Rabies is a preventable viral disease of mammals most often transmitted through the bite of a rabid animal. The vast majority of rabies cases reported to the Centers for Disease Control and Prevention (CDC) each year occur in wild animals like raccoons, skunks, bats, and foxes. The rabies virus infects the central nervous system, ultimately causing disease in the brain and death. The early symptoms of rabies in people are similar to that of many other illnesses, including fever, headache, and general weakness or discomfort.
World's longest railway tunnel to open after 17 years of construction: Trains in Switzerland will travel at 155mph through 35 miles of mountain. The new Gotthard Base Tunnel (GBT) will measure 35.4 miles in length and is 7,545 feet below the Gotthard massif.
A 31 mile-long tunnel sitting in a large cavern located 150 feet under the English Channel? Sounds like science fiction. The English Channel Tunnel is authentic, however, and carries people, cars, buses, and freight on high-speed trains between Folkestone, England, and Calais, France. Students research the English Channel Tunnel (called the Chunnel or Euro Tunnel) to learn more about how it was designed and constructed.
