New method for producing carbon nanoscrolls, an alternative to nanotubes

Chemists report in the Feb. 28 issue of Science a room-temperature chemical method for producing a new form of carbon called carbon nanoscrolls. Nanoscrolls are closely related to the much touted carbon nanotubes — which may have numerous industrial applications — but have significant advantages over them, said Lisa Viculis and Julia Mack, the lead authors of the article and graduate students in the laboratory of Richard B. Kaner, UCLA professor of chemistry and biochemistry.

Birth Control Pill May Provide Relief for PMS

The physical and emotional symptoms associated with a woman’s menstrual cycle were significantly reduced in women taking the combination of drospirenone and ethinyl estradiol contained in the oral contraceptive Yasmin, as reported in a study published in the Journal of Reproductive Medicine. This reduction of menstrual-related symptoms led to a significant improvement in women’s health-related quality of life and overall sense of well-being.
