Why does chopping an onion make you cry? Unstable chemicals. Onions produce the chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes' lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit (Imani et al, 2002). Lachrymatory-factor synthase is released into the air when we cut an onion. The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid. ...

Why do some people have all the luck while others are perpetually unlucky? Professor Richard Wiseman of the University of Hertfordshire was determined to get to the scientific bottom of the phenomenon of luck, and what he discovered may surprise you: I placed advertisements in national newspapers asking for people who felt consistently lucky or unlucky to contact me. Hundreds of extraordinary men and women volunteered for my research and over the years, have been interviewed by me. I have monitored their lives and had them take part in experiments. The results reveal that although these people have almost no insight into the causes of their luck, their thoughts and behaviour are responsible for much of their good and bad fortune. Take the case of seemingly chance opportunities. Lucky
