A new nano-biochip tht can analyze a few drops of saliva could possibly help give early diagnosis of a heart attack, report researchers at the University of Texas at Austin. The device, the size of a credit card, can produce results in as little as 15 minutes. It could someday be used to assay a patient's saliva on board an ambulance, the doctor’s office or even the local drugstore, helping prevent unnecessary damage from cardiac disease.

A personal sensor system which continuously monitors the environment air around persons prone to asthma attacks has been developed at Georgia Tech Research Institute. Designed to be worn in the pockets of a vest, the system should help researchers understand the causes of asthma attacks.

The system measures airborne exposure to formaldehyde, carbon dioxide, ozone, nitrogen dioxide, temperature, relative humidity and total volatile organic compounds (VOCs). VOCs are emitted as gases from products such as paints, cleaning supplies, pesticide formulations, building materials and furnishings, office equipment and craft materials.
