The use of light could detect bacteria faster than the current laboratory-based detection system. Sheila MacNeil and researchers at Sheffield University have identified a mothod that could ascertain the presence of bacteria in less then a minute by using light, reported the only edition of BBC News. The technology could have wide applications in would healing, counter-terrorism and screening patients ofr MRSA (bacterial)infection,the experts said. The scientists are developing a portable kit in which specially designed molecules emit a light signal when bound to bacteria.
A man usually needs about two or three minutes of stimulation to have an orgasm,a woman generally needs 10 times more. For a man,an orgasm is instinctive.For a woman,it happens only after direct stimulation of the clitoris. A man's climax usually lasts for 10-13 seconds.For a woman,it lasts 6-60 seconds. A man must recuperate after an orgasm but a woman can have repeated orgasms within minutes or in rapid succession. Wonder why a man rolls over and sleeps after? During sex,his body releases oxytocin,a hormone that induces drowsiness.A woman is more relaxed after sex,which is why she wants to talk or cuddle.
