problem drug Pediatric ritalin use may affect developing brain in children, says a new study. Use of the attention
deficit-hyperactivity disorder drug may cause long-term changes in the brain, suggests a study on very young rats by researchers from the Weill
Cornell Medical College in New York. Ritalin--methylphenidate--a stimulant similar to amphetamine and cocaine, is one of the most prescribed drugs

hot news Mexican food is the oldest in the world, say scholars from the Smithsonian's National Museum of
Natural History in the us. Many consider the cuisine one of the world's tastiest. Plant remains from two caves in
southern Mexico analysed by the ethnobotanists show that as early as 1,500 years ago, people in the region enjoyed a spicy fare similar to the
Mexican cuisine today.
wireless wave Multi-gigabit wireless research may soon push wired computers and peripherals to the past.
Scientists at the Georgia Electronic Design Center at Georgia Institute of Technology are researching on the use of extremely high radio frequencies
to achieve broad bandwidth and high data transmission rates over short distances.
Within three years, this approach could result in what the researchers call the personal area network applications, including next generation home
multimedia and wireless data connections which would be able to transfer an entire dvd in seconds.
