Tree Rings, The Ultimate Historical Record
The overall aspiration of the Center for Mediterranean Archaeology and the Environment is completion of a 10,000-year tree-ring chronology of the entire Mediterranean region.

Night Lighting Of Habitats Damages Plant Communities. Until Now.
Natural plant habitats, particularly those found in places that are normally dark at night, such as caves and forests, are being altered by artificial lighting because the increased illumination helps invasive species to thrive. Light at night also prevents flowers from blooming; decreasing crop yields and spoiling natural beauty spots.

The Bus Shelter That Draws Electricity From Plants
The hub has specially adapted vertical green walls that harvest electrons naturally produced as a by-product of photosynthesis and metabolic activity, and convert them into electrical current.

Oil Palm Waste Can Become Biofuel And Plastics
Leftover plant matter from the production of palm oil could provide a generous source for making biofuels and environmentally friendly plastics. Researchers have developed a fungal culture for use in a cheap and efficient method to transform the waste oil palm material into useful products.

Heating With Corn? Green As Well As Delicious?
Corn is just one choice, though, for a range of stoves now on the market. A long way from the good old cast-iron furnace, these modern appliances can burn fuels including wood, biomass pellets, and even cherry pits.

Tannin Extracted From Bark Replaces Some Petrochemicals
In Finland, tannin could replace, in particular, fossil-based phenols in adhesives used in the wood products industry.

Native Prairie Grass Cleans PCBs from Soil
A type of grass that was once a staple of the American prairie can remove soil laden with PCBs, toxic chemicals once used for cooling and other industrial purposes.

Another Nail In Biofuels’ Coffin?
Turning plant matter into liquid fuel or electricity is so inefficient that the approach is unlikely ever to supply a substantial fraction of global energy demand, the report found. It added that continuing to pursue this strategy — which has already led to billions of dollars of investment — is likely to use up vast tracts of fertile land that could be devoted to helping feed the world’s growing population.

Plants Reveal Their Own Defenses. A New Approach To Pesticides?
Juvenile hormone (JH) plays key roles in insect development, reproduction, and many other physiological functions. .We report on the discovery of potent JH antagonists in plants, which represents an innate resistance mechanism of plants against insect herbivores. These newly discovered plant JH antagonist compounds could be used as the starting material for developing novel insecticides.

Earth’s Vegetation 50-Million Years Ago Revealed At Last
They found something surprising — habitats lost dense tree cover and opened up much earlier than previously thought based on other paleobotanic studies. This is significant because the decline in vegetation cover occurred during the same period as cooling ocean temperatures and the evolution of animals with the type of teeth that feed in open, dusty habitats.
