In order to get more information about the forest here at the Sikundur research station in North Sumatra, I've set up four camera traps, which I'm using to get a better look at the wildlife around the site.
Scientists and other nerds love a good cocktail party fact, and one of my favorites for the holidays is that mistletoe is actually a parasite.
A few months ago, scientists revealed that some plucky mosses in Canada managed to do something long thought impossible: survive a 400-year close encounter with the business end of a glacier, and live to sprout another day.

Today virtually everything we eat is produced from seeds that have been genetically altered in some way. New methods of plant tinkering have emerged over the generations—and so, too, have the fears
Get used to algae blooms, they may be coming to a body of water near you
Editor's note: For The Lawson Trek, journalist Scott Huler is retracing the journey of discovery undertaken by canoe and on foot in 1700-1701 by John Lawson, the first observer to carefully describe and catalogue the flora, fauna, geography and inhabitants of the Carolinas.
In a video, noted scientists debate the connections between ancient climate changes and the emergence of modern human traits.
Scientists knew neochrome was odd before they started rooting around in its family tree. A union of independent proteins — red-sensing phytochrome and blue-sensing phototropin — the super-protein combines two already-great pieces into one fantastic whole that helps plants grow toward dim, filtered light.
Oh what a difference a few years makes. Just four years ago, the rare California shrub known as the Indian Knob mountain balm (Eriodictyon altissimum) was poised to drop off the endangered species list after the threats to its existence had mostly been abated.
