CAS REGISTRY approaches 50 millionth registration


CAS, a division of the American Chemical Society, announced that it is on track to register the 50 millionth unique chemical substance on September 7. This milestone came quickly, since it was only 9 months ago that CAS registered its 40 millionth substance. In contrast, it took 33 years for ...


New insights into the 'smell of death' could help recover bodies in disasters and solve crimes


In an advance toward the first portable device for detecting human bodies buried in disasters and at crime scenes, scientists report early results from a project to establish the chemical fingerprint of death. Speaking here at the 238th National Meeting of the American Chemical Society (ACS), ...


Faster, more cost-effective DNA test for crime scenes, disease diagnosis


Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction (PCR) a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR in ...


New nanoparticles could revolutionize therapeutic drug discovery


A new protein stabilisation technique has been developed by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) which could lead to 30 per cent more proteins being available as potential targets for drug development - opening up exciting possibilities in drug ...


University of Toronto chemists uncover green catalysts


A University of Toronto research team from the Department of Chemistry has discovered useful "green" catalysts made from iron that might replace the much more expensive and toxic platinum metals typically used in industrial chemical processes to produce drugs, fragrances and flavours. The ...


CAS Registers 40 Millionth Substance in CAS registry


CAS Registry now includes 40 million organic and inorganic substances. CAS Registry Number(R) 1073662-18-6 recently was assigned to an azulenobenzofuran derivative. The 40 millionth substance was identified by a team of CAS scientists,C.H. Oh,J.H. Lee,S.J. Lee,J.I. Kim, andC.S. Hong. The journal ...


That tastes -- sweet? Sour? No, it's definitely calcium!

That tastes -- sweet? Sour? No, it's definitely calcium!


Chemists in Philadelphia are reporting a discovery that could expand the palate of human tastes — sweet, sour, salty, bitter, and savory — to include a new taste sensation that they term "calcium." In a report at the 236th National Meeting of the American Chemical Society, scientist Michael G. ...


Toward world's smallest radio: nano-sized detector turns radio waves into music


Researchers in California reported development of the world's first working radio system that receives radio waves wirelessly and converts them to sound signals through a nano-sized detector made of carbon nanotubes. The "carbon nanotube radio" device is thousands of times smaller than the ...


New 'self-exploding' microcapsules could take sting out of drug delivery


Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vaccines inside the human body weeks or even months after injection. The study, by researchers at Ghent University and the Universite Catholique de Louvain, is scheduled to appear in the ...
