Passive smoking turn kids antisocial

Kids exposed to second-hand smoking in early age may develop aggressive behaviour, say researchers from University of Montreal in Canada. "Those having been exposed to second-hand smoke, even temporarily, were much more likely to report them-seleves as being more aggressive by the time they finished fourth grade,"said a researcher.

Itching is not about just about sratching

The molecule behind itch has been discovered, a new study says. The research done on mice by the National Institute of Health, USA identifies the small molecule, natriuretic polypeptideb (Nppb) as being behind the sensation. The molecule released in the spinal cord triggers a process that is later experienced in the brain as itch.
