Deuterated pyridine adopts a different crystalline form: a useful effect for pharmaceuticals?The nuclei of ordinary hydrogen atoms contain only a single proton. If a neutron is added, the hydrogen becomes deuterium. In principle, molecules that contain deuterium in place of hydrogen atoms are chemically identical. However, there can be significant differences. Thus "heavy water", water with molecules that contain deuterium in place of hydrogen, is toxic because it disrupts highly sensitive...

By Castelvecchi, Davide Bond lengths are different in heavy, light water molecules Heavy water is not just heavier. Swapping each H in H2O with a D- hydrogen's isotope deuterium - changes water's properties. The deuterium version is mildly poisonous, and its freezing point is 4[degrees] Celsius, instead of 0[degrees]C Such differences reveal that quantum effects, which aren't usually manifest to the naked eye, rule in ordinary water, researchers suggest. Alan Soper of the Rutherford...

By Mark John BRUSSELS (Reuters) - Iranian agents have tried to obtain from South Korea a substance that can be used to boost nuclear explosions in atomic weapons, an Iranian exile group said on Thursday. The National Council of Resistance of Iran (NCRI), which has in the past provided accurate information on hidden Iranian nuclear activities, said Tehran had used front companies to obtain the substance, a hydrogen isotope known as tritium. "The regime has tried to smuggle it in from...

Sudbury Neutrino Observatory -- The Sudbury Neutrino Observatory (SNO) is taking data that has provided revolutionary insight into the properties of neutrinos and the core of the sun. The detector, shown in the artist's conception below, was built 6800 feet under ground, in INCO's Creighton mine near Sudbury, Ontario. SNO is a heavy-water Cherenkov detector that is designed to detect neutrinos produced by fusion reactions in the sun. It uses 1000 tonnes of heavy water, on loan from...
