Study finds no relationship between respiratory illnesses, mists from 'dental aerosols'
A study by dental researchers from the University at Buffalo School of Dental Medicine offers a preliminary answer to the question of whether breathing in mists spun off by dental drills causes respiratory illness.

Authors of a research letter in this week's issue of THE LANCET are calling for EU guidelines to be reviewed after results of research which shows that patients only given qualitative information about the side-effects of drugs substantially overestimate their personal risk.

MGH researchers unravel structure of a key protein involved in tumor angiogenesis and metastasis
Cancer cells need a blood supply to grow. A key receptor protein called the alpha V beta 3 integrin directs formation of new blood vessels by binding to other proteins, such as angiostatin and endostatin, produced by tumor cells.
