A fall tradition is to catch the monarch migration in late September and Early October. This year, however, there may not be much to see.
It takes four generations and up to 3,000 miles for the monarch migration to make its roundtrip each year. Virginia is one of the many and varied locations in which one generation of the monarch will breed.
Researchers at Virginia Tech have come up with a plan for a new kind of helmet for construction workers that can monitor their exposure to carbon monoxide and warn them before it becomes dangerous.
Carbon Monoxide Poisoning kills hundreds of Americans each year and sends thousands more to the hospital. Construction workers face an especially high risk because they often work in enclosed spaces where exhaust from gasoline-powered hand tools can build up fast.
