New research vessels will set out on missions to fill many of the blank spots in our understanding of the oceans. Among several notable vessels now being designed and built are polar explorers from the UK and China.
A keel authentication ceremony marked the official beginning of work on another of the Navy's San Antonio-class amphibious dock ships. The future USS Fort Lauderdale is being built by Huntington Ingalls at its Mississippi facility.
Sediment is often treated as waste, but it also can be a valuable resource for soil and habitat replenishment. That's the case with sediment dredged from waterways in the UK's Broads region, where sediment is dredged annually to keep navigation open and then used to build new habitats, enhance flood bank protection and enhance agricultural soil.
Weather-related disasters are partly predictable, but willful ignorance and irresponsible public policy tend to make the consequences of such events much worse than they need to be, writes Tom Still, president of the Wisconsin Technology Council. Houston is a prime example of this, with policies there actually worsening the area's natural disadvantages when hurricanes strike, and the devastation wrought by the most recent wildfires in northern California is another example; both examples hold lessons for Wisconsin and its recent battle over high-capacity wells in the center of the state.
Hundreds of rain gardens in Clintonville, Ohio, have curbed sanitary-sewer overflows and reduced flooding, officials there say. However, some residents say they pose traffic hazards, could be toxic and will harbor mosquitoes.
Sixty-one acres of burned soil are being covered with 80,000 pounds of mulch in Sugar Loaf Butte, Mont., to deal with fire-induced hydrophobicity and prevent flooding and erosion caused by the wildfires in the area.
North Carolina's coastal regions have an advantage dealing with changing weather patterns and rising seas, as no major cities are complicating matters, writes The Nature Conservancy's Brian Boutin. This allows for the kind of sensible protective measures that rely on and enhance nature with ecosystems, reefs and coastal forests, which tame the risk of flooding while enhancing water quality.
A five-year plan to clean up contamination in Michigan's Kalamazoo River is advancing with clearance by the Environmental Protection Agency. The $46 million project includes removal of a dam at Otsego City and covers nearly 2 miles between there and Plainwell.
A new wound dressing that could replace stitches and skin grafts promotes healing while minimizing the risk of infection and scarring. The key is using the patient's cells in an extracellular matrix forming a scaffold for healing, along with a natural human antimicrobial and a peptide to reduce inflammation.
Factory robots need to move, and how capable they are of that depends crucially on the number of planes of motion on which they operate. That's where axes come in, defining which robotic arms can rotate and the complexity of movements that can be programmed, with six axes commonly found in factories today.
