Lots of folks celebrate Christmas by stashing their presents under the same reusable plastic and aluminum wire Christmas tree every winter: it's a thoughtful, cost-efficient way to cut down on the amount of post holiday garbage that winds up in wood chippers or the local dump every year.
However, a lot of people still like to kick it old school with a cut-from-its-roots-and-left-to-slowly-die-in-a-pot-of-water conifer. They smell and look amazing...for a while. Once the presents have been unwrapped and the tree begins to brown, out the door it goes. Upwards of 30 million Americans wind up tossing out these Yuletide corpses every year. Happily, it looks like a scientist has sorted out a the means for making better use of these discarded trees once folks are finished getting their holly-jolly on with them.
The process involves breaking down a chemical called lignocellulose in needles of dead pine trees into a useful substance that could be used to make paint or artificial sweeteners and other wicked useful products.
Lignocellulose is ugly. No, really. Its chemical structure makes it difficult to use for biomass energy, and it serves little industrial purpose. Sheffield PhD student Cynthia Kartey’s work has focused on examining ways to make use of this material, and now she may be on to something.
Using heat and glycerol, Kartey was able to break down the pine needles into two components, one of which was made mostly of materials like glucose, acetic acid and phenol. All three have uses in other industries — glucose is used to make food sweeteners, phenol is used in products like mouthwash, and acetic acid for making adhesives, vinegar, and even paint.

Yes, that is actually Space.com’s brilliant headline on this story about a new discovery from data collected in 1986 by NASA’s intrepid spacecraft. When the probe neared Uranus (heh heh), it measured the planet’s surrounding magnetic field. Recently, NASA scientists Gina DiBraccio and Daniel Gershman analyzing Voyager’s old data found a “wobble” in Uranus’s magnetosphere […]

Cocaine, as they say, is one hell of a drug. In fact, it was recently shown in a study published in the Proceedings of the National Academy of Science to have greatly helped the re-wilding a good chunk of Columbia. How you might ask? Pablo Escobar’s hippos, which are still hanging around breeding in Columbia […]
In case you’re one of those computer shoppers who instinctively turns up their nose at the very mention of the word refurbished, here are a couple myths worth dispelling. Refurbished equals junk somebody didn’t want. While desktops, laptops, notebooks, Chromebooks and tablets marked as refurbished may have been unboxed at some point, meaning they can […]
Electric bikes aren’t toys. And they aren’t a fad. In fact, more and more communities are starting to catch on that e-bikes are a lot more than an amusing gadget for the tech geek. Following a six-month study, Johnson County, Kansas, home to many Kansas City suburbs, became just the latest U.S. community to allow […]
Whether you’re living in a city that has already taken measures to reduce plastic bag use, the small silver lining of the pandemic has inspired you to make changes, or you’ve already started living a greener lifestyle, reusable produce bags are a great addition to your shopping routine. And if you’re going to invest in […]
