Health News: Silica nano-particles could repair damaged teeth ♦ Using ultrasound to clean medical instrument ♦ Suicide greatly underestimated in U.S.

MN salmonella outbreak blamed on tomatoes served at chipotle restaurants Tomatoes served at 22 Chipotle Mexican Grill locations in Minnesota were the source of the recent Salmonella Newport outbreak which sickened 64 people and hospitalized nine of them. All are recovering, according to the Minnesota Department of Health.
Epidemiologist says suicide, death from intentional self-injury is greatly underestimated in U.S. Suicide is the 10th leading cause of death in the United States -- greater even than traffic crashes. A professor of epidemiology says the problem is bigger and proposes a way to address it.
International team discovers natural defense against HIV A new natural defense against HIV infection has been discovered by researchers. The team's discovery focuses on ERManI, a protein that prevents the HIV virus from replicating.
Using ultrasound to clean medical instruments A pioneering ultrasonic device can significantly improve the cleaning of medical instruments and reduce contamination and risk of infection. StarStream makes water more efficient for cleaning by creating tiny bubbles which automatically scrub surfaces. The device supplies a gentle stream of water through a nozzle that generates ultrasound and bubbles, which dramatically improve the cleaning power of water reducing the need for additives and heating.
Tiny silica particles could be used to repair damaged teeth, Researchers have shown how the development of coated silica nanoparticles could be used in restorative treatment of sensitive teeth and preventing the onset of tooth decay
