H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

Bathing better than pethidine as pain relief during labor: Survey

According to a large survey of new mothers, a bath or a shower relieves pain in childbirth more effectively than anaesthetic gas or pethidine. The survey also found that breathing techniques, massage, hot packs and hypnotherapy were more effective than pethidine, a strong analgesic given by injection, and nitrous oxide, that is an anaesthetic gas. The survey has renewed the debate of drug overuse during child birth that could potentially harm babies.
