A study in the journal Proceedings of the National Academy of Sciences says that babies born via caesarian may be more prone to asthma and other illnesses because they don’t get an immune system boost from natural birth:
Scientists have shown that a natural delivery exposes babies to a host of bacteria that prime them to fight of germs and allergies as they grow up.
Babies born through the more clinical process of a C-section miss out on this natural boost.
Next, new research says blasting your iPod or other MP3 devices could cause temporary hearing loss. Experts say there are "safe settings" that can prevent this; they say you can listen all day at a volume level of 6 or 60 percent:
Occupational noise exposure can lead to noise-induced hearing loss, but less is known about the long-term and short-term effects of recreational noise -- including exposure to loud music at a concert, on your iPod, or at noisy sporting events including the World Cup where revelers regularly blow, buzz or hunk their vuvuzela horns.
Excessive noise produces changes in the ear’s organ of Corti, which is the organ in the inner ear that contains hair cells. Outer hair cells are more vulnerable to noise than inner hair cells.
A 6-year-old in the U.K. nearly went blind in one eye, but can now see again thanks to his doctor's prescription to play Super Mario for two hours a day. The unusual therapy is thought to help weak eyesight because computer games train the eye to focus:
Mr. Nischal of Great Ormond Street Children's Hospital, said the therapy helped children with weak eyesight because computer games encourage repetitive eye movement, which trains the eye to focus correctly.
"A games console is something children can relate to. It allows us to deliver treatment quicker," he said.
