independently through the entire mining cycle of loading, hauling and dumping as demonstrated with one 38-ton example maneuvering through an intricate maze of 589 glass sheets.

Eben Upton's Raspberry Pi has served as a centerpiece for the maker subculture, and the result has been a proliferation of drones, robots, automation systems and a good deal more. Upton reflects on his product and makers and how their work shines a fresh light on "the creative, entrepreneurial aspects of engineering practice."

The 128-foot, 600-passenger ferry Enhydra is the largest vessel of its kind in the US to run on lithium-ion batteries and plug-in electric technology. Last week's maiden voyage in San Francisco Bay demonstrated the environmental value of electric power on water in what its owners hope will inspire wider usage across the maritime industry.

A myoelectric robotic arm that responds to its wearer's muscle inputs enables Jason Barnes to continue pursuing his dream of being a rock drummer. The arm, developed with Georgia Tech professor Gil Weinberg, is augmented by two motors that enhance speed and dexterity and leverages deep learning to convert muscle signals into drumstick movement.

A new taxing district devoted to funding erosion control in Montauk, Long Island, has won the support of the East Hampton Town Board. The issue was prompted by storms that exposed some of the 14,000 geo-textile sandbags the Army Corps of Engineers buried in 2016 as an erosion-control measure.

A study used 12 under-drained, experimental bio-retention water enclosures to gauge the effects of plants and microorganisms on the long-term treatment efficacy of bio-retention for stormwater management in the Pacific Northwest. Results pointed to the importance of physical and chemical variations and suggested further research on the use of fungal-inoculated mulch as a means to curb phosphorous leaching from soils.

Encroaching saltwater from rising seas poses an existential threat to coastal wetlands, but moving wetlands inland could save them, states a study in science journal Nature. The study also found that wetlands are not likely to be wiped out, despite previous studies indicating that up to 90% of wetlands could be lost due to changing weather patterns.
