...young. Dr. Sandra Levey of New York City's Lehman College says 13% of teenagers aged 16 to 19 already show signs of noise-induced hearing loss. The inner ear contains small hair cells that vibrate against an inner membrane, generating an electrical signal that the brain interprets as sound, Levey explains. When bombarded by loud volumes over an extended period of time, these hair cells die off. The result is hearing loss, and potentially an array of other nasty consequences. A study conducted by Levey and Dr. Brian Fligor of Harvard University, which is nearing completion, suggests teens with...
...replace his dead brother within his entourage at the carnival. So he goes after Peter Petrelli by pretending to be someone he previously saved and suing him for injuries. They bond. And simultaneously we are introduced to a new character Emma, who is deaf but can apparently see sound in the form of colors. At the end, Samuel collapses a big fancy house into a sinkhole...
Most useless hero: Emma. Seeing sound as colors is kind of a cool effect, but we wish she could have done something interesting with it this week...
...environmental operations at the NSF. "The risk to people for not pursuing this type of research is simply not part of the story," Lang says. In the past, explosives like dynamite were used to create seismic waves. Improvement of recording devices and computer analysis has further decreased the airgun sound intensity required for geological research. Airguns are "the best existing technology to produce the desired type of sound," he says. Lincoln Hollister, professor of geosciences at Princeton University, also rejects claims that airgun use is correlated with damage to marine life, like lesions to the ears and brains or mass...
...about the environment - so they should do everything above board and by the book, without any reluctance," Rose of HSI says. "It is highly likely that there is better technology out there." With so many suggestions coming from both sides, common scientific goals - creating lower-intensity devices that create sound waves, understanding geologic processes and preserving marine mammals' safety - may be getting drowned...
