Let that dirt be!

Article Abstract:

A study of polycyclic aromatic hydrocarbons (PAHs), conducted by a research team from Stanford University in California, revealed that a number of ground pollutants tend to bind to dirt particles that they become harmless. The study, conducted on accumulated PAHs at the bottom of a harbor in Milwaukee, WI, suggests the possibility of mixing those particles with sediments and using microbes to degrade PAHs.

A Messenger from Eden for crop pests and diseases

Article Abstract:

Eden Bioscience has developed a new biochemical pesticide that improves plant growth and immunity to diseases and insect pests. The pesticide called Messenger has harpin as its active ingredient, which is a naturally-occuring protein produced by bacterial plant pathogens such as Erwinia amylovora. Tests done on tomato plants show that Messenger improves crop yields by 10 to 22% while reducing chemical usage by as much as 71%. Messenger also has no adverse side effects to birds, mammals and fish.

Pushing the limits of turbine efficiency

Article Abstract:

New gas turbines that are cleaner-burning and with lower emissions of nitrogen oxide and carbon monoxide have been developed under the Advanced Turbine Systems Program of the US Dept of Energy. A similar program has been initiated at the National Energy Technology for the design of turbines that can achieve efficiences of 60%. The department has also started a third program spearheaded by Solar Turbines for innovative small industrial turbines that will reduce the cost of producing electricity for small utilities.
