A substance found in saliva could help develop new drugs to treat antibiotic-resistant infections. It raises hopes for people with diseases like HIV and cystic fibrosis, who regularly develop infections that are difficult to treat with conventional drugs.

Dr. Libuse Bobek, of the University at Buffalo School of Dental Medicine in New York, discovered the saliva chemical, which kills fungal agents like candidiasis, cryptococcosis and aspergillosis that can threaten people whose immune systems are compromised. It also destroys several bacteria, including E.coli and P. gingivalis, which cause serious intestinal and oral infections, and S. mutans, which causes tooth decay.

Dr. Alison Wren, Research Fellow at Imperial College, London has isolated a ?hunger hormone? that dramatically boosts human food consumption. Scientists have known for some time that the hormone stimulates hunger in rats, but they had never been able to identify its effects in humans. Now they have shown that it can make people so ravenous they eat nearly a third more food than usual.

The Stanford program is called the Database on Nuclear Smuggling, Theft and Orphan Radiation Sources and is intended to help governments and international agencies track down lost nuclear material worldwide. Right now, many governments have national tracking programs but fail to share their information with other countries.
