The hotly disputed Mountain Valley Pipeline in West Virginia is now the subject of scrutiny by the state's Department of Environmental Protection. The builders have been put on notice that they're violating erosion control regulations and allowing sediment to enter waterways.
Heavy rains washing through construction sites are a suspected source of pollutants leading to early blue-green algae blooms in Wisconsin's Lake Mendota. Construction crews are taking precautions and officials are monitoring the situation carefully, but the problem persists.
The Mississippi River is seen as a rich possible source of the sediment needed to help rebuild Louisiana's shrinking coastline. State officials would like to create sediment diversions along the river to channel these waters into marshland that is dying.
Cornwall, Pa., authorities are taking a pass on a proposed state grant that could have been used to protect water supplies. It turns out that any project undertaken with the funds -- assessed against Sunoco pipeline construction violations -- would not have counted toward meeting the state mandate for curbing stormwater runoff in waterways.
A study of three urban watersheds assesses stroke scaling as a way to generalize a storm sewer network on a flood simulation as judged by total inflow of the outfalls and flooding results. Results suggested that differing sewer network complexities had no bearing on the outfall's total inflow in an area with a single drainage system but did make a difference in an area with more than one system.
New siding technology from Ply Gem Siding Group called SolarDefense Reflective Technology has three layers that create stronger light reflection and heat resistance. The new tech enhances the functionality from the existing Mastic by Ply Gem line.
A smart gym for infants can help single out developmental difficulties early on through a variety of interactions. The robotic device is the brainchild of professors Michelle J. Johnson and Laura Prosser of the University of Pennsylvania's Perelman School of Medicine, after Johnson had worked with similar robotic systems designed to assist those suffering from cerebral palsy.
Fewer than half of patients receiving immunotherapy for treatment of leukemia see results, but a new, softer mesh used in scaffolding to produce T cells may help by yielding a much higher proportion of functional cells. The development by Columbia University biomedical engineers Lance Kam and Helen Lu replaces the hard plastic beads now used to grow the cells.
The quantum dots used in advanced TV sets and solar cells are joining in combination with green tea leaves to fight lung cancer. Researchers at the UK's Swansea University have harnessed the humble anti-oxidative and fluorescent power of green tea leaves in the form of quantum dots to help identify cancerous cells and, as it turns out, help destroy them.
The future viability of renewable energy sources may depend on the ability to store and then use surplus energy, and metals heated to extremely high temperatures is seen as one solution. Pumping molten metals safely is the object of research by professor Asegun Henry and his team at Georgia Tech's Woodruff School of Mechanical Engineering, where they're working on a ceramic pump that can move molten tin heated to 1,600 kelvins.
