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.
The ecological importance of phytoplankton, microscopic plants that free-float through the world's oceans, is well known. Among their key roles, the one-celled organisms are the major source of sustenance for animal life in the seas. Now, researchers at Scripps Institution of Oceanography in San Diego say that phytoplankton exert a significant and previously uncalculated influence on Earth's climate.
