Five years after the Chesapeake Bay blue crab fishery was declared a federal disaster an annual scientific survey shows the population is far below the previous year, but scientists are not too worried.
Scientists from Virginia and Maryland conduct the so-called "winter dredge survey" while crabs are burrowed in the mud. Last year a baby crab boom led to the highest count in 20 years.
Virginia’s Secretary of Natural Resources is warning that supplies of groundwater in the eastern part of the state are running dangerously low.
Speaking at a conference on the environment at Virginia Military Institute, Doug Domenech said stores are down due increased demand from new homes, shopping centers and industrial parks.
The state is now urging industries that don’t need clean water to consider finding other sources, such as rivers, and the legislature recently approved money to monitor areas where ground water is in decline.
April may be known for more than showers this year. Some insects will make a return this spring after nearly two decades underground. . .
These creatures look a little frightening with their red eyes, black bodies and gold wings but there’s nothing to fear with the cicadas about to emerge from the earth. Virginia Department of Forestry spokesman Chris Asaro says that’s where they’ve been waiting for the past 17 years.
Scientists in biological systems engineering at Virginia Tech have succeed in using xylose, a sugar found in plants to produce large quantities of hydrogen in an environmentally friendly way.
Unlike current methods of making hydrogen gas, Associate Professor Percival Zhang’s process is done at low temperatures, uses no heavy metals and releases almost no green house gases. His team designed an enzyme cocktail for splitting of the hydrogen. The result is energy production at a rate of more than 100% efficiency; a level current methods do not reach.
