Graphene is a type of graphite mineral. Experts often call it 'The Material of the 21st Century' because of it' s special properties. Some U.S. companies are already using graphene for new technology products.
Graphene is often described as a one-atom-thick layer of carbon. The material has some extraordinary properties. It is 100 times stronger than steel of the same thickness. The nearly transparent material also carries heat and electricity very well.
North Korea has a team of roughly 3,000 cyber soldiers dedicated to launching attacks at Western interests in the private and government sector, according to Kim Heung-gwang, a former professor at North Korea’s Hamhung University of Computer Technology, a key military training facility. Heung-gwang, urging Western governments to do more to counter North Korean hacking, said the country’s hackers are targeting Western nuclear power plants, transportation networks, and electrical utilities.
Cellphone, Internet, and telephone services across half of Arizona went dark on Wednesday after vandals sliced a sensitive fiber optic cable, according to those familiar with the situation. The incident is raising concerns about the safety of U.S. infrastructure.
Technology is continually expanding and ever changing. The first cellphones were large, difficult to carry, and in some cases had to be transported in a suitcase. As technology advanced,
cellphones became small enough to fit into pants or shirt pockets. The trend is now reversing back to large phones designed to store substantial amounts of information and to display the data on oversized screens. Many, if not most, people with cellphones
have enormous amounts of information about their lives stored on this single device. People rely on their cellphones to wake them, deliver the morning news, and keep them on track throughout the day. When cell towers cease to function after a disaster, those
who rely so heavily on these devices still could utilize their cellphones beyond the traditional method. There are now applications (apps) on the market that do not require a cellular connection and can provide the owner with useful information and even connectivity
to emergency and community services.
The Federal Communications Commission is considering changing the provider of the local number portability administrator in the summer of 2015, which may have consequences that affect public safety capabilities. Full article.
