Silicon nanoparticles now come in family of sizes and fluorescent colors

Scientists at the University of Illinois have developed a family of fluorescent silicon nanoparticles in various sizes and colors, which can be used for electronic displays, flash memories, and biomedical imaging. The particles are photostable and bright, allowing for non-invasive detection and study of biological phenomena.

Potato technology may help move mail

Researchers at Idaho National Laboratory are testing the effectiveness of ozone technology to sterilize mail by delivering high concentrations of ozone through potato conveyor belts. Preliminary results indicate that a 60-minute exposure to high levels of ozone inactivates anthrax spores, providing a potential tool against terrorism.

Study shows no benefit to home uterine monitoring

A multi-center study led by Dr. Jay Iams found that home uterine monitoring has no clinical value in predicting early birth, despite its widespread use for high-risk women. The study's results reinforce previous findings that ambulatory monitors are not more effective than other diagnostic tools or surveillance programs.

Predicting preterm birth still nearly impossible, study in New England Journal finds

A recent study published in the New England Journal of Medicine found that predicting preterm birth remains challenging due to low predictive value of current tests such as ultrasound and fetal fibronectin. The study suggests that prematurity in America is on the rise, with a 23% increase in premature births since the 1980s.
