Crawford studied the greenhouse gas emissions of wooden and reinforced concrete sleepers based on one kilometer (0.62 miles) length of track over a 100-year life cycle. He found that emissions from reinforced concrete sleepers can be from two to six times lower than those from timber. "The results suggest strongly that reinforced concrete sleepers result in lower life cycle greenhouse emissions than timber sleepers," the report states. JS

Sweet deception: New test distinguishes impure honey from the real thing
Journal of Agricultural and Food Chemistry
Here's some sweet news for honey lovers: Researchers in France are reporting development of a simple test for distinguishing 100 percent natural honeys from adulterated or impure versions that they say are increasingly being foisted off on consumers. Their study appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication.
Bernard Herbreteau and colleagues point out that the high price of honey and its limited supply has led some beekeepers and food processors to fraudulently make and sell impure honey doped with inexpensive sweeteners, such as corn syrup. These
