Since the advent of DNA testing in 1985, biological material (skin, hair, blood and other bodily fluids) has emerged as the most reliable physical evidence at a crime scene, particularly those involving sexual assaults. DNA, or deoxyribonucleic acid, contains the complex genetic blueprint that distinguishes each person. Forensic testing can determine if distinctive patterns in the genetic material found at a crime scene matches the DNA in a potential perpetrator with better than 99% accuracy. In 1987, Florida rapist Tommie Lee Andrews became the first person in the U.S. to be convicted as a result of DNA evidence...
...even slower than today's; range was limited and batteries died in less than a year. Now they can travel as far as 100 km on a full charge, more than enough for a day's riding. But batteries remain the weak point. Most e-bikes rely on lead-acid batteries, cheap century-old technology unsuitable for the growing demands of daily commuting. "The battery is the key limiting factor," says Jonathan Weinert, a transportation expert who wrote his doctoral dissertation on electric bikes in China...
...While lead-acid batteries are improving, Weinart says that electric bikes will create a larger market for lithium-ion batteries - a newer, lighter technology whose development is key for the future of electric vehicles. Already Giant, the world's largest manufacturer of pedal bicycles but a small player in the Chinese e-bike market, has made headway in northern Europe selling high-end e-bikes that use lith-ion batteries. "To the extent that the electric bike industry can help get battery costs down, test the technology and get it in the market, that may lead" the development of electric...
...ATTACKS At least 84 Afghan girls were admitted to a hospital in the small town of Mahmud Raqi for nausea and headaches after the third apparent poisoning at a school in less than three weeks.
