The Coast Guard is hoping for an 8.4% increase in funding, with a fiscal 2019 budget request that seeks $750 million for the service's first new heavy icebreaker in four decades. The Guard has pushed hard for additional funds in a public relations campaign that emphasizes its role in maintaining national security.
A lawsuit filed by the state of Louisiana contends that work done by the US Army Corps of Engineers on the Intracoastal Waterway accounts for the "vast majority" of the state's erosion problems. In the suit, Attorney General Jeff Landry alleges that the Corps failed to maintain the canal at the width mandated in a 1926 agreement.
A new database that includes all the practices implemented through county land conservation departments working with the landowners and producers is being used to protect Wisconsin's Fox-Wolf Watershed. An alliance for the watershed will use the data to judge the best methods for preventing runoff from endangering the state's waterways.
Many US coastal communities are finding dual advantages in clearing clogged inlets of sand that, in turn, can be used to restore eroded beaches. However, the solution can be costly, and concerns have been expressed that the process can disturb wildlife.
The Southern Nevada Public Land Management Act would lose $230 million in federal funding over the next three years under a budget proposal published by the Interior Department. Past funding has been "critically important to protect the environment and communities from catastrophic wildfire at Lake Tahoe," said Thomas Lotshaw, Tahoe Regional Planning Agency spokesman.
Flooding and erosion in India's state of Assam is about to get attention from the World Bank. The new five-year plan will draw on the latest technologies for a broad-based approach and include initiatives to make better use of monsoon-generated waters from the Brahmaputra River.
A three-step strategic approach to urban wastewater treatment consisting of minimization and prevention, treatment and stimulated natural self-purification was the subject of an international study in Colombia's Upper Cauca River Basin. Compared with traditional end-of-pipe solutions, 3-SSA was found to reduce initial investment and subsequent costs for operation and maintenance.
The task of realigning the fragments of a broken thighbone can be delicate and require repeated imaging while calling for enormous amounts of force to overcome the resistance of large surrounding muscles. To address this issue, Mohammad Abedin-Nasab, a professor of biomedical engineering at Rowan University, is developing a surgical robot that can manipulate these bone fragments guided by image-processing software that eliminates the need for continual radio imaging.
Nuclear technology may provide a solution for eliminating hunger in Africa. Specifically, researchers in the Central African Republic are looking into irradiation techniques that bring about genetic variations to produce healthier, higher-yield cassava plants, a local staple and the basis for many dishes.
A robot measuring 800 microns long can tumble end over end on command to traverse the difficult terrain inside the human body and deliver drugs. The trick to the tiny microTUM device developed by Purdue University engineers lies in its magnetic ends, which can be manipulated with an external rotating magnetic field.
