FPL Scientist Recognized by Forests Magazine

Research Forest Products Technologist Xiping Wang has recently been announced by Forests Magazine as a winner of the Best Cover Awards for his collaboration on the cover article “Non-Destructive Evaluation Techniques and What They Tell Us about Wood Property Variation.”

“A few years ago, Laurence Schimleck, the senior author of this article, and I met at a professional conference and discussed the possibility of writing a comprehensive review paper on a range of nondestructive testing technologies for wood quality assessment, especially on standing trees in forests,” Xiping explained. “My expertise is primarily in developing acoustic wave-based technologies for wood quality evaluation. In this article, I contributed two sections: Acoustics and Pilodyn, as well as some contents in discussions and tables.”

Xiping was also the photographer for the photo chosen by Forests for its cover.

FPL’s XyloTron Helps Timber Industry in Ghana

The XyloTron, a Forest Products Laboratory (FPL)-developed, field-deployable digital imaging device for wood, is having a positive impact on timber industries worldwide.

In 2018, a Ghanaian wood identification expert and three inspectors from the country’s Timber Industry Development Division, spent time at FPL learning how to use the Xylotron so they could train others to use the equipment when they returned home.

This recently released video tells the story of how the device is now being used in Ghana, where more than two million people earn their living in the wood and timber industry.

Murder Mystery: When the Witness is a Tree

Could this wounded tree provide clues to what happened to Bonnie Woodward?

In late June of 2010 Bonnie Woodward went missing. An acquaintance, Roger Carroll, was an early suspect for her assumed murder but police found no evidence of any crime, and never found her body.  For nearly eight years she remained missing and the case went cold.  It was only after Roger Carroll admitted to his wife that he had killed Woodward that critical new information came to light.

 A witness claimed Carroll shot Woodward at his rural Jersey County, Illinois, home, burned her remains in a huge brush pile that he stoked for several days, then used a tractor to push all the evidence – or so he thought – into a creek. Carroll was taken into custody in April of 2018 and charged with first-degree murder.
